AI Technical Summary
Technical Problem
In the existing motorcycle rear shock absorbers, the friction between the piston rod and the shock absorber cylinder affects the response speed of the shock absorber.
Method used
A low-friction shock absorber is designed. By setting a lubricating seat and annular lubricating chute on the shock absorbing cylinder, and equipped with a grease device, grease is injected into the lubricating passage, and the grease enters the annular lubricating chute under pressure to reduce the friction between the shock absorbing rod body and the shock absorbing cylinder.
Benefits of technology
Effectively reduce friction in the shock absorber, improve the response speed of the shock absorber, and enable it to deal with vibration and shock faster.

Abstract
The invention provides a low-friction shock absorber which comprises a shock absorption cylinder, a shock absorption rod slidably arranged at the upper end of the shock absorption cylinder and a shock absorption piston fixedly arranged at the lower end of the shock absorption rod, a lubricating seat is arranged at the upper end of the shock absorption cylinder, a connecting hole is formed in the center of the lubricating seat in a penetrating mode, and the shock absorption rod is slidably arranged on the inner side of the connecting hole. An annular lubricating groove is formed in the inner side of the connecting hole, a lubricating channel is formed in the upper end of the lubricating base, a grease injection device is detachably arranged at the upper end of the lubricating base, and a grease outlet hole of the grease injection device communicates with an opening in the upper end of the lubricating channel. During use, lubricating grease can be injected into the lubricating channel through the grease injection device, and then the lubricating grease in the lubricating channel can enter the annular lubricating groove under the action of pressure. When the damping rod body slides on the inner side of the connecting hole, the outer wall of the damping rod body can be coated with the lubricating grease located in the annular lubricating groove, so that friction between the damping rod body and the damping cylinder body is reduced, and the shock absorber has the advantage of being higher in response speed.
