Car Parts Suspension Hydraulic Shock Absorbers OEM84230348 For CHEVROLET EQUINOX GMC TERRAIN 2018-2020

In order to improve the ride comfort of the car, shock absorbers are installed in parallel with the elastic components in the suspension system. In order to attenuate vibration, the shock absorbers used in the suspension system are mostly hydraulic shock absorbers. The working principle is that when there is relative movement between the frame (or body) and the axle under vibration, the piston in the shock absorber moves up and down. The oil in the shock absorber cavity repeatedly flows from one cavity through different pores into another cavity. At this time, the friction between the hole wall and the oil 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 oil heat energy, and then absorbed by the shock absorber to the atmosphere. When the oil channel section and other factors are unchanged, the damping force increases or decreases with the relative motion speed between the frame and the axle (or the wheel), and is related to the oil viscosity.
