Claim:
A suspension system for vehicle having a frame with a top and an underside, and two sides, the suspension system comprising a. at least one pair of axles with one axle of each pair disposed on each side of the vehicle, each axle having— i. a shaft with a first portion having an inner end and an outer end, ii. an arm connected to the outer end and projecting tangentially therefrom to a terminal end, the arm located outside of the vehicle frame, and iii. a spindle affixed to the terminal end of each arm and adapted to engage a wheel; b. a rotational attachment means for affixing each axle to the underside and for allowing it to rotate relative thereto, c. at least one axle retainer adapted to prevent lateral movement of each axle; d. a torsion means for resisting rotation of each axle in response to a load supported by each axle; and e. at least one limiter to limit rotation of each axle relative to the frame, whereby, application of a load biases the axle against the torsion means which supports the frame and absorbs shocks created by motion of the vehicle over uneven surfaces.
