ABSTRACT:
A ferrous metal yoke for a universal joint, the yoke having a central axis, an annular hub and spaced-apart arms extending from an end of the hub on opposite sides of the central axis. The arms have coaxial openings extending therethrough for pivotably receiving the opposed arms of a first pair of arms of a cruciform-shaped journal cross, and each of the arms of the yoke is provided with a shear center which is positioned between such arm and the central axis of the yoke to provide corresponding or closely corresponding free deflection characteristics under torsional load around the central axis between the arms of the yoke and the arms of the journal cross which are received therein. Such shear center characteristics are obtained by constructing each arm of the yoke with a portion between the end of the hub and the opening in such arm in the shape of an outwardly facing "C" in transverse cross-section, with a generally planar web portion and spaced-apart flange portions extending perpendicularly outwardly from the web portion and generally parallel to each other.
