    Abstract: An electric drive-unit encased in a housing includes an electric motor, a first output member, and a second output member. The drive-unit also includes first, second, and third planetary gear-sets, each having first, second, and third nodes. The first gear-set has one node connected to the electric motor. The second gear-set has one node connected to the first planetary gear-set, another node connected to the first output member, and the remaining node fixed to the housing. The third gear-set has one node connected to the first gear-set and another node connected to the second output member. The drive-unit additionally includes a first torque-transmitting device configured to selectively connect one third gear-set node to the housing to thereby affect a first speed-ratio. Furthermore, the drive-unit includes a second torque-transmitting device configured to selectively connect one first gear-set node to one of the third gear-set nodes to thereby affect a second speed-ratio.

    Abstract: A mechanical clutch such as a dog clutch includes a plurality of balls or rollers disposed in a carrier and positioned between opposed sets of straight cut teeth extending from opposed drive and driven elements. A ball or roller is positioned between each adjacent pair of teeth such that the torque load is transferred from the tooth on a first or drive element, through the ball or roller, to an adjacent projection or tooth on a second or driven element. The balls or rollers are maintained in position by the carrier having an inner ring and a concentric outer ring. Greatly reduced disengagement force, even under load, is exhibited by a clutch of this configuration.

    Abstract: A transmission includes a single planetary gearset, a first torque machine, an output member and a two-speed gearset that is coupled to the drive member. The single planetary gearset includes a sun gear, a carrier gearset and a ring gear, wherein the carrier gearset is rotatably couplable to the input member and rotatably couplable to the output member, the sun gear is rotatably coupled to a rotor of the first torque machine, and the ring gear is rotatably couplable to the input member and rotatably couplable to the output member. The output member is rotatably couplable to the two-speed gearset, which is configured to operate in one of a first gear ratio and a second gear ratio.

    Abstract: A powertrain for a vehicle includes an engine and a method of assembling the powertrain includes providing the engine. A starter mechanism is selectively operable to start the engine. A motor-generator includes an adapter to dispose the motor-generator and the starter mechanism in alternative assembly configurations being a first assembly configuration and a second assembly configuration. The first assembly configuration is when the starter mechanism is coupleable to the adapter to selectively transfer torque from the motor-generator through the adapter and the starter mechanism to start the engine. The second assembly configuration is when the starter mechanism is spaced from the adapter to operate independently of the motor-generator such that the starter mechanism selectively transfers torque to start the engine.
