Device for applying conditioning agent to the wheels of railway vehicles

Abstract

A conditioning device for applying conditioning agent to the wheel face (46) and wheel back surface (47) of wheels (39) of railway vehicles comprises at least one brush (20) with bristles, a support (14) on which the brush (20) is mounted and which has a bearing surface (27) with which it rests, for example, on a sleeper (2) of a track (3), and a line (48) for supplying the conditioning agent to the brush (20). The line (48) opens between the bristles of the brush (20). This ensures good distribution of the conditioning agent within the brush and good transfer of the conditioning agent to the wheel face (46) and wheel back surface (47).

Description

[0001] The invention relates to a conditioning device for applying conditioning agent to the wheel face and / or the wheel back surface of wheels of rail vehicles or railway wagons, comprising at least one brush with bristles, a carrier on which the brush is mounted and which has a bearing surface with which it rests on a sleeper of a track, and a line for supplying the conditioning agent to the brush.

[0002] The invention further relates to a braking system with such a conditioning device.

[0003] Track brakes, also known as shoe brakes, are used in marshalling yards and shunting yards to reduce the speed of wagons and slow them down to the desired speed. These systems are permanently installed on the rail. Deceleration occurs through contact and friction between the brake shoes or brake bars with wear strips and the wheel's flanks (front and back surfaces). However, this process also generates high-frequency noise.

[0004] To prevent or at least reduce this noise, a conditioning agent is used to maintain the coefficient of friction between the wheel and the brake shoe. The conditioning device applies the agent to the wheel flanks, from where it is distributed to the brake shoes in the braking system to minimize noise generation.

[0005] A conditioning device of this type is known from JP 2015-080978 A. In this conditioning device, the conditioning agent is supplied via nozzles at the base of the brush. If no solid parts of the conditioning device enter the clearance profile of the rails or...

[0006] Since the brushes are intended to protrude over tracks, it is necessary to raise them relatively steeply, which, however, makes it more difficult to distribute the conditioning agent towards the free ends of the bristles, through which the conditioning agent is applied to the wheels.

[0007] Another conditioning device is known from EP 2 807 068 A. In the known device, the conditioning agent is indeed supplied in the area of ​​the free end of the bristles, but the distribution of the conditioning agent is also deficient because the nozzles are arranged above the brushes and thus the conditioning agent is not distributed by the brushes onto the flanks of the wheels on the wheel sections that move upwards away from the nozzles and the brush sections located below them.

[0008] The invention is based on the objective of creating a conditioning device of the type mentioned above, which enables a better distribution of the conditioning agent onto the flanks of the wheels and subsequently an application of the conditioning agent between the wheel and brake shoes.

[0009] This problem is solved with a conditioning device having the features of claim 1.

[0010] This problem is solved with a braking system having the features of claim 17.

[0011] Preferred, but not essential, features are the subject of the dependent claims.

[0012] According to the invention, the preferably flexible line for supplying the conditioning agent to the brush opens between the bristles of the brush. This has the advantage that the conditioning agent is reliably distributed on the flanks of the wheels by means of the brush, because the conditioning agent is dispensed in the brush and bristles are located around the opening of the line, which distribute the conditioning agent.

[0013] Furthermore, the nozzle of the line is set back from the free ends of the bristles by no more than 50% of the bristle length. This ensures that the conditioning agent is reliably distributed between the bristles within the brush before being applied evenly to the wheel flanks.

[0014] According to the invention, the opening of the tube is set back from the free ends of the bristles by at most 50% of the bristle length, because good distribution of the conditioning agent in the front region of the brushes is possible in this area. The distribution is even better if the opening of the tube is set back from the free ends of the bristles by 40% to 10%, preferably 30% to 10%, and particularly preferably 20% to 10%.

[0015] As a general rule, a distribution of the conditioning agent within the brush in a front area of ​​the brush is better than a distribution in a more rear area, but the opening should be set back slightly from the free ends of the bristles to ensure good distribution of the conditioning agent between the bristles.

[0016] A preferred embodiment of the invention is characterized in that the brush has bundles of bristles, and that the cable terminates between the bundles of bristles. When the bristles are bundled, the brush is stiffer on the one hand, and on the other hand, it is easier to insert the cable between the bristles.

[0017] In a further preferred embodiment of the invention, if the cable lies essentially parallel to the bristles, this has the advantage that, if flexible, the cable can easily move along with the bristles or bristle bundles when a wheel moves past the brush. Furthermore, inserting the cable into the brush is also easier if it lies essentially parallel to the bristles.

[0018] In the invention, it is further preferred if two or more than two channels terminate between the bristles of the brush. This not only improves the distribution of the conditioning agent within the brush, but is particularly advantageous for longer brushes to ensure good distribution of the conditioning agent over the entire length of the brush.

[0019] In a particularly preferred embodiment of the invention, the conduit is more rigid than the bristle bundles. The resulting advantage is that the conduit opening moves between the bristles or bristle bundles when the bristles are bent to the side by a passing wheel, thus distributing the conditioning agent more effectively between the bristles.

[0020] A further disadvantage of the device known from EP 2 807 068 A is that the device described therein, with its metallic components, protrudes into the track's clearance gauge, which must normally be kept clear of all fixed parts. Furthermore, fixed parts of the conditioning device come into contact with the train's wheel. This causes these parts to be displaced by the wheel and thus subjected to acceleration. Consequently, wear occurs on all contacted guide elements, and the energy of the accelerated masses must be absorbed and dissipated by the supports. Should the displacement of the device's components fail, this can lead to damage to the wheel. Therefore, a special permit is required for the installation of this device.

[0021] A further object of the invention is therefore to create a conditioning device in which no solid parts protrude into the clearance profile of the rails or tracks.

[0022] This task is best solved by combining the following features, although each individual feature is also suitable for solving this task on its own and can therefore be used without the other features: The angle at which the bristles of the brush are aligned to the support surface is adjustable; the position of the brush relative to the carrier is adjustable, in particular movable; the brush is arranged on a holder and is in particular adjustable on the holder, in particular movable.

[0023] Each of these measures makes it possible to arrange the fixed metallic components of the conditioning device in such a way that only the bristles of the brush and the preferably flexible cables, which may move along with the bristles, protrude into the clearance profile of the track.

[0024] In a further development of the invention, the holder may also have a mounting surface on which the brush is mounted, and the brush may be adjustable, in particular slidable, on the mounting surface. This allows for easy positioning of the holder on the support, particularly to readjust the brush in case of wear associated with shortening of the bristles.

[0025] The invention has also proven advantageous if the angle between the bristles and the contact surface is adjustable between 0° and 45°, particularly between 10° and 35°, and most preferably between 15° and 30°. These angles make it particularly easy to keep the clearance profile clear while simultaneously ensuring reliable application of conditioning agent to the wheels.

[0026] A particularly simple design of the conditioning device according to the invention is characterized in that the bristles are aligned parallel to the mounting surface, and that the holder is pivotably attached to the support. Adjusting the distance of the brush from the rail and consequently from the wheels running on it can thus be carried out very easily, especially if the brush is arranged on a holder and, in particular, adjustable on the holder, especially sliding, because the orientation of the brush always remains the same during adjustment and readjustment due to wear.

[0027] If two or more than two lines terminate between the bristles of the brush, the brush according to the invention conveniently has a base part to which the bristles are attached, and a distribution block for the conditioning agent is arranged on the base part, to which the lines and a supply line for the conditioning agent are connected.

[0028] In a further development of the invention, a drip tray can be arranged vertically under the bristles of the brush, particularly under the free ends of the brush, and a hose guide for the supply line for the conditioning agent to the brush can be arranged on the drip tray. In this way, separate protection for the supply line is unnecessary.

[0029] Finally, the invention can also include a sound sensor, which is preferably arranged in the immediate vicinity of the braking device and preferably connected to a control unit for a pump for the conditioning agent. This allows, on the one hand, the effectiveness of the conditioning device according to the invention to be detected and recorded, and on the other hand, the amount of conditioning agent supplied to the brush to be controlled depending on the noise level.

[0030] Further features and advantages of the invention will become apparent from the following description of a preferred embodiment of the invention, which does not limit the scope of protection, with reference to the accompanying drawings. These show: Fig. 1 shows an overview plan with conditioning devices according to the invention, Fig. 2 shows a conditioning device according to the invention viewed in the longitudinal direction of a rail, Fig. 3 shows a perspective view of a part of the conditioning device. Fig. 1 , Fig. 4 an enlarged view of a section of Fig. 2 Fig. 5 a holder according to the invention without a cover, Fig. 6 a support according to the invention, Fig. 7 a section through a brush according to the invention, Fig. 8 a side view of the brush according to the invention, Fig. 9 an exploded view of the brush according to the invention, Fig. 10 a rail with part of the conditioning device according to the invention and sensors, and Fig. 11 a track system with a conditioning device according to the invention and a track brake.

[0031] The drawings show an embodiment of a device according to the invention, which is only exemplary and, apart from the features of the invention as defined in the claims, can also be designed differently with respect to many components within the scope of the present invention, without this needing to be mentioned in detail below.

[0032] Fig. 1 Figure 1 shows an overview of a system according to the invention with conditioning devices 1 according to the invention, which are arranged on both sides of rails 2 of a track 3. The number of conditioning devices 1 arranged one behind the other in the longitudinal direction of the rails 2 is variable according to the respective requirements. That is, in the longitudinal direction of the rails 2, there can also be only a single conditioning device 1, two (as in Figure 2) Fig. 1 shown) or more than two conditioning devices 1.

[0033] In Fig. 1It can be seen that identical conditioning devices 1 are arranged on both sides of both rails 2. However, within the scope of the invention, a conditioning device 1 according to the invention can also be arranged only on one inner or outer side of one or both rails, optionally in combination with conditioning devices that are constructed differently.

[0034] As in Fig. 1As can be seen, a control unit 5 and a container 6 for a conditioning agent, as well as a pump 7 for the conditioning agent and a power supply 8, are housed in a system box 4. The pump 7 is connected to distribution boxes 11 via main lines 9. In the distribution boxes 11, the main lines 9 are divided into individual supply lines 12 via distribution elements. These supply lines 12 are connected to the conditioning devices 1. Each conditioning device 1 is supplied by its own supply line 12. In the inlet area of ​​the system, two wheel sensors 13 are arranged on a rail 2 ( Fig. 10 ), so that the direction of travel of railway carriages can be determined.

[0035] In the illustrated embodiment, the conditioning devices 1 have a carrier 14 on which a holder 15 is mounted via a pivot axis 16 ( Fig. 7The support 14 is movably mounted. A brush 20 is mounted on the bracket 15. The support 14 is screwed onto a sleeper 18 by means of a ribbed plate 17, to which it may, for example, be welded. The ribbed plate 17 rests on the sleeper 18 with a bearing surface 27. If the support 14 is permanently connected to the ribbed plate 17, the bearing surface 27 can be considered the bearing surface of the support 14. However, the support 14 can also have its own bearing surface if, for example, it is not permanently but detachably connected to the ribbed plate 17 or is connected in some other way to a sleeper 18 or another part of the track 3.

[0036] If a conditioning device 1 is arranged on both sides of a rail 2, which is common practice but not mandatory, then it is preferred if both conditioning devices 1 are mounted on a common ribbed plate 17. The ribbed plate 17 also serves, in a manner known per se, to fasten the rail 2 to the sleeper 18.

[0037] The support 14 has a support element 19 which is arranged on the support 14, e.g. by means of a through a in Fig. 6 visible bore 28 guided screw 30 ( Fig. 9 ) screwed on.

[0038] On the top of the holder 15 there is a mounting plate 25 with a mounting surface 26 on which the brush 20 is mounted.

[0039] In Fig. 7The pivot axis 16 can be seen, which is formed by a hinge pin 41 of a hinge 42, one leg 43 of which is attached to the support element 19 and the other leg 44 to the mounting plate 25.

[0040] The support element 19 has two legs 21 pointing towards the rail 2, each of which has a bore. Two legs 22 pointing towards the sleeper 18 are arranged on the bracket 15. These legs lie parallel to the legs 21 of the support element 19 and each has an elongated hole 45. Screws 23 are inserted through the bore and the elongated holes 45 of the legs 21 and 22.

[0041] Height-adjustable screws 24 are arranged on the bracket 15, preferably screwed through the mounting plate 25 of the bracket 15, which are supported on the legs 21 of the support element 19. The angle α at which the mounting surface 26 of the bracket 15 is inclined relative to a horizontal plane, in this embodiment relative to the top of the threshold 18 or bearing surface 27, can be adjusted using the height-adjustable screws 24. The position of the bracket 15 on the support 14 can be fixed by tightening the screws 23.

[0042] The angle α is preferably between 0° and 45°, but could theoretically be larger. If there are no issues with the clearance gauge of track 3, the angle can also be 0°, which has the advantage that the bristles can be aligned at a right angle to the flanks 46, 47 of the wheels 39. Above 45°, the angle between the flanks 46, 47 and the bristles becomes very shallow, which can be somewhat disadvantageous, but might be necessary due to spatial constraints. Angles α between 10° and 35° are therefore preferred, because in this angle range there are usually no issues with the clearance gauge of track 3, and the angle between the flanks 46, 47 of the wheels 39 and the bristles of the brush 20 is well suited for reliable transmission. For these reasons, an angle range between 15° and 30° is particularly suitable.In general, taking into account the clearance profile of track 3, a smaller angle α is preferable to a larger one, because the conditioning agent then does not have to be moved upwards so strongly against gravity in the brush 20.

[0043] Brush 20 shows, as in particular the Fig. 4 and 5The figure shows a base part 31, over which a cover 32 is located. On the bottom 33 of the base part 31 are elongated holes 34 oriented towards the rail 2, through which screws 35 are inserted and screwed into the mounting plate 25. By sliding the base part 31 of the brush 20 towards the elongated holes 34 on the mounting surface 26, the distance of the brush 20 from the rail 2 can be adjusted and fixed using the screws 35. This is advantageous both for the initial adjustment of the brush 20's position and for compensating for brush wear. The cover 32 has laterally projecting tabs 40 with which it is screwed to the mounting plate 25 using screws 29. The base part 31 can be moved independently of the cover 32 on the base plate 32 after the cover 32 has been removed from the mounting plate 25 and access to the screws 35 has been gained.

[0044] Bristles are attached to a wall 36 of the base part 31, which may be permanently or interchangeably connected to the base part 31. In the illustrated embodiment, these bristles are grouped into bundles 37. The bundles 37 are oriented essentially parallel to the mounting surface 26 and at right angles to the rail 2. The free ends 38 of the bristles or bundles 37 point towards the area above the rail 2 where the flanks 46, 47 of passing wheels 39 are located and come into contact with them.

[0045] Between the bundles 37, or instead of one or more bundles 37, at least one line 48 is arranged; in the illustrated embodiment of the invention, there are two lines 48, which lie essentially parallel to the bundles 37 and carry the conditioning agent to the bristles, preferably between them, or to the bundles 37. Fig. 4The free space 50 is visible, in which the conductors lie instead of a bundle 37. The conductors 48 pass through the wall 36 and are held in it. The openings 49 of the conductors 48 are set back from the free ends 38 of the bundles 37 and therefore terminate within the brush 20 or in the space between the bundles 37. Although it would also be possible in the invention for the openings 49 to terminate closer to or directly in the area of ​​the free ends 38 of the bristles, which would be preferable, for example, with a larger angle α, the embodiment shown in the drawings is preferred because the conditioning agent is then better distributed between the bristles before it is transferred to the flanks 46, 47 of the wheels 39.

[0046] If the lines 48 are alternatively or additionally stiffer than the bundles 37, then they move less than the bundles 37 when the flanks 46, 47 of a wheel 39 bend the bundles 37 to the side as they pass by, so that the bundles 37 lying next to the openings 49 of the lines 48 brush past the openings 49, which also improves the distribution of the conditioning agent in the brush 20.

[0047] A distribution block 51 is attached to the base 33 of the base unit, to which both the lines 48 and one of the supply lines 12 are connected. The conditioning agent is distributed from the supply line 12 to the two lines 48 within the distribution block 51.

[0048] The cover 32 of the brush 20 ensures that the distribution block 51 with the lines 48 and the supply line 12 in the brush 20 is protected from external influences.

[0049] In Fig. 2The areas 52 and 53 are shown where the flanks 46 and 47 of the wheels 39 of the rail vehicles are usually located, since the flanks 46 and 47 of the wheels 39 are not always in the same position due to the sinusoidal motion and the varying width of the wheels 39. By moving the brushes 20 along the mounting surface 26 towards and away from the rails 2, and by pivoting the brackets 15 about the pivot axes 16, the free ends 38 of the brushes 20 can be perfectly adjusted in areas 52 and 53.

[0050] Furthermore, by tilting the brackets 15, it is possible to position the fixed parts (in particular the base part 31 and the cover 32 of the brushes 20 as well as the bracket 15) of the conditioning device 1 according to the invention lower than the free ends 38, so that they can be arranged outside the clearance profile of the track 3.

[0051] Below the brushes 20 are drip trays 54, which protect the track bed from contamination by the conditioning agent. A hose guide 55 for the supply lines 12 is arranged on the drip tray 54, thus eliminating the need for separate protection of the supply lines 12 in this area.

[0052] In the area of ​​the brakes not shown in the drawings, a sound sensor 56, e.g., a microphone, can be arranged to record sound vibrations, in particular structure-borne sound vibrations of the rail, the signals of which can be recorded and filtered out, in particular, for anomalies in the frequency range of 1 kHz to 12.5 kHz, such as squealing sounds. Based on the measured or evaluated signals, the effectiveness of the conditioning device 1 according to the invention can be checked and, if necessary, the amount of conditioning agent supplied can also be changed.

[0053] Fig. 11Figure 1 schematically shows a track system with a braking system 57 comprising a shoe brake 58 and a conditioning device 1 according to the invention. At least one shoe brake 58 with brake shoes 59 is arranged on each rail 2. These shoes engage the wheel face 46 and the wheel back face 47 of the wheels 39 of a rail vehicle and are arranged behind the conditioning device 1 in the direction of travel 59. The conditioning device 1 applies the conditioning agent to the flanks 46 and 47 of the wheels 39, which then distribute it to the brake shoes 59 in the braking system 57 to minimize noise generation.
