Description

Technical Field

[0001] The utility model relates to the technical field of shock absorber oil sealing devices, and more specifically, to a motorcycle shock absorber oil sealing device. Background Art

[0002] The motorcycle shock absorber is a mechanical structure for accelerating the attenuation of the vibration of the frame and body to improve the smoothness and comfort of the motorcycle's ride. It is mainly composed of a shock-absorbing cylinder, a shock-absorbing piston rod, a buffer spring, a piston oil seal and other structural parts. The piston oil seal is installed at the connection between the barrel mouth of the shock-absorbing cylinder and the shock-absorbing piston rod. Its main function is to prevent the buffering and damping oil inside the motorcycle shock absorber from leaking to the outside from the connection between the barrel mouth of the shock-absorbing cylinder and the shock-absorbing piston rod. Therefore, the piston oil seal of the motorcycle shock absorber is also called a piston seal, which is usually made of rubber or silicone. Compared with other metal structural parts of the shock absorber, the piston oil seal made of rubber or silicone is a wearing part. When the piston oil seal is damaged, it needs to be replaced. When replacing the new piston oil seal, an oil seal pressing device is needed to press the new piston oil seal flat into the barrel mouth of the shock-absorbing cylinder.

However, when using local materials to press and assemble the piston oil seals, there is a lack of rigor and the flatness of the oil seal pressing cannot be guaranteed. There is also a risk of damaging the shock absorber cylinder, which has great limitations. Utility Model Content
