Wet Double Clutch Module Assembly for Safer Transmission Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of wet double clutch mechanisms in motor vehicle transmissions is fragile and prone to damage during transport and assembly, requiring careful handling and quality control, which disrupts manufacturing lines and increases costs.
Innovation Solution
A torque transmission module with a pre-assembled wet double clutch mechanism and clutch housing, protected by a cover, which simplifies assembly and reduces the risk of damage by allowing functional testing before vehicle assembly, and incorporates a low or high pressure oil supply pump supported by the clutch housing to enhance reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the wet double clutch mechanism is assembled separately on the clutch support, then the transmission can be configured with modular components, but the assembly becomes fragile and prone to damage during transport and assembly operations
Solution Approach 1:
The patent merges the wet double clutch mechanism with the clutch support into a single integrated assembly. The clutch mechanism is permanently mounted on the clutch support, eliminating the need for separate handling of these components during transport and assembly operations. This integration resolves the contradiction by maintaining modular configuration benefits while preventing damage through unified structure.
2Adaptability or versatility
If the wet double clutch mechanism is handled separately during assembly, then component flexibility is maintained, but careful handling and quality control checks are required which disrupt production lines
Solution Approach 1:
By integrating the clutch mechanism with the clutch support into a pre-assembled unit, the patent reduces the number of separate assembly operations required on the production line. The integrated assembly can be installed as a single component, eliminating the need for multiple quality control checks and careful handling procedures, thereby improving production efficiency while maintaining adaptability.
