A device for determining the speed between two members in relative rotation such as the supporting members of the wheel of a vehicle, in particular between the races of a rolling contact bearing substaining the wheel of a vehicle. A first ring or screen (10), integral with the rotating race (11) of the bearing, carries a double magnetized ring (12) with couples of poles opposite in sign between which a magnetic sensor (13) is operatively inserted. The sensor (13) is carried by a second screen or support (14) integral with the fixed race (15) of the bearing. The magnetic sensor (13) is immerged between the n pole pieces, the number of which is corresponding to the couples of poles opposite in sign of the double magnetized ring (12). <IMAGE> |
