When the frame and the axle reciprocate relative motion, and the piston in the shock absorber also reciprocate motion in the cylinder, the oil in the shock absorber housing will flow into another cavity from one cavity through some narrow pores repeatedly. At this point, the friction between the hole wall and the oil and the friction within the liquid molecules will form a damping force to the vibration, so that the vibration energy of the body and the frame is converted into heat energy, which is absorbed by the oil and the shock absorber shell, and then dispersed to the atmosphere. The size of the shock absorber damping force depends on the car frame and car bridge (or wheel) relative speed increase or decrease, and with the oil viscosity. It is required that the viscosity of oil used in shock absorber should be affected as little as possible by temperature change. It has the properties of anti-vaporization, anti-oxidation and no corrosion to various metal and non-metal parts.
