Split Torsion Axle Joint for Independent Wheel Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing torsion axle assemblies in trailers do not allow for independent adjustment of individual wheels, leading to loss of stability and strength when dealing with uneven terrain or specific loading/unloading requirements.
Innovation Solution
A split torsion axle system with a central joint and bearing assembly that allows each wheel assembly to be independently adjusted, maintaining linear alignment and rotational capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a continuous cross-axle member is used to provide strength and stability, then structural strength is improved, but the ability to independently adjust individual wheels is lost
Solution Approach 1:
The continuous cross-axle member is divided into two separate axle beam portions (first axle beam portion and second axle beam portion) that are connected through a central joint. This segmentation allows each wheel assembly to be independently adjusted while the central joint maintains the structural connection, thereby resolving the contradiction between structural strength and independent adjustment capability.
2Adaptability or versatility
If individual wheel adjustment is enabled, then adaptability to uneven terrain is improved, but structural stability is reduced
Solution Approach 1:
A central joint with bearing assembly acts as an intermediary between the first and second axle beam portions. This intermediary component provides a rotatable connection that maintains structural stability while allowing independent adjustment of each wheel assembly, thereby enabling adaptability to uneven terrain without sacrificing structural stability.
3Adaptability or versatility
If separate wheel assemblies are used on each side, then independent adjustment capability is improved, but additional support components are required
Solution Approach 1:
The central joint combines multiple functions into a single component: it connects the two axle beam portions, provides rotational capability for independent wheel adjustment, and maintains structural alignment. This merging of functions reduces the number of separate support components needed compared to using completely separate wheel assemblies, thereby reducing device complexity while maintaining independent adjustment capability.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables independent adjustment of each wheel, providing stability and strength to trailers, accommodating uneven terrain and unique loading conditions.
Implementation Method 1
The bearing assembly is more specifically configured with a hub that is coupled to the first spindle and a bearing or bearings situated within the hub. The bearings are operatively coupled to an extending portion of the second spindle.

AI summary
A split torsion axle is configured to provide the advantages of a torsion axle while also allowing for the independent adjustment of related wheel assemblies positioned on opposite ends thereof. The split torsion axle also provides for additional stability provided by having a continuous axle member spanning the width of the trailer or vehicle upon which the split torsion axle is deployed. To provide these capabilities, the split torsion axle comprises a first torsion axle beam and a second torsion axle beam, which are rotatably coupled to one another by a central joint. The central joint comprises a first spindle coupled to the first torsion axle beam, a second spindle coupled to the second axle beam, and a bearing assembly rotatably coupling the first and second spindles to one another. Both the first torsion axle beam and the second torsion axle beam are configured to be coupled to respective wheel assemblies.
