    摘要： A wheel bearing apparatus has an outer member formed with double row outer raceway surfaces on its inner circumferential surface. An inner member includes a wheel hub with a wheel mounting flange integrally formed at one end and a cylindrical portion axially extending from the wheel mounting flange. At least one inner ring is fit onto the cylindrical portion of the wheel hub. The inner ring is formed with double row inner raceway surfaces on its outer circumferential surface. The double row inner raceway surfaces are arranged opposite to the double row outer raceway surfaces. Double row rolling elements are rollably arranged between the outer and inner raceway surfaces, via cages. A seal is mounted on one end of the outer member. The seal has integrally formed side lips adapted to be in sliding contact with the wheel hub. The base of the wheel mounting flange is formed to have a curved surface, in cross-section, of a circular arc. The seal has three inclined side lips each extending radially outward from the seal body. The lips are adapted to be in sliding contact with the base of the wheel mounting flange. Interference of the side lips against the base of the wheel mounting flange is set so that the radially inner side lip has a smaller interference than that of the radially outer side lips, in order.

    摘要： A wheel bearing apparatus is formed as a unit of a wheel hub and a double row taper roller bearing. An outer member is formed with double row tapered outer raceway surfaces, each opened axially outward, on its inner circumference. An inner member, including the wheel hub, has a wheel mounting flange integrally formed at one end of the wheel hub. A cylindrical portion axially extends from the wheel mounting flange. At least one inner ring is fit onto the cylindrical portion of the wheel hub via a predetermined interference. Each inner ring is formed with one of the tapered double row inner raceway surfaces on its outer circumference. The inner raceway surfaces are arranged opposite to one of the double row outer raceway surfaces. On its larger outer diameter side, the inner ring has a larger flange portion to guide the tapered rollers. Double row tapered rollers are rollably arranged between the outer and inner raceway surfaces, via cages. The at least one inner ring is secured on the wheel hub by a caulked portion. The caulked portion is formed by plastically deforming the end of the cylindrical portion radially outward. A predetermined hardened layer is formed by high frequency induction hardening over a range from the base of the wheel mounting flange to the cylindrical portion. A position of the inner side end of the hardened layer is set within a range from an edge of a chamfered portion at the caulked side of the inner ring to a position corresponding to a root of the larger flange portion.

    摘要： A vehicle wheel bearing apparatus has an outer member with double row outer raceway surfaces on its inner circumferential surface. An inner member includes a wheel hub and at least one inner ring. An outer joint member forms a constant velocity universal joint. The outer joint member has a cup-shaped mouth portion. A shoulder portion forms the bottom of the mouth portion. A shaft portion axially extends from the shoulder portion. The shaft is axially separably and torque transmittably inserted into the wheel hub with the shoulder abutted against the caulked portion to transmit torque. The inner ring is axially secured relative to the wheel hub by a caulked portion. The caulked portion is formed by plastically deforming, radially outwardly, the end portion of the cylindrical portion. The caulked portion has a flat surface formed by a cutting process that is adapted to surface contact the shoulder. The radially outermost end of the flat surface is arranged so that it does not abut against the shoulder.
