Description

Propulsión de una rueda individual para vehículos de tracción eléctrica, en particular tranvías.Propulsion of an individual wheel for electric traction vehicles, particularly trams.

Campo técnicoTechnical field

La invención se refiere a la propulsión de una rueda de vehículo ferroviario con montaje pivotante sobre un eje trasero.The invention relates to the propulsion of a railway vehicle wheel with pivot mounting on an axle rear.

Técnica anteriorPrior art

Existen particularmente dos diseños aplicados para diseñar la propulsión de vehículos conocidos hasta ahora.There are particularly two applied designs to design the propulsion of known vehicles so far.

El primer grupo de soluciones se caracteriza por un motor construido directamente en la estructura de la rueda. El motor se convierte de este modo en una parte de la masa no suspendida del vehículo y por lo tanto tiene una influencia negativa sobre las fuerzas dinámicas entre el vehículo y los raíles. El propio motor está expuesto a grandes fuerzas dinámicas. Las Patentes DE 42 34 831 C1 y EP 0 464 929 A3 sirven como ejemplo de esta solución.The first group of solutions is characterized by an engine built directly on the structure of the wheel. He motor thus becomes a part of the mass not suspended from the vehicle and therefore has an influence negative on the dynamic forces between the vehicle and the rails. The engine itself is exposed to great dynamic forces. The Patents DE 42 34 831 C1 and EP 0 464 929 A3 serve as an example of This solution.

El Segundo grupo de soluciones se caracteriza por un motor montado de forma independiente de la rueda y suspendido frente a la rueda. La transmisión de momento entre el motor y la rueda se resuelve mediante uniones o mecanismos expuestos al desgaste y envejecimiento. Las invenciones EP 0 760 305 A2, DE 196 00420 C1 y DE 195 31 355 A1 pueden servir como ejemplo del segundo grupo de soluciones.The second group of solutions is characterized by an engine mounted independently of the wheel and suspended  in front of the wheel. The moment transmission between the engine and the wheel is resolved by joints or mechanisms exposed to wear and aging Inventions EP 0 760 305 A2, DE 196 00420 C1 and DE 195 31 355 A1 can serve as an example of the second solution group.

Las desventajas de las soluciones anteriores son, por lo tanto, una gran proporción de masas no suspendidas de un vehículo y los subsiguientes efectos dinámicos o el uso de partes costosas que requieren un mantenimiento y sustitución periódicos.The disadvantages of the previous solutions they are, therefore, a large proportion of non-suspended masses of a vehicle and subsequent dynamic effects or the use of parts costly that require maintenance and replacement newspapers

Naturaleza de la invenciónNature of the invention

Las desventajas de las soluciones conocidas se eliminan mediante una propulsión de una rueda individual, particularmente aplicable a una rueda de tranvía, montada sobre un eje trasero, cuya naturaleza se basa en el principio de que el motor de arrastre está montado de forma basculante en un mecanismo de suspensión conectado firmemente a las partes suspendidas de un vehículo, y la rueda motriz de un vehículo ferroviario está montada sobre un perno del eje trasero de tal manera que existe una cavidad en el interior del perno para la ubicación del árbol motor del motor de arrastre, o para la ubicación del árbol motor del motor de arrastre y de una unión articulada.The disadvantages of known solutions are removed by a single wheel drive, particularly applicable to a tram wheel, mounted on a rear axle, whose nature is based on the principle that the drive motor is pivotally mounted on a mechanism of suspension firmly connected to the suspended parts of a vehicle, and the driving wheel of a railway vehicle is mounted on a rear axle bolt such that there is a cavity inside the bolt for the location of the motor shaft of the drive motor, or for the location of the motor motor shaft of drag and an articulated joint.

El árbol motor del motor de arrastre está conectado, por medio de una unión articulada con flexibilidad angular y axial, a la rueda motriz del vehículo ferroviario montada de forma pivotante sobre un perno del eje trasero.The drive motor drive shaft is connected, by means of an articulated joint with flexibility angular and axial, to the driving wheel of the mounted rail vehicle pivotally on a rear axle bolt.

Un motor suspendido de esta manera, en combinación con una caja de cambios, o un motor con una caja de cambios y un freno de fricción o un motor con un freno de fricción puede formar una unidad motriz.A motor suspended in this way, in combination with a gearbox, or an engine with a gearbox changes and a friction brake or an engine with a friction brake It can form a motor unit.

La disposición de acuerdo con la invención con un motor de arrastre suspendido o una unidad motriz suspendida influirá favorablemente en la proporción entre masas suspendidas y no suspendidas de un vehículo, lo que dará como resultado menores efectos dinámicos entre el vehículo y el rail. La tensión de impacto sobre el motor también es menor que si éste estuviera construido en una rueda, lo que aumenta la fiabilidad y el ciclo de vida del motor.The arrangement according to the invention with a suspended drive motor or a suspended drive unit will favorably influence the proportion between suspended masses and not suspended from a vehicle, which will result in minor dynamic effects between the vehicle and the rail. Impact stress on the engine is also smaller than if it was built in a wheel, which increases the reliability and life cycle of the engine.

Explicación de las figuras en el dibujoExplanation of the figures in the drawing

La propulsión de una rueda individual de acuerdo con la invención se detalla en el dibujo adjunto, donde la Fig. 1 muestra una vista y una sección transversal de una versión con una unión de tipo rótula, y la Fig. 2 muestra una versión con una unión articulada con elementos flexibles.The propulsion of an individual wheel according with the invention it is detailed in the attached drawing, where Fig. 1 shows a view and a cross section of a version with a ball joint type, and Fig. 2 shows a version with a joint articulated with flexible elements.

Versión ejemplar de la invenciónExemplary version of the invention

La propulsión de una rueda individual, particularmente aplicable a ruedas de tranvía mostrada en la Fig. 1, consta de un motor de arrastre (1) suspendido de forma basculante mediante un mecanismo de suspensión (2) sobre un soporte (3), que está conectado a las partes suspendidas de un vehículo ferroviario, por ejemplo con el armazón del chasis. Un árbol motor (4) del motor de arrastre (1) está conectado por medio de una unión articulada angular y axialmente flexible (5) a un impulsor (6) montado sobre la rueda motriz del vehículo ferroviario (7) montada de forma pivotante sobre un perno (9) del eje trasero (8).The propulsion of an individual wheel, particularly applicable to tram wheels shown in Fig. 1,  consists of a trailed motor (1) suspended in a tilting way by means of a suspension mechanism (2) on a support (3), which is connected to the suspended parts of a rail vehicle, for example with the chassis frame. A motor shaft (4) of the engine drag (1) is connected by means of an articulated joint angular and axially flexible (5) to an impeller (6) mounted on the drive wheel of the rail vehicle (7) mounted in a way pivoting on a bolt (9) of the rear axle (8).

Durante el movimiento del vehículo, el motor de arrastre (1) está permanentemente conectado, mediante el árbol motor (4) y la unión articulada angular y axialmente flexible (5), a la rueda motriz del vehículo ferroviario (7), de modo que pueda aplicar un efecto de arrastre o de frenado sobre la rueda motriz del vehículo ferroviario (7). El momento de reacción del efecto de arrastre o de frenado se transfiere a las partes suspendidas del vehículo a través del mecanismo de suspensión basculante (2).During the movement of the vehicle, the engine of drag (1) is permanently connected, using the tree motor (4) and the angular and axially flexible articulated joint (5), to the driving wheel of the railway vehicle (7), so that it can apply a drag or brake effect on the driving wheel of the railway vehicle (7). The reaction moment of the effect of dragging or braking is transferred to the suspended parts of the vehicle through the tilting suspension mechanism (2).

Al desplazarse sobre desigualdades, se produce el movimiento vertical mutuo de la rueda motriz del vehículo ferroviario (7) y el motor de arrastre (1). El motor de arrastre (1) bascula en el mecanismo de suspensión basculante (2). Los impactos resultantes de este movimiento solamente se transfieren marginalmente al motor de arrastre y por lo tanto no son una amenaza para su funcionamiento.When moving over inequalities, it occurs mutual vertical movement of the vehicle's drive wheel railway (7) and the drive motor (1). The drive motor (1) swings on the rocker suspension mechanism (2). Impacts resulting from this movement are only transferred marginally to the drag engine and therefore are not a threat to its operation.

La Fig. 2 muestra una propulsión de rueda con montaje basculante del motor (1) con aplicación de una unión articulada (5) con elementos flexibles.Fig. 2 shows a wheel drive with tilting motor assembly (1) with application of a joint articulated (5) with flexible elements.
