A torsion axle for a vehicle includes an elongated axle tube enclosing first stage torsion shafts and second stage torsion shafts all having a common axis, and a metal tube and a plurality of resilient rubber rods confine each of the shafts for torsionally resisting rotation of the shaft. Each first stage metal tube is secured to the surrounding axle tube, and each second stage metal tube is connected to the corresponding first stage shaft. A stud projects outwardly from each second stage metal tube through a slot within the surrounding axle tube to limit rotation of the second stage tube with the first stage shaft, and a crank arm and eccentric spindle are secured to the outer end portion of each second stage shaft for receiving a wheel. In modifications, the first stage shafts for both the left and right wheels are connected as one shaft, and a winch cable and spool provide for prerotating the one shaft to lower the vehicle for convenient loading.
A multiple stage torsion axle adapted for use on a trailer or other vehicle, comprising an elongated axle tube having a center axis, means for mounting said axle tube on the vehicle, a first stage torsion shaft and a second stage torsion shaft disposed within said axle tube, first stage torsion means including a resilient rubber-like material and connected for torsionally resisting rotation of said first stage torsion shaft relative to said axle tube, second stage torsion means including a resilient rubber-like material and connected for torsionally resisting rotation of said second stage torsion shaft relative to said first stage torsion shaft, and a crank arm connected to said second stage torsion shaft and having eccentric means for attaching a wheel.
A multiple stage torsion axle adapted for use on a trailer or other vehicle, comprising an elongated axle tube having a center axis, means for mounting said axle tube on the vehicle, a first stage torsion shaft and a second stage torsion shaft disposed within said axle tube in axial alignment, a rigid torsion tube section and a plurality of rubber-like resilient rods confining each of said shafts with said rods disposed between said shaft and said torsion tube section for torsionally resisting rotation of said shaft relative to said torsion tube section means for connecting said torsion tube section confining said first stage torsion shaft to said axle tube, means for connecting said torsion tube section confirming said second stage torsion shaft to said first stage torsion shaft, and a crank arm connected to said second stage torsion shaft and having eccentric means for attaching a wheel.
A multiple stage torsion axle adapted for use on a trailer or other vehicle, comprising an elongated axle tube having a center axis, means for mounting said axle tube on the vehicle, a pair of first stage torsion shafts and a pair of second stage torsion shafts disposed in said axle tube within corresponding first stage and second stage rigid torsion tube sections, a plurality of resilient rubber-like rods disposed between each said torsion shaft and the corresponding said torsion tube section for torsionally resisting rotation of each said torsion shaft relative to the corresponding torsion tube section, means for connecting said first stage torsion tube sections to said axle tube, means for connecting said second stage torsion tube sections to said first stage torsion shafts, and a crank arm connected to each said second stage torsion shaft and having eccentric means for attaching a wheel.
