<P>PROBLEM TO BE SOLVED: To provide a wheel supporting hub unit which withstands the moment load generated by the cornering moment applied to a wheel, enhances the counter-moment rigidity of the hub unit, and minimizes the space increase and weight increase in the axial direction and the radial direction of the hub unit. <P>SOLUTION: The wheel supporting hub unit comprises first, second and third inner raceways 6, 7 and 8 formed on an inner surface of a hub 1, first, second and third outer raceways 16, 17 and 18 formed on an outer surface of an outer ring 20, and first, second and third rolling elements 26, 27 and 28 provided therebetween in a rolling manner. First, second and third bearing parts B1, B2 and B3 are constituted of the first, second and third inner raceways, outer raceways and rolling elements. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
