Definitions
- the present invention concerns a lubricant applicator for a wheel of a trackbound vehicle, which applicator comprises an applicator cylinder for a lubricant stick.
- the present invention also concerns a method of lubricating a wheel of a trackbound vehicle with the help of a lubricant applicator which comprises an applicator cylinder for a lubricant stick.
- a wheel intended for a railway carriage, a railway engine, a railcar, or some other trackbound vehicle has a tread surface, which is intended for rolling against the upper part of that rail over which the wheel is to roll, and a flange, which is responsible for the guiding against the rail, such that the trackbound vehicle does not leave the rails.
- US 5,054,582 describes a lubricant applicator which is arranged to press a solid lubricant stick against that position on a wheel where a tread surface and a flange are joined in order to decrease the friction described hereinbefore.
- a purpose of the present invention is to provide a lubricant applicator for application of lubricant on a flange which is comprised in a wheel for a trackbound vehicle, which lubricant applicator requires little maintenance.
- a lubricant applicator for a wheel of a trackbound vehicle which applicator comprises an applicator cylinder for a lubricant stick, characterized in that the lubricant applicator further comprises a piston, which is arranged to run in the applicator cylinder and to press the lubricant stick against said wheel, and a space inside the applicator cylinder which is arranged to receive a pressurized fluid for pressing the piston against the lubricant stick.
- An advantage of this lubricant applicator is that a reliable lubrication is ensured.
- a further advantage is that the pressure with which the stick is pressed against the wheel is substantially independent of how worn the stick is.
- the applicator cylinder has a circular cross-section.
- An advantage of this embodiment is that efficient sealings between the applicator cylinder and lubricant stick can be easily achieved, with the help of, for example, O-rings.
- a control device is arranged to receive at least one signal from a sensor, which senses at least one operating parameter of the trackbound vehicle, and to control the pressure of the pressurized fluid supplied to the space depending on this signal.
- An advantage of this embodiment is that it becomes possible to apply lubricant depending on the present need for lubricant. In for example curves more lubricant can be applied, and less lubricant may be applied at straight stretches. This reduces the average consumption of lubricant.
- both the lubricant stick and the applicator cylinder are formed from electrically conductive material and are in electric contact with each other, wherein currents that pass from a rail to said wheel can be conducted via the lubricant stick and the applicator cylinder further to the trackbound vehicle.
- the lubricant stick is formed from a material comprising graphite.
- Graphite has the advantage that it both has lubrication qualities and is also electrically conductive.
- a part of the lubricant stick forms that piston which runs in the applicator cylinder.
- a separate piston is arranged to run in the applicator cylinder and to be pressed against the lubri- cant stick.
- the applicator cylinder is releas- ably attached to a bracket which is mounted on the trackbound vehicle.
- a further purpose of the present invention is to provide an efficient and reliable method of applying lubricant to a wheel of a trackbound vehicle.
- This purpose is achieved by means of a method of lubricating a wheel of a trackbound vehicle with the help of a lubricant applicator which comprises an applicator cylinder for a lubricant stick, wherein the lubricant applicator further comprises a piston, which is arranged to run in the applicator cylinder and to press the lubricant stick against said wheel, and a space inside the applicator cylinder which is arranged to receive a pressurized fluid for pressing the piston against the lubricant stick, wherein at least one operating parameter which describes the present operating condition of the trackbound vehicle is measured, and that the pressure in said space is adapted to provide a desired lubrica- tion of said wheel with regard to said present operating condition.
- An advantage of this method is that an efficient and controlled lubrication of the wheel is achieved.
- said at least one operating parameter comprises at least one of the present curve position of the trackbound vehicle and the present speed of the trackbound vehicle.
- the curve position that is, whether the vehicle is in a curve or not, and how tight such curve is, and the speed are two of those parameters that have the largest influence on the need for lubrication.

- Fig. 3 is an enlarged view and illustrates the portion III illustrated in fig.2a.
- Fig. 4 is a side view, and shows schematically a control system com- prised in the lubricant applicator.
- Fig. 5 is a cross-section and shows a lubricant holder according to an alternative embodiment, as seen from the side thereof.
- Fig. 1 illustrates a lubricant applicator 1 in accordance with one embodiment of the present invention.
- the lubricant applicator 1 has a lubricant holder 2 and a control system 4, both of which are to be described in more detail hereinafter.
- the lubricant applicator 1 is arranged for pressing a solid lubricant stick 6 against a wheel 8, the outer portions of which are illu- strated in fig. 1, of a trackbound vehicle, such as a railway engine, a railway carriage, a railcar, a tram, etc, .
- the wheel 8 has a tread surface 10 which is arranged for rolling against the upper side of a rail 12.
- the wheel 8 also has a flange 14 which guides the position of the wheel 8 in relation to rail 12.
- the lubricant holder 2 of the lubricant applicator 1 is mounted on the trackbound vehicle 9, schematically illustrated in fig. 1 , and presses the stick 6 against the wheel 8 in that position on the wheel 8 where the tread surface 10 passes on to the flange 14, a position which can be called the root 16 of the flange 14, for the purpose of reducing the friction between the flange 14 and the rail 12.
- the lubricant holder 2 will now be described in more detail with reference to fig. 2a and fig. 2b. Fig.
- FIG. 2a illustrates the lubricant holder 2 in more detail, as seen in cross-section and from the side thereof.
- Fig. 2b illustrates the lubricant holder 2 as seen in a cross-section I Ib-I Ib illustrated in fig. 2a.
- the lubricant holder 2 has a bracket 20, which is provided with two openings 22.
- the openings 22 are intended for receiving bolts, not shown, for holding the bracket 20 on the fig. 1 schematically illustrated trackbound vehicle 9.
- the bracket 20 is provided with a shelf 24, which is open in the middle.
- An applicator cylinder 26 abuts this shelf 24, as is best illustrated in fig. 2b.
- Two releasable cotters 28 hold the applicator cylinder 26 pressed against the shelf 24.
- the lubricant stick 6 runs inside the applicator cylinder 26.
- the applicator cylinder 26 as well as the lubricant stick 6 has preferably circular cross- section, as is best illustrated in fig. 2b, but may also have another cross-section, such as a square cross-section, triangular cross-section, oval cross-section etc.
- the applicator cylinder 26 has, as is clear from fig. 2a, a gable 30 and a connection opening 32 for connection of a pipe 34.
- the gable 30 is provided with an all around running outer track 31 in which the rear cotter 28 can engage, which means that the applicator cylinder 26 is locked also in its longitudinal direction.
- the pipe 34 is intended for supply of pressurized fluid to the applicator cylinder 26.
- This pressurized fluid may advantageously be pressurized air, but may also be hydraulic oil, nitrogen gas, water, or some other suitable fluid.
- the rear part of the solid lubricant stick 6 is arranged for functioning as a piston 36 inside the applicator cylinder 26.
- a pressurized fluid for example pressurized air
- this fluid will, via the pipe 34 and the connection opening 32, enter a cylinder space 37, which is formed between the piston 36, the gable 30 and the walls of the applicator cylinder 26, and press the piston 36, i.e. the lubricant stick 6, against the root 16 of the flange 14 and provide the desired lubrication.
- a part of the lubricant stick 6, and rather its rear part forms that piston 36 which under influence of the pressurized fluid in the space 37 presses the lubricant stick 6 against the wheel 8.
- Fig. 3 illustrates the portion III illustrated in fig. 2a in more detail.
- the applicator cylinder 26, which is squeezed between the shelf 24 and cotter 28, has at its front end 38 a sealing case 40, which is attached to the front end 38 of the cylinder 26 by means of a threaded connection.
- the sealing case 40 the interior cross-section of which is circular, has an internal track 42 in which a sealing 44 has been arranged.
- the sealing 44 is suitably a circular sealing ring, such as a so-called CD- ring , for example made of rubber material, and provides a sealing between the case 40 and the stick 6.
- the sealing 44 has two purposes.
- One purpose is to provide a sealing between the stick 6 and the applicator cylinder 26 such that pressurized fluid which is supplied to the cylinder space 37 does not leak out there from.
- the other purpose is to provide a sealing such that dirt, for example dust, water, snow, etc, that whirl up around the wheel 8 cannot enter the interior of the applicator cylinder 26 and cause operating problems caused by the stick (6) not being able to slide in the desired manner inside the cylinder 26.
- the applicator cylinder 26 is, according to a preferred embodiment, formed from an electrically conductive material, such as a metal, for example steel. Furthermore the lubricant stick 6 is in accordance with this preferred embodiment also formed from an electrically conductive material. An example of such material which is both electrically conductive and has good lubricating qualities is graphite. According to this preferred embodiment electric current can be conducted from the rail 12 to the wheel 8, further from the wheel 8 to the stick 6 and from there via the applicator cylinder 26 and the bracket 20 directly to the trackbound vehicle 9. In this case the lubricant applicator 1 also works as a ground connection.
- An advantage of this is that electric current need not be conducted via bearings of the wheel 8, or at least needs to be conducted via bearings of the wheel 8 to a limited extent, which reduces the risk of current damages to these bearings.
- Electric contact between the stick 6 and the applicator cylinder 26 normally arises by itself, since the stick 6 normally will be somewhat inclined inside the applicator cylinder 26, such that there will be electric contact between the applicator cylinder 26 and the stick 6.
- it may be suitable to improve this electric contact by means of for example a contact ring 43 made from a conductive material.
- Fig. 4 illustrates the control system 4 of the lubricant applicator 1 in more detail.
- a control device 46 such as a computer, microprocessor, or similar, receives signals from a number of sensors describing the present operating conditions of that trackbound vehicle on which the lubricant applicator 1 is mounted. Among other things the control device 46 receives signals from a curve sensor 48, which senses whether the trackbound vehicle turns, and in such case how much, or if it runs straight ahead. The control device 46 receives signals from the curve sensor 48 and calculates, based on these signals, the magnitude of the need for lubrication.
- the friction between the flange 14 of the wheel 8 and the rail 12 is normally at its largest upon cornering, and thereby the need for lubrication is largest when the vehicle is in a curve.
- the control device 46 sends signals to a control valve 50 which is arranged on the pipe 34, which at one end is connected to the gable 30 of the applicator cylinder 26. At its other end the pipe 34 is connected to a supply of pressurized fluid, not shown, for example the pipe 34 may be connected to a pressure tank for pressurized air.
- control device 46 When the control device 46 receives signals from the curve sensor 48 that the trackbound vehicle has entered a curve the control device 46 sends a signal to the control valve 50 that it should open.
- pressurized fluid such as pressurized air
- the control valve 50 opens pressurized fluid, such as pressurized air, flows into the cylinder space 37 and exerts, thanks to the pressure that arises in the space 37, a pressure against the piston 36, i.e. against the stick 6, which thereby will be pressed against the root 16 of the flange 14 and generate the lubrication that is needed in the curve.
- control device 46 When the control device 46 then receives signals from the curve sensor 48 that the trackbound vehicle has again entered a straight portion of the track the control valve 50 is closed again.
- the pressure in the space 37 decreases again. This can either occur gradually by the pressurized fluid slowly leaking out through the sealing 44, illustrated in Fig. 3, or by the pressurized fluid being evacuated through a separate pipe 52, which is provided with an evacuation valve 54 that is controlled by the control device 46.
- the pressure in the space 37 decreases again the force with which the stick 6 is pressed against the root 16 of the flange 14 will decrease, and thereby the lubrication also decreases.
- control device 46 controls the supply of lubricant in such a manner that lubricant is supplied to the wheel 8 when it is needed, for example at cornering, but is not supplied when there is no need for lubricant, for example in straight stretches.
- the control device 46 can also be arranged to control the pressure gradually depending on how tight the present curve is.
- the control device 46 can be arranged to control the control valve 50 to supply a first pressure at moderately tight curves, and can be arranged to control the control valve 50 to supply a second pressure, which is higher than the first pressure, at very tight curves.
- the control device 46 can also be arranged to continuously control the pressure in the space 37 depending on the signal from the curve sensor 48, for example according to the principle of a PID regulator.
- the control device 46 can also be arranged to achieve a certain lubrication also at straight stretches, if that is desired, wherein this lubrication is normally smaller than the lubrication in cornering.
- the control device 46 may also receive other signals, for example concerning the speed of the trackbound vehicle, the ambient temperature, etc, and allow these signals to influence the degree of opening of the control valve 50.
- the space 37 will be larger. Thanks to the fact that the pressure of the fluid supplied to the space 37 is controlled to the same value at a certain operating condition, regardless of how long the stick 6 has been used, the pressure with which the stick 6 is pressed against the root 16 of the flange 14 will be the same, at the same setting of the control valve 50, regardless of whether the stick 6 is almost new, or if the stick 6 is almost worn out.
- the lubricant stick 6 When the lubricant stick 6 is worn out it can easily be changed. This is made by releasing the pipe 34 shown in fig. 2a from the gable 30. Then the cotters 28 illustrated in fig. 2a and 2b are released and the applicator cylinder 26 is removed from the shelf 24 of the bracket 20. Then a new applicator cylinder 26, which has a pre-mounted lubricant stick 6, is mounted in the bracket 20 with the help of the cotters 28. The old applicator cylinder 26 is sent away for maintenance, check and mounting of a new lubricant stick 6.
- the wear part which is changed is, hence, a complete unit which comprises applicator cylinder 26 and lubricant stick 6 and which is easily mounted in the bracket 20 being fixedly mounted on the trackbound vehicle. Hence safe function and quick changes are ensured. It is realized that it is also possible to, as alternative to changing said complete unit, at a change release the applicator cylinder 26, take out the remaining stub of the lubricant stick 6, and to push a new stick 6 into the applicator cylinder 26, which is then again mounted in the bracket 20.
- Fig. 5 illustrates a lubricant holder 102 according to an alternative embodiment.
- the holder 102 has a bracket 120, which is of the same type as the bracket 20 described with reference to fig. 2a and fig. 2b and is arranged to retain, in a similar manner, an applicator cylinder 126, which preferably is cylindrical.
- an applicator cylinder 126 In its rear part 127 the applicator cylinder 126 has a gable 130 and a connection opening 132 for connecting a pipe 134 intended for supplying a pressurized fluid to the applicator cylinder 126.
- the applicator cylinder 126 illustrated in fig. 5 has a completely separate piston 136.
- the separate piston 136 is provided with a sealing ring 145 which seals the piston 136 to the inner walls of the cylinder 126.
- a pressurized fluid such as pressurized air
- pressurized air When a pressurized fluid, such as pressurized air, is supplied to the applicator cylinder 126 this fluid will enter a cylinder space 137 which is formed between the piston 136, the gable 130 and the walls of the cylinder 126, and to press the piston 136 against a lubricant stick 106, which is thereby pressed against the root 16 of the flange 14 and achieves the desired lubrication.
- the applicator cylinder 126 is provided with a sealing ring 144 which seals against the stick 106.
- the main task of the sealing ring 144 is to prevent dirt from entering the applicator cylinder 126.
- the sealing ring 144 may also work as a stop which retains the piston 136, and thereby the fluid in the space 137, inside the cylinder 126 when the stick 106 has been completely worn out.
