<p><P>PROBLEM TO BE SOLVED: To provide a rolling bearing device with a sensor for directly cooling the sensor by a blower fan disposed on a rotation member side, and preventing failure due to heat. <P>SOLUTION: The rolling bearing device with the sensor includes an inner ring 2b relatively rotating with an outer ring 2a connected to a vehicle fixing member 6 on a vehicle inner side, an annular magnetic encoder part 10 fixed to the vehicle inner side of the inner ring 2b and having a magnetic characteristic varying alternately in a peripheral direction, and an ABS sensor 11 fixed to the vehicle fixing member 6 and arranged to be opposite to the magnetic encoder part 10 so as to detect magnetic change by rotation of the magnetic encoder part 10. An air stream is generated in an axial direction of a rotating axis by the blower fan 12g placed adjacently to the vehicle inner side of the ABS sensor 11 and rotated by rotation of the inner ring 2b, and the air stream is brought into contact with the ABS sensor 11 whose temperature is raised by heat generation of a disk rotor 3b during braking. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
