AUXILIARY BRAKE VALVE FOR TRACTION ROLLING STOCK Russian patent published in 2024 - IPC B60T15/04 

FIELD: railway.

SUBSTANCE: invention relates to means of remote control of the braking process of traction rolling stock and can be used when performing shunting operations and auxiliary braking on a train. The auxiliary brake valve of traction rolling stock contains an auxiliary brake valve controller installed in the control panel of the traction rolling stock, connected to a control unit, which is equipped with a control program, with which at least one pressure sensor is also connected, electro-pneumatic brake and release valves, a gearbox through which the feed the line is connected to the electro-pneumatic braking valve and the pneumatic braking valve, a compressed air pneumatic distributor having a control pressure cavity connected to at least one pressure sensor, and a cavity for connecting the brake cylinders with the supply line and the atmosphere, a pressure indicator, wherein the control unit is connected to the controller driver's tap, electro-pneumatic auto-stop valve and pressure indicator. The auxiliary brake valve of the traction rolling stock is additionally equipped with a three-way valve with an electric contact, one input of which is connected to the electro-pneumatic braking and release valves, the other input of which is connected to the pneumatic braking and release valves, and the output is connected to the control cavity of the compressed air distributor, and the electrical contact is connected with control unit. The auxiliary brake valve of traction rolling stock provides the ability to control the auxiliary brake from one controller of the auxiliary brake valve in both remote and backup control modes, the ability to set the auxiliary brake valve controller to any pressure value in the brake cylinders, automatically turn on the auxiliary brake during auto-stop braking and emergency braking operator's valve, regardless of the position of the auxiliary brake valve controller.

EFFECT: simplification of control of the auxiliary brake valve.
