Patent ID: 8387767

Claim:
A clutched device comprising: a clutch assembly comprising a first rotary clutch portion, a second rotary clutch portion, a drive member, a wrap spring and an actuator, the first and second rotary clutch portions being rotatably disposed about a rotary axis of the clutched device, the drive member being disposed about the rotary axis and having an interior clutch surface, the wrap spring having a first end, a second end and a plurality of helical coils that extend axially between the first and second ends, the first end being fixed to the first rotary clutch portion, the second end contacting the second rotary clutch portion, the helical coils being received against the interior clutch surface, the actuator comprising an actuator member that is coupled to the first rotary clutch portion for rotation therewith, the actuator member being axially movable along the rotary axis between a first position and a second position to control rotary drag forces within the clutch assembly to effect engagement and disengagement, respectively, of the clutch assembly; wherein at least a portion of the rotary power input to the wrap spring is transmitted through an axial end face of the second end of the wrap spring and into a surface of the second rotary clutch portion against which the axial end face of the second end is abutted; and wherein the actuator member is rotationally coupled to a teaser, the teaser being frictionally engaged to the drive member when the actuator member is in the first position.
