Abstract: 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.
