Abstract
A non-plunging constant velocity ratio universal joint comprising outer and inner joint members (1, 2) with groove pairs (7, 8) in meridian planes and a cage (13) having apertures wherein torque-transmitting balls (9) are received on in each facing pair of grooves, has groove center lines which comprise portions with centers of curvature (M.sub.ag, M.sub.ak, M.sub.ig, M.sub.ik) which, with the joint in the aligned position, are disposed symmetrically relative to each other on opposite sides of the joint center plane (E.sub.K), and in the case of which the center lines of the grooves each comprise a portion with a narrower curvature on that side of the ball center plane (E.sub.K) to which the respective offset line (O.sub.A, O.sub.B) of the joint member points, as well as a portion with a wider curvature on the side of the ball center plane (E.sub.K) positioned opposite the respective offset line of the joint member.
