POSITIVE HOLD DIFFERENTIAL ABSTRACT OF THE DISCLOSURE A positive locking differential that functions to compensate for the difference in driving wheel travel which occurs when turning or traveling over uneven ground, while at the same time functioning to prevent wheel-slip when one wheel looses traction. The differential comprises a spider-center cam assembly having four trunnions projecting radially from a center ring on each side of which is located a plurality of fixed driving clutch teeth. The internal diameter of the spider mounts the center cam in such a manner that the same may be rotated a limited, predeter- mined distance. The center cam is symmetric having cam lifts on each side which include rounded surfaces that provide anti-friction ramps for disengaging driven clutch members mounted on each side of the spider and center cam assembly. The driven clutch members have clutch teeth which correspond to the clutch teeth on the spider and through which a driving torque is transmitted. Dis- engaging cams radially inwardly spaced from the driven clutch teeth and rigidly attached to the clutch are adapted to mesh with the cams of the center cam member. Enlarged sections and corresponding slotted portions disposed between the clutch members and the spider-cam assembly at spaced intervals maintain the clutch members in a disengaged mode during relative movement between the clutch members and the spider-cam assembly. Suitable splined members are provided to receive the vehicle axle shafts to transmit the torque from the positive locking differential to the vehicle wheels.
