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 compact bearing device for a drive wheel is provided, which removes backlash within the joint between a wheel hub and a constant velocity universal joint, and increases the rigidity of the bearing device. There is provided a drive wheel bearing device in which a wheel hub and a double-row bearing are integrated into a single unit, and an outer joint member of a constant velocity universal joint is engaged inside the unit via a serrated section. In this structure, at least one of the inner races of the double-row bearing is formed on a separate inner ring engaged onto the wheel hub, irregularities are formed on the outer peripheral surface of the wheel hub, and radial expansion swaging of the wheel hub is used to cause the irregularities to bite into the inner peripheral surface of the inner ring, thereby fastening the wheel hub and the inner ring together through a plastic deformation section.

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.

摘要： An object of the present invention is to enhance assemblability of a wheel bearing device, and stably maintain predetermined torque transmissibility over a long period of time. A shaft portion (12) of a joint outer ring (5) where projections (35) extending in an axial direction are provided is press-fitted into a hole portion (22) of a hub wheel (1) to thereby form recesses (36) by the projections 35 in an inner diameter surface (37) of a shaft fitting hole 22a of the hub wheel (1), by which a recess-projection fitting structure M is constructed, where an entire area of fitting sites of the projections (35) and the recesses (36) are brought into close contact. Moreover, a bolt member (50) is fastened in a bolt hole (13) provided in the shaft portion (12) of the joint outer ring (5) after the construction of the recess-projection fitting structure (M), which restricts separation between the hub wheel (1) and the joint outer ring (5). As the bolt member (50), if an outer diameter of a seating surface thereof (50a1) is d1 and a shaft diameter is d2, a bolt member satisfying a relational expression of 2.3 ‰¤ (d1 /d2) 2 ‰¤ 4.9 is used.
