Torque distribution controller for four-wheel-drive vehicle

Abstract

Abstract PURPOSE:To facilitate the structure of hydraulic pressure controller for driving the front and rear wheels by varying the hydraulic pressure of one clutch while maintaining the other at setting level thus varying the distribution of driving torque. CONSTITUTION:In a transfer for distributing the output torque of engine to the propeller shafts 6, 7 for driving the front and rear wheels, clutches 34, 35 for driving the front and rear wheels are arranged on the outercircumference at the other end of drive shaft 33 coupled on same axis with that of the output shaft 21 of transmission. Said clutches 34, 35 are controlled by feeding pressure oil through variable flow control valves 43, 44 to respective operational hydraulic chambers 34b, 35b. Respective flow control valve 43, 44 is variably controlled through control unit 47 with correspondence to the outputs from travel condition detecting sensor 48 and torque sensor 49 thus to vary the hydraulic pressure to be applied onto respective hydraulic chamber 34b, 35b and to vary distribution of driving torque.
