What is a Car Shock Absorber?

In order to rapidly attenuate the vibration of the frame and the body and improve the ride comfort and comfort of the car, shock absorbers are generally installed in the car suspension system.

1. What is a shock absorber?

The shock absorber is a vulnerable part in the process of using the car. The quality of the adjustable air shocks for cars will directly affect the stability of the car and the life of other parts. Therefore, we should always treat the shock absorber well. The working state of the shock absorber can be checked by the following methods.

2. The use of shock absorbers

A well-working shock absorber wholesale has no abnormal noise, comfort, and normal handling during driving. On the contrary, when the shock absorber is abnormal, the vehicle will show abnormal noise, large shaking, poor comfort, and poor handling stability;

After determining that the shock absorber has a problem or failure, you should first check whether the shock absorber has oil leakage or signs of old oil leakage.

The oil seal washer and the seal washer are broken and damaged, and the oil storage cylinder head nut is loose. It may be that the oil seal and the sealing gasket are damaged and failed, and the new seal should be replaced. If the oil leakage still cannot be eliminated, the shock absorber should be pulled out. If you feel a hairpin or different weights, further check whether the gap between the piston and the cylinder is too large, whether the shock absorber piston connecting rod is bent, and the surface of the piston connecting rod. Whether there are scratches or scratches on the cylinder and cylinder.

If there is no oil leakage from the shock absorber, you should check the shock absorber connecting pin, connecting rod, connecting hole, rubber, bushing, etc. for damage, desoldering, cracking or falling off.

If the above inspections are normal, the shock absorber should be further disassembled to check whether the matching gap between the piston and the cylinder is too large, whether the cylinder is strained, whether the valve seal is good, whether the valve disc and the valve seat fit tightly, and Whether the extension spring of the shock absorber is too soft or broken, repair it by grinding or replacing it according to the situation.
