Description

Technical Field

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

[0002] Shock absorbers are used to suppress the vibration caused by the rebound of the spring after shock absorption and the impact from the road surface. They are widely used in automobiles to accelerate the attenuation of frame and body vibrations to improve the driving smoothness of the car. When passing through uneven roads, although the shock-absorbing spring can filter out the vibration of the road, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jumping and returning motion.

[0003] After searching, a Chinese patent with publication number CN210565950U discloses a split shock absorber, which includes a cylinder: by arranging a buffer block and a buffer ring, when the vehicle body is bumpy due to rough roads during operation, the vehicle body can be well buffered, thereby improving the user's body sensation; by arranging a dust cover, sand, dust and other materials can be prevented from entering the shock absorber, thereby extending the service life of the shock absorber.

[0004] Although the above solution can prevent sand, dust and other substances from entering the shock absorber, the split shock absorber in the above patent does not have the function of adjusting the relaxation effect of the shock absorber according to actual installation needs. The operating intensity of the traditional shock absorber is fixed and the spring length cannot be adjusted. For this reason, we provide a split shock absorber to solve the above problems.
