Abstract: A plunging type constant velocity universal joint has six torque transmission balls, and a curvature center of a spherical outer peripheral surface and a curvature center of a spherical inner peripheral surface of a cage are offset toward opposite sides in an axial direction with respect to a joint center. The plunging type constant velocity universal joint is used at a normal operating angle of from 8° to 12°. A ratio DBALL/DSPCD of a diameter (DBALL) of the torque transmission ball to a spline pitch circle diameter (DSPCD) of a coupling hole of an inner joint member is within a range of 0.80 to 0.86. A contact angle of the torque transmission ball and a linear track groove is within a range of 32° to 35°. A contact ratio of the torque transmission ball and the linear track groove is within a range of 1.05 to 1.08.

Abstract: A ball cage for universal use both in a cross-groove type plunging constant velocity joint and in a cross-groove type fixed constant velocity joint has an external contour with sections of different curvature. Axial edge sections of the external contour are designed as spherical sections located on the circumference of an imaginary sphere, whereas a center section of the external contour located axially between the edge sections runs radially inside the diameter of the imaginary sphere.

Abstract: A constant velocity joint includes an external joint part including internal ball tracks, an internal joint part including external ball tracks assigned to the internal ball tracks, and a ball cage holding balls. The external joint part is connectable to a connecting part and sealed by a closure cap on the side facing this connecting part. The internal joint part is an integral internal joint part connected permanently to a shaft piece, sealed on this side towards the external joint part by a flexible sealing element, hardened, and has a protruding welding attachment for an adapter on its free end. The welding attachment outer diameter is larger than the smallest integral internal joint part outer diameter. In a method, the sealing element is mounted over the integral internal joint part free end and connected to the external joint part, the adapter subsequently welded near the welding attachment.

Abstract: A constant velocity universal joint is assembled as a crown ball meshed within a housing socket for rotation about respective rotational axes. The outside diameter of the crown ball is greater than the inside diameter of the socket. A plurality of channels, equally spaced around the crown ball perimeter are cut into the crown ball surface generally along or parallel with the crown ball drive axis. An arcuate cup is cut into each crown ball channel to confine a respective torque transfer element. A number, corresponding to the number of crown ball channels, of partial cylinder channels are cut into the inside surface of the housing socket. One of opposite side walls for each housing channel is given an arcuate radius corresponding to that of the force transfer elements. Ridges between adjacent crown ball channels mesh with ridges between adjacent housing socket channels. Torque transfer elements confined within said crown ball cups engage the partial cylinder wall of the housing channels to transfer drive forces between the crown ball and socket housing through a departure angle between the respective rotational axes.

Abstract: A fixed type constant velocity universal joint is configured such that an axial offset amount of a curvature center of each track groove of an outer joint member and an axial offset amount of a curvature center of each track groove of an inner joint member are zero. Track grooves of the outer joint member are formed alternately in a circumferential direction to be inclined in mutually opposite directions with respect to an axis, and track grooves of the inner joint member are formed alternately in the circumferential direction to be inclined in mutually opposite directions with respect to the axis. An outer surface of the inner joint member is formed into a spherical surface which is held in slide-contact with an inner spherical surface of a cage. An inner surface of the outer joint member is formed into a cylindrical surface.

Abstract: There is provided an arrangement for mechanically and reliably joining a shell-type outer ring of a homokinetic joint and its shaft. A circular hole (4) is formed in a press formed end wall of an outer ring (1). A polygonal surface or serrated grooves are formed on the inner periphery of the hole (4). A protrusion (7) provided at one end of a shaft (5) is press-fitted in the hole (4) to join the outer ring and the shaft so that they will not rotate relative to each other. A caulking tool is used to deform protrusion (7) to form caulked portion (14) so that the outer ring (1) is prevented from moving axially relative to shaft (5).

Abstract: A constant velocity or homo-kinetic universal joint transferring torque through at least three ball members between inner and outer coupling members and held by a cage in a common plane bisecting the angle between the axes of thecoupling members. The radial dimension of the joint is kept at a minimum and the cage rides on spherical walls of the inner and outer coupling members and has circumferentially spaced, radial lugs increasing the guide surfaces of the cage windows. The cage is positioned normal to the open face of the outer coupling member, pushed into the coupling member, rotated circumferentially to align the lugs to fit into the grooves of the coupling member, and then rotated axially into the plane of the coupling member to hold the coupling members in fixed axial relation.
