摘要： Provided is a small-sized, lightweight, low-cost, and highly reliable bearing device for a driving wheel which needs no tapered spline, and eliminates a circumferential backlash in spline fitting portions to thereby prevent unusual noise. The bearing device for a driving wheel comprises an outer race (5) having an inner periphery in which double-row outer raceway surfaces (13, 14) are formed; a hub wheel (1) and an inner race (2) having outer peripheries in which double-row inner raceway surfaces (7, 8) opposed to the outer raceway surfaces (13, 14) are formed; and double-row rolling elements (3, 4) interposed between the outer raceway surfaces (13, 14) of the outer race (5) and the inner raceway surfaces (7, 8) of the hub wheel (1) and the inner race (2). A shaft hole (28) of the hub wheel (1) is formed into a cylindrical shape, and a male spline (26) is formed on an outer periphery of a stem section (27) of the outer joint member (15) so that the stem section (27) of the outer joint member (15) is press-fit into the shaft hole (28) of the hub wheel (1). With this, recesses caused to closely fit on the male spline (26) with interference are formed in the shaft hole (28) of the hub wheel (1), whereby the hub wheel (1) and the outer joint member (15) are separably coupled to each other.

摘要： One object of the present invention is to provide a wheel bearing apparatus which can solve problems of prior art and thus achieve improved detection accuracy and sealability by increasing the rigidity of the second cap. According to the present invention, there is provided a wheel bearing apparatus comprising an outer member; an inner member including a hub wheel and at least one inner ring; double row rolling elements contained between the inner raceway surfaces and outer raceway surfaces of the inner member and outer member; a pulser ring adapted to be fitted onto the outer circumference of the inner ring and having characteristics alternately and equidistantly varying along its circumferential direction; a cup-shaped second cap press-formed of steel sheet and fitted on the inboard-side end of the outer member; and a rotational speed sensor mounted on the second cap at a radially outer position thereof, the rotational speed sensor being arranged oppositely to the pulser ring via a predetermined axial air gap characterized in that a cup-shaped first cap is press-fitted into the inner circumference of an inboard-side end of the outer member via a predetermined interference, the first cap being press-formed of non-magnetic austenitic stainless steel sheet and comprising a cylindrical fitting portion press-fitted into the inner circumference of the inboard-side end of the outer member, a disc portion extending radially inward from the fitting portion and opposing to the pulser ring via a small axial gap; that said rotational speed sensor is arranged oppositely to the pulser ring via the first cap with being abutted against or closed to the disc portion of the first cap; and that said second cap is press-fitted into the inner circumference of an inboard-side end of the outer member via a predetermined interference.

摘要： A compact bearing device for a drive wheel is provided, which removes backlash within the joint between a wheel hub and a constant velocity universal joint, and increases the rigidity of the bearing device. There is provided a drive wheel bearing device in which a wheel hub and a double-row bearing are integrated into a single unit, and an outer joint member of a constant velocity universal joint is engaged inside the unit via a serrated section. In this structure, at least one of the inner races of the double-row bearing is formed on a separate inner ring engaged onto the wheel hub, irregularities are formed on the outer peripheral surface of the wheel hub, and radial expansion swaging of the wheel hub is used to cause the irregularities to bite into the inner peripheral surface of the inner ring, thereby fastening the wheel hub and the inner ring together through a plastic deformation section.
