Abstract
Abstract A torsion bar suspension system for vehicles, especially those used for transporting delicate cargo or cargo over rough surfaces. The four independently suspended wheels are mounted on lever arms and torsion bars. The two torsion bars on each side are connected to a deformable parallelogram so that upward movement of one wheel will exert a downward force on the other.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
113 words
A torsion bar suspension system comprising a plurality of wheel means, a plurality of torsion bars each supporting a lever and wheel means at one end and being secured to a block at the other end, bearing means rotatably supporting each of said torsion bars at said one end, the other end of each of said torsion bars being unsupported, and means interconnecting the blocks associated with the wheels on one side of a vehicle to constitute a deformable parallelogram, said levers being mounted in opposite senses so that a movement in one wheel means tends to cause an opposite movement in the other wheel means on the same side of the vehicle.
Claim 2
Dependent Claim
