Wheel Hub Bushing Plate Assembly for Secure Bidirectional Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wheel and axle interfaces lack sufficient rigidity and secure rotational mechanisms, which can lead to inefficient rotation and potential disengagement of wheels and tires under varying forces and conditions.
Innovation Solution
A wheel hub system with integrated front and back bushing plate assemblies and wheel hub assemblies that form a single fixed structure, featuring axel apertures, positioning ridges, semi-circular notches, and bolt apertures, allowing for secure rotational alignment and attachment of bolts and nuts to facilitate bidirectional rotation of the wheel and tire about an axle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional wheel and axle interfaces are used, then the structure is simpler, but the rigidity and rotational stability are insufficient
Solution Approach 1:
The bushing plate assembly integrates multiple components into a unified structure where the cover plate and bushing structure form a single fixed structure, enhancing rigidity while maintaining manageable complexity through functional integration
Solution Approach 2:
The system employs composite structural design combining bushing structures with cover plates, creating a hybrid assembly that achieves superior rigidity and rotational stability compared to traditional single-material interfaces
2Reliability
If traditional rotational mechanisms are used, then the attachment mechanism is simpler, but the secure rotational capability under varying forces is insufficient
Solution Approach 1:
The semi-circular notches and positioning ridges create a dynamic rotational mechanism that accommodates bidirectional rotation while maintaining secure engagement through geometric constraints that adapt to varying rotational forces
Solution Approach 2:
The semi-circular notches provide curved geometric features that enable smooth bidirectional rotation about the axle while maintaining positive engagement through the arc-shaped geometry that conforms to rotational motion
3Stability of the object's composition
If the wheel hub system is designed for high rigidity, then rotational stability improves, but the manufacturing complexity increases
Solution Approach 1:
The wheel hub system is divided into separable assemblies (bushing plate assemblies with front and back portions) that can be manufactured independently and then assembled, reducing individual component complexity while achieving overall high rigidity through precise assembly interfaces

AI summary
A wheel hub assembly is presented by this disclosure. In one exemplary embodiment, a wheel hub apparatus includes a wheel assembly having front and back bushing plate assemblies. Each bushing plate assembly includes a cover plate attached to a bushing structure. Further, the bushing structure includes an axel aperture, positioning ridges, semi-circular notches, and bolt apertures. Each semi-circular notch corresponds to one of the bolt apertures and is configured to receive and position a bolt in that bolt aperture so that the corresponding bushing plate assembly is rotationally secured to that bolt. The apparatus further includes a wheel hub having front and back wheel hub assemblies and configured to secure a tire. Also, each wheel hub assembly includes a flanged portion forming a cavity with a wheel assembly seat positioned at the center of the cavity and configured to receive the corresponding wheel assembly.
