Abstract

PURPOSE:To attain automatic changeover for front and rear wheel driving operations, in the automatic changeover device of a four-wheel driven vehicle, by obtaining a difference of rotary speed in front and rear wheels and controlling engagement and disengagement operation of a clutch switching the front-wheel and four-wheel driving in accordance with said difference. CONSTITUTION:When front wheel driving operation is basically performed and four wheel driving operation is performed as necessary by an engine 1 equipped to the front in a four wheel driven vehicle, in which front wheels 2, 3 and rear wheels 4, 5 are coupled through a clutch 17 provided in the half way of a driving shaft 16, the clutch 17 is controlled by a controller 15. Outputs of front and rear wheel rotary speed sensors 6 and 7 are input to said controller 15, when a difference between front and rear wheel speeds exceeds a preset value, a working signal 10 is output from a microcomputer 14 through an interface 13. This working signal 10 operates a solenoid 12 to engage the clutch 17, then the vehicle is driven by four wheels.
