Definitions

the invention relates to a loading vehicle with at least one variable-length lifting arm according to the preamble of claim 1.
the loading vehicle embodied as a so-called telescopic loader comprises a drive motor positioned transversely to the longitudinal direction of the loading vehicle, which is assigned to a support frame pointing in the longitudinal direction of the loading vehicle in an area opposite the driver's cab.
the output shaft of the drive motor extends over this side rail structure in the driver's cab-side area and receives at the end of a hydraulic pump, which is connected via a line system with a hydraulic motor integrated in the drive train of the front and rear bogie.
the hydraulic motor is designed so that it drives both the front suspension forming front axle and the rear suspension forming the rear axle and is encapsulated by the side rail for protection against ground contact.
the drive train has a compact design that allows an optimal center of gravity of the Verladehuss and at the same time the use of larger drive units Generation and transmission of large drive power permits.
a particularly compact design is achieved when the drive motor is received transversely to the longitudinal direction of the loading vehicle and the central transmission in the longitudinal direction of the loading vehicle of the support structure and the drive motor and the central transmission via at least one hydraulic drive are interconnected.
the drive motor and the central gear can be optimally fitted into the existing clearances on the loading vehicle, without this affecting the geometry of the other organs of the Verladehuss.
a favorable center of gravity position of the loading vehicle is achieved when the support structure at least one longitudinal beam comprises and the central gear and the drive motor are arranged substantially below the longitudinal member.
a structurally simple implementation of the hydraulic drive is achieved in that the hydraulic drive comprises a drive motor associated hydraulic pump and a central gear associated hydraulic motor and wherein the hydraulic pump and the hydraulic motor are connected to each other via a conduit system.
a high flexibility in the arrangement of the hydraulic pump and the hydraulic motor also results when the line system is formed by hose lines.
the compactness of the drive train can also be further increased if the drive motor comprises at least one output shaft and the hydraulic pump is received and driven by the output shaft of the drive motor.
the compactness of the drive train also further increases in that the hydraulic motor comprises at least one drive connection and the drive connection of the hydraulic motor is seated on an input shaft of the central transmission and drives it.
the central transmission can be designed so that it comprises at least a first and a second output shaft and wherein the first output shaft drives a partial drive train for the front axle and the further output shaft a partial drive train for the rear axle.
the partial drive trains can form a drive train which allow in a proven and known manner a mechanical and / or hydraulic energy transfer to the landing gear.
sub-drive strands each comprise at least one propeller shaft.
the position and compactness of the central transmission can also be in an advantageous development of the invention even steigem, when the input shaft and the one or more output shafts of the central transmission are arranged offset from each other transversely to the longitudinal direction of the Verladehuss. In this way, the central transmission can be at least partially integrated directly into the drive train of the trolleys.
this can be at least partially encapsulated by the longitudinal member of the support structure in an advantageous development of the invention.
a flat construction of the drive system of the loading vehicle and thus a low center of gravity results in an advantageous embodiment of the invention, when the drive motor and the associated hydraulic pump form a drive unit and the spatial extension of the drive unit ends in a drive-side area in front of the drive train of the chassis.
the drive structure according to the invention can be used in telescopic loaders, forklifts and wheel loaders.
FIG. 1 schematically shows the loading vehicle 1 designed as a telescopic loader 2.
the supporting structure 4 in the central position receives a telescopic lifting arm 5 in a central position, to which a tool adapter 6 known per se is assigned.
the lifting arm 5 is pivotally mounted in its rear region of at least one arranged in support flanges 7 transverse to the direction FR pivot axis 8 and wherein the realization of the pivoting movement of the lifting arm 5 below one or more lifting cylinders 9 are assigned to the pivoting of the lifting arm by pressurization or pressure relief 5 allow about said pivot axis 8.
the telescopic extension and retraction of the lifting arm 5 is realized in a known per se and therefore not shown manner by means of further lifting cylinder.
the telescopic lifting arm 5 divides the loading vehicle 1 into a cabin-like area 10 in which the driver's cab 11 is assigned to the supporting frame 3 and a drive-side area 12 in which the drive motor 13 is received by the supporting frame 3.
the support frame 3 takes in a conventional manner a front landing gear 14 formed by a front landing gear 15 and a rear axle 16 formed by a rear landing gear 17.
the supporting structure 4 comprises a longitudinal member 19 which extends in the longitudinal direction 18 of the loading vehicle 1 and to which the front chassis 15 and the rear chassis 17 are fastened.
both the front axle 14 and the rear axle 16 each receive a so-called differential gear 20, 21, which is executed either unlockable or rigid is to drive the wheels 22.
Each of the differential gear 20, 21 is coupled in accordance with the invention via mechanical sub-drive trains 23, 24 with a central gear 25.
the partial drive cords 23, 24 can be designed as propeller shafts 26, 27 known per se. It is within the scope of the invention that the partial drive trains 23, 24 may also comprise hydraulic components for transmitting the drive energy.
the central gear 25 has in the illustrated embodiment, two in the vehicle longitudinal direction 18 facing output shafts 28, 29 which are drivingly connected to the respective propeller shaft 26, 27.
the central transmission 25 is also integrated into the support structure 4 such that its output-side region 30 is essentially integrated in the drive train 31 of the running gear 15, 17 formed by the partial drive trains 23, 24.
the drive-side region 32 of the central transmission 25 comprises at least one input shaft 33 which is likewise aligned in the vehicle longitudinal direction 18. This results in an arrangement in which the input and output shafts 28, 29, 33 point in the vehicle longitudinal direction 18 and are mutually offset transversely to the vehicle longitudinal direction 18 for the central transmission 25.
a hydraulic motor 34 is mounted to drive the central gear 25.
the hydraulic motor 34 is flanged to the central gear 25 via screw connections.
the central gear 25 is fixed in the cabin-side region 10 at least partially below the driver's cab 11 and near the front axle 14 on the support structure 4.
the drive train 31 and the central transmission 25 are at least partially encapsulated by the longitudinal member 19 of the support frame 3. It is within the scope of the invention that the drive train 31 and the central gear 25 can also be completely encased by the longitudinal member 19. In this case, almost no contamination and collision-related wear occurs.
the support structure 4 also receives the drive motor 13, which in the illustrated embodiment via a support frame 35 on the Side member 19 of the support frame 3 is supported.
the drive motor 13 assumes a nearly central position between the trolleys 15, 17 of the telehandler 2.
it is arranged offset in the longitudinal direction 18 of the telescopic loader 2 to the central gear 25 in the drive-side region 12 of the telescopic loader 2. In this way, the central gear 25 and the drive motor 13 to the drive train 31 of the chassis 15, 17 are mutually associated.
the drive units 25, 13 can be arranged close to the longitudinal member 19 of the support frame 3, so that there is a nearly central position of the center of gravity SP between the chassis 15, 17 and thus a great driving stability.
the installation position of the drive motor 13 extends transversely to the longitudinal direction 18 of the telescopic loader 2, so that the output shaft 36 points in the direction of the drive train 31 of the trolleys 15,17.
the output shaft 36 of the drive motor 13 receives in accordance with the invention a hydraulic pump 37, which is flanged on the drive motor 13 by means of screw connections and driven by the drive motor 13 via the output shaft 36 and the hydraulic pump 37 associated drive port 40.
the hydraulic pump 37 of the drive motor 13 and the hydraulic motor 34 of the central gear 25 are connected to each other via a line system 38 for transmitting the hydraulic medium.
the line system 38 advantageously consists of hose lines 39.
the drive units 13, 25, 34, 37 are arranged below the longitudinal member 19.
the drive unit 41 formed by the drive motor 13 and the associated hydraulic pump 37 is arranged in the drive-side area 12 such that the drive unit 41 does not extend into the area of the drive train 31 of the running gears 15, 17. In this way, results in a flat construction of the entire drive structure of the loading vehicle.
the invention is not limited to a loader 1 designed as a telescopic loader 2, but can also, for example, on so-called forklifts or can be used arbitrarily designed wheel loaders to achieve the effects of the invention.
