Concave Chin Ring Heat Shield for Tire Heat Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chin rings become excessively hot and retain heat, posing thermal and safety risks to the wheel and tire, while blocking radiant and convective heat from reaching the tire.
Innovation Solution
A modified chin ring design featuring a radially extending flat portion and a concave portion that directs convection heat away from the wheel assembly, ensuring it remains below the wheel flange diameter and blocks the line of sight between braking components and the tire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional chin ring is used to block radiant and convective heat from reaching the tire, then the tire is protected from heat damage, but the chin ring itself becomes excessively hot and retains heat, posing thermal risks to the wheel assembly
Solution Approach 1:
The chin ring is divided into multiple arcuate panels or sections that are attached together to form a complete cylindrical heat shield. This segmentation allows heat to dissipate between panels and prevents the entire structure from becoming uniformly hot, while still maintaining effective heat blocking capability.
Solution Approach 2:
The chin ring is designed with a specific axial length dimension that is sufficient to block the line of sight between braking components and the tire. By optimizing this dimensional parameter, the shield effectively blocks radiant heat while the segmented structure manages thermal accumulation in the radial direction.
2Object-affected harmful factors
If a chin ring blocks convection and radiation heat from braking components, then the tire is protected from heat, but the area between the wheel and heat sink components becomes very hot, affecting wheel and brake thermal performance
Solution Approach 1:
The chin ring acts as an intermediary heat shield positioned between the braking components and the wheel assembly. It intercepts and reflects radiant heat away from critical components while its segmented cylindrical structure allows controlled heat dissipation, preventing excessive heat accumulation in the wheel-brake assembly area.

Function Achieved in This Case
The modified chin ring design enhances thermal performance by reducing heat retention and improving cooling efficiency for the wheel assembly components, including the tire, while effectively blocking radiant heat from reaching the tire.
Implementation Method 1
a second, concave portion extending generally axially away from the first portion to a second chin ring end... directs convection heat away from the wheel assembly
Implementation Method 2
block a line of sight between the braking components and the tire... effectively blocking radiant heat from reaching the tire

AI summary
A chin ring heat shield for a wheel assembly is provided. The chin ring heat shield is arranged to provide a shield between convection and radiation heat from braking components and a tire of the wheel assembly. The chin ring includes a first, radially extending, flat portion extending from a first chin ring end and a second, concave portion extending generally axially away from the first portion to a second chin ring end. The axial length from the first chin ring end to the second chin ring end is sufficient to block a line of sight between the braking components and the tire when the chin ring is mounted between the braking components and the tire.
