The invention relates to railway transport, in particular to the brake control system of automatic brakes of connected trains.

The purpose of the invention is to reduce the time spent on preparation for movement after the train is disconnected from the train:

The drawing shows a schematic diagram of the system

The driver's crane is mounted on the head locomotive of the train with the handle 1o. The cavity A above the surge piston 2. communicates directly with the surge tank 3j with the crane shut off (not shown) and the emergency braking valve A. The stem 5 of the balance piston rests on the overflow valve 6c. with air distributor 8 and cavity B under the equalizing piston, and cavity C under the exhaust valve with pressure line 9

On the locomotive located in

In the middle of the train, a driver's crane is mounted with a handle 10 °. Cavity 1 above equalizing; the piston 1 communicates directly with the surge tank 12, the emergency braking valve 3 and through the open end valve and the intersectional connection (not shown) with the brake line 7 of the train head Stock 14 of the balancing piston 11 abuts the overflow valve 15 The brake 16 is communicated with the air distributor 17 and the cavity D under the equalizing piston, and the cavity E under the valve 15 with the pressure line 18 ,, The air distributor 17 is connected to the brake cylinder 19

The system is controlled by the driver of the first locomotive by the crane of the driver by changing the pressure in cavity A and, accordingly, in the surge tank Zs. When braking, the pressure in cavity A decreases by a predetermined value, the surge piston 2 rises and the compressed air from the brake line 7 runs out through valve 6 atmospheric pressure reduction in line 7 is transferred to the surge tank 12 and the cavity r above the surge piston II of the driver’s crane with the handle 10: the second locomotive, which discharges ormoznoy highway

16 through the valve 15 into the atmosphere. The air distributor 7j, having actuated, fills the brake cylinder 19o with compressed air.

When the brakes are released, the pressure in cavity A and surge tank 3 rises, balancing piston 2 lowers and opens valve 6, informing brake brake 7 with discharge pressure 9o. As a result, pressure increase in brake brake 7 is transferred to balance tank 12 and cavity G equalizing piston 11 of the second locomotive driver crane; The piston 11 is lowered, opens valve 5 and feeds brake line 16 of the second train from pressure line 18

In the proposed system, a direct connection of the cavity above the equalizing piston with the equalizing reservoir; emergency brake valve and brake line of the first train as well as in the well-known one, ensures synchronous operation of the brakes of the first and second train

To cause braking of both trains from the second locomotive, it is necessary to open the emergency valve. braking In this case, the brake. Line 7 of the first train is discharged through the open atmospheric orifice of the valve 13 of emergency braking and at the same time it is recharged through the crane of the driver with the handle 1 of the first locomotive.

The equalization tank 12 and the cavity D above the balancing piston 11 of the second locomotive, controlling the pressure decrease in the brake line 16, are also discharged through the open atmospheric opening of the emergency brake valve 13 and simultaneously fed from the brake line 7 "

Thus, due to the direct communication of the brake line 7 with a surge tank 12, the control cavity G and the emergency braking valve 13, the brake pipelines are discharged simultaneously to the same value by the rate determined by the area of the emergency brake valve. This allows you to reduce the longitudinal dynamic reactions in the train when performing emergency

braking from the second locomotive of a double train.

Continuously connecting the surge tank 12 to the cavity above the piston 11 of the second crane driver reduces the time taken to take the main tracks before the double train disbanding station by reducing the time to prepare the second train for movement after stopping and disconnecting the twin train as the surge tank remains filled with air whose pressure corresponds to the pressure. the air in the brake line is braked (after service braking) of the second train. It is necessary to release the brakes and the train is ready to go.
