Description

I

The invention relates to career rail transport, in particular, electropneumatic brakes of the rolling stock.

Automatic electropneumatic brakes are known, comprising a driver valve with a controller, supplying a brake line connected to an air distributor, a pressure relay with a control cavity and electropneumatic braking and discharging valves, including a spare tank with a brake cylinder and a brake cylinder with an atmosphere.

However, the known brakes have low braking efficiency.

The purpose of the invention is to accelerate the filling of the brake cylinders, to increase the brake efficiency and reliability of the actuation of the brake.

To do this, it is equipped with a check valve, mounted between the electropneumatic braking and tempering ventilation valves, and the switching valve M; connected to the outlet channel, to the control of the cavity of the pressure relay, one inlet channel through the additional tank to the air distributor and another inlet channel through the additional tank to the cavity between the check valve and the electropneumatic release valve, and the electric circuits of the brakes and discharge electropneumatic valves of the brakes and discharge valve are connected through a semiconductor valve .:

FIG. 1 shows a diagram of an electro-pneumatic brake installed on a dump truck; in fig. 2 is a brake control circuit whose components are mounted on a locomotive.

Claims (1)

The electro-pneumatic brake contains a brake line 1 connected via an isolating valve 2 to an air distributor 3 connected to a spare reservoir 4, a pressure relay 5, an isolating tap 6, an additional reservoir 7 and a switching valve 8, the brake cylinder 9 is equipped with an alarm 1O. A disconnecting valve 1l, an electropneumatic brake braking 12, a check valve 13, an electropneumatic tapping valve 14, and an additional reservoir 15 are connected to the disconnecting tap 6. A crane driver 16 supplying the brake line 1 combines a controller that is powered by a battery 17 | ez switch 18 i fuse 19, the Controller consists of switches 20. 21 and relay 22, 23. P ne 22 has closing contacts 24 and 25, and relay 23 has closing contact 26. The indicated couplings are included in the working wires 27 and 28. Lamp 29 beeps Ator 10 included in the LP wire. In the train position, the switch 2 of the controller of the driver's crane 16 applies voltage to the coil of relay 22, “contacts 24 and 25 through wires 27 and 28 of the feed voltage to the electropneumatic cables 12 and 14. The valve 12 blocks the channel from BoaajiiiHiCiii reservoir 4 to the control cavity of the relay of lavololi 5, and input 14 tells the control cavity of the role of pressure 5 with the atmosphere of U1 |. In the nepeKpuuia position, the switch 20 closes the coil circuit of the relay 23, opens the coil circuit of the relay 22. The voltage on the working wire 28 is applied through the contact 26, the wire 27 is de-energized and the electro-pneumatic valve 12 is energized from the drive 28. is de-energized and separates the air channel from the atmosphere. When braking, the switch 21 is released, removed the voltage from the coil 23. The contact 26 removes the voltage from the wire 28 and electro-nemtic pentyl 12 coo6j: aeT spare tank 4 with the control cavity of the pressure relay 5 and the brake cylinder 9. The formula of the invention Automatic electropneumatic TopN4O3 for the career railway; 1 S1 / transport, containing a driver's valve with a controller, power supply brake, a magnetograph connected to the air distributor, a pressure relay with a control cavity and electropneumatic braking and tempering valves, which communicate the spare tank with the brake cylinder and the brake cylinder, characterized in that, in order to accelerate the filling of the brake cylinders, increase the braking efficiency and reliability, it is equipped with a check valve mounted between the electro-pneumatic braking valves neither the tempering nor the switching valve connected by the outlet channel to the control cavity of the pressure relay, one inlet channel through the additional reservoir - to the air distributor and the other inlet channel - through the additional reservoir - to the cavity between the non-return valve and the electro-pneumatic release valve, and the electrical circuits of the coils electro-pneumatic braking and tempering valves are connected through a semiconductor valve.
