Abstract:
An electric powertrain includes a first electric motor that has an uninterrupted connection with a drive shaft of a vehicle. The electric powertrain further includes a first gear train that has an interruptible connection with the drive shaft. In one form, this interruptible connection includes a second carrier and a clutch engagement member. The electric powertrain further includes a sun gear in the form of a ring gear and planet gears in the form of a first output shaft. To provide a compact configuration, the first electric motor and the first gear train are sandwiched between the sun gear and the planet gears.
