Title:
SENSOR-EQUIPPED SEALING DEVICE, AND ROLLING BEARING DEVICE ADAPTED FOR USE IN VEHICLE AND USING THE SEALING DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/059788
Kind Code:
A1
Abstract:
Provided are a sensor-equipped sealing device for a rolling bearing device,
in which sufficient magnetic force is available for the sensor, and a rolling
bearing device for a vehicle, using the sensor-equipped sealing device. A rolling
bearing device (1) for a vehicle has a sensor-equipped sealing device having
an annular slinger (10) fixed to an inner shaft (2), a magnetic encoder (11) co-rotatably
fixed to the slinger (10), a core (14) fixed to an outer ring (3) and having a seal
member (15) in sliding contact with the slinger (10), and a sensor section (12)
having a magnetic sensor (13) for detecting relative rotation between the outer
ring (3) and the inner ring (2) based on a change of magnetic poles by the magnetic
encoder (11). The magnetic encoder (11) is constructed from a plastic magnet
containing magnetic powder having magnetism oriented to a predetermined direction.
