The invention provides a lifting suspension system of a vehicle, the vehicle and a vehicle body height adjusting method.The lifting suspension system comprises a lifting damping device and an oil supply device, the lifting damping device comprises a floating piston, a damping piston and an outer cylinder barrel, the floating piston divides an inner cavity of the outer cylinder barrel into a lifting cavity and a damping cavity which are isolated from each other, the damping piston is located in the damping cavity, and the oil supply device supplies oil to the lifting cavity; a first oil supply connector is arranged on the side wall of the lifting cavity and used for allowing hydraulic oil of the oil supply device to enter the lifting cavity and discharging the hydraulic oil in the lifting cavity, and a second oil supply connector is arranged on the side wall of the damping cavity and used for allowing the hydraulic oil of the oil supply device to enter the damping cavity and discharging the hydraulic oil in the damping cavity. Thus, on the premise that the strength of the lifting suspension system is guaranteed, the needed lateral space is small, the arrangement difficulty and the occupied space are reduced, the bearing capacity of lateral force and stress in other directions is large, the adjusting response speed is high, the response is sensitive, and the adjusting precision is high.
本公开提供了一种车辆的举升悬架系统、车辆及车身高度调节方法,包括举升减震装置和供油装置,举升减震装置包括浮动活塞、减震活塞和外缸筒,浮动活塞将外缸筒的内部腔体分隔成相互隔离的举升腔和减震腔,减震活塞位于减震腔中,举升腔的侧壁上设置有第一供油接口,用于供所述供油装置的液压油进入举升腔以及排出举升腔内的液压油,减震腔的侧壁上设置有第二供油接口,用于供油装置的液压油进入减震腔以及排出减震腔内的液压油。这样,在保证举升悬架系统的强度的前提下,所需要的侧向空间小,降低的布置的难度和占用空间,而且侧向力和其他方向应力的承受能力大,调节响应速度快,反应灵敏,调节精度高。
