CSC Clutch Disengaging System Sealing Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clutch release systems, particularly those designed as Concentric Slave Cylinders, face issues with inadequate sealing against dirt and water ingress, especially in wet conditions, and require significant installation space, making them unsuitable for all applications.
Innovation Solution
A release system with a torsionally rigid second bearing ring connected to a spring retaining plate that functions as both a spring preload mechanism and a labyrinth seal, eliminating the need for a separate labyrinth seal and reducing installation space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate labyrinth seal is used to seal the release bearing, then sealing reliability is improved, but device complexity and installation space requirements increase
Solution Approach 1:
The spring retaining plate is designed to perform multiple functions simultaneously: it retains the spring means, connects the bearing rings, and provides sealing functionality through its radially inwardly directed flange. This integration eliminates the need for a separate labyrinth seal, reducing device complexity while maintaining sealing reliability
Solution Approach 2:
The spring retaining plate is designed as a multi-functional component that combines spring retention, structural connection, and sealing functions. The flange of the spring retaining plate creates a gap seal that prevents dirt and water ingress while the component maintains its primary functions of spring retention and bearing ring connection
2Reliability
If a separate labyrinth seal is installed to prevent dirt and water ingress, then sealing performance is improved, but installation space requirements increase
Solution Approach 1:
The sealing function is merged into the spring retaining plate structure itself. The flange extending radially inwardly from the spring retaining plate creates an effective gap seal without requiring additional sealing components, thereby reducing the overall installation space while maintaining sealing performance
Solution Approach 2:
The spring retaining plate serves as both a spring retention mechanism and a sealing element. Its flange design creates a gap seal that prevents dirt and water ingress, eliminating the need for separate sealing components and reducing installation space requirements
3Reliability
If multiple separate sealing components are used, then sealing reliability is improved, but assembly effort and manufacturing costs increase
Solution Approach 1:
The sealing function is integrated into the spring retaining plate, which is a necessary component for spring retention and bearing ring connection. This eliminates the need for separate sealing components, reducing assembly effort and manufacturing costs while maintaining sealing reliability
Solution Approach 2:
The spring retaining plate is designed to perform multiple functions including spring retention, structural connection, and sealing. This multi-functionality reduces the total number of components, simplifying manufacturing and assembly processes while ensuring reliable sealing against dirt and water
