Segmented Centrifugal Element for Torque Fluctuation Inhibition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing torque fluctuation inhibiting devices face challenges in manufacturing cost and complexity due to the requirement of forming groove portions on single centrifugal elements, which increases production costs and difficulties in setting suitable widths for rollers.
Innovation Solution
A torque fluctuation inhibiting device comprising a first rotor, a second rotor, and a centrifugal element with a cam mechanism, where the centrifugal element is formed by multiple components, allowing for easier configuration and reduced manufacturing costs by separating the engaging and cam portions across different components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If groove portions are formed on each centrifugal element to engage rollers, then the centrifugal element can be configured to inhibit torque fluctuations, but the manufacturing cost and difficulty increase
Solution Approach 1:
The centrifugal element is divided into multiple separate components: a centrifugal element body and a cam mechanism component. This segmentation eliminates the need to form complex groove portions on a single centrifugal element, as the engaging portions are formed on separate components that can be manufactured more easily and assembled together.

AI summary
A torque fluctuation inhibiting device configured to inhibit torque fluctuations is disclosed. The torque fluctuation inhibiting device comprises a first rotor, a second rotor disposed to be rotatable relative to the first rotor, a centrifugal element, and a cam mechanism. The centrifugal element is configured to receive a centrifugal force generated by rotation of the first rotor. The centrifugal element is disposed to be movable with respect to the first rotor. The centrifugal element includes an engaging portion configured to be engage with the first rotor. The centrifugal element is formed by a plurality of components. The cam mechanism is configured to generate a circumferential force in movement of the centrifugal element and the circumferential force reduces relative displacement between the first rotor and the second rotor.
