The invention belongs to the technical field of automobiles, and particularly relates to an electric toe-in control arm, a five-connecting-rod rear suspension system and a vehicle, the electric toe-in control arm comprises a toe-in control arm fixing pipe, a toe-in control arm neck bush used for being connected with an auxiliary frame is arranged at one end of the toe-in control arm fixing pipe, and the other end of the toe-in control arm fixing pipe is an open end; the ball screw kinematic pair comprises a screw rod and a nut, the screw rod penetrates through the open end of the toe-in control arm fixing pipe, one part of the screw rod is located in the toe-in control arm fixing pipe, the other part of the screw rod is located outside the toe-in control arm fixing pipe, and the screw rod located outside the toe-in control arm fixing pipe is connected with a toe-in control arm outer connector; the toe-in control arm outer joint is provided with a toe-in control arm outer lining used for being connected with a steering knuckle. And the driving device is used for driving the nut to rotate so as to realize the axial displacement of the screw rod. The length of the toe-in control arm can be dynamically and timely adjusted, the design difficulty and cost of the auxiliary frame are reduced, and the weight of the whole vehicle is reduced.

    本发明属于汽车技术领域,尤其是涉及一种电动前束控制臂、五连杆后悬架系统及车辆,电动前束控制臂包括:前束控制臂固定管,其一端设置有用于与副车架连接的前束控制臂内衬套,前束控制臂固定管的另一端为敞口端;滚珠丝杆运动副,包括丝杆和螺母,丝杆穿过前束控制臂固定管的敞口端,丝杆的一部分位于前束控制臂固定管内,丝杆的另一部分位于前束控制臂固定管外,位于前束控制臂固定管外的丝杆连接有前束控制臂外接头,前束控制臂外接头上设置有用于与转向节连接的前束控制臂外衬套;以及驱动装置,用于驱动螺母转动,以实现丝杆沿轴向位移。本发明可动态适时调节前束控制臂的长度,降低了副车架的设计难度及成本,减轻了整车重量。
