Track Link Structure With Inclined Plane Connecting Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional track link assemblies for heavy caterpillar vehicles are laborious and time-consuming to maintain due to their integral design, and split-type links suffer from instability issues leading to fastener breakage and assembly issues.
Innovation Solution
A track link structure comprising a first and second mainbody with inclined plane structures and corresponding connecting elements that tilt from the outer to the inner surface, enhancing stability and facilitating easy disassembly, while also incorporating hole slots and through holes for secure fastening without additional auxiliary elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a split-type track link is used to facilitate disassembly, then the ease of repair is improved, but the structural stability deteriorates leading to fastener breakage
Solution Approach 1:
The patent applies curvature by replacing the conventional planar connecting surfaces with arc-shaped connecting surfaces. The first and second connecting portions feature arc surfaces that conform to each other, creating a curved interface between the split track link halves. This curved connection geometry significantly improves structural stability and prevents fastener breakage during operation, while maintaining the ease of disassembly characteristic of split-type links.
2Reliability
If conventional integral track links are used, then the structural stability is improved, but the ease of repair deteriorates due to laborious disassembly
Solution Approach 1:
The patent applies segmentation by dividing the track link into separate components - specifically a first track link portion and a second track link portion that can be independently removed. This segmentation allows the track link to be disassembled for maintenance by removing only the necessary portions, eliminating the need to dismantle the entire conventional integral track link structure.
3Ease of manufacture
If planar connecting surfaces are used in split-type links, then the ease of manufacture is improved, but the structural stability deteriorates causing shaking and fastener failure
Solution Approach 1:
The patent replaces the planar connecting surfaces with arc-shaped connecting surfaces on the first and second connecting portions. These curved surfaces conform to each other when assembled, providing superior structural stability and preventing the shaking and fastener breakage that occurs with flat surfaces, while remaining manufacturable using conventional machining processes.
