Vol Truck Suspension Cabin Shock Absorber Oem 21243048 21862164 7421243060 0021909816 Vibration Damper

Working Principle
To understand the shock absorber, it is very important to understand its working.
First of all, we should know that there are generally two types of shock absorbers one is hydraulic and another one is pneumatic. However, working of both the types of shock absorbers is same.
A shock absorber is generally coupled with a spring, which convert sudden shock waves into oscillatory motion. This oscillatory motion gives us instant relief from the shock but, nobody can have his or her whole ride with these oscillations.
Here is the need of shock absorber arises, it is used to damp those oscillations which are made by the springs.
A general shock absorber contains a perforated piston in a hydraulic chamber. The chamber is totally sealed and hence if piston has to make some movement the only way is to let the hydraulic liquid pass through it.
When a shock comes, piston has to move due to shock. When the piston moves than the hydraulic liquid in the shock absorber has to pass through it.
When the liquid is passed through the very tiny perforated holes in the piston the piston has to do some work against it. That work is done on that expense of the energy generated due to the shock and hence soon the shock absorber loses all the shock energy, which results into no oscillation and smooth ride.

Function
The shock absorber can make the vehicle run smoothly. The shock absorber has the function of buffering vibration. If there is no shock absorber in the suspension, the vehicle will run unsteadily and shake. At present, many automobile shock absorbers are hydraulic shock absorbers. The principle is to fill a cylinder with a small hole and a piston with pressure oil. When the spring vibrates, the oil will be forced to flow through the small hole, thus limiting the effect. The size of the hole diameter determines the size of the restriction. If the diameter of the small hole is small, there is a strong restriction, and the vehicle stability will be high; On the contrary, the car is more comfortable. When designing, the size of the small hole diameter should give consideration to stability and comfort.
