<p>A locking differential (10) including a housing (12) and a differential mechanism (38) including a pair of clutch members (40) that present an inwardly directed face (62). Each face includes a groove (64) disposed in spacing relationship with respect to the other. A cross pin (66) is received in the grooves (64) and is operatively connected for rotation with the housing (12). The clutch members (40) are axially moveable within the housing (12) so that they may engage respective clutch members coupled to a pair of axle half shafts (30, 32). Each of the grooves (64) in the clutch members defines a first predetermined radius of curvature (RG). The cross pin (66) defines a second radius of curvature (RP) wherein the first radius of curvature of the groove (64) is greater than the second radius of curvature of the cross pin (66) such that contact between the cross pin (66) and the groove (64) defines a line extending along the axis of the cross pin (66).</p> |
