Definitions

  • the invention relates to an elastomer spring, in particular for rail vehicles, comprising at least:
  • a core made of metal or plastic e.g. based on polyphenylene ether
  • An outer sleeve which is also made of metal or plastic;
  • a bottom chamber which is formed under a core offset.
  • An elastomer spring of the generic type which is described, for example, in the document DE 295 20 881 U1, is preferably used in rail vehicle technology, which will now be described in more detail below.
  • An essential aspect is the guidance of the wheel set of a rail vehicle by means of an elastic, play-free elastomer spring linear in the three spatial directions, the elastomer spring being fastened between the frame of the rail vehicle and the axle bearing.
  • the longitudinal and transverse axes of the vehicle lie in the radial direction of the guide element, and the vertical axis of the vehicle in its axial direction.
  • the main requirement is to optimize the spring characteristic in the vertical direction in order to guarantee derailment safety when the rail vehicle is unloaded and still meet the suspension requirements when it is loaded.
  • the desired ratio of the vertical stiffness in the unloaded state to that in the loaded state is usually around 0.2: 1 to 0.8: 1.
  • the vertical spring characteristic curve is linear between the unloaded and the loaded state, so the stiffness ratio is 1: 1, which in the unloaded state can mean that safety against derailment is not guaranteed.
  • a compromise must therefore be made between the vertical stiffnesses of both loading conditions.
  • the object of the invention is to provide an elastomer spring that fulfills the entire complex of requirements mentioned above.
  • the elastomer spring is constructed in several stages in the vertical direction, namely consisting of at least a first spring and a second spring, a chamber being present between two springs.
  • Fig. 1 shows a two-stage elastomer spring with an elastomer cushion
  • Fig. 2 shows a two-stage elastomer spring with a cushion in the form of a Layer spring and a system of compensating holes.
  • first spring I and second spring II each comprising a core 2, an outer sleeve 3 and a cushion 3 made of elastomeric material.
  • the cushion usually has a sloping shoulder construction.
  • the core and the outer sleeve have conical surfaces 5 and 6, respectively, which correspond with the poster.
  • Each spring is assembled as an individual component, specifically by means of a plug-groove system 8 or 9 of the core and outer sleeve components. When the core components are joined together, a compensating hole A ensures ventilation.
  • the elastomer spring is provided with a bottom chamber 11, which is formed with a core offset H in relation to the outer sleeve bottom and has a sealing plate 10 on the bottom.
  • the chamber 7 and bottom chamber 11 are designed as an air chamber, the two compensating bores B and C ensuring that the individual air volumes can compensate. If necessary, the compensating bore B can be combined with a control or regulable throttle.
  • the chamber 7 and bottom chamber 11 are filled with a damping liquid, which is especially glycol.
  • the compensating bore B is combined here with a control or regulable throttle, while the compensating bore C within the core 2 of the spring I has the function of an overflow channel between the chamber 7 and the bottom chamber 11.
  • Fig. 2 shows an elastomer spring 12, the cushion 13 is a layer spring in the form of a metal-elastomer composite.
  • the metal parts can also be replaced by an appropriate plastic, for example based on polyphenylene ether.
  • the plug-groove system 14 of the core components is here provided with a sliding system 15, for example in the form of sliding bushes.
  • the core 2 of the spring I has two compensating holes D and F. In the case of a chamber 7 and bottom chamber 11 filled with air, the compensating bore D takes over the venting of the groove of the plug-and-groove system when the springs I and II are joined together. Both the chambers 7 and 11 and the groove of the plug-and-groove system are included filled with a damping fluid, the compensating bore D has the function of an overflow channel.
  • the core and sleeve components as well as the layer components of the cushion 13 have concave or convex surfaces.
  • the core component of the spring II is also usually provided with a fastening system 16.
  • the principle of the two-stage speed shown in FIGS. 1 and 2 is also applicable to a three or multi-stage system with the formation of corresponding additional chambers, the measures of claims 2 to 13 being applicable. Usually, however, the two-stage speed of the elastomer spring is sufficient with regard to the task.
  • the sealing plate 10 can be omitted, to form a floor chamber 11 which is then open at the bottom and does not communicate with the chamber 7.
