More Information
Summary:A universal joint for vehicle drivetrains and the like that eliminates the spinning of bearing caps relative to yoke years and trunnions and inhibits inadvertent spreading of opposing ears of a yoke away from each other under increasing torsional loads to reduce wear and failure of the joint. Broadly, the disclosed universal joint includes a central body having a plurality of pairs of opposite apertures, first and second yokes that are disposed about the central body over respective ones of the pairs of apertures, and a plurality of trunnions inserted through the yoke ears and into the apertures of the body to pivotally secure the yokes to the body. Each trunnion is non-rotatable relative to its respective yoke and a locking assembly inhibits movement of each opposite pair of trunnions away from each other thereby inhibiting movement of the opposite ears of each respective yoke away from each other.
