Abstract
The object of the invention is to improve the performance over a period of time and ensure a constant pre-stressing force of the axial retaining device for a tripod homokinetic joint. For this purpose, surfaces carried by the tulip member, which act as bearing surfaces for part-spherical surfaces carried by the tripod of the joint, comprise recesses of concave shape and of a radius of curvature which is slightly larger than the radius of curvature of the part-spherical bearing surfaces carried by the tripod.
