A vehicle non-driving wheel hub mounting equipped with a pulse-transmitter and sensor assembly comprises an integral rolling bearing (1, 2, 11, 12) with two rows of rolling elements (1). The active parts (16, 17) of the pulse transmitter and the sensor (18) are accommodated and positioned inside a volume delimited radially by the cylindrical inner surface (10) of a tubular protuberance (7). The protuberance also centers the brake disc (5) or drum and the wheel (6). The volume is delimited axially in one direction by a plane passing through the free end (20) of the tubular protuberance (7) and in the other direction by a plane passing through the large face (21) of the inner ring (11) of the rolling bearing located on the same side as the locking nut (15). The inner rings are axially locked by a locking component, and the sensor is radially inserted in a radially oriented receptacle formed in an external surface of the locking component.
