A universal joint includes a first joint yoke and a second joint yoke having respective base portions. Each of the joint yokes has two yoke arms that are attached on the respective base portions. Each of the yoke arms ends in a free end and has an inner face facing toward the longitudinal axis and an outer face facing away from the inner face. Each of the yoke arms has a bearing bore extending between the outer face and the inner face. The inner face of each of the yoke arms has a first recess that is open toward the free end and that ends in the corresponding bearing bore. A journal cross assembly includes a journal cross having four circular cylindrical trunnions arranged at right angles toward each other, each trunnion supporting a bearing bushing having a cylindrical envelope face and a cylindrical bore. The bearing bushings are supported on the trunnions by rolling members. The envelope face, in the area of the first recess, has a first support-free portion and, diametrically to the first support-free portion, a second support-free portion that is provided between the bearing bushing and the corresponding bearing bore.

Universal joint

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.
