The invention discloses a suspension system capable of rapidly changing the height of a vehicle body and a working method thereof.The suspension system comprises a shock absorber and a hydraulic lifting mechanism, a lower supporting plate used for being connected with an axle or wheels is arranged at the bottom of the shock absorber, the top of the shock absorber is connected with the vehicle body, and the hydraulic lifting mechanism comprises an oil cylinder assembly and a hydraulic control system; a plurality of telescopic upper piston rods are arranged at the top of the oil cylinder assembly, the movable ends of the upper piston rods are connected with the vehicle body, a plurality of telescopic lower piston rods are arranged at the bottom of the oil cylinder assembly, and the movable ends of the lower piston rods are connected with the lower supporting plate. The oil cylinder assembly is arranged in the limited space between the vehicle body and the axle or the wheels, the extending directions of the upper piston rod and the lower piston rod on the oil cylinder assembly are opposite, large-range height adjustment of the vehicle body can be achieved, different running conditions of the vehicle can be met, the trafficability of the vehicle in different environments is effectively improved, and the vehicle safety is improved. And the use scene of the vehicle is widened.

    本发明公开了一种快速改变车身高度的悬挂系统及其工作方法,该悬挂系统包括减震器和液压升降机构,减震器的底部设有用于与车桥或车轮连接的下支板,减震器的顶部与车身连接,液压升降机构包括油缸总成和液压控制系统,油缸总成的顶部设有若干可伸缩活动的上活塞杆,上活塞杆的活动端与车身连接,油缸总成的底部设有若干可伸缩活动的下活塞杆,下活塞杆活动端与下支板连接。本发明在车身与车桥或车轮之间的有限空间内设置油缸总成,油缸总成上的上活塞杆和下活塞杆的伸展方向相反,可实现车身的大范围高度调节,能够满足车辆不同的行驶条件,其有效提高了车辆在不同环境下的通过性,拓宽了车辆的使用场景。
