Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional torsional oscillation damping devices for motor vehicle transmission systems face manufacturing complexity and mechanical strength issues due to the large number of windows required for pendular bodies, leading to increased complexity and reduced mechanical integrity.
Innovation Solution
A torsional oscillation damping device with a support having a reduced number of windows, where a single window is shared by both the connecting member and the rolling member, allowing for improved mechanical strength and simplified manufacturing by reducing the number of windows needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If separate windows are provided for each rolling member and connecting member in the support, then the mechanical strength and structural integrity of the support are maintained, but the manufacturing complexity increases and the number of windows becomes large
Solution Approach 1:
The patent combines the functions of separate windows for rolling members and connecting members into a single integrated window structure. The support now has windows that simultaneously accommodate both the rolling member and the connecting member, reducing the total number of windows while maintaining structural integrity and mechanical strength.
Solution Approach 2:
The windows in the support are designed to serve multiple functions: they guide the rolling members, accommodate the connecting members, and maintain the structural integrity of the support. This multi-functional design eliminates the need for separate dedicated windows for each component, simplifying the overall structure.
2Strength
If multiple separate connecting members are provided for pendulum masses, then the mechanical strength between pendulum masses is ensured, but the number of windows required in the support increases
Solution Approach 1:
The patent integrates the accommodation of multiple connecting members into a single window structure. Instead of providing separate windows for each connecting member, the design allows multiple connecting members to be received within shared windows, reducing manufacturing complexity while maintaining the strength requirements between pendulum masses.
3Ease of operation
If a large number of windows are formed in the support, then the rolling members and connecting members can be properly positioned, but the mechanical strength of the support is degraded
Solution Approach 1:
The patent merges multiple positioning functions into fewer, more strategically placed windows. By combining the positioning of rolling members and connecting members into shared windows, the support structure retains more material continuity, thereby maintaining mechanical strength while still achieving proper component positioning.
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 enhances the mechanical strength and simplifies the manufacturing process of the damping device while maintaining effective filtration of torsional oscillations, reducing noise and wear by allowing the connecting member to abut against the window edges, thereby guiding the movement of pendular bodies and preventing radial fall.
Implementation Method 1
at least one rolling member cooperating with a first rolling track secured to the first pendulum mass, a second rolling track secured to the second pendulum mass, and a third rolling track secured to the support, so as to guide the movement of the pendulum body relative to support

Implementation Method 3
at least one pendulum body comprising: a first and a second pendulum mass spaced axially with respect to each other and movable with respect to the support
