Shock absorbers function by absorbing vibration energy. During vehicle operation, they convert vibration energy from an uneven road surface, acceleration, or braking into heat energy. Inside the shock absorber, the oil flowing through holes and valves generates heat via friction, thus consuming the vibration energy. Their effect lies in protecting vehicle parts. Shock absorbers mitigate damage to other vehicle components like the frame, body, and wheels from frequent vibration and shock. By regulating the suspension system's movement, they decrease wear and fatigue among components. For instance, for wheel bearings, effective shock absorption lessens the extra load from road impacts, thereby prolonging the bearing's lifespan.
