<p>A clutch for engaging a driving member (10) with a driven member (20) automatically upon application of torque to rotate the driving member in either direction, for maintaining engagement in either the drive or coast mode of operation and during the transition between drive and coast, for maintaining engagement in either forward or reverse operation and during the transition between forward and reverse, and for disengaging automatically upon interruption of the torque and slight rotation in the opposite direction. The clutch includes a mechanism(42-60-76) for developing high frictional drag upon initial rotation of the driving member to effect clutch engagement, and low frictional drag thereafter to conserve power.</p> |
