Definitions
- the invention relates to a damping means for sound vibrations on rails, in particular bodies, made of plastic and iron materials, and a rail with corresponding damping means.
- a rail with damping means for damping sound vibrations is known from EP 0 150 264, in which the damping means is attached to the rail in a resilient or rigid manner.
- the damping agent consists of a solid body, a plastic layer and a metal sheet or a concrete body or a combination of all, the body being the rail between the addition of a permanently flowable intermediate layer, which consists of a liquid or a pasty or a jelly-like mass or a kneadable solid substance , the rail is coupled.
- the damping means can be coupled to the rail web on one side or on both sides by a resilient element, a tensioning bracket.
- Such damping means are to be used to dampen the sound vibrations generated by running over the rails in order to dampen the noise that is generated by these vibrations.
- EP document 0 150 264 is based on a state of the art according to the publication DE 1 784 171 A1, which describes rails which are glued to metal cover plates, with the interposition of plastics which do not undergo any notable changes in shape. These damping plates have a good sound-absorbing effect.
- a disadvantage is the gluing of the plastic to the rail web or the rail foot or the rail head, because welding work on rails is often required, which either produce the formation of toxic vapors of the outgassing products of the adhesive or loosen the adhesive again.
- DE 31 47 387 A1 in which it is proposed to press corresponding damping plates, that is to say metal sheets coated with plastic, onto the rail with the aid of springs.
- the desired damping effect which occurs due to the fact that there is a molecular shift in the plastic, which destroys the sound-emitting kinetic energy, can only have a partial effect because the coupling is insufficient and only selective.
- Glued rail A plastic that is made of a thermoset in the form of a two-component material based on a filled synthetic resin, such as polyester resins, polyurethane resins or ethoxylin resins, serves as an adhesive. It is found there that the hard plastic, unlike other plastics, such as rubber, passes through the sound
- Eliminate flexing work a significant improvement in noise damping testifies, since it is constrained by the gluing between the metal sheet and the rail web and is thus subjected to thrust.
- This type of damping means practically a doubling of the effectiveness compared to the conventional anti-drumming coatings that are only required by bending, although only very thin sheets with a thickness of less than one millimeter were used.
- EP 0 150 264 discloses a metal clip which engages around the rail foot and is approximately C-shaped overall and on both sides of the rail web metal sheets with a plastic layer on the web and the rail foot and the rail head couples, with appropriate shaping of the metal sheet and the plastic part.
- the EP document also discloses that one can use such damping means, vibration and sound absorbers, which operate in a known manner according to the absorber or reflection principle. It is also stated that the damping means can also be rigidly attached to the rail, parts of concrete and parts of steel being particularly easily connected in this way. This is based on the design of the damping agent, which can be additive to the metal sheet from a concrete body that is to be poured into a correspondingly shaped metal shell. Instead of the plastic and the metal sheet, a mold for concrete can be coupled to the rail, into which liquid concrete is then poured.
- a permanently flowable element such as an elastic foam soaked in a liquid or a gap filled with water or other pasty, jelly-like, kneadable substances as a permanently flowable mass between the concrete and / or the plastic-coated Metal sheet are arranged towards the rail.
- chamber fillers which are used everywhere in a tab or rail chamber as damping means and / or insulating means, that is to say as absorbers and / or reflection means, can be applied to the web or to the web with the aid of, for example, bitumen or other adhesive Rail head and / or the rail foot can be coupled.
- the invention is therefore based on the problem of proposing an improved solution for a damping means, in particular packing elements, for rails of a railway.
- a homogeneous body is coupled to the rail, which is produced separately by extrusion or injection molding in lengths of 200-2000 mm and essentially consists of a thermoplastic which is filled with metal components.
- the materials polyethylene or polypropylene have proven to be cheap as thermoplastics.
- a metal component is then introduced into the mold before extrusion or injection molding or pressing, preferably a pure ore made of hematite or magnetite or mixtures of the two in as small a granular form as possible, which carry out the extrusion or injection molding process do not hinder.
- Extrusion can take place.
- the metal components are completely enclosed by the thermoplastics, so that after the procedure completely homogeneous body with a plastic surface is present.
- the hematite components or magnetite components or mixtures of these will have a volume fraction on the body of 35-70%, which leads to a specific weight that the experiments of the inventors should be between 2.5-3.9 g / cm 3 , but preferably 2.9-3.5 g / cm 3 . This is a compromise in the amount of metal component parts to be added because of the good processability z.
- B In an extrusion machine with an appropriate shape that is tailored to the cross section of the tab chamber.
- a body manufactured in this way in particular a chamber filler essentially filling the chamber, having the cross-sectional dimensions of the link chamber of the rails can be attached to the web in a manner known per se from EP 0 150 264 A1 with the aid of a flowable intermediate layer and / or a metal clamp the rail and / or the rail head and / or the rail foot are coupled.
- Grooved rails are often used on road sections, while Vignol rails are mainly used on open sections. Accordingly, the tab chambers are designed differently and the fastenings are arranged on the substructure. Vignole rails are usually laid on sleepers, while tram tracks with grooved rails are often laid on longitudinal foundations using spacers, the tie rods.
- a chamber filler body may have to be designed differently, so that it is integrated into the fastening of the rail substructure or allows free space at these points in order to fix the fastening.
- Figure 1 shows a first embodiment of the invention
- Figure 2 shows a second embodiment of the invention.
- a rail 1 shown here in the top view has a rail head 2, a rail web 3 and a rail foot 4, between the rail head and rail foot there is a tab chamber or rail chamber along the rail web.
- FIG. 1 shows a damping means in the form of a chamber filler 5 that completely fills the chamber on both sides of the rail web 3.
- the chamber filler is coupled by means of an adhesive layer 6, which is shown here, as a gap between the rail head 2, the rail web 3 and the rail foot 4 and the chamber filler 5 in a completely filling manner.
- Adhesion or an adhesive gap can just as well only occur on the rail web or on the rail foot, because the rail web and rail foot are the parts of the rail which, due to their small dimensions, emit the most disturbing vibrations.
- the chamber filler is shown here so that the finely divided ores are visible, but the chamber filler is designed so that it feels like a plastic body, but has a very high weight and the metal parts, more precisely hematite or magnetite parts, neither can still be felt as such.
- a rail can be prepared, as is known per se, and can then be equipped with such a chamber filler body or at the factory.
- the person skilled in the art can also cover the chamber filler 5 with another plastic layer between the adhesive layer and the chamber filler if he wants to achieve a different setting of the softness of the surface.
- FIG. 2 shows chamber fillers 5 arranged in a manner similar to FIG. 1, but in this case they have a depression 51.
- a metal clamp 7 extends between the two depressions 51 and fixes the chamber filler 5 in its position on the rail web 3.
- This design can be used in addition to an adhesive layer 6 in order to increase the pressure of the chamber filler body on the rail web or to improve the coupling of the chamber filler body to the rail web 3.
- the chamber filler can also be provided with a
- brackets shown here Be plastic layer coated, which then fills the joint occupied by the adhesive here, especially if the rail has considerable rolling tolerances that slightly increase the coupling by positive locking.
- brackets shown here other bracket shapes can of course also be used.
- the chamber filler is manufactured in the lengths required on site; this can be longer distances of about 1m on a free route on a tram that does not have a rail foot attachment of the usual type, while otherwise the length of the chamber filler body to the
- Rail fastening is to be adjusted in length and shape.
