Abstract
A coaxial electrified drive axle is provided for a vehicle. The coaxial electrified drive axle has an electric motor connected to a gear box housing containing a stepped planetary gear set operatively coupling a drive shaft of the electric motor to a linkshaft and an output shaft through a differential assembly. The differential assembly is contained within a carrier which also supports the planet gears through planet pins. The carrier is supported by a single carrier support bearing. The drive shaft, the linkshaft, and the output shaft are coaxial and share a common axis of rotation.
