ABSTRACT:
An end attachment assembly for a twisted rope torsion bar includes an anchor nut and an internal elastomeric bushing cooperatively mating with the nut. The elastomeric bushing is molded onto the end of the twisted rope torsion bar. The torsion bar is fabricated of a lightweight glass fiber/epoxy composite material. The elastomeric bushing has external splines cooperating and mating with splines on the inner bore of the anchor nut. The end attachment assembly compresses the end of the twisted rope torsion bar to reduce stress concentration and prevent separation, i.e. the application of torque to the anchor nut transmits a like amount of torque to the elastomeric bushing to compress and more firmly grip the twisted rope torsion bar. The elastomeric bushing is compressed radially inwardly by the cam shape of the mating splines. Advantageously, the elastomeric bushing proportionally increases the grip on the end of the torsion bar so that the joint is made tighter and tighter under increased torque.
