Wheel hub adapted to control a pressure of one respective tyre comprising a spindle (F) having a longitudinal shape on which a bearing (B) is keyed having a fixed part (BF) with the spindle and a rotating part (BB), rotatably associated to the fixed part (BF), and a wheel disc (RD) adapted to be connected to a vehicular wheel. The wheel disc is associated to the rotating part (BB) of the bearing, wherein the spindle (F) comprises an end portion (S3) on which a central part (RDC) of the wheel disc (RD) is adapted to be engaged and a gasket (G) is interposed annularly between the end portion (S3) and the central part (RDC) to define a sealed head rotating chamber (C1), and wherein the spindle (F) comprises a first channel (CH1) having a first end which flows into the head rotating chamber (C1) and a second end (CN2) adapted to be pneumatically connected to a compressed air source, and wherein the central part (RDC) comprises a first opening (CN1) adapted to be pneumatically connected to a valve of a tyre of the vehicular wheel. |
