[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-4 The utility model provides a technical solution for a motorcycle shock absorber sleeve:

[0019] according to Figure 1-4 As shown, it includes a sleeve 1 and a sleeve column 4. The sleeve 1 is sleeved and connected to the sleeve column 4. A fixing ring 8 is fixedly installed on the inner wall of the sleeve 1. The fixing ring 8 is sleeved and connected to the sleeve column 4. An annular oil storage chamber 10 is opened inside the fixing ring 8. A plurality of roller grooves 11 are equidistantly opened on the inner wall of the fixing ring 8. Balls 12 are rotatably connected inside the plurality of roller grooves 11. One side of the ball 12 is in contact with the surface of the sleeve column 4, and the other side of the ball 12 is connected to the inside of the annular oil storage chamber 10.

[0020] Specifically, by providing a fixing ring 8 on the inner wall of the sleeve 1, and by cooperating with the annular oil storage chamber 10 and the ball 12 opened inside the fixing ring 8, the surface of the sleeve 4 can be lubricated during the extension and retraction of the sleeve 4, thereby effectively reducing the wear between the sleeve 1 and the sleeve 4 and improving the service life of the sleeve 1.

[0021] according to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, an annular oil storage cavity 10 is provided on one side of the top end of the sleeve 1 and is connected to the oil filling groove 9 , and a sealing plug 5 is nested and connected to the top of the oil filling groove 9 .

[0022] A piston 7 is fixedly provided at the bottom of the sleeve 4, and the size of the piston 7 is adapted to the inner diameter of the sleeve 1. Specifically, the lifting and lowering of the sleeve 4 is achieved through the cooperation of the piston 7.
