摘要

A motorized hub (1) for an electric traction automobile vehicle, said motorized hub comprising a hub (9) adapted to receive a wheel (2), the hub being mounted to rotate relative to a hub-carrier (7) about a hub axis. The motorized hub comprises a traction electric machine having an external stator (32) fastened to the hub-carrier and an internal rotor (31) the rotation axis of which is spaced from the hub axis and parallel to said hub axis. The motorized hub comprises reduction means (6) operating between the rotor of the electric machine and the hub, and friction braking means, the brake rotor (5) being fastened to the hub and disposed axially on the vehicle interior side relative to the reduction means. The shaft of the rotor (31) of the electric machine being placed radially outside the brake rotor and extending axially from the reduction means toward the interior of the vehicle.
