Brake Carrier Converging Guide Contours for Disc Brake Pad Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of brake pads in disc brakes is complicated due to canting issues when using guide contours parallel to the carrier horns, making it difficult to position the pads correctly during the installation process.
Innovation Solution
A brake carrier design featuring converging guide contours on the carrier horns that guide the brake pad into a precise insertion position, ensuring it is centered and easy to insert axially into the pad shaft, with additional mounting areas to prevent shifting during the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If guide contours parallel to carrier horns are used, then brake pad insertion is guided, but canting occurs during insertion making installation difficult
Solution Approach 1:
The guide contours are designed to converge towards the bridge rather than running parallel, creating an asymmetric configuration that naturally guides the brake pad into correct alignment while preventing canting during insertion
2Reliability
If brake pads are radially fixed in form-fitting manner on carrier horns, then radial fixation is achieved, but complex axial movement is required for insertion
Solution Approach 1:
The brake pad is pre-positioned in a pushed-in position at the side of the pad shaft using the converging guide contours, which prepares the correct alignment before the final axial insertion into the pad shaft, simplifying the overall installation process
3Productivity
If simple radial insertion is used, then insertion speed is improved, but additional holding systems are required to prevent brake pads from falling out
Solution Approach 1:
The guide contours and bearing surfaces are merged into a single integrated structure on the carrier horns, combining the guidance function and radial fixation function into one component, eliminating the need for separate holding systems

AI summary
A brake carrier (1, 100) for a disc brake of a commercial vehicle, which disc brake can be actuated pneumatically or by electric motor, has an attachment region (2, 120) for fixing on a vehicle axis and at least one lining shaft for receiving and supporting at least one brake lining (9), wherein the lining shaft is formed by way of an inlet-side carrier horn (4, 140), an outlet-side carrier horn (5, 150) and a bridge (3, 130) which connects the inlet-side carrier horn (4, 140) and the outlet-side carrier horn (5, 150), wherein regions of the bridge (3, 130) which adjoin the carrier horns (4, 5, 140, 150) form bearing surfaces (31, 32, 131, 132) for radially supporting the at least one brake lining (9), wherein the respective guide contours (44, 54, 144, 154) for guiding the brake lining (9) into a push-in position are arranged to the side of the lining shaft on a side surface (42, 52, 142, 152) of the carrier horns (4, 5, 140, 150), in which push-in position the brake lining (9) can be pushed axially with respect to the vehicle axle into the lining shaft between the carrier horns (4, 5, 140, 150). Furthermore, a disc brake of a commercial vehicle is described, which disc brake can be actuated pneumatically or by electric motor.
