<p>A locking differential (10) for an automotive vehicle including a housing (12) and a differential mechanism (38) supported in the housing (12). The differential mechanism (38) includes a pair of clutch members (40) disposed in spaced axial relationship with respect to each other wherein each clutch member includes a groove (64) disposed in an opposed inwardly directing face (62) that is adapted to receive a cross pin (66). Each of the grooves (64) includes a working surface (74, 174, 274) extending laterally relative to each other. Each of the working surfaces defines a screw involute surface such that the cross pin (66) contacts the working surface along a line extending in the direction of the cross pin in the event of differential rotation of an axle half shaft relative to the housing.</p> |
