To provide a compact and lightweight hydraulic control device in an active suspension that does not require a hydraulic pump and a complex tubular hydraulic piping.SOLUTION: An active suspension device for vehicle that controls the vehicle height or cushioning force, includes: a coupling cover that separates an accumulator and connects a shock absorber and the actuator; an accumulator communication pipe that connects the accumulator to a solenoid valve; a shock absorber communication pipe that connects the shock absorber to the solenoid valve in both forward and reverse directions via a check valve; an actuator communication pipe that connects the actuator to the solenoid valve; and the solenoid valve that controls opening/closing of each communication pipe. The active suspension device for vehicle controls the solenoid valve to control the vehicle height or cushioning force of each axle, and forms a valve section of the solenoid valve inside the coupling cover.SELECTED DRAWING: Figure 1

    【課題】油圧ポンプと複雑な管状の油圧配管が不要なアクティブサスペンションにおいて、小型で軽量な油圧制御装置を提供する。【解決手段】車高または緩衝力を制御するアクティブサスペンションにおいて、アキュムレータを分離し、ショックアブソーバとアクチュエータを連結する連結カバと、アキュムレータと電磁弁に連通するアキュムレータ連通管と、前記ショックアブソーバと前記電磁弁に逆止弁を介して順方向と逆方向に連通するショックアブソーバ連通管と、前記アクチュエータと電磁弁に連通するアクチュエータ連通管と、各連通管を開閉制御する電磁弁とで構成し、前記電磁弁を制御して、前記各車軸の車高または緩衝力を制御し、前記電磁弁の弁部を前記連結カバの内部に形成する車両用アクティブサスペンション装置。【選択図】図1
