Talk about the things that the car owners have changed when they smell the oil from the shock absorber

【Car owner's family car knowledge]The damping provided by the shock absorber is generated by the flow of shock absorber oil inside the shock absorber. When the shock absorber leaks oil, it means the loss of shock absorber oil, which will make the shock absorber lose its original suppression. The ability of the spring to move, causing negative effects such as body dynamic instability. What we want to introduce to you is one of the things that make car owners change their minds in terms of suspension - oil leakage.

Common causes of shock absorber oil leakage:

1,The shock absorber movement is adhered by sediment. When the shock absorber moves back and forth, the sand will scratch the oil seal due to the random movement of the core, resulting in the failure of the sealing performance of the oil seal, and the shock absorber oil seeps out of the oil seal.

2,After the shock absorber is abnormally impacted, the shock absorber movement is bent and deformed, causing the oil seal to have a matching gap, which will also invalidate the sealing performance of the oil seal. This type of situation mainly occurs with MacPherson shocks that are often subjected to forces that are not axially balanced with the shock.

3.Due to incorrect installation and adjustment, the shock absorber is completely stretched during use, so that the piston reaches the top, the impact type self-lubricating bearing is deformed, and the oil seal is damaged and oil leaks.

4.The quality of the oil seal used by the manufacturer to manufacture the shock absorber is not good enough.

5.The smoothness of the coating of the shock absorber movement is not good enough. After being pressurized by the shock oil, the oil leaks from the fine fitting gap.
