Segmented Wheel Hub Centering Seat for Drainage and Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheel hubs for vehicles face challenges in achieving high strength and long durability while maintaining a lightweight design, and they are prone to corrosion due to water accumulation at the wheel center.
Innovation Solution
A wheel hub design featuring a radially segmented centering seat with continuous outer and inner lateral faces, which allows for effective water runoff and improved corrosion protection, combined with a single-piece flange and extension for enhanced strength and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional wheel hub design with solid structure is used, then strength and durability are improved, but weight increases
Solution Approach 1:
The centering seat is divided into multiple centering surface segments arranged circumferentially with spacing between them. This segmentation reduces material usage and weight while maintaining the structural integrity and strength required for wheel hub functionality. The segments are connected through the extension structure, ensuring load distribution and overall strength.
2Ease of manufacture
If a traditional solid centering seat design is used, then manufacturing simplicity is improved, but water accumulation and corrosion increase
Solution Approach 1:
The centering seat is segmented into multiple centering surface segments with circumferential spacing, creating channels for water runoff. This design prevents water accumulation that would otherwise lead to corrosion, while the segments remain connected through the extension structure to maintain manufacturing feasibility and structural integrity.
3Object-affected harmful factors
If centering surface segments are spaced apart, then water runoff is improved, but structural integrity may be compromised
Solution Approach 1:
The centering surface segments are nested within the extension structure, which provides structural support and connects the segments. This nested arrangement allows the segments to be spaced apart for water runoff while the extension structure maintains overall structural integrity and load-bearing capacity.
4Duration of action of stationary object
If a single-piece flange and extension design is used, then strength and durability are improved, but manufacturing complexity increases
Solution Approach 1:
The flange and extension are merged into a single-piece structure, eliminating the need for separate components and fasteners. This integration improves durability by removing potential failure points from joints and interfaces, while the single-piece design actually simplifies manufacturing by reducing assembly steps and quality control requirements.

AI summary
A wheel hub for mounting a wheel to rotate about an axis of rotation, having a flange, which has at least one fastening member, by which a rim of the wheel can be fastened at least in the axial direction of the wheel hub to the flange and thereby to the wheel hub, and having a centering seat formed on an extension projecting axially from the flange of the wheel hub, which centering seat includes multiple centering surface segments successively disposed and spaced apart from each other in the circumferential direction of the wheel hub and facing outwards in the radial direction of the wheel hub, by which segments the rim can be centered relative to the wheel hub in the radial direction thereof, wherein the single-piece extension has an inner lateral face extending continuously in the circumferential direction and facing inwards in the radial direction.
