Abstract

An electrical axle drive device includes at least one first electrical machine, which has a stator and a rotor rotatable around a machine axis of rotation relative to the stator. A gear unit is drivable by the first electrical machine having at least one first planetary gear stage drivable by the first electrical machine and at least one first spur gear stage drivable by the first electrical machine. The device also includes at least one drive wheel of the motor vehicle being able to be rotated around a wheel axis of rotation running parallel to the machine axis of rotation and being drivable by the first electrical machine via the gear unit. The first electrical machine is arranged at least partially on a first side of the longitudinal central plane with respect to a longitudinal central plane of the vehicle that is spanned by the vehicle vertical direction and the vehicle longitudinal direction and the first spur gear stage is arranged on a second side of the longitudinal central plane opposite the first side in the vehicle transverse direction.
