Segmented Tractor Wheel Rim for Tire Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large and wide tractor tires face challenges with uneven tire pattern penetration and air pressure regulation, leading to reduced stability and increased costs due to high prices and short service life, while traditional designs are inefficient in material usage and production time.
Innovation Solution
A wheel construction with a hub plate featuring offset flaps that increase contact area and flexibility, allowing for better power transmission and reduced air pressure instability, using a method that involves machining plane steel alloys with cutting tools to form a sinusoidal outer periphery, enabling the use of two traditional tires instead of one wide tire, thus reducing production costs and time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a single wide tire is used to reduce base impact, then the tire width increases to distribute weight, but the tire pattern penetration becomes uneven and stability decreases
Solution Approach 1:
The invention divides the wheel assembly into two separate wheel rims instead of using one wide wheel rim, allowing each tire to maintain proper contact pattern penetration while distributing the weight load to reduce base impact
2Weight of moving object
If a single wide tire is used to reduce base impact, then the tire width increases, but air pressure regulation becomes difficult and service life decreases
Solution Approach 1:
The invention segments the single wide tire into two separate tires, each with its own air pressure regulation, making it easier to maintain proper pressure levels and extend service life while still achieving reduced base impact
3Device complexity
If traditional wheel rim designs are used, then the structure is simple, but material usage is inefficient and production time increases
Solution Approach 1:
The hub plate is designed with a universal offset structure that can accommodate different wheel rim configurations and tire arrangements, making it a multi-functional component that reduces overall production time and material usage while maintaining structural integrity

AI summary
The present invention concerns a wheel (1) construction as well as a method for making such a wheel (1) construction for e.g. a construction or agricultural machine, such as a tractor, wherein the wheel (1) construction at least includes a wheel rim (2) made up of a rim ring (2) for mounting a first tyre and further includes a hub plate (3) which at its outer periphery (11) is fixed to the rim ring (2) at a distance XI from an annular edge thereof, and extending internally in the first rim ring (2) between the rim ring (2) and the central axis of the first wheel rim (rotary axis of the wheel rim), the first hub plate (3) at an inner periphery (9) including a number of holes (8) and a contact face for mechanical and detachable fixing to either a central hub plate (4) or directly to a hub of a vehicle.
