Abstract
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. Each of the dual motors is coupled to a layshaft, and each disconnect is positioned between a gear reduction at the output of the motor and a gear reduction connected to the layshaft. The layshaft is coupled to a differential via a clutch and gear set, the gear set providing a two-speed transmission for power delivered from the layshaft to the differential.
