[0035] like Figure 5 As shown, in order to reduce the increase in wear on the surface of the buffer plug rod 31 caused by insufficient lubricant during use, a plurality of arc grooves 341 are provided on the surface of the connecting ring 34, a groove is provided on the connecting ring 34, and a receiving tube 36 is clamped inside the groove, an air delivery groove is provided inside the arc pressure rod 351, the receiving tube 36 is connected with the air pressure ball 35 by means of the air delivery groove, a transmission block 361 is movably inserted inside the receiving tube 36, a sponge board is installed at one end of the transmission block 361, and the sponge board is used to absorb the lubricant, the buffer The movement of the punch rod 31 can compress the reset spring 33 and the fixed spring 41, and can also drive the reset ring 32 to move, so that the arc pressure rod 351 and the air pressure ball 35 can be deformed. After the deformation, the internal air pressure of the air pressure ball 35 changes, which can push the transmission block 361 to move under the action of air pressure, and can push the sponge out along the extension direction of the storage tube 36. A rubber sheet can be clamped at one end of the sponge board, and the rubber sheet is used to press against the storage tube 36 to reduce the volatilization of the lubricant during use.

[0036] like Figure 6 and Figure 7 As shown, in order to reduce the wear of the buffer rod 31 due to the attachment of debris, etc., an inclined groove is provided on the inner side of the transmission ring 4, and a plurality of card blocks 42 are clamped inside the inclined groove. The card blocks 42 are trapezoidal, and cleaning rings 43 are clamped inside the card blocks 42. The cleaning rings 43 are grid-shaped and are concentrically arranged with the transmission ring 4. During the movement of the buffer rod 31, the transmission ring 4 can move on the surface of the buffer rod 31 with the cooperation of the reset spring 33 and the fixed spring 41. When the external blocking sleeve 12 is bumped or aged, dust and debris are easily entered. The cleaning ring 43 inside the transmission ring 4 can clean the surface of the buffer rod 31 during the transmission process, which can play a role in auxiliary cleaning.

[0037] like Figure 8As shown, a support tube 44 is installed inside the cleaning ring 43. The support tube 44 is made of elastic material and has a pair of counterweight shafts 441 installed inside. The counterweight shafts 441 are made of metal and are ring-shaped. Air pressure pads are installed between the counterweight shafts 441. During the movement of the cleaning ring 43, the swing amplitude of the cleaning ring 43 can be increased with the cooperation of the counterweight shafts 441 and the air pressure pads, so that the surface of the buffer rod 31 can be cleaned, reducing the situation where dirt adhesion and cleaning are more difficult.

[0038] Working principle: First, when the shock absorber is running during the bumping process, it can push the buffer rod 31 to move under the action of external force, and play a role of buffering and shock absorption under the action of the fixing spring 41 and the return spring 33. The buffer rod 31 can also play a buffering role under the action of air pressure to reduce the vibration caused by the bump. As the buffer rod 31 moves, the sponge block inserted on the connecting ring 34 can move under the action of external force, and the lubricant is applied to the buffer rod 31 for auxiliary lubrication. The cleaning ring 43 inside the transmission ring 4 can play a role in cleaning dirt and foreign matter, reducing its stuck on the surface of the buffer rod 31. As the shock absorber is in use, the mounting frame 1 can be stuck on the motorcycle, and the position of the clamping ring 24 at the bottom can be adjusted to adapt to different models of motorcycles. The edge operator performs installation limit, which can improve the efficiency of the subsequent installation and maintenance process.

[0039] Then, during the movement of the buffer rod 31, the connecting ring 34 can be pressed against the open end of the sealing tube 3 under the cooperation of the return spring 33 and the fixed spring 41, which can play the role of auxiliary sealing, reduce the entry of dust and debris into the gap between the buffer rod 31 and the sealing tube 3, and ensure the smooth and stable operation of the equipment. The movement of the buffer rod 31 can compress the return spring 33 and the fixed spring 41, and can also drive the return ring 32 to move, so that the arc pressure rod 351 and the air pressure ball 35 are deformed under force. After the deformation, the internal air pressure of the air pressure ball 35 changes, which can push the transmission block 361 to move under the action of air pressure, and can push the sponge out along the extension direction of the storage tube 36. Applying a proper amount of lubricant on the surface of the buffer rod 31 can reduce the wear of the buffer rod 31 during use, reduce the noise generated by the shock absorber during operation, and extend the overall service life.

[0040] Finally, during the movement of the buffer rod 31, the transmission ring 4 can move on the surface of the buffer rod 31 with the cooperation of the reset spring 33 and the fixed spring 41. When the external blocking sleeve 12 is bumped or aged, dust and debris are easily introduced. The cleaning ring 43 inside the transmission ring 4 can clean the surface of the buffer rod 31 during the transmission process, which can play an auxiliary cleaning role and reduce the mixing of debris and impurities inside that affect the operation of the shock absorber.
