The material of automobile shock absorber mainly includes metal and rubber two categories. Metal parts such as springs, shock bars and piston components, usually made of high-strength steel or aluminum alloy, these materials have high strength and durability, can withstand a variety of shocks and vibrations in the car. Rubber is used as the buffer block of the shock absorber, providing good elasticity and wear resistance, effectively reducing body vibration
The working principle of automotive shock absorbers is based on the principle of hydraulic shock absorbers. When there is relative movement between the frame (or body) and the axle under vibration, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly flows from one cavity through different pores into another cavity. At this time, the friction between the hole wall and the oil and the internal friction between the oil molecules form a damping force on the vibration, which converts the vibration energy of the vehicle into the oil heat energy, which is then absorbed by the shock absorber and released to the atmosphere
