An important part of the normal speed and reliable parking. In order to meet the need of railway transportation, the locomotive braking performance must be put forward certain requirements. For example, can produce large enough braking force; Can easily control the size of the braking force; To coordinate with locomotive other systems; Has the advanced economic technology index, etc. Domestic SS (shaoshan) series electric locomotive to DK - 1 type electric air brake was used as the locomotive brake. Therefore, the requirement for locomotive brake performance, is essentially to DK - 1 air brake performance requirements. DK - 1 type electro pneumatic brake failure is also the main factors affecting its performance, this article introduced our country develop the DK - 1 type of locomotive brake component and function of the DK - 1 type electro pneumatic brake performance parameters, etc and the DK - 1 type brake has carried on the simple introduction, combined with practical experience, detailed introduces the DK - 1 type brake performance test and maintenance. Keywords: Electric locomotive; Brake; The control principle; Performance test; Maintenance; 目 录 摘 要 I Abstract I 第1章 绪 论 1 第一节 概述 DK-1型机车电空制动机主要部件组成及功用 3 第二节DK-1型电空制动机的性能参数 4 第三节 DK-1型电空制动机的控制关系 5 第2章 DK—1型电空制动机故障分析与处理的一般过程 6 第一节 DK-1型自动空气制动机的性能试验 7 第二节DK-1型自动空气制动机日常维护及保养 9 结 论 10 参考文献 11 致 谢 12 绪 论 DK-1制动机电气原理的简统化，维修更方便，提高了制动机性能。 主要部件组成及功用 DK-1型电力机车制动机系统由司机室内的电控制动控制器和空气制动阀等操纵部件以及车体内的空气管路柜中的电空制动屏、分配阀、紧急阀、电动放风阀、空电联合转换装置等组成。主要部
