  • Patent number: 6652405
    Abstract: A multi-speed wheel hub includes a sun gear engagement clutch and a housing engagement clutch. A single shift ring is coupled to and rotates with the input member. The shift ring is positioned between the sun gear engagement clutch and the housing engagement clutch. The shift ring is axially movable along the input member. Upon movement of the shift ring in a first direction, a first engagement clutch of the shift ring engages the sun gear engagement clutch so that torque from the input member is transmitted by the shift ring to the sun gear through a planet carrier and a ring gear to the housing. Upon movement of the shift ring in a second direction a second engagement clutch of the shift ring engages the housing engagement clutch so that torque from the input member is transmitted by the shift ring directly to the housing.
