Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, specifically to a shock absorber spring preload adaptive electro-hydraulic adjustment device. Background Technology

[0002] For riding comfort, motorcycles are equipped with shock absorbers. However, the required elasticity of the shock absorber varies depending on the road conditions and the motorcycle model, aiming for optimal comfort. Spring preload, simply put, refers to the amount of compression the spring beforehand, determining whether it is stiff or soft. If the shock absorber is too soft, the motorcycle will bounce up and down; if it is too stiff, it will create excessive resistance, hindering the spring's proper function. Therefore, the rider can adjust the spring preload according to road conditions and their own comfort level. However, the preload of the springs in existing shock absorbers is generally fixed and cannot be adjusted. Based on these issues, we propose a shock absorber spring preload adaptive electro-hydraulic adjustment device. Utility Model Content
