The invention relates to the technical field of vehicles, in particular to a rear suspension steering system and a vehicle. The rear suspension steering system comprises a rear axle, a first suspension connecting rod, a second suspension connecting rod and a driving device, and the driving device is fixed to the frame and hinged to the two ends of the rear axle through the first suspension connecting rod and the second suspension connecting rod so as to provide acting force opposite in the front-back direction for the two ends of the rear axle, and therefore the rear axle can rotate. The active rear axle steering function of a non-independent suspension is achieved, the turning radius of the vehicle during low-speed turning is reduced, the maneuverability of the vehicle is improved, and the handling stability of the vehicle during high-speed turning is improved; meanwhile, the structure is simple, the occupied space is small, and an existing vehicle can be conveniently transformed. Meanwhile, the rear suspension steering system does not weaken the bearing capacity of the rear axle. Meanwhile, the rear suspension steering system not only has a position steering angle control mode, but also has a force steering angle control mode.

    本申请涉及车辆技术领域,尤其是涉及一种后悬架转向系统及车辆。后悬架转向系统包括后桥、第一悬架连杆、第二悬架连杆和驱动装置,驱动装置固定于车架上,驱动装置通过第一和第二悬架连杆与后桥的两端铰接,以为后桥两端提供前后方向相反的作用力,从而使后桥能够旋转,实现非独立悬架的主动后桥转向功能,减小车辆低速转弯时的转弯半径,提高车辆机动性,并提高车辆高速转弯时的操纵稳定性;同时,结构简单,占用空间小,便于对现有车辆进行改造。同时,本申请的后悬架转向系统不会削弱后桥的承载能力。同时,本申请的后悬架转向系统,不仅具有位置转角控制模式,还具有力转角控制模式。
