摘要： Various pulley assemblies are described that include a pulley body, a hub defining an axis of rotation disposed within a bore of the pulley body, and an actuator and a clutch mechanism disposed about the hub. The actuator axially expands when the pulley body rotates in a predominant direction, and the clutch mechanism is activated thereby into an engaged position. In this engaged position, the clutch mechanism links the pulley body to the hub for simultaneous rotation in the predominant direction. Then, when the pulley body rotates in a non-dominant direction or experiences a deceleration, the pulley assembly enters an overrun position where the clutch mechanism disengages and allows the hub to rotate at speeds greater than the pulley body. Additionally, a reverse configuration is described where the actuator axially expands when the hub rotates and the clutch mechanism, when engaged, links the hub to the pulley body.
