Brake Dust Filter Mounting for Stable Disc Brake Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake dust particle filter arrangements face challenges in maintaining a fixed installation position relative to disc brake arrangements, particularly in the circumferential and radial directions, which can lead to unnecessary movement and wear, and complicate assembly and disassembly processes due to limited installation space.
Innovation Solution
The introduction of a holding component with a male connection geometry that directly engages with a female connection geometry on the housing, allowing for immobilization in the angular position in the circumferential and radial directions, reducing or eliminating degrees of freedom and enabling tool-free assembly and disassembly, with optional additional fixation using screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the brake dust particle filter is held in a fixed installation position using traditional fastening methods, then the position stability is improved, but the assembly and disassembly process becomes more complex and time-consuming
Solution Approach 1:
The connection geometry is segmented into male and female parts that can easily engage and disengage. The male connection geometry on the retaining component fits into the female connection geometry on the housing, creating a segmented but stable connection that simplifies assembly while maintaining position stability.
Solution Approach 2:
The brake dust particle filter assembly is designed to be self-aligning through the complementary male and female connection geometries. The groove in the housing automatically guides the male connection geometry during assembly, eliminating the need for complex alignment procedures or additional alignment tools.
2Reliability
If the brake dust particle filter is held in a fixed installation position with multiple fastening points, then the fixation reliability is improved, but the installation space requirement increases
Solution Approach 1:
The connection solution utilizes the axial dimension by extending the male and female connection geometries along the axial direction. The groove extends axially to provide multiple engagement points, achieving reliable fixation through extended engagement in one dimension rather than requiring multiple separate fastening points in different locations.
Solution Approach 2:
The male connection geometry is nested within the groove of the female connection geometry. This nested arrangement provides multiple contact surfaces and engagement points within a compact space, achieving reliable fixation without requiring additional installation space for separate fastening mechanisms.
3Ease of operation
If the brake dust particle filter allows freedom of movement during installation, then the ease of installation is improved, but the risk of misalignment with surrounding components increases
Solution Approach 1:
The male and female connection geometries act as intermediary guiding elements during installation. The groove in the housing serves as a guide that automatically aligns the male connection geometry as it is inserted, providing precise alignment without requiring the installer to manually position the components with high precision.
Solution Approach 2:
The connection geometries are pre-configured with complementary shapes that automatically perform the alignment function during the insertion process. The groove's geometry is designed in advance to guide the male connection geometry into the correct position, eliminating the need for preliminary manual alignment adjustments.

AI summary
The invention relates to a brake dust particle filter assembly (1) for collecting brake dust particles created when a disc brake assembly (2) is actuated, comprising: a brake dust particle filter, which has a ring-segment-shaped housing (5) for at least partially receiving a brake disc (4) of the disc brake assembly (2), the housing (5) having two housing side walls (6, 7) distanced axially from one another and a circumferential housing wall (8) extending between the housing side walls (6, 7) in the circumferential direction; and comprising at least one filter element arranged in the housing (5); and comprising a holding component (9), which is designed to hold the brake dust particle filter in an installed position that is stationary relative to the disc brake assembly (2). A brake dust particle filter assembly (1) is provided that reduces the movement clearance between the brake dust particle filter and the disc brake assembly (2) at least in the circumferential direction and the radial direction. To this end, the holding component (9) and the housing (5) are fixable relative to one another, at least in respect of their angular position in the circumferential direction and/or their radial position, directly by a mutual engagement in the installed position, the mutual engagement being achieved by means of an interlocking engagement of at least one male connection geometry (10) with at least one corresponding female connection geometry (13). The invention further relates to a disc brake assembly (2) and to a vehicle.
