20090154856 | Wheel Support Bearing Assembly and Method of Manufacturing the Same - To provide a wheel support bearing assembly, which is effective to avoid an inner race detachment during assemblage onto an automotive vehicle. The assembly is provided with an inner member made up of a hub axle and an inner race mounted on an outer periphery of an inboard end portion of the hub axle. The inner race has an inner periphery provided with an stepped area that extends to an inboard annular face of the inner race and has a depth measured at an inner peripheral edge of an inboard annular face, and an inner surface of this stepped area is of a shape made up of a straight area and an inclined surface continued from an outboard end of the straight area to the inner peripheral surface, and a plastically deformed portion engageable with the inclined surface as a result of crimping is provided in the hub axle. | 06-18-2009 |
20090268998 | WHEEL SUPPORT BEARING ASSEMBLY - A wheel support bearing assembly includes an outer member, an inner member and double row balls. The inner member includes a hub unit, which has a wheel mounting flange defined in an outer periphery thereof, and an inner ring mounted on the outer periphery of the inboard end of the hub unit. A shoulder is provided in an inner peripheral edge of the inboard end face of the inner ring. A crimped portion, engageable with a stepped face of the shoulder, is provided in the inboard end of the hub unit by diameter expansion. The crimped portion is formed by crimping such diameter expanded portion which is thin walled by providing a hub inner diameter setback in the inner periphery of the inboard end of the hub unit. This thin walled portion is positioned on a side inboardly of the straight line defining a ball contact angle in the inboard raceway surface. | 10-29-2009 |
20100046871 | SENSOR-EQUIPPED BEARING FOR WHEEL - To provide a sensor equipped wheel support bearing assembly, in which a load sensor can be installed compactly in an automotive vehicle, maintaining a high sensitivity while damage and/or malfunction caused by the external environments and/or the electromagnetic noises are avoided, with low manufacturing cost. This bearing assembly includes outer and inner members having respective rolling surfaces and a plurality of rows of rolling elements interposed between those rolling surfaces. A strain sensor unit including a sensor element is fitted to one of the outer and inner members, which is a stationary member, for example, the outer member. A sensor mounting surface of the strain sensor unit fitted with the sensor element has a covering member made of a resin, which is over-molded, or an elastomer bonded by vulcanization, so as to cover the sensor element sealingly. | 02-25-2010 |
20100232734 | SEALING DEVICE FOR BEARING ASSEMBLY AND WHEEL SUPPORT BEARING ASSEMBLY THEREWITH - A bearing sealing device is provided between inner and outer members of a wheel support bearing assembly and includes an annular sealing plate of an L shaped section and an elastic sealing member having an elastic body secured to a core metal of a reverse L-shaped section. The sealing plate includes a cylindrical wall, mounted on an outer periphery of the inner member, and a radial wall extending upwardly from one end thereof. The core metal includes a cylindrical wall, mounted on an inner periphery of the outer member, and a radial upright wall extending radially inwardly from one end thereof. The elastic body includes two side sealing lips, arranged radially of the core metal and having their tips held in contact with the radial upright wall. The distance between those side sealing lips is chosen to be equal to or greater than 0.1 mm. | 09-16-2010 |
20100278468 | WHEEL SUPPORT BEARING ASSEMBLY AND METHOD OF MAKING THE SAME - A support bearing assembly includes a plural rows of rolling elements ( | 11-04-2010 |
