Abstract: A plurality of rollers is positioned between side members of a longitudinally-split, two-piece bearing race and a backup member that supports the two-piece bearing race along the length of side members. The backup member has angled surfaces such that ends of the rollers are closer to the angled surfaces than are intermediate portions of the roller. The two side members of the two-piece bearing race may be spread apart such that the angled surfaces of the backup member direct the side members of the two-piece bearing race toward the rollers to decrease the roller clearance and to create a preload.

Abstract: Rollers are aligned radially within a bearing cage, for rolling contact with a first thrust washer concentric with the bearing cage. The first thrust washer has a flat raceway portion and a curled portion that wraps around a portion of the bearing cage to retain the bearing cage and the first thrust washer together as an assembly. The curled portion includes a rim that extends radially 360 degrees with respect to the axis of the thrust washer and has a folded configuration such that a doubled portion is offset with respect to an axial midpoint of the thrust bearing to prevent the thrust bearing from being installed with a reversed orientation.

Abstract: Two lines of magnets have the same length and are aligned side by side. The lines of magnets have different numbers of magnetic pole pairs and have equal line lengths. A first sensor determines a relative position between poles of a pole pair of the first line of magnets, and a second sensor determines a relative position between poles of a pole pair of the second line of magnets. A circuit compares the relative positions determined by the sensors to determine an absolute position of the first line of magnets.

Abstract: A linear roller bearing includes a bearing cage retaining parallel rollers in a linear configuration. Side portions of the bearing cage extend laterally to form a mechanical interlock with an adjacent similar bearing cage such that, when two or more bearing cages are positioned about an inner tubular member for guided axial movement relative to a coaxial outer tubular member, the mechanical interlock prevents relative axial movement of the adjacent bearing cages. Adjacent bearing cages may be identical or of differing configuration provided a mechanical interlock preventing relative axial movement results. The linear roller bearing may include inner and outer races, or, alternatively, the tubular members may be formed with integral raceways.

Abstract: A unit consisting of a bearing equipped with a data sensor device and a housing in which the bearing is coupled. The bearing consists of an inner turning collar designed to be attached to a turning body, an outer fixed collar coupled to the housing, and rolling bodies positioned between them. The data sensor device consists of a coder that generates magnetic impulses attached to the turning collar and, attached to the fixed collar, a sensor equipped with at least two sensitive components capable of detecting such impulses. The housing is designed to permit said bearing to be locked radially and to lock the bearing axially in one direction.

Abstract: A needle bearing cup includes an inner bearing cup having an inner surface which forms a rolling element raceway and an outer bearing cup disposed about the periphery of the inner bearing cup having a length greater than a length of the inner bearing cup to form a lip. The lip of the outer bearing cup is then formed to retain rolling elements within the inner bearing cup. Preferably, the rolling elements are needle rollers and the inner bearing cup is secured to an outer bearing cup by mechanical lock in the form of a protruding portion extending from the outer bearing cup. The bearing cup may be double drawn with first and second sheet metal blanks forming the inner and outer bearing cups.

Abstract: A strip of metal is wrapped into a ring configuration such that ends of the strip are positioned in a predetermined relationship to each other. The ends of the strip are attached together by a temporary weld joining the two ends of the strip, thereby forming a temporary continuous ring. After heat treating the temporary continuous ring, the ring is separated at the temporary weld to provide a heat treated split bearing ring with a controlled clearance at the split.

Abstract: An annular casing partially encloses the outer race of a pair of the angular contact bearings. The casing is split along a radial plane into two casing halves, each casing half being molded of a polymer. The two casing halves are retained axially such that relative axial movement of the angular contact bearings is limited.

Abstract: Device for the analogue measurement of a torsion torque, steering column and module comprising it.

Abstract: A device for measuring torsional couple on a mechanical element, which includes two magnetic field generators attached in a first plane of the mechanical element and two magnetic field detectors arranged in a second parallel plane offset with respect to the first plane. The magnetic field detectors are attached on a support having two housings facing the magnetic field generators and which receive sensor elements on which the magnetic field detectors are attached. The shape of the housings is suited so as to allow movement of the sensor elements in such a way as to make possible an adjustment of an initial position of a sensitive element of each magnetic field detector on the support.

Abstract: Two external rings and an internal ring form an assembly that is connected to a column so it rotates with it, to which column the torque to be measured is applied. Elastically deformable members connect the internal ring to one external ring, and the other external ring remaining essentially unstressed. A measurement device, such as, for example, a probe having at least one with Hall effect device, measures relative displacement of the two external rings to determine the torque applied. The invention also concerns the steering devices equipped with such torque sensors, for example, for power or assisted steering.

At least one ball is positioned between the first and second cam plates, in the grooves of the first and second cam plates. The ball is biased radially to ensure that the ball follows the non-circumferential ball ramps of both cam plates in response to relative rotation of the two cam plates.
