Tripode joint for increased articulation angles

A tripode joint comprising:

• an outer joint part with a first longitudinal axis (A11) and having an inner recess and three uniformly circumferentially distributed recesses which widen said inner recess and which form pairs of circumferentially opposed tracks;
• a tripode star with a second longitudinal axis (A12) and having a hub and three uniformly circumferentially distributed tripode arms which are arranged radially at said hub and which each form an arm head with a spherical surface portion;
• and
• a roller assembly, on each of the arm heads, each of the roller assemblies being guided in one of the recesses and each roller assembly comprising an annular roller carrier, bearing needles rotating on the roller carrier, a roller which is rotatably supported on the bearing needles,
• wherein the roller carriers, on their inner faces, each comprise a cylindrical arm contact face and, on their outer faces, a cylindrical needle contact face,
• wherein the roller carriers, are arranged on the arm heads so as to be pivotable and displaceable along an arm axis (AZ) and wherein the rollers roll on the tracks with roller axes (AR) which are substantially axis-normal relative to the first longitudinal axis (A11),
• wherein the roller carriers, on their outer faces, each comprise stop collars which delimit the needle contact face, and which are held with an axial displacement clearance (SA) in the direction of the roller axes (AR) between axial securing members to permit translation of the roller carrier during joint articulation along the needle contact face over the axial displacement clearance (SA),
• wherein the roller carriers, on their inner faces, with reference to the first longitudinal axis (A11), at least on the radial inside end, each comprise cylindrical projections which, with reference to the roller axes (AR), increase the axial length of the arm contact faces beyond the extension of the needle contact faces, and
• wherein the axial securing members comprise at least one securing ring which engages an inner annular groove in the rollers.
