両の非常ブレーキ装置。[Scope of Claim for Utility Model Registration] (1) The brake pipe that runs through the vehicle, the source air reservoir tube that is connected to the source air reservoir that stores the pressure air that is the source of braking force, and the a brake valve that discharges pressurized air in the brake pipe and sends a predetermined electrical signal to an emergency discharge command line; an emergency electromagnetic discharge valve that discharges pressurized air in the pipe; an emergency valve that operates when a predetermined pressure drop occurs in the brake pipe; and an emergency restriction valve that limits the pressure value of the pressure air output from the emergency valve. , a variable load valve that changes the pressure air output from the emergency restriction valve according to the occupancy rate, and a relay valve that amplifies the capacity of the pressure air output from the variable load valve and supplies it to the brake cylinder. In the emergency braking system for a pneumatic command vehicle, a second double check valve is provided between the variable load valve and the relay valve, and an output port of the second double check valve is connected to the relay valve. At the same time, one input port is connected to the variable load valve, and the other input port is connected to the source air reservoir pipe via a communication path, and an emergency discharge command line is sent from the brake valve to the communication path. An emergency braking device for a pneumatic command vehicle, comprising a solenoid valve that opens and closes based on an electric signal and a pressure regulating valve. (2) The emergency brake system for a pneumatic command vehicle according to claim 1, characterized in that a second variable load valve is provided in place of the pressure regulating valve.
