BEARING FOR AUTOMOBILE WHEEL, AND LOAD MEASUREMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a bearing for automobile wheels and a load measurement method that facilitats measurement of loads and the moments. SOLUTION: The bearing 1 for automobile wheels comprises: an inner race 2, having a flange section 26 for engaging a hub bolt 261; and an outer race 3 extrapolated to the inner race 2 via two rows of bearing balls 40, arranged in the direction of the axis center of the inner race 2. The outer race 3 comprises: an inner-periphery section 31 that is in contact with each row of bearing balls 40; and an outer-periphery section 32, that is arranged at the outer-periphery side of the inner-periphery section 31 and elastically holds the inner-periphery section 31. A sensor (load sensor 5), for distortion measurement for measuring the distortions generated between the inner-periphery section 31 and the outer-periphery section 32, is arranged at least at one location between the outer-periphery section 32 and the inner-periphery section 31.
