Description

The invention relates to railway transport, in particular to a device for lubricating the flanges of wheel sets, lateral surfaces of rail heads and turnout elements for vehicles, such as shunting locomotives, railcars, railcars.

A device for lubricating the flanges of a rail vehicle’s wheel pairs contains a lubricated reservoir, an oil pipe installed with an inclination from the reservoir to the lubricating element, and a lubricating element in the form of a piece of rubber pipe with a core made of solid lubricant (graphite, molybdenum disulfide) located inside the pipe. The rod of the lubricating element is spring-loaded to the lubricated wheel flange, its base is pivotally mounted with the possibility of rotation in the plane of rotation of the wheel around an axis parallel to the axis of the wheel pair, and coaxially with the spring-loaded relative to the glass and installed with the possibility of longitudinal movement of the fitting of the oil supply pipe , with the possibility of opening and closing the oil pipeline, respectively, when rotating and stopping the wheel of the vehicle.

The technical result when using a device for lubricating the flanges of a wheel pair of a rail vehicle is economy, self-regulation of the lubricant supply, autonomy of control and the prevention of oil leakage on the wheel surface while the vehicle is stationary.

A device for lubricating wheel flanges of a railway vehicle is known, comprising nozzles connected by a pipeline to an oil tank, a pulse sensor interacting with a vehicle wheel through a control device connected to an electro-pneumatic valve pneumatically connected to the nozzles, the pulse sensor including an inductor, interacting with a permanent magnet mounted on the wheel, and the control device consists of a stabilizer, multivibrator, force trolley, and the stabilizer inputs are connected to the winding of the inductor, its outputs are connected to the inputs of the multivibrator, the outputs of which are connected through the amplifier to the winding of the electro-pneumatic valve (USSR author's certificate N 1350070. A device for lubricating wheel flanges of a railway vehicle, from 24.03.86, published 07.11.11 .87).

A disadvantage of the known device is the design complexity and the associated lack of reliability and accuracy of lubricant supply to the wheel flange, as well as the high cost of the device.

Also known is a device for lubricating the flanges of a rail vehicle vehicle, selected as a prototype, comprising a lubricated reservoir, an oil pipe mounted with an inclination from the lubricated reservoir to a lubricating element and provided with a locking and adjustment device, and a lubricating element in the form of a piece of rubber pipe, filled with solid lubricant (rod of graphite, molybdenum disulfide) (RF patent for the invention No. 2168434. A device for lubricating the flanges of a wheel pair of a rail vehicle, having a diesel engine dated 12/07/1999, published on 06/10/2001).

The disadvantage of the prototype is the inconvenience of the process of turning the device on and off at the moment of starting and stopping the vehicle, since the shut-off and adjusting device of the oil pipeline is a manual valve. Frequent opening and closing of a crane during numerous stops-pulling off of a vehicle (especially a shunting locomotive, railcar, railcar) leads to increased laboriousness and distraction from the driver’s work or the need for a special operator to be present on the vehicle. Due to the presence of the human factor, there is a high probability of untimely switching on and off the supply of lubricant to the wheel flange during parking, which in the latter case leads to undesirable leakage of lubricant to the tread surface of the vehicle wheel, and from it to the tread surface of the rail.

The challenge facing the creator of the invention is the autonomy of control of the lubricant supply at the moment of starting and stopping the vehicle with the possibility of self-regulation of lubricant supply during operation of the device depending on the presence of lubricant on the wheel flange.

A device is proposed for lubricating the flanges of a rail vehicle’s wheel pairs, comprising a lubricant reservoir, an oil pipe installed with an inclination from the lubricant reservoir to a lubricating element and a lubricating element in the form of a piece of rubber pipe with a solid lubricant rod (graphite, molybdenum disulfide) located inside the pipe ), which is new in that the rod of the lubricating element is spring-loaded to the lubricated flange of the wheel, and the base of the rod is located in a glass that has hinges but rotatably in the wheel around an axis parallel to the plane of rotation of the wheelset and coaxially with the spring on the glass and mounted for longitudinal movement of the feed oil pipe fitting, with the opening and closing of the oil conduit respectively during the rotation and stopping of the vehicle wheel.

The drawings show a diagram of a device for lubricating the flanges of wheel sets.

A device for lubricating the flanges of a wheel pair of a rail vehicle (FIGS. 1, 2) is proposed, comprising a reservoir 1, a flexible oil pipe 2, a lubricating element in the form of a piece of rubber pipe 3, with a solid lubricant rod 4 located inside the pipe, the pipeline 2 is installed with an inclination from the reservoir 1 to the lubricating element 3, and the rod 4 is spring-loaded with a spring 5 to the lubricated wheel flange, the base of the rod 4 is located in the glass 6, which is pivotally mounted, with the possibility of turning company in the plane of rotation of the wheel around an axis parallel to the axis of the wheelset, and coaxially with a spring 7 spring-loaded relative to the cup and mounted with the possibility of longitudinal movement of the fitting 8 of the supply flexible oil pipe 2, while the axis of rotation of the cup 6 is fixed to the bracket 9 motionless, the fitting 8 is fixed on the bracket 9 with the possibility of longitudinal movement along the grooves G of the bracket 9, the bracket 9 is mounted with the possibility of longitudinal movement along the guides 10 of the sleeve 11, and the sleeve 11 is fixed relative to the cart of the wheelset (not indicated in the drawing).

The device operates as follows.

While the vehicle is parked, the device is in the initial position (Fig. 1): the rod 4 of the lubricating element is pressed by the spring 5 to the wheel flange, the cup 6 with the nozzle 8 are on the same axis and pressed against each other by the force of the spring 7, the outflow of oil from the nozzle 8 of the oil pipeline does not occur, since the opening of the nozzle 8 is blocked by the pressed end of the glass 6.

The vehicle begins to move (Fig. 3), the wheel begins to rotate, the wheel flange due to the frictional force carries the tail of the rod 4 and shifts it in the direction of rotation of the wheel. The glass 6 is rotated by a certain angle, squeezing the nozzle 8 at a certain distance, thus opening the hole of the nozzle 8 for the oil to flow into the sleeve 11, from it into the rubber pipe 3 and then onto the wheel flange.

When the vehicle stops, when the rotation of the wheel ceases to deflect the tail of the rod 4 from its original position, the force of the spring 7 returns the nozzle 8 to its original position, while the end of the nozzle 8 presses on the rotated end of the nozzle 6, and, overcoming the force of the spring 5, the rod 4 comes in the initial longitudinal position (Fig. 1), the end face of the glass 6 overlaps the hole of the nozzle 8, the flow of oil stops.

When the device is operating, it is important to adjust the magnitude of the compression force of the springs 5 and 7, as well as the ratio of this force to the friction force of the shank of the rod 4 on the wheel flange.

Determining is the fact that the friction force of the shank of the rod 4 on the wheel flange has a variable value depending on the presence of lubricant on the wheel flange.

In the initial position, when the ridge is not lubricated, the friction force is greater and the force to deflect the rod 4 is greater - the device begins to supply lubricant to the ridge.

By the time it stops, when the flange is abundantly lubricated, the friction force is insignificant, and the force of the spring 7 is sufficient to return the rod 4 to the longitudinal position and press the end of the cup 6 to the end of the sleeve 8 - the device blocks the lubricant supply to the wheel flange.

The self-regulating effect of the lubricant supply to the wheel flange of a rail vehicle is based on this principle. With an excess of lubricant on the flange, the device reduces the amount of oil supplied to the lubricating element. With a lack of lubrication, as well as an increase in wheel speed, the device increases the oil supply to the lubricating element.

When conducting a search on patent and scientific and technical information, no solutions were found containing the totality of the proposed features, which allows us to conclude that the criteria of "novelty" and "inventive step" are met.
