System Operation
The torque input from the transmission is passed to the transfer case input shaft. The input shaft connected directly to the differential coupling. The differential coupling connects to the housing which splits the torque between the internal gear and the sun gear by the six planetary gears. The internal gear is connected and passes the torque to the rear output flange. The sun gear is connected to the chain drive sprocket and passes the torque to the front output flange via the chain.
The center differential responds to the torque changes at the axles. The basic torque distribution between the front and rear axles is 40/60% at normal drive conditions. If an axle loses traction, the driving torque is redirected instantaneously to the other axle between 65/35% Front/Rear and 20/80% Front/Rear.
