Description

Technical Field

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

[0002] Shock absorbers are used to suppress the shock when the spring rebounds after absorbing shock and the impact from the road. When passing through uneven roads, the shock-absorbing spring can filter the vibration of the road, and the spring itself will have reciprocating motion. The shock absorber is used to suppress this spring jump. Since the shock absorber has a strong shock-absorbing effect, it is also widely used in the front and rear shock-absorbing structures on motorcycles. Motorcycle shock absorbers can reduce the vibration and bumps of the vehicle during driving, and improve riding comfort and stability. It absorbs and disperses the impact force generated during the vehicle's driving, reduces the bumps of the vehicle body and passengers, and makes riding more stable and comfortable.

[0003] The shock absorber of a motorcycle may have some problems during daily use, the most common of which is oil leakage. When the shock absorber is working, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly rubs against the cavity wall. The friction between the cavity wall and the oil and the internal friction between the oil molecules form a damping force on the vibration, so that the vibration energy of the car is converted into oil heat energy, which is then absorbed by the shock absorber and dissipated into the atmosphere. Due to the working principle of the automobile shock absorber, its internal temperature is very high during operation, which can easily cause damage to the oil seal, resulting in oil leakage in the shock absorber. At the same time, dust may enter the shock absorber during use. After the dust enters the interior of the shock absorber, it will also damage the shock absorber's oil seal. Utility Model Content
