Technical characteristics of shock absorbers

When the frame and the axle reciprocate relative to each other, and the piston in the shock absorber also reciprocates in the cylinder, the oil in the shock absorber shell will repeatedly pass through some narrow pores from an inner cavity. Flow into another cavity. At this time, the friction between the hole wall and the oil and the friction within the liquid molecule form a damping force against vibration, which converts the vibration energy of the vehicle body and the frame into heat, which is absorbed by the oil and the shock absorber shell, and then Spread into the atmosphere. The damping force of the shock absorber increases or decreases with the increase or decrease of the relative speed between the frame and the axle (or wheel), and is related to the oil viscosity. The viscosity of the oil used in the shock absorber is required to be as small as possible due to temperature changes; and it has the properties of resistance to vaporization, oxidation, and non-corrosion to various metal and non-metal parts.
