The rear suspension comprises a left suspension body and a right suspension body which are symmetrically arranged and identical in structure, the left suspension body or the right suspension body comprises a swing arm, a steel plate spring and a shock absorber, one end of the swing arm is hinged to an auxiliary frame, the other end of the swing arm is fixedly connected with a brake assembly, the steel plate spring is fixed to the swing arm, and the shock absorber is fixed to the left suspension body or the right suspension body. The two ends of the steel plate spring are hinged to the vehicle body, and the steel plate spring is longitudinally arranged so that the steel plate spring can deform in the X direction. The problems that a traditional independent rear suspension spiral spring is poor in load bearing capacity, the design architecture adopting a non-independent rear suspension for urban transport vehicles, heavy-load pickup trucks, van trucks, hard cross-country vehicles and other vehicle types mainly carrying cargoes contradicts with the comfort requirement are solved, the driving comfort is met, meanwhile, in order to meet the large-load vehicle using scene, the design architecture adopting the non-independent rear suspension is provided, and the design architecture adopting the non-independent rear suspension is provided for the large-load vehicle using scene. According to the spring system, a steel plate spring capable of bearing large loads replaces a traditional spiral spring, and meanwhile the requirement for improving the load of the suspension is met.

    本发明涉及一种后悬架及汽车,后悬架包括对称布置,结构相同的左悬架和右悬架,所述左悬架或者右悬架包括摆臂、钢板弹簧和减振器,所述摆臂的一端与副车架铰接,另一端与制动器总成固定连接,所述钢板弹簧固定在所述摆臂上,所述钢板弹簧的两端均与车体铰接,所述钢板弹簧纵向布置,使得所述钢板弹簧能够沿着X方向形变。本发明解决了传统独立后悬架螺旋弹簧受载荷能力较弱,对于以载货为主的城市运输车、重载皮卡、厢式货车、硬派越野等车型的采用非独立后悬架的设计架构,与舒适性要求相矛盾,不仅满足驾乘舒适性,同时为满足大载荷的用车场景,弹簧系统由能承担大载荷的钢板弹簧代替传统螺旋弹簧,同时满足了提高悬架载荷的要求。
