Triple axle with rubber torsion mechanism

摘要

A preferred embodiment of the present invention includes a triple torsion axle system and kit with various features to help reduce or prevent damage that otherwise may occur with large loads. For example, each axle assembly includes larger diameter caps on the ends of each torsion bar to prevent the bar from pulling out of its outer tube during high side loads. In another example, the outer end of the torsion bar has a rounded surface that is fixed to a swing arm so as to better equalize the stress around the weld joint. Additionally, the triple torsion axle is configured such that when the vehicle is unloaded, the middle axle assembly supports more weight than the two adjacent axle assemblies. However, when the vehicle is loaded, all three axle assemblies provide similar support to the vehicle.

主权项

1. A triple axle system for a vehicle, comprising:
a first axle assembly fixed to a bottom of said vehicle; a second axle assembly fixed to said bottom of said vehicle; and, a third axle assembly fixed to said bottom of said vehicle and located between said first axle assembly and said second axle assembly; wherein said third axle assembly provides more support to said vehicle than said first axle assembly and said second axle assembly when said vehicle is unloaded; and, wherein said first axle assembly, said second axle assembly, and said third axle assembly provide substantially equal support to said vehicle when loaded.
