Motorcycle Clutch Spring Layout for Flexible Disc Spring Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The clutch apparatuses in straddled vehicles, such as motorcycles, face challenges in achieving a high degree of flexibility in load setting for the disc spring due to its small size and location relative to the clutch spring, limiting its ability to urge the pressure member effectively.
Innovation Solution
The disc spring is positioned radially outward of the clutch spring, allowing for an increased diameter, enabling it to exert a larger load and enhance flexibility in load setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the disc spring is located inward of the radially outer edge of the clutch spring and is relatively small, then the clutch spring can be housed in the clutch center, but the disc spring cannot urge the pressure member with a large load, resulting in low flexibility in load setting
Solution Approach 1:
The disc spring is repositioned from an inward location (radially inside the clutch spring) to an outward location (radially outside the clutch spring). This dimensional change in radial positioning allows the disc spring to have a larger diameter and consequently exert a larger load on the pressure member, thereby improving flexibility in load setting without interfering with the clutch spring's housing in the clutch center
2Force
If the disc spring is positioned radially outward of the clutch spring, then the disc spring can be increased in diameter to exert a larger load, but the spatial arrangement becomes more complex
Solution Approach 1:
The clutch center is divided into distinct functional zones: an inner region housing the clutch spring for engagement control, and an outer region accommodating the disc spring for load application. This segmentation allows each spring to operate independently in its optimized position, simplifying the overall spatial arrangement while enabling the disc spring to achieve larger diameter and load capacity

Function Achieved in This Case
This configuration enables the clutch apparatus to achieve a higher degree of flexibility in load setting, improving the clutch's operational performance and responsiveness.
Implementation Method 1
a disc spring provided concentrically with the pressure assembly, the disc spring urging the pressure assembly in a first direction
Implementation Method 2
a clutch spring urging the pressure assembly in the first direction
Implementation Method 3
input-side rotary plates to be rotationally driven in response to rotational driving of the input shaft, the clutch center holding output-side rotary plates arranged alternately with the input-side rotary plates

AI summary
A clutch apparatus includes a clutch center, a pressure assembly, a disc spring provided concentrically with the pressure assembly and urging the pressure assembly in a first direction, and clutch springs urging the pressure assembly in the first direction. The clutch center includes spring housing portions housing the clutch springs. An outer edge of the disc spring in a radial direction of an output shaft is located radially outward of the clutch springs.
