AI Technical Summary
Technical Problem
Existing shock absorbers require larger dimensions to increase damping force, making it difficult to achieve damping force variation while maintaining a compact design.
Method used
The structure includes an upper guide member, a hollow cylindrical expansion member, and an elastic member. By combining multiple guide passages and guide holes, the fluid flow is regulated to increase the damping force, and the damping force characteristics are adjusted by a damping force adjustment member and a damping force variable valve.
Benefits of technology
It achieves increased damping force while maintaining the compact structure of the shock absorber, improving durability and driving stability, and can adjust the damping force characteristics according to the vehicle application.
