Abstract

A constant velocity universal ball joint in the form of a plunging joint has an outer joint part provided with outer ball tracks which extend at a first angle of intersection +.gamma..sub.t relative to the longitudinal axis A.sub.a of the outer joint part. An inner joint part is provided with inner ball tracks which extend at a second angle of intersection -.gamma..sub.t relative to the longitudinal axis A.sub.i of the inner joint part. Torque transmitting balls are guided in outer and inner ball tracks associated with one another in pairs, with the angles of intersection +.gamma..sub.t, -.gamma..sub.t of tracks associated with one another in pairs relative to the longitudinal axes A.sub.a, A.sub.i of the respective joint part being of identical size and being set in opposite senses. A ball cage is positioned between the outer joint part and the inner joint part, and has circumferentially distributed cage windows holding the balls in a common plane. Each two circumferentially adjoining ball tracks in the outer joint part comprise center lines B which extend parallel relative to one another and are positioned in one plane and form outer pairs of tracks, and each two circumferentially adjoining ball tracks in the inner joint part comprise center lines C which extend parallel relative to one another and are positioned in one plane and form inner pairs of tracks.
