Abstract

Use: railway transport. SUMMARY OF THE INVENTION: In a curved section of the path, the supply of sand to the outer rail is stopped, and lubricant is supplied to both rails.

Description

The invention relates to railway transport with a predominant use of the railway network in a locomotive.

Methods are known for applying lubricant to the ridges of the wheelsets of locomotives and the lateral inner edges of the head of the outer rail lines in curved sections of the railway track. Liquid, consistent or solid lubricants are applied to the working surface of the wheel flange in contact with the side face of the rail head with continuously automatically operating devices - comb lubricators when the locomotive or other rolling stock moves along a curved section of the track. Stationary devices are also used to apply lubricant to the crests of rolling stock wheels installed on a railway track — track rail lubricators operating on grease or liquid lubricants. When the traveling rail lubricator is operating, the wheel flanges take the lubricant portions from the special plate of the device and spread it along the entire length of the outer rail thread with simultaneous lubrication of the flanges of each wheel.

Lubrication of the side faces of rail heads can also be carried out from locomotives or other types of rolling stock by contact and non-contact.

in a way. When lubricating the wheel flanges and side edges of the rails, their wear is reduced and the resistance to movement of the train is reduced. Sand is fed to the rails to increase the coefficient of adhesion of the wheels of the rolling stock to the rails and to prevent the wheels from the locomotive sandbox from being boxed. In the presence of grease sand, stuck to the contacting surfaces, causes an increase in the intensity of wear of both the rail and the wheel. Depending on the driving conditions, the need to apply lubricant or sand in a number of cases is manifested differently. In this connection, various technical solutions are used to minimize wheel blocking, as well as to reduce the frictional forces between the wheel flanges and the rail head,

A device for sanding or lubricating the rails is known, which is a mechanism that automatically turns the lubricant or sand on and off into the contact zone with the rail head. The principle of operation of the mechanism of the basis on the use of the action of the difference in the speeds of rotation of the axes of the wheel pair and the drive wheel pairs. When braking or counter-spinning, the rotation of the drive wheel pair is slowed down and the mechanical system of the device allows the lubricant to access the rails. In the case of boxing shoi

the rotational speed of the drive axle increases and the flow of sand to the rails opens.

The disadvantage of this device is the simultaneous supply of sand under the wheels moving along the outer and inner threads in the curved section of the track, and therefore their wear increases when there is lubrication on the surface of the wheel flanges and the lateral face of the rail heads. The use of such a device on locomotives that do not have runner axles is impossible.

The purpose of the invention is to completely eliminate the possibility of supplying sand from the locomotive sandboxes to the greased contact surfaces of the wheel flange with the lateral face and the rolling surface of the head of the outer rail thread in the curved track section.

The goal is achieved by ensuring that the supply of sand to the outdoor

When the locomotive moves along a curved section of the track, it is also possible to use this technical solution on any type of locomotive with or without wheel runner pairs.

As a result of using this method, the lateral wear of the rails and wear of the wheel flanges of wheel pairs and, accordingly, the extension of their service life are achieved.
