Through the design of the lower connector 4 and the upper connector 3, the shock absorber 1 can be more conveniently connected with the frame and other components of the motorcycle, while ensuring the stable installation and effective work of the shock absorber spring 20. This connection mode improves the overall rigidity and durability of the shock absorption system.

[0028] As a preferred embodiment of the present application, the shock absorber spring 20 is welded with a mounting ring 21 at both ends, and the two mounting rings 21 are integrally formed with a connecting ring 22 coaxially on the outer wall away from the shock absorber spring 20. The design of the mounting ring 21 and the connecting ring 22 enables the shock absorber spring 20 to be more firmly connected with the movable ring 11 and the end of the piston rod of the shock absorber 1, while facilitating installation and disassembly. This connection mode improves the reliability and stability of the shock absorber spring 20, and reduces the failure caused by loose or failed connection.

This design enables the shock absorbing spring 20 to effectively absorb and alleviate vibrations when the motorcycle is driving on uneven roads, improving the stability of driving and the comfort of riding.

[0036] When it is necessary to adjust the shock absorption performance, it is only necessary to rotate the adjustment nut 13. Due to the threaded connection between the nut and the lead screw 12, the movable ring 11 will slide along the outer wall of the shock absorber 1, thereby changing the pre-tightening force and working stroke of the shock absorbing spring 20. This design enables the driver to make personalized adjustments to the shock absorption performance of the motorcycle according to different road conditions and driving needs.

[0037] In addition, the lower connecting head 4 of the shock absorber 1 is integrally formed with the upper connecting head 3 at the end of the piston rod, so that the shock absorber 1 can be more conveniently connected with the frame and other components of the motorcycle. The mounting ring 21 and the connecting ring 22 welded at both ends of the shock absorbing spring 20 ensure that the shock absorbing spring 20 can be more firmly connected with the shock absorber 1 and the piston rod, and facilitate installation and disassembly.

[0038] The design of the baffle 30 at the bottom of the upper connecting head 3 not only enhances the structural strength of the upper connecting head 3, but also realizes reliable connection between the shock absorbing spring 20 and the piston rod through the threaded connection of the first ring groove 31 and the connecting ring 22. The second ring groove 110 on the outer wall of the movable ring 11 is stably connected with the mounting ring 21 of the shock absorbing spring 20, further improving the stability of the shock absorption system.

[0039] Finally, the four lead screws 12 on the movable ring 11 are arranged in a ring array, which improves the stability and load-bearing capacity of the movable ring 11, ensuring the smoothness and reliability of the spring assembly 2 during adjustment.
