A transmission mechanism is provided with an output gear drivingly coupled to at least one of a pair of output members and placed coaxially with the pair of output members. A direction in which a rotating electrical machine and an inverter device are arranged side by side in an axial view is defined as a first direction. A direction perpendicular to both an axial direction and the first direction is defined as a second direction. A first output member that is one of the pair of output members is placed between the rotating electrical machine and the inverter device in the first direction, at a position in the second direction where both the rotating electrical machine and the inverter device are placed. The output gear is placed in such a manner as to overlap each of the rotating electrical machine and the inverter device in the axial view.

Methods and systems for an epicyclic gear mechanism that includes a primary differential assembly to selectively drive the fore secondary differential assembly and the aft secondary differential assembly. The fore secondary differential assembly selectively drives one or more fore interfaces (e.g., output gears), whereas the aft secondary differential assembly selectively drives one or more aft interfaces (e.g., output gears). Each of the primary differential assembly, the fore and aft secondary differential assemblies, and the interfaces rotate about a common central axis. The primary differential assembly drives the fore secondary differential assembly via a first sun gear, and drives the aft secondary differential assembly via a second sun gear, both of which rotate about the common central axis. Further, one or more actuators are to activate or deactivate in order to drive or be driven by a selected interface.

The differential thereby comprises a first gear connected to the first output member, a second gear connected to the second output member, and at least one third gear system comprising gears and freewheel gears.
