The invention relates to the technical field of vehicles, in particular to a multi-connecting-rod independent suspension for a vehicle. In order to solve the problem that when the camber angle of an existing multi-connecting-rod independent suspension is adjusted, rod systems are mutually restrained, and the adjusting efficiency is reduced, the multi-connecting-rod independent suspension for the vehicle comprises an auxiliary frame and a steering knuckle; a spring control arm of the multi-connecting-rod independent suspension is arranged to be a camber angle capable of adjusting a wheel center; the central axis of the front upper control arm and the central axis of the rear upper control arm intersect at a Q point, and the Q point is the same as the X-direction coordinate of the wheel center; the movement center lines of the front upper control arm and the rear upper control arm coincide with the projection of the central axis of the spring control arm on the XY plane, so that when the camber angle is adjusted, the movement of the spring control arm has no influence on an upper control arm system, the steering knuckle only rotates around the X axis to drive the tire to rotate on the X axis, the camber angle of the tire is changed, the toe-in angle is not influenced, so that the camber angle of the tire can be adjusted more simply, and the number of influenced rod systems is smaller.
本发明涉及车辆技术领域,具体提供一种用于车辆的多连杆独立悬架。为解决现有的多连杆独立悬架在调节外倾角时,杆系互相约束,造成调节效率下降的问题,本发明的用于车辆的多连杆独立悬架,车辆包括副车架和转向节;多连杆独立悬架的弹簧控制臂设置成可调节轮心的外倾角;前上控制臂的中轴线与后上控制臂的中轴线相交于Q点,Q点与轮心的X向坐标相同;前上控制臂与后上控制臂的运动中线与弹簧控制臂的中轴线在XY平面的投影重合,使得外倾角调节时弹簧控制臂的移动对上控制臂系统没有影响,转向节仅绕X轴转动进而带动轮胎在X轴转动,使轮胎的外倾角形成角度的变化,而不对前束角产生影响,使得轮胎的外倾角调节更简单,影响的杆系更少。
