Abstract

A brake control device whose purpose is to achieve miniaturization and to make a control panel less affected by heat dissipation from a solenoid valve. The brake control device has a common solenoid valve (3) that supplies control pressure based on an electrical signal, a relay valve (10) that sends brake pressure to the brake cylinder based on the above-mentioned control pressure, and an adaptation valve based on the air spring (7). The load-adaptive automatic adjustment valve (20) that automatically adjusts the signal pressure to supply emergency braking pressure, the emergency solenoid valve (4) that supplies the emergency control pressure to the relay valve (10) based on the electrical signal, and the A control panel (5) for controlling the voltage on the solenoid valve (3) and the emergency solenoid valve (4), which has a relay valve (10), an automatic load-adaptive adjustment valve (20) and their internal components. The valve main unit (2) of the input and output pipeline is provided with a regular solenoid valve (3) and an emergency solenoid valve (4) on the upper side outside the valve main unit (2). A control panel (5) is provided on the side.

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...
