The invention discloses a rear suspension system with a passive rear wheel follow-up steering function. The rear suspension system comprises a torsion beam mechanism and rear suspension mechanisms symmetrically arranged at the two ends of a torsion beam body respectively, and the torsion beam mechanism comprises the torsion beam body and torsion beam front bushings symmetrically arranged on the front end face of the torsion beam body; the rear suspension mechanism comprises a corbel located at the bottom of the torsion beam body, a corbel front bush and a corbel rear bush which are arranged on the corbel respectively, a front bush mounting bracket rotationally matched with the corbel front bush, and a rear bush mounting bracket rotationally matched with the corbel rear bush, the front bush mounting bracket is connected to the inner wall of the torsion beam body, and the rear bush mounting bracket is connected to the outer wall of the torsion beam body. And the rear bushing mounting bracket is connected to the rear end face of the torsion beam body. The stress of the rear wheels is changed through the rear suspension mechanism, and therefore it is guaranteed that tires do not lose stability and drift; the problems of stability and road holding performance of vehicles running at a high speed are solved, and the smoothness of turning of rear wheels is guaranteed.

    本发明公开了一种具有被动后轮随动转向功能的后悬架系统,包括:扭转梁机构、以及分别对称设置在扭转梁本体两端的后悬架机构,扭转梁机构包括扭转梁本体、以及对称设置在扭转梁本体前端面的扭转梁前衬套;后悬架机构包括位于扭转梁本体底部的托臂、分别设置在托臂上的托臂前衬套和托臂后衬套、与托臂前衬套转动配合的前衬套安装支架、以及与托臂后衬套转动配合的后衬套安装支架,前衬套安装支架连接在扭转梁本体的内壁,后衬套安装支架连接在扭转梁本体的后端面。本发明通过后悬架机构改变了后轮的受力,从而保证轮胎不失稳甩尾;解决高速行驶的车辆稳定性和抓地性问题,还保证了后轮转弯的顺畅性。
