Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional centrifugal pendulums have complex structures and assembly processes due to separate components for track formation, leading to increased part counts and potential interference with external components.
Innovation Solution
A centrifugal pendulum design featuring integrally formed protrusions and recesses on support plates, with rollers between tracks allowing the mass to swing and offset torque vibrations, simplifying the structure and assembly while preventing external interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate connecting members are used to form tracks on support plates, then the track formation is achieved, but the number of parts increases and assembly becomes complicated
Solution Approach 1:
The patent merges the track formation function into the support plate itself by integrally forming protrusions that define the tracks. This eliminates the need for separate connecting members, reducing the number of parts and simplifying assembly while maintaining the same functional capability of guiding mass movement along predetermined paths.
2Ease of operation
If masses are fixed to support plates by separate connecting members, then the masses can be restrained along a predetermined path, but the masses protrude from both sides requiring special attention to component arrangement
Solution Approach 1:
The support plate and track-forming protrusions are merged into a single integrated component. This allows the mass to be positioned between the support plate and counterweight with the track formed by the integrally attached protrusion, eliminating the need for separate connecting members and reducing concerns about component interference while maintaining predetermined path restraint.
3Reliability
If conventional centrifugal pendulum structure is used, then torque vibration damping is achieved, but the structure is complex and processing is complicated
Solution Approach 1:
The patent integrates the track-forming function directly into the support plate through integrally formed protrusions, eliminating the need for separate connecting members. This reduces the number of parts, simplifies processing and assembly operations, while maintaining the vibration damping effect through the preserved mass swing mechanism along predetermined paths.

Function Achieved in This Case
The design reduces the number of parts, simplifies assembly, and prevents external interference, resulting in a compact and efficient torque vibration damping mechanism.
Implementation Method 1
A roller is disposed between the first track and the second track in the radial direction, and is able to roll against the first track and the second track
Implementation Method 2
the mass is able to swing relative to the first support plate and the second support plate in a plane perpendicular to the rotation axis and exert a torque on the first support plate and the second support plate. This torque can offset the torque vibration transmitted to the centrifugal pendulum
Implementation Method 3
the mass is able to swing relative to the first support plate and the second support plate in a plane perpendicular to the rotation axis and exert a torque on the first support plate and the second support plate. This torque can offset the torque vibration transmitted to the centrifugal pendulum

AI summary
A centrifugal pendulum includes a first support plate, being able to rotate around a rotation axis; a second support plate, facing the first support plate in the axial direction and fixed to the first support plate. A mass is disposed between the first support plate and the second support plate in the axial direction. The first support plate has a first protrusion extending axially, and the first protrusion is integrally formed with the first support plate and defines a first track. The mass has a through hole extending axially, and the through hole defines a second track. The first protrusion extends into said through hole such that the first track faces the second track in the radial direction. A roller is disposed between the first track and the second track in the radial direction, and is capable of rolling against the first track and the second track, such that the mass is able to move relative to the first and second support plates and apply a torque onto the first and second support plates. The present invention also discloses a torque transmitting device comprising the centrifugal pendulum and a vehicle.
