ABSTRACT:
A differential control unit for a 4-wheel drive vehicle is disposed between a transmission and a propeller shaft, controls a violator of the speed regulations between front and rear wheels generated when turning the 4-wheel drive vehicle, and limits the torsion stress by its violator of the speed regulations so that it can improve driving performance and keep the vehicle stable. The differential control unit for limiting a differential includes a screw shaft for connecting to the transfer case and transmitting a turning effect, a piston for moving forward and backward relative to the shaft portion, a multiple disc clutch for differential control according to the existence and non-existence of friction created by the forward and backward motion of the piston, a spline gear forming the spline gear on the outer circumference to pass through the inner circumference of the multiple disc clutch, and a housing connected and fixed to the propeller shaft to equip components of a third stopper disposed for supporting the spline gear.
