Description
BOGIE DE ANCHO VARIABLE MEJORADO CON EJES GIRATORIOS IMPROVED VARIABLE WIDTH BOGIE WITH ROTATING AXLES
CAMPO DE LA INVENCIÓNFIELD OF THE INVENTION
La invención se refiere a un bogie con medios para circular en vías de distinto ancho y más en particular a un bogie con ejes giratorios dotado de un dispositivo de cambio de ancho en cooperación con una instalación cambiadora dispuesta entre dos vías de distinto ancho.The invention relates to a bogie with means for driving on tracks of different widths and more particularly to a bogie with rotating shafts provided with a width change device in cooperation with a changing facility arranged between two tracks of different width.
ANTECEDENTESBACKGROUND
La solicitante de esta invención desarrolló hace varias décadas un sistema de cambio de ancho de vía, objeto de Ia patente ES 332.453, en respuesta a ia iniciativa de Renfe de convocar un concurso público de soluciones para evitar el transbordo de pasajeros en Ia frontera hispanofrancesa, operación obligada hasta entonces, debido al diferente ancho de las vías de Ia península ibérica (1668 mm) en relación con las europeas (1435 mm). Ese sistema implica, por un lado, Ia incorporación a las unidades ferroviarias de un dispositivo de traslación de las ruedas de sus ejes y, por otro lado, de una instalación cambiadora montada entre las vías de distinto ancho. La operación de cambio de Ia distancia entre ruedas se realiza de forma automática, sin intervención humana, al paso del tren sobre dicha instalación en cinco fases que se suceden de forma continua; en Ia primera de ellas, se liberan ¡as ruedas de sus cargas verticales; en Ia segunda, los conjuntos de ios ejes de las ruedas se liberan de un mecanismo de bloqueo lateral que las mantiene en su posición de rodaje; en Ia tercera, las ruedas, liberadas de su carga vertical y de su bloqueo lateral, entran en unas guías que, al avanzar el eje, las trasladan lateralmente hasta su nueva posición de rodaje, de acuerdo con el nuevo ancho de vía; en Ia cuarta y quinta fase, se vuelven a bloquear lateralmente ios conjuntos de rueda y se aplica de nuevo al eje su carga vertical, con Io que concluye Ia operación de cambio.
Tras esa innovación, que supuso un hito importante en Ia tecnología ferroviaria, Ia solicitante de esta invención ha llevado a cabo distintos desarrollos para aplicar el sistema a distintas estructuras ferroviarias: ejes independientes, bogies, bogies de mercancía y bogies motores y, entre ellos, el descrito en Ia patente ES 2 130 039 "Conjunto de eje ferroviario dotado de cambio automático de ancho de vía y adaptable a bogies convencionales de mercancías", que puede ser incorporado en los bogies convencionales de mercancías en sustitución de los ejes montados de ancho fijo, sin que se requiera una modificación sustancial de los mismos. El eje integra dos conjuntos de rodadura independientes (rueda con eje corto o semieje y dos cojinetes), realizándose el cambio de ancho entre ruedas por desplazamiento transversal simultáneo de ¡as dos rodaduras de manera similar a Ia utilizada en los trenes TALGO aunque, en lugar de incluir dispositivos de enclavamiento en los dos cojinetes de cada rodadura, solo incorporan el dispositivo de enclavamiento en el cojinete interior.The applicant for this invention developed several decades ago a system of change of track width, object of the patent ES 332.453, in response to the initiative of Renfe to call a public contest of solutions to avoid the transhipment of passengers in the Spanish-French border, operation forced until then, due to the different width of the tracks of the Iberian Peninsula (1668 mm) in relation to the European (1435 mm). This system implies, on the one hand, the incorporation into the railway units of a device for transferring the wheels of its axles and, on the other hand, of a changing facility mounted between the tracks of different widths. The operation of changing the wheelbase is carried out automatically, without human intervention, when the train passes over said installation in five phases that follow each other continuously; in the first of them, the wheels of their vertical loads are released; in the second, the wheel axle assemblies are released from a lateral locking mechanism that keeps them in their rolling position; in the third, the wheels, freed from their vertical load and from their lateral blockage, enter guides that, when advancing the axle, move them laterally to their new rolling position, in accordance with the new track width; in the fourth and fifth phase, the wheel assemblies are laterally blocked again and their vertical load is applied again to the axle, which concludes the changeover operation. After this innovation, which was an important milestone in rail technology, the applicant for this invention has carried out different developments to apply the system to different rail structures: independent axes, bogies, merchandise bogies and motor bogies and, among them, the one described in the patent ES 2 130 039 "Rail axle assembly equipped with automatic track width change and adaptable to conventional merchandise bogies", which can be incorporated in conventional merchandise bogies instead of fixed-mounted axles , without requiring a substantial modification thereof. The axle integrates two independent rolling assemblies (wheel with short or semi-axle axle and two bearings), with the change in width between wheels by simultaneous transverse displacement of the two bearings similar to that used in the TALGO trains although, instead if interlocking devices are included in the two bearings of each race, they only incorporate the interlocking device in the inner bearing.
Estructuralmente, el conjunto de eje comprende un bastidor de eje sobre el que van montados los dos conjuntos de rodadura y sus sistemas de enclavamiento, un dispositivo de unión entre rodaduras, dos armaduras de traslación de las zapatas de freno, un sistema de continuidad eléctrica entre las ruedas o un sistema de shuntaje eléctrico y un dispositivo de detección de cojinetes interiores calientes.Structurally, the axle assembly comprises an axle frame on which the two rolling assemblies and their interlocking systems are mounted, a joint between wheels, two brakes of the brake shoes, an electrical continuity system between the wheels or an electric shuntaje system and a hot inner bearing detection device.
Si bien Ia tecnología descrita en Ia patente ES 2 130 039 ha facilitado Ia adaptación de bogies tradicionales de mercancías a anchos de vía variable, la industria ferroviaria demanda constantemente nuevas soluciones para afrontar las distintas problemáticas planteadas por Ia adaptación de los vagones ferroviarios de mercancías a vías de distinto ancho. En este sentido, hay que señalar que, en particular en España, la implantación dei ancho europeo en Ia red de alta velocidad ha multiplicado las necesidades tecnológicas relacionadas con el cambio de ancho de vía. La presente invención está orientada a ía satisfacción de esa demanda.
SUMARIO DE LA INVENCIÓNAlthough the technology described in the patent ES 2 130 039 has facilitated the adaptation of traditional merchandise bogies to widths of variable track, the railway industry constantly demands new solutions to face the different problems posed by the adaptation of the rail freight wagons to tracks of different width. In this regard, it should be noted that, particularly in Spain, the implementation of European width in the high-speed network has multiplied the technological needs related to the change in track width.

Las piezas-soporte 10 también incluyen un bastidor lateral con unos patines de apoyo y deslizamiento 16 en Ia instalación cambiadora, a cuyo efecto llevan una guías de nylon 17 y un collar central que sirve de apoyo al extremo del eje 2, revestido por el casquillo 13, durante el paso por la instalación cambiadora a través de un casquillo semicircular 14 unido a dicho collar central que, preferentemente, está fabricado en bronce. Como veremos más adelante, durante Ia operación de cambio de ancho de vía, el bogie se apoya y desliza sobre esos patines 16 quedando descargadas las ruedas 1.
Como bien comprenderá eí experto en ¡a materia, esa configuración del bastidor latera! de ías piezas soporte viene determinada, al menos en parte, porThe central part of the axle 2, on which the wheels 1 are placed in the positions corresponding to the two track widths by means of the coupling device that we have described as well as a track change device, has a diameter greater than that of its parts extreme In the transition zone between the two widths, the bushing 8 'is provided, which serves as a stop for the displacement of the bushing 3. At the ends of the shaft 2 there is a bushing 13 together with a cover 15 fixed to the shaft 2 by means of screws that serve protection element thereof during the operation of change of track width as well as stop of the bearings 12. The support-pieces 10 also include a side frame with support and sliding skates 16 in the changing facility, to which effect they lead a nylon guides 17 and a central collar that supports the end of the shaft 2, covered by the bushing 13, during the passage through the changing facility through a semicircular bushing 14 attached to said central collar which, preferably, is manufactured in bronze As we will see later, during the operation of change of track width, the bogie rests and slides on those skates 16, the wheels 1 being unloaded. As you will well understand the subject matter expert, that configuration of the frame will be late! of the support pieces is determined, at least in part, by
Ia disposición de los carriles guía de deslizamiento y centrado 19, Si estos tuvieran otra disposición, Ia configuración del bastidor lateral quedaría lógicamente modificada de manera que cumpliera las funciones señaladas.The arrangement of the sliding and centering guide rails 19, If these had another arrangement, the configuration of the lateral frame would be logically modified so as to fulfill the indicated functions.
El cerrojo 22 está constituido por dos vastagos verticales unidos entre sí por un puente hueco diseñado para que se introduzca por él Ia cabeza de Ia guía de desenclavamiento 24 en forma de doble T de la instalación cambiadora de cambio de ancho de vía. Para evitar un enclavamiento/desenclavamiento accidental, el cerrojo incluye muelles de seguridad 28 pretensados para evitar desplazamientos verticales indeseados de! cerrojo 22 cuando no está en contacto con Ia guía de desenclavamiento 24.The bolt 22 is constituted by two vertical rods connected to each other by a hollow bridge designed so that the head of the unlocking guide 24 in the form of a double T of the track-change changer installation is introduced. To prevent accidental interlocking / unlocking, the bolt includes prestressed safety springs 28 to prevent unwanted vertical displacements of! bolt 22 when not in contact with the unlocking guide 24.
En las realizaciones mostradas en las figuras, el dispositivo de encerrojamiento cuenta con un elemento adicional de seguridad formado por el cerrojillo 25, unido al cerrojo 22 y desplazable lateralmente venciendo Ia fuerza del muelle 21 , y un elemento retenedor 26 unido al elemento tubular 29. Cuando el muelle 21 está en reposo, el cerrojillo 25 está en contacto con e! elemento retenedor 26 impidiendo el desplazamiento vertical del cerrojo 22. Para que ese desplazamiento sea posible es necesario aplicar una fuerza en el muelle 21 que desplace lateralmente el cerrojillo 25 e impida su retención por el elemento retenedor 26.In the embodiments shown in the figures, the locking device has an additional safety element formed by the bolt 25, attached to the bolt 22 and laterally movable overcoming the force of the spring 21, and a retaining element 26 attached to the tubular element 29. When the spring 21 is at rest, the bolt 25 is in contact with e! retaining element 26 preventing vertical displacement of the bolt 22. In order for this displacement to be possible it is necessary to apply a force on the spring 21 that laterally displaces the bolt 25 and prevents its retention by the retaining element 26.
Se describe seguidamente el proceso de cambio de ancho de vía al paso por Ia mencionada instalación cambiadora cuyos componentes fundamentales son los siguientes: - Extremos de los carriles 31 de Ia vía de mayor ancho.The process of changing the width of the track as it passes through the aforementioned changing facility whose fundamental components are the following are described: - Ends of the lanes 31 of the widest track.
- Extremos de los carriles 32 de Ia vía de menor ancho.- Ends of lanes 32 of the path of smaller width.
- Carriles guía de deslizamiento y centrado 19.- Sliding and centering guide rails 19.
- Guías 24 de desenclavamiento y enclavamiento de los cerrojos 22.- Guide 24 for unlocking and locking the bolts 22.
- Guías 27 de traslación de las ruedas 1. La instalación cambiadora es bidireccíonal, realizándose en un sentido el cambio de Ia vía ancha a Ia estrecha, mientras que en el sentido opuesto se lleva a cabo el cambio inverso.
El proceso de cambio de ancho de vía de un vagón que llega a Ia instalación por Ia vía ancha se efectúa de la forma siguiente.- Wheel transfer guides 27 1. The changer installation is bidirectional, the change from the wide to the narrow track being made in one direction, while in the opposite direction the reverse change is carried out. The process of changing the track width of a car that arrives at the installation via the wide track is carried out as follows.
Primera faseFirst phase
Las ruedas 1 se encuentran sobre los carriles 31 de la vía de mayor ancho (Fig. 1 A y Fig. 2A).Wheels 1 are located on rails 31 of the widest track (Fig. 1 A and Fig. 2A).
Segunda faseSecond stage
Cuando las ruedas 1 alcanzan Ia zona descendente del extremo de los carriles 31 se inicia un descenso paulatino del bogie hasta que los patines de deslizamiento 16 toman contacto con los carriles guía de deslizamiento y centrado 19. A partir de este momento, las ruedas 1 se descargan, permaneciendo así durante todo el proceso de cambio, hasta tomar contacto con los carriles 32 de menor ancho al final del mismo (Fig. 1 B y Fig. 2B).When the wheels 1 reach the descending zone of the end of the rails 31, a gradual descent of the bogie begins until the sliding skates 16 make contact with the sliding and centered guide rails 19. From this moment on, the wheels 1 are unload, thus remaining throughout the entire change process, until contacting the 32 smaller rails at the end of it (Fig. 1 B and Fig. 2B).
Tercera faseThird phase
Una vez apoyado y centrado el eje 2 sobre las guías de deslizamiento y centrado 19, las cabezas del extremo de ías guías de desenclavamíento 24 se introducen en el puente del cerrojo 22 y dado el perfil descendente de esta guía se vence Ia fuerza de los muelles verticales 28 y se obliga a bajar ios cerrojos 22, dejando desenclavadas las guías de encerrojamiento 18, quedando pues libres de moverse lateralmente y con ellas las ruedas 1. En Ia realización preferente de Ia invención en Ia que eí dispositivo de encerrojamiento incluye como elemento adicional de seguridad el cerrojillo 25, en esta fase también hay que actuar sobre ei muelle horizontal 21 , para desplazar lateralmente ei cerrojillo 25 evitando con ello que el retenedor 26 impida ía bajada del cerrojo 22. A ese efecto se configura uno de los lados de Ia cabeza de las guías de desenciavamiento 24 de Ia instalación cambiadora, con forma de doble T, con una anchura progresivamente variable desde ios extremos al centro -menor en los extremos que en el centro- como puede apreciarse observando comparativamente las figuras 1B y 1C, con Io que Ia guía 24 sirve de elemento accionador de! muelle horizontal 21 que controla el desplazamiento lateral del cerrojillo 25 (Fig. 1C y Fig. 2C).
Por su parte, las guías 27 provocan el desplazamiento lateral del dispositivo de acoplamiento de las ruedas 1 al eje 2 hasta que alcanzan Ia posición correspondiente a Ia vía de ancho estrecho 32.Once the axis 2 is supported and centered on the sliding and centering guides 19, the heads of the end of the unlocking guides 24 are introduced into the bridge of the bolt 22 and given the descending profile of this guide the force of the springs is overcome verticals 28 and the bolts 22 are forced down, leaving the locking guides 18 unlocked, thus freeing the wheels to move laterally and with them 1. In the preferred embodiment of the invention in which the locking device includes as an additional element of safety the bolt 25, in this phase it is also necessary to act on the horizontal spring 21, to move the bolt 25 laterally, thereby preventing the retainer 26 from preventing the bolt from being lowered 22. To this end, one of the sides of the Ia is configured. head of the removal guides 24 of the double T-shaped changing facility, with a progressively variable width from the ends to the center or - lower at the ends than in the center - as can be seen by comparing figures 1B and 1C comparatively, so that the guide 24 serves as an actuator element of! horizontal spring 21 that controls the lateral movement of the bolt 25 (Fig. 1C and Fig. 2C). On the other hand, the guides 27 cause the lateral displacement of the coupling device of the wheels 1 to the axle 2 until they reach the position corresponding to the narrow gauge track 32.
Cuarta fase El perfil ascendente de Ia guía 24 obliga al cerrojo 22 a ascender enclavando Ia guía 18 en Ia nueva posición.Fourth phase The ascending profile of guide 24 forces bolt 22 to rise by locking guide 18 in the new position.
En Ia realización preferente de Ia invención que incluye el cerrojillo 25 y Ia guía 24 con uno de los lados de Ia cabeza de ancho variable, ai final de Ia fase el muelle 21 se queda en reposo y el cerrojillo 25 queda retenido por el elemento retenedor 26 (Fig. 1 D y Fig. 2D). Quinta faseIn the preferred embodiment of the invention that includes the bolt 25 and the guide 24 with one of the sides of the head of variable width, at the end of the phase the spring 21 remains at rest and the bolt 25 is retained by the retaining element 26 (Fig. 1 D and Fig. 2D). Fifth phase
Al llegar las ruedas 1 a los carriles 32 los patines 16 dejan de apoyarse en sus guías de deslizamientos 19, concluyéndose Ia operación de cambio de ancho de vía (Fig, 1 E y Fig. 2E). Aunque Ia presente invención se ha descrito enteramente en conexión con realizaciones preferidas, es evidente que se pueden introducir aquellas modificaciones dentro de su alcance, no considerando éste como limitado por las anteriores realizaciones, sino por el contenido de las reivindicaciones siguientes.
When the wheels 1 reach the rails 32, the skates 16 cease to rest on their slide guides 19, the track width change operation being concluded (Fig, 1 E and Fig. 2E).
