Abstract
A joint yoke for a universal joint, as well as to a universal joint having the same. In such a universal joint, the two joke arms in the joint yoke are separated into a base portion having integrally arm portions and bridge elements. For attaching the bridge elements, headed screws are used, for which in the end faces of the arm portions threaded bores are arranged. The threaded bore which, when projected onto the bore axis of the neighboring support bore, has the largest distance from the longitudinal axis has a diameter remarkably increased compared to the other threaded bores . Compared to embodiments in which several headed screws and corresponding threaded bores are provided, which have the same diameter, an above proportional increase of the torque transmission can be achieved.
