The invention discloses an active suspension system. The active suspension system comprises a right damper, a left damper, a pump and a control valve system. Each of the right damper and the left damper includes a damper housing, a piston rod, and a piston mounted on the piston rod. The piston is arranged for sliding engagement inside the damper housing such that the piston divides the damper housing into a first working chamber and a second working chamber. The pump includes a pump inlet and a pump outlet. The control valve system is connected in fluid communication with the first and second working chambers of the right damper, the first and second working chambers of the left damper, the pump inlet, and the pump outlet. The control valve system has several different arrangements of fluid flow paths providing different operating modes for the active suspension system.
本发明公开了一种主动悬架系统,该主动悬架系统包括右阻尼器和左阻尼器、泵和控制阀系统。该右阻尼器和该左阻尼器中的每者包括阻尼器壳体、活塞杆和安装在该活塞杆上的活塞。该活塞被布置成在该阻尼器壳体内部滑动接合,使得该活塞将该阻尼器壳体分成第一工作室和第二工作室。该泵包括泵入口和泵出口。该控制阀系统与该右阻尼器的该第一工作室和该第二工作室、该左阻尼器的该第一工作室和该第二工作室、该泵入口以及该泵出口进行流体连通地连接。该控制阀系统具有为该主动悬架系统提供不同工作模式的流体流动路径的若干不同布置。
