ABSTRACT:
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 or a non-circular portion of the axle 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 hydraulic winch cable and spool provide for pre-rotating the one shaft or the axle tube to lower and raise the vehicle.
