Abstract

An all-wheel drive system for a vehicle having an engine and a drive shaft is arranged between the drive shaft and front and rear propellable shafts. These shafts are interconnected by first and second clutches respectively, and the propellable shafts are coupled to front and rear wheels, for transferring torque from the drive shaft to the front and/or rear wheels. The all-wheel drive system further includes at least first and second actuators that are coupled to at least first and second clutches, where at least the first clutch is engaged by a spring and at least the first actuator is coupled for disengaging the first clutch when the first actuator is operated. The second actuator is coupled for engaging the second clutch when the second actuator is operated.
