摘要： Six track grooves formed in a spherical inner peripheral surface of an outer joint member are each formed into an arc shape having a curvature center at a joint center. The track grooves are inclined in a circumferential direction of the outer joint member with respect to a joint axial line, and are adjacent to each other in the circumferential direction with their inclination directions opposite to each other. Six track grooves formed in a spherical outer peripheral surface of an inner joint member are formed so as to be mirror-image symmetrical with the track grooves paired therewith of the outer joint member with respect to a joint center plane at an operating angle of 0°. An inclination angle of each of the track grooves of the outer joint member with respect to the joint axial line is set to 8° or more and 16° or less.

摘要： A fixed type constant velocity universal joint of a track groove crossing type has track grooves of an inner joint member formed so as to be mirror-image symmetrical with the paired track grooves of an outer joint member with respect to a joint center plane at an operating angle of 0°. The track grooves of both the joint members each have a length corresponding to a maximum operating angle required for a rear-wheel drive shaft. Further, each axial clearance between the inner joint member and the cage is set larger than an axial clearance formed by a ball track clearance between each of balls and each track groove.

摘要： Provided is a fixed type constant velocity universal joint (1) of a track groove crossing type, in which track grooves (9) of an inner joint member (3) are formed so as to be mirror-image symmetrical with the paired track grooves (7) of an outer joint member (2) with respect to a joint center plane (P) at an operating angle of 0°. The track grooves (7, 9) of both the joint members (2, 3) each have a length corresponding to a maximum operating angle (θmax) required for a rear-wheel drive shaft. Further, each axial clearance (ΔSia1, ΔSia2) between the inner joint member (3) and the cage (5) is set larger than an axial clearance (ΔTao+ΔTai) formed by a ball track clearance (ΔT) between each of balls (4) and each track groove (7, 9).

摘要： Track grooves of an outer joint member include first and second track groove portions positioned on interior and opening sides, respectively. Each first track groove portion has an arc shape with a curvature center at a position offset to the opening side with respect to a joint center. The first track groove portions are inclined in a peripheral direction of the outer joint member with respect to a joint axial line and adjacent to each other in the peripheral direction with their inclination directions opposite to each other. Each second track groove portion has a shape that is different than each of the first track groove portions so as to increase an effective track length at a maximum operating angle. The second track groove portions are connected to the first track groove portions at a position on the opening side with respect to the joint center.
