They are the soul partners of the shock absorber. The coil spring is responsible for supporting the weight of the vehicle body. Of course, the shock absorber also plays a certain supporting role. The spring is like the skeleton of the human body, firmly holding the vehicle body. The damper mainly responsible for suppressing the reciprocating motion of the spring. Without springs, the vehicle body would directly press against the wheels. Without shock absorbers, the springs would keep jumping non-stop. Both are indispensable.

The piston cylinder is also called the working cylinder. These two are the core of the shock absorber's movement. The piston rod is like a telescopic rod, with one end connected to the vehicle body and the other end connected to the piston. The piston moves repeatedly in the working cylinder because we have filled the working cylinder with shock absorber special oil, also known as hydraulic oil. There are many tiny valve holes on the piston. When the road surface is bumpy, the piston rod pushes the piston to move inside the cylinder. The hydraulic oil generates resistance through the valve port, which can convert the vibration energy into heat energy and consume it, achieving the effect of shock absorption. Here, it is important to emphasize the piston rod and the working cylinder. They have very high requirements for material precision. Even a millimeter-level error may lead to abnormal noise, oil leakage and the decline of shock absorber performance.

Another one is the regulating valve. These are all relatively core auxiliary accessories. Don't underestimate these small accessories; they directly determine the lifespan and performance of the shock absorber. Especially the hydraulic oil and the oil seal, they will directly affect the lifespan of the shock absorber. Hydraulic oil is the medium for energy transmission and is responsible for transmitting pressure. Dissipating energy and deteriorating oil quality will directly affect the shock absorption effect. The oil seal, a protective guard for the sealing parts, mainly prevents the leakage of hydraulic oil and also stops dust, mud and other substances from the outside from entering the air reduction chamber, playing a protective role. Therefore, the aging of the sealing parts is one of the main reasons for the oil leakage of the shock absorber. What about the regulating valve? It's the piston and bottom valve inside the shock absorber. These valve systems mainly control the flow of hydraulic oil, thereby adjusting the hardness of the shock absorber. By adjusting the force value of the shock absorber, it can adapt to various road conditions because it can adjust the hardness and force value of the shock absorber.
