Abstract
Este sistema de freno consiste en un freno electroimán o hidráulico que acciona un eje cuadrado, terminado en una cuña, y una pieza metálica rectangular, que cuando el tren va en marcha, está subida. Al percatar un obstáculo que se encuentre en la vía, se acciona el sistema electroimán o hidráulico y la pieza rectangular se empuja contra el raíl, produciendo así la frenada rápida del tren, a base de rozamiento, amortizando más rápidamente la frenada del tren. El freno del tren ha de estar conectado al mismo tiempo en ruedas y en estas piezas de freno, que habrá 4 por vagón, distribuidas 2 por cada lado.This brake system consists of an electromagnet or hydraulic brake that drives a square shaft, finished in a wedge, and a rectangular metal part, which when the train is running, is up. When an obstacle is detected on the track, the electromagnet or hydraulic system is activated and the rectangular piece is pushed against the rail, thus causing rapid braking of the train, based on friction, more quickly amortizing the braking of the train. The train brake must be connected at the same time on wheels and on these brake parts, which will be 4 per car, distributed 2 on each side.
Description
Sistema de freno en corta distancia, para todos los trenes, principalmente de alta velocidad.Short distance brake system, for all the trains, mainly high speed.
La invención se encuadra en el sector técnico de frenos de trenes, más concretamente en sistema de frenada rápida por rozamiento entre pieza-raíl.The invention falls within the technical sector of train brakes, more specifically in rapid braking system by friction between piece-rail.
Actualmente, el sistema de frenado de trenes consiste en un sistema de rozamiento rueda-raíl. Es un freno limitado en cuanto a que la superficie de rozamiento es bajo, y por lo tanto, la distancia de frenada es mayor, y el tiempo de reacción de frenado es alto.Currently, the train braking system It consists of a wheel-rail friction system. Is a limited brake in that the friction surface is low, and therefore, the braking distance is longer, and the time Braking reaction is high.
Sería por lo tanto deseable que el tiempo de reacción de freno fuese menor, porque así en el caso de frenada urgente por cualquier obstáculo que se encuentre en la vía, o bien venga un tren de cara, vagón parado, piedras, etc., se evitaría colisión y por tanto pérdida de vidas humana así como desperfectos del tren.It would therefore be desirable that the time of brake reaction was less, because in the case of braking urgent for any obstacle that is in the way, or come a face train, wagon stopped, stones, etc., would be avoided collision and therefore loss of human life as well as damage of the train.
Para ello, la presente invención se centra en una mayor superficie de rozamiento, y una distancia de frenada menor con el consiguiente tiempo de reacción de frenada bajo.For this, the present invention focuses on a greater friction surface, and a shorter braking distance with the consequent low braking reaction time.
La presente invención se refiere a un nuevo sistema de freno, a corta distancia para trenes, principalmente de alta velocidad, consistente en una pieza metálica accionada por un sistema hidráulico o electroimán, que cuando el tren va en marcha, la pieza está subida, y cuando se acciona el freno, la pieza tiene un corto recorrido (distancia de la pieza al raíl a convenir) hasta llegar en contacto con el raíl, de manera que roza con él, y así se amortiza una frenada más rápida, en caso de frenada urgente, por cualquier obstáculo que se encuentre en la vía, o bien venga un tren de cara, vagón parado, piedras, etc., evitando así pérdidas de vidas humanas así como desperfectos del tren.The present invention relates to a new brake system, short distance for trains, mainly of high speed, consisting of a metal part driven by a hydraulic system or electromagnet, which when the train is running, the part is up, and when the brake is applied, the part has a short distance (distance from the piece to the rail to be agreed) until get in contact with the rail, so that it rubs against it, and so amortizes faster braking, in case of urgent braking, by any obstacle that is on the track, or a train comes of face, wagon stopped, stones, etc., thus avoiding loss of life human as well as train damage.
La presión hidráulica o electroimán que ejerce la pieza sobre el raíl, no puede ser la presión total que ejerce el vagón sobre el raíl, porque sino levitaría, por lo tanto, la presión ha de ser de un 75% del peso del vagón o similar.The hydraulic or electromagnet pressure it exerts the piece on the rail cannot be the total pressure exerted by the wagon on the rail, because otherwise it would levitate, therefore, the pressure It must be 75% of the weight of the car or similar.
La presión ha de estar dividida en 4, por lo consiguiente, habrán 4 piezas por vagón, distribuidas 2 por cada lado.The pressure must be divided into 4, so consequently, there will be 4 pieces per car, distributed 2 for each side.
El eje principal de la pieza es cuadrado, se ha descartado que fuera redondo para eliminar posibles movimientos.The main axis of the piece is square, it has ruled out that it was round to eliminate possible movements.
Los extremos de la pieza de frenado rectangular van en cónico o media luna, para que la pieza no reciba un golpe seco al paso por las juntas de vía.The ends of the rectangular braking part they are in conical or half moon, so that the piece does not receive a blow Dry as it passes through the track joints.
El freno ha de estar conectado tanto en las ruedas como en las piezas de freno, al mismo tiempo, es decir, no seria efectivo si sólo se accionase la pieza de frenado.The brake must be connected to both the wheels as in the brake parts at the same time, that is, no It would be effective if only the braking part was operated.
Al ser éste un sistema de frenado a poca distancia y muy rápido, podría provocar una fuerte sacudida a los viajeros pudiendo suponer un peligro para su salud. Para ello sería conveniente poner unos cinturones en los asientos como los automóviles, previo señal acústico al accionarse el freno, para alertar a los pasajeros.Since this is a slow braking system distance and very fast, could cause a strong shake at travelers may pose a danger to their health. This would be convenient to put some seat belts like cars, after acoustic signal when the brake is applied, to alert passengers.
Si los pasajeros no están sentados, debe haber por el pasillo de arriba a abajo, un pasamán, para que en caso de frenada brusca, puedan sujetarse.If the passengers are not seated, there must be down the hall from top to bottom, a balaclava, so that in case of sudden braking, can be held.
Para los que se encuentren en presencia de delante de una puerta, ésta podría ir recubierta de cojín o enboatada, así como el cuarto de baño, para que los viajeros no sufran daños al abalanzarse sobre ellos.For those who are in the presence of in front of a door, it could be covered with cushion or crushed, as well as the bathroom, so that travelers do not suffer damage by pouncing on them.
El sistema de freno de emergencia consiste en una pieza de recinto (1) que va situada debajo del vagón, en vertical con la vía, donde se ubicarán los tubos de presión hidráulica o electroimán de entrada y salida (2) y el tubo de agua de refrigeración (3), y que accionará un eje cuadrado móvil (4) al final del cual se sitúa la pieza rectangular (5) propiamente de frenado, que tendrá el mismo ancho que el raíl. Esta pieza irá sujetada con el eje cuadrado por un refuerzo romboidal (6) a fin de tener una mayor estabilidad.The emergency brake system consists of a piece of enclosure (1) that is located under the wagon, in vertical with the track, where the pressure pipes will be located Hydraulic or electromagnet inlet and outlet (2) and water pipe of cooling (3), and that will drive a mobile square axis (4) to the end of which the rectangular piece (5) proper of braking, which will be the same width as the rail. This piece will go fastened with the square axis by a rhomboid reinforcement (6) in order to have greater stability
Se han proyectado a ambos lados de la pieza de frenado, y sujetos con la pieza de recinto, unos tubos de salida de agua (7) a modo de refrigeración, para impedir posibles incendios laterales de la vía al producirse las chispas propias de frenado de la pieza contra el raíl. Estas salidas de agua se proyectarán a los laterales de la pieza, de manera que el agua salga con inclinación para no mojar los raíles.They have been projected on both sides of the piece of braking, and subject to the enclosure piece, outlet pipes of water (7) by way of cooling, to prevent possible fires side of the track when the own braking sparks of the piece against the rail. These water outlets will be projected at sides of the piece, so that the water comes out with inclination so as not to wet the rails.
La pieza de frenado tendrá dos posiciones: La posición elevada (Posición 1), cuando el tren va en marcha, y la posición de frenado (Posición 2), cuando se acciona el freno de emergencia, al mismo tiempo de ruedas y pieza.The braking part will have two positions: elevated position (Position 1), when the train is running, and the braking position (Position 2), when the brake is applied emergency, at the same time of wheels and piece.
