Definitions

  • the invention relates to a rail with damping means using a Kammer hypolligens.
  • the font EP-A-0 404 756 discloses a ballastless superstructure, with rails for rail-bound traffic, which are detachably connected to carriers, which have at least two rails, each on either side of the rail web, optionally up to the rail head and optionally to the rail foot reaching Schalldämpf issued abutting the rail and the sound damping device is formed with a coating which is adhesively held on the rail, at least substantially completely covers the rail web and rail foot and the coating comprises particles bound with a binder, in particular with a grain size of 2 mm to 8 mm and optionally with fibers, z. As glass fibers, is constructed.
  • the coating consists of particles bound with a binder, such as crushed stone, split, or the like
  • a further inhibition of the sound conduction is already predetermined in the coating, since the particles and the binder conduct the sound differently, so that they adhere to the respective interfaces Reflections of the sound waves comes, whereby the delivery of sound to the air and thus the annoyance by sound can be substantially reduced.
  • the damping means consists of a solid body, a plastic layer and a metal sheet or a concrete body or a combination of anything, wherein the body is the rail between joining a flowable intermediate layer, which consists of a liquid or pasty or a jelly-like mass or a kneadable solid material which is coupled to rail.
  • the damping means by a resilient Element, a clamping bracket on one or both sides coupled to the rail web.
  • Such damping means should be used to dampen the sound vibrations generated by passing over the rails to dampen the noise caused by these vibrations.
  • the EP document 0 150 264 is based on a prior art according to the document DE 1 784 171 A1 which describes rails that are glued to metal cover sheets, with the interposition of no appreciable changes in shape suffering plastics. These damping plates have a good sound-absorbing effect.
  • a disadvantage is the bonding of the plastic to the rail web or the rail or the rail head, because often welding work on rails are required to produce either the emergence of toxic fumes of the gassing of the adhesive or loosen the bond again.
  • the EP document also refers to a German patent application DE 31 47 387 A1 Reference is made, is proposed in the corresponding damping plates, so coated with plastic metal sheets, with the aid of springs to the rail.
  • the desired damping effect which occurs by the fact that there is a molecular shift in the plastic, whereby the sound-emitting kinetic energy is destroyed, can therefore only partially affect, because the coupling is not sufficient and only selectively.
  • a plastic composed of a thermosetting resin in the form of a 2-component material based on a filled synthetic resin, such as polyester resins, polyurethane resins or ethoxyline resins serves as an adhesive. It is found there that the hard plastic, unlike other plastics, such as rubber, which destroy the sound by flexing, a significant improvement in the noise attenuation testifies, since he is constrained by the bond between the metal sheet and the rail bridge and so on Shear is claimed. This type of damping means virtually over the conventional, by bending claimed Entdröhnungsbervers Doubling of effectiveness, although only very thin sheets with thicknesses of less than one millimeter were used.
  • the EP document further discloses that it is possible to use such damping means, vibration and sound absorbers, which operate in a known manner according to the absorber or reflection principle. It is further stated that the damping means could also be rigidly attached to the rail, in which way parts of concrete and parts made of steel could be coupled particularly easily. This is due to the formation of the damping means, which could be additive to the metal sheet of a concrete body, which is to be poured liquid 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 flowable element such as a liquid-soaked elastic foam or a water-filled gap or other pasty, jelly-like, kneadable substances as a flowable mass between the concrete and / or the plastic-coated Sheet metal are arranged towards the rail.
  • Kammer hypoxia that find everywhere in a tab or rail chamber as a damping means and / or insulation, so as absorber and / or reflection means application, for example, bitumen or other adhesive to the web or on the Rail head and / or the rail foot can be coupled.
  • the invention is based on the problem to propose an improved solution for rails of a railway with damping means.
  • the plastic is to be subjected to shear, so that by frictional energy, the vibration energy is absorbed in the rails.
  • this is possible only with the help of the metal sheet or the coupled concrete masses whose inertia is utilized relative to the faster vibrated plastic.
  • a homogeneous body is coupled to the rail according to the invention, which is produced by extrusion or injection molding in lengths of 200 - 2000 mm separately and consists essentially of a thermoplastic, which is filled with metal components.
  • thermoplastics the substances polyethylene or polypropylene have been found to be favorable.
  • a metal component is then introduced into a mold before extrusion or injection molding or pressing, preferably a pure ore of hematite or magnetite or mixtures of the two in the smallest possible granular form, the extrusion or injection molding process do not hinder.
  • the metal components are completely enclosed by the thermoplastics, so that after the process a completely homogeneous body with a plastic surface is present.
  • the hematite portions or magnetite portions or mixtures of these will have a volume fraction of the body of 35-70%, which leads to a specific weight after
  • the attempts of the inventor 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 components to be added because of the good processability e.g. B. in an extrusion machine with a corresponding shape, which is tailored to the cross section of the tab chamber.
  • a body produced in this way in particular a chamber filling body substantially filling the chamber with the cross-sectional dimensions of the tab chamber of the rails in the from the EP 0 150 264 A1 known manner with the aid of a flowable intermediate layer and / or a metal clip to the web of the rail and / or the rail head and / or the rail foot can be coupled.
  • Grooved rails are often used on road sections, while Vignol rails are used on the open road. Accordingly, the tab chambers are designed differently and arranged the fasteners on the substructure.
  • Vignole rails are usually laid on sleepers, while tram tracks with grooved rails are often laid with spacers, the tie rods, on longitudinal foundations. Accordingly, a Kammerhellmaschine must optionally be designed differently, so that it is integrated into the attachment of the rail substructure or granted at these points a space to fix the attachment.
  • a rail 1 shown here in a top view, has a rail head 2, a rail web 3 and a rail foot 4, between the rail head and rail foot results along the rail web a tab chamber or rail chamber.
  • FIG. 1 is a damping means in the form of a chamber fully filling chamber filler 5 shown on both sides of the rail web 3.
  • the chamber filling body is coupled by means of an adhesive layer 6, which is shown here, as a gap between the rail head 2, rail web 3 and rail 4 and 4 Grillfeldll stresses full filling.
  • an adhesion or an adhesive gap can only occur on the rail web or on the rail, because rail web and rail, which are parts of the rail, which emit the most disturbing vibrations due to their small size.
  • the Kammer spall analyses is shown here so that the finely divided ores are visible, however, the Kammer spallianu is designed so that it feels to the outside, as a plastic body, but has a very high weight and the metal parts, more precisely Hämatit- or Magnetitmaschine neither tangibly still recognizable as such.
  • a rail can be as well known, prepared and so then or already factory equipped with such a chamber filler.
  • the person skilled in the art can also cover the chamber filling body 5 with another layer of plastic between the adhesive layer and the chamber filling body if he wishes to achieve a different setting of the softness of the surface.
  • FIG. 2 shows in a similar way as FIG. 1 arranged chamber filling 5, but in this case have a recess 51. Between the two recesses 51, a metal bracket 7, which fix the Kammer Stahlllianu 5 in position on the rail web 3 extends.
  • This construction can be used in addition to an adhesive layer 6 in order to increase the pressure of the Kammer Stahlll stressess on the rail web, or to improve the coupling of the Kammer Stahlll stressess to the rail web 3.
  • it may also be coated instead of an adhesive layer 6 of the chamber filler with a plastic layer, which then fills the here occupied by the adhesive joint, especially if the rail has significant rolling tolerances that increase the coupling by positive engagement slightly.
  • brackets shown here of course, other types of brackets can be used.
  • the Kammer hypoxia is made in the necessary local lengths; this can be greater distances of about 1 m in the open road in a tram that has no rail foot mounting of the usual type, while otherwise the length of the chamber filler is to be adapted to the rail fastening in its length and shape.
