Problems solved by technology

[0003] In the above-mentioned conventional brake control device, since the relay valve and the emergency load-adapting automatic adjustment valve are arranged separately as different structural parts, the piping connection between them becomes complicated. In addition, Since there are also solenoid valves, control panels, etc., the number of parts is also large, so naturally there is a problem that a large installation space is required.
In addition, as in Patent Document 1 figure 2 As shown, when a control panel is arranged in the open space above the solenoid valve inside the waterproof cover, there is a disadvantage that the control panel on the upper side is easily affected by heat radiation from the solenoid valve.

Abstract

PROBLEM TO BE SOLVED: To realize miniaturization and to constitute a control panel so as to hardly receive influence of heat release from a solenoid valve.

SOLUTION: The brake control device is provided with a regular use solenoid valve 3 in common use for feeding a control pressure according to an electric signal; a relay valve 10 for feeding a brake pressure to a brake cylinder based on the control pressure; a variable load valve 20 for feeding an emergency control pressure based on the variable load signal pressure from an air spring 7; an emergency solenoid valve 4 for feeding the emergency control pressure to the relay valve 10 according to the electric signal; and the control panel 5 for controlling a voltage applied to the regular use solenoid valve 3 and the emergency solenoid valve 4. The device has a valve body unit 2 installed with the relay valve 10, the variable load valve 20 and the input/output conduit in the inside. The regular use solenoid valve 3 and the emergency solenoid valve 4 are provided on an upper surface side on the outer side of the valve body unit 2 and the control board 5 is provided on a side surface side of the outer side of the valve body unit 2.

Description

technical field [0001] The present invention relates to a brake control device for driving and controlling a brake cylinder provided corresponding to a wheel or the like of a railway vehicle in accordance with the operation of a brake operation unit. Background technique [0002] At present, in the brake control device of railway vehicles, as a common brake system, there is a control panel that outputs a brake command signal (electrical signal), and a brake command pressure corresponding to the brake command signal (electrical signal) is provided. (Air pressure) output solenoid valve, the brake command pressure output by the solenoid valve is used as the control pressure, and the capacity is expanded based on the control pressure and output to the relay valve of the brake cylinder. In addition, it is used as an emergency brake The system has a load-adaptive automatic adjustment valve that expands its capacity according to the total weight of the vehicle including the passeng...
