ABSTRACT:
A full time four-wheel-drive system for a vehicle is described which uses a unique torque-transfer case assembly. The transfer case includes a torque input shaft for receiving output torque from the transmission assembly of the vehicle, and front- and rear-output shafts connected to front and rear differentials of the vehicle. The transfer case assembly includes continuously variable belt drive connecting the input shaft to the front and rear output shafts, transferring a predetermined amount of torque to each output shaft. The continuously variable drive arrangement will include at least a primary pulley on the input shaft and a secondary pulley on the front output shaft, the pulleys carrying a belt therebetween. Each pulley comprises a pair of sheaves, which are axially moveable in relation to one another. The pair of sheaves of each pulley are shifted axially relative to one another by an assembly which is responsive to divide torque between the front and rear output shafts in a predetermined relationship. The system operates to substantially maintain this predetermined relationship during normal operation of the vehicle, and balance torque between the front and rear output shafts to yield improved vehicle handling, stability and feel.
