Definitions

  • the invention relates to a laminated spring, in particular for rail vehicles, with an inner and an outer connector part and at least two spring layers therebetween alternately an elastomer layer and a sheet metal layer, wherein the E- lastomerlagen are vulcanized together with the connecting parts and the sheet metal layers together and the elastomer layers of Spring layers have mutually different thicknesses, each elastomer layer is made of the same material.
  • Such laminated springs are also called primary springs because they are often the primary spring stage, i. form the spring stage between the wheel and the bogie in rail vehicles.
  • the layer springs can have different shapes.
  • the individual spring layers can be arranged cylindrical or conically concentric with each other.
  • the invention has for its object to provide a laminated spring of the type described above, which has an improved, continuous spring characteristic while avoiding the disadvantages mentioned.
  • the layer spring has a substantially conically contoured support plate, which is arranged in the loading direction above the thickest spring layer and corresponds to the different thickness spring layers in such a way that initially the inner part of the softest layer on the supporting expensive supports and with increasing load, the outer parts of the softest layer and the other spring layers are continuously increasingly supported on the support plate.
  • the support plate causes a steady spring characteristic, since at low load only the inner soft spring layer of the laminated spring springs through this construction and at higher loads, the further spring layers increasingly participate increasingly in the deflection. By the support plate overloading of the thickest softest spring layer is avoided.
  • the characteristic curve can be adapted to the application, for example as a continuously progressive characteristic curve.
  • the elastomer layer of the inner spring layer is thicker by a factor of three than the elastomer layers of the remaining spring layers.
  • the inner spring layer is considerably softer than the other spring layers.
  • the hardness of such a spring layer is determined not only by the hardness of the material but also by the geometry of the layer, the geometry influence being determined by the shape factor F.
  • the form factor F describes the ratio of free to bonded elastomer surface of an elastomer layer. If the free surface of an elastomer layer becomes larger with a constant, permanently vulcanized, ie bonded area, the form factor increases. Large values of F described a soft, small value of F a hard spring property.
  • Such a laminated spring can be adapted in the erf ⁇ ndungshiele way with continuous characteristic to different applications and manages without elaborate manufacturing methods, since for example by omitting one or more sheet metal layers, the freely deformable elastomer surface of the resulting thicker Elas- tomerlage is easily enlarged , The use of different materials is not required.
  • the single FIGURE shows a laminated spring 1 in installation position without load in longitudinal section, wherein an inner connector part 2 with a connecting pin 3 facing upwards and carries a load, not shown here.
  • the layer spring 1 has an outer connection part 4 and a number of conical, concentrically arranged sheet metal liners 5, 6, 7 and 8 with mean diameters which increase toward the outside.
  • sheet metal liners 5-8 conical elastomer layers 9, 10, 1 1 and 12 are respectively arranged, with their respective facing the main axis 13 of the laminated spring 1 or repellent from the main axis 13 surfaces fixed to the respective surfaces of inner connector part 2, the Sheet metal liners 5 - 8 or the outer terminal part 4 are vulcanized.
  • the sheet metal liners 5-8 and the elastomer layers 9-12 are arranged relative to one another such that the layer spring 1 has an upwardly tapering frustoconical shape.
  • a support plate 14 is fixedly mounted on the connecting pin 3, which is conically shaped on its underside 15 facing the inner elastomer layer 9.
  • the inner elastomer layer 9 has a significantly greater radial thickness than the other elastomer layers 10 to 12. The increased thickness leads to a relation to the other elastomer layers 10 - 12 enlarged form factor F. Thus, the inner E- lastomerlage 9 compared to the other elastomer layers 10 - 12 significantly softer.

Abstract

L'invention concerne un ressort multicouche, notamment pour véhicules ferroviaires, comprenant une partie de raccordement intérieure et une partie de raccordement extérieure et au moins deux couches de ressort situées entre, à base d'une couche d'élastomère et d'une couche de tôle, disposées de manière alternée. Les couches d'élastomère sont assemblées par vulcanisation, dans chaque cas avec les parties de raccordement et les couches de tôle et les couches d'élastomère des couches du ressort présentent différentes épaisseurs les unes par rapport aux autres. Le ressort multicouche présente un plateau d'appui à contour sensiblement conique, qui est disposé dans le sens de sollicitation, au-dessus de la couche de ressort la plus épaisse. Lorsque le ressort est sollicité, c'est d'abord la partie intérieure de la couche la plus souple qui vient s'appuyer sur le plateau d'appui. A mesure que la sollicitation augmente, les parties extérieures de la couche la plus souple s'appuient elles aussi de manière croissante et continue sur le plateau d'appui, puis sont suivies des autres couches du ressort. Le contour du plateau d'appui influe sur la courbe caractéristique du ressort.
