Abstract
A die formed monolithic yoke assembly for a universal joint of an automotive driveline assembly subject to high torsional loads having a substantially uniformed thickness, including a cup-shaped portion, a pair of opposed lugs integral with and extending from an upper portion of the cup-shaped portion and an integral, outwardly deformed substantially continuous lip portion extending outwardly from the upper surface of the annular wall and the lugs substantially strengthening the yoke assembly particularly against torsional loads. In one embodiment, the upper end of the cup-shaped portion included concave arcuate portions on opposed sides of the lugs adjacent the lugs, such that the upper surface of the cup-shaped portion transitions from a concave surface to a convex surface strengthening the yoke.
