Saddle-ride Vehicle Swing Arm Distance Collar Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In saddle-ride vehicles, supporting a distance collar on a swing arm is challenging due to differences in crankcase shape, making it difficult to maintain a simple configuration.
Innovation Solution
A saddle-ride vehicle design featuring a swing arm with a one-side pivot portion, an other-side pivot portion, and a tubular distance collar, where the pivot shaft is passed through the distance collar, allowing it to be exposed outward between collar members, thus eliminating the need for additional support members like a crankcase.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance collar is supported by the crankcase as in related art, then the support structure is established, but the configuration becomes complex and cannot be adapted to different models with different crankcase shapes
Solution Approach 1:
The patent extracts the distance collar support function from the crankcase, making the distance collar an independent component that is not dependent on the crankcase structure. The distance collar is now supported directly by the swing arm body through integration, eliminating the need for crankcase-based support and enabling adaptation to different models regardless of crankcase shape variations.
Solution Approach 2:
The swing arm body is given multiple functions: it serves as both the structural component of the swing arm and as the support structure for the distance collar. This multi-functional design eliminates the need for separate support mechanisms and allows the same swing arm design to be adapted across different models without requiring crankcase-specific modifications.
2Device complexity
If additional support members like crankcase are used to support the distance collar, then the support function is achieved, but the overall structure becomes more complex and heavier
Solution Approach 1:
The patent merges the distance collar support function with the swing arm body structure. Instead of having separate support members like the crankcase, the distance collar is directly integrated into the swing arm body, reducing the number of components and eliminating the weight of additional support structures while maintaining the required support function.
3Adaptability or versatility
If the distance collar is fully enclosed between collar members, then the support is stable, but the configuration becomes complex and difficult to adapt
Solution Approach 1:
The patent extracts the distance collar from the enclosed support structure formed by separate collar members and crankcase. The distance collar is now directly mounted on the swing arm body with its outer peripheral surface exposed, eliminating the complex enclosed structure while maintaining support stability through the direct integration with the swing arm body.

AI summary
The saddle-ride vehicle includes a tubular distance collar that is disposed between a one-side pivot portion and an other-side pivot portion and through which a pivot shaft is passed, the one-side pivot portion is provided with a tubular one-side collar member through which the pivot shaft is passed, the other-side pivot portion is provided with a tubular other-side collar member through which the pivot shaft is passed, the distance collar is interposed between the one-side collar member and the other-side collar member, and the distance collar is exposed outward between the one-side collar member and the other-side collar member separated from each other to the left and right, in a state where the pivot shaft is passed through the distance collar.
