Bimodal automobile suspension device

The invention discloses a bimodal automobile suspension device and relates to the field of automobile suspension devices. By arranging two shock absorbing springs between a top plate and a transitional plate and between the transitional plate and a bottom plate, when an automobile drives on a flat road, the second shock absorbing spring does not exert an effect under the action of a shrinkable supporting rod and a force received by a wheel hub only can be transferred to the automobile body quickly through the first spring, so that the operability of the automobile is improved. When the automobile drives on an uneven road, the second shock absorbing spring exerts an effect under the action of the shrinkable supporting rod and the force received by the wheel hub can be transferred to the automobile body through the first and second springs, so that the stability of the automobile is improved. Therefore, the automobile has the optimum comprehensive performance of operability and stabilityin all conditions. 本发明公开
