Background

Automobiles are common transportation means in modern daily life, and the engine is a part for mainly driving the automobiles. In the running process of the automobile, the engine, the gearbox and the automobile body frequently vibrate, and serious consequences of danger caused by falling off of automobile parts can be caused along with the serious vibration between the parts. Therefore, in order to avoid vibration of the engine and the gearbox, it is often necessary to provide a speed reducer at the engine position to avoid excessive vibration of the engine and the gearbox, wherein a spring damper and a suspension damper are most commonly used.

When the vehicle engine vibrates, oil in the suspension damper chamber repeatedly flows from one chamber through different apertures into the other. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form damping force to vibration, so that the vibration energy of the automobile is converted into the heat energy of the oil, and then absorbed by the shock absorber and emitted into the atmosphere. The engine suspension shock absorber in the prior art can often cause complicated installation operation and time waste because the shape of the leather cup can not be fixed when parts are installed.
