摘要： A corrugated portion is formed in one end edge portion of the metallic shaft main body (2), and a triangular corrugated portion (11) is formed in an end edge portion of the shaft auxiliary body (3) on the metallic shaft main body side. The metallic shaft main body (2) and the shaft auxiliary body (3) are integrated by being linearly arranged by way of meshing that brings a side of the triangular corrugated portion (9) on the main body side and a side of the triangular corrugated portion (11) on the auxiliary body side into contact with each other. A fiber orientation angle (θ) of the fiber reinforced plastic of the shaft auxiliary body (3) is set so as to be in the same direction as a direction of stress generated in a hypotenuse of each triangular portion under a torque load state.

摘要： Provided is a constant velocity universal joint having track shapes which facilitate quality control on a forging die set and products as in a conventional case while securing higher durability through securement of a stable contact state of forging-molded tracks and finishing-processed tracks with respect to balls. At least one of each of track grooves (22) of an outer joint member (23) and each of track grooves (25) of an inner joint member (26) is formed by cold-forging finishing. A track groove bottom side of the at least one of each of the track grooves (22) and the track grooves (25) is formed into a Gothic arch shape in horizontal cross-section, and track groove opening sides of the at least one of each of the track grooves (22) and the track grooves (25) are each formed into an elliptical shape in horizontal cross-section.

摘要： 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.

摘要： Provided is a fixed type constant velocity universal joint capable of securing a ball groove depth larger in comparison with that of conventional products and enhancing performance without an increase in a "force of pushing out balls in an axial direction", the force having an influence on joint efficiency. A ratio (F/PCR) of an offset amount F to a length (PCR) of a segment connecting the center of each of the guide grooves (22, 25) and a center of each of balls (27) to each other ranges from 0.045 to 0.065. A ratio (αt/α) ranges from 0.045 to 0.065 on a premise that an angle formed between the following is αt: a segment connecting a center of an outer surface of a retainer (28) and the center of each of the balls to each other; and the segment connecting the center of each of the guide grooves of the outer joint member and the center of each of the balls to each other, that an angle formed between the following is αc: a line connecting the center of the outer surface of the retainer and the center of each of the balls to each other; and a line connecting a joint center and the center of each of the balls to each other, and that a total of the angles is α.
