ABSTRACT:
A tripod joint has an outer joint part with three circumferentially distributed, axis-parallel recesses which form circumferentially opposed tracks. An inner joint part with a star-shaped cross-section and three circumferentially distributed arms engaging the recesses in the outer joint part is associated with the outer part. The arms support roller assemblies. Each roller assembly has at least one inner ring and an outer roller. The inner ring is angularly movable relative to the arm and axially movable relative to the arm axis. A rolling contact bearing is arranged between an outer surface of the inner ring and an inner surface of the outer roller. Also, the outer surface of the outer roller rolls directly on the tracks. The inner ring and outer roller, with reference to the joint axis, are each supported radially outwardly independently of one another. Also, the inner ring and outer roller, with reference to the joint axis, are radially inwardly supported independently of one another directly on a securing element. The securing element, with reference to the joint axis, is radially inwardly supported on guiding edges of the recesses.
