Description

Technical Field

[0001] The utility model relates to a shock absorber, in particular to a shock absorber, belonging to the technical field of shock absorbers. Background Art

[0002] Motorcycles generally produce large vibrations during driving, so motorcycles are generally equipped with shock-absorbing outer cylinders to reduce vibrations. The shock absorber is mainly used to suppress the shock when the spring rebounds after absorbing shock and the impact from the road surface. When passing through uneven roads, although the shock-absorbing spring can filter out the vibration of the road surface, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jump.

[0003] A motorcycle shock absorber is disclosed in the Chinese patent application publication specification CN214838089U. The shock absorber provided by the utility model has high dimensional accuracy and shape and position tolerance accuracy, long service life, good flexibility, the ability to adapt to the processing errors of the cylinder and its mounting hole, and can avoid the front shock absorber from losing shock absorption comfort due to jamming, and has good comfort and safety.

[0004] Although the above solution can prevent the shock absorber from losing its shock absorption comfort due to getting stuck, the shock absorber in the above patent is not convenient to adjust according to different driving conditions of the motorcycle. According to different driving needs of the motorcycle, the spring of the shock absorber is pre-loaded and adjusted to adapt to the motorcycle's inability to face changing road conditions; for this reason, we provide a shock absorber to solve the above problems.
