SENSOR-EQUIPPED WHEEL BEARING
Document Type and Number:
WIPO Patent Application WO/2012/153721
Kind Code:
A1
Abstract:
A sensor-equipped wheel bearing provided with a weight sensor, wherein the wheel bearing has a rolling element (5) disposed between mutually opposing double rows of roller surfaces (3, 4) of an outer member (1) and an inner member (2). A plurality of sensor units (20) composed of a strain-generating member (21) and two or more sensors (22) mounted thereon to detect strain is provided. The strain-generating member (21) is a single strip-shaped member continuous across the plurality of sensor units (20), and is disposed in a position in which two or more contact fixed parts (21a) assigned to each of the sensor units (20) are set at a distance from each other in the circumferential direction and in the same axial direction position on the outside diameter surface of a fixed-side member of the outer member (1) and the inner member (2). The weight acting on the wheel bearing is estimated by an estimation means (32) from the output signals of the two or more sensors (22) of the sensor unit (20).
