Hub Balance Block Fixture With Roller And Rubber Sleeve Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balance blocks have limited applicability and do not fit well with the surface of vehicle hubs due to their simple rectangular shape and lack of secure attachment, leading to suboptimal dynamic balancing at high speeds, which affects ride comfort, tire wear, and driving control.
Innovation Solution
A fixture with rollers and rubber sleeves is used to securely attach balance blocks to the hub surface, featuring a base with adjustable components and a chain-driven mechanism for precise positioning and horizontal alignment, ensuring effective dynamic balancing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple rectangular balance block is used, then the device complexity is reduced, but the adaptability to different hub surfaces deteriorates
Solution Approach 1:
The balance block is divided into a base portion and a protruding portion, allowing it to adapt to different hub surface geometries. The base portion provides stable attachment while the protruding portion extends to the required radius, creating a segmented structure that improves adaptability without excessive complexity.
Solution Approach 2:
The balance block incorporates a rotating member that enables dynamic adjustment of the protruding portion's orientation. This dynamic capability allows the balance block to adapt to various hub surface configurations and maintain optimal positioning during wheel rotation, enhancing versatility.
2Ease of operation
If the balance block is simply stuck to the hub surface, then the ease of operation is improved, but the reliability of attachment deteriorates
Solution Approach 1:
The balance block includes pre-configured attachment features such as adhesive surfaces or mounting interfaces that are prepared in advance. This preliminary preparation ensures secure attachment while maintaining simple installation, as the block is designed to be directly mounted without requiring complex assembly steps.
Solution Approach 2:
The balance block incorporates an intermediary attachment mechanism (such as adhesive layer or mounting interface) between the block and hub surface. This intermediary element enhances attachment reliability while keeping the installation process simple, as it provides a dedicated interface for secure bonding.
3Ease of manufacture
If the balance block is not tightly arranged, then the ease of manufacture is improved, but the manufacturing precision deteriorates
Solution Approach 1:
The balance block features a curved or rounded protruding portion that conforms to the curved surface of the wheel hub. This curved geometry allows the block to be tightly arranged against the hub surface while maintaining simple manufacturing processes, as the curved shape naturally accommodates positioning tolerances.
Solution Approach 2:
The balance block incorporates localized precision features (such as refined surfaces or positioning elements) only at critical contact areas with the hub, while other portions maintain simpler geometry. This local quality approach ensures accurate positioning where needed without requiring high precision throughout the entire component, balancing manufacturing ease with positioning accuracy.
