Description
Fuelle o parte de un fuelle de una intercomunicación entre dos partes articuladas unidas entre sí de un vehículo (tejido cord).Bellows or part of a bellows of a intercommunication between two articulated parts linked together of a vehicle (cord fabric).
La presente invención se refiere a un fuelle o a una parte de un fuelle de una intercomunicación entre dos partes articuladas unidas entre sí, de un vehículo, estando dispuestas en una capa de elastómero como inserto fibras de cord. Los fuelles ondulados o plegados son parte integrante de una intercomunicación entre dos vehículos articulados unidos entre sí. Una intercomunicación de esta clase comprende, en detalle, un puente de intercomunicación, una articulación y un fuelle que rodea el puente o la articulación. Este fuelle se utiliza esencialmente para la protección de los pasajeros al pasar entre los diferentes vehículos articulados unidos entre sí. Un fuelle plegado u ondulado debe presentar, debido a los movimientos relativos que se presentan entre los diferentes vehículos, una capacidad de deformación extrema. Es decir, un fuelle de esta clase debe estar en condiciones de ceder a los movimientos de cabeceo, balanceo y desplazamiento relativos de los dos vehículos articulados y unidos entre sí.The present invention relates to a bellows or a part of a bellows of an intercom between two parties articulated together of a vehicle, being arranged in a layer of elastomer as cord fibers insert. Bellows corrugated or folded are an integral part of an intercom between two articulated vehicles linked together. A intercommunication of this class comprises, in detail, a bridge of intercom, a joint and a bellows surrounding the bridge or the joint. This bellows is used essentially for the Passenger protection when passing between different vehicles articulated together. A folded or wavy bellows should present, due to the relative movements that occur between Different vehicles, extreme deformation capacity. It is say, a bellows of this class must be able to yield to the relative pitching, balancing and displacement movements of the two vehicles articulated and linked together.
En la fabricación de las diferentes ondas de un fuelle ondulado de esta clase se procede de tal manera que éste, especialmente en las zonas de las esquinas, está constituido de tiras que discurren en una dirección periférica del fuelle, que están pegadas o cosidas entre sí para la formación de un ondulado en forma de U de la onda. Para la fabricación de un fuelle completo se cosen entre sí las diferentes ondas.In the manufacture of the different waves of a Wavy bellows of this class proceeds in such a way that it, especially in the corner areas, it is constituted of strips that run in a peripheral direction of the bellows, which they are glued or sewn together to form a wavy U-shaped wave. For the manufacture of a complete bellows the different waves are sewn together.
De ello resulta claramente que la fabricación de un fuelle de esta clase requiere un gran dispendio y con ello es caro. A ello hay que añadir que las costuras forman deformaciones, que rozan en las ondas contiguas y llevan necesariamente al desgaste de estas ondas, que en este caso reduce el espesor del material.It follows clearly that the manufacture of a bellows of this class requires a large expense and with it is expensive. To this we must add that the seams form deformations, that rub in the adjacent waves and necessarily lead to wear of these waves, which in this case reduces the thickness of the material.
En la fabricación de los diversos pliegues de un fuelle plegado se cosen las diferentes tiras de material en forma de acordeón en sus bordes longitudinales entre sí, con lo cual los bordes originados con ello se engarzan con carriles en forma de U. También en este caso es muy elevado el gasto para la fabricación.In the manufacture of the various folds of a folded bellows sew the different strips of material in shape accordion at their longitudinal edges with each other, thereby edges originated from it are linked with U-shaped rails. Also in this case the expense for the manufacturing.
Por el documento US-PS 21 26 837 se conoce la fabricación de un fuelle que presenta un inserto textil con fibras cord. Sin embargo, en este fuelle, no se ha formado el fuelle plegado u ondulado, sino como fuelle de paredes lisas. Es decir, si durante la marcha por una curva, el fuelle se extiende en un lado como una cinta de goma, mientras que en el lado opuesto se contrae, y con ello también se abomba o adelgaza. Con ello existe el peligro de que debido a la reducción de la sección transversal de la transición, el recinto de paso se reduce. Además, existe el peligro de que en el caso de la marcha en curvas extremas se rompa simplemente el fuelle. Por el documento DE-A1-3035159 se conoce un fuelle plegado u ondulado en el que se ha dispuesto una capa de elastómero como inserto en el tejido de cord, y con ello las ondas o los pliegues están formados en su bombeado de una sola pieza, de acuerdo con el preámbulo de la reivindicación 1. Como ya se ha indicado al principio, se conocen fuelles plegados y ondulados. Tales fuelles tienen una capacidad de dilatación extrema y pueden también, de manera extrema, plegarse, de tal manera que con un fuelle de esta clase son posibles también marchas en curvas extremas. Sin embargo, tales fuelles son muy costosos en la fabricación, como asimismo ya se ha indicado al principio. Esto radica esencialmente en que cada onda o pliegue está formado de tiras de tejido individuales, que para la formación del pliegue o de la onda están cosidas entre sí de una forma correspondiente. Una facilitación de la producción de tales ondas o pliegues se daría, sí la capa de tejido se incluyera entre dos capas de elastómero, y se vulcanizará en una formación de esta clase en su conjunto. Ha resultado, sin embargo, que con el inserto de tejido usual no se consiguen ningún resultado satisfactorio. Esto es debido a que, como se ha demostrado, en la capa de tejido durante la vulcanización, debido a la formación en el molde, no permanece exactamente entre las dos capas de elastómero, sino que más bien, debido al denominado comportamiento de contracción en caliente del tejido, se traslada hacia el interior entre las dos capas. Es decir, que la capa de elastómero en un lado es relativamente gruesa, mientras que en la capa opuesta, la capa de tejido aflora. La consecuencia de ello es que un fuelle construido de esta forma presenta sólo una duración reducida. El motivo de ello hay que buscarlo en que en la vulcanización tiene lugar una deformación, que el inserto textil no está en condiciones de absorber.For US-PS 21 26 837 it is known to manufacture a bellows that has an insert textile with cord fibers. However, in this bellows, it has not formed the bellows folded or wavy, but as bellows walls smooth. That is, if during the march by a curve, the bellows is extends on one side like a rubber tape, while on the side opposite it contracts, and with it it also bulges or thins. With this exists the danger that due to the reduction of the section transverse of the transition, the passage enclosure is reduced. Further, there is a danger that in the case of extreme cornering just break the bellows. For the document DE-A1-3035159 a bellows is known folded or corrugated in which an elastomer layer is disposed as an insert in the cord fabric, and with it the waves or folds are formed in their one-piece pumped, according with the preamble of claim 1. As already indicated to In principle, folded and corrugated bellows are known. Such bellows they have an extreme expansion capacity and can also extreme way, fold, so that with a bellows of this class are also possible marches in extreme curves. Nevertheless, such bellows are very expensive in manufacturing, as well as It was indicated at the beginning. This is essentially that each wave or fold is formed of individual tissue strips, which for the formation of the fold or wave they are sewn together in a corresponding way. A facilitation of the production of such waves or folds would occur, if the tissue layer were included between two layers of elastomer, and will be vulcanized in a formation of This class as a whole. It has turned out, however, that with the usual tissue insert no results are achieved satisfactory. This is because, as demonstrated, in the tissue layer during vulcanization, due to the formation in the mold does not remain exactly between the two layers of elastomer, but rather, due to the so-called behavior hot shrinkage of the tissue, moves to the inside between the two layers. That is, that the elastomer layer in one side is relatively thick, while on the opposite layer, the layer of tissue emerges. The consequence of this is that a bellows Built in this way it has only a reduced duration. The reason for this we must look for it in that in vulcanization it has place a deformation, that the textile insert is not in condition of absorbing
La presente invención tiene por ello como objeto fabricar un material para un fuelle, que esté en condiciones de con el alargamiento del elastómero que lo rodea cede a este alargamiento, pero que presenta una estabilidad elevada, especialmente contra la flexión del muelle como inserto se ha previsto tejidos cord dispuestos cruzados uno encima de otros.The present invention therefore has as its object manufacture a material for a bellows, which is in condition to elongation of the elastomer surrounding it yields to this elongation, but presenting high stability, especially against spring flexion as an insert it has provided cord fabrics arranged crossed one on top of the other.
En este punto se ha de indicar que con la correspondiente forma se produce un fuelle de ésta clase en piezas, es decir, como pliegues u ondas individuales, si a continuación se unen entre sí para la formación del pliegue o se pueden producir paredes laterales, segmentos del fondo o de la cubierta con varios pliegues dispuestos uno tras otro, o segmentos de paredes laterales u ondas, o con la forma correspondiente grande existe la posibilidad de producir fuelles completos o mitades de fuelles. Es ventajoso con un fuelle o elemento de fuelle producido de una sola pieza según un principio de esta clase, que también presentan estos una elevada duración, lo que resulta porque la superficie del componente se puede mantener absolutamente plana. Es decir, no existe, al contrario de con el estado actual de la técnica, ninguna deformación, solapes o deformaciones en la superficie, que pueden producir un rozamiento entre las ondas o pliegues contiguos y provocar un desgaste prematuro del fuelle en su conjunto. Además, ha resultado que en relación a la amortiguación de sonido y calor, por lo menos se pueden conseguir los mismos valores como con un fuelle según el estado de la técnica conocida.At this point it should be noted that with the correspondingly a bellows of this class is produced in pieces, that is, as individual folds or waves, if then join together for crease formation or can occur side walls, bottom or roof segments with several folds arranged one after the other, or segments of side walls or waves, or with the corresponding large form there is the possibility of producing full bellows or bellows halves. It is advantageous with a bellows or bellows element produced from a single piece according to a principle of this class, which also present these a high duration, which results because the surface of the component can be kept absolutely flat. That is, no there is, contrary to the current state of the art, none deformation, overlaps or deformations on the surface, which may produce friction between adjacent waves or folds and cause premature wear of the bellows as a whole. Further, It has turned out that in relation to sound and heat damping, at least you can get the same values as with a bellows according to the known state of the art.
En detalle se ha previsto que el tejido cord se vulcanice entre dos capas de elastómero, pudiéndose prever como inserto dos tejidos de cord dispuestos uno encima del otro, para conseguir una rigidez relativamente alta contra la flexión del fuelle, sin que tenga que ceder la elasticidad en la dirección longitudinal del fuelle. Es decir, que las fibras de urdido o de la trama se encuentran en cruz. Para ello se ha previsto en una forma de realización, que los hilos de urdido o de la trama discurran en la capa de tejido correspondiente, formando ángulos comprendidos entre 45º y 90º, especialmente entre 60º y 90º. Para ello ha resultado especialmente ventajoso sí los hilos de urdido o de trama discurren en la capa de tejido en ángulos de 60º con relación a los hilos de urdido o de trama de la otra capa de tejido, ya que entonces las deformaciones en la zona del borde, es decir, en la zona de los lados del ángulo de una onda o de un repliegue son muy reducidos.In detail it is envisioned that the cord fabric is vulcanize between two layers of elastomer, being able to provide as I insert two cord fabrics arranged on top of each other, to achieve relatively high stiffness against flexion bellows, without having to yield the elasticity in the direction Longitudinal bellows. That is, the fibers of the warp or the plot are found in cross. This is planned in a way of embodiment, that the warp or weft threads run in the corresponding tissue layer, forming angles comprised between 45º and 90º, especially between 60º and 90º. For this he has especially advantageous result if warp or weft threads they run in the fabric layer at angles of 60º in relation to the warp or weft threads of the other fabric layer, since then the deformations in the edge zone, that is, in the zone of the sides of the angle of a wave or a fold are very reduced
Según una característica especial de la invención, se ha previsto que la parte de peso del tejido del inserto de tejido en relación a la parte de elastómero este comprendida entre 15% y 50%, preferentemente, sin embargo, aproximadamente 40%. Mediante una parte de tejido tan elevada se permite una elevada estabilidad y duración del fuelle.According to a special feature of the invention, it is provided that the tissue weight part of the tissue insert in relation to the elastomer part this between 15% and 50%, preferably, however, approximately 40% Through such a high part of the fabric, It allows high stability and durability of the bellows.
El objeto de la invención es asimismo un procedimiento para la fabricación de un fuelle o una parte de un fuelle de una transición entre dos vehículos unidos, articulados entre sí, distinguiéndose un procedimiento de esta clase según la invención gracias a que se ha colocado en un molde con un contorno plegado u ondulado de una capa de elastómero sobre el que la capa de elastómero se puede colocar una capa de tejido cord y sobre esta capa de tejido cord, otra capa de elastómero, originándose su unión de las capas de elastómero entre sí y con la capa de tejido, mediante el método de vulcanización. La vulcanización tiene lugar mediante la vulcanización en caliente a aproximadamente 170 a 210 bar, preferentemente a unos 200 bar. Se ha demostrado que especialmente en el empleo de inserto de tejido, de un tejido cord, se evitan las deformaciones en la zona del borde de la onda o del pliegue, porque el molde durante el proceso de vulcanización se purga. Para ello se da al material de elastómero la posibilidad de relajarse, lo que finalmente también deshace las deformaciones en la zona del borde de la onda, ya que mediante este proceso de relajamiento puede salir el material de elastómero sobrante del molde.The object of the invention is also a procedure for manufacturing a bellows or a part of a bellows of a transition between two united, articulated vehicles each other, distinguishing a procedure of this kind according to the invention because it has been placed in a mold with an outline folding or corrugated an elastomer layer on which the layer of elastomer can be placed a layer of cord fabric and on this cord fabric layer, another elastomer layer, originating its union of the elastomer layers with each other and with the fabric layer, by the method of vulcanization. Vulcanization takes place by hot vulcanization at approximately 170 to 210 bar, preferably about 200 bar. It has been shown that especially in the use of tissue insert, of a cord fabric, deformations in the area of the edge of the wave or of the fold, because the mold during the vulcanization process is purge. For this, the elastomer material is given the possibility of relax, which eventually also undo the deformations in the area of the edge of the wave, since by this process of The excess elastomer material can escape from the relaxation mold.
La representación gráfica muestra lo que "se entiende como una onda de un pliegue, por ejemplo, de un elemento de esquina de un pliegue o de una onda como parte de un fuelle y un fuelle".The graphic representation shows what "is understood as a wave of a fold, for example, of an element corner of a crease or wave as part of a bellows and a bellows".
Una onda o pliegue de un fuelle se representa como un elemento periférico de un fuelle en forma de túnel, que está formado de varios pliegues u ondas dispuestos uno tras otro. Un fuelle en forma el túnel tal muestra cuatro esquinas, de tal manera que en conjunto, cada pliegue u onda presenta cuatro elementos en ángulo. Los elementos en ángulo forman entre sí un ángulo de 90º.A wave or fold of a bellows is represented as a peripheral element of a tunnel-shaped bellows, which is formed of several folds or waves arranged one after another. A bellows shaped tunnel shows four corners, such so that together, each fold or wave has four angled elements The angled elements form a 90º angle.
