Wheel Mounting Member Structure for Deflection and Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle wheel structures with wheel mounting members experience deflection deformation due to reduced rigidity in certain regions, leading to abnormal sounds and potential detachment under external forces like airflow and vibration.
Innovation Solution
A vehicle wheel structure with a wheel mounting member featuring a main engagement section and a sub-engagement section in low-rigidity regions, where the sub-engagement section engages with an engageable target section to stabilize the mounting member, reducing deflection deformation and preventing detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the wheel mounting member is fixed to the wheel by only the engagement between the engagement target section and the engagement section, then the structure is simple and easy to manufacture, but the rigidity decreases in certain regions causing deflection deformation
Solution Approach 1:
The engagement section is divided into a main engagement section and a sub-engagement section. The main engagement section engages with the engagement target section to provide primary fixation, while the sub-engagement section engages with the engageable target section to provide additional support. This segmentation allows the structure to maintain simplicity while improving rigidity by distributing engagement points across multiple locations.
Solution Approach 2:
The sub-engagement section is specifically positioned in the low-rigidity region of the body section to provide localized reinforcement. This local quality approach addresses the rigidity deficiency only where needed, without requiring reinforcement of the entire structure, thus maintaining ease of manufacture while improving overall rigidity.
2Device complexity
If the wheel mounting member is fixed to the wheel by only the engagement between the engagement target section and the engagement section, then the device complexity is low, but deflection deformation occurs under external forces like airflow and vibration
Solution Approach 1:
The engagement section is segmented into main and sub-components, creating a multi-point engagement system. This segmentation enhances stability by distributing mechanical loads across multiple engagement points, reducing the impact of external forces like airflow and vibration on any single point, thereby preventing deflection deformation.
Solution Approach 2:
The sub-engagement section acts as a preventive measure against deflection deformation. By providing additional engagement points in advance, the structure is pre-prepared to withstand external forces, cushioning against potential instability before it occurs.
3Device complexity
If the wheel mounting member is fixed to the wheel by only the engagement between the engagement target section and the engagement section, then the structure is simple, but abnormal sound is generated due to repeated abutment
Solution Approach 1:
The engagement section is divided into main and sub-sections, distributing the contact points across multiple locations. This segmentation reduces the repeated abutment at any single point, thereby minimizing the generation of abnormal sounds while maintaining structural simplicity.
Solution Approach 2:
The sub-engagement section is positioned in the low-rigidity region to locally address the sound generation issue. By providing additional engagement points in this specific area, the repeated abutment is reduced, minimizing abnormal sound generation without requiring changes to the entire structure.

AI summary
A vehicle wheel structure includes: a wheel configured to support a tire and be assembled to a vehicle; and a wheel mounting member that is mounted on the wheel. The wheel mounting member includes a body section, a main engagement section that is provided to the body section and engages with an engagement target section of the wheel, and a sub-engagement section that is provided in a low-rigidity region in which the rigidity relatively decreases in the body section in a state in which the body section is fixed to the wheel by the main engagement section, the sub-engagement section engaging with an engageable target section of the wheel, the engageable target section being different from the engagement target section.
