In modern vehicle design, the engine is mounted by adopting a suspension support, the suspension can be used for fixing and supporting the power assembly, can bear reciprocating inertia force and moment generated by the rotation and translation mass of the engine in the power assembly, can bear dynamic force acted on the power assembly in the running process of the vehicle, can isolate vibration of a frame or a vehicle body caused by excitation of the engine, and can isolate transmission of the vehicle body vibration to the power assembly caused by uneven road surface and road surface impact on wheels.
The existing engine suspension mainly comprises several forms such as a rubber suspension, an air spring suspension, a hydraulic suspension, a semi-active suspension and an active suspension. For the hydraulic mount widely applied at present, the existing hydraulic mount runner structure generally comprises a leather cup, an upper runner plate and a lower runner plate which are buckled with each other, a decoupling film is arranged in an upper fluid chamber enclosed by the upper runner plate and the lower runner plate, the leather cup is buckled on the lower runner plate and forms a lower fluid chamber with the lower runner plate, and the upper fluid chamber is communicated with the lower fluid chamber. When the hydraulic suspension is excited by low frequency and large amplitude, liquid in the upper liquid chamber and the lower liquid chamber flows back and forth between the upper liquid chamber and the lower liquid chamber through the flow channel, and the vibration is damped by utilizing the resistance force applied to the liquid flowing in the flow channel. When the hydraulic suspension is excited by high frequency and small amplitude, the liquid in the flow channel has too large inertia to flow, and at the moment, the liquid in the upper liquid chamber and the lower liquid chamber directly flap the decoupling film through the damping holes on the upper flow channel plate and the lower flow channel plate, so that the decoupling film and the liquid vibrate at high speed together, the high-frequency dynamic stiffness of the hydraulic suspension is reduced, and the vibration is attenuated.
