Definitions

  • the invention relates to a foot profile for the elastic mounting of rails, wherein the foot profile has a bearing surface for the rail and includes the rail foot on its outside and / or from its top.
  • Such foot profiles are used for rail insulation and thus to reduce vibrations, noise and stray current in track systems.
  • the profiles decouple the track from the adjacent superstructure and reduce vibration and vibration from rail traffic.
  • the rail foot is installed on a fußprofil remedyen, a kind of console-forming support surface. Beyond the bearing surface, the foot profile has arms on both sides which lie against the outer or top side of the rail foot and to a certain extent encase it.
  • Such profiles are z. B. from the EP 1 830 002 known.
  • These elastically mounted track systems are characterized, for example, by simple installation including track adjustment and gradient, the possibility of changing the rail without destroying the entire system, short locking breaks of the rail traffic, no tie rods or a non-existent shear in the surface.
  • the storage contributes to Streustromminimierung and to the reduction of structure-borne noise and thus to the protection of buildings and the local residents significantly.
  • Such profiles are disadvantageous in that they are poorly suited to absorb the forces occurring in rail traffic, in particular the lateral forces when cornering in a suitable manner. This is particularly problematic, taking into account the requirement that the horizontal deflection of the rail head must not exceed a prescribed level at this load.
  • the present invention has the object to provide a foot profile for the elastic mounting of rails, with the occurring transverse forces collected and the horizontal deflection of the rail head can be largely reduced.
  • This object is achieved in that the bearing surface of the foot profile to reduce the horizontal deflection of the rail head under load has an asymmetric stiffness.
  • the foot profile according to the invention is therefore particularly well suited for use in flat rail Vignolschienengleisen for trams, underground and S or full-course.
  • a preferred embodiment of the invention provides that the support surface has a stiffness that varies continuously from one side of the support surface to the other side in the manner of an asymmetrically running bracket, ie the course of the stiffness should be as linear as possible from one to the other side of the support surface . lose weight.
  • the bearing surface has a rigidity which changes continuously from one side of the bearing surface to the other side.
  • the goal of implementing an asymmetrical stiffness for the foot profile or its support surface can thus be achieved in a particularly suitable manner if the geometry of the foot profile or of the support surface changes from one side to the other.
  • the foot profile can be made entirely of one material, but considering the asymmetric geometry.
  • the support surface of the foot profile unevenly arranged and / or trained internals on the top of the support surface.
  • the bearing surface is therefore formed as solid as possible at the bottom, on its upper side are internals on which the rail supports.
  • the support surface is equipped with ribs of different widths.
  • the ribs are particularly large dimensioned in the direction of the other side of lower stiffness decreases their sizing.
  • the bearing surface can thus well withstand the lateral forces in the region of particularly strongly formed ribs or cushion them.
  • the support surface is equipped with ribs which have a different distance from each other. Ribs that are positioned particularly close to each other - in turn, in conjunction with correspondingly strong dimensions - thus in turn increase a particularly high rigidity of the foot profile in this area and thus to the property to represent a good suspension and absorb shear forces optimally. On the other hand, in the area of the inner side exposed to less transverse forces, it is sufficient if the ribs are dimensioned to be weaker or arranged at greater distances from one another.
  • the foot profile according to the invention is particularly well suited for use in railway technology, especially for trams, U and S or full tracks.
  • the support surface of the foot profile has a slope, which possibly contributes significantly in conjunction with the described design of the ribs in addition to reducing the rail head deflection.
  • the foot profile has an inclination of 1:20 to 1:60, preferably 1:40, so that at the same time a corresponding rail inclination is realized.
  • the total stiffness of the foot profile is about 50 to 100 KN / mm, based on a 1 m long track section.
  • the invention also relates to a rail mounted on an elastic foot profile, the foot profile having a bearing surface for the rail foot and comprising the rail foot on its outside and / or on its top side.
  • the foot profile for such a rail is to be regarded as advantageous in that the console-like support surface of the foot profile for reducing the horizontal deflection of the rail head under load has an asymmetric stiffness.
  • the invention is characterized in particular by the fact that a foot profile which is particularly flexible and can withstand the highest loads is provided for the elastic mounting especially of Vignole rails.
  • the rail is mounted on the console-like support surface of a foot profile, the z. B. thanks to their geometry is capable of recording high lateral forces without it could lead to a significant deflection of the rail head in the horizontal direction. This is achieved mainly by installations at the top of the bearing surface, on which the rail base supports. These ribs are continuously formed and / or arranged from one side of the support surface to the other, so that they contribute significantly to the described asymmetric stiffness of the entire foot profile.
  • FIG. 1 is a track bed 20 with a positioned on a threshold 19 rail pair 2, 2 'shown.
  • FIG. 2 represents a Vignolschiene 5, which is mounted on a foot profile 1 on the threshold 19.
  • This foot profile 1 is made of an elastic material, for. B. made of SBR as extruded article in variable lengths as a continuous or discontinuous profile.
  • the foot profile 1 has a positioned below the rail foot 4, console-like support surface 3.
  • the foot profile 1 surrounds the rail 4 on the outside 6 and is located on the top 7; the rail foot 4 is so to speak largely encased by the foot profile 1.
  • the support surface 3 is formed in the region of the substructure 17 as solid material, on its upper side 10 above there are ribs 11-16, which in the illustration according to FIG. 2 are arranged at different distances from each other, but have a uniform width.
  • the distances between the ribs 11-16 increase from the left side 8 to the right side 9, the smallest distance is, for example, the ribs 11 and 12 lying furthest on the left side 8.
  • the foot profile 1 so very stiff, about twice as stiff as on the right side 9, on the z. B. the two ribs 15 and 16 are located.
  • the contour of the support surface thus changes from the left side 8 to the right side 9 in that the stiffness decreases. Thanks to the good material properties and the optimal suspension in this area, the deflection of the rail head 5 in the horizontal direction under load in the direction of arrow 18 is significantly reduced.
  • the rail foot 4 is also covered by the fixation 27, 28 including the two spring elements 25, 26. In turn, the fixing elements 27, 28 are fastened on the threshold 19 via the fastening means 21, 22 with the springs 23, 24.
  • a Vignol rail 2 together with foot profile 1 shows FIG. 3 , here with much wider ribs 11-16, whose distance also increases continuously from the left side 8 to the right side 9, so that the rigidity on the side 8 is significantly higher than on the side 9, which is characterized by a reduced deflection of Rail head 5 when loaded in the direction of arrow 18 makes noticeable.
  • the foot profile 1 serves as a support for rail 2 or Rail foot 4 and the sheathing of the rail foot 4 on the outside 6 and in the region of the arms 29, 30 on the upper side 7 of the rail foot 4th
  • FIG. 4 Well illustrated is that the bearing surface 3 has a tendency from home, symbolized by the not parallel to the baseline 31 extending inclination line 32, which possibly in conjunction with the Training and / or arrangement of the ribs 11 - 16 leads to the advantageous asymmetrical design of the foot profile 1 or bearing surface 3.
