The invention discloses a composite energy feedback type vehicle semi-active suspension actuator which comprises a magneto-rheological damping device body, a linear energy feedback mechanism, a rotaryenergy feedback mechanism, an energy recovery circuit, a sensor system and a controller. The linear energy feedback mechanism is installed above a piston rod, and energy recovery is achieved throughvertical movement of the piston rod. The rotary energy feedback mechanism is installed below a piston cylinder, a prefabricated meshing gear is driven to rotate through vertical movement of a rack onan upper cylinder body, and therefore, an energy feedback motor rotates to recover energy. The recovered energy is collected into a vehicle-mounted storage battery by the energy recovery circuit in the form of electric energy. The invention further discloses a control method of the composite energy feedback type vehicle semi-active suspension actuator, and the most appropriate damping is applied according to different working conditions so as to achieve the purpose of energy saving. The actuator is good in shock absorption effect, low in energy consumption and high in energy recovery efficiency.

    本发明公开了一种复合式馈能型车辆半主动悬架作动器,包括磁流变减振装置本体、直线馈能机构、旋转馈能机构、能量回收电路、传感器系统、控制器。直线馈能机构安装在活塞杆的上方,通过活塞杆的上下运动来实现能量回收;旋转馈能机构安装在活塞缸的下方,通过上缸体上的齿条的上下运动来带动预制啮合齿轮转动,从而使馈能电机旋转进而回收能量。回收的能量以电能的形式由能量回收电路收集到车载蓄电池中。本发明还公开了一种复合式馈能型车辆半主动悬架作动器的控制方法,根据不同的工况应用最合适的阻尼,以达到节能的目的。本发明减振效果好,耗能低,能量回收效率高。
