Integrated steering and suspension system

Abstract

The invention provides an integrated steering and suspension system which comprises a steering motor. The steering motor is in transmission connection with one end of a main pin shaft through a speed reducer; a sleeve is sleeved outside the main pin shaft; the main pin shaft is not in rotation connection with the sleeve; the sleeve can slide axially relative to the main pin shaft; one end of a circular pipe is fixed on the outer surface of the sleeve and the other end is fixed on the side surface of a first connecting block; the first connecting block is fixedly connected with one end of a wheel axle; the other end of the wheel axle is fixedly connected with a wheel hub; the other end of the main pin shaft is fixed with one end of a second connecting block; the other end of the second connecting block is fixedly connected with one end of a damper spring; and the other end of the damper spring is fixedly connected with the first connecting block. The system does not need the independent suspension guide rod system and has a simple structure, the steering space of wheels is greatly improved, and the smaller steering radius can be realized.

Description

technical field [0001] The invention relates to an integrated steering and suspension system which is applied to independent steering by wire and has a large wheel angle range, specifically relates to the realization of the functions of the steering and suspension subsystems and their integration, and belongs to the technical field of automobiles. 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 transmitte...

AI Technical Summary

Problems solved by technology

However, the mechanical linkage between the wheels on both sides limits the angle range of its rotation in space, and it is difficult to meet the Ackermann steering principle more accurately when the turning angle is large. When the vehicle is required to have a small turning radius , the structure of a single steering motor plus a traditional mechanical steering gear is difficult to achieve

As described in the Chinese patent "Independent Steering Device and Independent Suspension System" with the application number 201020182879.3, it adopts the double wishbone (suspension guide rod system) form of the upper wishbone and the lower wishbone in the suspension system. Guided, the steering of the wheels is limited in space, and it is impossible to realize the steering in a small space
