TRIPOD JOINT HAVING LOW VIBRATION INDUCING FORCES

摘要

The invention relates to a tripod joint (1), comprising an outer joint element (2) having several axially extending elongate tracks (4) formed therein and distributed over the internal periphery thereof, an inner joint element (3) having several radial journals (5) distributed over the external periphery thereof, at least a number of rollers (6) corresponding to the number of journals (5), wherein each roller (6) is pivotably retained by a central bore (20) on the associated journal (5) and engages with the elongate track (4), wherein the roller (6) is movable in the associated track (4) in the axial direction of the outer joint element (2), wherein each journal (5) has two outer, diametrically opposed spherical end faces (16) in the circumference thereof for engagement in the bore (20). The articulation joint is characterized in that the bore (20) has a cylindrical section (9c) for engagement with the spherical end faces (16) in order to mount the roller (6) such as to be displaceable relative to the journal (5), and at least one constricted section (9d, 9e) which adjoins the cylindrical section (9c) in the axial direction, forming a continuous transition on one side of the cylindrical section (9c), and engages behind the spherical end faces in order to limit the displacement movement.
