An asymmetrical wheel hub assembly

An asymmetrical wheel hub assembly (10) with an axis (A) of rotation and provided with two rows (C1, C2) of rolling bodies (13) with different pitch diameters and, for each row of rolling bodies (13), with an inner raceway (111, 112) and an outer raceway (121, 122) which are arranged in axially staggered positions in accordance with a respective angle of contact and along a respective load line (111, 112) in order to allow the assembly to support combined loads, the raceways of each row of rolling bodies (13) being provided with respective osculations which are defined by the ratio between the radiuses of curvature of the raceways and the outer diameters of the rolling bodies (13) of the associated row of rolling bodies (13). The angle of contact and the osculations of a first row (C1) of rolling bodies (13) of the two rows (C1, C2) of rolling bodies (13) are different from the angle of contact and, respectively, from the osculations of a second row (C2) of rolling bodies (13) of the two rows (C1, C2) of rolling bodies (13).
