Torque-coupling device for front-wheel-drive transaxle unit

摘要

A front-wheel-drive transaxle unit for a motor vehicle comprises a differential assembly having a differential mechanism disposed in a differential case and two opposite output shafts outwardly extending from the differential case and a torque-coupling device for selectively restricting differential rotation of the differential mechanism. The torque-coupling device includes a friction clutch assembly for selectively frictionally engaging and disengaging the differential case and one of the output shafts, and a selectively controllable clutch actuator assembly for selectively frictionally loading the friction clutch assembly. The clutch assembly includes at least one first member non-rotatably coupled to the differential case and at least one second member non-rotatably coupled to one of said output shafts. The torque-coupling device provides the differential assembly of the front-wheel-drive transaxle unit with both limited-slip and open differential capabilities.
