Disc Brake Lining Carrier Rib Structure for Edge Wear Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disc brake lining carriers face challenges in maintaining dimensional accuracy and preventing wear, tilting, and damage to guide faces, particularly at the edge regions, which can lead to rattling noises and reduced service life due to high operational stresses and material fatigue.
Innovation Solution
Incorporating a reinforcing rib on the lining carrier, which extends axially over its width and is centrally located in the recess, to dissipate stresses and reduce material fatigue, while being cast as a single piece to minimize production costs and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the lining carrier is made as a simple plate structure, then the manufacturing cost is low and production is simple, but the service life is reduced due to stress concentrations and material fatigue at the edge regions
Solution Approach 1:
The patent applies local quality by adding a reinforcing rib specifically at the edge region of the lining carrier where stress concentrations occur during braking. This localized reinforcement strengthens the critical area without requiring to strengthen the entire structure, thereby extending service life while maintaining manufacturing simplicity and controlling costs.
2Reliability
If the edge regions are reinforced to prevent wear and tilting, then the reliability increases, but the material outlay and manufacturing complexity increase
Solution Approach 1:
The reinforcing rib is positioned specifically at the edge region where dimensional accuracy and wear resistance are critical. This localized approach provides the necessary reinforcement for reliability while minimizing the additional material required compared to reinforcing the entire lining carrier structure.
Solution Approach 2:
The patent employs a composite structure combining the base lining carrier material with an additional reinforcing rib structure. This composite approach enhances the mechanical properties at the critical edge region, providing improved wear resistance and tilting prevention while using material efficiently only where needed.
3Duration of action of moving object
If a reinforcing rib is added to reduce stresses, then the service life increases, but the manufacturing complexity and production costs increase
Solution Approach 1:
The reinforcing rib is integrated into the lining carrier as a unified structure, merging the reinforcement function with the existing carrier geometry. This integration allows the component to be manufactured as a single piece using conventional casting or forming processes, avoiding the need for separate assembly steps and maintaining manufacturing simplicity despite the added structural feature.
