Definitions

  • the invention relates to an elastic bearing for rails of rail vehicles of the type mentioned in the preamble of claim 1.
  • Elastic bearings for rails of rail vehicles are known in different designs. They serve to reduce the noise emitted by rail vehicles and transmitted to the ground. Furthermore, the underground and the wheel sets of the rail vehicles are protected by such elastic bearings. This is particularly important for bridges, tunnels and other artificial rail underlays. Such an elastic bearing can also be used successfully for noise reduction in residential areas.
  • a particularly advantageous embodiment is described in DE-A 3 341 681. Due to its variable preload, such a bearing is able to be adjusted to different resonance vibrations. This enables noise and structure-borne noise to be reduced in the particularly disruptive frequency ranges. However, such a bearing is essentially restricted to certain wheelset loads and certain speed ranges. As a result, different storage designs are required for different rail vehicles, such as trams and federal rail vehicles. Such bearings can also take up a relatively large amount of space and have an overall height which is difficult in special cases.
  • the object of the invention is to provide an elastic bearing of the design described at the outset, which enables a compact structure, can be adjusted very well to different requirements and which, moreover, can be produced using little material.
  • the side rubber layer even alone, should be easily replaceable, e.g. even if the rail is already clamped in the warehouse.
  • the rubber plate has depressions or elevations on one or both surfaces which are embedded in corresponding surface designs of the top and / or bottom plate, and in that the edges of the top and bottom plates, with the arrangement of a flange-like, widening, have surfaces running perpendicularly and parallel to one another, between which there is a connecting rubber layer which has vulcanized-on metal support strips and which is not formed in one piece with the rubber plate.
  • the rubber plate has any flexibility with regard to its wall thickness. This enables loads to be taken up as required.
  • this arrangement means that lateral forces can also be effectively absorbed in this area. Such transverse forces are also absorbed by the rubber layer, which lie between the flange-like widenings of the edges.
  • the lateral force can be absorbed more in the rubber layer connecting the edges.
  • This different variation option can be used particularly when a certain height is important and possibly tilting movements are to be kept within very narrow limits.
  • the quality of the rubber layer between the top and bottom plate can be matched to the rubber layer that connects the edges of the top and bottom plate. As a rule, the same Shore hardness is provided. It should also be taken into account here that the pretension generated by the screw bolts leads, if possible, to the same amount of deformation in the two rubber bodies that compete with one another.
  • the rubber plate which is arranged between the top and bottom plate
  • various types of holes can be provided in order to produce a corresponding deformability and spring property.
  • these holes consist of vertical channels that can be more or less close to each other. It is important that the designs of the bores and their arrangement can be in relation to one another. It is important that the designs of the bores and their arrangement with one another lead to the lowest possible different stress states during the deformation of the rubber body.
  • the rubber plate between the top and bottom plate should have a Shore hardness A of about 50 to 65 °.
  • the hardness depends on the expected loads and what other requirements are placed on the bearing. Since these rubber plates are easily interchangeable, an elegant adaptation can also be achieved in this way.
  • the rubber plate between the top and bottom plate takes up the entire plate surface and has holes only in the zones of the bolts and base attachment. This enables the top and bottom plates to be largely relieved of bending loads. This also has the consequence that these metal plates can consist of deep-drawn sheet steel parts, which are generally less expensive than molded metal plates. Because of the ge mutual interchangeability of the plates can also result in a good adaptation to the respective need.
  • the rubber layer lying between the edges of the top and bottom plates in connection with the flange-like widening has vulcanized support strips in order to absorb transverse forces. These can create a firm connection between the top and bottom plate and still enable easy interchangeability. Thanks to the L-shaped design of the metal support strips, it can be easily and safely inserted into the space provided. Since the rubber layer between the metal strips preferably has a parallelogram-shaped cross section, a special progressive spring characteristic is also brought into this rubber body in this way.
  • the parallelogram-shaped design also allows a relatively large travel without causing damage when this travel is exhausted.
  • This rubber layer also has the advantage that it protects the interior of the bearing from dirt. If these rubber strips create a closed cavity between the top and bottom plate, an additional opening is expedient. This can preferably be arranged in the lower plate. Such an opening prevents a possible compression of air and the heat generated thereby within the bearing. Moisture inside the bearing can also be avoided.
  • the bearing consists of an upper plate (1) and a lower plate (2), between which there is a rubber plate (3).
  • Upper plate (1) and lower plate (2) are connected to each other by a bolt (4).
  • the bolt has the nut (5).
  • the bolt (4) is surrounded in a ring by a rubber body (6) which has ring supports (7) and (8) on the top and bottom. If the screw bolt (4) is tightened by adjusting the nut (5), this leads to a compression of the rubber plate (3). In connection with the rubber ring (6) this leads to a floating state of the upper plate (1) compared to the lower plate (2).
  • This preload causes a state in the bearing for a specific natural frequency which is set to the use of the respective application.
  • the upper plate (1) and the lower plate (2) have parallel surfaces (10) and (11) at the edges in connection with a flange (9). These surfaces are arranged vertically and thus run parallel to the deflection process. Between the two surfaces (10) and (11) is the rubber layer (12), which contains metal strips (13) and (14) vulcanized on both sides. This layer (12) can be easily inserted into the space provided and is used to absorb lateral forces in the bearing, such as those that can occur, for example, in curve areas and on switches.
  • the lower plate (2) has an opening (15) for ventilation.
  • Figure (2) also shows that the rubber body (3) has elevations (16) and (17) which engage in corresponding recesses in the top plate (1) and the bottom plate (2).
  • this rubber plate (3) is also suitable for absorbing transverse forces.
