摘要： A wheel bearing apparatus has an outer member, an inner member and double row rolling elements contained between outer raceway surfaces and inner raceway surfaces, respectively, of the outer member and the inner member. A vibration damping mechanism is mounted on a portion of the outer member or the inner member except at portions engaging with mating components.

摘要： A sensor-equipped wheel support bearing assembly is provided which performs high-accuracy load estimation without providing with another sensor, even in a state where a ground contact load on a wheel supported by the bearing is very low as compared to other wheels. The assembly includes: a plurality of sensor units (20) detecting a load on a wheel support bearing segment (100); sensor signal calculator (31) processing sensor signals (S) from the units; and load calculation processor (32) calculating a load on a road surface contact point on a wheel, based on the processed information. The processor (32) determines whether a target wheel is in a predetermined low load state, based on information of a detected load on a wheel other than the target wheel; and switches a load calculation scheme in accordance with a result of the determination to calculate a load on the wheel.
