    摘要： A bearing device for a wheel is capable of suppressing a backlash in a circumferential direction, is excellent in coupling operability of a hub wheel and an outer joint member of a constant velocity universal joint, and is excellent for maintenance by allowing separation of the hub wheel and the outer joint member of the constant velocity universal joint. In the bearing device for a wheel, a hub wheel, a double-row roller bearing, and a constant velocity universal joint are unitized together, and the hub wheel and a shaft section of an outer joint member of the constant velocity universal joint are separably coupled with each other through intermediation of a recess-projection fitting structure, the shaft section being inserted in a fitting manner into a hole portion of the hub wheel.

    摘要： A hub wheel (21) and an outer joint member (3) are coupled to each other through intermediation of a recess-projection fitting structure (M). The recess-projection fitting structure (M) can be separated by being applied with a pulling-out force in an axial direction under a state in which a bolt member (30) is removed, and can be re-formed by re-screwing the bolt member (30) into a bolt hole (5d). The hub wheel (21) comprises a receiving portion (23a) for receiving the bolt member (30). The shaft portion (5) has a small diameter portion (5a) serving as a fit-in portion to be fitted along an inner periphery of the receiving portion (23a) under a state in which the recess-projection fitting structure (M) is formed. The small diameter portion (5a) is used as a part for confirming the accuracy and the state of the recess-projection fitting structure (M).

    摘要： A vehicle wheel bearing apparatus with a back-to-back double row tapered roller bearing has an outer member integrally with a body mounting flange and double row outer raceway surfaces tapered open respectively axially inward and outward. An inner member include a wheel hub and an inner ring or an outer joint member of a constant velocity universal joint. The wheel hub has a wheel mounting flange and one inner raceway surface arranged oppositely to one of the double row outer raceway surfaces and a cylindrical portion. The inner ring or the outer joint member of a constant velocity universal joint are press fit onto the cylindrical portion and include the other inner raceway surface arranged opposite to the other raceway surface of the double row outer raceway surfaces. Double row tapered rollers are freely rollably held between the outer and inner raceway surfaces by cages. Seals are arranged in annular openings formed by the outer and inner members. The cages are formed of synthetic resin. Posts between pockets of the cages are arranged to be positioned radially inward of the pitch circle diameter of the tapered rollers. The width of an opening radially inward of each pocket is set so that each tapered roller is held within the pocket. The contacting tapered surfaces of the posts open radially outward so that the rollers do not fall out radially inward.

    摘要： A bearing apparatus for a driving wheel of vehicle for rotatably supporting the driving wheel relative to a body of a vehicle has a wheel hub, integrally formed with a wheel mounting flange, a constant velocity universal joint and a double row rolling bearing assembled as a unit. A separate inner ring is press fitted onto a cylindrical portion of the wheel hub. An outer joint member of the constant velocity universal joint is fitted within the wheel hub. The bore surface of the wheel hub is formed with a hardened irregular portion. The wheel hub and the outer joint member are integrally connected with making the hardened irregular portion of the wheel hub bite into the outer circumferential surface at a fitting portion of the outer joint member by radially outwardly expanding the fitting portion of the outer joint member. The hardness of the bore surface of the fitting portion of the outer joint member is higher than that of the core portion of the fitting portion of the outer joint member.

    摘要： Provided is a bearing device for a wheel that can realize prevention of a backlash in a circumferential direction and is excellent in workability of connection of a hub wheel and an outer joint member of a constant velocity universal joint. Further, provided is a bearing device for a wheel that can prevent deterioration in NVH characteristics, which is caused by the backlash occurring in a joint section between the hub wheel and the constant velocity universal joint or between an outer member and a knuckle, and can perform rotation torque transmission with high accuracy. The bearing device includes a recess-projection fitting structure (M) in which the hub wheel (1) and a shaft section (12), which is fitted in a hole (22) of the hub wheel (1) of the outer joint member of the constant velocity universal joint (3) are unitized together. In the recess-projection fitting structure (M), entire fitting regions among projections (35) on the outer surface of the shaft section (12) of the outer joint member and recesses (36), which fit on the projections, are brought into intimate contact with each other.
