Tire Chain Web Link With Lateral Indentations For Wear Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tire protection chains face high wear and bending loads, particularly in harsh conditions, leading to reduced service life and increased risk of breakage due to inadequate wear distribution and stability.
Innovation Solution
The web link design features longitudinal webs in depressions between wear webs for enhanced stability and grip, with lateral indentations that become effective early in wear, forming additional gripping edges and reducing bending loads on ring links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If lateral indentations are provided in known web links, then grip is improved, but the indentations only become effective when the central wear ridge is almost completely worn down, reducing service life
Solution Approach 1:
The lateral indentations are positioned and dimensioned to become effective earlier in the wear process. The indentations extend over the height of the outer sides of the protruding wear land sections, so that when the central wear land wears down to a certain extent, the upper side enters the area of the lateral indentations, forming additional gripping edges before the central wear ridge is completely worn down.
Solution Approach 2:
The web link structure is modified with lateral indentations that have specific dimensional characteristics - they extend over the height of the outer sides of the protruding wear land sections and are positioned at a distance from the end face of the wearing ribs. This creates localized gripping features that engage at different stages of wear, optimizing both initial grip and sustained service life.
2Weight of moving object
If bar links are relatively narrow to reduce material usage, then weight is reduced, but the risk of tipping over increases, exerting high bending force on ring links
Solution Approach 1:
The web link structure incorporates protruding wear land sections that extend beyond the side faces of the web member, creating an increased bearing width in the lateral dimension. This dimensional extension provides additional support against tipping without significantly increasing the overall weight of the bar link.
Solution Approach 2:
The web link has non-uniform cross-section with protruding wear land sections that create localized increased bearing width. This concentrates the stabilizing effect in specific areas where it is most needed to prevent tipping, while maintaining narrow dimensions in other areas to minimize weight.
3Ease of manufacture
If lateral indentations are positioned at a large distance from the end face of wearing ribs, then manufacturing is simplified, but the indentations only become effective when wearing ribs are heavily worn
Solution Approach 1:
The lateral indentations are positioned at a specific distance from the end face of the wearing ribs - not too far to delay effectiveness, but not too close to complicate manufacturing. The indentations extend over the height of the outer sides of the protruding wear land sections, creating optimal engagement timing that balances manufacturing ease with extended service life.

AI summary
The link assembly has a stud link, which comprises a fastening hole (11), which is bound by a wall and in which a ring member is hinged. Walls (51) of the fastening hole comprise two contact surfaces (52,53) in the contact area with the ring member. The contact surfaces lies at a distance from each other. The ring member is laminarly connected to the contact surfaces with its inner side (54) and between which a removable wall sections (55) lies.
