[0002] The term shock absorber is a common term in the automotive chassis industry. A car shock absorber is actually a vibration damper. Shock absorbers are not only used in suspension in cars, but also in other locations, such as in the cab, seats, steering wheels, etc. They can also be used as buffers on vehicle bumpers. In the suspension system, elastic elements are vibrated by impact. In order to improve the smoothness of the car's ride, shock absorbers are installed in parallel with the elastic elements in the suspension. In order to attenuate the vibration, the shock absorbers used in the automobile suspension system are mostly hydraulic shock absorbers. Their working principle is that when the frame and the axle are vibrated and there is relative movement, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly flows from one cavity to another through different pores.

[0003] According to a new type of high-pressure resistant automobile shock absorber oil seal disclosed in announcement number CN207848288U, it includes an oil seal body, the oil seal body is provided with a through hole, the through hole is opened in the center position of the oil seal body; the oil seal body is provided with an auxiliary lip, the auxiliary lip is connected to one end of the through hole; the oil seal body is provided with a main lip, the main lip is connected to the other end of the through hole; the oil seal body is provided with a secondary frame, the secondary frame is installed inside the outer periphery of the main lip, the oil seal is mostly in a high-pressure state when in use, such working state is likely to cause the oil seal to deviate, such phenomenon is likely to cause the shock absorber to have oil leakage problems.

[0010] At least one of the above technical solutions adopted in the embodiments of the present application can achieve the following beneficial effects:

[0011] By providing a suction cup, the oil seal can be positioned after installation to prevent the oil seal from being offset due to excessive pressure in the use environment. By providing a metal ring, the oil seal can be supported to prevent the oil seal from being damaged or deformed due to its own low strength. By providing a positioning groove, the metal ring can be limited and protected to prevent the metal ring from falling off due to lack of a limiting structure. BRIEF DESCRIPTION OF THE DRAWINGS
