Disk Brake Frame Structure to Block Snow Around Brake Pads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In disk brakes with a floating-type caliper, snow can accumulate and cause malfunctions or deformation due to protrusions, and existing guards are insufficient as snow can still enter from around these guards.
Innovation Solution
A disk brake design featuring an attachment member with outer circumferential frame portions and a coupling beam that extend to cover the disk and support brake pads, positioning the support main body portions on the disk-axially outward side to prevent snow accumulation and ensure smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spring pad protrudes from the front surface of the attachment member, then the brake pad can be properly positioned and supported, but snow can accumulate around the protrusion portion causing malfunction or deformation
Solution Approach 1:
The patent extends the protective frame in the disk circumferential direction to create a three-dimensional enclosure that prevents snow from reaching the spring pad protrusion. By adding this circumferential extension, the design transforms a two-dimensional surface problem into a three-dimensional protective space, eliminating snow accumulation while maintaining brake pad positioning functionality.
Solution Approach 2:
The patent employs a frame structure that acts as a protective shell or barrier around the spring pad area. This frame extends from the attachment member to create a physical barrier that shields the protrusion portion from snow intrusion, allowing the spring pad to function without snow-related malfunctions or deformation.
2Object-affected harmful factors
If existing guard structures are added to protect the spring pad, then some snow protection is provided, but snow can still enter from parts around the guard making the protection insufficient
Solution Approach 1:
The patent integrates the protective frame as part of the attachment member's own structure rather than adding a separate guard component. The frame serves dual functions: structurally supporting the brake assembly and protectively enclosing the spring pad area. This multi-functionality provides comprehensive snow protection without increasing device complexity.
Solution Approach 2:
The protective frame is merged with the attachment member structure, combining the support function and protection function into a single integrated component. This eliminates the need for separate guard structures and provides comprehensive snow protection that prevents snow from entering from any direction around the spring pad.
3Object-affected harmful factors
If the attachment member structure is extended to cover the disk circumferentially, then snow protection is improved, but the structural complexity and material usage increase
Solution Approach 1:
The protective frame is segmented into portions that extend from the attachment member in the disk circumferential direction, creating discrete protective zones around the spring pad area. This segmentation provides effective snow protection while using minimal additional material compared to a complete circumferential enclosure.

AI summary
This disk brake includes an attachment member that has support portions movably supporting a pair of brake pads, and a caliper that pressurizes the brake pads against a disk. The attachment member has outer circumferential frame portions, a coupling beam portion, and support main body portions. The outer circumferential frame portions extend in a disk circumferential direction so as to cover the disk while straddling the disk. The coupling beam portion couples the support portions to each other. The support main body portions form the support portions. The outer frame constituting portions constitute the outer frames of the support main body portions. Positions of disk-axially outward side end surfaces in a disk axial direction are the same as positions of the disk-axially outward side end surfaces of the caliper or on sides outward in the disk axial direction.
