The invention discloses a combined spring compensation suspending device. The device comprises a free spring, a compensating spring, a compensating spring pre-tightening device, a vibration isolating block, a light damping shock absorber, a guide mechanism, wherein the free spring, the compensating spring and the light damping shock absorber are arranged between a car frame and the guide mechanism; the compensating spring is connected with the car frame or the guide mechanism; the compensating spring pre-tightening device is mounted at the upper end of the compensating spring; the guide mechanism is used for connecting car wheels with a car body. The combined spring compensation suspending device is specifically characterized in that an elastic part on a suspending device of a car is composed of the free spring and the compensating spring; the suspension load has a compensation region nearby a static deflection travel of the suspension; when the load bore by the suspension is changed within the compensation region, the travel is not changed or barely changed; when the suspension load is beyond the compensation region, the suspension travel is changed; a vehicle adopting the design can be improved in both operability and comfort.
