ABSTRACT:
A universal joint includes two joint yokes that, respectively, have two yoke arms that each start from a connection portion. Through an eye portion distanced from the connection portion, bearing bores extend in which respectively, a journal of a journal cross by means of interposition of rolling members and of a bearing bushing are supported. On the outside of the yoke arms, a bulge is respectively provided towards the connection portion and adjacent to the bearing bore and over a partial circumference of the same, which bulge has, towards the bearing bore, a groove. A circumferential groove, belonging to a retaining trunnion projecting from the base of the bearing bushing, is arranged opposite to the groove. Between the two, a securing element is arranged that engages with an engagement portion in the groove and with a retaining portion facing away from the same, in the circumferential groove of the retaining trunnion. As the groove for receiving the securing element, which serves for the retainment of the bearing bushing in the bearing bore, is not designed to extend circumferentially fully around the bearing bore, the material thickness on the free end of the yoke arms can be reduced on the outside.
