摘要： A reliable brake rotor and wheel bearing assembly are proposed which make unnecessary adjustment of runout of brake rotor at the customer's factory. For runout of each of the mounting surface and back of the brake rotor itself, and runout of the side of the wheel mounting flange of the inner member to which is mounted the brake rotor, the maximum difference between the peaks of crests and troughs in each period of surface runout is restricted within a standard value, and the brake rotor is mounted to the wheel mounting flange, thereby eliminating the necessity of mounting of the brake rotor and adjustment of runout after mounting at the customer's factory to provide a reliable automotive wheel bearing assembly.

摘要： A wheel bearing assembly is provided which can suppress brake judder. A film is disposed between the brake rotor-mounting surface of the wheel mounting flange and an abutment surface of a brake rotor to fill a gap therebetween to suppress the deformation of the brake rotor. Also, by concentrating the contact force between the wheel-mounting flange and the brake rotor when a disc wheel of the wheel is tightened to the hub bolts to a portion near the hub bolts, the contact between the wheel-mounting flange and the brake rotor on the surfaces between the hub bolts is suppressed so that undulation of the flat surfaces between the hub bolts will not cause deformation of the brake rotor.

During the manufacturing, a swaged portion is formed in a manner as a non-hardened region, and in a manner that variations based on a reference surface in the axial direction of the flat surface are restricted within +/−0.2 mm. The reference surface is provided with an end face on an outboard side of a flange for an attachment of a wheel or an end face on an inboard side of the flange for attachment to a vehicle body. Part of the swaged portion making contact with an outer joint member of to drive wheel bearing device is formed into a flat surface. Serrations and a pilot part are formed on an inner periphery of a first inner member of the drive wheel bearing device. An inner peripheral surface of the pilot part is formed as a turned surface, and the turned surface has been turned after forming the swaged portion. A serrated shaft is formed on the outer joint member for transmitting torque to and from the first inner member through the serrations and an outer periphery surface opposing to the pilot part. A surface hardened layer is formed on the outer joint member by heat treatment in a region that includes at least the serrated shaft.

摘要： A wheel bearing device having a unitized hub ring, double-row bearing and constant velocity universal joint with one of double-row inner raceways formed on the joint outer ring. An end portion of the joint outer ring is fitted to an outside periphery of the hub ring through serrated portions. The hub ring is plastically deformed and expanded from an inside diameter side toward an outside diameter side by pushing a steel ball into a through hole of the hub ring preventing play in the serrated portions by the diameter expansion. A surface-hardened layer is formed at least on a base portion of the wheel mounting flange.
