INTEGRATED ACTIVE LIMITED SLIP DIFFERENTIAL

摘要

A limited slip differential system having a differential housing, a differential case disposed within the differential housing and a differential gear set supported within the differential case. A friction clutch assembly including a clutch pack is positioned within the differential case and axially adjacent the differential gear set. A ball and ramp assembly is positioned outside the differential case and includes a reaction member positioned within and fixed to the differential housing. A differential bearing is positioned axially between the reaction member and the differential housing and radially outward from the differential case. A singular thrust bearing is located within the differential housing and outside the differential case and applies an axial load from the actuator assembly to the clutch pack.

1. A limited slip differential system, comprising:
a differential housing; a differential case that rotates within the differential housing; a differential gear set supported within the differential case and connected to two axle half shafts; a friction clutch assembly including a clutch pack positioned within the differential case and axially adjacent the differential gear set; a ball and ramp assembly positioned outside the differential case comprising a reaction member, an actuating ring, and a plurality of balls positioned between the reaction member and actuating ring, wherein the reaction member is positioned within and fixed to the differential housing; a differential bearing positioned axially between the reaction member and the differential housing and radially outward from the differential case, wherein the differential bearing comprises an inner race, a roller and an outer race; a thrust bearing located within the differential housing and outside the differential case axially adjacent the actuating ring; and a thrust member in direct contact with the thrust bearing, wherein at least a portion of the thrust member extends through the differential case and axially abuts the clutch pack.
