Description

Vibration absorber device.

Prior art

The present invention relates to a oscillation absorber arrangement to install so minus an oscillation absorber on a rail, as claimed in the preamble of claim 1, as known from document DE 299 09 351 U1.

An oscillation absorber arrangement whereby a first oscillation absorber can be install on a rail foot and a second oscillation absorber It can be installed on a rail core known from the model German utility DE 297 14 904 U1.

Document DE 31 13 268 C2 describes an oscillation absorber that is suitable for this purpose, for sound absorption, which has a waveguide in the form of a horn part that narrows in the direction of wave propagation. , which can be connected at least at the wide end with a snap fit on the body to be dampened, and which has a damping material at least in the narrowest end zone. The waveguide has a sequence of layers, which alternate in the direction of wave propagation, of flexible spring elements and solid mass elements, with the elastic constant of the spring elements and the manes
sas of the mass elements decreasing continuously from the widest end of the waveguide.

Figure 4 shows a side view schematic parallel to the rail of the absorber arrangement of oscillations known from the German utility model DE 297 14 904 U1.

The system is used to absorb oscillations in particular on iron rails or tram rails. He sound supported by the structure that originates from the rail and the sound that supports the air caused by the rail are intended reduce this way.

An oscillation absorber 1 is fixed with a snap fit under the foot of rail 7 to cushion Vertical oscillations This is fixed to a metal plate solid 8 ', in which the mass systems are installed individual elastics, which are in the form of waveguides that are They narrow in the direction of wave propagation. Plate metal 8 'is connected to the foot of rail 7 by means of a clamp 3 'support.

An additional oscillation absorber 2 is fixed against the soul of rail 6 with fasteners and / or 4 'elastics to cushion horizontal oscillations in the rail head 5 and in the soul 6.

The base plate 9 'which, as in the first oscillation absorber 1, comprises a solid metal plate, produces a very good swing link on the rail thanks to this type of fit, that is, the oscillations that have to be absorb are introduced directly into the absorption system Due to the very rigid connection. Irregular areas of the rail do not they have no effect on the effectiveness of the absorber, due to the solid construction of the absorber base plates.

That known arrangement of the absorber of oscillations have the disadvantage that it implies a certain amount of installation complexity and that are exercised large lateral forces on the fixing screws that connect the clamps 3 'to the base plate 8'.

Figure 5 shows a side view schematic parallel to the rail of the absorber arrangement of oscillations known from the German utility model DE 299 09 351 U1.

The oscillation absorber arrangement shown in figure 5 has a corrugated plate 8 which is arranged below the foot of rail 7, so that its two nerves 10 are arranged essentially parallel to both sides of the rail. An oscillation absorber 1 is arranged so transverse to the rail, below the corrugated plate 8. The support clamps 3 are installed in each of the two ribs 10 by threaded bolts 12, which are anchored in the ribs 10, and corresponding threaded nuts 11.

Support bracket 3 on the right shown in figure 5 is supported directly on the foot of rail 7. Support bracket 3 on the left illustrated in Figure 5 is supported on a first end of a clamp clamping 4, whose second end presses an absorber of additional oscillations 2 against the soul of rail 6. The first end of the clamp 4 is supported on the rail located below it. In this case, the absorber of oscillations 2 is mounted on a base plate 9, for example being threaded therein, and the clamp 4 presses against this base plate 9.

Figure 6 shows a side view schematic at right angles to the rail of the layout of the oscillation absorber known from the utility model German DE 299 09 351 U1.

As can be seen from the figure 6, the clamp 4 is bent and extends open in a Y-shape, with both ends that are extended open pressing against the outer ends of the base plate 9, and with the oscillation absorber 2 arranged between these ends that extend open from the clamp 4.

This arrangement of the oscillation absorber known has the disadvantage that the clamp 4 may slip or break after it has been charged for a relatively long period of time.

The present invention, therefore, is based in order to provide a better disposition of the absorber of oscillations that can be installed and removed easily and that is more robust during operation.

Advantages of the invention

The idea on which the present invention is based is that the first clamping device is an angled plate with the first zone and the second zone at an angle to each other, and the first oscillation absorber can be installed in the second zone This means that there is no need for the base plate for the oscillation absorber, allowing achieve a compact and more robust structure, with the absorber of oscillations offering a very effective damping, since it is separated from the rail soul only by the second zone of the clamping device. The flat configuration of the device clamping improves robustness and prevents sliding towards above.

In addition, the disposition of the absorber of oscillations according to the invention and having the characteristics of Claim 1 can be easily installed and removed. Particularly when corrugated plates are used, all that is it is necessary to separate the fixing screw from the clamp support and hold the clamp under the clamp of support. The arrangement of the oscillation absorber according to the invention, in this case, can be manufactured at a lower cost as result of the use of corrugated plates, which are used normally in any case for mounting rails on wooden sleepers.

The use of this type of installation it also has the advantage that its fixation has already been used over a long period of time for railroads, and that the corresponding installation tools are generally available. The advantages mentioned above allow assembly faster. Tests have shown that new absorbers are they can install faster than known absorbers, Thanks to its compactness.

The strength of the clamping connection means that the lateral forces on the fixing screws are reduce. In conjunction with the tough wavy plate, this causes a much greater clamping force of the absorber on the rail. This further improves the effect of the absorber. Installation side of the absorber where it is possible to install the rail absorbers even if the separation of the sleepers It is very small.

Advantageous developments and improvements of the invention They can be found in the dependent claims.

According to a preferred embodiment, the first oscillation absorber can be screwed into the second zone of the side away from the soul of the rail.

According to another preferred development, the exterior of the nerves delimits the wavy plate in a U-shape, and its inside rests on the foot of the rail.

According to another preferred development, the first and the second support profiles are L-shaped, extending a L arm aligned with the outside of the nerves, and in which the other arm of the L can be pressed on the first zone.

According to another preferred embodiment, a second oscillation absorber can be installed on the underside of the wavy plate.

According to another preferred embodiment, the second oscillation absorber is narrower than the plate wavy

According to another preferred development, it is planned a second clamping device, which can be held in a first end between the other of the two support profiles and the foot of the rail, and that was placed so that, in a second extreme, it presses against the soul of the rail, and in which you can install a third oscillation absorber on the side of the second clamping device on the far side of the soul of the rail.

According to another preferred development, the first zone and the first support profile have a coupling device which counteracts the sliding of the first device of clamping, at least in the direction of the rail head. This greatly increases robustness.

According to another preferred embodiment, the device coupling has a bolt on the first support profile and a hole in the first zone, which can be coupled together.

According to another preferred embodiment, a nerve it has a cutout inside whose head can be inserted threaded bolt of a threaded bolt, whereby the first profile Support can be installed on one of the two nerves.

Description of the example embodiments

The identical reference symbols in the Figures indicate identical or functionally identical elements.

Figure 1 shows a side view schematic parallel to the rail of an embodiment of the arrangement of oscillation absorber according to the invention.

In figure 1, numerical reference 5 indicates a rail head, numerical reference 6 indicates a soul of the rail and numerical reference 7 indicates a foot of rail. An absorber of oscillations 1 is mounted with a snap fit below of the foot of rail 7, to dampen vertical oscillations, and it is screwed into a corrugated plate 8a from below by means of fixing screws 21a. The width of the absorber of oscillations 1 is designed so that it does not protrude beyond the ribs 10a of the corrugated plate 8 on the side.

The corrugated plate 8a has a section U-shaped transverse that is delimited by nerves 10a that surround the foot of rail 7, resting on it. The corrugated plate 8a is mounted on the foot of the rail by two L-shaped support profiles 3a. Support profiles in L-shape 3a are fixed to the corrugated plate 8a by a threaded nut 11 and a threaded bolt 12. An elastic washer 13 is located between the threaded nut 11 and the respective profile of L-shaped support

A clamping device 4a in the form of a plate that forms an angle is in each case held between the foot of the rail 7 and the respective support profile in the form of L 3a. Every angled plate 4a has a first flat trapezoidal zone 41 and a second flat rectangular area 42, with the first zone 41 being pressed against the foot of rail 7, and with the second zone 42 being pressed against the soul of the rail 6.

Oscillation absorbers 2 are coiled from the outside on the respective second zone 42, with fixing screws 20 ending in threaded holes 20a in zone 42.

Support profiles in the form of L 3a are extend from the outside aligned with the ribs 10a of the corrugated plate 8. This makes it possible to advantageously reduce the shear stresses that occur in the design shown in Figure 5, where the support profile 3 is U-shaped and is supported in a similar way on the outside of the nerves 10, on the corrugated plate 10.

To prevent the holding device 4 in shape of an angled plate slide up on the direction of the rail head, the angled plate has a hole 16 in which a bolt 15 is guided, which is provided in the L-shaped support profile 3a.

Direct installation of the absorbers of oscillations 2 by threaded bolts 20 on the plate in angle 4a allows a compact fit and damping of oscillations more effective than in the known case shown in the Figure 6, where the clamping device 4 was in the form of a Y-shaped clamp, where the ends of the Y are screwed to the base plate of an oscillation absorber.

In the design according to the embodiment, the oscillation absorbers 2 rest on the soul of rail 6 over virtually its entire length, and thus offer cushioning optimal

Figure 2 shows a side view schematic at right angles to the rail of the realization of the arrangement of the oscillation absorber according to the invention.

As can be seen in Figure 2, the nerve 10a of the wavy plate 8a has a cutout 19a in which a threaded bolt head 19 of the threaded bolt 12 is inserted, as result of which the support profile 3a can be installed easily on the wavy plate 8a.

Together, the realization of the provision of the oscillation absorber according to the invention offers a considerably greater compactness than known solutions previously. This is particularly advantageous for maintenance. of the rails and the bed of the track.

Figure 3 shows a schematic view in plant of the realization of the arrangement of the absorber of oscillations of the invention as shown in figures 1 and 2, compared to the two arrangements of the absorber of oscillations

In figure 3, reference A indicates schematically the arrangement of the oscillation absorber known as shown in Figure 4, in the mounting state. In this case, numerical references 21, 22, 23 indicate the fixing points In the oscillation absorber arrangement known, two 4 'clamping springs were required and fixed to points 21 and 22, as well as a threaded connection on the side opposite, corresponding to fixation point 23. In addition, the arrangement of the known oscillation absorber as shows figure 4 required a lot of space in the direction of the rail, since the base plate 8 'had to be of a length such that the two fixing points 21 and 22 are arranged about it.

In contrast to this, the arrangement of the oscillation absorber, indicated by reference N, according to DE 299 09 351 U1, as described previously, it can be placed in a transversal format with respect to to the rail. This is feasible because the clamp 4 is extends open, so that only one point of fixing 31 for anchoring the clamp 4. The additional fixing point 32 corresponds to the fixing point known 23. Therefore, it is possible with this arrangement to place two soul absorbers with only two fixing points. In addition, it is even possible to use more rail compartments narrow for the installation of the absorbers of oscillations

The oscillation absorber arrangement indicated with the reference N 'according to the described embodiment previously it can also be placed in a transversal format with respect to the rail, and consequently it is considerably more Narrow and more compact. This is because again only requires a fixing point 31 for anchoring the profile of clamping 3a for clamping plate 4a, and clamping profile 3a as well as the corrugated plate 8a are smaller than the clamp of clamping 4.

Together, the present invention produces a considerable simplification in terms of installation and accommodation of oscillation absorber arrangements for the rails.

Although the present invention has been described above with reference to a preferred embodiment of For example, it is not limited to it, but can be modified in many ways.

In particular, the clamps, the support clamps and oscillation absorber may have A different geometry.

Although in the previous embodiment the absorber of oscillations 2 protrudes slightly beyond the ends sides of the second zone 42 of the angled plate 4a in its extremes, of course, it is also possible that the absorber of oscillations 2 lean completely in position on this zone.

In addition, the first zone 41 of the angled plate 4a does not necessarily have to assume the trapezoidal shape represented, but may also have a rounded shape or A different polygonal shape.

Although in the previous example the device coupling has a bolt on the first support profile and a hole in the first zone, which can be coupled together, the invention is not restricted to this. Any elevated areas and recessed areas required on the clamping profile and the profile support are feasible as long as they can be coupled to each other to provide the desired robustness.
