1. An electric axle comprising:
a first axial flux electric motor coupled to a first drive wheel via a first gear set;
a second axial flux electric motor coupled to a second drive wheel via second gear set; and
a locking clutch designed to selectively lock rotation of a first rotor shaft and a second rotor shaft in the first and second axial flux electric motors, respectively;
wherein each of the first axial flux electric motor and the second axial flux electric motor include rotor sections position on opposing axial sides of a stator; and
wherein the first and second splined interfaces are coupled to the first and second rotor shafts on inboard sides of the first and second electric machines and a first and second gear sets are coupled to the first and second rotor shafts, respectively, on outboard sides of the first and second electric machines.
