An e-axle assembly includes a housing extending from a first housing end to a second housing end to define an internal compartment. At least one electric motor is disposed in the internal compartment and includes a stator and a rotor rotatable relative to the stator about an axis. The rotor defines a hollow extending internally within the rotor, and at least one of a gearing mechanism, a shifting actuator, and/or a differential is disposed within the hollow (and thus packaged within the rotor). In a preferred arrangement, all and any of the gearing mechanisms, shifting actuators, and differential are disposed within the hollow of the rotor. This internal packaging of the drive components within the rotor reduces an overall space and weight of the e-axle assembly relative to the prior art designs to more easily and readily achieve the smaller space and weight allotments afforded by electric and/or hybrid vehicles.

Compact E-axle assembly

A lubricant supported electric motor assembly includes an electric motor module, a shifting and first stage module, and a final drive module sequentially operably interconnected with one another for producing drive torque that is ultimately conducted to a wheel of a vehicle. The electric motor module includes a stator and a rotor defining an internal rotor cavity. The shifting and first stage module is disposed within the internal rotor cavity and includes a first planetary gear reducer assembly and an output gear selectively coupleable to said first planetary gear reducer assembly. The final drive module is disposed adjacent the shifting and first stage module and includes a second planetary gear reducer assembly operably coupled with the output gear. A shifting mechanism establishes selective coupling between the first planetary gear assembly and the output gear to transfer adjustable torque from the shifting and first stage module to the final drive device.
