How shock absorbers work

Its working principle is that when the body is subjected to relative motion due to vibration, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly flows from one cavity through different holes into another cavity. At this time, the friction between the hole wall and the oil wave and the internal friction between the oil molecules form a damping force on the vibration, so that the vibration energy of the vehicle is converted into the heat energy of the oil, and then absorbed by the shock to the large and medium, mainly The amount of vibration is converted into heat through friction, which plays the role of vibration reduction.
Specifically divided into the following work situations:
.In the compression stroke, but when the vehicle is compressed downward, the damping force of the shock absorber is small, so as to fully exert the elastic effect of the elastic element and ease the impact. At this time, the elastic element plays a major role.
2. During the extension stroke of the suspension, when the vehicle rises, the damping force of the shock absorber should be large, and the vibration should be quickly reduced.
3. When the relative speed between the vehicle body and the tire is too high, the shock absorber is required to automatically increase the fluid flow, so that the damping force is always kept within a certain limit, so as to avoid excessive impact load.
