WHEEL DEVICE WITH INTEGRATED ELECTRIC MOTOR FOR A MOTOR VEHICLE

A wheel device (4) for a motor vehicle (1) includes a rim (5) having an axis (H) and an outer surface (6) defining a seat (7) for fitting a tyre (8), a wheel hub (9) arranged around the axis (H) inside the rim (5) and suited to be coupled to a suspension of the motor vehicle (1), an electric motor (10) comprising a stator (11) arranged coaxially to the wheel hub (9) in a fixed position relative to the wheel hub (9) and a rotor (12) configured to interact magnetically with the stator (11), a radial bearing (13) supporting the rotor (12) in a rotary manner around said axis (H) relative to the wheel hub (9) and to the stator (11), a flange (5a) fixed relative to the rim (5) and arranged inside the rim (5) in a radially projecting manner relative to the rim (5) towards said axis (H), and releasable fixing means to fix the rotor (12) to the flange (5a).
