Problems solved by technology

[0008] There are many problems in the technical solution disclosed above: under the normal driving condition with the wheel steering angle between ±35°, the dynamic characteristics of the suspension are not good enough. Suspension dynamics; steering knuckles or in-wheel motor housings and other parts have poor stress conditions; steering mechanisms need to provide greater force and consume greater power

Abstract

The invention provides an independent driving, steering and suspending system which comprises an in-wheel motor, a wheel hub unit, a first steering knuckle, a spring shock absorber, a lower cross arm, a second steering knuckle, a first steering actuator and a second steering actuator, wherein the in-wheel motor is used for driving a wheel to rotate; the wheel hub unit is used for supporting the rotation of the wheel and the in-wheel motor; the first steering knuckle is used for supporting the wheel hub unit, and can rotate around a first king pin axis formed by a first king pin; the spring shock absorber is used for supporting the wheel to jump up and down; the lower cross arm is used for guiding when the wheel jumps up and down; the second steering knuckle is used for supporting the first king pin, and can rotate around a second king pin axis formed by an upper fulcrum of the spring shock absorber and a spherical hinge of the lower cross arm; the first steering actuator is used for driving the first steering knuckle to rotate; and the second steering actuator is used for driving the second steering knuckle to rotate.

Description

technical field [0001] The invention relates to the technical field of vehicle chassis, in particular to an independent drive, steering and suspension system, in particular to an independent drive, steering and suspension system with large steering angle characteristics. Background technique [0002] The steering angle of existing vehicles is mostly between ±35°, and the steering angle of some special-purpose vehicles can reach ±45°. The steering angle is mainly limited by several aspects. The first is the transmission shaft. The transmission efficiency is low when the angle is too large, and there is also interference with adjacent parts. Secondly, the steering gear, especially the steering tie rod has a limited stroke, and there is also the problem of interference with other components. Then there is the suspension, especially the lower arm, which can interfere with the wheels. [0003] In order to meet the design requirements of large steering angle characteristics, th...
