Abstract: An end attachment assembly for a twisted rope torsion bar includes an anchor nut and a plurality of strap wrenches. A plurality of tie rods and a washer secure the assembly and transmit the torque. The torison bar is preferably fabricated of a lightweight glass fiber/epoxy composite material formed in a rope. In operation, the application of torque to the anchor nut results in a rotating/pivoting action by the strap wrenches. The strap associated with each strap wrench loops around the torsion bar and overlaps itself in the area of engagement with a cross bar that forms a cam. As the cross bar rotates/pivots and presses against the engaging portion of the strap, the strap firmly grips the torsion rod. The strap resists by frictional engagement any sliding motion over the torsion bar and against itself in the overlapping region. This compressive action adjusts for the diametral change of the torsion bar upon the application of torque and results in a tighter and tighter grip to the torsion bar.
