Abstract
A tripod joint including an outer joint member with several axially extending elongate tracks; an inner joint member with several radial axle journals distributed over the outer circumference thereof; at least a number of rollers corresponding to the number of axle journals, where the roller is respectively pivotably retained with a central bore on the associated axle journal and is in engagement with the elongate tracks, where the roller is accommodated in the associated track so as to be displaceable in the axial direction of the outer joint member; where each axle journal includes on its circumference two outer diametrically opposed spherical end faces for engagement into the bore, where the bore has a cylindrical portion for engagement with the spherical end faces in order to support the roller so as to be displaceable relative to the journal, and at least a constricted portion that is adjacent thereto in the axial direction, while forming a continuous transition, on one side of the cylindrical portion, and that reaches behind the spherical end faces, for limiting the displacing movement.
