Rubber Crawler Ridge Adhesion for Cornering Strain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing rubber crawler designs face issues with strain and peeling of adhesion means during cornering of tracked vehicles due to uneven load distribution, leading to durability concerns.
Innovation Solution
A rubber crawler design featuring a crawler main body with a ridge on its inner or outer surface, where lug and guide projections are adhered using an adhesion means, allowing for reduced strain and improved durability by positioning the adhesion means away from high-stress areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If vulcanization adhesion is performed with an adhesion means being sandwiched between the inner circumferential surface and a guide projection, then the guide projection can be integrated with the crawler main body, but strain occurs in the adhesion means during cornering leading to peeling
Solution Approach 1:
The patent positions the adhesion means in the widthwise direction (radial dimension) rather than only in the circumferential direction. Specifically, the adhesion means extends from the inner circumferential surface toward the guide projection in the radial direction, creating a three-dimensional adhesion structure that distributes strain more effectively and prevents peeling during cornering operations.
Solution Approach 2:
The patent applies different structural characteristics to different regions of the adhesion means. The adhesion means has a first portion adhering to the inner circumferential surface and a second portion extending toward the guide projection, with varying thickness and strain distribution characteristics in different regions to optimize both adhesion strength and resistance to cornering strains.
2Device complexity
If the adhesion means is arranged at the same height as the inner circumferential surface, then the structure is simple, but strain is likely to occur in the adhesion means during cornering
Solution Approach 1:
The patent extends the adhesion means in the radial direction (widthwise dimension) from the inner circumferential surface toward the guide projection. This three-dimensional configuration allows the adhesion means to be positioned at different heights and distances from the inner surface, creating a structure that resists cornering strains while maintaining reasonable manufacturing complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances durability by reducing strain on the adhesion means and improving the adhesion strength, leading to a longer-lasting rubber crawler with reduced fatigue and production costs.
Implementation Method 1
lugs and projections (guides) are respectively subjected to vulcanization molding previously, and are subjected to vulcanization adhesion to be integrated by using an adhering rubber sheet
