Abstract

The invention discloses an electro-pneumatic brake, comprising a main air module, a balanced air cylinder pressure control module, a brake pressure regulating module and a parking brake pressure control module. The equalizing air cylinder pressure control module is provided with an equalizing air cylinder, a first air supply pipeline for supplying air to the equalizing air cylinder is communicatedwith the main air module, a second air supply pipeline for supplying air to the train pipe and a relay valve are communicated with the main air module, and the relay valve controls the air supply andexhaust of the train pipe through the pressure difference between the equalizing air cylinder and the train pipe. The balanced air cylinder pressure control module controls the gradual pressure change of the train pipe or the pressure stage change of the train pipe, thereby realizing the stage adjustment of the locomotive braking force, in accordance with the UIC 540- 2006 Standard Requirements.

Description

technical field [0001] The invention relates to the technical field of locomotives, in particular to an electropneumatic brake. Background technique [0002] For a long time, AAR (Association of North American Railways) and UIC (International Union of Railways) have defined their respective systems as standards, referred to as AAR system and UIC system. At present, the railways in the United States, Canada and Japan use the AAR system, and Western Europe and former European colonies mostly use the UIC system. Due to historical reasons, the railway rolling stock in my country basically uses the AAR system. [0003] The AAR air automatic braking system is mainly a one-off relief type (also called direct relief type) braking system, that is, in the state of train braking, the pressure of the brake pipe is increased to a certain level, which can realize the complete release of the train brake, and the whole The consistency of train relief is good, and it is suitable for long tr...
