ABSTRACT:
An improved coupling component includes an annular tube which is inflatable to move friction shoe assemblies into engagement with another component of a coupling. Elastomeric mounting material is connected with the tube and is molded in place against the friction shoe assemblies. The molded elastomeric mounting material extends around torque transmitting elements, such as pins, connected with backing plate of the friction shoe assemblies to connect the elastomeric mounting material with the friction shoe assemblies. When the coupling component is to be constructed, the tube and a plurality of friction shoe assemblies are placed in a mold. The tube is then expanded under the influence of fluid pressure to press elastomeric mounting material against the friction shoe assemblies. Upon application of heat, the elastomeric mounting material is molded around torque transmitting elements connected with the friction shoe assemblies.
