The role of the shock absorber:
1. Absorb the repeated bounces after various impacts caused by the road surface to accelerate the attenuation of the natural vibration of the spring and provide better driving comfort for the vehicle; 2. Relieve the road The impact of the road quickly absorbs the vibration generated during bumps, so that the vehicle returns to normal driving conditions.
The main function of the shock absorber is to suppress the shock and the impact from the road surface when the spring rebounds after absorbing the shock, so as to improve the driving comfort of the car.
When the frame and the axle reciprocate relative to each other, and the piston in the shock absorber also reciprocates in the cylinder, the oil in the shock absorber housing will repeatedly pass from one cavity through some narrow The pores flow into another cavity. At this time, the friction between the hole wall and the oil and the friction within the liquid molecules form a damping force against the vibration, so that the vibration energy of the body and frame is converted into heat energy, which is absorbed by the oil and the shock absorber shell, and then Disperse into the atmosphere.
When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will reciprocate, and the shock absorber is used to suppress the jump of this 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 normally. In the process of modifying the suspension system, the hard shock absorber should be matched with the hard spring, and the hardness of the spring is closely related to the weight of the car, so heavier cars generally use harder shock absorbers.
