Definitions

  • Switches represent crossing points in track systems, where at least one branch track is introduced into or led out of a main track. There are so-called simple points where a branch track is led out of or into a main track. However, there are also so-called crossing switches, where a branch track crosses a main track and leads out over this on both sides.
  • the AT 503 772 B1 shows a switch in which sleeper pads with at least one elastomer layer are arranged on the sleeper undersides of the sleepers. Between the rails and the sleepers are located in the AT 503 772 B1 Intermediate layers, which are referred to in this document as fasteners. From the AT 503 772 B1 it is also known to vary the softness or hardness of the sleeper pad over the length of the sleeper.
  • the FR 2 410 086 A1 shows generic prior art.
  • an elastic intermediate layer is provided between the rail and the sleeper and an elastic sleeper sole is provided under the sleeper.
  • the object of the invention is to counteract tilting of the sleeper at specific points in the switch.
  • An elastic level is thereby at least one Elastomer layer of the sleeper soles formed.
  • a second elastic level is formed by the elastomer layers of the intermediate layers. The elastic properties of these elastomer layers can be matched to each other depending on the requirements, in order to achieve a matched optimization by means of both elastic levels.
  • the insulation properties of the overall system of the switch can be very precisely adapted to the different requirements occurring in the switch at different locations.
  • the deflection can be homogenized over the course of the switch.
  • the addition of at least one second elastic level allows the elastic properties of the switch to be fine-tuned to the specific tasks to be solved locally within the switch at various points.
  • both the sleeper pads and the intermediate layers can each be constructed in one or more parts.
  • Both the sleeper pads and the intermediate layers can each consist of a single layer of elastomer. However, they can each also have several elastomer layers.
  • the sleeper soles as well as the intermediate layers can also have non-elastic components or layers. In the sleeper soles, it can be, for example, as from the AT 506 772 B1 known multi-layer structure with two elastic layers, a reinforcement layer and a random fiber or connecting layer act.
  • the intermediate layers can also have metal plates, for example, as is also explained below by way of example in the description of the figures.
  • Preferred variants of the invention provide that in the switch the elastomer layers of at least two different sleeper pads have a different bedding modulus and/or that in the switch the elastomer layers of at least two different intermediate layers have a have different stiffness from each other.
  • the bedding moduli of the elastomer layers of the at least two different sleeper pads differ from one another by an amount of at least 25% of the larger bedding modulus and/or that the stiffness of the elastomer layers of the at least two different intermediate layers by an amount of at least 25% of greater rigidity differ from each other.
  • the sleeper soles have areas of different hardness or softness along the longitudinal direction of the sleeper.
  • the elastomer layers are, as this term suggests, layers of at least one elastomer.
  • Elastomers are dimensionally stable but elastically deformable plastics that deform elastically under tensile and compressive loads, but then at least essentially return to their original, undeformed shape. Provision is particularly preferably made for the elastomer layer of the respective intermediate layer and/or the elastomer layer of the respective sleeper sole to have polyurethane or rubber or a mixture with polyurethane and/or rubber.
  • the elastomer layers mentioned can also consist entirely of the materials mentioned. Rubber can be natural but also synthetic rubber elastomers. It is preferably foamed polyurethane and/or foamed rubber. Both foamed variants are preferably designed with closed pores.
  • the elastomer layer of the respective sleeper sole to have a bedding modulus in the range from 0.02 N/mm3 (Newton per cubic millimeter) to 0.6 N/mm3, preferably from 0.1 N/mm3 to 0.5 N/mm3, particularly preferably from 0.15 N/mm3 to 0.4 N/mm3.
  • the bedding modulus is often used to describe the deformation behavior in ballasted track. It describes the relationship between surface pressure and the associated depression. A softer material therefore has a lower bedding modulus and vice versa. In simplified terms, the bedding modulus indicates the surface pressure at which a certain depression occurs.
  • the elastomer layer of the respective intermediate layer is favorably stiff in the range from 5 kN/mm (kilonewtons per millimeter) to 1,000 kN/mm, preferably from 10 kN/mm to 300 kN/mm, particularly preferably from 20 kN/mm to 200 kN /mm, provided. Stiffness could also be referred to as spring index or support point stiffness. It describes the relationship between the base force and the deflection. With softer materials, the rigidity is lower than with relatively harder materials.
  • the bedding modulus can be determined, for example, according to DIN 45673, August 2010 edition. Stiffness can be determined according to EN 13146, April 2012 edition.
  • the elastomer layer of the sleeper sole of each of the sleepers has at least two differently soft areas, the harder region of the elastomer layer of the sleeper sole under a first of the rails and the softer region of the elastomer layer of the sleeper sole is arranged under a second of the rails, the first of the rails and the second of the rails being spaced apart from one another and being fastened to the upper side of the sleeper of the respective sleeper and the elastomer layer of the intermediate layer arranged between the first of the rails and the upper side of the sleeper of this sleeper and the elastomer layer of the intermediate layer arranged between the second of the rails and the upper side of the sleeper of this sleeper differ in softness relative to one another.
  • the elastomer layers of the intermediate layers above the sleeper i.e. on the top side of the sleeper on the longitudinal
  • the points that are spaced apart from each other on the threshold are designed with different degrees of hardness or softness. Provision is particularly preferably made for an intermediate layer with a relatively soft elastomer layer to be located in the area above a relatively soft area of the elastomer layer of the sleeper sole, and vice versa.
  • the elastomer layer of the intermediate layer arranged between the first of the rails and the upper side of the sleeper of this sleeper is harder than the elastomer layer of the intermediate layer arranged between the second of the rails and the upper side of the sleeper of this sleeper.
  • This variation of the hardness or softness both in the intermediate layer and in the sleeper base along the longitudinal direction of the sleeper an improved and more homogeneous load transfer can be achieved in a particularly finely tuned manner, in order to counteract tilting of the sleepers.
  • the invention is particularly preferably used in the case of short sleepers adjoining the last continuous sleeper, but also in the so-called frog area of the points.
  • the elastomer layers of the sleeper soles of at least two of the sleepers arranged one after the other have different softness relative to one another and also the elastomer layers of the intermediate layers on at least two of the sleepers arranged one after the other are made differently soft relative to one another, with the elastomer layers of the intermediate layers on these two sleepers being equally soft in the event of a change in the softness of the elastomer layer of the sleeper sole from one of the sleepers to the next longitudinal sleeper and/or in the event of a change in softness the elastomer layer of the intermediate layer from one of the sleepers to the following sleeper in the longitudinal direction the elastomer layers
  • this application of the basic principle mentioned means that changes in the softness in the plane of the sleeper padding are not accompanied at the same time by changes in the softness in the plane of the intermediate layers, but these changes are offset in the longitudinal direction transverse to the sleepers by at least one sleeper relative to one another are. As a result, the changes in the elastic properties along the switch can be smoothed out or smeared.
  • This principle is advantageously used in the entire turnout area. An overlap over several thresholds is favorable. According to this variant of the basic principle mentioned, it is therefore provided that changes in the softness or hardness in the plane of the intermediate layers are always arranged offset to changes in the softness or hardness in the plane of the sleeper pad.
  • ballast bed is usually relatively thin, ie with a relatively small vertical extension and, in addition, the sleepers are designed to be relatively short.
  • this area of the rail in particular, there is a build-up of forces due to the temperature-related expansion and contraction of the rails, but also due to point heaters that are often arranged there. Both together lead to a tendency for the tracks to buckle horizontally at the side.
  • the sleeper pad should be designed to be relatively plastic or tough-elastic in the area of the tongue device in order to achieve the highest possible resistance to lateral displacement in the ballast bed or on another base.
  • the relatively soft elastomer layer in the intermediate layer can thus be used to compensate for a relatively hard elastomer layer in the sleeper sole to ensure the required transverse displacement resistance, so that the overall desired elastic behavior results in the vertical direction.
  • the elastomer layers of the sleeper sole are viscoelastic with an EPM index in a range from 10% to 25%, preferably from 10% to 20%, with the EPM index like in the WO 2016/077852 A1 is defined and can be measured.
  • the elastomer layers of the intermediate layers have a stiffness in a range from 20 kN/mm to 200 kN/mm, preferably from 40 kN/mm to 100 kN/mm.
  • the preferred relationships and properties specified in patent claims 5 to 8 can each apply to the at least one elastomer layer of the sleeper sole and/or the at least one elastomer layer the intermediate layer, but also apply to the entire sleeper base and/or the entire intermediate layer.

  • the structure of switch 1 described so far 1 is known per se and therefore does not need to be explained further.
  • rail 2 basically includes all types of rails 2, regardless of whether they are specifically designated and additionally provided with their own reference sign or not.
  • FIG. 2 to 7 each is a schematic representation of vertical sections along the above-mentioned cutting lines. It is shown how in the corresponding sections the respective rails 2 rest by means of the intermediate layers 6 on the sleeper tops 5 of the sleepers 4 and how the sleepers 4 rest on a ballast bed 28 via the sleeper soles 8 arranged on their sleeper undersides 7 .
  • the way in which the rails 2 and the intermediate layers 6 are fastened to the sleepers 4 is not shown in the illustrations. It can be designed as in the prior art. The same applies to the attachment of the sleeper soles 8 to the sleeper undersides 7 of the sleepers 4.
  • the sleeper soles 8 can be arranged not only on the underside 7 of the sleeper, but also on the side surfaces of the respective sleeper 4, preferably projecting a little upwards.
  • the sleeper soles 8 can also be referred to as sleeper shoes become. These can also have sleeper shoe insert plates that are known per se.
  • both the intermediate layers 6 and the sleeper soles 8 are shown as single-layer bodies in the form of the elastomer layers 10 and 9, respectively. As explained above, this does not have to be the case.

  • the elastomer layers 9 of the sleeper soles 8 and also the elastomer layers 10 of the intermediate layers 6 have been hatched differently.
  • Each type of hatching is an example of a certain degree of hardness or softness of the respective elastomer layer 9 or 10, with the representation chosen being purely about the relationships relative to one another.

  • the elasticity or softness of the elastomer layer 9 of the sleeper sole 8 is constant over the entire longitudinal extent in the longitudinal direction 31 of the sleeper 4 .
  • the elastomer layers 10 of the intermediate layers 6 arranged on the sleeper top 5 are harder than the elastomer layer 9 of the sleeper bottom 8, but are designed to be equally soft or hard relative to one another.

  • the sleeper 4 shows the vertical section in the frog area 16 of the switch 1 along the section line CC Fig.1 and thus along a sleeper 4 designed as a long sleeper, which is always loaded eccentrically when a train passes over it, since the train runs either along the main track 3 or along the branch track 18 .

  • This is a vertical section along line DD 1 , i.e. a vertical section of the short sleeper 21 immediately following the last continuous sleeper 20.
  • These short sleepers 21 tend to tilt, since they protrude less far beyond the rail 2 on one side than on the opposite side due to the limited space required on one side.
