Abstract:
Methods and systems are provided for an electric axle assembly having dual motors and dual disconnects allowing for selectably disconnecting either one of the motors so that either motor may operate as the primary drive motor. In one example, an electric axle assembly comprises: a first motor in communication with a first shaft; a second motor in communication with a second shaft; a first gear set operably coupled to the first shaft; a second gear set operably coupled to the second shaft; and a clutch assembly selectively coupled to the first gear set and the second gear set and operably coupled to an output shaft, wherein the clutch assembly comprises a shift collar and a shift fork, the clutch assembly having a first configuration, a second configuration, and a third configuration, wherein in the first configuration the first motor and the second motor are coupled to the output shaft, in the second configuration the first motor is coupled to the output shaft, and in the third configuration the second motor is coupled to the output shaft.
