Title:
DIFFERENTIAL DEVICE CAPABLE OF LIMITING DIFFERENTIAL MOTION IN TWO STAGES
Document Type and Number:
WIPO Patent Application WO/2019/111294
Kind Code:
A1
Abstract:
This differential device is provided with: a gear set which is provided with an input member and an output gear, and which mediates the transmission of torque while permitting differential motion; a first clutch which limits the differential motion; a first pressure plate which is adjacent to the first clutch in an axial direction and is capable of moving in the axial direction to press the first clutch; a first cam mechanism which is adjacent to the first pressure plate to press the first pressure plate toward the first clutch; a second clutch which prohibits the differential motion when engaged; a second pressure plate which is adjacent to the second clutch in the axial direction and is capable of moving in the axial direction to cause the second clutch to engage; and a driver disk which is capable of moving in rotation from a first position, via a second position, to a third position, constitutes a second cam mechanism that, in combination with the second pressure plate, causes the second clutch to engage, and is provided with a pressing member that is coupled to the first cam mechanism in such a way as to cause the first cam mechanism to rotate together therewith from the first position to the second position, and to permit a rotational difference in the first cam mechanism from the second position to the third position.
