Description

structure of a truck

technical field

The invention relates to the technical field of automobile transportation, in particular, it refers to a truck structure.

Background technique

With the improvement of living standards, more and more automobiles are used in people's lives. In particular, the development of the logistics industry and the construction of expressways have promoted the application of automobiles in logistics and transportation. At present, the most widely used trucks in the logistics industry are composed of a tractor and a semi-trailer. The wheels of the tractor provide driving and steering, which is the driving wheel; the wheels of the semi-trailer neither provide driving nor steering, and are driven wheels. The truck of this structure has the following disadvantages:

1) The length of the semi-trailer needs to be customized according to the length of the loaded objects, resulting in high cost and inconvenience.

2) Due to the long body and large load capacity, the girder at the bottom of the semi-trailer is long and thick, and the self-weight of the vehicle is large, which consumes energy.

3) When turning, the wheels on the semi-trailer cannot do pure rolling, but both roll and slide, resulting in large friction, large loss, and short tire life.

4) Since the car can only be driven and steered by the front driving wheel, and the tractor and the semi-trailer are flexibly connected (the tractor and the semi-trailer are not in a straight line when turning), it is very inconvenient and difficult to operate when reversing. .

5) The car is completely driven by the front driving wheel, and the axle load of the driving wheel is small, so the driving wheel will slip.

Contents of the invention

The technical problem to be solved by the present invention is to provide a truck structure, which can overcome the above defects, has low cost and is easy to use.

To achieve the above object, the present invention is achieved in that,

In the above-mentioned vehicle body, at least one set of wheels is a driving wheel, and the above-mentioned driving wheel is connected to the front of the vehicle through a signal line.

Preferably, all the wheels in the above-mentioned vehicle body are driving wheels, and the driving wheels are connected to the front of the vehicle through signal lines.

The above-mentioned truck structure further includes an operating device, the operating device is arranged on the last vehicle body, and the wheels of the last vehicle body are driving wheels.

Preferably, the above-mentioned operating device is a joystick, an operating panel or a remote operating device.

In the above vehicle body, at least one set of wheels are steerable wheels, and the steerable wheels are connected to the front of the vehicle through signal lines.

Preferably, all the wheels in the above-mentioned vehicle body are steerable wheels, and the steerable wheels are connected to the front of the vehicle through signal lines.

Preferably, the above-mentioned body length is three meters.

After adopting the above method, when in use, first rigidly connect the front of the vehicle to the first vehicle body, and then determine the number of vehicle bodies according to the needs, and rigidly connect the vehicle bodies. This structure can be adjusted according to the length of the loaded objects. Select the number of sections of the attached vehicle body; due to the present invention, it is a rigid connection, so that the whole truck is a whole vehicle, shortening the length of the whole vehicle, and at the same time, solving the problem of convenient retreat. Compared with existing vehicles, its The cost is low and the use is convenient.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

As shown in Fig. 1, the present invention discloses a truck structure, comprising a headstock 1, a vehicle body 2, wheels 3 and bolt assemblies 4, wherein:

In this embodiment, the headstock 1 and the body 2, and between the body 2 and the body 2, are rigidly connected by bolts. The two ends of the rear part of the headstock 1 are provided with connecting blocks 11, 12, and the connecting blocks 11, 12 are respectively With bolt holes. In addition, the rigid connection between the headstock 1 and the body 2 can also be realized in other ways.

In this embodiment, there are five vehicle bodies 2, each of which has the same structure. Its length is three meters.

As shown in Fig. 2, connecting blocks 21, 22 are provided at both ends of the rear portion of the vehicle body 2, and bolt holes 211, 221 are provided on the connecting blocks 21, 22; 24. The connecting blocks 23, 24 are provided with bolt holes 231, 241; the so-called corresponding position means that they are on the same axis as the connecting blocks 23, 24 and the bolt holes of the connecting blocks 21, 22 when combined.

The wheels 3 are arranged under the front 1 and the vehicle body 2 . In this embodiment, the ones below the front 1 are driving wheels, and all the wheels under the vehicle body 2 are driving wheels, and the driving wheels are connected to the front 1 through signal lines. The wheels are all steering wheels, and the steering wheels are also connected to the headstock 1 by a signal line. The headstock 1 has a steering wheel, and the bottom of the vehicle body 2 is a steering wheel, which can make all the wheels turn independently, and the sliding phenomenon of the wheels disappears. Preferably, the wheel of the last wheel is both a driving wheel and a steering wheel, which is more convenient when going backwards. In addition, the best solution is to have two rows of wheels, that is, to ensure that the distance between the two rows of wheels is small (3 meters at best), so that the bending moment of the girder is small and the self-weight is reduced.

Furthermore, because the headstock 1 has a drive wheel, the vehicle body is all a drive wheel, which can solve the problem of slippage of the driving wheel that the only drive wheel axle load is small.

The setting of the wheels can improve or reduce the difficulty of the backward operation. Optimally, an operating device can also be set on the last section of the vehicle body, which is a joystick, an operation panel or a remote control operation device, and the last section of the vehicle body can be used as the front of the car to further facilitate the operation of the car in reverse. When the driver uses the remote control device to reverse the car, it can be operated from the rear.

The bolt assembly 4 includes bolts 41 and nuts 42 .

When in use, as shown in Fig. 3, connect the connecting blocks 21, 22 at the front end of the first vehicle body with the connecting blocks 11, 12 at the rear of the headstock 1, pass the bolts 41 through the bolt holes of the above-mentioned connecting blocks, and use nuts 42 locking, so as to realize the rigid connection between the headstock 1 and the vehicle body 2; then, connect the connection blocks 21, 22 at the rear of the previous body 2 with the connection blocks 23, 24 at the front of the rear body 2, and then connect the bolts 41 passes through the bolt hole and is locked with nut 42. Thereby realizing the rigid connection of vehicle body and vehicle body.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
