Description

Technical Field

[0001] The invention belongs to the technical field of shock absorbers, and in particular relates to a shock absorber with an upright structure and displacement and inversion. Background Art

[0002] The shock absorber is not used to support the weight of the car body but to suppress the vibration when the spring rebounds after absorbing shock and absorb the energy of road impact. If you have driven a car with a broken shock absorber, you can feel the bounce of the car after each pothole and ups and downs, and the shock absorber is used to suppress such bounce. Without shock absorbers, the rebound of the spring cannot be controlled. The car will have severe bounce when encountering rugged roads. The up and down vibration of the spring will also cause the loss of tire grip and tracking when cornering. The ideal situation is to use shock absorbers to limit the spring bounce to once.

[0003] Shock absorbers are used to suppress the vibration caused by the rebound of the spring after absorbing shock and the impact from the road surface. However, the existing shock absorbers still have some shortcomings. First, there are few buffer devices on the existing shock absorbers, and the buffering effect is a bit poor; secondly, the needs in different situations are also different, which requires adjusting the shock absorption effect, but most of the existing shock absorbers cannot be adjusted; finally, the existing shock absorbers may have good support and poor comfort when absorbing shock, or good comfort and poor support, and there are always some unsatisfactory aspects.
