摘要： A vehicle wheel bearing apparatus has an outer member with a body flange and double row outer raceway surfaces. An inner member includes a wheel hub and an inner ring. They include inner raceway surfaces arranged opposite to the double row outer raceway surfaces. Double row rolling elements are freely rollably contained between the outer and inner raceway surfaces. Outer side rolling elements of the double row rolling elements are balls and inner side rolling elements of the double row rolling elements are tapered rollers. A pitch circle diameter of the inner side tapered rollers is set smaller than that of the outer side balls. A substantially conical recess is formed at an outer side end portion of the wheel hub. The depth of the recess extends to at least near the bottom of the inner raceway surface of the wheel hub. The thickness of a portion of the wheel hub where the inner raceway surface is formed is set within a predetermined range. The outer side wall of the wheel hub has a constant thickness substantially along the inner surface of the recess.

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.

摘要： 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.

摘要： To provide a wheel support bearing assembly, in which the sufficient proof strength of an inner race during assemblage onto the vehicle body can be secured without its function being lowered, the wheel support bearing assembly includes an outer member, an inner member, and rows of rolling elements interposed therebetween. The inner member includes an hub axle having a flange and an inner race on an inner race mount, with raceways defined in the hub axle and the inner race. The inner race has a counterbore at its inboard end. The hub axle has a plastically deformed portion which engages an axially oriented surface of the counterbore when radially outwardly crimped and does not protrude outwardly beyond an inboard end face of the inner race. The difference P between the inner race mount and an outer peripheral face of the plastically deformed portion is 0.13 mm or more.
