OVER-RUNNING CLUTCH PULLEY WITH SLIP INFLUENCE

摘要

The over-running clutch pulley (10) of a preferred embodiment of the invention includes a sheave member (20), a hub member (22) located substantially concentrically within the sheave member, a clutch member (24), and slip influencing means (26), which cooperate to rotationally engage an input device (12) and an output device (14). The sheave member preferably includes a sheave input section (28) adapted to engage the input device, and a sheave clutch section (30) defining a sheave clutch surface. Similarly, the hub member preferably includes a hub output section (34) adapted to engage the output device, and a hub clutch section (36) defining a hub clutch surface. In the preferred embodiment, the slip influencing means influences the clutch member to remain substantially engaged to the hub clutch surface and to slip against the sheave clutch surface upon the deceleration of the sheave member in the first rotational direction relative the hub member.
