Abstract

Embodiments of the present application provide an emergency braking control device, an emergency braking system, and a rail vehicle, which relate to rail vehicle technology and are used to overcome the problem in the related art that it is difficult for multiple carriages to achieve synchronous braking, resulting in braking shock between carriages. question. Among them, the control device includes: emergency brake air circuit assembly and safety loop; emergency brake air circuit assembly includes: solenoid valve, pneumatic valve; the solenoid valve is used for connecting with the main air pipe of the rail vehicle; the solenoid valve and the pneumatic valve connection, the pneumatic valve is used to connect with the air outlet of the rail vehicle; the pneumatic valve is also used to connect with the train pipe; the safety loop includes: the driver emergency brake switch and at least one passenger emergency brake switch in series; the safety loop It is used to control the solenoid valve to connect the main air pipe with the pneumatic valve when it is disconnected, so that the compressed gas in the main air pipe can enter the pneumatic valve through the solenoid valve to drive the pneumatic valve to open, so that the compressed gas in the train pipe can pass through. Pneumatic valve discharge.

Description

technical field [0001] The present application relates to rail vehicle technology, in particular to an emergency braking control device, an emergency braking system and a rail vehicle. Background technique [0002] Indirect-acting air brake is one of the braking methods of rail vehicles; it produces a braking effect when the train pipe pressure of the rail vehicle decreases; it relieves braking when the train pipe pressure rises. [0003] In the related art, a driver's brake handle, a passenger's brake handle and an emergency braking device are provided in the rail vehicle; both the driver's brake handle and the passenger's brake handle are pneumatic valves, and the pneumatic valves are connected to the train pipes through pipelines. When it is necessary to use the passenger emergency brake handle to achieve emergency braking, the train driver needs to notify the crew or passengers of each car to operate the passenger brake handle through the voice intercom system to quickly...
