A fixed constant velocity universal ball joint has an outer joint part with an inner aperture including substantially longitudinally extending outer ball tracks. An inner joint part forms a hub member positioned in the inner aperture of the outer joint part. The inner joint part includes substantially longitudinally extending inner ball tracks. Torque transmitting balls are guided in outer and inner ball tracks associated with one another in pairs. The ball tracks are curved in the longitudinal direction. An annular ball cage is positioned between the outer joint part and inner joint part. The cage includes circumferentially distributed cage windows which hold the balls in a common plane and guide the balls onto an angle bisecting plane when the joint is articulated. The ball tracks are asymmetric in section. The outer track pairs of two adjoining outer ball tracks are formed in the outer joint part. The outer ball tracks extend parallel relative to one another. The inner track pairs of two adjoining inner ball tracks are formed in the inner joint part. The inner ball tracks extend parallel relative to one another. The respective outer and inner track pairs are associated with one another.

A fixed constant velocity universal ball joint comprising: an outer joint part to be connected to a first drive part, an inner aperture in said outer joint part, said aperture provided with substantially longitudinally extending curved outer ball tracks; an inner joint part to be connected to a second drive part and which forms a hub member positioned in the inner aperture of the outer joint part, said inner joint part provided with substantially longitudinally extending ball tracks, said outer and inner ball tracks each defining center lines; torque transmitting balls guided in outer and inner ball tracks associated with one another in pairs, said ball tracks being curved in the longitudinal direction; planes through said curved center lines dividing the outer and inner ball tracks into track halves respectively; an annular ball cage arranged between the outer joint part and inner joint part, said cage including circumferentially distributed cage windows which hold said balls between axial stops in a common plane and guide said balls onto an angle-bisecting plane between intersecting axes of the outer joint part and inner joint part when the joint is articulated; said outer and inner ball tracks, associated with one another for accommodating one of said torque transmitting balls, carry the balls via respective track halves positioned circumferentially on opposed sides of said planes and adjoining outer ball tracks and adjoining inner ball tracks, respectively, carry the balls via track halves positioned on circumferentially alternating sides of said planes, with each pair of outer and inner ball tracks associated with one another for accommodating one of said torque transmitting balls being asymmetric in cross section; outer track pairs in the outer joint part are formed by two respective adjoining outer ball tracks with their center lines extending parallel relative to one another, and inner track pairs in the inner joint part are formed by two respective adjoining inner ball tracks with their center lines extending parallel relative to one another, with respective outer and inner track pairs being associated with one another.
