Torque Transmission Device Balancing Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing torque transmission devices with flywheels and centrifugal pendulum modules struggle to introduce a targeted imbalance without compromising bursting and impact rigidity or geometric requirements, particularly in applications with 3-cylinder internal combustion engines.
Innovation Solution
Incorporating a disk-shaped plate element with balancing recesses that can be connected to the carrier device or rotating part via riveting, screwing, or welding, allowing for both balancing and intentional imbalance adjustment, enhancing the torque transmission device's modular design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If material is removed from the flywheel or centrifugal pendulum module to introduce a targeted imbalance, then the imbalance can be adjusted for specific applications (e.g., 3-cylinder engines), but the bursting and impact rigidity and geometric requirements are jeopardized
Solution Approach 1:
The invention divides the balancing function into a separate, dedicated component (the disk-shaped plate element with balancing recesses) rather than modifying the main structural components (flywheel or centrifugal pendulum module). This segmentation allows the balancing function to be adjusted independently without compromising the structural integrity of the main components.
Solution Approach 2:
The disk-shaped plate element acts as an intermediary component that provides the balancing function. It is connected to either the carrier device or the rotating part, serving as a mediator that introduces the required imbalance without directly modifying the structural components. This intermediary approach allows imbalance adjustment while preserving the bursting and impact rigidity of the main structure.
2Ease of manufacture
If the centrifugal pendulum module is designed as a preassembled module, then assembly is simplified and modular design is achieved, but the ability to introduce targeted imbalance is limited
Solution Approach 1:
The disk-shaped plate element serves multiple functions: it can be connected to either the carrier device or the rotating part, and it provides both balancing and targeted imbalance capabilities. This multi-functionality allows the preassembled modular design to be maintained while adding the versatility to introduce specific imbalances for different applications.
Solution Approach 2:
The invention makes the balancing configuration dynamic by allowing the disk-shaped plate element to be selectively connected to different components (carrier device or rotating part) and by providing multiple balancing recesses that can be selectively used. This dynamic configurability enables the same modular assembly to be adapted for different imbalance requirements.
3Adaptability or versatility
If balancing recesses are formed in the flywheel or centrifugal pendulum module, then imbalance can be introduced, but the structural integrity and geometric requirements are compromised
Solution Approach 1:
The balancing function is segmented into a separate disk-shaped plate element with integrated balancing recesses. This separation ensures that the recesses are formed in a dedicated component designed for this purpose, rather than in the precision structural components (flywheel or centrifugal pendulum module), thereby preserving their geometric requirements and manufacturing precision.
Solution Approach 2:
The disk-shaped plate element is specifically designed with local features (balancing recesses) in areas that do not affect the overall structural integrity. The plate element's local geometry is optimized for the balancing function, while the main structural components maintain their precise geometric requirements for load-bearing and rotational functions.
