The invention discloses a rear wheel suspension system and a vehicle, and the rear wheel suspension system comprises an auxiliary frame which comprises a front cross beam, a longitudinal beam and a rear cross beam, and the front cross beam, the longitudinal beam and the rear cross beam define a suspension space; a front upper control arm; a front lower control arm; a rear upper control arm; a rear lower control arm; the steering knuckle is used for positioning a wheel center axis, and the wheel center axis is located in front of the center of the suspension space; and the electric drive assembly is arranged in the suspension space. According to the rear wheel suspension system and the vehicle, the steering knuckle is located on the side close to the front cross beam of the auxiliary frame, the wheel side system is connected to the steering knuckle, the steering knuckle positions the wheel center axis of the wheel side system, the wheel center axis is located in front of the center of the suspension space of the auxiliary frame, and the electric drive assembly is arranged in the suspension space; the space occupied by the electric drive assembly deviates backwards, and the chassis battery installation space, occupied by the electric drive assembly, in front of the auxiliary frame is reduced. The method can be applied to the technical field of suspension system design.

    本发明公开了一种后轮悬架系统及车辆,后轮悬架系统包括:副车架,其包括前横梁、纵梁、后横梁,前横梁、纵梁、后横梁围成悬置空间;前上控制臂;前下控制臂;后上控制臂;后下控制臂;转向节,转向节定位轮心轴线,轮心轴线位于悬置空间中心的前方;电驱组件,其设于悬置空间。本发明的后轮悬架系统及车辆,使转向节位于靠近副车架前横梁的一侧,由于轮边系统连接于转向节上,转向节定位轮边系统的轮心轴线,轮心轴线位于副车架悬置空间中心的前方,且电驱组件设于悬置空间中,使电驱组件占用的空间往后偏移,减少电驱组件占用副车架前方的底盘电池安装空间。本发明可应用于悬架系统设计技术领域中。
