Abstract
A transmission assembly includes a cavity in a female U-joint having a groove that extends radially outward from an inner diameter thereof and bounded by three planar drive surfaces. A male U-joint member includes a drive end includes a longitudinal rectangular extension protruding radially outward from a periphery and positioned within the groove of the cavity. The drive end includes a longitudinal rectangular insert has a portion forming the extension positioned within the groove and retained within the drive end. The extension includes (1) opposing longitudinal sides, each forming a side crest disposed between a pair of angular side surfaces that extend axially from the side crest inward toward a center of the extension, and (2) a top side forming a top crest disposed between a pair of angular top surfaces that extend axially from the top crest downward toward the center of the extension.
