Embodiment Construction

[0018] Embodiments of the present invention will be explained below in conjunction with the accompanying drawings.

[0019] like Figures 1 to 4 As shown, the integrated air brake device for rail vehicles in this embodiment has a brake integrated board 1 and a device and a mounting frame 6 fixed on the integrated air circuit board. The brake integrated board 1 is composed of a front panel and a rear bottom plate. It is made, and the air path is processed on the bottom plate. Both the panel and the base plate are made of aluminum plates, and the two plates are connected by brazing. Brake integrated board 1 is equipped with main valve 2, emergency valve 3, shut-off plug 4, check valve 5 and sensors (pipe pressure sensor, main air pipe pressure sensor, brake cylinder pressure sensor and auxiliary air cylinder pressure sensor) ). Specifically, the pre-embedded steel wire threaded sleeve is used to install the cut-off plug and check valve on the front of the brake integrated pla...

Abstract

The invention relates to an integrated air braking device for rail vehicles, which comprises a brake integrated plate and a main valve, an emergency valve, a stopper valve, a check valve, a column pipe pressure sensor, a main air pipe pressure sensor, a brake cylinder pressure sensor and an auxiliary air cylinder pressure sensor mounted on the brake integrated plate. The brake integrated plate isalso provided with a train pipe interface, a working air cylinder interface, a brake pipe interface, an auxiliary air cylinder interface, a main air pipe interface, a brake cylinder interface and a living air pipe interface, and the brake integrated plate is internally provided with an air path to ensure the communication between each equipment of the air path plate. The device of the invention centralizes the function of the 104 distribution valve, and can brake the vehicle and alleviate the effect; the QD-G function can realize the conversion of single pipe and two pipes of the vehicle, andat the same time provide the wind demand for the auxiliary system of the vehicle; pressure sensors are also installed to detect the pressure in each piping when the vehicle is braked.

Description

technical field [0001] The invention relates to the technical field of air brakes, in particular to an integrated air brake device for railway passenger cars and EMUs. Background technique [0002] At present, high integration has not been achieved in the field of railway passenger cars. The core component of the brake control system 104 distribution valve, the core component of the vehicle air supply system QD-G air circuit control box and monitoring equipment are scattered in different places under the train. Various pipeline connections and pipeline layout are intricate, if a fault occurs, it is difficult to find it; at the same time, it is inconvenient to maintain and overhaul. Contents of the invention [0003] The purpose of the present invention is mainly to solve the above-mentioned problems in the prior art, and to provide an integrated air brake device for rail vehicles, which centrally installs the dispersedly installed brake equipment, so as to reduce the numbe...
