ROLLING BEARING DEVICE WITH SENSOR

摘要

[Resolving Means] A rolling bearing device with a sensor includes: a tubular fixed bearing ring which is fixed to a vehicle body side; a rotating bearing ring which is rotatably inserted in an interior of the fixed bearing ring and is fixed to a tire side; rolling elements which are rollably disposed between these bearing rings; and a sensor device disposed on a fixed bearing ring side. The sensor device has at least two sensors which are arranged at positions perpendicular to each other in a circumferential direction of the fixed bearing ring, and which are respectively capable of detecting the ground contact load of the tire, the sensor device being so constructed as to be able to detect a ground contact load of the tire based on cycles of outputs obtained from the at least two sensors.
