More Information
Summary:Angular velocity sensor device for a rotating member mounted using a roller bearing on a non-rotating member, the said device comprising a coder element (11) integral with the rotating ring (6) of the bearing and producing an alternating magnetic field, a sensor element (12) integral with the non-rotating ring (7) of the bearing and disposed opposite the coder element with an air gap, the coder element (11) comprising two concentric multiple-pole rings (14, 15) with axial magnetisation, and the sensor element (12) comprising an induction coil (17) coaxial with the multiple-pole rings and interacting with a magnetic flux concentrator (18) whose collector branches (20, 21) are directed axially facing the multiple-pole rings (14, 15) of the coder element. Application to wheel hubs for motor vehicles fitted with an ABS system.
