A subassembly includes a wheel hub and a constant velocity joint having a bell in which the wheel hub is connected to the bell by friction welding. A first one of the wheel hub and the bell may include an axial projection and the other one of the wheel hub and the bell may include a recess in which the axial projection is received. Also a method of connecting a wheel hub to a constant velocity joint by friction welding.

A subassembly includes a wheel hub and a constant velocity joint. The constant velocity joint includes a bell and the wheel hub is connected to the bell by high-pressure internal forming. Preferably, the wheel hub includes an axial projection disposed radially inside a connecting section of the bell, the projection interacting with the connecting section during the high-pressure internal forming process in order to connect the wheel hub to the bell. The projection is preferably configured to deform plastically and is connected to the bell in an interference-fit manner. Further, the wheel hub preferably provides an inner ring of a bearing unit and either the bell of the constant velocity joint provides another inner ring or a separate inner ring is disposed between the wheel hub and the bell.

A spline connection having a hub with a toothing profile on the inner circumference, an axle journal having a toothing profile on an outer circumferential portion, a shoulder for axial support and/or abutment against the hub, and a tensioning device for axially bracing the axle journal with the hub. The hub has a constant toothing profile and the axle journal has a first portion and a second portion with different toothing profiles. The first portion is arranged on the insertion side to be further away from the shoulder than the second portion and has a constant toothing profile with play with respect to the toothing profile of the hub. The second portion is arranged on the shoulder side and has a toothing profile which has reduced tooth spaces compared with the first portion and which is play-free with respect to the toothing profile of the hub.

An axle assembly for drive wheels of vehicles includes a steering knuckle, an axle housing coupled to an inside of the steering knuckle, a wheel disc that is fixed to the axle housing to be rotatable integrally with the axle housing, and a drive shaft that is coupled to the axle housing to be rotatable integrally with the axle housing. A hub bearing is disposed between the steering knuckle and the axle housing. A forming part is formed at an end of the axle housing in a state in which a bearing inner race of the hub bearing is coupled to an outer circumferential surface of the axle housing, and the bearing inner race is engaged with a side part of the axle housing by the forming part in a state in which the forming part is pressed against a side end of the bearing inner race.

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 face spline coupling for transmitting torque between a wheel end unit and a driven shaft arranged in a longitudinal axis of a drive-wheel arrangement for a motor vehicle includes a first face spline formed in the wheel end unit and a second face spline formed in the driven shaft. The first face spline is generally perpendicular to the longitudinal axis and faces the driven shaft, and the second face spline is also generally perpendicular to the longitudinal axis and faces the wheel end unit. The first and second face splines are meshed together and detachably coupled by inter-fitting teeth of each of the first and second face splines. In addition, the teeth in each of the first and second face splines are formed in a helical configuration.

A bearing device includes a bearing having an outer race with double-row outer raceway surfaces formed on its inner periphery, a hub wheel and an inner race having double-row inner raceway surfaces formed on outer peripheries thereof opposed to the outer raceway surfaces, and double-row rolling elements interposed between the outer and inner raceway surfaces. The bearing has a constant velocity universal joint separably coupled thereto with a screw fastening structure, in which a stem section of an outer joint member of the constant velocity universal joint is fitted to an inner diameter portion of the hub wheel, and in which a plurality of convex portions extending in an axial direction are formed on the stem section, and a plurality of concave portions having an interference with respect to only circumferential side wall portions of each of the plurality of convex portions are formed on the hub wheel.

An apparatus for transferring driving force at a wheel for a vehicle may include a housing of a constant velocity joint having a center of a first end portion formed to be penetrated and inserted into a hub bearing, and a step formed on an inner peripheral surface of a middle portion of the housing, a hub flange supporting an expansion part by the step by having one end portion coupled to a wheel side and another end portion inserted into the housing to thereby form the expansion part expanded in a radial direction, and a forming member installed in the housing to face the expansion part and having an outer peripheral surface supported by an inner peripheral surface of the housing.

A wheel-end disconnect assembly for translating rotational torque between an output shaft and a wheel hub of a vehicle driveline. A knuckle bracket at least partially supports the wheel hub. A clutch is operatively attached to the knuckle bracket, is disposed in selective torque translating relationship between the output shaft and the wheel hub, and is movable between: an engaged configuration wherein torque is translated between the output shaft and the wheel hub, and a disengaged configuration wherein torque is interrupted. An electromagnetic actuator is provided and has a slider selectively movable between a first stable position and a second stable position. The actuator is disposed in force translating relationship with the clutch such that movement from one stable position to the other stable position causes corresponding movement of the clutch between the configurations so as to selectively translate rotational torque between the output shaft and the wheel hub.

A constant velocity joint for a vehicle includes: an axle housing fixed to a knuckle by a hub bearing; a joint assembly inserted into an inner diameter portion of the axle housing and configured to transmit power from a shaft to the axle housing through a plurality of joint balls; an extension portion formed by deforming an end portion of the axle housing on an inward side of a vehicle body to extend in a radial direction of the axle housing so as to provide a pressing force to an inner race of the hub bearing in an axial direction of the axle housing; and a boot having one side surrounding an outer side of the extension portion to be coupled to the extension portion so as to form a restraining force between the extension portion and the boot in the axial direction.
