Floating Caliper Brake Adjustment for Wear Clearance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Floating caliper brakes face challenges in maintaining a delay-free braking operation and ensuring sufficient clearance between brake pads and the brake disc, especially when wear occurs, which can lead to inadequate spacing and potential engagement issues.
Innovation Solution
The floating caliper brake design incorporates a guide mechanism with a gear section and transmission sections that adjust the position of the brake pads relative to the brake disc, allowing for optimal clearance settings through a wear-dependent mechanism, ensuring the brake pads remain spaced apart when not in use and engage properly when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the brake pads are positioned close to the brake disc to ensure delay-free braking operation, then the braking response time is improved, but the risk of premature engagement and unnecessary contact increases
Solution Approach 1:
The brake caliper is designed to be movable relative to the brake carrier along the axial direction, allowing the brake pads to dynamically adjust their position. The guide mechanism enables the caliper to float and self-position, optimizing the clearance between brake pads and disc while preventing premature engagement through controlled movement rather than fixed positioning
2Reliability
If the brake pads are spaced apart from the brake disc to prevent unnecessary contact, then the reliability is improved, but the braking response time increases due to larger clearance
Solution Approach 1:
The floating caliper brake system performs self-adjustment through its guide mechanism, which allows the caliper to automatically position itself relative to the brake disc based on operational conditions. This self-positioning capability eliminates the need for external adjustment mechanisms while maintaining optimal clearance and preventing premature engagement
3Device complexity
If a fixed position mechanism is used to maintain brake pad clearance, then the device complexity is reduced, but the adaptability to wear conditions deteriorates
Solution Approach 1:
The guide mechanism provides dynamic adaptability through controlled movement of the brake caliper along the axial direction. This dynamic positioning capability allows the system to automatically compensate for wear conditions without requiring complex adjustment mechanisms, achieving adaptability through simple guided motion rather than fixed positioning

Function Achieved in This Case
This design guarantees a consistent and optimal clearance, preventing premature engagement due to wear, thus ensuring a delay-free braking operation and maintaining the necessary spacing to avoid unnecessary contact between brake pads and the brake disc.
Implementation Method 1
The gear section is connected to the second transmission section via an internal thread and an external thread, so that rotating the gear section about a central axis extending along the axial direction relative to the second transmission section results in an adjustment of the second transmission section relative to the gear section along the axial direction
Implementation Method 2
The gear section is connected to the second transmission section via an internal thread and an external thread, so that rotating the gear section about a central axis extending along the axial direction relative to the second transmission section results in an adjustment of the second transmission section relative to the gear section along the axial direction
Implementation Method 3
The guide mechanism comprises a guide element that extends from a fastening region, by which the guide element is fastened to a section of the brake caliper, towards a free end, and a bore section extending along the axial direction in a section of the brake carrier. A section of the guide element is arranged in the bore section

AI summary
Depicted and described is a floating caliper brake comprising an adjustment device, wherein when a second distance between a first end section and a second end section is equal to, or greater than, a predefined distance, an actuation section of an adjustment element engages with a gear section in such a way that an increase in the second distance of the actuation section of the adjustment element causes the gear section to rotate about a central axis relative to a second transmission section, in such a manner that the second transmission section moves away from the gear section along the axial direction.
