Description
Fuelle o parte de un fuelle para un paso entre dos partes unidas entre sí de manera articulada de un vehículo "tejido de punto".Bellows or part of a bellows for a passage between two parts linked together in an articulated manner of a vehicle "knitting".
El invento hace referencia a un fuelle ondulado o plegado o parte de un paso entre dos partes de un vehículo unidas entre sí de manera articulada, en que las ondulaciones o pliegues tienen su curvatura conformada de una pieza, de modo que hay una capa de elastomero vulcanizado en un componente textil.The invention refers to a wavy bellows or folding or part of a passage between two parts of a vehicle attached each other in an articulated way, in which the undulations or folds they have their curvature conformed of a piece, so that there is a vulcanized elastomer layer in a textile component.
Los fuelles de pliegues u ondulaciones son componentes de un paso entre dos vehículos unidos de modo articulado entre sí. Uno de tales pasos consiste individualmente en un puente de paso, una articulación y un fuelle que circunda respectivamente el puente y la articulación. Dicho fuelle sirve esencialmente de protección para los pasajeros cuando pasan entre los vehículos individuales unidos entre sí deforma articulada. Debido a los movimientos relativos que se producen entre los vehículos individuales, tal fuelle de pliegues u ondulaciones debe tener una extrema capacidad de deformación. Es decir, uno de tales fuelles debe estar en condiciones de ceder ante todos los movimientos de cabeceo, balanceo y desplazamiento de ambos vehículos unidos de modo articulado entre sí.The bellows of folds or undulations are one-step components between two articulated vehicles each. One such step consists individually of a bridge by the way, a joint and a bellows that surrounds respectively The bridge and the joint. Said bellows essentially serves as protection for passengers when they pass between vehicles individual joined together deformed articulated. Due to relative movements that occur between vehicles individual, such bellows folds or undulations must have a Extreme deformability. That is, one of such bellows must be able to give in to all movements of pitching, balancing and displacement of both vehicles so united articulated with each other.
Al fabricar las ondas individuales de uno de estos fuelles de ondulaciones ahora se procede de manera que las mismas estén construidas de tiras dispuestas a lo largo de la periferia del fuelle, especialmente en la zona de las esquinas que, para formar la curvatura en U de la onda, se pegan o cosen entre sí. Luego, para fabricar un fuelle completo se cosen las ondulaciones individuales unas a otras.When manufacturing the individual waves of one of these ripples bellows now proceed so that the they are constructed of strips arranged along the periphery of the bellows, especially in the corner area that, to form the U-wave curvature, they stick or sew each other. Then, to make a complete bellows, the undulations are sewn individual to each other.
De ello se desprende que la fabricación de uno de tales fuelles es muy costosa, y por tanto cara. La causa de ello es que las costuras causan deformaciones que rozan con las ondulaciones vecinas y producen irremisiblemente el desgaste de tales ondulaciones, lo que en este caso reduce la resistencia del material.It follows that the manufacture of one of Such bellows is very expensive, and therefore expensive. The cause of it is that seams cause deformations that rub against undulations neighbors and irremissibly produce the wear of such undulations, which in this case reduces the resistance of the material.
Al fabricar los pliegues individuales de un fuelle de pliegues se cosen los cantos longitudinales de las tiras individuales de material entre sí a modo acordeón, uniendo los cantos resultantes mediante perfiles en forma de U. También en este caso el coste de la fabricación es muy elevado.When manufacturing the individual folds of a Fold bellows sew the longitudinal edges of the strips individual material with each other accordion mode, joining the resulting edges through U-shaped profiles. Also in this In case the cost of manufacturing is very high.
Tal como se ha dicho al inicio, se conocen fuelles de pliegues y fuelles de ondulaciones. Dichos fuelles tienen una extrema capacidad de estiramiento y también pueden plegarse de manera extrema, de modo que con tales fuelles también resultan posibles extremados recorridos curvados. No obstante, tales fuelles tienen una fabricación muy costosa, tal como se ha indicado anteriormente. Esto se debe esencialmente al hecho de que cada ondulación o pliegue, respectivamente, está hecho de tiras individuales de tejido, que para formar el pliegue o ondulación se cosen entre sí dándoles la correspondiente forma. Se facilitaría la fabricación de tales ondulaciones o pliegues si se insertase una capa de tejido entre dos capas de elastomero y se vulcanizara tal conformación en su totalidad. En todo caso se ha puesto de manifiesto que no se consiguen resultados satisfactorios con la inserción de tejidos usuales. Esto se debe al hecho de que -tal como se ha manifestado - la capa de tejido no queda exactamente en el centro de ambas capas de elastomero durante la vulcanización, debido a la conformación adoptada para darle forma, sino que, a causa del denominado comportamiento de contracción térmica del tejido, se desplaza hacia dentro entre las capas. Es decir, la capa de elastomero es relativamente gruesa en un costado, mientras que en la capa opuesta sale el tejido. La consecuencia de ello es que el fuelle así construido presenta únicamente una reducida consistencia. El motivo de esto reside en el hecho de que al vulcanizar se produce una deformación, que la inserción textil no está en condiciones de ceder.As stated at the beginning, they are known fold bellows and undulation bellows. These bellows have extreme stretching capacity and can also be folded from extreme way, so that with such bellows they also result possible extreme curved paths. However, such bellows They have a very expensive manufacturing, as indicated previously. This is essentially due to the fact that each undulation or crease, respectively, is made of strips individual tissue, which to form the crease or ripple is they sew each other giving them the corresponding shape. It would facilitate the manufacture of such undulations or folds if a layer of fabric between two layers of elastomer and will be vulcanized such conformation in its entirety. In any case it has become manifest that satisfactory results are not achieved with the insertion of usual tissues. This is due to the fact that -like it has manifested itself - the tissue layer is not exactly in the center of both elastomer layers during vulcanization, due to to the conformation adopted to shape it, but because of the called thermal shrinkage behavior of the tissue, it Shifts in between layers. That is, the layer of The elastomer is relatively thick on one side, while on the Opposite layer leaves the tissue. The consequence of this is that the Bellows thus constructed presents only a reduced consistency. The reason for this lies in the fact that vulcanizing occurs a deformation, that the textile insert is not in a position to give.
A través de la patente DE-3.035.159 se conoce la construcción de un fuelle, en el cual hay una inserción de tejido colocada entre dos capas de elastomero. Los hilos de trama de este tejido están ligados, a modo de una unión giratoria, por medio de los hilos de urdimbre. Tal tejido cede en el sentido de los hilos de urdimbre pero no en dirección de los hilos de trama. Por consiguiente, un fuelle con tal inserción de tejido es elástico en el sentido de los hilos de trama, de manera que a largo tiempo existe el peligro de que el fuelle sufra daños puesto que la inserción se desprende de los elastomeros que lo circundan.Through the patent DE-3,035,159 the construction of a bellows is known, in which there is an insertion of tissue placed between two layers of elastomer The weft threads of this fabric are linked, by way of of a rotating union, by means of warp threads. Such fabric yields in the direction of the warp threads but not in address of the weft threads. Therefore, a bellows with such tissue insertion is elastic in the sense of weft threads, so that in a long time there is a danger that the bellows suffer damage since the insert is detached from the elastomers that surround it.
Por tanto, el invento tiene por objeto fabricar un fuelle o parte de un fuelle, de modo que dicha fabricación sea sencilla y económica, y al mismo tiempo el fuelle presente una larga duración.Therefore, the invention aims to manufacture a bellows or part of a bellows, so that said manufacturing is simple and economical, and at the same time the bellows present a long duration.
El objeto se resuelve, de acuerdo con el invento, gracias a que la inserción está conformada como malla. Se ha puesto de manifiesto que con el uso de una malla, por ejemplo como género de punto, la inserción de tejido queda exactamente entre ambas capas de elastomero, mientras se vulcaniza en un molde. Dado que la forma de un fuelle o de parte de la misma, es tridimensional, la deformación se produce preferiblemente multiaxial. Puede comprenderse que, dado que la malla presenta una cierta elasticidad propia, ocurre que durante la conformación el tejido cede plásticamente durante la vulcanización, es decir, es deformable. Esta propiedad aun se ve favorecida por el hecho de que después de un ventajoso desarrollo del invento la malla de tejido, como por ejemplo un tejido de punto, presenta hilos elásticos. Es decir, en principio la malla tiene una elasticidad o capacidad de deformación parecida a la que poseen las capas de material elastomero que las circunda. Tal como ya se ha dicho el comportamiento de contracción térmica de un tejido de plástico convencional tiene como consecuencia de que el tejido se desplaza hacia al interior a través de la capa de elastomero, con el resultado de que se reduce notablemente la consistencia de un tejido de este tipo. Gracias al empleo de una malla de tejido, el proceso de contracción no puede atajarse por completo pero, debido a la elasticidad y/o capacidad de deformación de la malla, se garantiza que la misma no se desplazará, como en el actual estado de la técnica, hacia al interior a través de la capa de elastomero, dado que está en condiciones de compensar el proceso de contracción mediante su propia elasticidad o deformación.The object is resolved, according to the invention, thanks to the insertion being shaped as a mesh. Has been put clearly that with the use of a mesh, for example as a gender knitted, the insertion of tissue is exactly between both layers of elastomer, while vulcanizing in a mold. Since the form of a bellows or part of it, it is three-dimensional, the deformation preferably occurs multiaxial. May understand that, since the mesh has a certain elasticity own, it happens that during the conformation the tissue yields plastically during vulcanization, that is, it is deformable. This property is still favored by the fact that after an advantageous development of the invention the mesh fabric, as per example a knitted fabric, has elastic threads. That is, in principle the mesh has an elasticity or deformability similar to that of the layers of elastomeric material that go around As the contraction behavior has already been said thermal of a conventional plastic fabric has as consequence of the tissue moving inwards through of the elastomer layer, with the result that it is reduced notably the consistency of such a fabric. Thanks to using a fabric mesh, the contraction process cannot be completely stopped but, due to the elasticity and / or ability to deformation of the mesh, it is guaranteed that it will not move, as in the current state of the art, inwardly through of the elastomer layer, since it is able to compensate the contraction process through its own elasticity or deformation.
En este punto hay que decir que, con un correspondiente molde, puede fabricarse un tal fuelle a piezas, es decir como pliegues u ondulaciones individuales, que luego se unen entre sí para formar el fuelle, o bien pueden formarse paredes laterales, tramos de suelo o de cubierta, con varios pliegues o tramos de pared lateral, o bien ondulaciones, dispuestos unos tras otros, o con el correspondiente molde grande existe la posibilidad de fabricar fuelles o medios fuelles completos. En el fuelle o elemento de fuelle construido individualmente con este principio, la ventaja es que también presenta una alta consistencia, lo que da como resultado que la superficie del componente puede mantenerse absolutamente plana. Es decir, al contrario del actual estado de la técnica, no existe ninguna clase de elevaciones, solapamientos o deformaciones en la superficie, que puedan rozar con las ondulaciones o pliegues contiguos, y producir un desgaste prematuro de todo el fuelle. Además, se ha puesto de manifiesto que con respecto a la amortiguación de ruido y calor alcanza por lo menos los mismos buenos resultados que se consiguen con un fuelle de acuerdo con el actual estado de la técnica.At this point it must be said that, with a corresponding mold, such a bellows can be manufactured to pieces, it is say as individual folds or undulations, which are then joined each other to form the bellows, or walls may form lateral, sections of floor or deck, with several folds or lateral wall sections, or undulations, arranged one behind others, or with the corresponding large mold there is the possibility of manufacturing bellows or half full bellows. In the bellows or Bellows element constructed individually with this principle, the advantage is that it also has a high consistency, which gives as a result that the surface of the component can be maintained absolutely flat. That is, contrary to the current state of the technique, there are no elevations, overlaps or deformations on the surface, which may rub against the undulations or adjacent folds, and produce premature wear Of all the bellows. In addition, it has been revealed that with regarding noise and heat damping it reaches at least the same good results that are achieved with a bellows of according to the current state of the art.
En particular se ha previsto que la malla de tejido se vulcanice entre dos capas de elastomero, de manera que pueden disponerse como inserción dos capas textiles de malla desplazadas una sobre otra para conseguir una rigidez relativamente elevada contra el combado del fuelle, sin tener que ceder elasticidad en sentido longitudinal del fuelle.In particular, the mesh of fabric is vulcanized between two layers of elastomer, so that two mesh textile layers can be arranged as an insert shifted one over another to achieve relatively stiffness raised against the bellows, without having to give in longitudinal elasticity of the bellows.
Según una especial característica del invento se ha previsto que el porcentaje en peso de la inserción textil con respecto al porcentaje del elastomero esté comprendido entre el 15 y el 50%, siendo no obstante preferible que sea aproximadamente del 40%. Gracias a este alto porcentaje textil se obtiene una elevada estabilidad de consistencia del fuelle.According to a special feature of the invention, has predicted that the percentage by weight of the textile insert with regarding the percentage of the elastomer is between 15 and 50%, however it is preferable that it be approximately 40% Thanks to this high textile percentage a high consistency stability of the bellows.
También es objeto del invento un procedimiento para fabricar un fuelle o parte de un fuelle para un paso entre dos vehículos unidos de modo articulado entre sí, caracterizándose tal procedimiento de acuerdo con el invento por el hecho de que se coloca en un molde con un contorno de pliegue u ondulación una capa de elastomero, sobre la capa de elastomero se aplica una capa de una malla textil y, sobre dicha malla textil se aplica otra capa de elastomero, consiguiéndose la unión de las capas de elastomero entre sí y con la malla textil con ayuda de vulcanización. La vulcanización se lleva a cabo mediante vulcanización en caliente entre 170 y 210 bar, preferiblemente a unos 200 bar. Ahora se ha puesto de manifiesto que, de modo especial al utilizar inserciones textiles de malla, pueden evitarse ampliamente deformaciones en la zona del borde de la ondulación o pliegue, ventilándose el modelo durante el proceso de vulcanización. Así se da al material elastomero la posibilidad de distenderse, lo cual elimina deformaciones en la zona del borde de la ondulación, puesto que con este proceso de distensión puede salir del molde material elastomero sobrante.A process is also object of the invention. to make a bellows or part of a bellows for a step between two vehicles linked in an articulated manner, characterizing such procedure according to the invention by the fact that place a layer in a mold with a fold or wavy contour elastomer, a layer of one is applied to the elastomer layer textile mesh and, on said textile mesh another layer of elastomer, achieving the union of elastomer layers between Yes and with the textile mesh with the help of vulcanization. The vulcanization is carried out by hot vulcanization between 170 and 210 bar, preferably at about 200 bar. Now it has revealed that, especially when using inserts mesh textiles, deformations in the area of the edge of the undulation or crease, venting the model during the vulcanization process. This is how the material is given elastomer the possibility of distending, which eliminates deformations in the area of the edge of the undulation, since with This stretching process can leave the mold elastomeric material surplus.
En la representación del dibujo, explicamos lo que se entiende con la frase "debajo de una ondulación o de un pliegue, por ejemplo un elemento de esquina de un pliegue u ondulación como parte de un fuelle o un fuelle".In the representation of the drawing, we explain what which is understood by the phrase "under a ripple or a fold, for example a corner element of a fold or undulation as part of a bellows or a bellows. "
Una ondulación o pliegue de un fuelle se representa como un elemento circundante de un fuelle en forma de túnel, compuesto por varios pliegues u ondulaciones dispuestas unas tras otras. Un fuelle en forma de túnel como este presenta cuatro esquinas, de modo que cada pliegue u ondulación presenta en conjunto cuatro elementos de esquina. Por tanto, los elementos de equina forman entre sí un ángulo de 90º.A ripple or fold of a bellows is represents as a surrounding element of a bellows in the form of tunnel, composed of several folds or undulations arranged after others. A tunnel-shaped bellows like this presents four corners, so that each fold or undulation presents together Four corner elements. Therefore, the equine elements they form an angle of 90º to each other.
