Multiple Disk Clutch Wall Structure for Reliable Actuating Force Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing dual clutch devices face challenges in maintaining reliable and long-term operation due to deformation of the wall section under load, which compromises the transmission of actuating forces through openings in the multiple disk clutch.
Innovation Solution
The design incorporates a multiple disk clutch with a power transmission device featuring transmission fingers that extend through openings in a wall section, where the wall is stabilized by a first wall section extending in the axial direction, and additional sections that provide structural support and increased installation space, allowing for reliable and efficient force transmission without complex structures or production processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the wall section is used to support the multiple disk carrier and transmit actuating forces through openings, then the structural support function is achieved, but the wall deforms under load which jeopardizes reliable operation
Solution Approach 1:
The wall is divided into a first wall section extending in the axial direction and a second wall section extending in the radial direction. The first wall section is specifically designed to bear the actuating forces transmitted through the openings, while the second wall section provides radial support. This segmentation allows each section to be optimized for its specific function, preventing deformation that would compromise reliability.
Solution Approach 2:
The first wall section extends in the axial direction (perpendicular to the radial direction of the second wall section) to provide an additional dimension of structural support. This axial extension creates a more rigid load path for the actuating forces, reducing deformation in the region where openings are present while maintaining the radial support function of the second wall section.
2Ease of operation
If openings are formed in the wall to transmit actuating forces, then power transmission function is enabled, but the wall structure is weakened leading to deformation
Solution Approach 1:
The wall is segmented into two functional sections: the first wall section that handles the actuating forces transmitted through the openings, and the second wall section that provides radial support. This segmentation allows the openings to be positioned in the first wall section without compromising the overall structural integrity, as the second wall section maintains the radial support function.
Solution Approach 2:
Different sections of the wall are given different structural characteristics: the first wall section extending in the axial direction is optimized for transmitting actuating forces through openings, while the second wall section extending in the radial direction is optimized for providing radial support. This local differentiation allows each region to have the quality needed for its specific function.
