Abstract
An electric axle assembly is disclosed. The electric axle assembly includes a common housing with an electric motor, a continuously variable transmission, and a planetary differential. The electric motor includes an output shaft and the continuously variable transmission is connected to the output shaft. The continuously variable transmission includes a drive shaft configured to be variably driven by the output shaft. The planetary differential is connected to the drive shaft, and the planetary differential includes a carrier configured to be driven by the drive shaft and dual sun gears configured to be driven by the carrier. Wheel axles are in independent driving engagement with a respective one of the dual sun gears.
