Zusammenfassung:	An electric axle assembly includes an electric motor having an output shaft. A two stage gear train is coupled with the output shaft. The two stage gear train includes two reduction gears which provide different gear ratios. A differential is provided. A hollow differential input shaft is splined with the differential wherein the hollow input shaft supports driven gears that rotate independently relative to the hollow differential input shaft. A sliding dog clutch is splined to the hollow differential input shaft selectively engaging the driven gears or maintaining a neutral position wherein the electric motor and gear train are disconnected from the differential.
