Description
Technical field
The present invention relates to track train brakes field, particularly relate to brake system of electric locomotive one train tube pressure
Control module.
Background technology
Track train is in traffic design and operation management, and train braking problem is always asking of extremely important and complexity
Topic.Train is in running, in order to ensure safety, will consider various emergency case to greatest extent and take to arrange accordingly
Execute.At present, track train mode of braking mainly has directly braking and indirectly brakes two kinds of major ways, and so-called directly braking is i.e. made
Dynamic electronic control module directly controls EP switching valve by logic thus controls to brake the increasing of the signal cavity volume pressure of relay valve
Subtracting, booster brake, decompression are alleviated, and export big flow constriction air by relay valve and enter brake, reach the mesh braked rapidly
, this type of braking is typically used in the brakes such as train of high-speed motor train unit, subway, magnetic suspension.
So-called braking indirectly, is the size being controlled Brake pipe pressure by an i.e. train pipe of intermediary's pipeline, train pipe
Supercharging, train alleviation, train pipe reduces pressure, train braking, and in order to reach braking and the purpose alleviated, EBCM Electronic Brake Control Module leads to
Crossing logic control equalizing reservoir EP valve module and fill wind and air draft to train pipe, train pipe fills wind supercharging makes brake pipe decompression alleviate,
Train is alleviated, and train pipe air draft decompression makes brake pipe booster brake, and this type of braking is typically used for the brakes such as power train
In.
Owing to train pipe is a long pipeline running through whole vehicle, its supercharging decompression causes alleviation and the braking of train,
So the supercharging decompression time of train pipe is directly connected to the response time of train braking system.Traditional train pipe control module
