Disc Brake Caliper Cover Assembly Using Elastic Locking Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of a cover component to a caliper in disc brakes is not efficiently facilitated by existing technologies.
Innovation Solution
A disc brake design that includes a cover member covering a recessed part of the caliper and a locking member connected to the cover member, which is locked to a locked part on the caliper, allowing the cover member to come into contact with a bridge part, thereby simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a cover component is mounted on a caliper to improve appearance, then the aesthetic quality is improved, but the assembly complexity increases
Solution Approach 1:
The cover component is divided into a cover body and a separate locking member. The locking member is inserted through the cover body to form an integrated assembly that then attaches to the caliper. This segmentation allows the cover and locking mechanisms to be manufactured and prepared separately, simplifying the final assembly process while maintaining structural integrity.
Solution Approach 2:
The locking member is pre-inserted through the cover body before the cover assembly is attached to the caliper. This preliminary action prepares the locking mechanism in advance, so that during final assembly, the locking member can immediately engage with the locking groove on the caliper without requiring additional steps, thereby simplifying the overall assembly process.
2Reliability
If a locking mechanism is added to secure the cover member, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The locking member is designed to automatically engage with the locking groove on the caliper through its own elastic deformation. When the locking member is inserted, its elasticity causes it to deform and snap into the locking groove, creating a self-locking mechanism that secures the cover without requiring additional locking components or complex assembly steps, thereby improving reliability while maintaining simplicity.
3Ease of manufacture
If the cover member structure is simplified to ease assembly, then the ease of manufacture is improved, but the durability may deteriorate
Solution Approach 1:
The locking member is designed with specific elastic parameters that allow it to deform during assembly and then maintain a secure locked state. By carefully controlling the elastic properties and geometric parameters of the locking member, the design achieves both easy assembly (through simple insertion) and high durability (through reliable elastic locking that prevents disengagement under operational stresses).

AI summary
This disc brake includes a mounting member, a pair of brake pads, a caliper, and a cover member. The caliper includes a cylinder part having a cylinder hole in which a piston for moving one of the pair of brake pads is disposed, a bridge part extending across an outer circumferential surface of a disc from the cylinder part in a direction of a rotating axis of the disc, a plurality of claw parts extended toward inside from the bridge part in a radial direction of the rotating axis of the disc and disposed on an opposite side from the cylinder part with the disc interposed between the plurality of claw parts and the cylinder part, the recessed part provided between the plurality of claw parts and opening in a position opposing the cylinder, and a locked part formed on an inner circumferential surface of the recessed part.
