Claim Text:
1. A limited slip differential assembly for a vehicle, comprising: a differential assembly having a differential mechanism disposed in a differential case and two opposite output shafts outwardly extending from the differential case; a torque coupling unit for selectively restricting rotation between one of the output shafts and the differential case, the torque coupling unit comprising: a friction clutch assembly disposed about one of the output shafts, the friction clutch assembly comprising a first portion drivingly engaged with one of the output shafts and a second portion drivingly engaged with the differential case, a ball and ramp assembly disposed adjacent the friction clutch assembly for selectively frictionally loading the friction clutch assembly, the ball and ramp assembly comprising at least a first portion and a second portion, the second portion rotatable with respect to the first portion, and an actuator in driving engagement with one of the first portion and the second portion of the ball and ramp assembly to selectively cause a rotation therebetween; and a differential housing rotatably supporting the differential assembly and the friction clutch assembly therewithin, the differential housing including a radially inwardly extending portion about one of the output shafts for receiving a ball and ramp assembly support bearing and an output shaft support bearing, wherein the ball and ramp assembly support bearing supports rotation of an actuating ring within the differential housing.
