A constant velocity fixed joint having an outer and inner joint part forming pairs of ball tracks, wherein the track base lines of the pairs of tracks each form an opening angle relative to one another. The track base lines of the outer ball tracks, at the attaching part end, form a radius whose center is positioned beyond a first longitudinal axis and is offset by a first offset from the central plane of the outer joint part towards the attaching part. The track base lines of the inner ball tracks, at the aperture end, comprise a radius whose center is positioned beyond the second longitudinal axis and is offset by a second offset from the central plane of the inner joint part towards the aperture.

Constant velocity fixed joint

A constant velocity fixed joint having an outer and inner joint part forming pairs of ball tracks, wherein the track base lines of the pairs of tracks each form an opening angle relative to one another. The track base lines of the outer ball tracks, at the attaching part end, form a radius whose center is positioned on a first longitudinal axis and is offset by a first offset from the central plane of the outer joint part towards the attaching part. The track base lines of the inner ball tracks, at the aperture end, comprise a radius whose center is positioned on the second longitudinal axis and is offset by a second offset from the central plane of the inner joint part towards the aperture.

A counter track joint including first pairs of tracks whose control angles open in a first axial direction, and second pairs of tracks whose control angles open in a second axial direction. The outer joint part forms an introducing aperture for the ball cage. The ball cage, while engaging the outer tracks, can be threaded into the outer joint part in the second axial direction. The outer joint part forms a first stop and guiding face for a spherical outer face of the ball cage. Between the introducing aperture and the first stop and guiding face, the outer joint part comprises a displacement region for the ball cage. A securing element forms a second stop and guiding face for the spherical outer face of the ball cage.

Constant velocity fixed ball joint in the form of a counter-track joint

A constant velocity fixed ball joint in the form of a counter track joint, having an outer joint part with outer tracks, an inner joint part with inner tracks, torque transmitting balls received in pairs of tracks formed of outer tracks and inner tracks, and a ball cage with cage windows in which the balls are held in a common plane and guided on to the angle-bisecting plane when the joint is articulated. First outer tracks, together with first inner tracks, form first pairs of tracks whose control angles open in a first axial direction. Second outer tracks, together with second inner tracks, form second pairs of tracks whose control angles open in a second axial direction, with the control angles being defined as angles between the tangents at the ball contact points in the tracks when the joint is in the aligned condition. The outer joint part forms a first stop-and-guiding face for a spherical outer face of the ball cage. A securing element at the outer joint part forms a second stop-and-guiding face for the spherical outer face of the ball cage. The inner face of the outer joint is undercut-free if viewed in the second axial direction.

Constant velocity fixed ball joint as a counter track joint

The invention relates to a constant velocity fixed joint and to the introduction of the cage into the outer joint part of a constant velocity fixed joint. The joint comprises an outer joint part, an inner joint part, a ball cage and balls. The outer joint part forms a bell-shaped member comprising a first longitudinal axis, a base, an aperture and circumferentially alternating first and second outer ball tracks. The inner joint part forms a hub comprising a second longitudinal axis and circumferentially alternating first and second inner ball tracks. The first outer and first inner ball tracks, together form first track pairs and the second outer and second inner ball tracks, together, form second track pairs. Each track pair accommodates a torque transmitting ball, with the tangents at the balls in the points of contact with the track pairs forming control angles. The first track pairs form control angles which open towards the aperture in the outer joint part and the second track pairs form control angles which open towards the base of the outer joint part. The outer joint part comprises a substantially internally spherical guiding face which is widened by two recesses which start from the joint aperture and extend into the joint interior.

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. Inner faces are positioned between the outer ball tracks. The outer part includes wall regions which start from the open end, are axially limited, are deformed radially inwardly, and are arranged between two outer ball tracks. The wall regions, whose width is smaller than the circumferentially directed distance between the respective outer ball tracks, are deformed. The deformed wall regions each form cage guiding faces positioned between the outer ball tracks and provide support towards the open end.

Constant velocity universal ball joint and method of producing such a

An outer joint part is produced by forming in such a way that the torque transmitting capacity is substantially increased and that the production costs, essentially do not rise. This is achieved in that at the outwardly open axial end of the cavity of the outer joint part, there is arranged a radially outwardly directed collar-shaped flange.

Constant velocity universal joint

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). The diameter of the inner aperture (15, 45) of the ball cage (4, 34), which is positioned towards the aperture (8, 38) of the outer joint part (2, 32), is greater than the greatest outer diameter of the surface (19, 49) of the inner joint part (3, 43).

Constant velocity universal ball joint with co-axial insertable inner

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. A method is provided which substantially facilitates handling while individual supporting inserts are attached and which allows the joint play to be set in the specified way. This is achieved in that the outer joint part is provided with recesses arranged between the outer running grooves. Wedge-shaped inserts serving to axially secure the cage and being connected to one another by an annular strip are inserted into the recesses. The wedge-shaped inserts are welded to the recesses and after the welding operation the annular strip between the wedge-shaped supporting inserts is removed.

Method of assembling constant velocity fixed joint

Constant velocity universal ball joint with cage securing elements

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.

Insertable unit for a bearing assembly

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.
