Brake Carrier Cavity Layout for Disc Brake Dust Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disc brake solutions for utility vehicles struggle to effectively prevent the emission of brake dust into the environment without encapsulating the brake, which can lead to heating issues and reduced suction efficiency due to turbulence.
Innovation Solution
A brake carrier with a frame-like basic body and bridge struts, featuring a cavity with inlet and outlet openings in the disc-encompassing portions, allows for the extraction of brake dust without additional encapsulation, using a suction device and suction pipe to collect the abraded material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If complete encapsulation by cover plates is used to trap brake dust, then brake dust emission is reduced, but brake pads and brake disc experience undesired heating
Solution Approach 1:
The brake carrier is divided into multiple functional zones: a frame-like basic body for structural support, disc-encompassing portions for localized dust collection, and a cavity for receiving abraded material. This segmentation allows dust extraction without complete encapsulation, maintaining heat dissipation while capturing brake dust through the cavity and outlet opening
Solution Approach 2:
The harmful brake dust is extracted from the braking system through the outlet opening that leads away from the brake disc and pads. The cavity acts as a collection chamber that removes dust particles from the braking zone, preventing their emission while leaving the braking components exposed for proper thermal management
2Object-generated harmful factors
If additional cover plates or shielding plates are installed to collect brake dust, then dust emission is reduced, but device complexity increases
Solution Approach 1:
The dust collection functionality is merged into the brake carrier itself through integrally formed disc-encompassing portions and a cavity. This eliminates the need for separate cover plates or shielding plates, as the brake carrier's own structure provides both mechanical support and dust extraction capabilities through the outlet opening
Solution Approach 2:
The brake carrier serves multiple functions simultaneously: it provides structural support for the brake pads, encompasses the brake disc for alignment, collects abraded material in its cavity, and extracts dust through the outlet opening. This multi-functionality reduces the need for additional components while achieving effective dust emission control

Function Achieved in This Case
This solution effectively prevents brake dust from escaping into the environment, reduces turbulence, and avoids the heating issues associated with complete encapsulation, while maintaining efficient suction power for particle collection.
Implementation Method 1
A cavity (61) is provided in at least one of the two disc-encompassing portions (6, 7). This cavity has at least one inlet opening (62) for sucking-in abraded material arising during braking operations

AI summary
A brake carrier for a disc brake of a utility vehicle has a frame-shaped basic body with two bridge struts which are aligned parallel to each other and on each of which a pad slot for receiving a brake pad is integrally formed, and respective disc-encompassing portions connecting the ends of the bridge struts to one another, wherein a cavity is provided in at least one of the two disc-encompassing portions. The cavity has at least one inlet opening for sucking in abraded material arising during braking operations. The inlet opening is open toward an interior space surrounded by the frame-shaped basic body. An outlet opening discharges the abraded material that has entered through the inlet opening.
