Static Wheel Weight on Work Vehicle Axle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increase in speed limits for work vehicles like tractors poses challenges for traditional wheel weight designs, which were primarily intended for lower speeds, leading to issues with rotation and safety, as well as complexity in assembly and maintenance.
Innovation Solution
A vehicle wheel structure with a static wheel weight integrated into a support part extending beyond the shaft transmission part, where the wheel weight is fixed with respect to the vehicle frame, preventing rotation and simplifying access and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wheel weight is integrated within the wheel rim or fixed to specific portions of the wheel rim, then the wheel weight can be securely positioned, but the design becomes complex and maintenance becomes difficult
Solution Approach 1:
The axle is divided into a fixed portion and a mobile portion, with the wheel weight integrated into the fixed portion. This segmentation allows the wheel weight to be securely positioned while simplifying the overall assembly structure and maintenance procedures.
2Device complexity
If the wheel weight is designed for lower displacement speeds, then the design can be simpler, but it becomes unsafe and unreliable at higher speeds up to 50-65 Km/h
Solution Approach 1:
The wheel weight is integrated into the fixed portion of the axle, which remains stationary relative to the vehicle frame while the mobile portion rotates. This dynamic configuration ensures the wheel weight maintains proper positioning and balance at higher speeds without requiring complex high-speed specific designs.
3Object-affected harmful factors
If the wheel weight is made static with respect to the vehicle frame, then kinetic energy-related risks are eliminated, but the wheel weight must be precisely positioned and secured
Solution Approach 1:
The wheel weight receiving portion is pre-formed as an integral part of the fixed portion of the axle during manufacturing. This preliminary action ensures precise positioning and secure attachment of the wheel weight, eliminating the need for complex assembly operations while maintaining static positioning to eliminate kinetic energy risks.
