Brake Pad Locking Device Segmentation for Tool-Free Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disc brake systems face challenges with increased wear on components due to the lack of a simple and efficient assembly and disassembly process, leading to higher maintenance efforts and reduced functional reliability.
Innovation Solution
A two-part locking device with a spring element and a securing element, coupled in a form-fitting manner, allows for easy assembly and disassembly of brake pads without additional tools, featuring a recess in the brake carrier horn that interacts with the locking section of the securing element, enabling automatic adjustment from an unlocked to a locked position during installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the brake pad is equipped with a pad retaining spring and elastically deformable securing elements that positively engage between the brake carrier horn and the brake pad, then the brake pad can be retained in the pad shaft, but the assembly and disassembly of the brake pad require increased effort and additional tools
Solution Approach 1:
The locking device is divided into two separate parts: a spring element and a securing element. These parts are coupled in a form-fitting manner but can move relative to each other, allowing the securing element to be positioned in different states (locked or unlocked) relative to the brake carrier horn recess, enabling tool-free assembly and disassembly while maintaining reliable retention
2Reliability
If the brake pad is equipped with a locking device that has a securing element positively engaging with the brake carrier horn, then the brake pad is prevented from rising out of the pad shaft, but the assembly process becomes more complex requiring additional tools
Solution Approach 1:
The locking device is segmented into a spring element and a securing element that are coupled but can move relative to each other. This segmentation allows the securing element to be positioned in an unlocked state (where it does not engage the brake carrier horn) or a locked state (where it engages the recess), simplifying the assembly process while maintaining reliability
Solution Approach 2:
The securing element is designed to be movable relative to the spring element, allowing it to transition between different positions. This dynamic capability enables the securing element to engage or disengage from the brake carrier horn recess as needed, providing both reliable retention and easy assembly without additional tools
3Ease of manufacture
If the brake carrier horns are aligned parallel to one another, then the brake pad achieves a self-locking effect that protects components from wear, but abandoning this alignment is necessary to enable simple assembly without the self-locking effect
Solution Approach 1:
The locking device is designed to automatically transition from an unlocked position to a locked position during the assembly process itself. The securing element is preliminarily positioned in the unlocked state for easy insertion, then automatically engages the brake carrier horn recess as the brake pad is installed, providing protection against component wear without complicating the assembly process
