Steering/suspension integrated system

Abstract

The invention relates to a steering/suspension integrated system comprising vehicle wheels and a vehicle frame. The innovation of the steering/suspension integrated system is further comprising an upper slide bushing assembly, a steering knuckle assembly, a swing arm mechanism and a damping mechanism, wherein the upper slide bushing assembly is in longitudinal sliding connection with the steering knuckle assembly; the upper slide bushing assembly is in horizontal synchronous swinging connection with the steering knuckle assembly via the swing arm mechanism; the damping mechanism is mounted between the upper slide bushing assembly and the steering knuckle assembly; the steering knuckle assembly is fixedly mounted with the vehicle wheels in horizontal direction; and the steering knuckle assembly is mounted with the vehicle frame in a longitudinal sliding manner. The steering/suspension integrated system provided by the invention is simple in structure, rational in design and high in integration, is a mechanical/drive-by-wire general system, and simultaneously has the advantages of being low in cost, and easy to produce, popularize and use.

Description

technical field [0001] The invention belongs to the field of automobiles and relates to a steering / suspension integrated system which is applied to steering and has a large wheel angle range. Background technique [0002] According to whether there is a mechanical connection between the steering wheel and the steering wheel, the steering system can be divided into a conventional steering system with a mechanical connection and a steering-by-wire (SBW) system without a mechanical connection. Steering by wire refers to a control system that connects various components through a communication network. It replaces the traditional mechanical or hydraulic connection, cancels the mechanical connection between the steering wheel and the steering wheel, and occupies less space; the uneven impact of the road will not be transmitted to the driver. On the hand; it can realize the active steering control of the front wheels and improve the active safety of the vehicle. [0003] At prese...

AI Technical Summary

Problems solved by technology

[0003] At present, the conventional steering system with mechanical connection or the steering-by-wire system combining a steering motor with a traditional mechanical steering gear (such as a rack and pinion) are commonly used, but both methods are difficult to be more accurate when the steering angle is large. The problem of satisfying the Ackermann steering principle; therefore, there is a steering system in which two steering motors independently drive the wheels on both sides. prone to interference
