。[Claims for Utility Model Registration] (1) A first solenoid valve is connected to a first brake system that supplies air pressure from an air tank to the brakes of a semitrailer via a control valve that responds to depression of a foot brake pedal, and A second brake system that supplies air pressure according to the overload of the semitrailer is connected in parallel to the first brake system, and when exhaust braking is performed, the first solenoid valve is closed to disable the first brake system, and the first brake system is inactivated. A control means is provided for operating a second brake system and opening the first electromagnetic valve when the foot brake pedal is depressed to operate the first brake system and disable the second brake system. A semi-trailer brake device characterized by: (2) The 2nd brake system is a decompression valve that reduces air pressure from the air tank according to the excess of the semi -trailer, the second electromagnetic valve that is opened during exhaust brakes, and the foot brake pedal. 2. The semi-trailer brake device according to claim 1, wherein the semi-trailer brake device is configured in a series circuit with a third solenoid valve that is closed at certain times. (3) The control means includes a switch that responds to the foot brake pedal and closes the third electromagnetic valve when the foot brake pedal is depressed, and a switch that closes the third electromagnetic valve when the switch is closed. Utility model registration claim 1, characterized in that it is equipped with a relay that opens the valve and closes the valve when the valve is opened.
A brake device for a semitrailer according to item 1 or 2.
