The free end of the metering rod is made with a gear rack with the possibility of its movement by the handle of a manual drive by meshing with a gear wheel mounted on a vehicle support.

At the end of the pipeline connected to the nozzle, a conical brush with an internal cavity is fixed so as to enclose the nozzle.

Figure 1 shows a General view of the device; figure 2 - dispenser and valves.

A device for lubricating the rails and wheels of a vehicle, such as a locomotive, car or trolley, contains a tank 1 mounted on the vehicle with a level sensor 2, connected by pipelines 3, 4 and 5 with nozzles 6 and a shut-off valve 7.

The vehicle’s pneumatic line 8 is connected through the electro-pneumatic valves 9 and 10 to the dispenser 11 in the form of a two-chamber cylinder, in the upper chamber 12 of which a spring-loaded piston 13 is mounted, on the rod 14 of which a second piston 16 is put on with the possibility of placing in the lower chamber 15, and in the two holes of the upper the cover 17 of the dispenser 11 is installed inlet 9 and outlet 10 solenoid valves. Moreover, the bottom cover 18 has an opening 19 communicating through the corresponding pipelines 4 and 5 with the nozzle 6. In the case of two-way lubrication of the railway track, two holes 19 are made with two pipelines 4 and 5 and nozzles 6. A gear rack is made on the free end of the rod 14 of the dispenser 11. 20, and on the support 21 of the vehicle mounted with the possibility of engagement with the specified rack 20, the gear wheel 22 with the handle 23.

At the end of the pipeline 5 in the form of a rigid hose, a conical brush 24 with an internal cavity for the passage of lubricant is fixed to cover the corresponding nozzle 6.

Valves 7, 9 and 10 are connected through the control unit 25 and the unit 26 for determining the location of the vehicle to the corresponding servos 27-29. The lubrication system of the device is installed on a vehicle with the ability to control the global navigation system GLONASS.

At the end of the pipeline 4, a safety valve 30 is installed against leakage of liquid lubricant. It can be omitted for lubrication with petroleum jelly or solid oil of various consistencies.

The chambers of the dispenser 11 are separated by a partition having in the central part an airtight hole for the passage of the rod 14.

The device operates as follows. A tank 1 installed on the vehicle with oil and a level 2 sensor, for example, nigrol with more liquid grease, is connected by a pipe 3 to a dispenser 11. Oil enters the dispenser 11 with the shut-off valve 7. open. Oil of a certain viscosity flows by gravity through a large cross-section pipe 3 into the lower chamber 15. After filling it, the shutoff valve 7 is closed. Then, on the vehicle, the inlet electro-pneumatic valve 9 is turned on via a pneumatic line 8. A spring-loaded piston 13 in the upper chamber 12 is moved downward through the first hole with compressed air. At the other end of the rod 14, the second piston 16, which is installed in the lower chamber 15, extrudes oil through the hole 19 in the lower cover 18 in pipeline 4 of smaller section. The sizes of pipelines 3 and 4 are selected in such a way that oil flows out of the first independently, and leaves the second longest under pressure, as from a solid-state pump. At the end, the gravity of the oil is prevented by a safety valve 30 in the form of a ball. Further, under pressure, the oil enters through the pipe 5 to the nozzle 6 and is squeezed out into the hole of the conical brush 24. The bristles of the brush 24 are in contact with the vehicle wheel on one side and with the rail on the other. The wheels of the vehicle are lubricated from its two sides along with the rails.

Thus, the effective lubrication of the rubbing surfaces on the curved sections of the railway.

After extrusion of a certain portion of oil by dispenser 11, valve 9 is closed. The spring-loaded piston 13 returns to its upper initial position, and compressed air is squeezed out through the second hole and the outlet electro-pneumatic valve 10 into the atmosphere. The upper 12 and lower 15 chambers are partitioned off and have a hermetic hole for the passage of the rod 14.

The movement of the rod 14 with the pistons 13 and 16 can be carried out manually. To do this, a gear rack 20 is made on the upper free end of the rod 14. On the support 21 in the vehicle’s room, next to the dispenser 11, a gear wheel 22 is fixed, rotated by the handle 23 to raise and lower the gear rack 20 with the rod 14.

Valves 7, 9 and 10 are turned on and off by servos 27-29, which are controlled by a control unit 25 and a vehicle position determination unit 26 with respect to the beginning and end of the curved section of the railway track. Only in this section is economical lubrication of the rails and wheels of the vehicle to reduce wear of the rubbing pairs. The lubrication system of this device can be automatically controlled by commands sent by the GLONASS global navigation system.

The effectiveness of the device is to save lubricant consumption and allows you to simultaneously lubricate the rails and wheels. In this case, turning on and off the metering drive is done automatically at the command of the global navigation system.
