Solution Overview
Problem
Existing damper arrangements in drive trains of motor vehicles face challenges in efficiently damping torsional vibrations while optimizing installation space, load capacity, and weight, often requiring a compromise between these parameters.
Innovation Solution
A tuned mass vibration damper is designed with a damper mass and guide components that allow for the transmission of torque through a connection structure, incorporating a spacer or integrally formed connection sections to enhance load capacity and compactness, and featuring a dual-mass flywheel arrangement to simplify torque control and reduce space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional damper arrangements use separate components for guide elements and connection structures, then the design flexibility and ease of manufacture are improved, but the number of parts increases and installation space requirements increase
Solution Approach 1:
The patent combines the first guide element, second guide element, and connecting structure into a single integrated component. This merging reduces the number of separate parts while maintaining the functional capabilities of guiding the damper mass and transmitting torque, thereby reducing installation space and simplifying the overall assembly.
Solution Approach 2:
The integrated component serves multiple functions simultaneously: it acts as a guide element for the damper mass, provides structural connection, and transmits torque. This multi-functionality eliminates the need for separate components, reducing both part count and installation space while maintaining manufacturing feasibility.
2Strength
If the connecting structure is designed as a separate component (spacer), then the load capacity and torque transmission are improved, but the installation space requirements increase
Solution Approach 1:
The connecting structure is merged with the guide elements to form an integrated component that maintains sufficient load capacity and torque transmission capabilities while occupying less installation space. The integration allows for optimized material distribution and structural efficiency.
Solution Approach 2:
The patent optimizes the spatial arrangement and dimensional configuration of the integrated component to achieve efficient torque transmission and load bearing within a compact volume, utilizing three-dimensional space more effectively.
3Reliability
If multiple separate components are used in the damper arrangement, then the functional performance and vibration damping are improved, but the installation space and weight increase
Solution Approach 1:
The patent integrates multiple functional components into a single structure that maintains vibration damping performance while reducing installation space. The integrated design preserves the necessary degrees of freedom for the damper mass to oscillate and dampen vibrations.
Solution Approach 2:
The integrated component performs multiple functions including guiding the damper mass, transmitting torque, and enabling vibration damping, thereby achieving reliable vibration control in a compact configuration that reduces overall installation space and weight.

AI summary
According to one embodiment, a tuned mass damper (110), for example for a drive train of a motor vehicle for damping the oscillation portion of a rotational movement and for transmitting a torque of said rotational movement, comprises at least one damper mass (200) which is designed to oscillate in accordance with the rotational movement in order to damp the oscillation portion of said movement, a first guide component (210) and a second guide component (220) extending substantially parallel to the first guide component (210), the damper mass (200) being displaceably located between the two components. The tuned mass damper also comprises at least one connecting structure (240) which substantially connects the first guide component (210) and the second guide component (220) for conjoint rotation, the first guide component (210), second guide component (220) and the connecting structure (240) being designed in such a way that the torque is transmitted via the connecting structure (240). This allows the compromise between installation space, characteristics, load-bearing capacity and other parameters of a damper assembly (100) to be improved.
