A multi-connecting-rod suspension structure applied to a four-wheel independent control electric vehicle comprises a steering support connected to a vehicle body and a suspension system, and the suspension system is rotationally connected with the steering support through a fixing frame; the suspension system comprises a rear beam rigidly connected with the fixing frame, the upper end and the lower end of the rear beam are hinged to a connecting rod and a lower swing arm respectively, and the other end of the connecting rod and the other end of the lower swing arm are hinged to a steering knuckle. Steering of the vehicle body is achieved through rotary connection between the fixing frame and the steering support, and jumping of the vehicle body in the vertical direction is achieved through a four-connecting-rod mechanism formed by hinging the rear beam, the lower swing arm, the steering knuckle and the connecting rod. The two motions do not interfere with each other on a mechanical structure, coupling between steering and wheel jumping of the electric vehicle is eliminated, the vehicle body is more stable when the steering and the wheel jumping of the electric vehicle are performed simultaneously based on the suspension structure, and a driver can control the vehicle more conveniently.

    一种运用于四轮独立控制电动车的多连杆悬挂结构,包括连接在车身上的转向支架,以及悬挂系统,所述悬挂系统通过固定架与转向支架旋转连接;其中所述悬挂系统包括与固定架刚接的后梁,后梁的上端与下端分别铰接连杆和下摆臂,连杆和下摆臂的另一端分别与所述转向节的铰接;车身的转向通过固定架与转向支架之间的旋转连接实现,而车身竖直方向的跳动通过后梁与下摆臂、转向节、连杆铰接形成的四连杆机构实现;两个运动在机械结构上互不干涉,消除了电动车转向与车轮跳动之间的耦合,基于该悬挂结构电动车在转向和车轮跳动同时动作时车身更加稳定,更有利于驾驶员对车辆进行控制。
