What do S and H represent in shock absorbers?

[DiLila]

Shock absorbers generally have two adjustment directions: hard and soft. H stands for hard, and S stands for soft. Below is relevant information about shock absorbers: 1. Function: Shock absorbers (Absorber) are mainly used to suppress the oscillation of the spring after absorbing shocks and the impact from the road surface. When driving on uneven roads, although the shock-absorbing spring can filter out road vibrations, the spring itself still has reciprocating motion, and the shock absorber is used to suppress this spring bounce. If the shock absorber is too soft, the car body will bounce up and down. If the shock absorber is too hard, it will create excessive resistance, hindering the normal operation of the spring. 2. Matching: In the process of modifying the suspension system, hard shock absorbers should be paired with hard springs, and the hardness of the spring is closely related to the weight of the car. Therefore, heavier cars generally use harder shock absorbers. The device connected to the vibration-damping crankshaft is used to counteract the torsional vibration of the crankshaft (i.e., the phenomenon where the crankshaft twists under the impact force of cylinder ignition).
