Spring shock absorber function: in order to reduce the vibration and impact of the road surface on the vehicle mentioned above, it is necessary for the spring to absorb the energy of vibration and impact. The spring is an energy storage element in the suspension, but it is not enough to store it temporarily. It is also necessary to consume the energy that is unfavorable to the ride comfort and handling stability of the vehicle. It is the shock absorber’s turn, The working principle of the hydraulic shock absorber is that when the frame and the axle move back and forth, and the piston moves back and forth in the cylinder, the oil in the shock absorber shell will repeatedly flow from one inner cavity to another through some narrow pores. At this time, the friction between the hole wall and the oil and the internal friction of the liquid molecules will form a damping force to the vibration, so that the vibration energy of the body and the frame can be converted into heat energy, It is absorbed by the oil and the shock absorber housing, and then dispersed into the atmosphere. Simply put, it converts kinetic energy into heat energy. If the shock absorber operates continuously on the test bench for several minutes, the outer wall of the shock absorber oil storage cylinder will become very hot, even hot.
