ABSTRACT:
Pilot torque is transmitted from the input member to the output member of a clutch when a shoe is pressed axially against the input member. When initially turned by the input member, the shoe causes a helical spring to wrap down on angularly spaced shoe segments and to contract the shoe segments into radial gripping engagement with the input member. The shoe segments engage angularly spaced drive lugs on the output member to transmit torque to the output member.
