PURPOSE: A differential lock automatic releasing device prevents the damage of a rear side power transmission device and the abnormal abrasion of a tire by automatically releasing a differential lock of a vehicle on moving beyond a predetermined velocity. CONSTITUTION: A differential lock automatic releasing device comprises an electricity switching device and a vehicle speed perceiving device. The electricity switching device disposed between a differential lock switch(9) and a pneumatic solenoid valve(7) interrupts electric signals inputted into the pneumatic solenoid valve(7) according to a vehicle speed. The differential lock switch(9) and the pneumatic solenoid valve(7) are electrically connected. The vehicle speed perceiving device mounted on one side of a propelling shaft(12) for transmitting a rotating power from a transmission(11) to a differential sends the signal of the vehicle speed to the electricity switching device. |
