后轮随动转向技术应用研究综述

A Review on the Applied Research of Rear Wheel Compliance Steering

在阐述后轮随动转向技术原理与实现方式的基础上,从悬架衬套研究、后轮随动转向车辆的横向稳定性研究以及后轮随动转向技术在大型车辆上的应用研究3个方面,系统地分析了随动转向技术的研究现状及存在的不足,指出了目前应用于悬架系统的橡胶衬套与液压衬套研究中尚需进一步考虑的问题,以及结合磁流变液或磁流变弹性体等智能材料衬套开展车辆智能化时后轮随动转向的研究方向。

Firstly, the principle and implementations of rear wheel compliance steering technology （RWCST） are introduced. Then research status as well as shortcomings of RWCST are analyzed systematically from three aspects, i.e., suspension bushing, lateral stability of the vehicles with RWCST, and the application of RWCST in large sized vehicles. Finally, the issues to be further considered in the application research of rubber bushing and hydraulic bushing in suspension system are summed up, and the research trend of bushing made of smart materials, which combine magnetorheological fluids or magnetorheological elastomers, in the rear wheel appliance steering for intelligent vehicles are also identified.
