A combined spring compensation suspension device for a vehicle, comprising a free spring (6), a compensation spring (3), a compensation spring pre-tightening device (2), a vibration isolation block (4), a light damping shock absorber (7) and a guide mechanism (5), wherein the free spring (6), the compensation spring (3) and the light damping shock absorber (7) are arranged between a frame (1) and the guide mechanism (5), the compensation spring (3) is connected to the frame (1) or the guide mechanism (5), the compensation spring pre-tightening device (2) is installed at the upper end of the compensation spring (3), and the guide mechanism (5) is used to connect a wheel to a vehicle body; and an elastic element on the vehicle suspension device is composed of the free spring (6) and the compensation spring (3), a suspension load has a compensation interval nearby a static deflection stroke of the suspension, when the suspension load is changed in the compensation interval, the stroke is not changed or is slightly changed, only when the suspension load exceeds the compensation interval, the suspension stroke can be changed, and the controllability and the comfort of the vehicle adopting the design can be simultaneously improved. |
