Description

Technical Field

[0001] This utility model relates to the field of motorcycle front shock absorbers, and more particularly to an adjustable preload motorcycle front shock absorber. Background Technology

[0002] The front shock absorber is a crucial component of the motorcycle suspension system. Its primary function is to reduce the impact of road imperfections and potholes on the front of the motorcycle, creating a smooth ride. The working principle of a motorcycle front shock absorber involves three key elements: springs, dampers, and air pressure. Springs absorb the energy generated by the motorcycle's vertical movement, dampers control the spring's speed by generating resistance, and air pressure adjusts the shock absorber's stiffness. The design of a motorcycle front shock absorber must meet various requirements, including improving ride comfort, protecting cargo, reducing stress on various parts of the motorcycle body, increasing component lifespan, and enhancing tire grip. These requirements ensure the shock absorber's effectiveness under different driving conditions.

[0003] The installation process of some existing motorcycle front shock absorbers is quite cumbersome, making it inconvenient for users to install them in their daily work and affecting their work efficiency. Therefore, we propose an adjustable preload motorcycle front shock absorber to solve this problem. Utility Model Content

When the preload of the shock absorber needs to be adjusted, the first handwheel 11 is turned, causing the first roller 10 to rotate. Subsequently, the first worm gear 9 drives the first worm wheel 8 to rotate, which causes the screw 7 to rotate. This causes the adjusting block 6 to move vertically, thereby compressing the shock absorber spring 4. Then, the fixing bolt 12 is inserted into the corresponding round hole and tightened to the connecting block, thus completing the preload adjustment of the shock absorber.

[0014] This utility model has a reasonable structural design. Through the cooperation between the connecting rod, the second handwheel, the second worm gear, the second worm, and the insert block, the shock absorber body can be easily fixed to the vehicle. This allows users to quickly install it to the vehicle when needed, further improving the user's work efficiency. Attached Figure Description
