Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle shock absorption, in particular to a novel electric vehicle shock absorber. Background Art

[0002] It is well known that in order to quickly attenuate the vibration of the frame and the body and improve the smoothness and comfort of electric vehicles, shock absorbers are generally installed on the suspension system of electric vehicles. Shock absorbers are vulnerable parts during the use of electric vehicles. Their working conditions and the quality of their work will directly affect the stability of the electric vehicle and the life of other parts. In order to achieve long-term riding comfort, the shock absorber also needs to be in good working condition for a long time. The shock absorber of the motor vehicle is mainly used to suppress the shock when the spring rebounds after absorbing shock and the impact from the road surface.

[0003] However, although some electric vehicle shock absorbers can be installed with springs to alleviate the hard vibration impact force, most of them are not convenient to adjust the spring elastic force according to actual needs, and cannot balance the jumping amplitude and buffering force. For example, when the spring elastic force is too small and soft, it will cause the up and down jumping amplitude to be too large, affecting normal work. If the spring elastic force is directly too large and too hard, it will not have the effect of effectively buffering and reducing the vibration impact force, and cannot meet the use requirements. For this reason, we propose a new electric vehicle shock absorber to solve the above problems. Utility Model Content
