<p>CLUTCH HAVING SEGMENTED BAND An electromechanical clutch for vehicle engine cooling fans includes a driving member mounted for rotation by the vehicle engine and a driven member carrying the engine fan and rotatably mounted on the driving member. The driven and driving members cooperate to define a circumferentially extending gap therebetween. The driving member carries an electrical coil, which is energized when the clutch is to be engaged. A band is disposed within the gap, includes an outer band member which carries a frictional material that is adapted to frictionally engage the driven member and an inner band member which is adapted to engage the driving member when the coil is actuated. The inner and outer members are connected at corresponding ends thereof. The inner member comprises arcuate segments of electromagnetic material and joining segments which interconnects the arcuate segments. The joining segment is made from a relatively flexible, resilient material to permit relative radial movement between the arcuate segments, thereby permitting the arcuate segments to flex relative to one another when the coil is energized.</p> |
