Abstract
A linear or longitudinal torsion axle where the torsion shaft extends parallel to the longitudinal extent of the vehicle to which the torsion axle is attached. The torsion axle includes two torsion assemblies with the torsion shaft extending into and being supported by both torsion assemblies. Each torsion assembly has a housing enclosing a plurality of resilient torsion rods spaced about the outside of the torsion shaft. The torsion shaft is fixed to a wishbone connector that is positioned between the two torsion assemblies. A wheel spindle is fixed to an outer end of the wishbone connector to accept a wheel and tire assembly.
Claims30
A torsion axle comprising:
- a shaft;
- at least one torsion assembly, the shaft extending into and being supported by the at least one torsion assembly;
- a connecting arm being fixed to the shaft;
- and
- a wheel spindle pivotally connected to an end of the connecting arm distal the shaft, the wheel spindle having an axis 90° to the axis of the shaft.
A torsion axle comprising:
- a shaft;
- two spaced apart torsion assemblies, the shaft extending into and being supported by the torsion assemblies, each torsion assembly having:
- a housing adapted to be attached to a vehicle;
- and a plurality of resilient rods within the housing, the resilient rods being spaced about an outer periphery of the shaft, the resilient rods extending co-linearly with the shaft, the shaft being configured to engage the resilient rods, whereby the resilient rods resist rotation of the shaft;
- a wishbone connecting arm positioned between the torsion assemblies and being fixed to the shaft;
- and
- a wheel spindle pivotally connected to an end of the wishbone connecting arm distal the shaft, the wheel spindle having an axis 90° to the axis of the shaft.
A torsion axle for use with a vehicle, the vehicle having a longitudinal dimension extending from front to back and a transverse dimension extending from side to side, the torsion axle comprising:
- a longitudinally extending torsion shaft;
- at least one torsion assembly, the torsion shaft extending into and being supported by the at least one torsion assembly, the torsion assembly comprising:
- a housing adapted to be attached to the vehicle;
- and a plurality of longitudinally extending resilient rods within the housing, the resilient rods being spaced about an outer periphery of the torsion shaft, the torsion shaft being configured to engage the resilient rods whereby the resilient rods resist rotation of the torsion shaft.
In a trailer having a floor and a plurality of sides, the trailer having a longitudinal dimension extending from front to back and a transverse dimension extending from side to side, a torsion axle comprising:
- a longitudinally extending torsion shaft;
- two spaced apart torsion assemblies;
- and
- a connecting arm positioned between the torsion assemblies, the torsion shaft being fixed to the connecting arm.
