BW 44-40 Transfer Case - Description

DESCRIPTION









The Borg Warner 44-40 transfer case allows torque to be variably applied to the front axle. By allowing variable application of torque between the front and rear axles, this all wheel drive system can be used on dry pavement without the typical torsional windup that will occur with a standard four wheel drive transfer case. The drive system of this transfer case consists of an input shaft and drive sprocket/clutch assembly, and an output shaft and driven sprocket. The drive and driven sprockets are connected by a drive chain. The clutch assembly consists of a pulse width modulated electromagnetic actuator and a multi-disc clutch pack, and allows variable application of torque to the front axle based on traction and driving conditions. The input shaft of the transfer case is connected to the rear propeller shaft, which drives the rear axle. The output shaft of the transfer case is connected to the front propeller shaft, which drives the front axle.
