Abstract: A constant velocity joint assembly includes an outer joint member defining a first longitudinal axis and including a closed end, an open end, a first set of outer tracks extending at least partially between the closed end and the open end, and a second set of outer tracks extending at least partially between the closed end and the open end. The assembly also includes an inner joint member defining a second longitudinal axis coaxial with the first longitudinal axis and including a first set of inner tracks and a second set of inner tracks, the inner joint including an attachment feature to receive a driveshaft. A path followed by the center of a ball in the first set of tracks is constrained by an outer race track path and an inner race track path, the outer race track path being a piecewise continuous function.

Abstract: A constant-velocity universal joint including a generally cup-shaped outer joint member and an inner joint member that define first and second groove portions. A pinch angle by which a ball is pinched in the first groove portion is open toward an opening of the outer joint member. A pinch angle by which the ball is pinched in the second groove is open toward a bottom of the outer joint member. An absolute value of the pinch angle in a larger-pinch-angle groove portion that is one of the first and second groove portions, is larger than an absolute value of the pinch angle in a smaller-pinch-angle groove portion that is the other of the first and second groove portions in a reference state. A radial clearance in the smaller-pinch-angle groove portion is larger than a radial clearance in the larger-pinch-angle groove portion when torque is not transmitted in the reference state.

Abstract: An outer joint member includes a cutout portion that is formed at least at each corner portion on an opening side of a cup section, which is defined between a radially inner opening end portion of each of track grooves and a radially inner spherical surface portion formed between the track grooves. The cutout portion is configured to prevent a cage from interfering with the outer joint member when the cage is incorporated into the outer joint member. The cutout portion and the track grooves of the outer joint member are finished by cold-forging ironing using a single ironing punch.

Abstract: A bearing device for a wheel has a hub wheel and a constant velocity universal joint with an outer joint member. Projecting portions extending in an axial direction are provided on one of an outer surface of a shaft section of the outer joint member and an inner surface of a hole portion of the hub wheel. The projecting portions are press-fitted into the other along the axial direction, and recessed portions are formed in the other through press-fitting of the projecting portions. Thus, a recess-projection fitting structure is formed, in which the projecting portions and the recessed portions are held in close contact with each other through an entire region of fitting contact regions therebetween.

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. 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.

Abstract: An axial fixation of a splined shaft connection, particularly between a hub of a constant velocity joint and a shaft, whereby a splined end of the shaft is to be inserted in and extracted out of a splined bore of the hub from one side thereof. A snap ring is in contact with a stop surface of the shaft and a holding surface of groove in the hub. The snap ring and the holding surface are situated in the extraction direction axially behind the carrying zone of the splines, whereby the hub is provided with an opening following the holding surface having a radius which is greater than the radius of the radially-opposed portion of the shaft by an amount which is at least equal to the radial width of the snap ring.

Abstract: A constant velocity joint (2) with a connecting shaft (4). The inner part (12) of the constant velocity joint (2) includes a through-bore (28) with a first portion in the form of inner teeth (29) and a second bore portion in the form of a circular-cylindrical bore portion (32). A coupling sleeve is inserted into the inner part (12). The coupling sleeve (33) includes outer teeth (34) which engage the inner teeth (29). These are followed by a circular-cylindrical portion (35) centered in the bore portion (32). The coupling sleeve (33), on its inner face, has first longitudinal grooves (37) arranged opposite second longitudinal grooves (39) of the connecting shaft (4). Rolling-contact members (40) are received between the first and second longitudinal grooves and are held so as to be guided in a cage. Members (40) serve to transmit torque between the coupling sleeve (33) and the connecting shaft (4) and enable a linear adjustment between the coupling sleeve (33) and the connecting shaft (4). By separating the inner part (12) from the coupling sleeve (33), production of the inner part is improved and it is possible to divide the joint function into a plunging movement and angular movement.
