Abstract: A transfer case for use in a vehicle, with the vehicle including a powertrain, includes an input shaft configured to be rotatably coupled to the powertrain. The transfer case also includes a primary output shaft rotatably coupled to the input shaft, and a secondary output shaft selectively rotatably coupled to the primary output shaft. The transfer case further includes a planetary gearset disposed between and rotatably coupled to the input shaft and the primary output shaft. The transfer case also includes an input member and an electric machine. The input member is rotatably coupled to the electric machine and the input shaft to provide rotational torque from the electric machine, to the input shaft, and to the primary output shaft.

Abstract: A transmission system includes a transmission housing and a countershaft having no less than two gears, with the gears defining a plurality of gear ratios. The transmission system also includes a module housing, a first output shaft rotatably coupled to the countershaft, and a second output shaft rotatably coupled to the countershaft. The transmission system further includes a first clutch configured to selectively rotatably couple the first output shaft to the countershaft. The transmission system also includes a second clutch configured to selectively rotatably couple the second output shaft to the countershaft. The transmission system further includes an electric machine configured to deliver rotational power to at least one of the first and second output shafts to deliver rotational power to the countershaft. The countershaft is rotatably coupled to either of the first and second output shafts for all of the gear ratios.

Abstract: An assembly for an electric vehicle includes an input shaft extending along a first axis and an electric motor rotatably coupled to the input shaft and co-axially aligned with the first axis. The assembly also includes an intermediate input shaft extending along a second axis and rotatably coupled to the input shaft. The assembly also includes an output shaft extending along the second axis and spaced from the intermediate input shaft along the second axis. The assembly further includes a planetary gearset rotatably coupled to the intermediate input shaft and to the output shaft, and co-axially aligned with the second axis. The assembly includes a final drive co-axially aligned with the first axis and rotatably coupled to the output shaft for providing rotational torque to at least one of a first and second set of wheels of the electric vehicle.

Abstract: A transmission system includes an input shaft, a transmission housing, and a planetary gear system rotatably coupled to the input shaft. The planetary gear system has a first and second gear ratio. The transmission system additionally includes an output shaft, a first electric machine, a second electric machine, and a shifting assembly. The shifting assembly includes a first stationary clutch element and a second stationary clutch element. The first electric machine is configured to apply rotational torque to the planetary gear system to synchronize rotational speed of the planetary gear system when moving between the first and second gear ratios, and the second electric machine is configured to provide rotational torque to the output shaft when the first electric machine applies rotational torque to the planetary gear system to synchronize rotational speed of the planetary gear system when moving between the first and second gear ratio.
