Definitions

  • the invention relates to a switch for a switchgear track system for rail vehicles, the switch rail comprising rails carrying sleepers and a ballast bed supporting the sleepers and the bottoms of the sleepers facing the ballast bed being provided with elastic fillets and a central area of the switch, in which the rails are carried by continuous sleepers, and at least on one side of the switch there are two outgoing tracks, the rails of which are carried in sections adjoining the end of the switch by sleepers separate for each track.
  • a switch has two outgoing tracks, wherein a rail vehicle entering from the other switch end can be guided to a desired one of these two tracks by means of a tongue device, without interrupting the journey.
  • Points are points of failure of the track system at which the driving speed can only be relatively low.
  • the switches limit the performance of a rail network.
  • maintenance work on the bedding of sleepers which may be formed, for example in the form of a ballast bed, more expensive than in the field of a normal single track.
  • the sleepers For free tracks (ie off course turnouts), it is known to provide the sleepers with elastic fillets which, among other things, can reduce maintenance on the bedding supporting the sleepers. In the area of switches along which different, sometimes eccentric loads of the sleepers occur, the sleepers are conventionally laid directly on the bedding.
  • the object of the invention is to provide a switch of the type mentioned by which the load peaks acting on the ballast bed can be reduced. According to the invention, this is achieved by a switch with the features of claim 1.
  • the switch comprises at least two areas in which the stiffnesses of the fillets of the sleepers are different from one another.
  • the stiffnesses of the fillings are higher in at least one end region of the switch, preferably in both end regions of the switch, than in a central region of the switch, which comprises at least one frog.
  • the switch is in the form of a simple right turnout.
  • the switch thus has on one side an outgoing track 1 and on the other side two outgoing tracks 2, 3.
  • tracks 1, 2 as a single continuous track, this may also be referred to as a "trunk track” and the track 3 branching off from this as a "branch track”.
  • the rails 4, 5 of the switch are supported by sleepers 6, 7, 8 and are in this case connected to the sleepers 6, 7, 8 via fastening means 9, which in the Fig. 2 to 4 are indicated only schematically. Between the rails 4 of the two outgoing tracks 1, 2, 3 are intermediate rails. 5
  • a tongue device 10 which is also indicated only schematically, serves to selectively guide a rail vehicle entering the track 1 onto one of the tracks 2, 3.
  • the sleepers 6, 7, 8 are supported by a ballast bed 11 formed by ballast.
  • the illustrated simple turnout includes the following areas:
  • an end portion 12 of the switch is present at the end 22 of the switch over which the sleepers 6 have constant lengths l.
  • the lengths l preferably correspond to the lengths that the sleepers have in the free track following the switch (individual track).
  • the end portion 12 includes a central portion 13 of the switch.
  • This central area includes the overlap 14 of the rail tracks, wherein in the region of this overlap 14, the heart 15 of the switch is located.
  • the sleepers are designed as long sleepers 8 which have a greater length than the sleepers 6 of the end region 12, the length of the long sleepers 8 changing over the extent of the central region 13.
  • the length of the sleepers 8, starting from the side on which the individual track 1 lies increases to the side on which the two tracks 2, 3 are present.
  • the rails 4 of the outgoing tracks 2, 3 are in sections adjoining the end 18 of the switch for each track 2, 3 separate Sleepers 6, 7 worn. These sections of the rails 4 follow the last continuous long sill 8 of the central area 13 and over these sections extend the in Fig. 1 Plotted areas 16,17 of the switch.
  • the last continuous long sleeper 8 of the central area 13, which in Fig. 1 is visible at the right end of the central area 13 is also referred to as "last continuous threshold" or "LDS".
  • the rails 4 of each track 2, 3 are supported by separate sleepers 6, which are preferably all formed equal length and in this case, preferably, the length of the thresholds of the subsequent to the switch free tracks or individual tracks.
  • the Vorkopfnostin v ie the respective over the center of the rail 4 laterally projecting length of the threshold 7 (see. Fig. 4 ) at the mutually facing sides of the thresholds smaller than at the sides facing away from each other.
  • the tracks 2, 3 are thus arranged eccentrically to these thresholds 7. It comes thereby when crossing a rail vehicle to an asymmetrical distribution of the force acting on the threshold 7 force and thus to an asymmetric load of the ballast bed 11.
  • Such thresholds 7 are also referred to as "short-sleeper with one-sided shortened Vorkopfmother”.
  • the gravel bed 11 facing lower sides of all sleepers 6, 7, 8 of the switch are provided with elastic Besohlitch 19.
  • the fillets 19 comprise an elastic material in which the elastic portions at least predominate the plastic ones and which are formed in particular by an elastomer or a thermoplastic elastomer, wherein the fillets 19 preferably consist overall of an elastomer or thermoplastic elastomer.
  • Advantageous materials for the soles are, for example, polyurethane elastomers or rubber elastomers.
  • the rigidity in the longitudinal direction of the threshold 7 in the exemplary embodiment shown is made constant.
  • the average stiffness of the soles 19 on the other track 2, 3 closer half of the threshold 7 is greater than on the other of the other track 2, 3 further away half.
  • all the sleepers 7 in the region 16 have such fillings 19 whose stiffnesses change in the longitudinal direction of the sleepers 7.
  • this embodiment is preferred, it would also be conceivable and possible for only a portion of these sills 7 to be formed with such soles whose stiffness varies along the length of the sill 7, while the other sills are provided with solders 19, the stiffness thereof the entire length of the threshold 7 is constant.
  • the first threshold 7, which follows the last continuous long sleeper 8 of the central area 13 is provided with such a rigidity changing over the length of the threshold in its rigidity.
  • the switch further has also seen in the longitudinal extent of the tracks 1, 2, 3, at least two areas 12, 13, 16, 17, in which the solders 19 have different stiffnesses from each other,
  • the thresholds 6 in the at the ends 22nd , 18 of the turnout subsequent end regions 12, 17 are provided with fillets whose stiffnesses are greater than the stiffnesses of the fillets 19 in the central region 13 of the turnout.
  • the stiffnesses of the fillets in the end regions 12, 17 are the same for all sleepers 6.
  • the stiffness value here can correspond to the rigidity of the soles of the thresholds of the free tracks (single track) respectively adjacent to the tracks 1, 2, 3 of the switch.
  • two or more subregions may be formed in the central region 13, in which the stiffnesses of the fillets 19 of the long sills 8 are less than the stiffnesses of the fillets of the sills 6 of the end regions 12, 17, two or more subregions may be formed.
  • the solders of the long sills 8 could have smaller stiffnesses than in the one of the core 15 distant subarea.
  • the stiffnesses of the portions 20 of the fillets 19, which in the region of the ends of the sleepers 7 directed away from one another may be 2, 3, for example with the same stiffness as the long sleepers 8 in the region of the frog 15.
  • sections 21 of the soles, which in the areas the mutually facing ends of the sleepers 7 of the two tracks 2, 3, for example, the same stiffness values as in the adjoining the ends 22, 18 of the turnout end portions 12, 17 may be present.
  • a transition region could be present to achieve a more continuous transition of the stiffnesses of the fillets 19, the stiffness value in the transition region between that in the end region 17 and in the central area 13 or in the heart 15 comprehensive sub-area of the central area 13 could lie.
  • This transition region would thus comprise one or more sleepers 6 adjoining the region 16 in the direction of the end 18 of the switch, and the end region 17 would accordingly be shorter.
  • the transition region could itself be subdivided into two or more subregions to achieve an even more continuous course of rigidity.
  • the stiffness indicates what force is required for a particular depression in the material (or compression of the material).
  • the degree of rigidity is thus N / mm.
  • the stiffness of the sole 19 thus indicates how large the required force acting on the threshold 6, 7, 8 must be in order to achieve a certain lowering of the threshold.
  • the stiffness of the sole can be adjusted to a desired value by the hardness of the material used, from which the insole is made.
  • elastomers or thermoplastic elastomers of different hardness can be used.
  • PU elastomers are known in different degrees of hardness.
  • stiffness adjustments may also be made via the geometry of the sole, in particular by different thicknesses of the sole and / or different contact surfaces of the sole.
  • the support surface can be more or less reduced, for example, by grid-like arranged holes.
  • ballast stiffness along the track body Due to the design, there are differences in the ballast stiffness along the track body for switches with long pauses. These differences result from the continuously changing length of the sleepers and the components that act as stiffeners in some areas, such as the frog, the struts and the wing rails. Due to the varying load transfer thereby conventionally occurs at train crossing to different rail subsidence. These sinking differences can be at least reduced by different stiffnesses of the soles.
  • soles whose stiffness changes in the longitudinal direction of the threshold can also be used in a region other than in the described region 16.
  • the end portion 12 located on the side of the single track 1 could also be omitted, i. the length of the thresholds increases already starting from the end 22 of the switch on.
  • the invention is not limited to simple points.
  • the invention could also be used in a crossing switch (double switch), which has two outgoing tracks on both sides of the switch.
  • the central area of the switch would extend beyond any overlap of rail tracks and comprise at least two centers. The lengths of the long sleepers are reduced in this case from the ends of the central area to the center. Subsequent to the central area, the switch could in this case be formed on both sides in the manner described in the embodiment shown for the two outgoing tracks 2, 3.
  • the end regions 12 and / or 17 could also be omitted.
  • the material of the sole 19 could also extend over the side surfaces of the sills 6, 7, 8.
