Abstract
A drive module that includes an electric motor, an input pinion driven by the electric motor, a transmission driven by the input pinion, a planetary differential assembly and first and second axle shafts. The transmission has a first transmission output member. The planetary differential assembly has an input ring gear, a first output sun gear and a second output sun gear. The first and second output sun gears have different pitch diameters, different modules and a common quantity of sun gear teeth. The planetary differential assembly is configured to provide a 50-50 torque split between the first and second output sun gears. The first axle shaft is coupled to the first output sun gear for rotation therewith. The second axle shaft is coupled to the second output sun gear for rotation therewith.
