Pendulum Support for Torque Damping via Single Plate Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pendulum supports for damping devices in motor vehicle torque transmission systems have high manufacturing and assembly complexity, leading to high costs.
Innovation Solution
A method involving cutting a metal sheet to form a crown shape with radially inward lugs, deforming it to create a central recess and planar peripheral collar, and fixing the crown on the collar, utilizing the previously discarded central cutout to reduce material loss and costs, while allowing for rotation and secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional multi-component support structures are used, then mounting flexibility and damping effectiveness are improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent merges the central ring and radially outer ring into a single integrated support structure formed from one plate. The plate contains both the central opening for the inner shaft and the radially outer opening for the outer shaft, eliminating the need for separate components and reducing assembly complexity while maintaining mounting flexibility
Solution Approach 2:
The single plate structure serves multiple functions simultaneously: it provides the central opening for mounting to the input shaft, the radially outer opening for mounting to the output shaft, and the structural framework for supporting pendulums. This multi-functional design reduces the number of parts needed
2Adaptability or versatility
If traditional multi-component support structures are used, then mounting flexibility is improved, but manufacturing cost increases
Solution Approach 1:
The patent combines multiple support components into a single plate that can be manufactured as one piece, reducing the number of manufacturing operations, material waste, and assembly steps required, thereby lowering production costs while maintaining the flexible mounting capabilities
3Adaptability or versatility
If multiple separate components are used, then assembly flexibility is improved, but assembly complexity increases
Solution Approach 1:
The support structure is merged into a single integrated plate that requires fewer assembly operations. The plate is formed with all necessary openings and mounting features during manufacturing, eliminating the need to assemble multiple separate components and reducing assembly complexity

AI summary
The present invention relates to a pendulum support for a damping device of a torque-trasmission device. The invention relates to a method for manufacturing a pendulum support (30) for a damping device (32) of a motor vehicle torque-trasmission device (36). The method comprises the procedures of providing a metal plate (10); cutting a ring (12) that has an annular shape basically in the metal plate; obtaining the part that has a plate (18) shape or an annular loop shape basically of the ring (12); conducting stamping deformation to the plate (18) or the annular loop to have a central concess (24) and a peripheral flange (26), wherein the peripheral flange is plane basically and is offset from the recess (24) in axis direction; and fixing thering (12) on the peripheral flange (26). The present invention also relates to the pendulum support prepared thereby, and the damping device with the pendulum support for the torque-trasmission device.
