Variable shaft height wheel

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...

AI Technical Summary

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
