Definitions

  • the invention relates to a double crossing threshold, as described in the preamble of claim 1.
  • Thresholds for gravel superstructure in railways are already known from the prior art, which run below and across the laid rails and record them on supports. Such thresholds make it possible to absorb the longitudinal and transverse forces arising when rolling over a rail vehicle and to dissipate them into the ballast so that a track geometry, in particular the track spacing defined by the wheelbase of the rail vehicles, can be maintained for a stable track position. Due to increasing stresses on the thresholds, e.g. caused by increased transport loads, speeds and braking forces of rail vehicles and narrower curve radii of the track tracks, it is necessary to better absorb the resulting forces and dissipate into the substructure or gravel, this being cost-effectively manufactured and at the same time operationally safe thresholds are required.
  • the threshold described in this document is provided with transverse arms extending below the rails, the undersides of which lie in a plane with the threshold underside.
  • This cross arms thus results in an overall enlarged contact surface of the threshold on the ballast or the substructure, so that a sinking of the threshold is made difficult in the ballast and stabilization of the threshold against tilting about its longitudinal axis.
  • the rails rest on bearings which are mounted on the upper side of the transverse arms, and the rails are each positioned at least in the transverse direction to the rail by two rail fasteners provided laterally of the bearing.
  • the disadvantage is according to the DE 100 23 389 A1 in that only two rail fastenings are provided per rail support, which are provided in the region of a threshold longitudinal axis.
  • the two rail fasteners can the high displacement forces the tracks may not be sufficiently resisted, so that increased track dislocations above a normal level create a safety hazard from possible damage to the track.
  • the problem of increased rail displacement forces particularly occurs with rail vehicles with eddy current brakes, as they are increasingly used.
  • frame sleepers are known, which are formed by two extending between the rails sleepers, which are connected in the region of the rail track below the rails via a side rail to form a component.
  • a frame threshold is from the DE 102 54 973.7 known.
  • Each of the rails is located on each of a top of the thresholds, so that the frame threshold has four supports, with rail fasteners attached to each support at installation positions.
  • There are three mounting positions “outside”, “centered”, “inside” are provided, which are each formed by a pair of opposing rail fasteners.
  • the attachment points are variable by pairing rail fastening elements.
  • Such frame thresholds have the disadvantage that due to the four supports for the rail elements, the entire frame threshold is considered to be statically indeterminate, so that in their production a very high dimensional accuracy is required to allow an equal altitude of the four supports while maintaining small dimensional tolerances, as it even with small deviations may lead to a break of the threshold. To prevent this, it is necessary to produce the frame threshold in special or complex manufacturing processes.
  • thresholds with transverse arms although an improvement in operating characteristics by an increased bearing surface on the ballast and a cost-effective production allow, but at elevated load, a sufficient resistance to track distortions can be applied.
  • frame thresholds by varying the mounting positions of the rail fasteners, the resistance, which is opposed to the track distortions to adapt to different load cases, with frame thresholds, a high production cost is necessary and the maintenance costs are much higher compared to simple thresholds.
  • a variable positioning of the rail fasteners on simple sleepers, such as in the DE 100 23 389 A1 described previously was not possible in the prior art due to the inappropriate geometry of the transverse arms or rail carrier.
  • each threshold element comprises a pad of elastic material to achieve a vertical deflection.
  • the flexurally soft, but rigid connection of successive longitudinal beams is formed by sufficiently flexurally elastic rails themselves, and the rail fastening points are each initially provided to the respective mutually facing edges of the threshold elements, so that there are two fastening points per longitudinal beam.
  • Object of the present invention is to provide a threshold for a ballast track in railways, which allows the installation of a connecting element for connecting two consecutive rail elements in the installed state.
  • the object of the invention is achieved by the features stated in the characterizing part of claim 1.
  • the advantage is achieved that is created by the stepped in the region of the end faces below the rail members longitudinal beams during assembly of the rail track between the rail base and an upper step surface a gap.
  • the recording and derivation of the generated rail, transverse or longitudinal displacement forces is improved because between the nearest rail fasteners of two adjacent thresholds not the Threshold distance between two laid sleepers must be complied with, but seen in the rail running direction shorter mounting distances between the rail fasteners can be met.
  • the fastening or clamping points on which the rail fastening elements fix the corresponding rail element can thus be distributed uniformly or non-uniformly along the rail path, depending on the load situation, and the sections along the rail track in which no rail fastening elements are provided can be strong be shortened. In general, therefore, the rail layer or the entire track body can be stabilized.
  • the features of claim 5 are advantageous because a total of six or four rail fasteners can be attached to each side rail of the sleeper by the three or two receptacles on each side of the support.
  • the threshold can therefore, depending on the number of arranged on this rail fasteners to different applications, such as straight lines, Curved radii, mountain ranges, routes with high transport loads or the like., To be adjusted.
  • the threshold can be adjusted in an advantageous manner individually to the respective load cases by activating or deactivating the recording devices.
  • the arrangement of the rail fastening elements can thus be made at a construction site when laying a track section, with a variable arrangement of the rail fastening elements is made possible.
  • the threshold can be prepared for the track with normal or medium load by the arrangement of two rail fasteners, which are preferably opposite diagonally.
  • this first mounting position there is a continuous distribution of rail fastening elements along the rail track, wherein a mounting distance between two nearest rail fasteners of two adjacent thresholds may be less than the threshold distance.
  • an embodiment of the threshold according to claim 15 is advantageous, since a total of four rail fasteners per longitudinal beam are arranged in a third mounting position, whereby the threshold can also be used for track tracks with very high loads.
  • the generated longitudinal or transverse forces can be taken individually adapted by the two side members, i. depending on the load occurring, the acting transverse drag resistance on the individual rail elements can be determined individually by a corresponding number of rail fastening elements or corresponding distribution of the rail fastening elements, so that a stable position of the mutually parallel rail elements is ensured.
