PURPOSE:To permit the smooth turning and smooth traveling on road surface by comparing the signals sent from front wheel speed detectors and operating a differential lock mechanism when the difference becomes over a certain value, thus controlling a car into the differential lock state. CONSTITUTION:A differential lock mechanism 23 is installed onto a front wheel driving shaft 21b by use of a wedge and can be transferred in the axial direction. On the inner edge surface of the differential lock mechanism, a differential lock member 24 having a hook 24a which can be engaged with an engaging hook 22a formed onto the boss of a ring gear 22 can be operated by a solenoid 25. Front wheel revolution detectors 27a and 27b detect each number of revolution of the right and left front wheels 7 and 7 and transmits a signal. When each potential sent from the detector 27a to a comparator 30 differs largely and this potential difference increases larger than the potential difference sent from a standard voltage generator 31, a signal is transmitted into a controller 33, and said signal is amplified by an amplifying circuit 32, and then, the solenoid 25 of the control part 33 is energized to operate the differential lock mechanism 23. |
