Abstract: A rolling bearing unit for the hub of a vehicle wheel has an outer rotating race (10), a radially inner stationary race (11), a sealing device (16) between the races (10, 11), and a device for measuring the rotating speed of the outer race (10). The measuring device has an encoder wheel (13) in the form of a radially oriented annular disc of magnetised plastic or rubber material. The rolling bearing has a metallic annular insert (14) adapted for fixing the encoder wheel (13) to the outer race (10); the insert (14) forms: an outer cylindrical portion (14a) for forcefully fitting to an outer surface (10a) of the outer race (10); a radial wall portion (14b, 14d) that concurs in forming an annular seat for accommodating the encoder wheel, and that extends radially inwardly so as to co-operate with the sealing device (16) to close the gap between the races (10, 11); and a joining portion (14c) between the outer cylindrical portion (14a) and the radial wall portion (14b, 14d), on which an axial thrust is applied for performing the force fitting.

Abstract: A tire (12) used includes a steel belt in its outer circumferential portion. A magnetic sensor (14) including a pair of magnetic detection elements (18A, 18B), which are arranged so that their magnetic detection directions become parallel to each other or series each other, is set in the vicinity of a rear tire (12) in a trunk room of a vehicle (10). Changes in magnetic field upon revolution of the tire (12) are differentially detected by the magnetic detection elements (18A, 18B), and the revolution of the tire (12) is detected on the basis of the differentially detected output waveform. Among a plurality of peaks present in the differentially detected output waveform, a peak, the potential difference from the immediately preceding peak of which is equal to or larger than a predetermined threshold value, is detected as an effective peak, which is effective for tire revolution detection, and the revolution speed of the tire is calculated by detecting the number of effective peaks.
