Abstract
A joint comprises a tripod element connected to a wheel shaft and provided with three trunnions on which are mounted rollers received in runways formed in a tulip element connected to a driving shaft. A mushroom element disposed in the tripod element bears against the tulip element, and a muzzle element axially retains the tripod element against the tulip element. The radius of curvature of the spherical dome of the mushroom element and/or of the tripod element is such that its center of curvature is offset toward the spherical dome relative to the axial plane of the tripod element. This arrangement eliminates vibrations and seizure which are liable to occur for intermediate angles of operation of the joint.
