Shock absorber (Absorber), is used to suppress the shock after the spring shock shocks and the impact from the road. Widely used in automobiles, in order to accelerate the vibration of the frame and body vibration to improve the ride comfort of the car.
After the uneven road, although the shock-absorbing spring can filter the vibration of the road, but the spring itself will have reciprocating motion, and shock absorber is used to suppress this spring jump. Shock absorber is too soft, the body will jump up and down, the shock absorber is too hard will bring too much resistance, hinder the spring work properly. In the modification process of the suspension system, the hard shock absorbers are to be matched with the hard springs, and the hardness of the springs is closely related to the weight of the cars, so the heavier cars generally use hard shock absorbers. And the shock crankshaft connected to the device, used to counter the crankshaft torsional vibration (that is, the crankshaft by the impact of the cylinder and the impact of the phenomenon of twisting).
