Vehicle Axle Dynamic Damper With Snap-Fit Split Ring Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dynamic dampers for vehicle axles face challenges in quickly and simply installing and locking onto the axle, often requiring conventional clamping rings or straps, which can be time-consuming and inefficient.
Innovation Solution
A dynamic damper design featuring a resilient material with an annular mass and a metallic split ring, where the split ring has locking protrusions that snap-fit into the vehicle axle openings, allowing for quick and secure attachment without the need for additional clamping mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional clamping rings or straps are used to attach the dynamic damper to the vehicle axle, then the attachment is secure and reliable, but the installation process becomes time-consuming and complex
Solution Approach 1:
The attachment mechanism is segmented into multiple functional components: the resilient material provides flexible mounting, the metallic split ring provides structural locking, and the locking protrusions provide secure engagement with the axle openings. This segmentation allows each component to perform its specific function efficiently, achieving rapid installation without compromising reliability
Solution Approach 2:
The metallic split ring is nested within the resilient material, which itself is mounted on the vehicle axle. The locking protrusions extend from the split ring into the axle openings, creating a nested configuration where each element is contained within or engaged by the previous one. This nested structure achieves secure attachment in a single integrated assembly that installs quickly
2Reliability
If conventional clamping rings or straps are used to attach the dynamic damper, then the attachment is secure, but the device structure becomes more complex
Solution Approach 1:
The resilient material, metallic split ring, and locking protrusions are merged into a single integrated attachment system. The split ring is embedded within the resilient material, and both work together as one unified mechanism to attach the damper to the axle. This merging eliminates the need for separate clamping rings or straps, reducing overall structural complexity while maintaining secure attachment
Solution Approach 2:
The metallic split ring serves multiple functions simultaneously: it provides structural support, enables locking through its protrusions, and works with the resilient material to ensure secure attachment. The locking protrusions serve dual purposes by both securing the split ring to the axle and preventing axial movement of the entire damper assembly. This multi-functionality reduces the number of separate components needed

Implementation Method 2
There is a need to dampen any vibrations that might be generated as a result of the high-speed rotation of the vehicle axle
Implementation Method 3

AI summary
A dynamic damper includes a resilient material, an annular mass and a metallic split ring. The resilient material has a central bore formed therethrough dimensioned to receive a vehicle axle. The central bore defines a first inner diameter. The annular mass is surrounded and embedded in the resilient material. The annular mass defines a second inner diameter greater than the first inner diameter. The metallic split ring is embedded within the resilient material along a portion of the surface of the central bore with locking protrusions extending into the central bore. Ends of the locking protrusions define a third inner diameter smaller than the first inner diameter. The locking protrusions is dimensioned to extend into openings in the vehicle axle locking the metallic split ring, the resilient ring and the annular mass to the vehicle axle.
