Common shock absorbers include hydraulic shock absorbers and mechanical shock absorbers. Hydraulic shock absorbers are divided into hydraulic shock absorbers and two-way shock absorbers.
Hydraulic shock absorber: Use the compressibility of liquid and the characteristics of liquid to absorb energy when compressed and dissipate energy when flowing to achieve the purpose of reducing or eliminating vibration.
Two-way shock absorber: In addition to axial compression, it can also convert torsional shock into axial shock, using the principle of hydraulic shock absorption to reduce or eliminate longitudinal shock and torsional shock.
