Crawler Bar With Angled Cutting Elements For Mud Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Crawler bars on crawler vehicles tend to lose ground adhesion when used on muddy or slushy surfaces due to clogging with mud, slush, or snow, leading to reduced traction and stability.
Innovation Solution
A crawler bar design featuring a linear bar base body with cutting elements that have non-overlapping cutter portions with angled connecting members, allowing for better engagement with the driving surface and preventing substrate material accumulation, ensuring consistent ground adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the crawler bar uses a base body with spaced cutter portions to prevent tilting, then stability is improved, but spaces between the base body and cutter become clogged with mud, slush and snow, causing loss of ground adhesion
Solution Approach 1:
The cutting element is divided into multiple cutting element portions with cutters spaced apart transversely, creating gaps that prevent substrate material accumulation while maintaining stability through the distributed configuration
Solution Approach 2:
The cutter-connecting members are arranged at different longitudinal positions and angled relative to each other, creating a three-dimensional configuration with non-parallel planes that prevents substrate material from adhering while maintaining structural stability
2Ease of manufacture
If the cutter-connecting members are arranged parallel to each other, then manufacturing is simplified, but substrate material accumulates in the spaces between cutting element portions, reducing ground adhesion
Solution Approach 1:
The cutter-connecting members are arranged asymmetrically with non-parallel orientations, where the main faces of adjacent cutter-connecting members form angles with each other, preventing substrate material accumulation while remaining manufacturable

AI summary
A crawler bar of a crawler track of a crawler vehicle is provided, including a linear bar base body and a cutting element. The cutting element contains a plurality of cutting element portions, each including a cutter-connecting member and a cutter. When installed, the crawler bar engages on a driving surface of the vehicle. The cutter-connecting member protrudes from and extends on the bar base body in a longitudinal extension of the bar base body. A main face of a first cutter-connecting member of a first cutting element portion lies in a plane (H1), a main face of a further cutter-connecting member of a further cutting element portion lies in a plane (H2), and the two planes (H1) and (H2) have a single intersection line (S)with each other.
