The invention discloses a composite suspension actuator and a control method thereof.The composite suspension actuator comprises an actuator body and an actuator control system, and the actuator body comprises a lower working cylinder, an upper working cylinder, a ball screw structure, a first spring, a gearbox and a damper; the gearbox comprises a transmission shaft, a transmission gear, a one-way bearing, a gear ring, a sleeve, a magnet exciting coil, a motor and a generator, and the damper comprises an oil cylinder and a rotating mechanism. The actuator control system includes an electrical energy reserve circuit, a sensor, and a controller. The invention further discloses a control method of the composite suspension actuator. A suspension can be controlled to be switched in different modes. According to the invention, good vibration reduction can be realized, energy recovery can be carried out when the suspension is in active control, and the situation of single or simultaneous failure of the generator and the motor can be handled by switching different working modes.

    本发明公开了一种复合悬架作动器及其控制方法,所述复合悬架作动器包括作动器本体和作动器控制系统,所述作动器本体包括下工作缸、上工作缸、滚珠丝杆结构、第一弹簧、齿轮箱和阻尼器,所述齿轮箱包括传动轴、传动齿轮、单向轴承、齿圈、套筒、励磁线圈、电动机和发电机,所述阻尼器包括油缸和旋转机构。所述作动器控制系统包括电能储备电路、传感器和控制器。本发明还公开了一种复合悬架作动器的控制方法,可以控制悬架进行不同模式的切换。本发明不仅能实现很好的减振,而且可以在悬架处于主动控制时进行能量回收,还能通过切换不同工作模式来应对发电机和电动机单个或同时失效的情况。
