  • Patent number: 8146458
    Abstract: A locking differential for an automotive vehicle including a housing and a differential mechanism supported in the housing. The differential mechanism includes a pair of clutch members disposed in spaced axial relationship with respect to each other wherein each clutch member includes a groove disposed in an opposed inwardly directing face that is adapted to receive a cross pin. Each of the grooves includes a working surface extending laterally relative to each other. Each of the working surfaces defines a screw involute surface such that the cross pin 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. Alternatively, each of the working surfaces defines a slightly convex surface in one plane such that the cross pin contacts the working surface at a point defined thereon.

  • Patent number: 8117946
    Abstract: A clutch assembly for a locking differential includes driving clutch members engaged with driven clutch members in a preloaded configuration to provide a minimum amount of preload there between during low torque conditions. The driving clutch members are biased relative to each other with shear pin/spring assemblies located within bores of the driving clutch members. During assembly of the clutch assembly, the shear pin/spring assemblies may be positively locked down within the bores with a removable tool. In one embodiment, the removable tool is inserted into a small opening extending through the driving clutch member and the tool engages an annular groove on a shear pin of the shear pin/spring assembly. Further, the clutch assembly may include driving clutch members having drainage openings that may help prevent hydraulic lock during operation of the locking differential.
