This bearing device 1 for a vehicle wheel is provided with: a magnetic encoder 7 provided to an inner-side end of an inner race 4, which is an inward member; a cover 11 for covering an inner-side opening 2B of an outer race 2, which is an outward member, the cover 11 having opened therein a sensor attachment hole 11H in which an opening 11A and a thin-walled bottom 11B are formed; and a magnetic sensor 9 disposed facing the magnetic encoder 7 across the bottom 11B, the magnetic sensor 9 being inserted into the sensor attachment hole 11H in the cover 11 through the opening 11A. The bottom 11B in the sensor attachment hole 11H is formed in such a shape as to bulge toward the inner side.

A speed measuring device for a wheel hub assembly equipped with a rolling bearing. The measuring device having an encoder wheel mounted on a rotating ring of the bearing, a mechanical support disposed between the encoder wheel and the ring to cause the encoder wheel and the ring to be angularly fixed to one another, and a mechanical lock for axially locking the encoder wheel in a seat formed by the mechanical lock together with the mechanical support. The encoder wheel is equipped with a base structure made of plastic material mounted in a seat.

The present invention relates to a boot assembly of a drive axle in which a bearing seal of a wheel bearing is removed to reduce drag torque and also reduce friction noise occurring in a wrinkled portion of the boot, and introduces a boot assembly of a drive axle configured to include: a wheel bearing assembled to a wheel housing; an outer ring formed in a ring shape and having an outer diameter part fixed to an outer wheel of the wheel bearing; a boot having a large diameter part of one end thereof, assembled to an inner diameter part of the outer ring; and a bearing seal unit assembled between a small diameter part of the other end thereof and a driveshaft by a band to prevent the introduction of foreign matter while restricting the rotation of the boot.

A speed measuring device for a wheel-hub unit provided with a rolling bearing, the measuring device having an encoder wheel made of magnetized elastic material and assembled on a rotating ring of the bearing; mechanical supporting means that are directly placed between the encoder wheel and the ring so that the encoder wheel and the ring are angularly constrained to each other; and mechanical locking means for axially locking the encoder wheel inside a seat defined by the mechanical locking means together with the mechanical supporting means.

In a thrust washer for the axial securing of rolling elements of a bearing, and a gear mechanism including a thrust washer, the thrust washer is arranged as a circular disk, which has an axially protruding, in particular radially outer, projection. The circular disk has a recess, which is disposed out of center, i.e., the center point of the, e.g., circular recess thus particularly being set apart from the center axis and/or from the center point of the circular disk. The projection may have an annular shape, and the ring axis is set apart from the center point of the, e.g., circular recess.

A bearing device for a shaft has at least two axially spaced-apart, radial anti-friction bearings with rolling bodies. In each of the anti-friction bearings, an inner race is formed for the rolling bodies on an inner bearing element which is connected fixedly to the shaft. An outer race is formed for the rolling bodies on an outer bearing sleeve having at least two bearing sleeve elements which are guided coaxially with respect to one another in a guide device. Each of the anti-friction bearings is assigned a separate bearing sleeve element with in each case one anti-friction bearing running surface. The guide device converts a rotation of at least one of the bearing sleeve elements about the shaft longitudinal axis into a spacing change of the two bearing sleeve elements. The axial spacing between the bearing sleeve elements can be adjusted and/or fixed and/or prestressed with spring element.

A motor vehicle drive wheel assembly comprising a fixed subassembly comprising two outer raceways; a rotating subassembly comprising a wheel hub, two inner raceways and two rows of rolling bodies that are arranged in two pitch planes PP1 and PP2. One of the inner raceways is formed on a rolling bearing ring that bears against a transmission bowl at an annular contact interface situated between the two pitch planes.

A method of manufacturing a hub unit bearing (1) includes the step of applying an axial load to a shaft end of a hub body (21) so that a staking portion (26) for inner races (22a, 22b) is formed in the hub body (21). The load is adjusted based on at least one of first information acquired before applying the load and second information acquired while applying the load.

A bearing device (1) for a vehicle wheel provided with: an outer member (2); and an inner member comprising a hub wheel (3), and at least one inner wheel (4) press-fitted into the small-diameter ridge (3A) of the hub wheel (3); wherein a belt-shaped part (2F) that radially protrudes by a protrusion amount (P1) is formed over a prescribed width (W1) in the outer peripheral surface of the outer member (2) so that at least part of the belt-shaped part (2F) radially overlaps the outside rolling surface (2D) which is on the vehicle-wheel-attachment-flange-facing side of the outer member (2). The present invention addresses the problem of providing a bearing device for a vehicle wheel in which the amount of deformation in an opening of an outer member can be reduced and decreases in rolling fatigue service life can be prevented while keeping overall weight increase to a minimum.

A method for producing a composite rolling bearing (1) having a bearing flange (3) and at least one rolling bearing (4, 5) held on the bearing flange (3) by an inner ring (6, 7). In order to be able to fix the inner ring (7) on the bearing flange (3) with axial preloading without expansion, the inner ring (7) is acted upon by a holding-down device (23) that radially holds down the inner ring (7) and is preloaded against the inner ring (7) by a regulated axial force (F), and, by way of an advancing cone (21) introduced radially on the inside axially into the bearing flange (3), material (11) present on the bearing flange (3) is displaced radially towards the outside into a recessed formation (15, 16) in the inner ring (7).
