A low spring rate multi-convoluted collapsible spacer adapted for use as a bearing preloading element. The collapsible spacer comprises a substantially tubular body compressible in an axial direction thereof from a predetermined free length to a substantially shorter length. The tubular body includes a yielding zone and an elastic zone adjacent to said yielding zone. Each of the yielding and elastic zones has at least one convolution curved in the same radial direction. An average thickness of the body of the spacer in the elastic zone is substantially greater than an average thickness of the body in the yielding zone that provides the collapsible spacer a substantially higher resiliency in the axial direction in the elastic zone than in the yielding zone. As a whole, the collapsible spacer has a relatively low spring rate, thus larger amount of “spring back”, hence less sensitivity to wear and maladjustment.

A differential allowing relatively easy alignment and secure positioning of bearings is provided. The differential includes a differential carrier and a differential case disposed within the carrier. A bearing assembly is located between the differential carrier and the differential case and allows the differential case to rotate within the differential carrier. The differential carrier and a cup of the bearing assembly having mating threads allowing relatively easy alignment of the bearing assembly within the differential. A deformable member is attached to the bearing assembly cup and is deformed and inserted into a slot in the differential carrier upon alignment of the bearing assembly to securely position the bearing assembly.

A radial-axial bearing assembly made up of a radial cylinder roller bearing (1) and a thrust cylinder roller bearing (2) characterized in that a radially inwards directed flange (10) of an outer ring (3) of the radial cylinder roller bearing (1) is arranged between the radial cylinder roller bearing (1) and the thrust cylinder roller bearing (2) and thus defines a first raceway (19) for the thrust cylinder roller bearing (2), a first bearing washer (16) is arranged between two cylinder roller crown rings (12, 13) of the thrust cylinder rcller bearing (2) and defines a second and a third raceway (20, 21) for the thrust cylinder roller bearing (2) while a second bearing washer (17) defines a fourth raceway (22) therefor, said second bearing washer (17) being connected to the outer ring (3) of the radial cylinder roller bearing (1) by fixing screws (18) whereby a self-retaining combined radial-axial bearing is formed whose pre-stress can be adjusted by the manufacturer through the axial dimension of the first bearing washer (16).

A hub (2) includes a spindle (14) which projects through a housing (4) and rotates relative to the housing (4) on a bearing (6) that is located between the spindle (14) and the housing (4). The bearing (6) has two sets of raceways (28,40) that are oblique to the axis x, and in addition rolling elements (36) arranged in two rows between the sets of raceways (28,40). The inner raceways (28) that fit around the spindle (14) and have back faces (32), with the back face (32) for one of the races (26) being against a shoulder (18) from which the spindle (14) projects. Initially, the end of the spindle (14) projects straight beyond the back face (32) of the outer race—indeed, so that the races (26) can be installed over the spindle (14). But once the housing (4) and races (26) are in a position around the spindle (14), the projecting end portion of the spindle (14) is deformed radially and axially in a rotary forming operation such that it transforms into a formed end (20) that lies behind back face (32) of the race (26). With the two races (26) between the formed end (20) and the shoulder (18). During the rotary forming operation the hub (26) rotates, and the end of its spindle (14) is forced against a rotating forming tool and the force is monitored. The housing (4) is restrained and the torque transferred from the rotating hub (2) to the housing (4) is monitored.

A bearing assembly for a vehicle hub comprises rolling elements (9, 10) which are in rolling contact with at least one inner raceway (2) and outer raceway (1), of respectively an inner ring member and an outer ring member, one of which ring members comprises two bearing rings (3, 4) which are interconnected by means of a mounting sleeve (14) for preloading the rolling elements in axial direction between the raceways. The bearing rings (3, 4) are bonded to the sleeve (14) by means of glueing.

A hub assembly includes a hub having a spindle with a flange and a shoulder at one end of the spindle and a formed end turned outwardly at the other end of the spindle. In addition, the hub assembly includes a bearing having two cones set end to end and an outer race in the form of a housing located around the cones, and tapered rollers arranged in two rows between the outer race and cones. Initially the formed end of the spindle exists as an axially directed end portion of the spindle. The bearing is installed over this end portion and moved further along the spindle to bring the back face of one of its cones against the shoulder on the flange. The back face of the other cone lies at the end of a spline that leads out to the end portion on the spindle. A coupler ring having exterior and interior splines is installed over the spindle end porotion with its interior spline engaged with the spindle spline. Thereupon a circular clip is installed over the skpindle end portion and brought against the end of the interior spline on the coupler ring. The clip has circular cross-section, and this presents a contoured surface of generous radius beyond the interior spline. Finally, by rotary forming the spindle end portion is deformed over the contoured surface of the clip and against the end face of the coupler ring to create the formed end, so that the coupler ring and cone of the bearing lie captured between the formed end and the shoulder. Torque is transferred to the hub through the coupler ring when the ring is engaged with a drive train.
