Abstract

PURPOSE: To enable an engine brake to act on four wheels by simplifying the constitution and by shifting to two wheel driving in such a manner to disengage hydraulic clutch when the difference in driving torques of front and rear wheels exceeds a set value.
CONSTITUTION: Torque signals from a front wheel torque detector 310 and rear wheel torque detector 320 are input to a comparator control circuit 330. The comparator control circuit 330 actuates a solenoid valve 210, to release an oil pressure operating a transfer clutch and to shift the status to two wheel driving, when the difference between the above-mentioned torques exceeds a given value. Thereby, over-load to a transfer device caused by internal wheel difference is prevented even in case of a sharp turn and also effective engine brake operation to four wheel driving at a normal condition can be obtained.
