Description

I.

The invention relates to railway transport, in particular, to brake systems of multi-section traction vehicles of railway rolling stock, and can be used on locomotives with any number of sections.

The purpose of the invention is to increase the reliability of the braking system of a multi-section rail vehicle.

, The drawing shows a schematic diagram of the brake system of one of the sections of a multi-section railway vehicle, for example, the driven section of a two-section locomotive.

The brake system contains a compressor 1, a main tank.2, a driver’s crane 3, an auxiliary brake valve 4, a feed 5, a brake 6, auxiliary 7 brake lines, as well as additional lines 8 and 9, an air distributor 10 with a spare tank 1 and brake cylinders 12. Highways 6 and 7 are connected to similar highways of the articulated section (not shown) through end valves. 13 and connecting sleeves 14, Between supply line 5 and its connecting sleeve 14 a locking device 15 is installed, equipped with an additional piston 16 mounted on the valve stem 17, Piston 16 separates cavities a and. | . The cavity a is connected to the supply line 5 through a three-way valve 18. In the cavity (5 there is a valve stem 17 and a test hole c is made, which continuously connects this cavity to the atmosphere, in addition, this cavity is communicated by line 9 through the gearbox 19 and switching valve 20 with brake cylinders 12. Valve 17 has saddles d and s. Saddle d crosses the feed line 5, and ce, the column & is a cavity communicating with the atmosphere, and piston 16 has a flat; but less saddle area.

Brake system works as follows.

When charging the brake CHCTei i of multi-sectional traction means, the compressed air from the operating compressor 1 enters the main reservoir 2

and further along the supply line 5, through the locking device 15 and the connecting sleeve 14 - into the feeding line of the articulated section, Cla- 5 pan 17 and piston 16 of the locking device 15 under the action of air pressure of the feeding line 5 and the additional line 8 is in its extreme upper position (cm, draw 10). This is achieved due to the fact that with the same pressure of compressed air in the feed 5 and an additional 8 main lines, the saddle area e is larger than the plunger 16 of the piston 16,

15 When braking by the auxiliary brake crane 4 or automatic braking of the brake line 6 discharge by means of the crane 3 of the driver, the control pneumatic signal from the reserve tank 11 through the air distributor 10 to the inter piston cavity of the crane 4 is supplied.

.25 auxiliary brake through line 7, through switching valve 20, is supplied to brake cylinders 12, In the case of self-disengaging of sections and breakage of connecting hoses, pressure

30 in the cavity f is de- creased, and the piston 16 under the action of the pressure differential of the valve in the cavity f - f moves downwards, with the result that the valve 17 with its seat d. overlaps

35 feeding line 5, wherein knob 21 moves to the closed position, and lines B and 9 are connected; Air from feed line 5 through line: 8 and 9, gear 40, switch switch 20 enters brake cylinders 12. Equalization of pressure in feed line 5 at the connection point and end valve 15 with pressure in O bulk does not cause depressurization . Nutritional line, since the working area of the saddle d is less than the area of the piston 16,

To bring sections of locomotive

50 in working condition it is necessary to close the end valves, 13, and the three-way valve 18 to communicate with the atmosphere a cavity A, After connecting the air hoses 1x articulated lines

J5 sections, the end valves 13 and the locking device 1 5 are opened, and the three-way valve 18 communicates the cavity L through the main line 8 with the supply line 5,
