A torque transmitting universal joint of the tripode type, having an outer joint part (13) with three circumferentially spaced recesses (14) extending parallel to its rotational axis and each defining opposed tracks, an inner joint member (11) having arms (12) extending into the recesses, each arm supporting a respective roller assembly (16) with a roller (18), the roller being carried relative to the arm so that it is movable lengthwise of the arm and is able to rotate about and pivot relative to the arm. Each roller is supported on a part-spherical surface of the arm or of the roller-carrying means so arranged that when the joint is transmitting torque in the aligned condition, the resultant of forces acting on the roller through the part-spherical surfaces is at a perpendicular distance from the axis of rotation of the joint different from the perpendicular distance from the axis of rotation of the joint of the resultant of forces acting on the roller from the outer joint member, so that the roller is subject to a tilting moment about its region of contact with the loaded track. <IMAGE> |
