| 20090274404 | Wheel Bearing Apparatus Incorporated With A Wheel Speed Detecting Apparatus - A wheel bearing apparatus incorporating a wheel speed detecting apparatus has an outer member and an inner member. Double row rolling elements freely rollably contained between the inner and outer raceway surfaces. Seals are mounted in annular openings formed between the outer member and the inner member. A sensor holder is injection molded from synthetic resin with an embedded wheel speed detecting sensor. The holder is mounted on an inner side end of the outer member. The inner side seal of the seals includes a slinger mounted onto the outer circumference of the inner ring. A pulser ring has an encoder with circumferential characteristics that alternately and equidistantly change. A metal core is press formed from a steel plate and insert-molded into the sensor holder. A sealing member is integrally bonded to the metal core. A connector for electrically connecting the wheel speed detecting sensor to a harness, connected to an electronic circuit, is mounted at a predetermined position on the circumference of the sensor holder. The connector projects radially outward from the circumference at a predetermined inclined. A recess is formed in the connector. The recess is fit onto an inner side end of the outer member in a manner to cover the inner side end, via a predetermined interface. | 11-05-2009 |
| 20090274405 | Wheel Bearing Apparatus for a Vehicle - A vehicle wheel bearing apparatus has a substantially cylindrical outer ring formed with double row outer raceway surfaces on its inner circumference and with press fitting surfaces on its outer circumferences of its cylindrical portions. A pair of inner rings is formed with inner raceway surfaces on their outer circumferences. The inner rings cylindrical portions have fitting surfaces on their inner circumferences. The fitting surfaces fit onto a cylindrical portion of a wheel hub. The inner rings are adapted to be arranged so that end faces of the cylindrical portions abut each other. Double row rolling elements are freely rollably arranged between outer and inner raceway surfaces. At least the outer ring of the outer and inner is formed by pressing or rolling from a plate member or a pipe member. The outer ring and the inner rings have cylindrical portions axially extending, respectively, from the outer raceway surfaces and the inner raceway surfaces. The thickness of the cylindrical portions of the outer ring is thinner than that of the outer raceway surfaces. Seals are arranged in annular spaces formed between the inner circumferences of the cylindrical portions of the outer ring and the outer circumferences of the cylindrical portions of the inner rings. The seals are adapted to be press-fit into the inner circumferences of the cylindrical portions of the outer ring. The double row outer raceway surfaces of the outer ring and the inner raceway surfaces of the inner ring are surface hardened. | 11-05-2009 |
| 20100021099 | Wheel Bearing And A Wheel Bearing Apparatus Having The Wheel Bearing - A vehicle wheel bearing forming a double row angular contact ball bearing of back-to-back duplex bearing type has an outer member formed, on its inner circumference, with outer raceway surfaces with each having a circular arc longitudinal section. A pair of inner rings are each formed, on its outer circumference, with an inner raceway surface having a circular arc longitudinal section arranged opposite to one of the outer raceway surfaces. The end of a smaller diameter side of one inner ring abuts against an end of a smaller diameter side of the other inner ring. Double row balls are contained between the outer and inner raceway surfaces, respectively, of the outer member and inner rings and are held by cages. Seals are mounted in annular openings formed between the outer member and inner rings. The outer member and the inner rings are made by plastically deforming pipe members, The outer and inner raceway surfaces, cylindrical portions of the outer member forming fitting portions of the seals and/or shoulder portions of the inner rings forming land portions are formed with predetermined dimensions and are ground for accuracy. | 01-28-2010 |
| 20100092117 | Wheel Bearing Apparatus Incorporated With A Wheel Speed Detecting Apparatus - A wheel bearing apparatus incorporating a wheel speed detecting apparatus has an outer member, an inner member, double row rolling elements, a sensor holder, and a pulser ring. The sensor holder cover has a cylindrical fitting portion press-fit onto the inner side end portion of the outer member. A flange portion extends radially inward from the fitting portion. The flange portion is in close contact with the end face of the outer member. A bottom portion extends further radially inward from the flange portion. The holding portion is integrally joined to the bottom portion. The flange portion is formed with a flat surface so that it forms an abutting width larger than 5 mm or more, against the end face of the outer member, or larger than 50% or more, relative to the flat width of the end face of the outer member. | 04-15-2010 |
| 20100215304 | Wheel Bearing Apparatus For A Vehicle - A vehicle wheel bearing apparatus has an outer member, an inner member and double row rolling elements freely rollably contained between the outer raceway surfaces and inner raceway surfaces, respectively, of the outer member and the inner member. Either one of the outer member or inner member, on its outer side end, is integrally formed with a wheel mounting flange to mount a wheel. A plurality of bolt apertures is formed in the wheel mounting flange. The wheel is secured on the wheel mounting flange by a plurality of bolts. Cut-out portions are formed between the bolt apertures. The cut-out portions avoid the vicinity of each bolt aperture. Each cut-out portion is formed with a circular arc configuration so that its deepest portion is positioned closely to a pitch circle diameter of the bolt apertures. | 08-26-2010 |
