Abstract
The disclosure relates to the technical field of vehicles, and particularly provides a multi-link independent suspension for a vehicle that includes a subframe and a steering knuckle. In order to solve the problem of reduced adjustment efficiency caused by mutual restraining of linkages of an existing multi-link independent suspension when a camber angle is adjusted, the multi-link independent suspension includes a spring control arm that is configured to adjust a camber angle of a wheel center. The multi-link independent suspension also includes a front upper control arm and a rear upper control arm. A central axis of the front upper control arm intersects with a central axis of the rear upper control arm at a Q point, and the Q point has the same coordinate as the wheel center in an X direction; and a motion centerline between the front upper control arm and the rear upper control arm coincides with a projection of a central axis of the spring control arm on an XY plane, so that a movement of the spring control arm has no effect on an upper control arm system when the camber angle is being adjusted. The steering knuckle only rotates about an X axis so as to drive a tire to rotate…
