Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heavy vehicles, such as trucks and buses, are equipped with wheels that have a fixed camber angle, which affects driving performance and tire wear, and there is a need to improve driving performance and reduce tire wear.
Innovation Solution
A wheel assembly with an angular adjustment device that allows for the adjustment of the camber angle of the wheel, comprising a thrust element and a support element with different degrees of freedom, enabling precise adjustment of the pin's inclination relative to the vertical.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the camber angle is fixed, then the wheel assembly structure is simple, but the tire wear increases and driving performance deteriorates
Solution Approach 1:
The invention transforms the fixed camber angle structure into a dynamic adjustable structure. The wheel assembly incorporates an adjustment device that allows the camber angle to be modified, enabling the system to adapt to different operating conditions and reduce tire wear while maintaining structural feasibility.
2Ease of manufacture
If the camber angle is fixed, then the wheel assembly structure is simple, but the driving performance deteriorates
Solution Approach 1:
The invention introduces adjustability to the camber angle through a dedicated adjustment device. This allows the wheel assembly to dynamically adapt its geometry to optimize driving performance under varying conditions, while the overall structural complexity remains controlled through modular design.
3Reliability
If the camber angle is adjustable, then the tire wear is reduced, but the wheel assembly structure becomes complex
Solution Approach 1:
The invention divides the wheel assembly into distinct functional modules: the wheel hub, the adjustment device, and the support structure. This segmentation allows the camber angle adjustment function to be isolated in a dedicated subsystem, making the overall complex structure more manageable and maintainable while achieving the tire wear reduction benefit.
4Reliability
If the camber angle is adjustable, then the driving performance is improved, but the wheel assembly structure becomes complex
Solution Approach 1:
The wheel assembly is segmented into functional modules with the adjustment device as a separate subsystem. This modular approach enables the complex adjustment functionality to be implemented while keeping the overall structure organized and maintainable, achieving improved driving performance without excessive complexity.
