    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.

Thus, the recess-projection fitting structure (M) is realized, in which the projecting portions (35) and the recessed portions (36) are held in close contact with each other through intermediation of an entire region of fitting contact regions (38) therebetween. The recess-projection fitting structure (M) allows separation by being applied with a pulling-out force in the axial direction.

    摘要： A shaft portion of a joint outer ring where projections extending in an axial direction are provided is press-fitted into a hole portion of a hub wheel to thereby form recesses by the projections in an inner diameter surface of a shaft fitting hole of the hub wheel, by which a recess-projection fitting structure is constructed. An entire area of fitting sites of the projections and the recesses are brought into close contact. Moreover, a bolt member is fastened in a bolt hole provided in the shaft portion of the joint outer ring after the construction of the recess-projection fitting structure, which restricts separation between the hub wheel and the joint outer ring. As the bolt member, if an outer diameter of a seating surface thereof 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.

    摘要： Provided is a bearing device for a wheel capable of suppressing a backlash in a circumferential direction, excellent in coupling workability of a hub wheel and an outer joint member of a constant velocity universal joint, and excellent in strength owing to stable fitting between the hub wheel and the outer joint member of the constant velocity universal joint. An axle module using such bearing device for a wheel is also provided. Projecting portions extending in an axial direction are provided on one of an outer surface of a shaft section of the outer joint member and an inner surface of a hole portion of the hub wheel. The projecting portions are press-fitted into the other along the axial direction, and recessed portions are formed in the other through press-fitting of the projecting portions. Thus, a recess-projection fitting structure is formed, in which the projecting portions and the recessed portions are held in close contact with each other through an entire region of fitting contact regions therebetween. Hardness of at least press-fitting start end portions of the projecting portions is set to be higher than hardness of a recessed-portion forming region. A hardness difference therebetween is set to be equal to or larger than 20 points in HRC.
