Provide the shock absorber damping is caused by the shock absorber oil shock absorber internal flow, when the leakage phenomenon of shock absorber, means that the shock absorber oil loss, this will make the shock absorber had lost the ability to restrain the spring movement, causing the body dynamic instability and other negative effects. We want to introduce is a shock to owners who dreaded that oil spill.
The common cause of the oil shock absorber:
1, shock absorber by sediment movement on the reciprocating motion of adhesion, shock absorber, sediment core and scratch seal random movement, resulting in the failure of oil seal sealing performance, shock absorber oil from the oil seal leakage.
2, shock absorber under abnormal shock, the bending deformation of suspension movement, which emerged with the seal gap, it will also make the sealing performance of oil seal failure. This kind of situation occurs mainly in McPherson type shock absorber and shock absorber are often not balanced axial force.
3, due to the installation and training is not correct, the shock absorber in the use process appear fully stretched so that the piston top, collision type self-lubricating bearing deformation, so the damage and leakage of oil seal.
The 4 seal quality, manufacturers of shock absorbers when do not pass.
5, shock absorber coating roughness movement does not pass, after the shock absorber oil pressure, oil leakage from the micro clearance.
