Mejoras en trenes de dos vías y monorailes indescarrilables de muy alta velocidadTwo-way train upgrades and very high-speed non-derailing monorails
Campo de la invenciónField of the invention
En vehículos de transporte terrestre, parques de atracciones, juguetería, y en especial en trenes de alta velocidad.In land transport vehicles, amusement parks, toys, and especially high-speed trains.
Estado de la técnicaState of the art
Los sistemas de levitación experimentales actuales, como el maglev, utilizan vías excesivamente caras, su funcionamiento es muy complejo y necesitan una enorme cantidad de energía para su desplazamiento, lo cual los hace impracticables, quedando confinados al campo experimental. Los trenes convencionales son excesivamente pesados, produciendo gran fricción y alto gasto de energía. Los aviones no tienen rozamiento por rodadura, pero el gasto energético es elevado. Todos ellos presentan una gran resistencia frontal, trasera y de fricción a alta velocidad. La presente invención soluciona dichos problemas, utilizando trenes ultraligeros, y sencillas y económicas vías.Current experimental levitation systems, such as the maglev, use excessively expensive routes, their operation is very complex and they require an enormous amount of energy for their movement, which makes them impractical, being confined to the experimental field. Conventional trains are excessively heavy, producing great friction and high energy expenditure. Airplanes do not have rolling friction, but the energy consumption is high. All of them have great front, rear and friction resistance at high speed. The present invention solves these problems, using ultralight trains, and simple and inexpensive tracks.

Problema técnico actualCurrent technical problem
Los trenes actuales necesitan costosas vías, gran peso para adaptarse o adherirse a las mismas y evitar el descarrilamiento, no adquieren muy altas velocidades, son muy afectados por el viento lateral, la energía eléctrica externa se aplica con dificultad, la existencia frontal, posterior y lateral son muy elevadas, tienen gran gasto de energía, y por lo tanto son poco ecológicos. Se puede decir que no están al día respecto a otros avances tecnológicos. La presente invención soluciona dichos problemas.Current trains need expensive tracks, great weight to adapt or adhere to them and avoid derailment, they do not acquire very high speeds, they are very affected by the side wind, external electrical energy is applied with difficulty, the existence of the front, rear and lateral are very high, have great energy expenditure, and therefore are not very environmentally friendly. It can be said that they are not up to date with other technological advances. The present invention solves these problems.
Las mejoras en trenes de dos vías y monorraíles indescarrilables de muy alta velocidad, consiste en utilizar en los vagones de los trenes ultraligeros unas ruedas o ruedas poleas verticales o inclinados sobre unos raíles igualmente verticales o inclinados, con los cuales quedan atrapados, añadiendo unas ruedas de imanes permanentes o con electroimanes que se adosan, o discurren próximas y, atraídas por los raíles, pero permitiendo su giro libremente, añadiendo unos sistemas reductores de la fricción lateral.The improvements in two-track trains and very high-speed non-derailing monorails consist of using vertical or inclined wheels or pulleys in the wagons of ultralight trains on equally vertical or inclined rails, with which they are trapped, adding wheels of permanent magnets or with electromagnets that are attached, or run close to each other and, attracted by the rails, but allowing them to rotate freely, adding lateral friction reducing systems.
Las ruedas pueden ser independientes o usarse por parejas con un eje común. Las de eje común pueden tener el eje aislado en su zona media, para permitir la alimentación eléctrica por los raíles y las ruedas como con las ruedas independientes que pueden estar aisladas.The wheels can be independent or used in pairs with a common axle. Those with a common axle can have the axle isolated in its middle zone, to allow the electrical supply through the rails and the wheels as with the independent wheels that can be isolated.
La cabeza de los raíles puede ser de sección circular, semicircular o semiovalada, rectangular con sus esquinas redondeadas y también raíles estándar. Pueden utilizarse los raíles perpendiculares y las ruedas poleas inclinadas a ambos lados. Las ruedas pueden ser libres o motoras, en el primer caso los trenes serían propulsados solo por los fanes.The head of the rails can be of circular, semi-circular or semi-oval section, rectangular with rounded corners and also standard rails. Perpendicular rails and pulley wheels inclined on both sides can be used. The wheels can be free or motorized, in the first case the trains would be propelled only by the fans.
La resistencia frontal y trasera se reduce usando fanes o turbinas, las cuales succionan el aire en la zona frontal del vagón delantero y otras lo descargan en la posterior del último vagón. La fricción lateral se reduce utilizando múltiples microranuras por las que se insufla aire, produciendo microburbujas, se pueden disponer verticales u horizontales.The front and rear resistance is reduced by using fans or turbines, which suck the air in the front area of the front car and others discharge it in the rear of the last car. The Lateral friction is reduced by using multiple microgrooves through which air is blown, producing microbubbles, they can be arranged vertically or horizontally.
Los motores eléctricos se pueden aplicar directamente a las ruedas y se alimentan con baterías, células de combustible o con la corriente eléctrica aplicada desde tierra aplicada a las vías y captada por las ruedas, o por unas grandes placas fijas que actúan de condensadores con otras placas en la zona inferior o lateral de los vagones. Los raíles pueden hacer de masa o bien se puede utilizar una segunda placa para la misma. La corriente alterna aplicada tiene una frecuencia y voltaje relativamente altos para permitir su circulación a través de los condensadores.Electric motors can be applied directly to the wheels and are powered by batteries, fuel cells or with the electrical current applied from the ground applied to the tracks and captured by the wheels, or by large fixed plates that act as capacitors with other plates in the lower or lateral zone of the wagons. The rails can be used as dough or a second plate can be used for it. The applied alternating current has a relatively high frequency and voltage to allow it to flow through the capacitors.
En todos los casos las ruedas rodean y atrapan los raíles y las ruedas magnéticas evitan la separación de las ruedas y por lo tanto los vagones de los raíles. En el caso de usar electroimanes su alimentación puede ser variable de forma que se regule y aumente su atracción en los tramos más peligrosos, curvas o cuando se detecte que las ruedas se separan en exceso de los raíles. Para esto unos sensores miden constantemente la separación entre ruedas y raíles. En una variante los electroimanes se alimentan secuencialmente atrayendo solo los que están en la zona de avance, lo cual además de proteger del descarrilamiento, permite avanzar al girar la rueda. Con los electroimanes se puede aplicar un flujo electromagnético giratorio.In all cases the wheels surround and catch the rails and the magnetic wheels prevent the separation of the wheels and therefore the wagons from the rails. In the case of using electromagnets, their power supply can be variable so as to regulate and increase their attraction in the most dangerous sections, curves or when it is detected that the wheels are too far apart from the rails. For this, sensors constantly measure the separation between wheels and rails. In a variant, the electromagnets are fed sequentially, attracting only those in the advance zone, which, in addition to protecting from derailment, allows moving forward when the wheel rotates. With electromagnets a rotating electromagnetic flux can be applied.
En todos los casos puede añadir unas ruedas que en caso de elevación excesiva de los vagones tocan en las cabezas de los raíles y hacen de retén. También pueden servir de aviso de elevación excesiva de las ruedas o los vagones, mandando una señal para que los electroimanes aumenten su atracción.In all cases, you can add wheels that, in case of excessive lifting of the wagons, touch the heads of the rails and act as a catch. They can also serve as a warning of excessive lifting of the wheels or wagons, sending a signal for the electromagnets to increase their attraction.
En los raíles de cabeza hueca, esta puede utilizarse para introducir un fluido y controlar la temperatura de los raíles evitando su dilatación o contracción.In the hollow head rails, this can be used to introduce a fluid and control the temperature of the rails avoiding their expansion or contraction.
