Abstract:
An over-running clutch pulley for rotationally engaging an input device and an output device, comprising:a sheave member including a sheave input section adapted to engage the input device, and a sheave clutch section defining a sheave clutch surface; a hub member located substantially concentrically within said sheave member and including a hub output section adapted to engage the output device, and a hub clutch section defining a hub clutch surface substantially adjacent said sheave clutch surface; a spring member adapted to lock against said sheave clutch surface and said hub clutch surface thereby engaging said sheave clutch surface and said hub clutch surface upon the acceleration of said sheave member in a first rotational direction relative said hub member, and to slip against one of said sheave clutch surface and said hub clutch surface thereby disengaging said sheave clutch surface and said hub clutch surface upon the deceleration of said sheave member in the first rotational direction relative said hub member; and a stop surface adapted to engage said spring member upon the acceleration of said sheave member in the first rotational direction relative said hub member and adapted to slip over said spring member upon the rotation of said sheave member relative to said hub member in a second rotational direction opposite the first rotational direction.
