Abstract: An assembly for driving and supporting a wheel has a wheel hub 20 and an outer joint member 31. The wheel hub 20 includes a flange 21 which connects the wheel 5 and the wheel hub 20 together. A constant velocity joint is rotatably supported on a wheel carrier 8 by a supporting means. The constant velocity joint is fixed for torque transmitting purposes and is rotatably supported about an axis by a rolling contact bearing 14 having two rows of rolling contact members 17, 18. Two inter-engaging sets of teeth 29, 29' secure the constant velocity joint to the wheel hub 20. The first set of teeth 29 moves axially in relation to the outer joint member 31 causing the second set of teeth 29' to be formed in a bore 33 within the outer joint member 31 during assembly.

Abstract: A constant velocity universal ball joint has a bell-shaped outer joint part which is open at one end. The outer joint part includes longitudinally extending circumferentially distributed outer ball tracks. An inner joint part with longitudinally extending circumferentially distributed inner ball tracks is positioned within the outer part such that the outer and inner tracks are arranged radially opposite one another to form pairs. A torque transmitting ball is received in each track pair. A cage is arranged between the outer joint part and the inner joint part and holds the balls in a common plane in circumferentially distributed cage windows. The cage guides the balls on to the angle bisecting plane when the axes of the outer and inner joint part are articulated relative to one another. The outer joint part is produced, especially by extrusion, forging or deep-drawing. The forming provides outer ball tracks which, if viewed from the open end, are axially undercut-free.

Abstract: An outer joint part consists of a casing in which the axially extending guiding tracks are fitted in the form of inserts. The casing is provided with axially extending continuous recesses which are open towards the inserts. The unique process for manufacturing the outer joint part consists of positioning the inserts within the recesses and holding them in position by welding or by utilizing a pressing operation on the exterior of the casing while simultaneously positioning the inserts using a supporting core.

Abstract: A constant velocity universal ball joint has an outer joint part, an inner joint part and torque transmitting balls held in a cage. The cage has centers of curvature (M.sub.1, M.sub.2) of the outer spherical face (14, 44) and of an inner spherical face (14, 44) of the ball cage (4, 34) which are axially offset relative to a central cage plane (E), defined by the circumferentially extending center lines (L.sub.m) of the cage windows (12, 42). The center of curvature (M.sub.1) of the outer spherical face (13, 43) is positioned towards the aperture (8, 38) in the outer joint part (2, 32), and the center of curvature (M.sub.2) of the inner spherical face, (14, 44), is positioned towards the end of the outer joint part (2, 32) located axially opposite the aperture (8, 38).

Abstract: A constant velocity fixed joint having an outer joint part, an inner joint part, a cage and torque transmitting balls has the cumulative clearance errors of the joint minimized via the fixing method of supporting inserts. This is achieved in that a ring is provided with at least two fingers pointing axially and radially inward into the cavity of the outer joint part and arranged between two outer running grooves so as to abut the spherical contact face of the cage. While the clearances between the internal joint components are positioned at a predetermined relationship, the ring is positioned at an axial distance from a reference face located at the open end of the outer joint part and that the ring, while observing a predetermined axial play, is connected to the outer joint part. The inner faces of the outer joint part arranged between the outer running grooves thus being held at a predetermined position relative to the spherical outer face of the cage.

Abstract: A homokinetic ball turning joint has a joint outer part (1a) with ball tracks (6a) distributed around its circumference that extend substantially in the longitudinal direction and a joint inner part (11a) with ball tracks (13a) distributed around its circumference that extend substantially in the longitudinal direction. The tracks (6a, 13a) are arranged in pairs, lie opposite each other in the radial direction and carry together a torque transmitting ball (14a). A cage (7a) receives the ball (14a) in windows (15a) distributed around the circumference, retains it in a common plane and when the axes of the joint outer part (1a) and joint inner part (11a) are bent towards each other, it guides the balls (14a) onto the angle bisecting plane. The joint outer part (1a) has inner surfaces (5a) with no undercuts located between the individual ball tracks (6a), when viewed in the axial direction.

Abstract: A constant velocity universal ball joint has an outer joint part and an inner joint part. Each part is provided with a plurality of ball tracks extending substantially in a longitudinal direction. The balls provide torque transmission and are guided in radially opposed tracks in the outer joint part and in the inner joint part. A cage with cage windows holds each ball in a plane positioned perpendicularly relative to the longitudinal axis. The cage includes a mechanism which, if the axes of the outer joint part and the inner joint part deviate from one another, guide the cage with the balls on to the angle-bisecting plane. Each of the track faces of the ball tracks, at the outer joint part and/or at the inner joint part, are subjected to loads by the balls, as well as each of the regions of the surfaces adjoining the ball tracks, which are guiding faces for the cage, undergo a hardening operation. Also, unhardened zones are provided between each two ball tracks between the guiding faces.

Abstract: An insertable unit for a wheel bearing has an integrated constant velocity universal joint, which is axially insertable into the wheel carrier from the outside and which permits easy dismantling and re-assembly. The outer joint part at the wheel end can be inserted through the through-bore of the wheel carrier. The outer bearing ring is inserted into the through-bore and is secured against axial displacement. The inner diameter of the two-part inner bearing ring is smaller than the outer diameter of the outer joint part. The outer joint part and the wheel hub are welded to one another in the region of the axially inner end of the two-part inner bearing ring, with the outer joint part being supported on the inner bearing ring by a planar face.

The outer part is non-rotatingly connected to a first driveshaft. An inner joint part is coupled with the outer joint part. The inner joint part has radial arms which engage the tracks and on which the rollers are rotatably and radially movably supported. The inner part is non-rotatingly connectable to a second driveshaft. The outer joint part further includes an outer annular member directly and firmly connected to the first driveshaft. Track elements directly guide the rollers, and resilient intermediate elements are arranged between the two parts. A mutual centering mechanism is provided between the annular member of the outer joint part.

Abstract: A constant velocity fixed joint has an inner joint part which is axially supported by a stop face located on the inside of the outer joint part. The movement of the cage is controlled via the balls and, to prevent any outward movement, the axial support of the inner joint part is limited to an annular region arranged at the open end of the hollow space of the outer joint part. The cage is arranged at a specified distance from the inner surface of the outer joint part and from the outer surface of the inner joint part.

Abstract: A constant velocity universal ball joint has a bell-shaped outer joint part which is open at one end. The outer joint part includes longitudinally extending circumferentially distributed outer ball tracks. An inner joint part with longitudinally extending circumferentially distributed inner ball tracks is positioned within the outer part such that the outer and inner tracks are arranged radially opposite one another to form pairs. A torque transmitting ball is received in each track pair. A cage is arranged between the outer joint part and the inner joint part and holds the balls in a common plane in circumferentially distributed cage windows. The cage guides the balls on to the angle bisecting plane when the axes of the outer and inner joint part are articulated relative to one another.

Abstract: A tripod joint has an outer joint part with three circumferentially distributed, axis-parallel recesses forming circumferentially distributed opposed tracks. An inner joint part has a star-shaped cross-section and three circumferentially distributed arms engaging the recesses in the outer joint part. The arms support roller assemblies. When torque is transmitted with the joint in an extended position, the resultant K.sub.1 of the forces acting from the inner joint part directly on a roller forms a shorter perpendicular distance from the joint axis than the resultant K.sub.2 of the counter forces acting from the outer joint part on the roller, so that, when torque is introduced into the joint, at any angle of articulation of the operating range, the roller is subject to a tilting moment.
