Torque Transmission Assembly Radial Space Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current torque transmission assemblies in motor vehicles, particularly those with double wet clutch mechanisms, face limitations in radial space utilization and torque transmission capacity, which affect performance and efficiency.
Innovation Solution
The design integrates a torque transmission assembly with a cover and clutch housing that includes a device for oil distribution, where the cover has a first bearing surface directly supporting the combustion engine casing, allowing for increased radial dimensioning of the double wet clutch mechanism and improved performance by freeing up radial space and grouping functional assembly surfaces on a single support surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the clutch housing is received in the clutch bell, then radial space is occupied, but the torque transmission capacity is limited
Solution Approach 1:
The clutch housing is extracted from the clutch bell, removing it from the radial space constraint. This allows the clutch housing to be positioned elsewhere, freeing up radial space within the clutch bell for the wet dual-clutch mechanism while maintaining the torque transmission function through the cover's bearing surface on the engine housing.
Solution Approach 2:
The mounting interface is moved from a radial arrangement (clutch housing received in clutch bell) to an axial arrangement (cover bearing surface on engine housing). This dimensional change allows the clutch housing to be positioned axially rather than radially, freeing up radial space for the clutch mechanism while maintaining structural support.
2Ease of operation
If multiple mounting surfaces are used, then positioning flexibility is improved, but assembly complexity increases
Solution Approach 1:
Multiple mounting functions (axial positioning, radial support, torque transmission) are merged into a single bearing surface on the cover that contacts the engine housing. This consolidation simplifies the assembly process by reducing the number of separate mounting operations while maintaining all necessary positioning and support functions.
Solution Approach 2:
The cover's bearing surface serves multiple functions simultaneously: it provides axial positioning for the torque transmission module, supports the clutch housing, and interfaces with the engine housing for torque transmission. This multi-functionality reduces the need for separate mounting features and simplifies the overall assembly.
