[0016] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.
[0017] As shown in Figure 1-3, a wear-resistant shock absorber rod includes a pull rod 10, a compression spring 11 and a shock cylinder 12, the pull rod 10 slides in the shock cylinder 12, the compression spring 11 is sleeved on the pull rod 10 and the shock cylinder 12, and connects the pull rod 10 and the shock cylinder 12, an oiling assembly is sleeved on the outer peripheral side of the pull rod 10, the oiling assembly includes a lubricating block 13, a lubricating cavity 14 is opened inside the lubricating block 13, the lubricating cavity 14 is located between the pull rod 10 and the compression spring 11, an outer cover 15 is detachably installed on the outer peripheral side of the lubricating cavity 14, and lubricating oil can be added by removing the outer cover 15, at least two smearing rods 16 are arranged in the lubricating block 13, the smearing rod 16 slides in the lubricating block 13, the end of the smearing rod 16 is rotatably connected to a smearing roller 17, the smearing roller 17 can absorb the lubricating oil, and the lubricating oil is smeared by the smearing roller 17 to reduce the friction of the pull rod 10.
[0018] The smear rod 16 is L-shaped and installed at an angle. The smear rod 16 passes through the lubrication block 13 and extends to the outside. It faces the direction close to the pull rod 10. A lubrication spring 19 is fixed between the smear rod 16 and the inside of the lubrication chamber 14. A counterweight block is provided on one side of the smear roller 17 of the smear rod 16. A guide channel 18 is opened inside the smear rod 16. One end of the guide channel 18 is connected to the lubrication chamber 14, and the other end is connected to the smear roller 17.
[0019] During use, when the shock absorber starts working and the vehicle encounters vibration, the coating rod 16 will move, compressing the lubricating spring 19, driving the coating roller 17 to abut against the outer peripheral side of the pull rod 10, and at this time, the hydraulic oil inside the coating roller 17 will be squeezed onto the pull rod 10. During the movement of the pull rod 10, it will be lubricated by the lubricating oil, which can greatly reduce its friction, reduce the friction damage of the pull rod 10, and extend its service life. When the vibration stops, the coating rod 16 is reset under the action of the lubricating spring 19, and then the coating roller 17 is filled with lubricating oil again through the diversion of the guide channel 18, and will be re-coated during the next vibration, which can greatly extend the service life of the lubricating oil in the lubrication cavity 14.
