Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a work vehicle, particularly a fire engine, and more particularly, it has a chassis frame that extends through the chassis frame, and a vehicle that extends in the longitudinal direction of the vehicle. At least one main carrier is provided, on which are arranged at least two axles spaced apart from each other in the longitudinal direction of the vehicle, a drive motor, optionally a fire pump, a driver's cab, gears and other additions. It relates to work vehicles, in particular fire trucks, in which the device is mounted on a shaft.

[Conventional technology]

Various chassis for use in service vehicles, especially fire engines, are already known. And in particular, the drive motor for driving a motor vehicle of this type can be placed between the extending main carrier, approximately on one side, above the front axle or in the area of the front axle, or on the rear axle. It is known to be placed in the region of or behind this rear axle. Particularly in the case of the chassis currently in use, manufactured as a chassis series for regular trunks such as dump trucks, long-distance trailer trucks, etc., there is a simple way to adapt this chassis to the requirements for work vehicles. It is difficult to adapt them to the various usage requirements and conditions. Chassis supplied in series often require extensive adaptations and modifications in order to approximately meet the requirements placed on chassis in the field of work vehicles.

In the case of other known chassis for fire engines (Intensive Techniques (Intensive Techniques) Based on a research report also known as an orbit study, the drive motor for a 4X4 vehicle (which has two axles with a single tire attached to each, and can drive all wheels) generally drives the front axle. Its driven part is located under the upper edge of the chassis frame.Such a structure provides better access to the drive motor, since the axle, shaft gear and This is because the drive shaft makes access from below difficult.At the same time, vibrations and the exhaust heat of the drive motor are transmitted to the cab on its 7 sides, which causes very strong loads during work travel. It can be hung in the driver's cabin.

Furthermore, according to GB 885,689 it is also known to arrange a support device for the drive motor between the two axles of the chassis. Since the drive motor is suspended between the two main carriers of the chassis frame from above, the upper edge of the drive motor is below the upper edge of the main carrier of the chassis frame. Although this provides a favorable center of gravity position for the motor in the chassis frame, it is hardly possible to maintain the required ground clearance. This is because the driven part of the drive motor is already approximately at the same level as or below the axial center point of the axle. This particularly makes the placement of the distributor gear difficult.

[Problem that the invention seeks to solve]

The object of the invention is to provide a working vehicle which can be used in a wide range of applications and which allows for a wide variety of variations in the position and structure of the center of gravity with respect to the desired drive method.

[Means and effects for solving the problem] This problem of the present invention is solved by the features of claim 1. The surprising advantages of this seemingly relatively simple method are as follows.

That is, the drive device, and therefore the drive motor auxiliary unit, can be selectively provided with a gear arrangement, or a front axle gear, a rear axle gear or an all-wheel gear arrangement, or a front axle steering the rear axle or both axles, Nevertheless, it is possible to provide a favorable center of gravity and freedom of access in a variant of the usual equipment arrangement of work vehicles.

According to another feature of the invention, the features of claim 2 are provided. In this case, an arrangement of this type has the advantage that in working operation a favorable load distribution with a favorable center of gravity position for operation is obtained. at the same time,
Easy access from the front of the vehicle to the auxiliary units and, in particular, to the terminals of the individual extinguishing agent pipes if a extinguishing agent pump is present.

This means that the pipes protruding to the side from the vehicle will not get in the way when other work vehicles pass by. Furthermore, it is possible to accommodate an operator who operates the auxiliary unit in the driver's cab in order to monitor the function of the auxiliary unit. The working conditions for the operator are thereby improved. For example, in the case of fire pumps, the injection of foam or other agents through remote control means is required to remain in the operator's cabin during work, protected from adverse weather conditions, and to enable the auxiliary units to perform their functions. This is because you can concentrate on mixing. Furthermore, improved sound absorption in the cab allows for better understanding of other work units via radio. However, it is also possible to optionally equip the work vehicle with front-wheel drive, rear-wheel drive or all-wheel drive independently of this. Another wood advantage is that the auxiliary unit can be placed within the wheel of the vehicle, protecting it from damage.

Furthermore, the characteristic part of claim 3 is possible,
A favorable floor height is thereby achieved in the area of the driver's cab. In addition, by providing a kick-up in the carrier in the area behind the front axle, a corresponding space can be used between the two main carriers or below the two main carriers, so that the motor can be moved to the desired height position. The main carrier can be fixed to the chassis frame via a support device, and the position of the main carrier can be adapted at will to accommodate various equipment parts, such as fire pumps, tanks, etc.

Furthermore, the features of claim 4 are advantageous. This gives enough space in the area of the front axle to draw a small turning circle, but at the same time the driven part of the drive motor directly follows the front axle and extends into the area below the edge of the chassis frame. I can do it. At the same time, another advantage of this method is that the chassis frame is widened in the region of the rear axle, where the extinguishing agent pump or extinguishing agent container is located, as the case may be, so that the ground plane of the structure is widened.

The embodiments shown in the characterizing part of claim 5 are advantageous. By configuring the main carrier in this way, it is very easy to place the drive motor and the equipment compartment or equipment module accommodating the equipment in the lowest possible position, thereby providing good lateral stability and a good center of gravity. You can get the location. However, at the same time, access to equipment parts becomes easier and their placement becomes easier.

Furthermore, the features of claim 6 are also possible, so that equipment modules or extinguishing agent containers, etc., can be easily removed, for example after arriving at the work site, and an empty space for replenishment runs or for the introduction of new equipment objects is also possible. You can insert a frame.

According to a further embodiment, the features of claim 7 are provided, with which a good further transmission of power within the chassis frame is possible.

However, the features of patent claim 8 are also possible. By arranging the support device for the drive motor in the manner according to the invention, it is possible to adapt the requirements from the center of gravity or the method of access to the motor to the various ways in which different structures can be freely attached to this type of work vehicle. A favorable compromise is reached. In particular, by arranging the drive motor between the two axles, it is ensured that it can be accessed equally well from above and from below, which is hardly hindered by shaft gears, intermediate gears, etc.

At the same time, it is possible to drive both axles via the drive shafts at corresponding height positions from the central distributor gear, thus realizing all-wheel drive and obtaining a corresponding ground clearance. Another advantageous aspect of this method is that the cab and working capacity of the drive motor are substantially unaffected by vibrations, noise generation or heat radiation. The basic structure of the chassis can therefore be of general use and convenient for the working vehicle, and the chassis can be easily adapted to the various working purposes of the working vehicle.

Within the framework of the invention, the features of patent claim 9 are also possible. The arrangement of the followers facilitates the distribution of the drive power to the individual axles and the mounting of the drive axles.

The embodiments of the invention are particularly advantageous in the characterizing part of patent claim 10. By locating the auxiliary unit in the area above the front axle and the drive motor in the area of the chassis frame projecting beyond the rear axle, the chassis frame is loaded approximately symmetrically with respect to the axle. and the resulting favorable load distribution.

At the same time, direct access from the rear side of the service vehicle facilitates access for maintenance and repair of the drive motor. Furthermore, it is possible to arrange the extinguishing agent tank in the area between the two axles and thus as close as possible to the center of gravity of the work vehicle, which also improves cornering driving behavior. Furthermore, there is no need to build an expensive see-saw type driver's cab.

Furthermore, it is advantageous in the case of the characterizing part of claim 11 that it is possible to centrally distribute the drive power and to provide the work vehicle with selective front-wheel drive, rear-wheel drive or all-wheel drive. can be equipped with.

According to the invention, the features of claim 12 are also possible. Due to the special construction of the gear module, the space required for drive and driven gear is very small.
or by configuring the gear module accordingly.
Intermediate transmission from the power shift gear to the intermediate shaft gear is omitted.

Furthermore, the features of claim 13 are also possible. This leaves sufficient area above the upper side of the chassis frame for accommodating structures and facilitates servicing by providing access to the drive part from below. This also leaves space outside the main carrier for accommodating structures, so that structures projecting laterally and downwardly from the main carrier, such as tanks or the like, can be mounted on the main carrier.

According to another embodiment of the invention, the features of claim 14 are provided. This makes it possible to obtain in a simple manner, without disassembly, the case of a simple auxiliary unit suitable for different conditions of use inside and outside the wheel of the motor vehicle. Thus, for example, if an auxiliary unit breaks down, it is possible to quickly replace it, which in the case of a work vehicle is always task 1! It is very important to be fully prepared.

Furthermore, the features of claim 15 are also possible. As a result, it is possible in a very simple and advantageous manner for the work vehicle to select the drive method that best corresponds to the working conditions, ie front-wheel drive, rear-wheel drive or all-wheel drive.

Furthermore, advantage is given in the case of the characterizing part of patent claim 16. This is because it makes it possible to utilize the ground contact area that can be used to transmit frictional forces and to obtain a large contact area. By arranging the leaf spring between the main carrier and the axle, the lateral sides of the axle are well guided.

According to the invention, the features of claim 17 are also possible. Thereby, when driving around curves at high speeds, the structure can be swung about its longitudinal axis against the action of centrifugal force by means of a corresponding compressive force supply of the spring element; The distance between the chassis frame and the ground plane can be adapted to different working conditions, for example driving on asphalt roads or driving in the countryside or to stationary conditions during work. By sinking the chassis frame during operation, the overall height of the vehicle can be reduced and access to equipment parts can be facilitated. Furthermore, if a plurality of operating means are provided on the chassis frame or on the work vehicle for operating the exhaust and filling valves and the spring elements, the desired position of the chassis frame relative to the ground plane can be adjusted independently of the respective position of the operator. can be adjusted.

Furthermore, the feature of claim 18 is also possible, whereby a space can be left between the main carriers for arranging equipment, a drive shaft, a power distribution gear, etc. Although the volume of the device object is generally large, the amount of M is not so large, so it can be placed above the chassis frame.

Furthermore, it is advantageous in the case of the characterizing part of patent claim 19. This is because the operating speed, in particular in the curve area, is thereby increased by the method according to the invention.
C) During the working journey, a uniform delay is maintained, independent of the number of braking strokes, which can be fully exploited even in straight travel sections and nevertheless last only for a very short time.

Other embodiments are provided based on the features of claim 20. This makes it possible to mount the equipment part as low as possible in the chassis frame or to provide an extinguishing agent pump that is easily accessible and has a lower approach height. Nevertheless, the low-mounted equipment parts are protected from damage by a bumper, which can be removed during work in order to improve access. Based on the features, this embodiment is advantageous, since it makes it possible to combine the advantages of providing a trailer chain with the advantages of providing a bumper.

Embodiments are also possible based on the characteristic part of claim 22, whereby the height of the frame does not have an adverse effect on the height of the arrangement of the extinguishing agent pump.

BRIEF DESCRIPTION OF THE DRAWINGS In order to understand the invention better, the invention will now be described in detail using examples shown in the figures.

In FIG. 1, a chassis 2 for a work utility, in particular a fire engine, is shown. The chassis includes a chassis frame 3 which is supported via an axle 3.4 and wheels 6 on the wheel contact surface or roadway. The chassis frame extends from the area in front of the front axle 4 via the two axles 4.5 to the area beyond the rear axle 5. A drive motor 8 is supported via a support device 9 approximately midway between the two axles 4 and 5 of the chassis frame 3. This support bag W9 is attached to the chassis frame 3 in the following manner, that is, the driven device 10 of the drive motor 8 is connected to the grounding point 1 of the axle 4.5 and the wheel 6.
The upper side of the wheel on the opposite side of wheel 1] is fixed so as to be placed at an intermediate height between 2 and 2. In this case, the driven device 10 is further located below the upper edge 13 of the main carrier 14 constituted by the chassis frame 3 . In the region of the axle 5 behind this main carrier 14, a kick-up consisting of two bends 15 and 16 is formed, and in this kick-up there is a displacement in the direction of the contact surface 7 of the wheel. The frame portion 17 of the main carrier 14 parallel to this plane is continuous. A fire pump 18 is arranged on this frame portion 17 of the main carrier 14. The displacement of the frame portion 17 of the main carrier 14 toward the ground contact surface of the wheels prevents access to the fire pump 18 or other extinguishing agent pumps, or to units that require manual handling, such as hose reels. becomes easier.

The frame parts arranged on both sides of the two folds 15 and 16 each form an angle 19 of less than 180°.

A gearing device 20 is directly attached to the drive motor 8, and this gearing device is coupled via power transmission gears 21, 22 to shaft gearing devices t23, 24' for power transmission. It is also possible to form the power transmission gears 21 , 22 with universal shafts, in which case the dimensions of the universal shaft are determined in such a way that each power transmission gear 21 , 22 is able to transmit the entire torque of the drive motor 8 . Ru.

However, the gear system 20 and the shaft gear system! The power transmission between 23 and 24 can also take place via hydraulic transmissions, such as, for example, hydraulic pumps, hydraulic lines and hydraulic motors.

Furthermore, as is clear from FIG. 1, the axles 4, 5 are connected to the chassis frame 3 via leaf springs 25. The front axle 4 can be controlled by a steering wheel 26. Furthermore, FIG. 1 shows that a device support frame 29 is disposed between an operator's cab 27 attached to the chassis frame 3 and an equipment or device room 28. For example, an air filter 30, a compressed air container 31, a spare wheel 32 and, for example, a fuel or lubricant tank 33 can also be arranged on this device support frame 29.

Thereby, between the main carrier 14 of the chassis frame 3, the drive motor 8, the gearing 20 and the transmission gears 21, 22 or, for example, a universal drive unit 35 which connects the fire pump 18 in order to take off the drive power directly from the drive motor. A space is left for inserting a transmigrating gear 34 such as a shaft.

As is apparent from FIG. 2, the central longitudinal axis 36 of the drive morph 8 is laterally displaced from the longitudinal axis 38 of the vehicle by an amount indicated by 37. The axis of the drive device 39 driving the vehicle 4.5, which is located parallel to the longitudinal axis 38 of the vehicle, is
From the longitudinal axis 38 of the vehicle, the center longitudinal axis 36 is moved by an amount not shown at 40.
is displaced in the opposite direction. As is further clear from this figure, the transmission gears 21 , 22 are arranged between the two main carriers 14 of the chassis frame 3 .

Furthermore, as is clear from this figure, two bent portions 41 and 42 are provided in the area behind the axle 4 of the chassis frame 3 in a plane parallel to the ground plane 7 of the wheel.
A kick-up of two main carriers 14 is formed.

As a result, the distance between the main carriers is widened in the area adjoining the wheels 6 of the front axle 4 compared to the area above the front axle 4. This facilitates installation of the drive device and gear device. Double bending part 4
An angle of less than 180° is formed in each of 1°42. A drum brake is arranged between the axles 4, 5 and the wheels 6.

In Figures 3 and 4, a chassis 4 for a working vehicle 2 is shown.
5 other embodiments are shown. Particularly, as is clear from FIG.
It extends to an area above and opposite to the contact surface 7 of the wheel. The other frame part 48 , which extends to the rear of the rear axle 5 , is displaced upwards from the wheel contact patch 7 compared to the frame part 47 by approximately the height 49 of the superstructure. The frame portion 48 (FIG. 4) thereby extends to the top corner of the superstructure of the vehicle 2. The rear axle 5 is supported by a main carrier 51 forming the chassis frame 46 via a columnar support 50 provided on the rear frame portion 48 . Main carrier 510 frame parts 47 and 48
are connected to one another via a frame part 52, which extends in particular obliquely. In the region of the transition points between the frame parts 47 and 52 and 48 and 52 respectively, bends 53 are formed. As you can see from the side-by-side comparison of Figures 3 and 4, there is a three-dimensional bend here. This is because the frame portion not only has a bend 53 in a plane extending perpendicular to the wheel contact plane and parallel to the longitudinal axis 38 of the vehicle, but also has a bend 53 in a plane extending parallel to the wheel contact plane 7. Also the bent part 54
, 55 are provided. Therefore, the main carrier 51 has a three-dimensional kick-up. Furthermore, the chassis frame 46 is provided with a frame section 56 which has the same height as the frame section 47 but extends approximately in the region of the vehicle longitudinal axis 38, which frame section 56 is connected to the front and rear axles 4 and 5. Extends to the center of the wheel. This frame portion 56 accommodates the drive morph 8 or the gear device 20 and a fire extinguishing agent container 57, a portion of which is shown by a dotted line. The extinguishing agent container is rotatably supported on the frame portion 48 and the frame portion 56 of the main carrier 51 via a spring fixing member 58 so as to be freely movable with respect to the chassis frame 46. This fixing member 58
can be formed by an elastic rubber member or a leaf spring or similar member.

The driver's cab 27 is connected to the chassis frame 46 in the area of frame parts 47 and 52.
, and the equipment compartment or equipment module 59 is suspended in a simple manner on a frame section 48 passing through the upper corner area of the main carrier 5. By suspending the equipment module 59 in this way, the equipment module is not obstructed by the frame portion passing below, and is placed as close as possible above the wheel contact surface 7 in accordance with the required minimum ground clearance. be able to. This greatly facilitates access to equipment targets and devices.

In addition, in a simple technical way, as shown for example in the case of five average equipment modules, it is possible to install a working vehicle, for example by providing a height adjustment drive 61, such as a cylinder-piston arrangement, and an intermediate frame 60. In order to be used for installing other equipment modules, the equipment module 59 can be lowered or removed within the guides of the intermediate frame 60 into the lowered position at the point of use, which is shown in dotted lines.

Instead of providing a height adjustment drive 61 and an intermediate chamber 60, a schematically illustrated height adjustment drive 62 can be used to move the height adjustment drive 62 along the columnar support 50 relative to the frame part 48 of the main carrier 51. There is also a way to adjust the height of the axle 5 automatically, so that the height of approach to the fire pump 18, which may be arranged in the area of the equipment module 59 and the frame part 56 projecting beyond the axle 5 at the rear, is also possible. reduced.

By providing the main carrier 51 with a three-dimensional kick-up, a free floating area for the mounting of the front axle 4 and the wheels 6 of the front axle 4 and a correspondingly favorable turning angle for the working task is obtained. However, it is also desirable to be able to steer not only the wheels 6 of the front axle 4 but also the wheels of the rear axle 5 in order to carry out curve driving in a manner suitable for economical tire wear.

In order to improve the view, the exterior of the 3M has been removed, and the driver's cab 27 and some equipment modules 59 are omitted in FIG.

Similarly, the arrangement of the fire pumps is only schematically illustrated. The connection of the chassis frame 46 to the cabin, module or other structure is typically achieved by elastic links.

Furthermore, also in the case of the chassis frame 46 having this structure, the driven device 10 of the drive motor 8 can be easily arranged at a height midway between the axle and the upper end edge of the wheel. for that,
Optionally, the frame part 56 can be displaced or bent upwards or downwards from the frame part 47 perpendicularly to the contact surface 7 of the wheel.

In another embodiment shown in FIGS. 5 and 6, the chassis frame 63 is provided with two main carriers 64, which are located between the front axle 4 and the rear axle 5. It is set up in the form of a gate in the area. Furthermore, the main carrier 64 is curved both in height and laterally in the mutually facing regions of the front and rear axles 4 and 5, so that the main carrier 64 has bends 65 pointing in opposite directions.
, 66 are formed, and these jointly form a kick-up. Thereby, the frame parts 67, 68 can extend in the region of the front or rear axles 4, 5, between the wheels 6 of these axles, just above the axles 4, 5. This facilitates the fixing of the axle 4.5 and the necessary units. In the area between axles 4.5,
The portal-shaped arrangement of the main carrier 64 allows the equipment module 59 to be suspended in the chassis frame 63 from below. Therefore, the effect of easy access and reduction of the extraction height can be obtained.

It is clear that if the chassis frame 63 is formed according to the configuration of FIGS. 5 and 6, it is advantageous to arrange the drive motor 8 in the region above the rear axle 5. There is no need to further provide a support member for the drive motor 8. This is because the drive motor can be supported directly on the frame portion 68. At the same time, this frame part 6
Alternatively, a fire pump 18 or other fire extinguishing agent pump or the like may be placed on a frame portion 69 that is displaced downward from this frame portion toward the wheel contact surface 7. Thereby, even in the area directly adjoining the axle 5, equipment or devices,
Auxiliary or rescue means can be arranged in accordance with the conditions of use of the working vehicle.

In this embodiment, the extinguishing agent container 57 can be suspended in the center of the equipment module in a similar way to the equipment module 59, but via a cross beam between the two main carriers. A driver's cab 27 can be arranged in the area above the front axle 4 .

FIG. 7 shows that another embodiment of the present invention can also be used to form a kick-up in the chassis frame 70 in the direction of the wheel contact patch 7. The frame portions 71 of the two main carriers 72 that extend parallel to each other are
Between the front axle 4 and the rear axle 5 there are two bends or a kick in the main carrier 72 which descends downwards towards the contact surface of the wheels, so that in the mutually facing regions of the two axles the main carrier 72 has two bends or one kick. Up is provided. In this case, the drive motor 8 and the fire pump 18 can each be fastened via simple fastening devices to the main carrier 72 and to the equipment module or cab 27 or to other structures, such as, for example, rotating ladders, lifting platforms, etc. can be directly attached to the main carrier of the chassis frame 70, in which case the overall height of this type of fire engine or work vehicle 2 can be reduced by displacing the frame part 71 in the direction of the wheel ground plane 7. I can do it.

Furthermore, in FIG. 7, the axles 4 and 5 and the chassis frame 70
It is shown that a compression means spring member 73, for example an air spring member, can be arranged between. This compression means spring member 73 is connected to the exhaust and fill valve 75.
It is connected to a compression means supply device 74 via. In order to activate the exhaust and fill valves 75, the operating means-76 are installed, for example, in the cab 27 or at various locations in the structure.
For example, it is provided in the area of the fire pump 1B or in the area of the equipment module.

Thereby, the height of the working vehicle, which is already very low, can be reduced to tP1 even closer to the wheel contact patch by lowering the chassis frame 70 and using the compression means spring member 73. can.

What is important in all the embodiments shown in FIGS. 1 to 7 is the following. That is, as schematically illustrated in the figure, depending on the structure of the chassis frame, the drive motor 8 can be positioned at a desired relative height position with respect to the chassis frame, or between the upper side of the axle and the wheel 6 opposite to the ground plane 7. can be placed in between. The design and structure of the equipment room or the equipment module can be freely selected within the framework of the invention. Equipment modules or equipment rooms can therefore be formed from profiled pipes and fitted with cladding, doors or sliding doors or gates.

Furthermore, in order to make the overall method of the invention easier to understand, it is shown in FIG. 4 that the work 2 or fire engine according to the invention can be provided with a bumper 77. The trailer connector 7 is attached to this bumper 77.
8 can also be provided. For example, when the fire pump 18 is set as low as possible by the embodiment of the chassis frame according to the present invention, in order not to obstruct access to the suction terminals, etc., when arriving at the place of use, the bumper 7
7 together with the trailer coupler 78 can also be rotated about an axis perpendicular to the ground contact angle 7 of the wheels. Alternatively to this type of arrangement, the support forming the bumper can be removed completely by removing the locking port, or it can also be pivoted around any other axis, such as a parallelogram lever arrangement. .

In FIG. 8, a work station 101 is shown with a chassis frame 102 of a driver's cab 103 and utility structures 104 (which may include a fire extinguishing agent container 105). The operator's cab 103 and the utilization structure 104 are shown simply by thin ring lines, a portion of which has been cut away, so that the drive system according to the invention for driving this type of work can be viewed. It is.

As is clear from FIGS. 8 and 9, the chassis frame 102
consists of two main carriers 106, 107 which are parallel to each other and extend in the longitudinal direction of the vehicle. The main carriers 106, 107 of the chassis frame 102 are supported on a front steerable axle 108 and a rear axle 109 via conventional spring arrangements, for example leaf springs or compression springs. Wheels 110 are mounted on both axles 108 and 109.
is mounted on a shaft, and the tires are heavily fitted. The chassis frame 102 is attached to both main carriers 106 and 107 in a region @111 that projects forward from the front axle 10B.
In between supports an auxiliary unit 112, which in this case is a fire extinguishing agent pump 113. The extinguishing agent pump 113 is connected in power transmission with a gearing module 115, which is likewise arranged between the two main carriers 106, 107, via a universal shaft 114 which serves as a drive coupling. In this case, the universal shaft 114 is the power shift gear device 1
It is coupled with 17 auxiliary driven devices 116. In addition to the power shift gear 117, the gear module 115 includes a Humberta gear 118 and an intermediate shaft gear 1 housed in a dedicated casing.
Contains 19. The gear module 115 is connected to both main carriers 106, 107 via a swing damping member 120.
It is supported on a horizontal beam 121 fixed to. As clearly shown in FIG. 8, the driven part 1 of the intermediate shaft gear 119
22, 123 are connected to shaft gears 126, 127 via universal shafts 124, 125. With this configuration, an all-wheel drive vehicle is obtained,
Here both axles 108 and 109 can be driven independently of each other. The dimensions of the universal shafts 124, 125 and the intermediate shaft gear 119 and shaft gears 126, 127 are such that the total torque (which is used to drive the work object 101) through either the two universal shafts 124 or 125 is
is selected so that it can be taken out. Work errands 1
The 01 can be driven in front-wheel drive, rear-wheel drive, or all-wheel drive.

The human power shaft 128 is coupled to a drive motor 130 via another universal shaft 129.

The drive motor 130 is journalled on the main carriers 106, 107 in a region 131 that projects beyond the rear axle 109 of the chassis frame 102.

The driven part 132 of the drive motor 130 is connected to the chassis frame 1.
It is arranged at the height of the upper edge 133 of 02.

Due to the structure of the drive or the arrangement of the individual uni-nods, the areas 111, 131 of the chassis 102 which project beyond both axles 108, 109 are loaded approximately equally. By separating the two main carriers 106 and 107, the drive motor 130, gear module 115, and auxiliary unit 12 can be placed close to the ground contact surface 134 of the wheel. Furthermore, both axles 108, 10
The upper edge 133 of the main carrier 106, 107 between 9
A space is left above and to the outside to accommodate part of the structure or cabin. Therefore, the extinguishing agent container 10
5 is preferably arranged in the area between the two axles 108,109. Then, the weight of the gear module 115 and the extinguishing agent container 1050 will be distributed approximately evenly to both axles 108, 109, thereby providing a neutral operating condition of the work 101.

However, for example and without departing from the invention,
For example, the drive motor 130 can be directly connected to the gear module 1.
15, or placed between the gear module 115 and the rear axle 109, and the extinguishing agent container 105 is connected to the work item 1.
It can also be placed in the rear area of 01.

This type of arrangement of the drive motor is shown in dotted lines in FIG.

In FIG. 10 the installation of the auxiliary unit 112, in this case the extinguishing agent pump 113, is shown in detail.

The extinguishing agent pump is connected to the intermediate frame 13 via the swing damping member 135.
6, this intermediate frame is guided inside the main carrier 106, 107 via rollers 137. The intermediate frames 136 can be secured to the main carrier 106, 107 by safety ports 138 in their respective final positions.

As a result, after the front opening/closing part 139 of the driver's cab 103 is swung in the direction not shown by the arrow 140, the auxiliary unit
112 to the fire extinguishing agent pump 113 to the ring part 141 of the automobile.
Can be transported to areas outside of the

If the extinguishing agent pump is mounted on an intermediate frame 136 of this type without being fixed to the chassis frame 102, the universal shaft 114 can be formed as a telescopic universal shaft, as schematically shown in FIG. Auxiliary equipment 112 without interruption
can be taken in and taken out.

Instead of the extinguishing agent pump shown in FIGS. 8 to 10, it is also possible to arrange any other auxiliary units, such as, for example, a generator, a hydraulic system, etc. However, it is also possible to use an auxiliary unit (112) instead of the intermediate frame 136 which is handled using rollers.
Each of the other bearings supporting the chassis frame 1, for example, the chassis frame 1
Of course, it is also possible to provide a parallelogram-shaped lever device or the like fixed to the main carrier 106, 107 of 02.

In FIG. 11, the gear module 115 is arranged between the two main carriers 106 and 107 of the chassis frame 102. In FIG. As is clear from the figure, the horizontal beam 121 is U
It is formed in a letter shape, and both upper free ends thereof are connected to the main carriers 106 and 107 of the chassis frame 102 via a vibration damping member 120.

This allows the gear module 115 to move with elastic damping relative to the chassis frame 102 in multiple spatial directions.

In FIG. 12, the drive motor 130 is similarly connected to both main carriers 106 and 107 of the chassis frame 102 via the motor support member 142 using the vibration damping member 120.
It is shown supported above.

The motor support member 142 is formed such that the driven part 132 of the drive motor 130 is located approximately in the right side area of the upper edge 133 of the main carrier 106, 107 or in the area of the intermediate frame removed by the main carrier. .

In FIG. 13, an embodiment of the drive circuit is shown, in which the drive motor 130 is attached directly to the gear module 115. Furthermore, converter gear 118 and power shift gear 117 are clearly shown in this drawing. The main gear shaft 143 is coupled to the auxiliary drive device 116 via a coupling 144 that can be operated electromagnetically. Thereby, a power utilization device, for example a fire extinguishing agent pump 11, which is supplied with power via the auxiliary drive 116
3 or other auxiliary means 112, such as a generator 145.
can be turned on and off by applying a load.

However, as schematically illustrated, a hydraulic pump 146 is attached to the secondary drive 116 and via a flexible pressure vibrator 148 that passes the hydraulic pump to the hydraulic drive block.
Hydraulic motor 14 attached to the input shaft of generator 145
7 can be connected. Generator 145 may drive external lighting sources or other operating equipment.

The conharc gear 118 is composed of a pump gear, a turbine gear, and a guide gear disposed therebetween. The rotational speed of the turbine is high, approximately 80% of the rotational speed of the pump.
%, the turbine moment is approximately equal to the pump moment. At this point the converter converter is automatically closed. In addition, the conharc gear 118 is provided with a brake coasting device, which connects the drive and turbine shafts when the automatic starts to skid to provide G-rubbing so that the braking effect of the motor can be fully utilized. belongs to. The multiple reversing device is provided with a hydraulically driven stacking force/knob ring 149 in a hack gear structure that can be controlled by applying a load. All gears mesh continuously. The gear control is designed as an electro-hydraulic circuit, which can be either a preselection circuit, i.e. a circuit in which the individual processes can be preselected as required by means of a drying switch, or an automatic circuit, i.e. a circuit in which the required process can be preselected using a drying switch. can each be designed as a circuit that can be automatically selected according to the instantaneous operating situation. The oil supply of the converter and the circuit takes place via a gear pump, which is mounted on the drive shaft or main gear shaft 143 subordinate to the motor in the gear module 115.

Within the scope of the invention, it is also possible to use other respective gears instead of the gears of the above-mentioned configuration and also to use, for example, mechanically switched gears with mechanical couplings. be. The coupling 144 used for the auxiliary drive 116 is also not connected in the embodiment shown in FIG.

The structure of main carrier of chassis frame 102] 06.107 can also be freely selected within the framework of the present invention.

Therefore, instead of a main carrier that runs through in one piece, it is also possible to use a main carrier that consists of several pieces, for example in the region of the bend or in the middle extending longitudinally. They can be connected to each other through bonding in other areas.

It goes without saying that the drive device according to the present invention can be advantageously used in work vehicles in other fields, such as lift trucks, public vehicles, etc., instead of being used in fire engines.

The direction of travel is generally indicated by arrow 150 in the figure.

As is clear from FIGS. 8 and 9, both main carriers 106 and 107 extend parallel to each other over the entire length of the vehicle and are bent only in a plane that extends perpendicular to the wheel contact surface 134. A portion 151 is formed. A region 111 of the chassis frame 102 that continues from the bent portion 151 and protrudes further forward from the front axle 108 is bent toward the wheel contact surface 134. This facilitates the insertion of the auxiliary unit 112 (in this case the fire pump ll3). As is clear from Figures 9 and 10,
By bending the region 111 of the chassis frame 102, the auxiliary unit 112 can be easily pulled out beyond the front of the work vehicle 102.

Another advantage of the construction of the main carriages 106 and 107, which extend without bends in a plane running parallel to the contact plane of the wheels, is that both the front axle 108 and the rear axle 109 (if necessary) It can be formed to be maneuverable,
This further facilitates the operation of the work vehicle 101 as desired.
