Hub Damping Element Insertion via Inclined Ramp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dampable hub discs for clutch devices face difficulties in easily inserting and securing damping elements due to lug formations, which complicate the assembly process.
Innovation Solution
The recess in the hub disc is designed with an obliquely angled side wall forming a ramp that facilitates the insertion of the damping element, allowing for automatic compression and secure fastening, while additional features like projections and angled sections optimize the installation space and damping characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lugs are formed on the side walls of the recess to secure the damping element, then the damping element is well secured, but the damping element becomes very difficult to insert into the receptacle
Solution Approach 1:
The recess is prepared in advance with an inclined side wall section that creates a ramp structure. This preliminary geometric configuration enables the damping element to be guided and compressed automatically during insertion, resolving the contradiction between secure fastening and easy insertion by preparing the receiving structure beforehand.
Solution Approach 2:
The side wall of the recess is designed with varying inclination angles - an inclined section for easy insertion and a perpendicular section for secure fastening. By changing the geometric parameters of the recess structure, the design achieves both easy insertion and reliable securing of the damping element.
2Volume of moving object
If the recess length is reduced in the direction of the recess base, then the installation space is reduced, but the damping element may not be properly accommodated
Solution Approach 1:
The recess design incorporates three-dimensional geometric features including inclined side walls and perpendicular base sections. By utilizing spatial dimensionality effectively, the recess accommodates the damping element reliably while minimizing the overall installation space through optimized volumetric configuration.
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
This design simplifies the assembly of damping elements, reduces the overall installation space, and enhances the damping area and torsional range of the clutch device, making it easier to insert and secure the damping elements while ensuring secure fastening and reduced friction during torsional vibrations.
Implementation Method 1
at least one of the side walls has a first side wall section (16) that runs obliquely in the direction of the recess base (11) and defines a ramp (16) that reduces the recess length (L) in the direction of the recess base (11)
Implementation Method 2
Dampenable hub discs are used in clutch discs to absorb and dampen torsional vibrations in the drive train

AI summary
The disk (2) has a recess (6) with certain recess length (L) for receiving a damping element i.e. helical spring. The recess is radially openly formed in outside and comprises a recess bottom part (11) and two side walls (12, 13). One of the side walls comprises a side wall portion (16) that runs diagonally towards the recess bottom part. The side wall portion defines a ramp that reduces recess length towards the recess bottom part. A projection (22) is utilized to provide a fastener for the damping element. Projection length (A) is adapted to the damping element to be inserted.
