AI Technical Summary
In existing motorcycle shock absorbers, two springs share a single adjustment device, which is cumbersome to operate and highly complex to adjust. When the two springs are compressed, they are subjected to the same force, making it impossible to dynamically distribute the pressure. This results in insufficient shock absorption efficiency, and long-term vibration can easily cause the springs to become misaligned, leading to poor durability and affecting stability.
It adopts a separate adjustment structure and uses a dual-spring coordinated adjustment method to independently reduce and eliminate the vibration generated during motorcycle operation. The two springs jointly absorb and disperse the vibration energy, and the independent adjustment is achieved by using components such as mounting base, hydraulic piston rod, support bracket, and shock-absorbing telescopic rod.
It improves shock absorption, avoids spatial conflicts inherent in traditional series structures, and enhances the stability and durability of the motorcycle.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of dual-spring coordinated shock absorption equipment, and in particular to a dual-spring coordinated shock absorption device for motorcycle shock absorbers. Background Technology
[0002] Shock absorbers are an important component of motorcycles, filtering out vibrations from the road surface. Their performance directly affects vehicle stability and rider experience.
[0003] Existing motorcycle shock absorbers use a shared adjustment device for both springs, requiring synchronized adjustment. This is cumbersome and complex. Both springs experience the same force when compressed, resulting in a single force state that cannot dynamically distribute pressure according to road conditions. This leads to insufficient shock absorption efficiency, and long-term vibration can cause spring misalignment, resulting in poor durability and affecting stability.
[0004] Existing motorcycle shock absorbers use a shared adjustment mechanism for the two springs, requiring synchronized adjustments that are cumbersome and complex. The two springs experience identical forces during compression, resulting in a single stress state and an inability to dynamically distribute pressure according to road conditions. This leads to insufficient shock absorption efficiency, and prolonged vibration can cause spring misalignment, poor durability, and compromised stability. This solution addresses these issues with a separate adjustment structure, allowing for independent vibration reduction of the two shock-absorbing components. This avoids the spatial conflicts inherent in traditional series structures. Through coordinated adjustment of the two springs, vibrations generated during motorcycle operation can be reduced and eliminated independently. The two springs work together to absorb and disperse vibration energy, improving the shock absorption effect. Utility Model Content

[0013] The beneficial effects of this utility model are:
[0014] Compared to traditional motorcycle shock absorbers, which share an adjustment device for two springs, requiring synchronized adjustments that are cumbersome and complex, and where both springs experience the same force during compression, resulting in a single force state and an inability to dynamically distribute pressure according to road conditions, leading to insufficient shock absorption efficiency, and the risk of spring misalignment due to prolonged vibration, resulting in poor durability and instability, this solution utilizes a separate adjustment structure. This allows for separate vibration reduction by two sets of pressure-reducing components, avoiding the spatial conflicts inherent in traditional series structures. Through the coordinated adjustment of the two springs, vibrations generated during motorcycle operation can be reduced and eliminated independently. The two springs can jointly absorb and disperse vibration energy, improving the shock absorption effect. Attached Figure Description
