Abstract
Motorized hub for an electrically powered motor vehicle comprising a wheel hub mounted to rotate about a hub axis, and an electric traction unit comprising an external stator connected to a hub carrier and an internal rotor () whose axis of rotation is distant from the hub axis. The motorized hub comprises reduction means acting between shaft () of rotor (), friction braking means, and a braking rotor secured to the hub. The reduction means comprise a drive pinion connected to the rotor () and a ring gear connected to the hub. A brake shaft passes through the hub carrier to connect the braking rotor to the hub. The reduction means comprise two reduction stages and the hub is mounted so that it can rotate via rolling-contact hub bearings positioned around a stub axle of the hub carrier, the brake shaft passing axially through a cavity of the stub axle.
