Motorcycle Wet Clutch Arc Spring Damper Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clutch devices in motorcycles face challenges in achieving adequate vibration isolation with limited installation space, leading to stiff linear compression springs that negatively impact vibration isolation and increase costs.
Innovation Solution
A wet-running clutch device with an outer and inner clutch basket, featuring a damper device that includes at least one arc spring for vibration isolation and rotational irregularity damping, allowing torque transfer between the baskets and utilizing arc springs mounted in both axial and radial directions for effective vibration damping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If linear compression springs are used for vibration isolation in limited installation space, then the springs must be designed to be correspondingly stiff, but this negatively affects vibration isolation
Solution Approach 1:
The patent applies arc springs with curved geometry instead of linear compression springs. The arc-shaped design allows the springs to achieve the necessary stiffness for limited installation space while maintaining vibration isolation capabilities through their curved structure, which provides both mechanical support and damping properties.
Solution Approach 2:
The patent changes the geometric parameters of the spring from linear to arc-shaped configuration. This parameter change enables the spring to function effectively in limited space while preserving vibration isolation performance, as the curved geometry provides both structural rigidity and damping characteristics.
2Quantity of substance
If six comparatively short linear compression springs are used, then installation space is reduced, but vibration isolation is negatively affected
Solution Approach 1:
The patent merges the functions of multiple linear springs into fewer arc springs. The arc-shaped design provides both the mechanical support and vibration isolation functions that previously required multiple separate linear springs, reducing the total number of components while maintaining or improving isolation performance.
3Volume of moving object
If stiff springs are used to fit limited installation space, then space requirements are met, but costs increase
Solution Approach 1:
The arc spring design with curved geometry allows for more efficient use of installation space without requiring excessively stiff or numerous springs. This geometric optimization reduces material requirements and manufacturing complexity, thereby lowering production costs while meeting space constraints.
