Abstract
The over-running clutch pulley of a preferred embodiment of the invention includes a sheave member, a hub member located substantially concentrically within the sheave member, a spring member, and a stop surface, which cooperate to rotationally engage an input device and an output device. The sheave member preferably includes a sheave input section adapted to the engage the input device, and a sheave clutch section defining a sheave clutch surface. Similarly, the hub member preferably includes a hub output section adapted to engage the output device, and a hub clutch section defining a hub clutch surface. The stop surface functions to engage the spring member and to transfer some torque from the sheave member to the hub member during the acceleration of the sheave member in the first rotational direction relative the hub member.
