Abstract: A brake control device includes: a valve block furnished with valves which regulate or switch air pressure; a controller which electrically controls a plurality of solenoid valves via solenoid valve control signal wires; and an electropneumatic plate which includes solenoid valve connection air channels for the plurality of solenoid valves, and onto which is installed the plurality of solenoid valves so as to communicate with the solenoid valve connection air channels. The plate is secured to the valve block, and at least one of the solenoid valve connection air channels communicates with a support member air channel formed in the valve block.

Abstract: A brake control device includes a relay valve that generates a first drive pressure for driving a brake, from an air pressure generated by a first air supply source, based on an pilot pressure applied, and a double check valve that connects the relay valve and a second air supply source that generates a second drive pressure separate to the first air supply source, and that communicates the drive pressure which is generated in either the relay valve or the second air supply source, with the brake. The device also includes a variable load valve that outputs a first pressure according to a pressure of an air spring fitted on a vehicle side, a first solenoid valve group which generates the pilot pressure from the air pressure during service operation, and a second solenoid valve group which outputs, as the pilot pressure, a second pressure according to the first pressure output from the variable load valve during emergency operation.
