Differential device with two-step ability to limit differential motion

A differential device, comprising:

• an input member arranged to receive torque to rotate about an axis;
• a gear set including output gears rotatable about the axis, the gear set being so coupled with the input member as to mediate transmission of the torque from the input member to the output gears while allowing differential motion between the output gears;
• a first clutch so coupled with the input member and one of the output gears as to limit the differential motion;
• a first pressure plate axially adjacent to the first clutch and axially movable to press on the first clutch;
• a first cam mechanism adjacent to a medial member to press the first pressure plate toward the first clutch;
• a second clutch that, when connected, drivingly connects the one of the output gears with the input member;
• a second pressure plate axially adjacent to a ring and a clutch member, the second pressure plate being axially movable to cause first clutch teeth and second clutch teeth of the second clutch to engage with each other;
• and
• a driver disk rotationally movable from a first position via a second position to a third position, the driver disk including a pressing member so coupled with the first cam mechanism as to, from the first position to the second position, rotate the first cam mechanism along with the driver disk and to, from the second position to the third position, allow the first cam mechanism to create rotational difference relative to the pressing member, wherein the driver disk in combination with the second pressure plate forms a part of a second cam mechanism for driving the second clutch.
