Embodiment 1

[0055] see Figure 1 to Figure 6 , in the embodiment of the present invention, two steering axles 200 are provided, and the two steering axles 200 are arranged one behind the other; There are four control wheels, and each control wheel is rotatably connected to the two ends of the steering bridge 200, and the two power wheels 300 connected to the same steering bridge 200 are always coaxial. The working modes of the vehicle chassis include steering mode, lateral displacement mode and self-balancing mode.

[0056] In the embodiment of the present invention, the two steering axles 200 are respectively rotatably connected to the bottom of the vehicle body 100 near the central axis, and the two steering axles 200 are arranged one after the other. Rotate in the opposite direction to reduce the steering radius of the vehicle; it can also control the two front and rear steering axles 200 to rotate in the same direction so that the vehicle can be displaced laterally, which improves th...

Embodiment 2

[0075] see Figure 6 , in the embodiment of the present invention, two steering axles 200 are provided, and the two steering axles 200 are arranged one behind the other, and four control wheels are provided; the steering axle 200 includes a connecting rod 211 and two steering knuckle arms 212, and the two steering knuckles One end of the arms 212 is respectively hinged with the connecting rod 211 , the other ends of the two steering knuckle arms 212 are respectively connected to the control wheels, and the middle parts of the two steering knuckle arms 212 are both rotatably connected with the vehicle body 100 . The working modes of the vehicle chassis include steering mode and lateral displacement mode.

[0076] In the embodiment of the present invention, the two steering axles 200 are respectively rotatably connected to the bottom of the vehicle body 100 near the central axis, and the two steering axles 200 are arranged one after the other. Rotating in the opposite direction...

Embodiment 3

[0091] In the embodiment of the present invention, there are two steering axles 200, the two steering axles 200 are arranged one behind the other, and there are four control wheels; At the bottom of the body 100, the axial directions of all the truck wheels are parallel. The operating modes of the chassis of the vehicle include steering modes.

[0092] In the embodiment of the present invention, the two steering axles 200 are respectively rotatably connected to the bottom of the vehicle body 100 near the central axis, and the two steering axles 200 are arranged one after the other. Rotating in the opposite direction reduces the turning radius of the vehicle; additional support bridges and load-carrying wheels can improve the running stability and load-carrying capacity of the vehicle body 100 . Preferably, the truck wheel is a power wheel 300 with a built-in brushless hub motor, so that the supporting bridge and the truck wheel can also provide additional power for the operat...

Abstract

The invention provides a vehicle chassis and a control method thereof. The vehicle chassis comprises a vehicle body, a control system, steering axles and at least three power wheels, the control system is in signal connection with all the power wheels and is used for monitoring and controlling the rotating speed of all the power wheels, each steering axle comprises a steering axle body and two hubbearings which are separately positioned at the two ends of the steering axle body, the steering axles are rotationally connected to the vehicle body and can freely rotate at any angle relative to the vehicle body in the horizontal direction, the power wheels are connected to the vehicle body or the hub bearings, at least two power wheels are connected with the hub bearings of the steering axlesin a one-to-one correspondence mode, and the power wheels connected to the hub bearings are used for providing the steering force for the rotation of the steering axles relative to the vehicle body. According to the vehicle chassis, the power wheels are used for providing the steering force of the vehicle chassis, so that the occupied vehicle inner space and the weight are greatly reduced, the dead weight of the vehicle body caused by the vehicle chassis in the straight running process is avoided, and the carrying capacity and the safety of the vehicle are improved.

Description

technical field [0001] The invention belongs to the technical field of motor vehicles, and in particular relates to a vehicle chassis, a vehicle with the chassis and a control method for the vehicle chassis. Background technique [0002] Most of the traditional carrier vehicle chassis adopt a front-drive drive structure in which the engine of a single power source drives the front wheels to steer, and transmits the power to the corresponding power wheels through a complex deceleration system and transmission system. Obviously, the structure of this chassis is complex, and its steering power The wheels still take up a lot of weight and the interior space of the car body in a non-working state. [0003] The new type of electric carrier chassis, such as some AGV (Automated Guided Vehicle, automatic guided vehicle), began to adopt a two-wheel differential steering chassis structure, but this type of chassis must require at least one auxiliary universal driven wheel. The gravity...
