ABSTRACT:
The tie-bar (10) comprises a pair of spaced-apart bushings (12, 14) each having end flanges (16) extending from a central cylindrical portion and a through opening (18) for connecting to flexing structures. A plurality of wires (20) comprises bands (22) of parallel wires (20) wrapped endlessly about the spaced-apart bushings (12, 14) provide a tie-bar (10) having bushings (12, 14) disposed at the ends and connected by a pair of spaced-apart side portions (24) of superimposed bands (22). The wires (20) are coated with a dry film lubricant so that the wires (20) are dry wrapped about the bushings (12, 14), and then a resin material (23) encapsulated about the dry wrapped wire bands (22) and bushings (12, 14). A body (26) of resin material disposed between the spaced-apart side portions (24) and the bushings (12, 14) maintains the spaced-apart relationship of the bushings (12, 14) by withstanding the compressive tension of the tightly wrapped wires (20). The wires (20) are free to move relative to one another in response to tension and torsional forces exerted upon the tie-bar (10).
