The invention discloses a rear wheel steering assembly, a rear suspension system and a vehicle, and relates to the technical field of vehicle steering. The rear wheel steering assembly comprises a driving assembly and two pull rod assemblies, the driving assembly comprises a driver and a driving shaft, and the driver is connected with the driving shaft and is configured to be capable of driving the driving shaft to move in the axial direction of the driving shaft; the two pull rod assemblies are connected to the two ends of the driving shaft respectively, each pull rod assembly comprises a joint fork and a control arm, one end of the joint fork is connected to the driving shaft, the other end of the joint fork is provided with a rotating shaft, one end of the control arm is provided with a lantern ring sleeving the rotating shaft, the other end of the control arm is connected with a steering knuckle, and the control arm can rotate around the rotating shaft to drive the steering knuckle to move in the vertical direction. When the control arm is subjected to external acting force, compared with the yoke, the lantern ring or the control arm is easier to be damaged, and the damage state comprises deformation and fracture. Buffering and force unloading effects are achieved through deformation and/or fracture of the lantern ring or the control arm, and the risk that the driving assembly is damaged is reduced.

    本发明公开了一种后轮转向组件、后悬架系统及车辆,涉及车辆转向技术领域。后轮转向组件包括驱动组件和两组拉杆组件,驱动组件包括驱动器和驱动轴,驱动器与驱动轴连接,并被配置为能够驱动驱动轴沿驱动轴的轴向移动;两组拉杆组件分别连接于驱动轴的两端,每组拉杆组件分别包括节叉和控制臂,节叉一端连接于驱动轴,另一端设有转轴,控制臂一端设有套设于转轴的套环,另一端连接有转向节,控制臂能够绕转轴转动,以带动转向节沿上下方向移动,当控制臂受到外部作用力时,相较于节叉,套环或控制臂更加容易出现损伤状态,损伤状态包括变形和断裂。本发明通过套环或控制臂的变形和/或断裂起到缓冲和卸力的作用,降低了驱动组件受损的风险。
