Integrated actuator assembly for disconnector device and electronic limited slip differential device

An integrated actuator assembly for a disconnector device and an electronic limited slip differential (eLSD) device, the integrated actuator assembly comprising:

• a driving motor;
• a shift fork configured to slide into a fastened state of the disconnector device in which an outer case and an inner case of the disconnector device are fastened in an axial direction of an output shaft;
• a piston unit including a piston configured to press a multi-plate clutch of the eLSD device in the axial direction of the output shaft so that the eLSD device is in an operation state in which the multi-plate clutch is operated;
• and
• a ball ramp operation unit configured to slide the shift fork and the piston unit to operate in a direction away from each other as rotated by the driving motor;
• wherein the ball ramp operation unit allows the eLSD device to be in the operation state after rotating at a predetermined angle after the disconnector device has been fastened,
• wherein the ball ramp operation unit includes:
• a fixed ramp configured to be rotated by the driving motor;
• a shift guide having a slot having a predetermined profile along a circumference formed within the shift guide, connected to the fixed ramp to change a rotation motion to a linear motion of the fixed ramp, and configured to slide the shift fork;
• wherein an extension extending toward the shift guide is formed on one side surface of the fixed ramp, and a finger including an end portion inserted into the slot is formed on the extension;
• and
• wherein, when the fixed ramp rotates, the finger is configured to slide the shift guide while rotating inside the slot.
