Multiple Clutch Encoder Integration for Reliable Speed Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multiple clutches in vehicle drive trains are either complex and bulky or generate unreliable measurement data due to the placement of the transmitter part outside the dual-mass flywheel.
Innovation Solution
The transmitter part is integrated as a non-rotatably connecting element between the first and second clutch components, simplifying the structure and enabling reliable rotation state detection, with a compact design and radial arrangement of the rotational speed and position detection geometry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the sensor element is arranged outside the multiple clutch on the side of the dual-mass flywheel, then the multiple clutch can be simpler in design, but the measurement data becomes unreliable
Solution Approach 1:
The sensor element is integrated directly into the multiple clutch assembly, merging the sensing function with the clutch structure. This eliminates the need for separate external sensor mounting while ensuring reliable measurement by placing the sensor in direct proximity to the rotating components whose speed is being measured.
2Volume of moving object
If the multiple clutch is designed to be compact, then space requirements are reduced, but the design becomes more complex
Solution Approach 1:
The sensor element is nested within the existing structural components of the multiple clutch, specifically utilizing the space within the clutch assembly. This nesting approach allows the sensor to be housed within the clutch structure without increasing the overall volume, while the modular integration keeps the design manageable rather than overly complex.
3Volume of moving object
If the encoder element extends between overlapping connection areas in the axial direction, then the installation space is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The encoder element is pre-positioned and integrated into the clutch assembly during the manufacturing process, with its location predetermined by the overlapping connection areas design. This preliminary integration ensures that the encoder element is correctly positioned before final assembly, reducing the need for high-precision field adjustments while maintaining compact dimensions.
