Abstract

A constant velocity universal joint of the tripode type includes a roller assembly arranged on the tripode arm which is secured against unintentionally disengagement with the tripode arm. A pressure disc is provided which holds the roller assembly together as a unit and whose shape, relative to the ideal round shape, deviates radially inwardly. The radially inwardly directed deviation in shape is designed with a slightly smaller width of opening than the dimension corresponding to the maximum outer diameter of the spherical arm. In this way it is ensured that the roller assembly on the spherical tripode arm is self-holding after having been mounted.
