Abstract

A tubular torsion bar including an elongated inner tube of flexible material having a proximal end and a distal end, an elongated outer tube of flexible material having a proximal end and a distal end, a cylindrically shaped joiner bushing fixedly attached to and positioned partially between the distal end of the inner tube and the distal end of the outer tube with the inner tube and outer tube positioned in coaxial and substantially coextensive concentric nesting positions, external apparatus mounting the joiner bushing to maintain axial alignment of the distal and proximal ends of the inner tube and the outer tube and for limited rotational movement, and a mounting and output system fixedly attached to the proximal ends of the inner tube and the outer tube.
