  • INTEGRATED SWITCHABLE SHAFT BEARING
    Publication number: 20150027843
    Abstract: An integrated switchable shaft bearing having an inner ring, a circumferentially extending clutch groove, and axially extending cam pin openings. An outer ring is located about the inner ring, and rolling elements are located therebetween. A clutch ring with clutch fingers is located in the clutch groove. Cam pins are located in pin openings and extend beneath the clutch fingers. An actuator moves the cam pins from an engaged position, where cam portions each engage a respective one of the clutch fingers forcing it outwardly above a race surface of the inner ring into engagement with the rolling elements to transfer torque from the outer ring to the inner ring, to a released position, in which cam pins are disengaged from the clutch fingers, which move beneath the race surface of the inner ring so that the outer ring is rotatable relative to the inner ring via the rolling elements.
