Description

Technical Field

[0001] The utility model belongs to the technical field of shock absorbers and relates to a manually adjustable rear shock absorber for an electric vehicle. Background Art

[0002] The shock absorber is mainly used to suppress the shock caused by the rebound of the spring after absorbing the shock and the impact from the road surface. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jumping. If the shock absorber is too soft, the car body will jump up and down. If the shock absorber is too hard, it will bring too much resistance and hinder the normal operation of the spring. The existing adjustable rear shock absorber of electric vehicles needs to be adjusted before installation or after long-term use to achieve the best working efficiency of the shock absorber, but the conventional adjustable rear shock absorber of electric vehicles needs to be adjusted by a special wrench. It is troublesome for users to adjust by themselves, and it is greatly restricted and inconvenient to adjust. Therefore, a conical adjustable rear shock absorber is proposed to address the above problems. Utility Model Content
