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.

摘要： A wheel axle bearing unit for a vehicle is to be made lighter in weight, so as to prolong a life span thereof. A first grooved portion is formed by removing an excess in thickness in a region between dual raceways on an outer circumferential surface of a hub and an inner race which constitute the inner member of the wheel axle bearing unit, for enlarging a space inside the bearing, thereby increasing an amount of grease that can be retained in the region between the dual raceways. Also at a position corresponding to the first grooved portion, a second grooved portion is formed by removing an excess in thickness on an inner circumferential surface of an outer race, which constitutes an outer member.

摘要： To provide a rotation detecting device with a function of transmitting a rotational speed detection signal wireless and enable the rotation detecting device to be assembled compact in size without requiring any anti-rusting treatment to a multi-pole magnet assembly and a magnetic ring assembly, the rotation detecting device includes an electric power generator (11) for generating an electric power by a relative rotation between a non-rotatable member (1) and a rotatable member (7). The electric power generator (11) includes a multi-pole magnet assembly (13) and a magnetic ring assembly (12). A wireless transmission device (14) for transmitting the rotational speed detection signal outputted by the electric power generator (11) is employed. A sealing member (18) is also employed for sealing a working space delimited between the non-rotatable member (1) and the rotatable member (7), and the multi-pole magnet assembly (13) and the magnetic ring assembly (12) of the electric power generator (11) confront with each other at a location inwardly of the sealing member (18). The sealing member (18) is mounted on the magnetic ring assembly (12) or the wireless transmission device (14) of an annular configuration.

摘要： To reduce the weight of the wheel support bearing assembly without sacrificing the strength, the wheel support bearing assembly for rotatably supporting a vehicle wheel relative to a vehicle body structure includes a hub axle (2) formed with a radially outwardly extending hub flange (12). This hub flange (12) has an inner peripheral portion and a remaining wall portion other than the inner peripheral portion, and the remaining wall portion thereof is constituted by a plurality of radially outwardly extending ribs (13) each formed with a bolt insertion hole (14). The hub axle (2) also includes a brake pilot area (16) extending outwardly from an outboard face of the hub flange (12) for guiding an inner peripheral surface of the brake rotor (41). At least the root diameter (D1) of at least an inboard face of each rib (13) is chosen to be equal to or smaller than the outer diameter (D2) of the brake pilot area (16).

摘要： To prevent vibrations and uneven wear of a brake resulting from runout of the brake rotor, a reliable wheel bearing assembly with a brake rotor is proposed which needs no troublesome runout adjustment at a car assembling factory. The assembly includes an outer member having two raceways on its inner circumferential surface, an inner member having raceways each provided opposite a respective one of the two raceways, and rolling elements arranged in two rows between the outer and inner members. One of the outer and inner members is provided with a wheel mounting flange, and the brake rotor is mounted to the wheel mounting flange. The runout variation of a side of the brake rotor is maintained within a standard value with a fixed-side member as a datum.
