Problems solved by technology

The rim of the wheel is fixed with spokes, and most of the spokes and rims are an integrated structure, which cooperates with the drive shaft to realize driving. However, the road conditions of the vehicle are relatively complicated, and obstacles of various sizes will be encountered on the driving road, such as gravel, Bumps, etc., especially engineering vehicles, mostly operate in more complex field conditions, so the height of the vehicle's chassis directly affects the ability of the vehicle to pass through obstacles, and the driver needs to judge whether it can pass safely
If the driver is inexperienced, makes a wrong judgment, and a large obstacle collides with the chassis of the vehicle to cause a major safety accident, the traditional vehicle is powerless against the large obstacle ahead, and it is not an active control strategy for regular obstacle avoidance
At the same time, the driving method of traditional cars is to drive the wheels through the engine, and the power transmission path is relatively complicated. With the development of smart cars and electric vehicles, new electric driving methods are urgently needed, so it is urgent to adjust the chassis height of the vehicle in a wide range to adapt to Road conditions in various situations and electric wheel drives that meet the needs of the development of smart car electrification

Embodiment 1

[0032] The working principle of the present invention is as follows: the drive wheel 3 rotates to drive the wheel rim 2 to rotate by applying a torque through the full-plate motor 4, and the supporting system and the central shaft 7 only perform translational motion on the inner plane of the wheel rim, and do not rotate with the rotation of the wheel. The support system is mainly composed of six pairs of hydraulic cylinders, of which 2 pairs of hydraulic cylinders 6 are installed vertically, and the other 4 pairs of hydraulic cylinders are installed at intervals of 60 degrees along the circumference of the central axis. When the central axis needs to be raised, the control strategy is used to control the hydraulic pump to control the input and output hydraulic pressure of the six pairs of hydraulic cylinders. The upper three pairs of hydraulic cylinders 6 perform contraction movement, and the lower three pairs of hydraulic cylinders 6 perform elongation movement. According to th...

Embodiment 2

[0037] refer to Figure 8 , the hydraulic support structure is a hydraulic cylinder and a U-shaped frame 15 fixedly connected with the piston rod 5, the bottom outside of the U-shaped frame 15 is fixedly connected with the piston rod 5, and the structure of two legs of the U-shaped frame 15 Same construction as earrings. The hydraulic support structure is 3 hydraulic cylinders and a U-shaped frame 15 fixedly connected with the piston rods of the hydraulic cylinders, and the structure of the two legs of the U-shaped frame 15 is the same as that of the earrings.

[0038] Connecting the central axis of the variable axle height wheel of the present invention to the axle of the automobile can adjust the chassis height of the vehicle more conveniently, pass obstacles ahead smoothly, and do not need to detour and change lanes, which is different from traditional fixed At the same time, the driving mechanism is installed on the inside of the wheel, which is different from traditional...

Abstract

The invention relates to a variable shaft height wheel which comprises a rim, a central shaft, a support system and a driving system, wherein the central shaft, the support system and the driving system are fixedly connected with an axle; the support system comprises two hydraulic support structures which are positioned on diameters perpendicular to the rim on an automobile chassis; the two hydraulic support systems are symmetrically and fixedly connected with the central shaft; the inner ring of the rim is divided into two half circles by the two hydraulic support structures; at least one hydraulic support structure which is fixedly connected with the central shaft is uniformly distributed in each half circle; the driving system comprises driving wheels and a full-disc motor; two motor shafts of the full-disc motor are connected with lugs of the hydraulic support structures through bearings; the driving wheel is arranged on the full-disc motor in a sleeving manner; outer teeth are arranged on the outer circumference of the driving wheel; inner teeth in transmission matched with the outer teeth on the driving wheel are arranged on the inner ring of the rim. The variable shaft height wheel has the advantages of being compact in structure, high in security, good in stability, relatively low in cost, easy in precise control, and the like.

Description

technical field [0001] The invention belongs to the technical field of transportation vehicle tires, and in particular relates to a variable axle height wheel. Background technique [0002] Wheels are widely used in all walks of life, especially in the field of transportation. Wheels are an indispensable part. As the only part of the vehicle in contact with the road, the vehicle's driving safety, handling stability and comfort Performance such as performance depends largely on the interaction between the wheel and the ground, so the importance of the wheel is self-evident. [0003] It is the wheel structure that determines the function and performance of the wheel. The traditional wheel structure is the cooperation between the tire and the rim. The chassis height of the vehicle is basically determined. It can only rely on the vehicle suspension system to control the vibration and amplitude, and only the height floats within a small range of the vehicle body. And it is uncon...
