Definitions
- the invention relates to a bellows or part of a bellows Transition between two articulated parts of one Vehicle, with a textile insert in an elastomer layer is vulcanized.
- Wrinkles 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 the bridge or the joint surrounding the bellows.
- This bellows serves in the Essentially protecting passengers when changing between individual articulated vehicles.
- Such a wrinkle or bellows must be due to the relative movements occurring 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 give connected vehicles relative to each other.
- bellows and bellows are known. Such bellows have an extreme elasticity and can also in extremely folded so that with such a bellows extreme cornering is also possible.
- bellows are very complex to manufacture, as also mentioned above has been. This is essentially due to the fact that every wave or fold is out individual strips of fabric exist, which form the fold or wave are sewn together to give a corresponding shape. A relief the production of such waves or folds would now become a problem offer that one layer of fabric between two layers of elastomer embedded and vulcanized such a structure in its entirety. It has however, it turned out that with a conventional fabric insert, none satisfactory results can be achieved.
- the invention is therefore based on the object, a bellows or a part to produce a bellows, making it simple and cost-effective should be, and moreover the bellows should have a long service life.
- the wave or Bellows integrally formed waves or folds or parts thereof has, wherein the textile insert is designed as knitted fabric. It has it has been shown that when using a knitted fabric e.g. as Knitted fabric layer exactly between the two elastomer layers, remains in a mold during vulcanization. Because the shape of a Bellows or a part of it is three-dimensional, the deformation takes place preferably multiaxial. This can be explained by the fact that the knitted fabric has a certain intrinsic elasticity, which causes that during the Shaping the fabric plastically compliant during vulcanization, that is deformable. This property is further favored by that according to an advantageous development of the invention Knitwear, for example a knitted fabric, has elastic threads.
- the knitted fabric is roughly similar in principle Has elasticity or deformability, as the surrounding Have layers of the elastomer material.
- the heat shrink behavior of a conventional plastic fabric that the fabric travels inwards through the elastomer layer with which As a result, the durability of such a fabric is strong is reduced.
- the Shrinkage process cannot be completely prevented, however, is due to the elasticity or deformability of the knitted fabric ensures that as in the prior art, they do not pass through the inside 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 rigidity 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 Another elastomer layer can be inserted, 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.
- 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 Angles of 90 ° to each other.
