Sector tecnico de la inventionTechnical sector of the invention
El vehteulo terrestre de la presente invencion es de los que permite su desplazamiento con una baja o incluso nula emision de gases contaminantes.The land vehicle of the present invention is one that allows its displacement with a low or even zero emission of polluting gases.
Antecedentes de la invencionBackground of the invention
Son conocidos vehiculos terrestres tales como coches, autobuses, camiones etc. provistos de ruedas con neumaticos de goma o caucho que permiten su frenada en una distancia corta. No obstante, este tipo de vehiculos son autonomos y precisan necesariamente un deposito de combustible o baterias para su desplazamiento, que ocupan una parte sustancial de su interior. Actualmente, la mayoria de vehiculos autonomos son vehiculos provistos de motores de combustion interna, cuyas emisiones son gases contaminantes y particulas que causan polucion.Land vehicles such as cars, buses, trucks etc. are known. provided with wheels with rubber or rubber tires that allow their braking over a short distance. However, these types of vehicles are autonomous and necessarily require a fuel tank or batteries for their displacement, which occupy a substantial part of their interior. Currently, most autonomous vehicles are vehicles equipped with internal combustion engines, whose emissions are polluting gases and particles that cause pollution.
Tambien se conocen vehiculos que estan desprovistos de deposito de combustible o baterias para asi conseguir una mayor capacidad, tales como los tranvias. Este tipo de vehiculos se alimentan mediante una catenaria superior a traves de un trole para accionar un motor electrico, consiguiendo asi no causar emisiones de gases contaminantes derivados de la combustion. No obstante, los tranvias estan provistos de ruedas metalicas y se desplazan, confinados, por carriles metalico, por lo que este tipo de vehiculos no solo estan obligados a realizar recorridos por carriles habilitados sino que ademas precisan una mayor distancia de frenado que los vehiculos provistos de neumaticos provocando accidentes graves. Ademas, este tipo de vehiculos tiene un coste muy elevado.Also known are vehicles that are devoid of fuel storage or batteries to achieve greater capacity, such as trams. These types of vehicles are fed by an overhead catenary through a trolley to drive an electric motor, thus not causing emissions of polluting gases derived from combustion. However, the trams are provided with metal wheels and are moved, confined, by metal rails, so that this type of vehicle is not only required to make journeys on authorized lanes but also requires a greater braking distance than the vehicles provided of tires causing serious accidents. In addition, this type of vehicle has a very high cost.
Es por tanto un objetivo de la presente invencion dar a conocer un vehiculo terrestre que cause menor o incluso nula emision de gases contaminantes, pueda utilizarse en cualquier lugar y tenga un coste mucho menor que los vehiculos conocidos.It is therefore an objective of the present invention to disclose a land vehicle that causes less or even zero emission of pollutant gases, can be used anywhere and has a much lower cost than known vehicles.
Explication de la invencionExplanation of the invention
El vehiculo terrestre de la presente invencion es de los que comprende un chasis montado sobre ruedas provistas de neumaticos, estando dichas ruedas conectadas a unos medios de direction para controlar la trayectoria del vehiculo y a unos medios de traccion para impulsar el vehiculo, estando los medios de traccion adaptados para ser accionados por un motorThe land vehicle of the present invention is one of those comprising a chassis mounted on wheels provided with tires, said wheels being connected to a directional means to control the trajectory of the vehicle and to a means of traction to drive the vehicle, the means being traction adapted to be driven by an engine

En esencia, el vehiculo se caracteriza porque, estando el motor electrico provisto de un polo positivo y de un polo negativo para su alimentacion electrica, el trole superior esta conectado al polo positivo del motor electrico, y porque el vehiculo esta provisto ademas de un trole inferior conectado al polo negativo del motor electrico, estando el trole inferior adaptado para conectar el polo negativo del motor electrico a un rail dispuesto en el suelo sobre el que circula el vehiculo que solo tiene la utilidad de evacuar la corriente, estando el motor electrico adaptado para accionar los medios de traccion cuando recibe corriente electrica entre el trole superior y el trole inferior, y estando ademas el vehiculo provisto de unos medios auxiliares adaptados para accionar los medios de traccion cuando el motor electrico no recibe corriente electrica entre el trole superior y el trole inferior. Ventajosamente, el vehiculo esta provisto ademas de unos medios auxiliares adaptados para accionar los medios de traccion cuando el motor electrico no recibe corriente electrica entre el trole superior y el trole inferior, de modo que se puedan utilizar los medios auxiliares para desplazar el vehiculo aun cuando este no se encuentre conectado entre la catenaria y el rail, es decir, que pueda utilizarse en cualquier lugar. Naturalmente, se preve que la catenaria este formada por uno o mas filamentos paralelos, asi como el rail puede estar formado tanto por una sola barra clavada al suelo o al asfalto como por multiples barras paralelas clavadas al suelo, para un transporte mas eficiente de la corriente electrica.In essence, the vehicle is characterized in that, since the electric motor is provided with a positive pole and a negative pole for its electrical supply, the upper trolley is connected to the positive pole of the electric motor, and because the vehicle is provided in addition to a trolley bottom connected to the negative pole of the electric motor, the lower trolley being adapted to connect the negative pole of the electric motor to a rail arranged on the ground on which the vehicle circulates that only has the utility of evacuating the current, the electric motor being adapted to drive the traction means when it receives electric current between the upper trolley and the lower trolley, and the vehicle also being provided with auxiliary means adapted to drive the traction means when the electric motor does not receive electric current between the upper trolley and the bottom trolley Advantageously, the vehicle is also provided with auxiliary means adapted to drive the traction means when the electric motor does not receive electric current between the upper trolley and the lower trolley, so that the auxiliary means can be used to move the vehicle even when This is not connected between the catenary and the rail, that is, it can be used anywhere. Naturally, it is anticipated that the catenary is formed by one or more parallel filaments, just as the rail can be formed by a single bar nailed to the ground or to the asphalt as well as multiple parallel bars nailed to the ground, for a more efficient transport of the electric current.
En una variante de realizacion, los medios auxiliares son un motor de combustion interna o de explosion, auxiliar, de los provistos de pistones, adaptado para utilizar un combustible tal como gasolina, gasoleo, gas u otros carburantes. Este motor de combustion interna o de explosion esta conectado a los medios de traccion a modo de medios auxiliares para accionar los medios de traccion y desplazar el vehiculo cuando este no se encuentre conectado entre la catenaria y el rail. Se preve que el conductor pueda arrancar el motor auxiliar cuando dirija el vehiculo fuera del recorrido provisto de catenaria y rail, permitiendo asi ventajosamente utilizar el motor electrico cuando se encuentra en un recorrido provisto de catenaria y rail y utilizar el motor auxiliar de combustibles cuando se encuentra fuera del recorrido provisto de catenaria y rail.In a variant embodiment, the auxiliary means are an internal combustion or explosion combustion engine, provided with pistons, adapted to use a fuel such as gasoline, diesel, gas or other fuels. This internal combustion or explosion engine is connected to the traction means by way of auxiliary means to drive the traction means and move the vehicle when it is not connected between the catenary and the rail. It is envisaged that the driver can start the auxiliary engine when driving the vehicle out of the path provided with catenary and rail, thus allowing advantageously to use the electric motor when it is in a path provided with catenary and rail and use the auxiliary fuel engine when It is outside the route provided with catenary and rail.
En otra variante de realization, los medios auxiliares pueden ser baterias electricas conectadas al motor electrico, que pueden ser ventajosamente utilizadas para alimentar el motor electrico y asi accionar los medios de traccion y desplazar el vehiculo cuando elIn another variant of realization, the auxiliary means can be electric batteries connected to the electric motor, which can be advantageously used to power the electric motor and thus drive the traction means and move the vehicle when the

vehteulo se encuentra fuera del recorrido provisto de catenaria y rail, o no fluye corriente entre ellos. De esta manera, ventajosamente el conductor puede establecer que el motor electrico se alimente de las baterias cuando no se alimenta de la corriente entre el trole superior y el trole inferior.vehicle is out of the path provided with catenary and rail, or no current flows between them. In this way, the driver can advantageously establish that the electric motor is fed from the batteries when it is not fed from the current between the upper trolley and the lower trolley.
Naturalmente, se preve tambien que el vehiculo este provisto a la vez de unos medios auxiliares en forma de motor de combustion interna o de explosion y de unos medios auxiliares en forma de baterias conectadas al motor electrico, permitiendo que el conductor elija los medios auxiliares a accionar cuando el motor electrico no se alimenta a traves del trole superior y del trole inferior, por ejemplo mediante diferentes interruptores de mando.Naturally, it is also provided that the vehicle is provided with both auxiliary means in the form of an internal combustion or explosion engine and auxiliary means in the form of batteries connected to the electric motor, allowing the driver to choose the auxiliary means to actuate when the electric motor is not fed through the upper trolley and the lower trolley, for example by means of different control switches.
Se da a conocer tambien que, aunque el vehiculo electrico pueda estar provisto de un solo motor electrico, tambien se preve que comprenda una pluralidad de motores electricos conectados al trole superior y al trole inferior, por ejemplo, uno en cada par de ruedas motrices.It is also known that, although the electric vehicle may be provided with a single electric motor, it is also provided that it comprises a plurality of electric motors connected to the upper trolley and the lower trolley, for example, one in each pair of driving wheels.
Segun otra caracteristica de la invencion, el extremo del trole superior esta provisto de un terminal superior horizontal transversal que facilita el contacto con la catenaria dispuesta a lo largo del circuito para el recorrido del vehiculo en una direccion longitudinal, por lo que el terminal superior sera transversal tanto a la catenaria como a la direccion del vehiculo.According to another characteristic of the invention, the end of the upper trolley is provided with a transverse horizontal upper terminal that facilitates contact with the catenary arranged along the circuit for the vehicle travel in a longitudinal direction, whereby the upper terminal will be transversal to both the catenary and the direction of the vehicle.
Segun otra caracteristica de la invencion, el extremo del trole inferior esta provisto de un terminal inferior horizontal transversal que facilita el contacto con el carril dispuesto a lo largo del circuito para el recorrido del vehiculo en una direccion longitudinal, por lo que el terminal inferior sera transversal tanto al carril como a la direccion del vehiculo. Se preve por tanto que el terminal superior y el terminal inferior, ambos preferentemente horizontales, sean paralelos. El hecho de que el terminal superior y el terminal inferior sea horizontales permite ventajosamente que el vehiculo pueda desplazarse lateralmente hasta cierto punto manteniendo el contacto con la catenaria y el rail.According to another characteristic of the invention, the end of the lower trolley is provided with a transverse horizontal lower terminal that facilitates contact with the rail arranged along the circuit for the vehicle travel in a longitudinal direction, whereby the lower terminal will be transversal to both the lane and the direction of the vehicle. It is therefore envisaged that the upper terminal and the lower terminal, both preferably horizontal, are parallel. The fact that the upper terminal and the lower terminal are horizontal advantageously allows the vehicle to move laterally to a certain extent while maintaining contact with the catenary and the rail.
Segun otra caracteristica de la invencion, el terminal inferior del trole inferior esta provisto de ruedas auxiliares en sus extremos que permiten posicionar el terminal inferior del trole inferior a una altura minima y suficiente para que contacte con el carril sin rozar el suelo.According to another characteristic of the invention, the lower terminal of the lower trolley is provided with auxiliary wheels at its ends that allow the lower terminal of the lower trolley to be positioned at a minimum and sufficient height to contact the rail without touching the ground.
Segun otro aspecto de la invencion, las ruedas son de goma mejorando el agarre del vehiculo al suelo, lo que mejora substancialmente su distancia de frenada.According to another aspect of the invention, the wheels are made of rubber improving the grip of the vehicle on the ground, which substantially improves its braking distance.

Segun otra caracteristica de la invention, el vehteulo comprende unos medios de aviso, tal como un piloto luminoso o un aviso acustico, conectados entre el trole superior y el trole inferior para avisar al conductor cuando no circula corriente electrica entre el trole superior y el trole inferior, por lo que el motor electrico no esta siendo alimentado por el conjunto de catenaria y carril. En este caso, el conductor deberia accionar el medio auxiliar para continuar accionando los medios de traction y asi proseguir la marcha del vehiculo. Se preve que otra variante de realization el accionamiento de los medios auxiliares pueda realizarse mediante componentes electronicos de control, de modo que no sea preciso el conductor accione manualmente los medios auxiliares.According to another characteristic of the invention, the vehicle comprises warning means, such as a pilot light or an acoustic warning, connected between the upper trolley and the lower trolley to notify the driver when no electric current circulates between the upper trolley and the trolley lower, so the electric motor is not being powered by the catenary and rail assembly. In this case, the driver should operate the auxiliary means to continue driving the traction means and thus continue the vehicle's progress. It is envisaged that another variant of realization can be performed by means of electronic control components, so that the driver does not manually activate the auxiliary means.

Las Figs.1 y 2 presentan de manera esquematica un vehiculo 1 terrestre de la presente invencion que puede ser tanto un autobus, un coche, un camion o cualquier otro tipo de vehiculo que permita el desplazamiento por tierra sobre ruedas y que comprende un chasis 2 montado sobre unas ruedas 3 provistas de neumaticos de goma o caucho que permiten el desplazamiento del vehiculo y permiten su frenado en un corta distancia corta, puesto que las ruedas 3 provistas de neumaticos ofrecen un buen agarre al suelo 20 sobre el que se desplaza el vehiculo 1. Como se vera mas adelante, las ruedas 3 estan conectadas a unos medios de direction 4 que permiten controlar la trayectoria del vehiculo, favoreciendo el giro de las ruedas a traves de un volante de modo conocido. Tambien las ruedas 3 estan conectadas aFigs. 1 and 2 schematically present a land vehicle 1 of the present invention that can be both a bus, a car, a truck or any other type of vehicle that allows the movement on land on wheels and that comprises a chassis 2 mounted on wheels 3 provided with rubber or rubber tires that allow the vehicle to move and allow its braking in a short distance, since the wheels 3 provided with tires offer a good grip on the ground 20 on which the vehicle moves 1. As will be seen later, the wheels 3 are connected to means of direction 4 that allow controlling the trajectory of the vehicle, favoring the rotation of the wheels through a steering wheel in a known manner. Also the wheels 3 are connected to

unos medios de traccion 5 que permiten hacer girar las ruedas 3 para impulsar el vehteulo. Naturalmente, se preve que algunas ruedas 3 sean ruedas motrices y esten conectadas a los medios de traccion 5, mientras que otras ruedas 3 sean ruedas directrices y esten conectadas a los medios de direccion 4, de manera similar a las ruedas 3 de los vehiculos 1 terrestres conocidos, tales como coches, camiones o autobuses.traction means 5 that allow the wheels 3 to be turned to drive the vehicle. Naturally, it is anticipated that some wheels 3 are driving wheels and are connected to the traction means 5, while other wheels 3 are steering wheels and are connected to the steering means 4, similar to the wheels 3 of the vehicles 1 known land, such as cars, trucks or buses.
El vehiculo 1 puede bien desplazarse en un circuito provisto de un conjunto de catenaria 10 y rail 12, alimentandose de la corriente electrica entre la catenaria 10 y rail 12 o bien fuera del circuito, por lo que los medios de traccion 5 se accionaran mediante unos medios auxiliares 13 adaptados para accionar los medios de traccion 5 cuando el vehiculo 1 no puede alimentarse de la corriente electrica entre la catenaria 10 y el rail 12, como se detallara mas adelante.The vehicle 1 can either move in a circuit provided with a set of catenary 10 and rail 12, feeding on the electric current between the catenary 10 and rail 12 or outside the circuit, whereby the traction means 5 will be operated by means of auxiliary means 13 adapted to drive the traction means 5 when the vehicle 1 cannot feed on the electric current between the catenary 10 and the rail 12, as will be detailed below.
Como se puede observar en las Figs. 1 y 2, el vehiculo 1 esta provisto de un trole superior 9 y de un trole inferior 11 que sobresalen del chasis 2 del vehiculo 1. Asi, el trole superior 9 esta adaptado para conectarse a una catenaria 10 que transcurre por encima del vehiculo 1 en un carril adaptado y el trole inferior 11 esta adaptado para conectarse a un rail 12 dispuesto en el suelo 20 de dicho carril adaptado sobre el que circula el vehiculo 1.As can be seen in Figs. 1 and 2, the vehicle 1 is provided with an upper trolley 9 and a lower trolley 11 protruding from the chassis 2 of the vehicle 1. Thus, the upper trolley 9 is adapted to be connected to a catenary 10 that runs over the vehicle 1 in an adapted rail and the lower trolley 11 is adapted to be connected to a rail 12 disposed on the floor 20 of said adapted rail on which the vehicle 1 circulates.
El carril en el que se preve que pueda circular dicho vehiculo 1 esta provisto de una catenaria 10, que como se puede ver en las Figs. 1 y 2 puede estar formado por un filamento, y de un rail 12 que puede estar formado por una barra. Entre la catenaria 10 y el rail 12 se preve que exista una diferencia de voltaje para que tras conectarse circule una corriente electrica de la catenaria 10 al rail 12. Esta diferencia de voltaje puede establecerse mediante un generador 21 del modo ilustrado. Naturalmente, se preve que el generador 21 pueda ser de diferente naturaleza e incluso que forme parte de una red electrica que sirva para alimentar el conjunto de catenaria 10 y rail 12.The lane in which said vehicle 1 can be circulated is provided with a catenary 10, which as can be seen in Figs. 1 and 2 can be formed by a filament, and a rail 12 that can be formed by a bar. Between the catenary 10 and the rail 12 it is expected that there is a voltage difference so that after connecting an electric current from the catenary 10 to the rail 12 is circulated. This voltage difference can be established by a generator 21 in the manner illustrated. Naturally, it is envisioned that the generator 21 may be of a different nature and even that it is part of an electrical network that serves to power the catenary assembly 10 and rail 12.
Como se puede observar en las Figs. 1 y 2, el extremo del trole superior 9 esta provisto de un terminal superior 17 horizontal que permite contactar con la catenaria 10 y el extremo del trole inferior 11 esta provisto de un terminal inferior 18 horizontal que permite contactar con el rail 12, de modo que aunque el vehiculo no este exactamente centrado en el carril se consiga un buen contacto electrico y permita que el conductor pueda realizar pequenos desplazamientos laterales, por ejemplo para sortear un obstaculo, sin que se pierda el contacto con la catenaria 10 y el rail 12.As can be seen in Figs. 1 and 2, the end of the upper trolley 9 is provided with a horizontal upper terminal 17 allowing contact with the catenary 10 and the end of the lower trolley 11 is provided with a horizontal lower terminal 18 allowing contact with the rail 12, so that although the vehicle is not exactly centered on the rail, a good electrical contact is achieved and allows the driver to make small lateral displacements, for example to overcome an obstacle, without losing contact with the catenary 10 and the rail 12.

Para un mejor contacto del terminal inferior 18 del trole inferior 11 con el rail 12, se puede observar que el terminal inferior 18 esta provisto de unas ruedas auxiliares 19 en sus extremos que permiten que el terminal inferior 18 del trole inferior 11 quede debidamente dispuesto sobre el rail 10 sin que roce el suelo 20. Se preve tambien que el terminal inferior 18 del trole inferior 11 este provisto de un sensor, tal como un sensor por contacto que determine la altura a la que debe situarse el terminal inferior 18 del trole inferior 11 para contactar correctamente con el rail 12. Naturalmente, se preve que tanto el trole superior 9 como el trole inferior 11 sean retractiles o puedan subirse y bajarse a voluntad, de modo que el conductor del vehiculoFor a better contact of the lower terminal 18 of the lower trolley 11 with the rail 12, it can be seen that the lower terminal 18 is provided with auxiliary wheels 19 at its ends that allow the lower terminal 18 of the lower trolley 11 to be properly disposed on the rail 10 without rubbing the floor 20. It is also provided that the lower terminal 18 of the lower trolley 11 is provided with a sensor, such as a contact sensor that determines the height at which the lower terminal 18 of the lower trolley should be placed. 11 to correctly contact rail 12. Naturally, it is anticipated that both the upper trolley 9 and the lower trolley 11 are retractable or can be raised and lowered at will, so that the driver of the vehicle
I pueda accionarlos a voluntad para que contacten, segun sea, con la catenaria 10 y el rail 12. Se preve tambien que el vehiculo 1 este provisto de unos medios de aviso, tales como un piloto luminosos o un avisado acustico, conectados entre el trole superior 9 y el trole inferior 11, de modo que el conductor pueda estar informado de si el trole superior 9 y el trole inferiorI can drive them at will to contact, as the case may be, with catenary 10 and rail 12. It is also envisaged that vehicle 1 is provided with warning means, such as a light pilot or acoustic warning, connected between the trolley upper 9 and lower trolley 11, so that the driver can be informed of whether the upper trolley 9 and the lower trolley
II hacen buen contacto y a traves de ellos fluye corriente electrica para alimentar el motor electrico 6.II make good contact and through them electric current flows to power the electric motor 6.
Como se ilustra en la Fig. 3, los medios de traccion 5 del vehiculo 1 estan adaptados para ser accionados por un motor electrico 6, de modo que al alimentarse el motor electrico 6 se accionan los medios de traccion 5 que hacen girar las ruedas 3. Naturalmente, se preve que los medios de traccion 5 del vehiculo puedan regularse por parte de un conductor del vehiculo 1, por ejemplo, mediante un pedal de acelerador que permitan girar mas o menos rapidamente las ruedas, de modo conocido. Como se puede observar, el motor electrico 6 esta provisto de un polo positivo 7 y de un polo negativo 8 para su alimentacion electrica, estando el polo positivo 7 adaptado para conectarse a un terminal electrico positivo, es decir a la parte positiva de una diferencia de potencial y el polo negativo 8 adaptado para conectarse a un terminal electrico negativo, es decir a la parte negativa de una diferencia de potencial. Naturalmente, se preve que las denominaciones polo positivo 7 y polo negativo 8 sean intercambiables en funcion de la naturaleza del motor electrico 6 o incluso no exista distincion entre los polos.As illustrated in Fig. 3, the traction means 5 of the vehicle 1 are adapted to be driven by an electric motor 6, so that when the electric motor 6 is powered, the traction means 5 that rotates the wheels 3 is driven Naturally, it is envisioned that the driving means 5 of the vehicle can be regulated by a driver of the vehicle 1, for example, by means of an accelerator pedal that allows the wheels to rotate more or less rapidly, in a known manner. As can be seen, the electric motor 6 is provided with a positive pole 7 and a negative pole 8 for its power supply, the positive pole 7 being adapted to be connected to a positive electrical terminal, that is to the positive part of a difference of potential and the negative pole 8 adapted to connect to a negative electrical terminal, that is to the negative part of a potential difference. Naturally, the designations positive pole 7 and negative pole 8 are expected to be interchangeable depending on the nature of the electric motor 6 or there is no distinction between the poles.
Como se puede ver en la Fig. 3, el trole superior 9 esta conectado al polo positivo 7 del motor electrico 6, y el trole inferior 11 esta conectado al polo negativo 8 del motor electrico 6, estando el motor electrico 6 adaptado para accionar los medios de traccion 5 cuando recibe corriente electrica entre el trole superior 9 y el trole inferior 11. Se preve que puedan instalarse uno o mas motores electricos 6 en el vehiculo segun sea necesario, por ejemplo, es posible que cada par de ruedas motrices este asociado a un motor electrico 6.As can be seen in Fig. 3, the upper trolley 9 is connected to the positive pole 7 of the electric motor 6, and the lower trolley 11 is connected to the negative pole 8 of the electric motor 6, the electric motor 6 being adapted to drive the traction means 5 when receiving electric current between the upper trolley 9 and the lower trolley 11. It is envisioned that one or more electric motors 6 can be installed in the vehicle as necessary, for example, it is possible that each pair of driving wheels is associated to an electric motor 6.

De esta manera, cuando el motor electrico 6 no recibe corriente electrica entre el trole superior 9 y el trole inferior 11, el conductor puede arrancar el motor de combustion interna 14 que forma los medios auxiliares 13 para mantener el accionamiento de los medios de traccion 5 y asi poder continuar moviendo el vehiculo 1 cuando este no se encuentra en un carril provisto de catenaria 10 y rail 12. Naturalmente, los medios de traccion 5 estaran debidamente provistos de mecanismos conocidos para permitir su accionamiento tanto por el motor electrico 6 como por el motor de combustion interna 14 de los medios auxiliares 13. Como se ha indicado anteriormente, las ruedas 3 tambien estaran conectadas a unos medios de direction 4, de modo conocido, para controlar la trayectoria del vehiculo 1.to drive the traction means 5 when the electric motor 6 does not receive electric current between the upper trolley 9 and the lower trolley 11. These auxiliary means 13 in the variant shown in Fig. 3 are an internal combustion engine, for example, a piston engine that is fed by gasoline or diesel. Thus, when the electric motor 6 does not receive electric current between the upper trolley 9 and the lower trolley 11, the driver can start the internal combustion engine 14 that forms the auxiliary means 13 to maintain the drive of the traction means 5 and thus being able to continue moving the vehicle 1 when it is not in a lane provided with catenary 10 and rail 12. Naturally, the traction means 5 will be duly provided with known mechanisms to allow its operation both by the electric motor 6 and by the internal combustion engine 14 of the auxiliary means 13. As indicated above, the wheels 3 will also be connected to means of direction 4, in a known manner, to control the trajectory of the vehicle 1.
La Fig. 4 presenta otra variante de realization del vehiculo en la que los medios auxiliares 13 adaptados para accionar los medios de traccion 5 cuando el motor electrico 6 no recibe corriente electrica entre el trole superior 9 y el trole inferior 11 son una o mas baterias electricas 15. En este caso, a diferencia de la variante de realizacion anteriormente descrita en la Fig. 3 no sera necesario que los medios de traccion 5 esten preparados para recibir accionamiento de dos motores diferentes, sino que solamente sera necesario que esten preparados para recibir accionamiento del motor electrico 6, pues como se puede observar en la Fig. 4, en este caso los medios auxiliares 13 seran una o mas baterias electricas 15 y el motor electrico 6 estara preparado para alimentarse de dichas una o mas baterias electricas 15 cuando no reciba corriente electrica entre el trole superior 9 y el trole inferior 11. Naturalmente, se preve que las baterias electricas 15 puedan recargarse, por ejemplo a partir de la energia recuperada por la frenada del vehiculo 1, de modo conocido.Fig. 4 shows another variant embodiment of the vehicle in which the auxiliary means 13 adapted to drive the traction means 5 when the electric motor 6 does not receive electric current between the upper trolley 9 and the lower trolley 11 are one or more batteries electric 15. In this case, unlike the variant of embodiment described above in Fig. 3 it will not be necessary for the traction means 5 to be prepared to receive drive from two different motors, but it will only be necessary for them to be prepared to receive electric motor drive 6, as can be seen in Fig. 4, in this case the auxiliary means 13 will be one or more electric batteries 15 and the electric motor 6 will be prepared to be powered by said one or more electric batteries 15 when not receive electric current between the upper trolley 9 and the lower trolley 11. Naturally, it is envisioned that the electric batteries 15 can be recharged, for example ap from the energy recovered by the braking of vehicle 1, in a known manner.
Tambien se preve que los medios auxiliares 13 sean un conjunto de motor de combustion interna 14 y baterias electricas 15, combinando los esquemas de las Figs. 3 y 4 y permitiendo por ejemplo al conductor decidir si activar el motor de combustion interna 14 o las baterias electricas 15 segun crea mas conveniente cuando el motor electrico 6 no recibe corriente electrica entre el trole superior 9 y el trole inferior 11.It is also envisioned that the auxiliary means 13 are an internal combustion engine assembly 14 and electric batteries 15, combining the schemes of Figs. 3 and 4 and allowing, for example, the driver to decide whether to activate the internal combustion engine 14 or the electric batteries 15 as it deems most convenient when the electric motor 6 does not receive electric current between the upper trolley 9 and the lower trolley 11.
