Abstract: A vehicle wheel bearing apparatus has an outer member and a constant velocity joint connected to a wheel hub. The wheel hub and the constant velocity joint outer joint member are axially detachably connected. An end face of the caulked portion has a flat surface. A cap is mounted on the caulked portion. The cap has a metal core press-formed of a corrosion resistant steel sheet with a generally ring shape having a substantially L-shaped cross-section and a molded portion. The molded portion is formed from synthetic resin and has an infinite number of micro indentations on its surface. The cap abuts against the end face of the caulked portion and the shoulder portion of the outer joint member.

Abstract: A bearing device (1) for a vehicle wheel provided with: an outer member (2); and an inner member comprising a hub wheel (3), and at least one inner wheel (4) press-fitted into the small-diameter ridge (3A) of the hub wheel (3); wherein a belt-shaped part (2F) that radially protrudes by a protrusion amount (P1) is formed over a prescribed width (W1) in the outer peripheral surface of the outer member (2) so that at least part of the belt-shaped part (2F) radially overlaps the outside rolling surface (2D) which is on the vehicle-wheel-attachment-flange-facing side of the outer member (2). The present invention addresses the problem of providing a bearing device for a vehicle wheel in which the amount of deformation in an opening of an outer member can be reduced and decreases in rolling fatigue service life can be prevented while keeping overall weight increase to a minimum.

Abstract: A wheel bearing apparatus has an outer member with a body mounting flange and double row outer raceway surfaces, an inner member with double row inner raceway surfaces opposing the double row outer raceway surfaces, and double row rolling elements contained between the inner raceway surfaces and the outer raceway surfaces, respectively, of the inner member and the outer member. A plurality of bolt insertion holes formed in the outer member body mounting flange. An abutment surface, to abut against the body-side member, is formed around each bolt insertion hole as a surface projecting from the inner-side surface of the body mounting flange with a step height. A relative difference between the step heights of the abutment surfaces is limited to a minimum.

Abstract: The present invention addresses the problem of providing a bearing device for wheels, the bearing device for wheels being configured so as to reduce an amount of deformation of an opening of an outer member while minimizing an increase of an overall the weight, thus preventing a deterioration in rolling fatigue life. A bearing device for wheels is provided with: an outer member having double-row outer rolling surfaces; a hub ring having a wheel mounting flange and having a small-diameter stepped section; and an inner member constituted by at least one inner ring press-fitted over the small-diameter stepped section, the inner member having double-row inner rolling surfaces facing the double-row outer rolling surfaces. A band-shaped section having a predetermined band width and protruding radially by a protrusion amount is formed on at least a part of the wheel mounting flange-side outer peripheral portion of the opening of the outer member.

Abstract: A wheel bearing apparatus has an outer member, an inner member and double row rolling elements freely rollably contained between double row inner raceway surfaces and outer raceway surfaces of the inner member and the outer member. A plurality of bolt insertion bores, that fastening bolts pass through to fasten to the knuckle, are formed on the body mounting flange at plurality of positions circumferentially along the body mounting flange. The outer member is previously formed by hot forging. A seating surface for the fastening bolts is formed on an outboard-side surface of the body mounting flange by cold forging.
