Built-in disconnector assembly for electronic limited slip differential device

An electronic limited slip differential (eLSD) device comprising:

• a disconnector device having a built-in disconnector assembly, the built-in connector assembly comprising:
• a shift guide configured to fasten an outer case of the disconnector device to an inner case of the disconnector device;
• a piston configured to operate a multi-plate clutch;
• a ball ramp operation unit including a driving motor configured to rotate the ball ramp operation unit, wherein the ball ramp operation unit is configured to slide the shift guide and the piston toward the disconnector device;
• wherein the ball ramp operation unit is configured to slide the shift guide to fasten the disconnector device, and to rotate at a predetermined angle to slide the piston to fasten the eLSD device;
• and
• wherein the built-in disconnector assembly further comprises:
• a sleeve configured to be operated by the shift guide;
• and
• a clutch ring formed integrally with the sleeve, wherein a spline is formed along a circumference of the clutch ring, and wherein the clutch ring is configured to rotate integrally with the outer case;
• wherein, when the sleeve and the clutch ring move toward the inner case, the outer case and the inner case are fastened.
