The invention discloses a hydraulic suspension system with a mode switching function, comprising: an actuator comprising a liquid inlet and a liquid outlet; the hydraulic energy supply device can output pressure liquid; the electro-hydraulic servo valve comprises a cut-off station and a communication station, and the actuator is communicated with the hydraulic energy supply device through the electro-hydraulic servo valve; the liquid inlet and the liquid outlet are respectively communicated with the electro-hydraulic servo valve through two independent communicating pipelines; and an electric control throttle valve and an energy accumulator are arranged on the communicating pipeline. By switching the electro-hydraulic servo valve, the electric control throttle valve and the energy accumulator, the suspension can be switched among an active suspension, a semi-active suspension and a passive suspension, and the structure principle is simple and easy to implement. Meanwhile, the invention further discloses a suspension mode switching method applying the suspension system and a vehicle.

    本发明公开了一种具备模式切换的液压悬架系统,包括:执行器,所述执行器包括进液口与出液口;液压供能装置,能输出压力液体;电液伺服阀,包括切断工位与连通工位,所述执行器与液压供能装置通过电液伺服阀连通;连通管路,所述进液口与出液口分别通过两个独立的连通管路与所述电液伺服阀连通;所述连通管路上设有电控节流阀以及蓄能器。本发明可以通过切换电液伺服阀以及电控节流阀以及蓄能器,使得悬架能在主动悬架、半主动悬架以及被动悬架之间进行切换,而且结构原理简单,易于实现。同时,本发明还公开了一种应用上述悬架系统的悬架模式切换方法以及车辆。
