Abstract
In a homokinetic double joint for effecting wide angle bending in the drive transmission line between a drive member and a drive member, such as in the combination of an agricultural tractor and driven agricultural device, a pair of outer yokes are each connected to a double inner yoke by two cross-links. A ball trunnion on each outer yoke is held within a guide member in a centering disc secured in the double inner yoke. Each cross-link has two pair of trunnions, one pair connected into the sides of the outer yoke and the other pair connected into the sides of the double inner yoke. The spacing between the sides of the double inner yoke in which the trunnions are positioned is greater than the spacing between the sides of the outer yokes in which the trunnions are held, thereby permitting wider bending angles between the drive member and the driven member.
