A wheel assembly has a wheel with a hub. A rotation surface disposed in the hub has a bore. A sleeve insertable in the bore of the rotation surface has an outer surface with a circumferential groove and first and second opposite axial ends. The first axial end has a shoulder extending radially outward. A resilient ring disposed in the circumferential groove is compressible to a compression diameter sufficient to enable the sleeve to be inserted in the bore of the rotation surface. The resilient ring is expandable to an expansion diameter greater than the inner surface diameter of the bore of the rotation surface when unconstrained. The circumferential groove is spaced from the shoulder at a distance sufficient to enable the resilient ring to expand to the expansion diameter when the sleeve is inserted in the bore of the rotation surface and the shoulder is adjacent the rotation surface.

A bearing device for a vehicle wheel, which has an increased number of balls and in which the ease of mounting the balls is increased. The bearing device is configured such that each of the columns (7b) of the retainer (7) is provided with latch sections (7e) protruding toward adjacent columns (7b) and with cutouts. The front ends of the latches (7e) are located within an annular range having a radial width R1 defined between the outer peripheral circle of a ball (8) and a reference imaginary circle C1 having a diameter D1 centered on the center of the ball (8).

A wheel hub unit having a rotatable hub provided with an axially outer flange and a bearing unit. The bearing unit providing a radially outer ring, a radially inner ring and a plurality of rolling bodies positioned respectively between the radially outer ring and the hub and between the radially outer ring and the radially inner ring. The radially inner ring has a finished axial length which ensures a predetermined value of an axial preload of the bearing unit and a finished axial length is defined by the following formula: X=(X+X)X1

An in-wheel motor drive device (10) includes a wheel hub bearing unit (11) having an outer ring (13) , an inner ring (12) protruding from the outer ring to one side in an axial (O) direction, rolling elements (14) between the outer ring and the inner ring, and a fixing bolt (15) for fixing the outer ring to a non-rotary member (102); and a brake disk (55) having a connecting portion (58) configured to connect with one end of the inner ring, a cylindrical portion (57) extending from the connecting portion to the other side in the axial direction and disposed coaxially to the inner ring, and at least a part of the fixing bolt is received in an internal space of the cylindrical portion.

A wheel hub bearing for motor vehicles providing a hub and a bearing unit in turn comprising a radially outer ring, at least one radially inner ring, at least one crown of rolling bodies between the radially outer ring and the radially inner ring. The hub has a radial stiffening. The radial stiffening of the hub has a misalignment respect to a seat. Accordingly, a distance between a centerline axis of the seat of the radially inner ring on the hub and a center line of the radial stiffening, less than or equal to 25% of a length of the seat.

A bearing device 1 for a vehicle wheel, wherein an annular weir part 20 is provided on the outer periphery of an outer-side end part of an outer member 2, the annular weir part 20 having the rotation axis L of an inner member 3 as a center, the weir part 20 having a shape that is asymmetrical between the upper side Us and the lower side Ls of the outer member 2, and the weir part 20 being inclined farther toward the inner side the more a weir wall surface 20a faces outward in the radial direction in a part or all of the upper side Us. Also, the weir part 20 is inclined farther toward the outer side the more the weir wall surface 20a faces outward in the radial direction in a part or all of the lower side Ls.

A preload inspection method with which a preload value can be calculated more accurately. The preload inspection method for a wheel bearing device provided with an outer member having an outside raceway surface, an inner member having an inside raceway surface, and rolling bodies, is provided with: a power calculation step in which the outer member or the inner member is rotated in a relative manner and the power is calculated; a preload value calculation step in which a preload value is calculated on the basis of the power calculated in the power calculation step; and a pass/fail determination step is made on the basis of whether the preload value calculated in the preload value calculation step is within a permissible range.

A wheel end disconnect assembly includes an axle shaft, a wheel hub, and a wheel end disconnect clutch. The axle shaft has a first dog clutch spline and the wheel hub has a second dog clutch spline. The wheel end disconnect clutch has a dog clutch sleeve and a rocker pin. The dog clutch sleeve has a third dog clutch spline engaged with one of the first or second dog clutch splines and arranged to selectively engage and disengage from the other of the first or second dog clutch splines, and a first spiral groove. The rocker pin has a first pin end arranged to selectively engage and disengage from the first spiral groove to axially displace the dog clutch sleeve. The first dog clutch spline and the second dog clutch spline may both be outer splines, and the third dog clutch spline may be an inner spline.
