Más concretamente, la presente invención se refiere a un conjunto ferroviario de adaptación a diferentes anchos de vía que comprende pares de ruedas conectadas por un eje fijo, donde cada rueda comprende un sistema, que por su morfología, permite el giro de la rueda como su desplazamiento axial una vez entre en el cambio de ancho y dónde un sistema de transmisión fijo exteriormente y con capacidad de desplazamiento axial en su parte interior transmite el par de giro sincronizado entre ejes de cada una de las ruedas del par de ruedas del conjunto ferroviario. More specifically, the present invention relates to a railway assembly for adaptation to different track widths comprising pairs of wheels connected by a fixed axle, where each wheel comprises a system, which by its morphology, allows the rotation of the wheel as its axial displacement once it enters the change in width and where an externally fixed transmission system with axial displacement capacity in its inner part transmits the synchronized torque between axles of each of the wheels of the pair of wheels of the railway assembly.
Antecedentes de la invención Background of the invention
Actualmente se conocen y se emplean una gran variedad de conjuntos ferroviarios para circular en vías de distinto ancho, así, han surgido carros como los descritos en ES2353415, de este mismo solicitante, que describe un bogie de ancho variable con un dispositivo de cambio de ancho de vía y dónde los pares de ruedas están conectados por un eje giratorio y no fijo y que incorpora en sus zonas exteriores piezas soporte de los muelles de suspensión de la plataforma sobre los que se montan los pares de ruedas. Currently, a wide variety of railway assemblies are known and used to drive on roads of different widths, thus, cars such as those described in ES2353415 have emerged, from this same applicant, which describes a variable-width bogie with a width change device of track and where the pairs of wheels are connected by a rotating and non-fixed axle and that incorporates in its outer areas support pieces of the suspension springs of the platform on which the pairs of wheels are mounted.
ES2151871 describe un bogie de rodadura de ancho variable autopropulsado, donde el bogie dispone al menos un eje fijo sin giro en el que se disponen de cajas de soporte que permite el movimiento del eje únicamente en sentido vertical y casquillos deslizantes portadores de las ruedas con posibilidad de deslizamiento axial sobre dicho eje y donde dichas ruedas no comparten el mismo par de giro.
ES2130039 de este mismo solicitante describe un conjunto de eje ferroviario dotado de cambio automático de ancho de vía y adaptable a bogies convencionales de mercancías. Dicho conjunto de eje ferroviario comprende dos conjuntos de rodadura independientes que carecen de un par de giro solidario. ES2151871 describes a self-propelled variable width rolling bogie, where the bogie has at least one fixed axle without rotation in which there are support boxes that allow the movement of the axle only vertically and sliding bushes carrying the wheels with possibility of axial sliding on said axle and where said wheels do not share the same torque. ES2130039 of this same applicant describes a rail axle assembly equipped with automatic track width change and adaptable to conventional merchandise bogies. Said railway axle assembly comprises two independent rolling assemblies that lack a solidarity torque.
ES2428239 describe un sistema ferroviario con cambio de ancho automático a múltiples anchos de vía. Las ruedas de este sistema ferroviario montadas sobre un eje incluyen varios rodamientos que permiten el giro independiente de cada una de las ruedas sin un par de giro solidario. Adicionalmente, dicho sistema ferroviario permite la transición entre anchos ferroviarios sin necesidad de liberar la carga de las ruedas. ES2428239 describes a railway system with automatic width change to multiple track widths. The wheels of this rail system mounted on an axle include several bearings that allow the independent rotation of each of the wheels without a torque of solidarity. Additionally, said railway system allows the transition between railway widths without the need to release the load of the wheels.
ES2204483 describe un bogie de rodadura de ancho variable autopropulsado con pares de ruedas con giro independiente sin par de giro solidario. Dichos pares de ruedas incluyen sistemas de rodamientos que reparten la carga radial con par de giro independiente para cada una de las ruedas. ES2204483 describes a self-propelled variable-width rolling bogie with pairs of wheels with independent rotation without integral turning torque. Said wheel pairs include bearing systems that distribute the radial load with independent torque for each of the wheels.
Así pues, una o más desventajas que ofrecen los bogies o conjuntos ferroviarios citados son una falta de sincronización entre pares de ruedas que puede causar un mal rendimiento debido a la carencia de un par de giro solidario entre ruedas del mismo par, un desgaste considerable por falta de robustez debido a las cargas axiales y/o radiales ejercidas sobre el conjunto ferroviario y un inmovilización deficiente de las ruedas durante el cambio de ancho para la adaptación a un ancho de vía específico. Thus, one or more disadvantages offered by the bogies or railway assemblies mentioned are a lack of synchronization between pairs of wheels that can cause a poor performance due to the lack of a pair of integral rotation between wheels of the same pair, considerable wear due to lack of robustness due to axial and / or radial loads exerted on the railway assembly and poor wheel immobilization during the change in width for adaptation to a specific track width.
Por este motivo se hace necesario un conjunto ferroviario más robusto que pueda circular en vías de distinto ancho, que ofrezca una mayor resistencia a las cargas axiales y/o radiales ejercidas sobre el conjunto ferroviario durante su funcionamiento, que ofrezca un sistema mejorado de inmovilización o sujeción de las ruedas durante el cambio de ancho en comparación con el estado de la técnica y que permita una sincronización de velocidad angular entres pares de ruedas del conjunto ferroviario. For this reason it is necessary a more robust railway assembly that can circulate on tracks of different width, which offers greater resistance to axial and / or radial loads exerted on the railway assembly during its operation, which offers an improved system of immobilization or clamping of the wheels during the change of width compared to the state of the art and that allows synchronization of angular speed between pairs of wheels of the railway assembly.

El rodamiento de empuje axial o lateral (10,19) desplaza axialmente los rodamientos de carga o soporte radial (11) sobre una pista de deslizamiento (13) fijada en el eje fijo (1) (o anillo interno de dicho rodamiento de carga o soporte radial (1 1)) permitiendo un conjunto de deslizamiento (12) que cambia y fija estancamente la posición de la rueda. The axial or lateral thrust bearing (10, 19) for the absorption of axial loads and radial load bearing or support (11) for the absorption of radial loads are arranged between the rotating axle of each of the wheels and the fixed axis (1). The axial or lateral thrust bearing (10,19) axially displaces the load bearing or radial support (11) on a sliding track (13) fixed on the fixed axis (1) (or internal ring of said load bearing or radial support (1 1)) allowing a sliding assembly (12) that changes and fixes the position of the wheel tightly.
La figura 5 muestra una vista en sección del segundo sistema ferroviario asociado al segundo conjunto ferroviario de la figura 2 en combinación con los primeros medios de tope de acuerdo con una realización de la presente invención. En la figura 5, el sistema de transmisión de par (16) permite el desplazamiento axial a uno de los ejes y es solidario al eje opuesto a la vez que está conectado a la rueda de dicho eje opuesto. También se pueden apreciar al igual que en la figura 4, los primeros medios de tope (6.7) que aseguran el bloqueo del par de ruedas (2). Similarmente al primer sistema de la figura 4, el rodamiento de empuje axial o lateral (10,19) para la absorción de las cargas axiales y los rodamientos de carga o soporte radial (1 1) para la absorción de las cargas radiales se disponen entre el eje giratorio de cada una de las ruedas y el eje fijo (1). El rodamiento de empuje axial o lateral (10,19) desplaza axialmente los rodamientos de carga o soporte radial (11) sobre una pista de deslizamiento (13) fijada en el eje fijo (1) (o anillo interno de dicho rodamiento de carga o soporte radial (11)) permitiendo un conjunto de deslizamiento (12) que cambia y fija estancamente la posición de la rueda. Figure 5 shows a sectional view of the second rail system associated with the second rail set of Figure 2 in combination with the first stop means according to an embodiment of the present invention. In Figure 5, the torque transmission system (16) allows axial displacement to one of the axles and is integral with the opposite axis while being connected to the wheel of said opposite axis. The first stop means (6.7) that ensure the locking of the pair of wheels (2) can also be seen as in Figure 4. Similar to the first system of Figure 4, the axial or lateral thrust bearing (10,19) for the absorption of axial loads and the radial load bearing or support (1 1) for the absorption of radial loads are arranged between the rotating axle of each of the wheels and the fixed axle (1). The axial or lateral thrust bearing (10,19) axially displaces the load bearing or radial support (11) on a sliding track (13) fixed on the fixed axis (1) (or internal ring of said load bearing or radial support (11)) allowing a sliding assembly (12) that changes and fixes the position of the wheel tightly.
La figura 6 muestra una vista en sección del tercer sistema ferroviario asociado al conjunto ferroviario de la figura 2 y en combinación con los segundos medios de tope, obteniendo así el tercer sistema ferroviario de acuerdo con una realización de la presente invención.
Los segundos medios de tope aseguran el bloqueo del par de ruedas (2), según la dirección lateral (3) comprenden un cubo (20) fijado en la parte exterior del eje fijo (1) y alojado en la caja de grasa (15). El cubo (20) funciona como tope entre los dos cerrojos (9) y una o más rótulas (21) o casquillos (22). El cubo (20) también funciona como sistema de empuje lateral hacia el rodamiento de empuje axial o lateral (10,19) a través de unos ejes tensores (23) que actúan como fijación entre el cubo (20) y el rodamiento de empuje axial o lateral (10, 19). Figure 6 shows a sectional view of the third rail system associated with the rail assembly of Figure 2 and in combination with the second stop means, thus obtaining the third rail system according to an embodiment of the present invention. The second stop means ensure the locking of the pair of wheels (2), according to the lateral direction (3) they comprise a hub (20) fixed on the outside of the fixed axle (1) and housed in the grease box (15) . The hub (20) functions as a stop between the two bolts (9) and one or more ball joints (21) or bushings (22). The hub (20) also functions as a lateral thrust system towards the axial or lateral thrust bearing (10,19) through tensioning shafts (23) that act as fixation between the hub (20) and the axial thrust bearing or lateral (10, 19).
Los ejes tensores (23) hacen de sistema anti giro para el rodamiento de empuje axial o lateral (10, 19), ya que, en este conjunto ferroviario, el eje fijo (1) no tiene ningún tipo de vaciado o mecanizado como se puede observar en la figura 6, es decir, este eje fijo (1) no comprende una espada (8) en contraste con los sistemas de las figuras 4 y 5 permitiendo que este sistema ferroviario sea todavía mucho más robusto y fiable que los sistemas previamente descritos. The tensioning shafts (23) act as an anti-rotation system for axial or lateral thrust bearing (10, 19), since, in this railway assembly, the fixed shaft (1) does not have any type of emptying or machining as can be done observe in figure 6, that is, this fixed axis (1) does not comprise a sword (8) in contrast to the systems of figures 4 and 5 allowing this rail system to be even more robust and reliable than the systems previously described .
Así pues, los ejes tensores (23) fijan el rodamiento de empuje axial o lateral (10, 19) consiguiendo así la correcta posición del par de ruedas (2) absorbiendo las cargas laterales que son provocadas con el empuje del par de ruedas en la dirección lateral (3) y aumentando la robusteza y disminuyendo el desgaste del sistema. Thus, the tensioning shafts (23) fix the axial or lateral thrust bearing (10, 19) thus achieving the correct position of the pair of wheels (2) absorbing the lateral loads that are caused by the thrust of the pair of wheels on the lateral direction (3) and increasing the robot and reducing system wear.
Similarmente a los primeros medios de tope (6,7), en los segundos medios de tope el rodamiento de empuje axial o lateral (10,19) para la absorción de las cargas axiales y los rodamientos de carga o soporte radial (11) para la absorción de las cargas radiales se disponen entre el eje giratorio de cada una de las ruedas y el eje fijo (1). El rodamiento de empuje axial o lateral (10,19) desplaza axialmente los rodamientos de carga o soporte radial (11) sobre una pista de deslizamiento (13) fijada en el eje fijo (1) (o anillo interno de dicho rodamiento de carga o soporte radial (11)) permitiendo un conjunto de deslizamiento (12) que cambia y fija estancamente la posición de la rueda. Similar to the first stop means (6.7), in the second stop means the axial or lateral thrust bearing (10,19) for the absorption of axial loads and radial load bearing or support bearings (11) for The absorption of the radial loads are arranged between the rotating axle of each of the wheels and the fixed axle (1). The axial or lateral thrust bearing (10,19) axially displaces the load bearing or radial support (11) on a sliding track (13) fixed on the fixed axis (1) (or internal ring of said load bearing or radial support (11)) allowing a sliding assembly (12) that changes and fixes the position of the wheel tightly.
En la tapa (17) de la caja de grasa 15, se ubican los pares de patines de apoyo (4) y los apoyos de los casquillos (22) o rótulas (21) que nos permite la correcta distribución de las cargas que sufre todo el sistema. Estos patines de apoyo (4) con el sistema de cambio de ancho sin descarga de ruedas (2), serían opcionales.
