Abstract

An all wheel drive system for a motor vehicle comprising a front differential, a pair of front halfshaft assemblies operatively connected to the front differential whereby the front differential supplies torque to the pair of front half shaft assemblies, each of the pair of front half shaft assemblies connected to a respective front wheel, a power takeoff unit operatively connected to the front differential, a constant velocity joint connected to the power takeoff unit whereby the front differential supplies torque to the constant velocity joint through the power takeoff unit, a first propshaft having a first end and a second end, the first end connected to the constant velocity joint, a plunging constant velocity joint connected to the second end of the first propshaft, a second propshaft having a first end and a second end, the first end connected to the plunging constant velocity joint, a universal joint having a first end and a second end, the first end of the universal joint connected to the second end of the second propshaft, a self contained speed sensing torque transfer device connected to the second end of the universal joint such that torque is selectively transferable wh…
