Definitions

  • the invention relates to a bellows or bellows or part of a Transition between two articulated parts of one Vehicle, the waves or folds in one piece in their curvature are formed, with a textile insert in an elastomer layer is vulcanized.
  • Bellows or corrugated bellows are part of a transition between two articulated vehicles.
  • Such a transition consists in detail of a transition bridge, a joint and a the bellows or the bellows surrounding the joint.
  • This bellows serves in Essentially protecting passengers when changing between individual articulated vehicles.
  • Such a fold or Bellows must be due to the relative movements that occur extreme deformability between the individual vehicles exhibit. This means that such a bellows must be able to Rolling and offset movements of the two articulated with each other to give connected vehicles relative to each other.
  • the invention is therefore based on the object, a bellows or a part to produce a bellows, the manufacture being simple and cost-saving should be, and moreover the bellows should have a long service life.
  • the textile insert is designed as a knitted fabric. It has been shown that at Using a knitted fabric e.g. as a knitted fabric, the fabric layer exactly between the two layers of elastomer during vulcanization a shape that remains. Because the shape of a bellows or part of it is three-dimensional, the deformation is preferably multiaxial. This can be explained by the fact that the knitted fabric has a certain intrinsic elasticity which causes the Tissue yields plastically during vulcanization, that is is deformable. This property is further favored by the fact that after an advantageous development of the invention, the knitted fabric, so for example a knitted fabric that has elastic threads.
  • Knitwear in principle has a similar elasticity or Has deformability, as the surrounding layers from the Have elastomer material.
  • Heat shrink behavior of a conventional plastic fabric means that the fabric moves inwards through the elastomer layer, with the result that the durability of such a fabric is greatly reduced.
  • the Shrinkage process cannot be completely prevented, however, is due to the elasticity or deformability of the knitted fabric ensures that not through the inside, as in the prior art Elastomer layer migrates through, because it is able toshrinking process due to its inherent elasticity or deformation compensate.
  • the knitted fabric between two Vulcanized elastomer layers, with two offset as an insert Textile layers of knitted fabric arranged one above the other can be to a relatively high stiffness against deflection of the To be able to provide bellows without the elasticity in the longitudinal direction of the Having to give up Balges.
  • the Weight share of the textile insert to the elastomer content between 15% and 50%, but preferably about 40%.
  • the invention also relates to a method for producing a Bellows or part of a bellows of a transition between two articulated vehicles, such
  • the method according to the invention is characterized in that in a form with an elastomer layer is inserted into a fold or corrugated contour the elastomer layer is a layer of a knitted fabric and on top of it A further elastomer layer can be inserted in the knitted fabric, the Connection of the elastomer layers with each other and with the Knitwear is accomplished by vulcanization.
  • the vulcanization takes place by means of hot vulcanization at about 170 to 210 bar, preferably at about 200 bar.
  • the graphic representation shows what "under a wave a fold, for example a corner element of a fold or shaft as part a bellows and a bellows "is understood.
  • a wave or fold of a bellows is a revolving element of a tunnel-shaped bellows made up of several in a row arranged folds or waves composed.
  • a tunnel-shaped bellows shows four corners, making a total of any fold or Shaft has four corner elements.
  • the corner elements are thus in one Angle of 90 ° to each other.
