Abstract

A tripode joint with an outer joint part which comprises three circumferentially distributed axis-parallel recesses forming circumferentially opposed tracks, and an inner joint part whose cross-section is star-shaped and which is provided with three circumferentially distributed arms which engage the recesses of the outer joint part, with the arms supporting roller assemblies each comprising a roller carrier and a roller, which by way of a needle bearing, is rotatably supported on the roller carrier, with the rollers being arranged relative to the respective arms so as to be axially movable relative to the arm axis and angularly movable relative to the arm axis; and with reference to the roller axis (B), there is provided only one mutually effective axial securing element between each roller carrier and the respective roller in the form of only one single securing ring which may be subjected to loads in both directions and which engages radially opposed first and second annular grooves in the inner face in the roller on the one hand and in the outer face of the roller carrier on the other hand.
