ABSTRACT:
In a joint, each arm (22) of a tripod element (14) is provided with two rolling elements (24) disposed on opposite sides of the arm. According to the invention, each rolling element (24) has a spherical rolling surface (32) and a conical rolling surface (34) which respectively cooperate with a spherical surface (38) of the bowl element (20) and a conical surface (40) of a web (32) of the bowl element. Each rolling element (24) is mounted on the arm (22) by means of a half bush (54) which allows the axial sliding and pivoting of the rolling element relative to the arm. A spring device biasing the two rolling elements away from each other in a direction perpendicular to the axis common to the respective concave cylindrical surface portions of the rolling elements is also provided.
