SENSOR BEARING UNIT AND ROLLING BEARING ASSEMBLY COMPRISING SUCH A UNIT

摘要

This sensor bearing unit, comprises a bearing (2) including a rotating ring (22) and a stationary ring (24), a pre-stressing element (4) for pre-stressing the stationary ring, adapted to exert a pre-stressing force between a housing (H) in which the bearing is mounted and the stationary ring and a sensor unit including an impulse ring (62) coupled in rotation to the rotating ring (22) and a sensing unit (64) comprising at least one sensing element (641) mounted in a sensor body (66) which is fixed to the stationary ring. The sensor body comprises an axial surface (661) against which the pre-stressing element exerts the pre-stressing force, which is thereby transmitted via the sensor body to the stationary ring.
