レーラのブレーキ装置。A first solenoid valve that controls the opening and closing of the exhaust brake valve, a second solenoid valve that controls the operation of the trailer brake, and a pressure fluid for the trailer brake operation supplied to the second solenoid valve provided inside the tractor. a trailer brake control valve for discharging the vehicle, a first switch device that opens and closes in conjunction with the operation of the trailer brake control valve, a second switch device that detects the engine brake running state of the tractor, and a second switch device that detects whether or not the trailer is connected. and a third switch device for detecting, when the tractor is in an engine brake running state and a trailer is connected, the first to third switch devices are activated by operating the trailer brake control valve. When the tractor is closed, the first and second solenoid valves are simultaneously energized to operate the exhaust brake valve and the trailer brake, and when the tractor is traveling alone, by operating the trailer brake control valve in the engine braking state, the first and second solenoid valves are activated. The second switch device is closed and the first
A brake device for a tractor/trailer, characterized in that a solenoid valve is energized to operate an exhaust brake valve.
