[0031] In the embodiment, the vehicle suspension structure can be applied in vehicle. The lower vehicle body 100 is integrally pressure casting molding structural member. The steering knuckle 500 is directly rotatably connected on the lower vehicle body 100 through the upper swing arm assembly 200 and the lower swing arm assembly 300, without needing to set auxiliary frame for connecting the lower vehicle body 100 on the lower vehicle body 100. The side, which is away from the lower vehicle body 100 of the steering knuckle 500, is used for installing brake disc and hub bearing and the like components. Wheel is installed on the steering knuckle 500 through hub bearing. The steering knuckle 500 can rotate at a certain angle relative to the lower vehicle body 100, so that wheel can rotate relative to the lower vehicle body 100, and then realizes the steering of wheel. The damping assembly 400 is installed between the steering knuckle 500 and the lower vehicle body 100. The steering knuckle 500 can swing up and down relative to the lower vehicle body 100 at a certain angle, so as to provide sufficient damping stroke for the damping assembly 400.

[0032] It can be understood that the material of the lower vehicle body 100 includes but is not limited to one or more of aluminum alloy, steel or carbon fiber. The knuckle 500 can include but is not limited to an aluminum alloy forged structure. The upper swing arm assembly 200 or the lower swing arm assembly 300 can be cast or forged into shape.
