Replaceable Brake Disc Plates With Inclined Ledge Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake disc designs for vehicles face challenges with the wear and replacement of disc plates, as screws or bolts used for fixation lead to reduced strength and uneven wear, making it difficult to replace the disc plates without affecting the brake pads.
Innovation Solution
A brake disc design featuring inclined ledges and an enveloping sleeve that secures disc plates without using screws or bolts through the wear surface, allowing for easy replacement of disc plates without affecting the brake pads, and utilizing connecting members to prevent rotation and enhance stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws or bolts are used to secure disc plates to the central disc body, then the disc plates can be fixed in place, but the screws or bolts become worn and reduced in strength, and cause uneven wear on the brake pads
Solution Approach 1:
The invention removes the harmful fixation elements (screws or bolts) from contact with the brake pads by extracting them from the wear path. The disc plate is secured to the central disc body through a mounting structure that positions the fixation components away from the friction surface, eliminating their direct involvement in the braking process and preventing the wear and strength reduction problems they caused.
Solution Approach 2:
The invention introduces an intermediary mounting structure that mediates between the disc plate and the central disc body. This intermediate mechanism provides the necessary fixation while keeping the securing elements separate from the brake pad contact area, thus preventing the wear and deformation issues that would otherwise affect the fixation components.
2Stability of the object's composition
If screws or bolts are used to secure disc plates, then the disc plates can be fixed, but it becomes difficult to replace the disc plates due to wear of the screw or bolt heads
Solution Approach 1:
The invention extracts the worn screw or bolt heads from the replacement process by removing the fixation components from the service path. The new mounting structure allows disc plate replacement without the need to deal with degraded screw or bolt heads, significantly improving ease of repair while maintaining fixation stability through the alternative mounting mechanism.
Solution Approach 2:
The invention employs a mounting structure where the fixation elements are designed to be easily replaced or are part of a disposable/discardable assembly. This approach prioritizes ease of repair by allowing quick replacement of the entire disc plate assembly without the complexity of removing worn fixation components, effectively treating the fixation system as a short-living, easily replaceable element.
3Stability of the object's composition
If screws or bolts are used to secure disc plates, then the disc plates can be attached to the central disc body, but the presence of screws or bolts adds to the uneven wear of the brake pads
Solution Approach 1:
The invention extracts the harmful influence of screws or bolts from the braking interface by removing them from proximity to the brake pads. The new mounting structure positions all fixation elements away from the friction surface, eliminating the source of uneven wear they caused while maintaining secure attachment of the disc plate through the alternative mounting mechanism.

AI summary
A brake disc configured to be connected to a vehicle axle and to be squeezed between brake pads, comprising a central disc body (30), first and second disc plates (36, 38) releasably securable to the central disc body. Each disc plate has a wear surface and a disc body facing surface. The brake disc has a geometrical centre axis. Each disc plate has an inner periphery and an outer periphery extending from the wear surface to the disc body facing surface. A first ledge (60) mates with the inner periphery of the first disc plate, and a second ledge (60) mates with the inner periphery of the second disc plate. Each ledge comprises at least a ledge portion which is inclined relative to the geometrical centre axis for counteracting axial movement of the disc plates relative to the central disc body.
