Under the chassis on the passenger seat side. Shock Absorber Introduction: The shock absorber (Absorber) is used to suppress the oscillation after the spring absorbs shocks and rebounds, as well as impacts from the road surface. It is widely used in automobiles to accelerate the attenuation of vibrations in the frame and body, thereby improving the vehicle's ride comfort. When driving on uneven roads, although the shock-absorbing spring can filter out road vibrations, the spring itself still undergoes reciprocating motion. The shock absorber is designed to suppress this spring bounce. Working Principle: Most shock absorbers used in automotive suspension systems are hydraulic shock absorbers. Their working principle is that when relative motion occurs between the frame (or body) and the axle due to vibration, the piston inside the shock absorber moves up and down, causing the oil in the shock absorber chamber to repeatedly flow from one chamber to another through different orifices.
