ABSTRACT:
A fluid operated coupling which includes an inflatable annular tube element of an elastomeric material moves a plurality of aligned friction shoes in a radial direction to effect a torque sustaining clutching or braking engagement. A thermal barrier is provided to retard the transfer of heat from the friction shoes to the annular tube element. The thermal barrier protects the tube element and adds mechanical strength thereto to prevent excessive elongation and extrusion of the tube element between the plurality of friction shoes when the tube element is expanded. The thermal barrier is at least partially imbedded in the exterior surface of the tube element.
