Abstract

The invention relates to railway transport. The purpose of the invention is to increase efficiency and efficiency. The pulses coming from sensor 6 to the input of counter 16 are converted into binary code and control the operation of multiplexer 18, the potential of which is supplied to one of the information inputs of the switch 7. in the curved sections of the path, the potential to the input of the multiplexer 18 comes from the sensor 7. With the arrival at the counter 16 of the pulse corresponding to the input number of the multiplexer 18 if there is a input otentsiala selected manually. or by the sensor 7, the potential at the output of the multiplexer 18 changes. This signal triggers the one-shot 19 ° C. The output of the one-shot 19. The signal goes through the amplifier 20 to the winding of the electropneumatic valve. 2 Il. Q

The invention relates to railroad road transport and relates to a device for lubricating wheel flanges of railway rolling stock.

The purpose of the invention is higher efficiency and cost effectiveness.

Figure 1 shows a diagram of a device for lubricating wheel flanges, a rail vehicle; 2 is a schematic diagram of an electronic control unit of a device for lubricating wheel flanges.

The device consists of a reservoir 1 for lubrication, nozzles 2, oil .3 and air 4 pipelines, an electronic control unit 5, a distance sensor 6, a sensor 7 of the trolley angular movements, an electropneumatic valve 8, disconnecting valves 9-11, regulators 12 and 13, a rotary valve 14 and a main air pipeline 15. The distance traveled sensor 6 is made on the basis of a contactless switch and is connected to the locomotive wheel via a speed meter shaft drive. When the locomotive progresses a certain distance, the sensor 6 generates a pulse of rectangular shape.

The angular displacement sensor 7 represents an eight-position proximity switch with a movable element mechanically coupled to a locomotive cart. The control unit 5 contains a binary counter 16 pulses, a switch 17 inputs, connected in parallel to the outputs of the sensor 7 angular displacements, a multiplexer 18, a one-shot 19 and a power amplifier 20

The sensor 6 is connected to the input of the counter 16, the inputs of which are connected to the address inputs of the multiplexer 18. The information inputs of the latter are connected to the outputs of the sensor 7 of angular movements and to the contact switches of the 17 inputs. The output of the multiplexer 18 is connected to a one-shot 19 which is connected via the output to the fault input of the counter 16 and to the input of the power amplifier 20, the output of which ™ is connected to the winding of the electropneumatic valve 8 "

The device works as follows.

way

The pulses coming from the sensor 6 traversed path to the input of the counter 16 and converted last to binary

The code controls the operation of multiplexer 18, to one of whose information inputs the potential is fed from the input switch 17 When the rolling stock moves, the potential to the input of multiplexer 18 comes from the angular displacement sensor 7, converting the angular displacement 10 of the carriage relative to the locomotive body as it moves along curve paths in the positional code.

When a pulse corresponding to the number of the input of the multiplexer 18 arrives at the counter 16, the potential selected manually or by the sensor 7 changes at the input of the multiplexer 18 "This signal triggers the one-shot 19

20 with adjustable delay time, From the output of the one-shot 19 signal goes to the power amplifier 20 and at the same time resets the trigger trigger 16o to the load amplifier

25, an electropneumatic valve B serves to supply air to the nozzles 2, the latter are turned on, and lubrication is supplied to the wheel flanges,

30 Formula of invention
