Attachable High-Mn Steel Brake Disk for Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake disks made of general carbon steel are heavy, prone to corrosion, and require full replacement when the braking surface wears out, leading to degraded braking performance and increased maintenance costs.
Innovation Solution
An attachable high-manganese steel brake disk design, where the braking surface and structural portions are made of different materials, with a bolt-based fastening system and concave-convex interlocking mechanism, allowing the second disk members with high-manganese steel to be replaced independently, reducing maintenance costs and improving braking performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If general carbon steel is used for brake disks, then manufacturing cost is reduced, but weight increases and fuel efficiency decreases
Solution Approach 1:
The brake disk is divided into two separate components: a structural disk member and a braking surface member. This segmentation allows each component to be optimized independently - the structural member can use lighter high-strength materials while the braking surface uses materials optimized for friction and wear resistance, thereby reducing overall weight without compromising performance or manufacturing cost.
Solution Approach 2:
The invention uses composite construction by combining different materials for the structural member and braking surface member. The structural member may use high-strength low-alloy steel or other lightweight materials, while the braking surface uses carbon steel or composite materials optimized for braking performance. This composite approach reduces weight while maintaining cost-effectiveness through selective material application.
2Ease of manufacture
If general carbon steel is used for brake disks, then manufacturing simplicity is maintained, but corrosion resistance deteriorates
Solution Approach 1:
The brake disk uses composite construction where the structural member can be made from materials with superior corrosion resistance (such as stainless steel or aluminum alloys) while the braking surface member uses conventional carbon steel. This composite material selection improves overall corrosion resistance without significantly complicating manufacturing, as both members are separately manufactured and then assembled.
Solution Approach 2:
By segmenting the brake disk into structural and braking surface members, corrosion protection can be applied differently to each component. The structural member exposed to environmental conditions can use corrosion-resistant materials or coatings, while the braking surface focuses on friction performance. This segmentation allows targeted corrosion protection strategies.
3Strength
If the brake disk is manufactured as an integral structure, then structural strength is improved, but maintenance cost increases when braking surface wears
Solution Approach 1:
The brake disk is segmented into a structural disk member and removable braking surface members. The structural member is designed as a strong, durable component that remains in place, while the braking surface members can be independently removed and replaced when worn. This segmentation maintains structural strength while dramatically reducing maintenance costs, as only the braking surfaces need replacement rather than the entire brake disk.
Solution Approach 2:
The braking surface members are designed as consumable components that can be discarded when worn and replaced with new ones. The valuable structural disk member is recovered and retained, avoiding the need to replace the entire brake disk assembly. This approach reduces maintenance costs by separating the durable structural component from the wear-prone braking surfaces.
4Ease of manufacture
If single material is used for entire brake disk, then manufacturing process is simplified, but braking performance and wear resistance are degraded
Solution Approach 1:
The brake disk employs composite materials with the structural member made from high-strength materials optimized for mechanical strength and the braking surface member made from materials optimized for friction characteristics and wear resistance. This composite material selection improves braking performance and reliability while keeping the manufacturing process relatively simple through separate manufacturing and assembly of the two members.
Solution Approach 2:
Different regions of the brake disk are made from materials with locally optimized properties. The structural member uses materials optimized for strength and structural integrity, while the braking surface uses materials optimized for friction and wear resistance. This local quality differentiation improves overall braking performance while maintaining manufacturing simplicity through separate component fabrication.
5Reliability
If high-manganese steel is used for the entire brake disk, then wear resistance is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The brake disk segments the high-manganese steel material application to only where it is most needed - the braking surface member that直接接触 the brake pads and experiences wear. The structural member can use more conventional, easier-to-manufacture materials. This segmentation achieves wear resistance improvement while reducing overall manufacturing complexity and cost compared to making the entire brake disk from high-manganese steel.

AI summary
An attachable high-manganese steel brake disk includes a first disk member including air vents disposed radially therein to be spaced apart from each other, and a pair of second disk members installed to be attached to two surfaces of the first disk member and having a braking surface in contact with a brake pad. Between the first disk member and the second disk members, at least the second disk members are provided as high manganese steel members.
