I. Introduction
The shock absorber is mainly used to suppress the shock when the spring bounces after rebound and the impact from the road surface. In the rough road, although the shock absorbing spring can filter the vibration of the road, the spring itself will also reciprocate, and the shock absorber is used to suppress the jump of the spring. If the shock absorber is too soft, the body will jump up and down. If the shock absorber is too hard, it will bring too much resistance and prevent the spring from working properly. In the modification of the suspension system, the hard shock absorbers are matched with the hard springs, and the spring hardness is closely related to the vehicle weight. Therefore, the heavier shock absorbers are generally used for the heavier vehicles. The device connected with the cranking crankshaft is used to counter the torsional vibration of the crankshaft (ie, the phenomenon that the crankshaft is twisted by the impact force of the cylinder ignition).
Second, application
The shock absorber is not used to support the weight of the vehicle body, but it is used to suppress the shock when the spring bounces after rebound and absorb the energy of the road impact. If you drive through a broken car, you can experience the car passing through each pothole, the undulating after-wave bounce, and the shock absorber is used to suppress this bouncing. Without a shock absorber, it is impossible to control the rebound of the spring. When the car encounters a rough road, it will have serious bouncing. When the car is cornered, it will also cause the loss of tire grip and tracking due to the vibration of the spring. The ideal situation is to use a shock absorber to limit spring bounce to about one time.
Third, the type
The shock absorber is divided into two types, hydraulic and pneumatic, from the perspective of the damping material. There is also a variable damping shock absorber. The shock absorbers currently used include: spring dampers, air dampers, oil air dampers, full oil dampers, and rubber shock absorbers.
Fourth, use
It can be used for vibration damping and anti-vibration of various mechanical equipment such as fans, water pumps, generator sets, air compressors, air conditioning main engines, cooling towers, and transformers.
