Abstract

An electric axle drive for a motor vehicle includes at least one electric motor, a differential transmission drivable by the electric motor, a first housing part that at least partially surrounds the differential transmission, a second housing part formed separately from the first housing part and at least partially surrounding the electric motor, and a third housing part formed separately from the first and second housing parts. The first and second housing parts are directly connected to each other by a first flange connection. The second and third housing parts are directly connected to each other by a third flange connection. The third housing part is designed to at least partially support a sub-transmission for connecting the differential transmission to the electric motor. The first and third housing parts are directly connected to each other by a second flange connection.
