DESCRIPCIONDESCRIPTION

Dispositivo para el apoyo vertical de una barra de acoplamientoDevice for vertical support of a tie rod

La presente invencion se refiere a un dispositivo para el apoyo vertical de una barra de acoplamiento segun el preambulo de la reivindicacion independiente 1 de la patente.The present invention relates to a device for vertical support of a coupling bar according to the preamble of the independent claim 1 of the patent.

De acuerdo con ello, la invencion se refiere especialmente a un dispositivo para el apoyo vertical de una barra de acoplamiento articulada en una vagon de un vehnculo especialmente ferroviario a traves de una articulacion, en el que el dispositivo presenta una instalacion de resorte de apoyo que se puede poner en contacto con la barra de acoplamiento y un soporte de fijacion, a traves del cual se puede conectar la instalacion de resorte de apoyo con la articulacion.Accordingly, the invention relates especially to a device for vertical support of an articulated coupling rod in a carriage of a specially railway vehicle through an articulation, in which the device has a support spring installation that it can be put in contact with the coupling bar and a fixing bracket, through which the support spring installation can be connected to the joint.

Tal dispositivo de apoyo se conoce, en principio, ya a partir del estado de la tecnica, y en particular a partir de la tecnica ferroviaria. Tales dispositivos sirven para el apoyo vertical de una barra de acoplamiento articulada a traves de una articulacion en un vagon o bien bastidor inferior del vagon en direccion vertical. Un apoyo en direccion vertical es especialmente necesario para posibilitar un acoplamiento perfecto de dos vagones vecinos. A tal fin, hay que procurar que la barra de acoplamiento se encuentre durante el proceso de acoplamiento siempre en el plano medio longitudinal horizontal.Such a support device is known, in principle, already from the state of the art, and in particular from the railway technique. Such devices serve for the vertical support of an articulated coupling bar through an articulation in a carriage or lower frame of the carriage in the vertical direction. A support in the vertical direction is especially necessary to enable a perfect coupling of two neighboring wagons. To this end, it must be ensured that the coupling rod is always in the horizontal longitudinal midplane during the coupling process.

La publicacion EP 1 719 684 A1 se refiere a una articulacion de resorte de elastomero con un dispositivo de apoyo vertical, en el que un soporte transversal inferior sirve para conectar un muelle de apoyo con una barra de acoplamiento de apoyo. En el dispositivo de apoyo conocido a partir de este estado de la tecnica, se pueden emplear, ademas, dos soportes longitudinales laterales que se extienden verticales, que estan conectados a traves de su zona extrema inferior con el soporte transversal, de manera que la conexion de los soportes longitudinales laterales con el soporte transversal se realiza por medio de tornillos.EP 1 719 684 A1 refers to an elastomer spring joint with a vertical support device, in which a lower cross support serves to connect a support spring with a support coupling bar. In the support device known from this state of the art, two vertical longitudinal lateral supports, which are connected through its lower end zone with the transverse support, can be used, so that the connection of the lateral longitudinal supports with the transverse support is made by means of screws.

La publicacion EP 1 955 918 A1 se refiere a un acoplamiento amortiguador medio automatico con una cabeza de acoplamiento, una barra de acoplamiento y un seguro de choque, que presenta un miembro de absorcion de energfa configurado destructivo en forma de un tubo deformable. Con el objetivo de preparar la funcionalidad adicional de la extraccion y la insercion de la barra de acoplamiento, se propone en este estado de la tecnica equipar el acoplamiento amortiguador medio con un accionamiento lineal activables para el desplazamiento axial de la barra de acoplamiento con relacion a una placa de fijacion.EP 1 955 918 A1 refers to an automatic mid-shock absorber coupling with a coupling head, a coupling bar and a crash lock, which has a destructive shaped energy absorbing member in the form of a deformable tube. With the aim of preparing the additional functionality of the extraction and insertion of the coupling bar, it is proposed in this state of the art to equip the middle shock absorber coupling with a linear drive that can be activated for axial displacement of the coupling rod in relation to a fixing plate.

La publicacion CH 356 792 A se refiere a un dispositivo para la suspension de un acoplamiento amortiguador medio en vehnculos ferroviarios, en el que a tal fin se emplea una horquilla dispuesta sobre el eje de acoplamiento, cuyos extremos estan acodados hacia abajo y estan conectados con un rodillo configurado como traviesa. La horquilla es pivotable lateralmente alrededor del eje medio vertical de una articulacion de conexion, estando previstos, ademas, medios para su recuperacion y centrado elasticos.Publication CH 356 792 A refers to a device for the suspension of an average shock absorber coupling in railway vehicles, in which a fork arranged on the coupling shaft is used for this purpose, the ends of which are angled down and connected with a roller configured as a sleeper. The fork is pivotable laterally around the middle vertical axis of a connection joint, being provided, in addition, elastic recovery and centering means.

Los dispositivos de apoyo conocidos a partir del estado de la tecnica estan realizados, en general, como apoyos configurados elasticos, en los que la estampa de apoyo esta conectada a traves de al menos un elemento de resorte con un soporte de fijacion inferior del dispositivo de apoyo. A traves del al menos un elemento de resorte se presiona la estampa de apoyo con una tension previa desde abajo en direccion vertical contra la barra de acoplamiento. La tension previa, con la que la estampa de apoyo presiona contra la barra de acoplamiento, es regulable por medio de una seleccion adecuada de la distancia vertical entre el soporte de fijacion inferior y la barra de acoplamiento y debena seleccionarse para que en un estado de reposo de la barra de acoplamiento, es decir, cuando no inciden fuerzas dinamicas en direccion vertical en la barra de acoplamiento, la barra de acoplamiento este dispuesta en la posicion medio horizontal.The support devices known from the state of the art are generally made as elastic shaped supports, in which the support print is connected through at least one spring element with a lower fixing support of the device support for. Through the at least one spring element, the support print is pressed with a pre-tension from below in a vertical direction against the coupling bar. The pre-tension, with which the support print presses against the coupling bar, is adjustable by means of an adequate selection of the vertical distance between the lower fixing support and the coupling bar and must be selected so that in a state of rest of the coupling bar, that is, when dynamic forces do not impact vertically in the coupling bar, the coupling bar is arranged in the middle horizontal position.

En dispositivos de apoyo convencionales, en los que el al menos un elemento de resorte esta formado de un material elastomero, es en general indispensable que la distancia vertical entre el soporte de fijacion y la barra de acoplamiento y, por lo tanto, la tension previa, con la que la estampa de apoyo presiona contra la barra de acoplamiento, se reajuste al menos despues de usar por primera vez el acoplamiento, puesto que con el tiempo el material elastomero del al menos un elemento de resorte se asienta y, por lo demas, no se asegura que la barra de acoplamiento este en el estado de reposo en la posicion media horizontal.In conventional support devices, in which the at least one spring element is formed of an elastomeric material, it is generally essential that the vertical distance between the fixing bracket and the coupling bar and, therefore, the pre-tension , with which the bearing pattern presses against the coupling bar, is readjusted at least after using the coupling for the first time, since over time the elastomeric material of the at least one spring element settles and, at least , it is not ensured that the coupling bar is in the resting state in the horizontal middle position.

Por otra parte, en la tecnica ferroviaria, especialmente en trenes de alta velocidad, es habitual realizar el lado frontal del saliente del morro de forma aerodinamica, para evitar partes frontales aerodinamicamente desfavorables. El saliente del morro esta provisto, en general, con una trampilla de morro, que cubre en el estado cerrado la caja de acoplamiento para proteger elementos o bien componentes de la disposicion de acoplamiento, como por ejemplo tambien el dispositivo de apoyo vertical, contra influencias del medio ambiente, como contaminacion, hielo o heladas. Se conocen trampillas de morro tanto de una pieza como tambien de dos piezas, que en el caso normal estan cerradas y solamente se abren cuando debe utilizarse el acoplamiento, tal vez cuando se encadenan con trenes de coches ferroviarios en traccion doble.On the other hand, in the railway technique, especially in high-speed trains, it is usual to perform the front side of the nose of the nose aerodynamically, to avoid aerodynamically unfavorable front parts. The nose of the nose is provided, in general, with a nose hatch, which covers in the closed state the coupling box to protect elements or components of the coupling arrangement, such as for example the vertical support device, against influences of the environment, such as pollution, ice or frost. Both one-piece and two-piece nose traps are known, which in the normal case are closed and only open when the coupling must be used, perhaps when they are chained with railroad car trains in double traction.

Los vagones, cuyo lado frontal esta configurado como saliente de morro, presentan con frecuencia un espacio de construccion muy limitado para el alojamiento del acoplamiento amortiguador medio as^ como de los componentes que pertenecen al acoplamiento amortiguador medio, en particular el dispositivo de apoyo vertical. En particular, en tales vehnculos ferroviarios, la accesibilidad para el reajuste del dispositivo de apoyo es muy limitada.The wagons, whose front side is configured as a nose protrusion, often have a very limited construction space for the housing of the medium damping coupling as well as the components belonging to the medium damping coupling, in particular the vertical support device. In particular, in such rail vehicles, the accessibility for readjustment of the support device is very limited.

De acuerdo con ello, con frecuencia solo con mucho gasto se puede reajustar un dispositivo de apoyo convencional, lo que es especialmente intensivo de tiempo y, por lo tanto, de costes.Accordingly, it is often only with a lot of expense that a conventional support device can be readjusted, which is especially time and, therefore, cost intensive.

Partiendo de esta problematica, la invencion tiene el cometido de desarrollar un dispositivo de apoyo vertical del tipo mencionado al principio, con el proposito de que se pueda ajustar o bien reajustar, de una manera facil de realizar, pero a pesar de todo efectiva, la tension previa vertical, con la que el dispositivo de poyo presiona contra la barra de acoplamiento, para que con poco gasto de tiempo y de trabajo se asegure que en su estado de reposo, la barra de acoplamiento esta siempre en la posicion media horizontal.Starting from this problem, the invention has the task of developing a vertical support device of the type mentioned at the beginning, with the purpose that it can be adjusted or readjusted, in an easy way to carry out, but in spite of everything effective, the vertical pre-tension, with which the support device presses against the coupling bar, so that with little time and labor expense it is ensured that in its resting state, the coupling bar is always in the horizontal middle position.

Este problema se soluciona por medio del objeto de la reivindicacion independiente 1 de la patente, de manera que se indican desarrollos ventajosos de la misma en las reivindicaciones dependientes 2 a 9 de la patente. Las reivindicaciones 10 a 12 se refieren, respectivamente, a un acoplamiento amortiguador medio con el dispositivo de apoyo segun la invencion.This problem is solved by means of the object of the independent claim 1 of the patent, so that advantageous developments thereof are indicated in the dependent claims 2 to 9 of the patent. Claims 10 to 12 refer, respectively, to a medium damping coupling with the support device according to the invention.

De acuerdo con ello, se propone un dispositivo de apoyo, que presenta una instalacion de resorte de apoyo que se puede poner en contacto con la barra de acoplamiento de un vehuculo ferroviario asf como un soporte de fijacion, a traves del cual la instalacion de resorte de apoyo se puede conectar con la articulacion y, ademas, con el vagon. Segun la invencion, el soporte de fijacion presenta un soporte transversal inferior para el apoyo de la instalacion de resorte de apoyo asf como dos soportes longitudinales laterales que se extienden verticalmente, a traves de los cuales se puede conectar el soporte transversal inferior con la articulacion fijada en el vagon. Para poder ajustar la tension previa vertical de la instalacion de resorte de apoyo tambien con accesibilidad muy limitada con gasto reducido de tiempo y de trabajo, esta previsto segun la invencion que la zona extrema inferior de los dos soportes longitudinales laterales este conectada, respectivamente, a traves de al menos un elemento de tension previa con el soporte transversal de tal manera que se puede regular una distancia vertical entre el soporte transversal y la barra de acoplamiento y, por lo tanto, la tension previa vertical de la instalacion de resorte de apoyo.Accordingly, a support device is proposed, which has a support spring installation that can be brought into contact with the coupling bar of a railway vehicle as well as a fixing support, through which the spring installation Support can be connected to the joint and also to the car. According to the invention, the fixing support has a lower transverse support for the support of the support spring installation as well as two lateral longitudinal supports that extend vertically, through which the lower transverse support can be connected with the fixed joint in the car. In order to be able to adjust the vertical pre-tension of the support spring installation also with very limited accessibility with reduced time and work expense, it is provided according to the invention that the lower end zone of the two lateral longitudinal supports is connected, respectively, to through at least one pre-tension element with the transverse support in such a way that a vertical distance between the transverse support and the coupling bar and, therefore, the vertical pre-tension of the support spring installation can be regulated.

A traves de la prevision de al menos un elemento de tension previa, que sirve para la conexion del soporte transversal inferior del soporte de fijacion con la zona extrema inferior de uno de los dos soportes longitudinales laterales, se puede ajustar de una manera facil de realizar tambien posteriormente, es decir, despues de que el dispositivo de apoyo y los restantes componentes han sido colocados en el saliente del morro en el vagon o bien en el bastidor inferior del vagon, la distancia vertical entre el soporte transversal y la barra de acoplamiento y, por lo tanto, la tension previa vertical de la instalacion de resorte de apoyo. En este caso, todas las etapas de trabajo para el ajuste y reajuste del dispositivo de apoyo vertical se pueden realizar a traves de una trampilla de mantenimiento o bien abertura en el saliente del morro del vetnculo. El ajuste hacia arriba y hacia debajo de la barra de acoplamiento se realiza a traves de los elementos de tension previa asociados a los dos soportes longitudinales laterales. De esta manera se puede reajustar o bien ajustar por primera vez el dispositivo de apoyo vertical con gasto de tiempo y trabajo reducido, incluso en vehnculos que solamente acondicionan un espacio de construccion muy limitado para el acoplamiento.Through the provision of at least one pre-tension element, which is used to connect the lower transverse support of the fixing support with the lower end area of one of the two lateral longitudinal supports, it can be adjusted in an easy way to perform also subsequently, that is, after the support device and the remaining components have been placed in the nose of the nose in the carriage or in the lower frame of the carriage, the vertical distance between the transverse support and the coupling bar and , therefore, the vertical pre-tension of the support spring installation. In this case, all the work steps for the adjustment and readjustment of the vertical support device can be carried out through a maintenance hatch or opening in the projection of the nose of the vehicle. The up and down adjustment of the coupling bar is carried out through the pre-tension elements associated with the two lateral longitudinal supports. In this way, the vertical support device can be readjusted or adjusted for the first time with reduced time and labor expense, even in vehicles that only condition a very limited construction space for coupling.

Segun la invencion esta previsto, por una parte, que la zona extrema inferior de los dos soportes longitudinales laterales presente, respectivamente, una rosca y, por otra parte, que los elementos de tension previa asociados a los dos soportes longitudinales presenten, respectivamente, una contra rosca correspondiente y colaboren con la rosca del soporte longitudinal correspondiente, de tal manera que cuando se aprietan los elementos de tension previa se acorta la distancia vertical entre el soporte transversal y la barra de acoplamiento y se eleva la tension previa vertical de la instalacion de resorte de apoyo.According to the invention, it is provided, on the one hand, that the lower end zone of the two lateral longitudinal supports, respectively, has a thread and, on the other hand, that the pre-tension elements associated with the two longitudinal supports present, respectively, a against the corresponding thread and collaborate with the thread of the corresponding longitudinal support, so that when the pre-tension elements are tightened the vertical distance between the transverse support and the coupling bar is shortened and the vertical pre-tension of the installation of the support spring

En este caso sena concebible que la zona extrema inferior de los dos soportes longitudinales laterales este configurada, respectivamente, en forma de casquillo y este alojada en un casquillo de grna conectado con el soporte transversal, en el que la zona extrema inferior configurada en forma de casquillo de los dos soportes longitudinales laterales esta provista, al menos por secciones, con una rosca interior. Como elemento de tension previa es adecuado en este caso un tornillo tensor (tornillo cilmdrico) con una rosca exterior configurada complementaria de la rosca interior del soporte longitudinal correspondiente. Estos elementos de tension previa realizados como tornillo tensor se extienden con preferencia, respectivamente, a traves de un agujero de paso configurado en el soporte transversal, de manera que la rosca exterior de los elementos de tension previa realizados como tornillos tensores reciben, respectivamente, la rosca interior de los soportes longitudinales correspondientes.In this case it is conceivable that the lower end zone of the two lateral longitudinal supports is configured, respectively, in the form of a bushing and is housed in a bushing connected to the transverse support, in which the lower end zone configured in the form of bushing of the two lateral longitudinal supports is provided, at least in sections, with an internal thread. As a pre-tension element, a tensioning screw (cylindrical screw) with an external thread configured complementary to the internal thread of the corresponding longitudinal support is suitable in this case. These pre-tension elements made as a tension screw preferably extend, respectively, through a through hole configured in the transverse support, so that the external thread of the pre-tension elements made as tension screws receive, respectively, the internal thread of the corresponding longitudinal supports.

De manera alternativa a ello, es concebible proveer la zona extrema inferior de los dos soportes longitudinales laterales, respectivamente, con una rosca exterior. En este caso, es ventajoso que las zonas extremas inferiores de los dos soportes longitudinales sean recibidas, respectivamente, en un agujero de paso configurado en el soporte transversal, de tal manera que la rosca exterior se extiende por secciones a traves del agujero de paso. ComoAlternatively, it is conceivable to provide the lower end zone of the two lateral longitudinal supports, respectively, with an external thread. In this case, it is advantageous for the lower end areas of the two longitudinal supports to be received, respectively, in a passage hole configured in the transverse support, such that the outer thread extends through sections through the passage hole.

elementos de tension previa son adecuadas, en esta forma de realizacion, por ejemplo, tuercas tensoras, que reciben, respectivamente, la zona roscada, que se extiende a traves de los agujeros de paso, del soporte longitudinal asociado.Pre-tension elements are suitable, in this embodiment, for example, tension nuts, which receive, respectively, the threaded area, which extends through the through holes, the associated longitudinal support.

De manera alternativa a ello, la zona extrema inferior de los dos soportes longitudinales laterales puede presentar, respectivamente, una rosca exterior y puede estar alojada en un casquillo de gma conectado con el soporte. En este caso, el al menos un elemento tensor puede estar realizado como casquillo tensor, que presenta una rosca interior, que esta realizada complementaria de la rosca exterior del soporte longitudinal correspondiente. El elemento de tension previa configurado, por ejemplo, como casquillo tensor, se extiende a traves del agujero de paso configurado en el soporte transversal, de manera que la rosca interior del casquillo tensor recibe la rosca exterior del soporte longitudinal correspondiente.Alternatively, the lower end zone of the two lateral longitudinal supports can have, respectively, an external thread and can be housed in a gma bushing connected to the support. In this case, the at least one tensioning element can be made as a tensioning bush, which has an internal thread, which is made complementary to the external thread of the corresponding longitudinal support. The pre-tension element configured, for example, as a tension bushing, extends through the passage hole configured in the transverse support, so that the internal thread of the tension bushing receives the external thread of the corresponding longitudinal support.

En un desarrollo preferido de la ultima forma de realizacion mencionada, esta previsto que la rosca exterior este realizada en la zona extrema inferior de los dos soportes longitudinales laterales y la rosca interior del casquillo tensor este realizada, respectivamente, como rosca a la izquierda, estando previsto al menos un elemento de seguridad para impedir una manipulacion imprevista del casquillo tensor. Por ejemplo, es concebible que el al menos un elemento de seguridad este realizado como tornillo cilmdrico con una rosca a la derecha, en el que la rosca a la derecha del elemento de seguridad realizado como tornillo cilmdrico esta dispuesta coaxialmente al casquillo tensor y engrane en una rosca interior, que esta configurada en un taladro realizado en la zona extrema inferior de los soportes longitudinales laterales.In a preferred development of the last mentioned embodiment, it is provided that the outer thread is made in the lower end zone of the two lateral longitudinal supports and the inner thread of the tension bushing is made, respectively, as a thread on the left, being at least one safety element provided to prevent unforeseen manipulation of the tension bushing. For example, it is conceivable that the at least one safety element is made as a cylindrical screw with a right hand thread, in which the thread to the right of the security element made as a cylindrical screw is arranged coaxially to the tensioning bush and engages in an internal thread, which is configured in a hole made in the lower end area of the lateral longitudinal supports.

Todas las formas de realizacion descritas anteriormente tienen en comun que solamente a traves de la manipulacion del al menos un elemento de tension previa se puede ajustar la tension previa vertical de la instalacion del resorte de apoyo, de manera que para la manipulacion del elemento de tension previa solamente es suficiente una unica herramienta, y en el que a tal fin es suficiente un acceso limitado a los componentes del dispositivo de apoyo, en particular al menos a un elemento de tension previa.All of the embodiments described above have in common that only through the manipulation of the at least one pre-tension element can the vertical pre-tension of the support spring installation be adjusted, so that for the manipulation of the tension element only one single tool is sufficient, and in which limited access to the components of the support device, in particular at least one element of pre-tension, is sufficient for this purpose.

En un desarrollo ventajoso de la solucion segun la invencion esta previsto que al menos a un elemento de tension previa este asociado un seguro para impedir una manipulacion imprevista del elemento de tension previa. En particular, el seguro sirve para impedir un desprendimiento o aflojamiento involuntario de la union entre el al menos un elemento de tension previa y el soporte longitudinal lateral correspondiente, lo que se puede realizar especialmente a traves de influencias exteriores, por ejemplo oscilaciones (vibraciones), corrosion y deformacion.In an advantageous development of the solution according to the invention, it is provided that at least one prior tension element is associated with insurance to prevent unforeseen manipulation of the previous tension element. In particular, the insurance serves to prevent an involuntary detachment or loosening of the joint between the at least one pre-tension element and the corresponding lateral longitudinal support, which can be done especially through external influences, for example oscillations (vibrations) , corrosion and deformation.

A traves de la prevision de un seguro de este tipo se puede impedir de manera ventajosa que a traves de influencias externas, especialmente en el caso de cargas dinamicas, se modifica una distancia vertical ajustada a traves del al menos un elemento de tension previa entre el soporte transversal y la barra de acoplamiento. En funcion del tipo de elemento de tension previa que se emplea, el seguro puede adoptar diferentes formas de realizacion. Si se emplea, por ejemplo, una tuerca de tornillo (tuerca tensora) como elemento de tension previa, entonces puede servir un adhesivo, un inserto de plastico en la tuerca de tornillo o un seguro de alambre como seguro de tornillo. En cambio, si por ejemplo, un tornillo tensor (tornillo cilmdrico) sirve como elemento de tension previa, entonces se puede realizar el seguro como inserto roscado en la zona en forma de casquillo de los soportes longitudinales.Through the provision of insurance of this type it can be advantageously prevented that through external influences, especially in the case of dynamic loads, an adjusted vertical distance is modified through at least one element of prior tension between the cross support and tie rod. Depending on the type of pre-tension element used, the insurance can adopt different forms of realization. If, for example, a screw nut (tension nut) is used as a pre-tension element, then an adhesive, a plastic insert in the screw nut or a wire lock can be used as a screw lock. On the other hand, if, for example, a tensioning screw (cylindrical screw) serves as a pre-tension element, then the safety can be carried out as a threaded insert in the socket-shaped area of the longitudinal supports.

Segun la invencion, la instalacion de resorte de apoyo presenta al menos uno y con preferencia dos muelles de apoyo conectados con preferencia de forma desprendible con el soporte transversal, de manera que en este caso se trata de muelles de apoyo formados de un material elastomero. A traves de la utilizacion de al menos dos muelles de apoyo, que estan conectados paralelos entre sf, se pueden utilizar muelles de apoyo con una curva caractenstica mas blanda, con lo que se puede realizar un apoyo elastico muy bueno.According to the invention, the support spring installation has at least one and preferably two support springs, preferably detachably connected with the transverse support, so that in this case they are support springs formed of an elastomeric material. Through the use of at least two support springs, which are connected parallel to each other, support springs with a softer characteristic curve can be used, so that a very good elastic support can be performed.

A continuacion se describe en detalle con referencia a los dibujos adjuntos una forma de realizacion ejemplar del dispositivo de apoyo 50 segun la invencion. En particular, el dispositivo de apoyo 50 representado de forma ejemplar en los dibujos se emplea en una articulacion 2, que sirve para articular la barra de acoplamiento 1, por ejemplo, de un acoplamiento amortiguador medio en el lado frontal de un vagon no representado explfcitamente o bien en el bastidor inferior de un vagon no representado explfcitamente.An exemplary embodiment of the support device 50 according to the invention is described in detail below with reference to the accompanying drawings. In particular, the support device 50 exemplified in the drawings is used in an articulation 2, which serves to articulate the coupling bar 1, for example, of a medium damping coupling on the front side of a carriage not explicitly represented or in the lower frame of a carriage not explicitly represented.

En la forma de realizacion representada en los dibujos, la articulacion 2 presenta una instalacion de resorte de elastomero 10 para la amortiguacion de fuerzas de traccion y de choque transmitidas a traves de la barra de acoplamiento 1 sobre la articulacion 2. En este caso, esta previsto que la instalacion de resorte de elastomero 10 presenta una carcasa 11 abierta hacia una cabeza de acoplamiento no mostrada en los dibujos, en la que penetra coaxialmente la zona extrema trasera 3 (del lado del vagon) de la barra de acoplamiento 1 con una distancia radial desde la superficie periferica interior de la carcasa 11. La zona extrema trasera 3, es decir, en el lado del vagon, de la barra de acoplamiento 1 esta conectada a traves de la carcasa 11 con la articulacion 2. En la forma de realizacion representada en los dibujos, la conexion se realiza a traves de un pivote giratorio 16 que se extiende verticalmente, en el que la carcasa 11 esta conectada con la ayuda de elementos de cizallamiento y esta dispuesta pivotable horizontal y verticalmente en el soporte de cojinete 4 conectado fijamente con el vagon o bien con el bastidor inferior del vagon.In the embodiment represented in the drawings, the articulation 2 presents an elastomer spring installation 10 for the damping of tensile and shock forces transmitted through the coupling bar 1 on the articulation 2. In this case, this provided that the elastomer spring installation 10 has an open housing 11 towards a coupling head not shown in the drawings, in which the rear end zone 3 (on the side of the carriage) of the coupling bar 1 with a distance coaxially penetrates radial from the inner peripheral surface of the housing 11. The rear end zone 3, that is, on the side of the carriage, of the coupling bar 1 is connected through the housing 11 with the joint 2. In the embodiment represented in the drawings, the connection is made through a rotating pivot 16 that extends vertically, in which the housing 11 is connected with the help of shear elements and it is arranged pivotable horizontally and vertically in the bearing support 4 fixedly connected to the carriage or to the lower frame of the carriage.

Entre la superficie periferica interior de la carcasa 11 estan previstos unos anillos de resorte 13 pretensados de un material elastomero, que estan alineados verticalmente con sus planos medios y estan dispuestos unos detras de los oros a distancia mutua en la direccion longitudinal de la barra de acoplamiento 1, de manera que tanto la zona extrema trasera 3 de la barra de acoplamiento 1 como tambien el lado interior de la carcasa 11 presentan cordones anulares 14, 15 circundantes dirigidos entre sf Estos cordones anulares 14, 15 estan disenados de tal forma que los anillos elasticos 13, respectivamente, son retenidos, respectivamente, en espacios intermedios entre dos cordones anulares 14, 15 vecinos frente a la zona extrema trasera 3 de la barra de acoplamiento 1 y la carcasa 11. Puesto que cada anillo elastico 13 se apoya directamente tanto en la superficie periferica de la barra de acoplamiento 1 como tambien en la superficie periferica interior 12 de la carcasa 11, de manera que en el estado no cargado con respecto a fuerzas de traccion y de choque de la instalacion de resorte de elastomero 10, los cordones anulares 14 de la barra de acoplamiento 1 estan alineados con los cordones anulares 15 asociados de la carcasa 11, se consigue que, por una parte, se posibilite un movimiento cardanico de la barra de acoplamiento 1 y que, por otra parte, puedan ser recibidas y absorbidas fuerzas de traccion y de presion hasta una magnitud fija definida.Between the inner peripheral surface of the housing 11, prestressed spring rings 13 of an elastomeric material are provided, which are vertically aligned with their median planes and are arranged behind the rings at a mutual distance in the longitudinal direction of the coupling bar. 1, so that both the rear end zone 3 of the coupling bar 1 and also the inner side of the housing 11 have surrounding annular cords 14, 15 directed towards each other. These annular cords 14, 15 are designed such that the rings elastics 13, respectively, are retained, respectively, in intermediate spaces between two annular cords 14, 15 neighbors facing the rear end zone 3 of the tie bar 1 and the housing 11. Since each elastic ring 13 rests directly on both the peripheral surface of the coupling bar 1 as well as the inner peripheral surface 12 of the housing 11, so that in the unloaded state with respect to tensile and shock forces of the elastomer spring installation 10, the annular cords 14 of the coupling bar 1 are aligned with the associated annular cords 15 of the housing 11, it is achieved that, on the one hand, a cardanic movement of the coupling bar 1 is possible and, on the other hand, traction and pressure forces can be received and absorbed to a defined fixed magnitude.

Como ya se ha mencionado, la carcasa 11 de la instalacion de resorte de elastomero 10 esta conectada con la articulacion 2 con la ayuda de al menos un elemento de cizallamiento 8. En la forma de realizacion preferida mostrada en los dibujos, la articulacion 2 presenta un pivote de giro superior 16 y un pivote de giro inferior que se extienden verticalmente, en el que esta conectada, respectivamente, la carcasa 11 con la ayuda de un elemento de cizallamiento 8 y esta articulado en el soporte de cojinete 4 conectado fijamente con el vagon o bien con el bastidor inferior del vagon de forma pivotable horizontal y verticalmente. De manera preferida, en este caso esta previsto que la fuerza de reaccion de los elementos de cizallamiento 8 sea mayor que el importe de la fuerza, que puede transmitir la instalacion de resorte de elastomero 10 a traves de la deformacion regenerativa de los anillos de resorteAs already mentioned, the housing 11 of the elastomer spring installation 10 is connected to the joint 2 with the help of at least one shear element 8. In the preferred embodiment shown in the drawings, the joint 2 has a pivot of upper rotation 16 and a pivot of lower rotation that extend vertically, in which the housing 11 is connected respectively with the aid of a shearing element 8 and is articulated in the bearing support 4 fixedly connected with the wagon or with the bottom frame of the wagon pivotable horizontally and vertically. Preferably, in this case it is provided that the reaction force of the shearing elements 8 is greater than the amount of force, which the elastomer spring installation 10 can transmit through the regenerative deformation of the spring rings

La carcasa 11 de la instalacion de resorte de elastomero 10 esta configurada dividida de manera preferida y esta constituida de una cascara superior y una cascara inferior de la carcasa 11a. Esta forma de realizacion garantiza un montaje especialmente sencillo de la instalacion de resorte 10. Por lo demas, de este modo se puede ajustar de una manera especialmente sencilla la tension previa de la instalacion de resorte de elastomero 10 en direccion longitudinal de la barra de acoplamiento 1. Pero a tal fin tambien sena concebible que la zona extrema trasera 3 de la barra de acoplamiento 1 presente un collar (no representado explfcitamente), contra el que se apoya, por una parte, un anillo de tension previa (no representado) con su lado trasero y, por otra parte, el anillo de resorte 13 mas proximo a la abertura de la carcasa 11 con su lado delantero, de manera que el anillo de tension previa pretensa los anillos de resorte 13 en el estado no cargado de la instalacion de resorte de elastomero 10 en la direccion longitudinal de la barra de acoplamiento 1.The housing 11 of the elastomer spring installation 10 is preferably divided and is constituted of an upper shell and a lower shell of the housing 11a. This embodiment guarantees an especially simple assembly of the spring installation 10. Moreover, in this way the previous tension of the elastomer spring installation 10 in the longitudinal direction of the coupling bar can be adjusted in a particularly simple way. 1. But for this purpose it is also conceivable that the rear end zone 3 of the coupling bar 1 has a collar (not explicitly shown), against which, on the one hand, a pre-tension ring (not shown) is supported. its rear side and, on the other hand, the spring ring 13 closest to the opening of the housing 11 with its front side, so that the pre-tension ring presses the spring rings 13 in the unloaded state of the installation of elastomer spring 10 in the longitudinal direction of the coupling rod 1.

El anclaje 2 posibilita una articulacion horizontal y vertical asf como un giro axial de la barra de acoplamiento 1. De esta manera, la barra de acoplamiento 1 puede realizar, por ejemplo, movimientos de articulacion con relacion al vagon o bien al bastidor inferior del vagon, que aparecen especialmente durante una marcha en curva de una composicion de trenes. Ademas, la barra de acoplamiento 1 puede seguir desviaciones verticales, por ejemplo para la compensacion de diferencias de altura entre dos vagones a acoplar.The anchor 2 allows a horizontal and vertical articulation as well as an axial rotation of the coupling bar 1. In this way, the coupling bar 1 can, for example, perform articulation movements in relation to the carriage or to the lower frame of the carriage , which appear especially during a curved march of a train composition. In addition, the coupling bar 1 can follow vertical deviations, for example for the compensation of height differences between two wagons to be coupled.

La instalacion de resorte de elastomero 10 con los anillos de resorte 13 formaos con preferencia de un material elastomero sirve para la amortiguacion de las fuerzas de traccion y de choque transmitidas en la operacion de marcha normal desde la barra de acoplamiento 1 hasta la articulacion 2. En general, la instalacion de resorte de elastomero 10 prevista en la articulacion 2 esta disenada para permitir los angulos de articulacion requeridos operativamente de la barra de acoplamiento 1 en la direccion vertical de aproximadamente + 6° en la direccion horizontal de aproximadamente + 15°.The elastomer spring installation 10 with the spring rings 13 preferably formed of an elastomeric material is used for damping the tensile and shock forces transmitted in normal running operation from the coupling bar 1 to the joint 2. In general, the elastomer spring installation 10 provided in the joint 2 is designed to allow the operating angles of the coupling rod 1 operatively required in the vertical direction of approximately + 6 ° in the horizontal direction of approximately + 15 °.

La articulacion 2 representada de forma ejemplar en los dibujos esta equipada, ademas, con un dispositivo de apoyo 50. El dispositivo de apoyo 50 sirve para el apoyo vertical de la barra de acoplamiento 1 articulada, entre otros, en direccion vertical pivotable sobre una articulacion 2 en el vagon o bien en el bastidor inferior del vagon. Como ya se ha indicado en la introduccion de la descripcion, un apoyo de este tipo es especialmente necesario en direccion vertical, para posibilitar un acoplamiento reefecto de dos vagones vecinos. A tal fin, hay que procurar que durante el proceso de acoplamiento la barra de acoplamiento 1 este siempre en el plano medio longitudinal horizontal.The articulation 2 exemplified in the drawings is also equipped with a support device 50. The support device 50 serves for the vertical support of the articulated coupling bar 1, among others, in a pivotable vertical direction on a joint 2 in the car or in the lower frame of the car. As already indicated in the introduction of the description, such a support is especially necessary in the vertical direction, to enable a perfect coupling of two neighboring wagons. To this end, it must be ensured that during the coupling process the coupling bar 1 is always in the horizontal longitudinal median plane.

Con esta finalidad, el dispositivo de apoyo 50 representado en los dibujos presenta una instalacion de resorte de apoyo 51 que esta en contacto con la barra de acoplamiento 1 asf como un soporte de fijacion, a traves del cual la instalacion de resorte de apoyo 51 esta conectada al menos indirectamente con el vagon o bien el batidor inferior del vagon. En particular, el soporte de fijacion comprende un soporte transversal inferior 54, que sirve para el apoyo de la instalacion de resorte de apoyo 51. Adicionalmente al soporte transversal inferior 54 se emplean dos soportes longitudinales laterales 55, 56 que se extienden verticales, sobre los que el soporte transversal 54 esta conectado con el vagon o bien el bastidor inferior del vagon.For this purpose, the support device 50 shown in the drawings presents a support spring installation 51 that is in contact with the coupling bar 1 as well as a fixing support, through which the support spring installation 51 is connected at least indirectly with the car or the lower car beater. In particular, the fixing support comprises a lower transverse support 54, which serves to support the support spring installation 51. In addition to the lower transverse support 54 two lateral longitudinal supports 55, 56 extending vertically, are used on the that the transverse support 54 is connected to the carriage or the lower carriage frame.

Como se puede deducir especialmente, por ejemplo, a partir de las representaciones en la figura 1 y en la figura 2, los dos soportes longitudinales laterales 55, 56 del soporte de fijacion no estan conectados directamente con el vagon o bien el batidor inferior del vagon. En su lugar, en la forma de realizacion representada, las zonas extremas superiores respectivas de los soportes longitudinales laterales 55, 56 estan conectadas con la carcasa 11 en la articulacion 2. Como ya se ha indicado, la carcasa 11 de la articulacion 2 esta conectada sobre los polvotes de giro superior e inferior 16 con el soporte de cojinete 4 conectado fijamente en el vagon o bien en el batidor inferior del vagon.As can be deduced especially, for example, from the representations in Figure 1 and Figure 2, the two lateral longitudinal supports 55, 56 of the fixing support are not directly connected to the carriage or the lower beater of the carriage . Instead, in the embodiment shown, the respective upper end zones of the lateral longitudinal supports 55, 56 are connected to the housing 11 in the joint 2. As already indicated, the housing 11 of the joint 2 is connected on the upper and lower turning dusts 16 with the bearing support 4 fixedly connected in the carriage or in the lower carriage of the carriage.

En particular, en la forma de realizacion representada, las zonas extremas superiores respectivas de los soportes longitudinales laterales 55, 56 estan conectadas sobre una conexion roscada 57 con la carcasa 11. La union roscada 57 esta realizada con preferencia de tal forma que esta pierde su funcion de union cuando se excede la carga operativa de la instalacion de resorte de elastomero 10 prevista en la articulacion 2. De esta manera, en un caso de impacto, por ejemplo en el caso de un choque el vehnculo sobre un obstaculo, se desprende la union entre el soporte de fijacion del dispositivo de apoyo (50) y el vagon o bien el bastidor inferior el vagon, de manera que el dispositivo de apoyo 50 no impide un movimiento longitudinal de la barra de acoplamiento 1 en la direccion del vagon. En este contexto sena concebible que para la realizacion de la union atornillada 57 se utilizase al menos un tornillo de cizallamiento / desgarro, que pierde su funcion de union, es decir, que se cizalla o bien se desgarra cuando se excede la carga operativa de la instalacion de resorte de elastomero 10 prevista en la articulacion 2.In particular, in the embodiment shown, the respective upper end areas of the lateral longitudinal supports 55, 56 are connected on a threaded connection 57 with the housing 11. The threaded joint 57 is preferably made such that it loses its function of union when the operative load of the elastomer spring installation 10 provided in the joint 2 is exceeded. In this way, in an impact case, for example in the case of a crash the vehicle on an obstacle, the union between the fixing support of the support device (50) and the carriage or the lower frame of the carriage, so that the support device 50 does not prevent a longitudinal movement of the coupling bar 1 in the direction of the carriage. In this context it will be conceivable that at least one shear / tear screw was used for the realization of the screwed joint 57, which loses its joint function, that is, that it is sheared or torn when the operating load of the elastomer spring installation 10 provided in the joint 2.

Por otra parte, tambien sena concebible utilizar como union atornillada 57 al menos un tornillo, que es recibido en un alojamiento de tal manera que en el caso de que se exceda la carga operativa de la instalacion de resorte de elastomero 10 previsto en la articulacion 2, el al menos un tornillo se mueve fuera del alojamiento, por lo que se desprende la union entre el soporte de fijacion del dispositivo de apoyo 50 y el vagon o bien la parte inferior del vagon.On the other hand, it is also conceivable to use at least one screw as a screwed joint 57, which is received in a housing such that in the event that the operating load of the elastomer spring installation 10 provided in the joint 2 is exceeded , the at least one screw moves out of the housing, whereby the connection between the fixing support of the support device 50 and the carriage or the lower part of the carriage is detached.

En el dispositivo de apoyo 50 se trata de un apoyo configurado elastico, en el que la instalacion de resorte de apoyo 51 presenta al menos un muelle de apoyo 52, 53 - exactamente dos en la forma de realizacion representada -. Los dos muelles de apoyo 52, 53 estan conectados con el soporte transversal 54 y son presionados con una cierta tension previa desde abajo en la direccion vertical hacia la barra de acoplamiento 1. La tension previa, con la que los muelles de apoyo 52, 53 presionan contra la barra de acoplamiento 1, es regulable por medio de la variacion de la distancia vertical entre el soporte transversal 54 y la barra de acoplamiento 1 y debena estar seleccionada para que en un estado de reposo de la barra de acoplamiento 1, es decir, cuando no inciden fuerza dinamicas en direccion vertical en la barra de acoplamiento 1, la barra de acoplamiento 1 se encuentra en la posicion media horizontal.In the support device 50 it is an elastic configured support, in which the support spring installation 51 has at least one support spring 52, 53 - exactly two in the embodiment shown -. The two support springs 52, 53 are connected to the transverse support 54 and are pressed with a certain pre-tension from below in the vertical direction towards the coupling bar 1. The pre-tension, with which the support springs 52, 53 they press against the coupling bar 1, it is adjustable by means of the variation of the vertical distance between the transverse support 54 and the coupling bar 1 and must be selected so that in a resting state of the coupling bar 1, ie , when dynamic forces do not impact in the vertical direction on the coupling bar 1, the coupling bar 1 is in the middle horizontal position.

Puesto que la distancia vertical entre el soporte transversal 54 y la barra de acoplamiento 1 se vana, se puede ajustar la inclinacion vertical de la barra de acoplamiento 1. Como ya se ha indicado, la barra de acoplamiento 1 debena estar en el estado no cargado en el plano horizontal para posibilitar un acoplamiento perfecto de dos vagones vecinos.Since the vertical distance between the transverse support 54 and the coupling rod 1 is widened, the vertical inclination of the coupling rod 1 can be adjusted. As already indicated, the coupling rod 1 must be in the unloaded state. in the horizontal plane to enable a perfect coupling of two neighboring wagons.

El empleo de los muelles de apoyo 52, 53, que estan formaos de un material elastomero, tiene, sin embargo, la consecuencia de que despues de un intervalo de tiempo determinado debe reajustarse el apoyo, puesto que cuando los muelles de apoyo 52, 53 estan bajo tension en el transcurso del tiempo puede tener lugar un asentamiento del material elastomero, es decir, que la curva caractenstica de resorte de los muelles de apoyo 52, 53 se aplana en el transcurso del tiempo, lo que pude tener como consecuencia una inclinacion de la barra de acoplamiento 1. De esta manera, debe reajustarse una barra de acoplamiento 1 ajustada originalmente ya en el plano medio longitudinal horizontal despues de un cierto tiempo. Con otras palabras, hay que procurar que se pueda variar posteriormente la distancia vertical entre el soporte transversal 54 y la barra de acoplamiento 1.The use of the support springs 52, 53, which are formed of an elastomeric material, has, however, the consequence that after a certain period of time the support must be readjusted, since when the support springs 52, 53 they are under tension in the course of time a settling of the elastomeric material can take place, that is to say that the characteristic spring curve of the support springs 52, 53 flattens over the course of time, which could result in an inclination of the coupling rod 1. In this way, a coupling rod 1 originally set in the horizontal longitudinal median plane after a certain time must be readjusted. In other words, it must be ensured that the vertical distance between the transverse support 54 and the coupling bar 1 can be varied later.

Con esta finalidad, en la forma de realizacion representada en los dibujos del dispositivo de apoyo 50 segun la invencion se emplean unos elementos de tension previa, a traves de los cuales las zonas extremas inferiores 68, 69 de los dos soportes longitudinales laterales 55, 56 estan unidas, respectivamente, con el soporte transversal 54, de tal manera que se puede ajustar una distancia vertical entre el soporte transversal 54 y la barra de acoplamiento 1 y, por lo tanto, una tension previa vertical de la instalacion de resorte de apoyo 51.For this purpose, in the embodiment represented in the drawings of the support device 50 according to the invention, tension elements are used, through which the lower end zones 68, 69 of the two lateral longitudinal supports 55, 56 they are connected, respectively, with the transverse support 54, so that a vertical distance between the transverse support 54 and the coupling bar 1 and, therefore, a vertical pre-tension of the support spring installation 51 can be adjusted .

En particular y como se puede deducir espacialmente a partir de la representacion en la figura 7, se ofrece a tal fin que las zonas extremas inferiores 68, 69 de los dos soportes longitudinales laterales 55, 56 presenten, respectivamente, una rosca exterior y esten alojadas, respectivamente, en un casquillo tensor 61 conectado con el soporte transversal 54, de manera que el casquillo tensor 61 sirve como elemento de tension previa y presenta una rosca interior configurada complementaria de la rosca exterior del soporte longitudinal 55, 56 correspondiente. Ademas, a partir de la representacion en la figura 7 se puede deducir que en el ejemplo de realizacion representado los casquillos tensores 61 se extienden, respectivamente a traves de un orificio de paso 60 configurado en el soporte transversal 54. Ademas, se puede reconocer que la rosca interior del casquillo tensor 61 recibe la rosca exterior del soporte longitudinal 55, 56 correspondiente.In particular and as can be deduced spatially from the representation in Figure 7, it is offered for this purpose that the lower end zones 68, 69 of the two lateral longitudinal supports 55, 56 respectively have an external thread and are housed , respectively, in a tension bushing 61 connected to the transverse support 54, so that the tension bushing 61 serves as a pre-tension element and has an internal thread configured complementary to the external thread of the corresponding longitudinal support 55, 56. Furthermore, from the representation in Figure 7 it can be deduced that in the exemplary embodiment shown, the tension bushes 61 extend, respectively, through a through hole 60 configured in the transverse support 54. In addition, it can be recognized that the inner thread of the tension bushing 61 receives the external thread of the corresponding longitudinal support 55, 56.

Para la regulacion de la tension previa vertical de la instalacion de resorte de apoyo 51 se enroscan, en el ejemplo de realizacion representado en los dibujos, los dos elementos de tension previa realizaos como casquillos tensores 61 adicionalmente en la zonas extremas 68, 69 correspondientes de los soportes longitudinales 55, 56, por lo que se reduce la distancia vertical entre el soporte transversal 54 y la barra de acoplamiento 1 y se eleva la tension previa de la instalacion de resorte de apoyo 51. De esta manera, se puede variar posteriormente la articulacion vertical de la barra de acoplamiento 1.For the regulation of the vertical pre-tension of the support spring installation 51, in the exemplary embodiment shown in the drawings, the two pre-tension elements made as tension bushes 61 additionally in the corresponding end zones 68, 69 of the longitudinal supports 55, 56, whereby the vertical distance between the transverse support 54 and the coupling bar 1 is reduced and the pre-tension of the support spring installation 51 is raised. In this way, it is possible to subsequently vary the vertical articulation of the coupling rod 1.

Para evitar que los casquillos tensores 61 empleados como elemento de tension previa en la forma de realizacion representada en los dibujos se puedan soltar o aflojan de forma imprevista, con lo que forzosamente se incremental la distancia vertical entre el soporte transversal 54 y la barra de acoplamiento 1 y se reducina la tension previa vertical de la instalacion de resorte de apoyo 51, la rosca exterior en la zona extrema inferior 68, 69 de los dos soportes longitudinales laterales 55, 56 y la rosca interior del casquillo tensor 61 estan realizadas, respectivamente, como rosca a la izquierda, estando previsto al menos un elemento de seguridad 67 para impedir una manipulacion imprevista del casquillo tensor 61.In order to prevent the tension bushes 61 used as a pre-tension element in the embodiment shown in the drawings from being released or loosened unexpectedly, thereby necessarily increasing the vertical distance between the transverse support 54 and the coupling bar 1 and the vertical pre-tension of the support spring installation 51, the outer thread in the lower end zone 68, 69 of the two lateral longitudinal supports 55, 56 and the inner thread of the tension bushing 61 are made, respectively, are reduced, respectively, as a thread on the left, at least one safety element 67 is provided to prevent unforeseen manipulation of the tension bushing 61.

Como se representa, el al menos un elemento de seguridad 67 esta realizado como tornillo cilmdrico con una rosca a la derecha, de manera que la rosca a la derecha del elemento de seguridad 67 realizado como tornillo cilmdrico esta dispuesta coaxialmente al casquillo tensor 61 y encaja en una rosca interior 58, que esta configurada en un taladro realizado en la zona extrema inferior 68, 69 de los soportes longitudinales laterales 55, 56.As shown, the at least one safety element 67 is made as a cylindrical screw with a thread on the right, so that the thread on the right of the security element 67 made as a cylindrical screw is coaxially arranged to the tension bushing 61 and fits in an inner thread 58, which is configured in a hole made in the lower end zone 68, 69 of the lateral longitudinal supports 55, 56.
