  • Patent number: 11879529
    Abstract: A two-speed gearbox assembly for an electric drive vehicle includes a housing, a first planetary gear set configured to operably connect to an output of an electric motor to drive a first axle, the first planetary gear set including a first sun gear, a first carrier, and a first ring gear, a first clutch configured to selectively ground the first ring gear, and a second clutch configured to selectively ground the first carrier. A second planetary gear set is configured to operably connect to the output of the electric motor to drive a second axle, the second planetary gear set including a second sun gear, a second carrier, and a second ring gear. A third clutch is configured to selectively ground the second ring gear, and a fourth clutch is configured to selectively ground the second carrier. The first, second, third, and fourth clutches are independently controlled.

  • Patent number: 10160314
    Abstract: A vehicle with a primary driveline that is configured to distribute rotary power to a first set of vehicle wheels and a power transmitting device that can be selectively operated to transmit rotary power to a secondary driveline. The power transmitting device has an input member, which is driven by the primary driveline, and an output member that is selectively coupled to the input member to receive rotary power therefrom. The secondary driveline comprises a differential, a pair of shafts, and a side shaft coupling that selectively interrupts power transmission between the differential and one of the shafts.

  • Patent number: 8712651
    Abstract: A method of operating a multi-mode drive system that precisely orchestrates a shift between gear ratios in a power take off unit and a rear drive module. The method first shifts between gear ratios in the power take off unit and then, depending upon the success or failure of the shift of the power take off unit, shifts between gear ratios in the rear drive module.

  • Patent number: 5806371
    Abstract: An automotive differential has two annular housing parts that are screwed together and an adjustment collar that is screwed into one of the annular housing parts. A ring gear is supported by bearings in the respective housing parts for rotation on a longitudinal axis that is perpendicular to a plane through the juncture of the two annular housing parts. A pinion gear is also rotatably mounted in the annular housing part that carries the adjustment collar for rotation on an axis that is not parallel to the longitudinal axis of the ring gear. The pinion gear meshes with the ring gear. Gear backlash and bearing preload are adjusted by indexing the two housing parts with respect to each other and by positioning the adjustment collar with respect to the one housing part.
