Oil-gas composite vibration reduction actuator

The invention discloses an oil-gas composite vibration reduction actuator which has vibration reduction and driving functions and comprises a cylinder body assembly, a piston rod assembly, a valve element assembly, an air chamber assembly, a high-pressure energy storage assembly, an external power oil tank and a control system. When a damping hole of the valve element assembly is opened, the high-pressure energy storage valve is closed, the first electromagnetic valve and the fifth electromagnetic valve are hydraulically controlled to be closed, oil can only flow in the upper oil cavity and the lower oil cavity of the oil cylinder and the air cylinder, and at the moment, the oil-gas composite vibration reduction actuator is equivalent to a common oil-gas spring vibration reducer. When a damping hole of the valve element assembly is closed, the second electromagnetic valve and the high-pressure energy storage valve are closed, at the moment, the oil-gas compound actuator is equivalent to a two-way actuating oi
