The invention relates to a shock absorber which comprises a hydraulic cylinder, a first one-way damping valve, a second one-way damping valve, a first energy accumulator, a second energy accumulator and a first control valve. Wherein the hydraulic cylinder comprises a cylinder body and a piston, the piston is arranged in the cylinder body in a sliding mode, and an inner cavity of the cylinder body is divided into a rod cavity and a rodless cavity; the rod cavity, the first one-way damping valve, the first energy accumulator, the first control valve, the second energy accumulator, the second one-way damping valve and the rodless cavity are sequentially connected to form a fluid loop. The first one-way damping valve and the second one-way damping valve communicate with the rod cavity and the rodless cavity correspondingly, the first one-way damping valve is suitable for forming damping on oil in the direction that the oil flows out of the rod cavity, and the second one-way damping valve is suitable for forming damping on the oil in the direction that the oil flows out of the rodless cavity; the first control valve is suitable for controlling a flow path between the first energy accumulator and the second energy accumulator to be connected or disconnected. According to the shock absorber and the active suspension system provided by the invention, the controllability and comfort of the suspension system can be improved.

    本发明涉及减振器,包括液压缸、第一单向阻尼阀、第二单向阻尼阀、第一蓄能器、第二蓄能器及第一控制阀;其中,液压缸包括缸体和活塞,活塞可滑动地设置于缸体内,将缸体的内腔分隔为有杆腔和无杆腔;有杆腔、第一单向阻尼阀、第一蓄能器、第一控制阀、第二蓄能器、第二单向阻尼阀、无杆腔依次连接形成流体回路;第一单向阻尼阀和第二单向阻尼阀分别与有杆腔和无杆腔连通,第一单向阻尼阀适于在油液流出有杆腔的方向对油液形成阻尼,第二单向阻尼阀适于在油液流出无杆腔的方向对油液形成阻尼;第一控制阀适于控制第一蓄能器和第二蓄能器之间的流路导通或截止。本发明提供的减振器及主动悬架系统,其能够提高悬架系统的操控性和舒适性。
