Wheel Hub With Detachable Tire Ring For Rapid Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wheel hub systems for electric vehicles require time-consuming and difficult tire replacement or maintenance, as the entire wheel hub must be removed from the vehicle body, which is inefficient and labor-intensive.
Innovation Solution
A wheel hub design featuring a support ring with a detachable tire quick replacing ring, allowing for rapid tire removal and replacement without disassembling the wheel hub from the vehicle, along with a sealing ring, V-shaped braking groove, and wind pressure water proofing ring for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the motor is accommodated in the wheel hub to form a wheel hub driving system, then the transmission efficiency and energy efficiency are improved, but the weight of the whole wheel increases
Solution Approach 1:
The wheel hub is divided into multiple detachable components: a support ring (non-rotating part containing the motor), a rotor ring (rotating part), and a tire quick replacing ring. This segmentation allows the heavy motor component to remain stationary while only the lighter rotating components are removed during tire maintenance, effectively reducing the operational weight that needs to be handled during tire replacement while maintaining the energy efficiency benefits of the integrated motor-hub system
2Ease of repair
If the whole wheel is removed from the vehicle body for tire maintenance, then the tire can be replaced, but the operation becomes slow and difficult
Solution Approach 1:
The wheel hub is segmented into a stationary support ring and a detachable rotating assembly (rotor ring + tire quick replacing ring). This allows the tire and rotating components to be removed as a separate unit without disturbing the heavy motor-containing support ring, dramatically reducing maintenance time and effort
Solution Approach 2:
The tire quick replacing ring is designed as a separate detachable component that can be extracted from the support ring. This extraction mechanism allows the tire to be removed without taking out the entire wheel hub assembly, eliminating the need for time-consuming complete disassembly and enabling rapid tire replacement in place
3Productivity
If a detachable tire quick replacing ring is added to the wheel hub, then tire replacement becomes rapid and convenient, but the device complexity increases
Solution Approach 1:
The wheel hub is divided into modular segments (support ring, rotor ring, tire quick replacing ring) that can be independently manufactured and assembled. This modularity simplifies the overall design by breaking down a complex integrated hub into manageable components with clear functional boundaries, making the system easier to manufacture and maintain despite the added functionality

AI summary
A wheel hub includes a support ring (1). The support ring(1) includes an integrally formed inner wheel rim (11), a large span dual bearing support frame (12), and a rotor protection frame support groove (13). A lateral end of the support ring (1) is detachably provided with a tire quick replacing ring (2). The inner wheel rim (11) is provided with a first tire sealing face (101). The tire quick replacing ring (2) is provided with a second tire sealing face (201). A wheel hub motor wheel uses the above mentioned wheel hub. An electric vehicle uses the wheel hub motor wheel. Through the above wheel hub motor wheel and the electric vehicle, rapid replacement of a tire or rapid removal of the tire from the wheel hub for maintenance can be implemented without removing the wheel hub of the wheel from a vehicle body; this allows the replacement or maintenance of the tire to be time-saving, effort-saving, and greatly convenient. In addition, the wheel hub also provides a brake radius as large as possible and a maximized rotor space of an external rotor motor.
