[0029] Specifically, one end of the inner tube 4 is inserted into the inside of the outer tube 5, and the inner tube 4 and the outer tube 5 are elastically connected through the damping spring 6, when the front wheel of motorcycle is vibrated, the inner tube 4 will move in the inside of the outer tube 5, at this time, the damping spring 6 will be extruded and produce elastic force, buffer vibration, achieve the effect of shock absorption. One end of the connecting shaft 7 is screwed with the internal thread 9 on the inner wall of the outer tube 5 through the thread protrusion 10, which facilitates the installation and disassembly between the connecting shaft 7 and the outer tube 5, and also increases the connection stability between the connecting shaft 7 and the outer tube 5. The paint coating 11 can increase the corrosion resistance of the outer tube 5, the aluminium oxide layer 12 can increase the adhesion between the paint coating 11 and the outer tube 5, and further increase the corrosion resistance of the outer tube 5, the polytetrafluoroethylene layer 13 has excellent corrosion resistance, high temperature resistance and low temperature resistance, which can increase the weather resistance of the outer tube 5, and the stainless steel layer 14 can increase the strength of the outer tube 5, and further increase the corrosion resistance of the outer tube 5.

[0030] Further, the inner cylinder 4 is fixedly connected to one end of the fixed disc 3, the outer cylinder 5 is movably connected to the outside of the inner cylinder 4, the size of the outer cylinder 5 is larger than that of the inner cylinder 4, the damping spring 6 is fixedly connected between the fixed disc 3 and the outer cylinder 5, and the damping spring 6 is sleeved on the outside of the inner cylinder 4. Such a structure design can effectively absorb and disperse the vibration energy through the elastic effect of the damping spring 6 when the motorcycle encounters a bumpy road during driving, thereby ensuring the stability and comfort of riding. At the same time, since the outer cylinder 5 is movably connected to the outside of the inner cylinder 4 and has a larger size than the inner cylinder 4, such a spatial layout not only provides sufficient expansion space for the damping spring 6, but also enhances the structural strength and stability of the entire shock absorber.

[0031] Further, the inner thread 9 is formed on the inner wall of the outer cylinder 5, the threaded protrusion 10 is integrally connected to one end of the connecting shaft 7, the inner thread 9 is threadedly connected with the threaded protrusion 10, the connecting shaft 7 is threadedly connected to one end of the outer cylinder 5 through the threaded protrusion 10, and the center of the connecting shaft 7 is circular.

When the motorcycle front wheel shock absorber is used for a long time.

[0032] Specifically, if a component is worn or damaged, the user only needs to unscrew the connecting shaft 7 to easily replace the damaged component without the need to replace the entire shock absorber, thereby greatly reducing the maintenance cost and difficulty. At the same time, the threaded connection between the inner thread 9 and the threaded protrusion 10 also has good sealing performance, which can effectively prevent moisture, dust and other impurities from entering the shock absorber, thereby further prolonging the service life of the shock absorber.

[0033] Further, the piston pad 8 is fixedly connected to one end of the fixed disc 3, the piston pad 8 is slidably connected to the inside of the outer cylinder 5, and the paint coating 11 is fixedly connected to the outer layer of the outer cylinder 5. The paint coating 11 can effectively prevent the outer cylinder 5 from being corroded and worn, thereby improving the overall durability of the shock absorber. At the same time, the paint coating 11 also has a certain aesthetic effect, which can improve the appearance quality of the shock absorber. In addition, the fixed connection between the piston pad 8 and the fixed disc 3 ensures the stability of the piston pad 8 during the working process of the shock absorber, so that the shock absorber can better play the shock-absorbing effect.

[0034] Further, the aluminum oxide layer 12 is fixedly connected between the paint coating layer 11 and the polytetrafluoroethylene layer 13, the stainless steel layer 14 is fixedly connected at the bottom of the polytetrafluoroethylene layer 13, and the polytetrafluoroethylene layer 13 is fixedly connected at one side of the aluminum oxide layer 12. The combination design of the aluminum oxide layer 12 and the polytetrafluoroethylene layer 13 not only enhances the corrosion resistance of the outer cylinder 5, but also improves the wear resistance. The aluminum oxide layer 12 as an intermediate layer has good hardness and wear resistance, which can effectively resist the corrosion of the external environment. The polytetrafluoroethylene layer 13 has excellent corrosion resistance and self-lubricating property, which can further protect the outer cylinder 5 from corrosion and reduce friction with external objects. At the same time, the stainless steel layer 14 as the bottom layer provides additional strength and corrosion resistance, ensuring the stability and durability of the shock absorber in various harsh environments. This multi-layer structure design makes the shock absorber have better overall performance and can better adapt to various complex use environments.

[0035] Working principle and use process: When the motorcycle runs on uneven road surface, the front wheel will be impacted by the force from the road, at this time the shock absorber main body 1 starts to work. The installation shaft 2 as the connecting part of the shock absorber and external parts can bear and transmit these impact forces. The triangular shape design of the shock absorber main body 1 not only increases its structural strength, but also helps to improve the damping effect. The fixed disc 3 plays a role in stabilizing the shock absorber main body 1 and the inner cylinder 4 through the connection of its two ends.

[0036] The relative movement between the inner cylinder 4 and the outer cylinder 5, as well as the elastic deformation of the damping spring 6, together absorb most of the impact force and convert it into heat energy to dissipate. The movable connection design on the outside of the inner cylinder 4 allows the outer cylinder 5 to move freely within a certain range, thereby further improving the damping effect. The size of the outer cylinder 5 is larger than that of the inner cylinder 4, which provides sufficient space for the elastic deformation of the damping spring 6.

[0037] The connecting shaft 7 is threadedly connected with the internal thread 9 of the outer cylinder 5 through the threaded protrusion 10, which not only is firm and reliable, but also is convenient for disassembly and maintenance. The piston pad 8 is slidably connected inside the outer cylinder 5, which plays a role in sealing and guiding, preventing the leakage of oil inside the shock absorber.

[0038] The paint coating layer 11 not only looks beautiful, but also can play a role in rust prevention and corrosion resistance. The superposition design of the aluminum oxide layer 12, the polytetrafluoroethylene layer 13 and the stainless steel layer 14 further improves the corrosion resistance and service life of the shock absorber. The selection of these materials and the structure design together constitute the core advantage of the corrosion-resistant motorcycle front wheel shock absorber of the utility model.
