摘要： A vehicle wheel bearing apparatus has an outer member with a body flange and double row outer raceway surfaces. An inner member includes a wheel hub and an inner ring. They include inner raceway surfaces arranged opposite to the double row outer raceway surfaces. Double row rolling elements are freely rollably contained between the outer and inner raceway surfaces. Outer side rolling elements of the double row rolling elements are balls and inner side rolling elements of the double row rolling elements are tapered rollers. A pitch circle diameter of the inner side tapered rollers is set smaller than that of the outer side balls. A substantially conical recess is formed at an outer side end portion of the wheel hub. The depth of the recess extends to at least near the bottom of the inner raceway surface of the wheel hub. The thickness of a portion of the wheel hub where the inner raceway surface is formed is set within a predetermined range. The outer side wall of the wheel hub has a constant thickness substantially along the inner surface of the recess.

摘要： A vehicle wheel bearing apparatus has an outer member on its inner circumference with double row tapered outer raceway surfaces arranged so that each smaller diameter side faces toward each other. An inner member includes a wheel hub and an inner ring. The wheel hub has an integrally formed wheel mounting flange. Its outer circumference has one inner raceway surface arranged opposite to one of the double row outer raceway surfaces. A cylindrical portion axially extends from the inner raceway surface. The inner ring is fit onto the cylindrical portion of the wheel hub, via a predetermined interference. The inner ring outer circumference has another inner raceway surface arranged opposite to the other of the double row outer raceway surfaces. Double row tapered rollers are freely rollably contained between the inner and outer raceway surfaces, respectively, of the inner member and the outer member. Seals are mounted in annular openings formed between the outer member and the inner member. The inner ring is formed with a large flange on its larger diameter side of the inner raceway surface. The larger flange guides the inner side tapered rollers of the double row tapered rollers. A flange ring is fit onto the wheel hub at a place adjacent to the wheel mounting flange to guide the outer side tapered rollers of the double row tapered rollers. The flange ring abuts against and guides the larger end faces of the outer side tapered rollers. A pitch circle diameter of a row of outer side tapered rollers is set larger than a pitch circle diameter of a row of inner side tapered rollers.

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. The wheel hub has a wheel mounting flange formed at one end. A cylindrical portion axially extends from the wheel mounting flange. The inner ring has at least one inner raceway surface arranged opposite to the plurality of outer raceway surfaces. The inner ring is press fit onto the cylindrical portion of the wheel hub. Double row rolling elements are freely rollably contained between the outer and inner raceway surfaces. 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.
