ABSTRACT:
This device, comprising a housing (10), an input member and two output members (14, 15) as well as a controlled-slip coupling device (23) arranged between two of the said input and output members, is characterized in that the differential comprises at least one member (14) axially movable under the effect of a torque exerted on it, the displacement of this member being utilized to modify the operating characteristics of the controlled-slip coupling.
This provides a differential with a slip self-controlled as a function of the torque and of the speed difference between the output members, the law of variation of which is appreciably improved in relation to that of the known devices.
