What is a Shock Absorber?

[McIsaac]

Shock absorbers are wear-prone components in automobiles. Their performance directly affects the smoothness of the vehicle's ride and the lifespan of other mechanical parts. Therefore, it's essential to maintain shock absorbers in good working condition. Below is relevant information about shock absorbers: 1. Function: The shock absorber (Absorber) is primarily used to dampen oscillations from spring rebound after absorbing shocks and impacts from the road surface. When driving on uneven roads, while suspension springs can filter out road vibrations, the springs themselves still undergo reciprocating motion. The shock absorber serves to suppress this spring oscillation. If the shock absorber is too soft, the vehicle body will bounce excessively; if too hard, it creates excessive resistance, hindering the spring's normal operation. 2. Matching: During suspension system modifications, stiff shock absorbers should be paired with stiff springs. Since spring stiffness is closely related to vehicle weight, heavier vehicles generally use stiffer shock absorbers. The device connected to the vibration-damping crankshaft is used to counteract torsional vibrations of the crankshaft (the phenomenon where the crankshaft twists due to cylinder ignition impacts).
