Abstract
A differential assembly having first structure, which is configured to rotate along a differential axis in response to receipt of a rotational input, a second structure, which is supported for rotation on the differential axis, a third structure which is support for rotation on the differential axis and disposed between the first and second structures and operable in an engaged condition that transmits torque between the first and second structures and a disengaged condition that inhibits torque transmission between the first and second structures, a differential gear set, which is coupled to and rotatably supported within the second structure, and a biasing mechanism, which biases the third structure in the disengaged condition. The third structure is placed in the engaged condition if a torsional magnitude of the rotational input exceeds a rotational force exerted through the differential gear set. A vehicle drive train is also provided.
