WHEEL BEARING DEVICE WITH SENSORS

摘要

PROBLEM TO BE SOLVED: To provide a wheel bearing device with sensors, which can estimate an accurate load value without being affected by frequencies of vibrations generated in input loads.SOLUTION: A wheel bearing 100 includes: a plurality of sensors 20 detecting a load applied to the bearing; signal processing means 31 generating signal vectors from output signals of the sensors 20; load arithmetic processing means 32 calculating the load applied to a wheel from the signal vectors; and input load vibration detection means 33 detecting a variation component of an input load contained in the output signal of each of the sensors 20. The load arithmetic processing means 32 switches methods of load arithmetic processing according to the variation components detected by the input load vibration detection means 33, and calculates the load.
