ABSTRACT:
A tripod joint has an outer joint part (1, 41, 61) with three circumferentially distributed longitudinal recesses (2, 42, 62) each forming circumferentially opposed tracks (4, 5; 45, 65). An inner joint part (7, 47, 67) with tripod arms (9, 49, 69) which extend into the longitudinal recess (2, 42, 62) is positioned within the outer joint part (1, 41, 61). Rolling members (10, 50, 70) in rolling contact with the tracks (4, 5; 45, 65) are supported and movably and pivotably held on the tripod arms (9, 49, 69). The longitudinal recesses (2, 42, 62) include guiding means (18, 19) holding the rolling members (10, 50, 70) in the longitudinal recesses (2, 42, 62) so as to be axis-parallel with the joint. The rolling member (10, 50, 70) are in contact with one of the tracks (4, 5,; 45; 65). In each case, there is provided a first contact point (C) for accommodating a circumferentially extending transmission force F.sub.R in the region of a central roller plane (E) and at least one second contact point (A) for accommodating an inwardly directed guiding force F.sub.F in the region of a radially inner supporting shoulder (19).
