Abstract: A power transferring gearset includes a gear synchronization controller disposed in communication with a drive gear, a driven gear and a shifting mechanism. In response to detecting a gear engagement command, the gear synchronization controller is configured to determine a rotational speed delta between a rotational speed of the drive gear and a rotational speed of the driven gear and compare the rotational speed delta to a pre-determined speed delta. In response to determining that the rotational speed delta is less than the predetermined speed delta, the gear synchronization controller applies a rotational shutter function to the drive gear to apply a series of clockwise and counterclockwise rotational cycles to the drive gear simultaneously during the axial movement of the shifting mechanism for preventing a blocked condition of the power transferring gearset while establishing the meshed relationship between the shifting and gear teeth.

Abstract: 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.
