Independent suspension device capable of achieving steering drive function

The invention relates to an independent suspension device capable of achieving a steering drive function. The independent suspension device comprises an upper control arm, a lower control arm, a hub hanger, a gas bag and a damping device. The upper control arm and the lower control arm are hinged to the upper end and the lower end of the hub hanger through steering ball heads correspondingly. The hub hanger can rotate along a straight line formed by connecting the upper and lower steering ball heads. When the hub hanger steers, a real main pin does not exist, a drive system can be arranged on the axis of a hub wheel center of the hub hanger, accordingly the independent suspension device can have steering and driving functions, steering and driving can be independently achieved and also can be simultaneously achieved, and the product flexibility is high. 本发明涉及种可实现转向驱动功能的独立悬架装置，包括上控制臂、下控制臂、轮毂挂架、气囊和减振器，所述上控制臂和下控制臂分别通过转向球头与所述轮毂挂架的上下两端铰接，且轮毂挂架可绕所述上下两个转向球头中心连成的直线转动。本发明轮毂挂架转向时没有实体主销，轮毂挂架的轮毂轮心轴线上可以布置驱动系统，从而使得本发明具有转向和
