摘要： Wedge angles are formed between mutually facing central track-groove portions (11b, 12b, 21b, 22b) of an outer joint member (1) and an inner joint member (2). Track grooves (11, 12) provided to the outer joint member (1) and track grooves (21, 22) provided to the inner joint member (2) include a first pair of track grooves (11, 21) respectively including the central track-groove portions (11b, 21b) forming therebetween the wedge angle (α) opening to an opening side of the outer joint member (1) under a state in which an operating angle is 0°, and a second pair of track grooves (12, 22) respectively including the central track-groove portions (12b, 22b) oppositely forming therebetween the wedge angle (β) opening to an inner-end side of the outer joint member (1) under the state in which the operating angle is 0° . Both the first track groove (11) and the second track groove (12) of the outer joint member (1) include opening-side track-groove portions (11c, 12c) connected respectively to the central track-groove portions (11b, 12b) directly, each of the opening-side track-groove portions (11c, 12c) being formed in such a shape as to be free from an undercut toward the opening side. Accordingly, it is possible to manufacture at low cost a high-efficient fixed type constant velocity universal joint which involves less torque loss.

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： A fixed type constant velocity universal joint prevents heat generation when a high load is applied or during high-speed rotation to improve durability, and suppresses a contact resistance between a cage and inner and outer races to improve constant velocity performance. Curvature centers of track grooves of outer and inner joint members have an offset of 0 in an axial direction. Track grooves of the outer and inner joint members, which are tilted in opposite directions from each other with respect to an axis line, are alternately formed in a circumferential direction. An outer surface of the inner joint member is a spherical surface to be brought into sliding contact with an inner spherical surface of the cage. An inner surface of the outer joint member is a cylindrical surface.

摘要： The present invention provides a fixed constant velocity universal joint that can be made compact, has little decrease in load capacity even when the fixed constant velocity universal joint is made compact and is at an operating angle, and can improve high angle strength and durability through lessening instances in which a ball runs over a track at a high angle. In the fixed constant velocity universal joint of the present invention, a cage 28 includes four pockets 29, the pockets 29 being a pair of long pockets 30 of which a circumferential direction spacing is wide and a pair of short pockets 31 of which the circumferential direction spacing is narrow. The pair of long pockets 30 are shifted by 180 degrees along a circumferential direction and a pair of short pockets 31 are shifted by 180 degrees along the circumferential direction. As a result, the long pockets 30 and the short pockets 31 are alternately disposed along the circumferential direction. A long pocket 30 houses two balls 27. A short pocket 31 houses one ball. Two ball housing sections 38 connected by a slit 37 are formed in the long pocket 30 by projections 36 that project towards a long pocket inner side being provided on opposing long sides 35 of the long pocket 30.
