Abstract: 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.

Abstract: A fixed center constant velocity joint includes a first group of funnels and a second group of funnels arranged radially about a longitudinal axis in alternating relationship. The first group of funnels diverges in a first direction and the second group of funnels diverges in a second direction opposite the first direction along the longitudinal axis. The first group of funnels defines a first diverging width increasing in value along the longitudinal axis and the second group of funnels defines a second diverging width increasing in value at a different rate than the first diverging width to bias the joint in one of the first direction and the second direction.
