20090046972 | Bearing Apparatus For A Wheel Of Vehicle - A vehicle wheel bearing apparatus with a back-to-back double row tapered roller bearing has an outer member integrally with a body mounting flange and double row outer raceway surfaces tapered open respectively axially inward and outward. An inner member include a wheel hub and an inner ring or an outer joint member of a constant velocity universal joint. The wheel hub has a wheel mounting flange and one inner raceway surface arranged oppositely to one of the double row outer raceway surfaces and a cylindrical portion. The inner ring or the outer joint member of a constant velocity universal joint are press fit onto the cylindrical portion and include the other inner raceway surface arranged opposite to the other raceway surface of the double row outer raceway surfaces. Double row tapered rollers are freely rollably held between the outer and inner raceway surfaces by cages. Seals are arranged in annular openings formed by the outer and inner members. The cages are formed of synthetic resin. Posts between pockets of the cages are arranged to be positioned radially inward of the pitch circle diameter of the tapered rollers. The width of an opening radially inward of each pocket is set so that each tapered roller is held within the pocket. The contacting tapered surfaces of the posts open radially outward so that the rollers do not fall out radially inward. | 02-19-2009 |
20090046975 | Bearing Apparatus for a Wheel of Vehicle and an Axle Module Having the Bearing Apparatus - An axle module with a bearing apparatus has an outer joint member | 02-19-2009 |
20090069100 | Joint Assembly, A Wheel Bearing Apparatus, And The Assemblies Included In An Axle Module - A joint assembly has a pair of constant velocity universal joints and a connecting drive shaft. A cover unit protects the constant velocity universal joints and prevents hanging down of the joints under their own weight. The unit cover is arranged to cover the outer circumferential surfaces of the pair of constant velocity universal joints and boots. The unit cover is formed from elastomer material by injection molding. The cover unit inner circumferential surface has a configuration corresponding to the outline configurations of the pair of constant velocity universal joints and the boots. | 03-12-2009 |
20090136168 | Wheel Bearing Apparatus For A Driving Wheel - A wheel bearing apparatus for a driving wheel is formed as a unit of a wheel hub, a double row rolling bearing and a constant velocity universal joint. The double row rolling bearing has an outer member with a body mounting flange mounted on a knuckle and double row outer raceway surfaces. An inner member includes the wheel hub and an outer joint member of the constant velocity universal joint. The wheel hub has an inner raceway surface corresponding to one of the double row outer raceway surfaces. The outer joint member has another inner raceway surface corresponding to the other of the double row outer raceway surfaces. Double row rolling elements are rollably arranged between the outer and inner raceway surfaces. Seals are mounted in an annular space opening formed between the outer member and the inner member. A sensor is fit into a mounting aperture formed in the knuckle. A pulser ring is mounted on the outer circumferential surface of the outer joint member. It opposes the sensor via a predetermined radial gap. The outer diameter of the pulser ring is smaller than the inner diameter of the knuckle. | 05-28-2009 |

20130172088 | WHEEL BEARING DEVICE - An object of the present invention is to enhance assemblability of a wheel bearing device, and stably maintain predetermined torque transmissibility over a long period of time. A shaft portion ( | 07-04-2013 |
20140339885 | Wheel Bearing Apparatus - A wheel bearing apparatus has an outer member, an inner member including a wheel hub and at least one inner ring, and double row rolling elements freely rollably contained between the inner and outer raceway surfaces of the inner and outer members via cages. A hardened ring-shaped gear member is mounted on an end of a cylindrical portion of the wheel hub. The gear member is formed with a gear portion on its outer circumference and with a splined portion on its inner circumference. The splined portion engages a hub-splined portion formed on the outer circumference of the cylindrical portion of the wheel hub. A contacting surface of the gear member and a contacting surface of the inner ring that abut against each other are ground. The inner rings are axially immovably secured under a condition where a predetermined amount of a bearing pre-stress is applied to the inner rings via the gear member. | 11-20-2014 |
