摘要： To reduce the weight of the wheel support bearing assembly without sacrificing the strength, the wheel support bearing assembly for rotatably supporting a vehicle wheel relative to a vehicle body structure includes a hub axle (2) formed with a radially outwardly extending hub flange (12). This hub flange (12) has an inner peripheral portion and a remaining wall portion other than the inner peripheral portion, and the remaining wall portion thereof is constituted by a plurality of radially outwardly extending ribs (13) each formed with a bolt insertion hole (14). The hub axle (2) also includes a brake pilot area (16) extending outwardly from an outboard face of the hub flange (12) for guiding an inner peripheral surface of the brake rotor (41). At least the root diameter (D1) of at least an inboard face of each rib (13) is chosen to be equal to or smaller than the outer diameter (D2) of the brake pilot area (16).

摘要： An object of the present invention is to provide a bearing apparatus for a driving wheel of vehicle which can prevent generation of stick-slip noise as well as fretting wear and thus can improve durability of the bearing apparatus. According to the present invention, there is provided a bearing apparatus for a driving wheel of vehicle comprising an outer member (10) formed with double row outer raceway surfaces (10a, 10a) on the inner circumferential surface thereof; an inner member (1, 27) formed with double row inner raceway surface (2a (24a), 3a) arranged oppositely to the double row outer raceway surfaces (10a, 10a); double row rolling elements (6) contained freely rollably between the outer and inner raceway surfaces (10a, 10a; 2a (24a), 3a) respectively of the outer and inner member (10; 1, 27); and a constant velocity universal joint (11, 26) for torque transmission inserted into the inner member (10; 1, 27) with abutting thereto and axially separably connected thereto via a nut (19) characterized in that the end surface (13a, 23a, 28a) of a shoulder (13, 28) of an outer joint member (15, 29) and the end surface of the inner member (1, 27) are previously formed so that these end surfaces line contact with each other at a vertex formed by inclined surfaces on the end of the inner member (1,27).
