ABSTRACT:
A flange driver for a cardan joint with a spider comprised of two pins mutually offset by 90.degree. and two essentially same-design yoke halves. Each yoke half includes a base and a bearing part with a bore contained in it. Both yoke halves abutt along an interface which is essentially perpendicular to the axis of a first spider pin supported by the yoke. Both yoke halves feature a system for torque transmission from the shaft adjoining the joint to the flange driver and to the spider or in reverse order. Both yoke halves of the flange driver are joined to each other positively. Each yoke half features on its interface a toothing directed toward the respective complementary interface. The flank lines of the toothing or a plurality of tangents to the flank lines, projected in a common plane with the yoke axis, extend at an angle greater than 0.degree. to smaller than 180.degree. relative to the yoke axis.
