Counterforce-Free Pressure Plate Mounting Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting devices for pressure plate assemblies are bulky, making them difficult to handle due to their large design, which complicates the counterforce-free mounting and dismounting process.
Innovation Solution
A mounting device with a release element that displaces axially to impinge spring washer tongues and a hook element that engages behind a coupling lid, allowing the device to rest directly on the lid, reducing size and improving handling by eliminating the need for support on the counterpressure plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mounting device is supported on the counterpressure plate via bridges, then the device can maintain structural stability, but the device size increases making it difficult to handle
Solution Approach 1:
The patent extracts the support function from the counterpressure plate by introducing hook elements that engage with the coupling lid. This removes the dependency on the counterpressure plate for support, allowing the mounting device to be smaller while maintaining stability during operation.
Solution Approach 2:
The patent transitions from radial support (bridges on the counterpressure plate) to axial support (hook elements engaging the coupling lid from the axial direction). This dimensional change allows for a more compact device design while maintaining operational stability.
2Stability of the object's composition
If the mounting device is supported on the counterpressure plate, then structural stability is maintained, but the device design becomes bulky in axial direction
Solution Approach 1:
The coupling lid serves as an intermediary element for support. Instead of directly supporting the mounting device on the counterpressure plate, the hook elements engage the coupling lid, which then transfers the support function. This intermediary approach reduces the axial length while maintaining stability.
3Adaptability or versatility
If bridges are used to support adjustment bodies, then adjustability to different clutch types is enabled, but device complexity increases
Solution Approach 1:
The coupling lid engagement mechanism serves multiple functions: it provides support, enables positioning, and facilitates adaptability to different clutch types. This multi-functional approach reduces the need for separate adjustment mechanisms, thereby simplifying the overall device structure while maintaining versatility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables easier handling and reduces the device's size in both circumferential and axial directions, preventing jamming or slipping, while allowing for both compressed and tensile stress applications through adaptable release elements.
Implementation Method 1
at least one release element, which can be displaced in the axial direction in reference to the pressure plate assembly, which is embodied to impinge spring washer tongues of the pressure plate assembly with an axial force in order to release the normally engaged pressure plate assembly
Implementation Method 2
at least one hook element, which is embodied to engage behind a coupling lid of the pressure plate assembly in order to hold the mounting device in a stationary position, at least in the axial direction in reference to the pressure plate assembly
Implementation Method 3
When the spindle unit is rotated the spindle unit converts the rotary motion into an axial motion, thus moving the release element in the axial direction
