Abstract
Methods and systems are provided for an electric axle. The electric axle system includes, in one example, a first electric machine and a planetary reduction differential configured to receive mechanical power from the first electric machine. The planetary reduction differential includes a first planetary gear set directly rotationally coupled to a second planetary gear set. In the electric axle system, a sun gear in the first planetary gear set is directly coupled to an input shaft of the planetary reduction differential.
