  • the base plate 212 is placed like a rib plate as a kind of load-bearing and distribution plate.
  • the rail is fastened via the base plate 212 either with a screwed clamping element, such as a clamping clamp, hook screw, nut and washer, or by means of an inserted clamping element, such as an e-clip or fast clip.
  • the vertical relative movement of 1 to 4 mm of the base plate 212 to the guide pieces 222, 224 or to the threshold 220 is predetermined in accordance with the spring stiffness of the elastic intermediate plate 214.
  • a thin base plate 218 made of EVA serves as a leveling surface for unevenness on the top of the threshold and at the same time as an electrical insulator between the electrically conductive components and the concrete sleeper.
  • the two guide pieces 222, 224 fix the movements of the primary elements of the elastic bearing such as ribbed plate bearing, consisting of base plate 212 and elastic intermediate plate 214, in a form-fitting manner in the longitudinal and lateral directions.
  • the vertical movement of the base plate 212 is made possible as a result of a lowering of the elastic intermediate plate 214 resulting from the wheel load.
  • the base plate 212 and the elastic intermediate plate 214 have no through holes for fixing and bracing against the concrete sleeper 220.
  • the guide pieces 222, 224 have pockets (receptacles) for the positive locking of the base plate 212 and the elastic intermediate plate 214. The movements of the base plate 212 in the horizontal plane are blocked within these pockets.
  • Each e.g. 1 mm high elevations on the rear wall and on the side flanks within the pocket are intended to reduce the contact friction of the base plate with the guide piece during the vertical depression.
  • the guide piece 222, 224 has reinforced ribs on the flanks, so that it can absorb the wheel guiding forces that are transmitted through the base plate 212, as well as the forces and moments that arise when the elastic intermediate plate 214 is tensioned, without overstressing.
  • elastomer spring 258, 260 is used as the upper spring.
  • the cuboidal elastomer spring made of vulcanized chloroprene rubber has two small pins 282, 284 which are circular in cross section on the top side.
  • Equivalent blind holes 274, 276 in the guide piece 222, 224 serve for the positive reception of the elastomer spring 258, 260.
  • the elastomer spring 258, 260 connected in series with the elastic intermediate plate 214 is intended to reduce the resulting overall spring rate when the guide pieces 222, 224 are tensioned and to ensure continuous conditions over all stiffnesses of the elastic intermediate plates 214.
  • the elastomer spring 258, 260 has a spring rate of approx. 450 kN / mm. Ideally, the elastomer spring 258 260 is compressed by 3 mm when the guide pieces 222, 224 are braced. The base plate 212 is thus preloaded with approximately 1.3 kN per side.
  • the unstressed elastomer spring 258, 260 is dimensioned so high that in the tensioned state over all component tolerances of guide piece 222, 224, Base plate 212 and elastic intermediate plate 214 always make contact with the base plate 212.
  • the base plate 212 has the task of absorbing the wheel loads acting vertically and horizontally via the rail and subsequently distributing them over a large area to the base element below. Furthermore, the base plate 212 serves to anchor optionally screwed or plugged rail fastening elements. For this purpose, the base plate 212 can either have pairs of rib cams, for fastening with KS superstructure, or shoulders corresponding to the respective type, for fastening with inserted tensioning elements, on both sides of the rail.
  • the elastic intermediate plate 214 consists only of a full-surface spring element.
  • the different stiffnesses are realized by different recipes of the closed cell polyether urethane.
  • the defined plate thickness can e.g. 12.5 mm.
  • the guide pieces 222, 224 are fixed to the threshold 220 with four threshold screw axes each.
  • the threshold screws can have a trapezoidal thread.
  • a polymer dowel with a steel shell is placed in threshold 220.
  • a spring ring inserted above the guide piece 222, 224 can generate a pretensioning force of approx. 30 kN for each axis.
  • the resulting frictional connection between the guide piece 222, 224 and the cast-in dowel in the concrete sleeper 220 has the effect that the positively integrated base plate 212 is held in position in the horizontal plane.
  • shear stress on the screws is avoided. This means that the acting wheel guiding force is reduced by the bolt preload and the frictional force between the braced plates due to the proportion of the vertical wheel load.
