To provide a brake device for a railroad that simplifies the whole brake device.SOLUTION: A brake device for a railroad includes: a brake mechanism 10 that brakes a railroad vehicle by pressing a friction material 11 against a to-be-braked member of a railroad vehicle; an electric motor 20 that drives the brake mechanism 10; an air cylinder 30 that drives the brake mechanism 10; a brake control device 40 that controls a normal brake force by controlling an electric motor 20, based on a pressure of an air spring 60 between a bogie and a vehicle body composing the railroad vehicle, according to a normal brake command; and a solenoid valve 50 that operates an emergency brake by supplying compressed air of the air spring 60 to the air cylinder 30 when an emergency brake command different from the normal brake command is input.SELECTED DRAWING: Figure 2
【課題】ブレーキ装置全体を簡素化する鉄道用ブレーキ装置を提供する。【解決手段】鉄道用ブレーキ装置は、鉄道車両の被制動部材に摩擦材11を押し付けて鉄道車両を制動するブレーキ機構10と、ブレーキ機構10を駆動する電動機20と、ブレーキ機構10を駆動する空気シリンダ30と、常用ブレーキ指令に従って、鉄道車両を構成する台車と車体との間の空気ばね60の圧力に基づいて電動機20を制御して常用ブレーキ力を制御するブレーキ制御装置40と、常用ブレーキ指令と異なる緊急ブレーキ指令が入力されると、空気ばね60の圧縮空気を空気シリンダ30に供給することで緊急ブレーキを作動させる電磁弁50と、を備える。【選択図】図2
