Integrated Brake Dust Suction Layout for Commercial Disc Brakes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake dust collection systems for commercial vehicles are inefficient in capturing fine brake dust particles, which pose health and environmental hazards due to their small size and chemical composition, and often require additional space and complex installations.
Innovation Solution
A suction device is designed to be integrated between the brake caliper and carrier, featuring a basic body with a suction line and intake opening arrangement that can be connected to a vacuum, allowing for effective suction of brake dust particles from both sides of the brake disc, reducing installation space requirements and enabling targeted dust collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional brake dust collection systems are used, then brake dust particles can be collected, but the system requires additional space and complex installation
Solution Approach 1:
The suction device is merged with the brake caliper assembly, where the suction opening arrangement is integrated into the caliper structure itself. This eliminates the need for separate collection housings and reduces installation complexity while maintaining effective brake dust capture from both sides of the brake disc
Solution Approach 2:
The brake caliper structure is given multiple functions: it not only applies braking force but also houses the suction opening arrangement for dust collection. The base body serves both as structural support and as the housing for the suction line and vacuum connection, reducing the need for additional components
2Reliability
If traditional brake dust collection systems are used, then brake dust particles can be collected, but the system requires additional installation space
Solution Approach 1:
The suction device components are nested within the existing brake caliper structure. The suction line is arranged within the base body, and the suction opening arrangement is integrated into the caliper assembly, allowing the dust collection system to occupy the same space as the braking mechanism without requiring additional installation area
3Device complexity
If suction device is integrated between brake caliper and carrier, then space is saved and installation is simplified, but the suction effectiveness must be maintained
Solution Approach 1:
The suction opening arrangement is positioned at specific locations on the brake caliper that are optimal for capturing brake dust particles. The intake openings are arranged to face the brake disc surfaces where dust is generated, ensuring effective local suction while maintaining the integrated compact design
