Damping-force-variable shock absorption assembly

Abstract

The invention discloses a damping-force-variable shock absorption assembly. The damping-force-variable shock absorption assembly comprises a shock absorption spring and a damper assembly. The damper assembly comprises a damping cylinder and a piston assembly. The recovery damping force of the damper assembly can be adjusted, and a recovery damping force adjustment portion is exposed out of a shock absorber. The structure that the recovery damping force can be externally adjusted is adopted, the key performance parameter, namely, the recovery damping force, can be adjusted according to requirements for use environments such as different road conditions when the damping-force-variable shock absorption assembly is used, the dynamic application effect is achieved, the comfort and reliability of a whole vehicle are effectively improved, the adaptability of the whole vehicle to different road conditions is improved, and driving habits of different drivers are met.

Description

technical field [0001] The invention relates to a motor vehicle component, in particular to a shock absorbing assembly with variable damping force. Background technique [0002] Shock absorber is a necessary part of a motor vehicle. The structure affects the handling and comfort of the vehicle. Whether the performance is stable or not is directly related to the safety, reliability, comfort and handling of the vehicle. Existing shock absorbers generally adopt a fixed structure and fixed performance parameters, including shock absorber spring preload, restoration damping force, compression damping force and other key performance parameters of the front shock absorption performance are all fixed values, which are different for the whole vehicle. The adaptability of road conditions is relatively narrow, and it cannot meet the different needs of different road conditions, and the adaptability is poor. Especially for light vehicles such as motorcycles, the scope of application is...

AI Technical Summary

Problems solved by technology

Existing shock absorbers generally adopt a fixed structure and fixed performance parameters, including shock absorber spring preload, restoration damping force, compression damping force and other key performance parameters of the front shock absorption performance are all fixed values, which are different for the whole vehicle. The adaptability of road conditions is relatively narrow, and it cannot meet the different needs of different road conditions, and the adaptability is poor

Especially for light vehicles such as motorcycles, the scope of application is relatively wide. Only using a standardized shock absorber structure will cause motorcycles using a uniform standard shock absorber to be unable to adapt to different use environments, and the restoration of the damping force. It is the main factor that leads to the incompatibility between comfort and reliability
