Removable Wheel Hub Bolt Ring for Faster Disc Rotor Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing air disc braking system requires the complete disassembly of the hub and rotor assembly for disc rotor replacement, leading to high labor costs and safety risks due to the heavy weight of the assembly, necessitating a more efficient method for maintenance.
Innovation Solution
A removable bolt ring assembly with a tongue and groove system and slide locking collar allows for the disc rotor to be replaced through the outboard side of the hub, eliminating the need for full disassembly by using a bayonet-style mounting system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the entire hub and rotor assembly is disassembled for disc rotor replacement, then the replacement can be completed, but the labor time and cost increase significantly
Solution Approach 1:
The hub assembly is divided into separate functional components: a stationary hub body containing bearings and seals, and a removable bolt ring that attaches the wheel. This segmentation allows the bolt ring to be detached and reattached without disassembling the entire hub assembly, enabling quick disc rotor replacement while maintaining bearing support.
Solution Approach 2:
The bolt ring is designed with dynamic mounting and dismounting capabilities through the tongue and groove system with locking tabs. This allows the bolt ring to be quickly attached and detached multiple times without permanent installation, facilitating rapid disc rotor replacement while maintaining structural integrity during operation.
2Ease of repair
If the entire hub and rotor assembly is disassembled for disc rotor replacement, then the replacement can be completed, but the labor cost increases due to multiple steps
Solution Approach 1:
The hub assembly is divided into separate functional components: a stationary hub body containing bearings and seals, and a removable bolt ring that attaches the wheel. This segmentation allows the bolt ring to be detached and reattached without disassembling the entire hub assembly, enabling quick disc rotor replacement while maintaining bearing support.
Solution Approach 2:
The bolt ring is extracted as a separate removable component from the hub assembly. By taking out the bolt ring design, the patent enables replacement of the disc rotor without removing bearings, seals, or the hub body, significantly simplifying the replacement process to just a few steps.
