Abstract:
An electric drive axle assembly of a vehicle includes an electric motor having an output shaft. At least one of a gear and a planetary gear assembly is coupled to the output shaft of the electric motor. The at least one of the gear and the planetary gear assembly is coupled to a differential mechanism configured to transfer torque to two axle shafts of the vehicle. The electric drive axle assembly configured to produce a plurality of speed ratios between the electric motor and the differential mechanism.
