On the oustide of the vehicle, the hub (12) supports a rim (30) bearing a wheel (32) of the vehicle and a ventilated brake disc (34) housed substantially inside the rim (30), substantially radial ventilating ducts (36) being arranged in the thickness of said disc. The invention is characterised in that the hub (12) includes at least one bore (44) that opens to the exterior and communicates with the radial ventilating ducts (36) of the disc (34) by means of radial channels (46).
