Definitions

  • the invention relates to a bellows or part of a bellows of a transition between two articulated parts of a vehicle, wherein cord threads are arranged as an insert in an elastomer layer.
  • Bellows or bellows are part of a transition between two articulated vehicles.
  • Such a transition consists in detail of a transition bridge, a joint and a bellows surrounding the bridge or the joint.
  • This bellows essentially serves to protect the passengers when changing between the individual articulated vehicles.
  • Such a bellows or corrugated bellows must have extreme deformability due to the relative movements that occur between the individual vehicles. This means that such a bellows must be able to give in to all the pitch, roll and offset movements of the two articulated vehicles relative to each other.
  • a bellows or corrugated bellows is known from DE-A 1 -3 035 159, a cord fabric being arranged as an insert in an elastomer layer, and the corrugations or corrugations being formed in one piece in their bulge, in accordance with the preamble of claim 1.
  • bellows and bellows are known. Such bellows have extreme elasticity and can also be folded up extremely, so that extreme cornering is also possible with such a bellows.
  • bellows are very complex to manufacture, as was also mentioned at the beginning. This is essentially due to the fact that each shaft or fold consists of individual strips of fabric which are sewn together to form the fold or shaft in a correspondingly shaping manner. A It would now be easier to produce such waves or folds by embedding a fabric layer between two elastomer layers and vulcanizing such a structure entirely. However, it has been found that satisfactory results cannot be achieved with a conventional fabric insert.
  • the invention is therefore based on the object to produce a material for a bellows or part of a bellows, which is able to give way to this elongation when the surrounding elastomeric jacket is elongated, but has increased stability, in particular against deflection of the bellows, as an insert two crosswise arranged cord fabrics are provided.
  • the cord fabric is vulcanized between two elastomer layers, whereby two cord fabrics arranged crosswise one above the other can be provided as an insert in order to be able to provide a relatively high rigidity against deflection of the bellows without having to give up the elasticity in the longitudinal direction of the bellows.
  • the warp or weft threads lie crosswise here. It is provided in one embodiment that the warp and weft threads of the respective fabric layer run at an angle between 45 ° and 90 °, in particular between 60 ° and 90 °.
  • warp or weft threads of one fabric layer run at an angle of 60 ° to the warp threads or weft threads of the other fabric layer, since the warps in the edge area, i.e. H. are very small in the leg area of the corner of a shaft or fold.
  • the proportion by weight of the fabric of the fabric insert to the elastomer portion is between 15% and 50%, but preferably about 40%. Such a high proportion of fabric enables the bellows to be very stable and durable.
  • the invention also relates to a method for producing a bellows or a part of a bellows for a transition between two vehicles which are connected to one another in an articulated manner, a method of this type being distinguished according to the invention in that an elastomer layer is inserted into a mold with a fold or corrugated contour, a cord fabric layer can be inserted on the elastomer layer and a further elastomer layer can be placed on this cord fabric layer, the connection of the elastomer layers to one another and to the cord fabric layer being brought about by vulcanization.
  • the vulcanization is carried out by hot vulcanization at about 170 to 210 bar, preferably at about 200 bar.
  • the graphic representation shows what is meant by "a wave of a fold, for example a corner element of a fold or wave as part of a bellows and a bellows".
  • a wave or fold of a bellows presents itself as an encircling element of a tunnel-shaped bellows, which is composed of several folds or waves arranged one behind the other.
  • a tunnel-shaped bellows shows four corners, so that each fold or corrugation has four corner elements.
  • the corner elements are thus at an angle of 90 ° to each other.
