Abstract

The train brake pads for the top of the tracks and for their sides, are a way to increase the effectiveness of the brakes of a train in the solution proposed in my patent titled: train brake directed to the tracks, improved. If there was to create a brake that was distributed throughout all the cars and could contact the tracks at a given time, now it is about making the brake pads not only cover the top or top of the track, but which may also cover the largest possible contact area along the sides of the tracks. To do this, a mechanism is built that takes advantage of the lowering of the brake to lower the lateral brake pads at the same time. (Machine-translation by Google Translate, not legally binding)

Descripción de la invenciónDescription of the invention

Las Pastillas de freno de tren para la cima de las vías y para sus laterales, son un mecanismo con el que se trata de conseguir una mayor efectividad en la frenada al aumentar la superficie de contacto con las vías por parte de las pastillas de caucho. Se trata de hacer que otras pastillas laterales (2), -ademas de las pastillas (3) que se ponen en la cima de la vía (1)-, puedan también entrar en contacto con los laterales y el hueco de estas vías (1). Para este cometido se crea un sistema que tiene un tubo (12) que se prolonga en un segmento hueco (10). En su interior hay un eje dentado (5), con un tope en la parte superior, y un muelle (9) encima del tope. Fijadas en el interior del hueco del tubo (10), hay unas ruedas dentadas (6, 7, 8), que se moverán cuando el tubo (10) empiece a descender ya que la rueda (6) se halla en conexión con los dientes del eje (5). Por tanto, cuando desciende todo el mecanismo de freno, la pastilla (3) de la cima de la vía se pone en contacto con esta vía antes de que acabe de descender el tubo (10). Mientras desciende este tubo (10), las ruedas dentadas de su interior, al girar, harán que desciendan los soportes metálicos (4) que llevan las pastillas de freno laterales (2), hasta que entran en contacto con las vías (1), tal como se muestra en la figura nº 1. Esta mayor superficie de contacto, de las pastillas de freno, con las vías, dotará de mayor poder a la frenada y contribuirá a que el tren quede detenido en el menor espacio posible. Cuando el piloto suelte el pedal del freno, las pastillas laterales (2) y la de la cima (3), se liberarán de su posición de frenado, el tubo (12) ascenderá, y con él, el segmento inferior hueco (10) del mecanismo. Entrará en acción también el muelle (9) que hará que el eje dentado (5) descienda porque caerá por su propio peso, ya que no se halla fijado en el hueco del tubo (10). Así, al descender, o, al ascender el tubo (10), esto hará rodar, -en sentido contrario al anterior-, a las ruedas dentadas (6) que se hallan en contacto con las ruedas dentadas (7, 8), de los soportes metálicos (4) de las pastillas laterales, con lo que los soportes se separarán de las vías hasta la próxima exigencia de los frenos del tren. En la figura nº 2 se dibuja una variante del freno anterior. Hay en ella, como antes, un tubo (12), que está hueco en el segmento inferior (10). Del hueco inferior cuelga el eje (5), con su tope (14), y la pastilla de freno (3). Cuando el piloto acciona el pedal de frenado, el tubo (12) desciende y la pastilla de freno (3) llegará a tocar la cima de la vía (1) antes de que el tubo (10) Llegue a su posición más descendida, o sea, hasta que toque la parte superior de la pastilla de freno (3). Mientras desciende el tubo (10), los soportes metálicos (4) de las pastillas de freno laterales (2), -ya que tienen esa forma peculiar en el segmento que se halla en el interior del tubo (10)-, tropezarán con el tope (14) del eje (5), -mientras pivotan sobre el punto (15)-, y harán que los soportes metálicos (4) hagan que las pastillas de freno (2) laterales que están en su interior, se introduzcan en el hueco de las vías, con lo que aumentará así la superficie de contacto de la frenada y el tren se detendrá antes que con los métodos actuales. Después, cuando el piloto libera el pedal del freno, el tubo (12) asciende, y, con 61, asciende también el tubo hueco (10). La pastilla de freno de la cima (3) permanecerá aún en contacto con la vía, hasta que la parte inferior del tubo (10) ascienda lo suficiente y tropiece con el tope (14) del eje (5). Esto hará que, sólo en ese momento, la pastilla de freno (3) y su eje (5) empiecen a ascender. Al mismo tiempo, los soportes metálicos (4) se librarán de la presión a la que estaban sometidos y entrarán en acción los muelles (9) laterales que harán que asciendan, hasta su posición de reposo, las pastillas de freno laterales (2). Aquí, los muelles (9) que devuelven a su posición a las pastillas laterales de freno, son exteriores al tubo (10) y se sostienen en una barra metálica (13) perpendicular al segmento inferior del tubo (10). Fecha de la invención: (15.II.05).The train brake pads for the top of the tracks and for their sides , are a mechanism with which it is to achieve greater effectiveness in braking by increasing the surface of contact with the tracks by the rubber pads. It is about making other lateral pads (2), - also the pads (3) that are placed at the top of the track (1) -, can also come into contact with the sides and the hollow of these tracks (1 ). For this purpose, a system is created that has a tube (12) that extends into a hollow segment (10). Inside there is a toothed shaft (5), with a stop at the top, and a spring (9) above the stop. Fixed inside the hollow of the tube (10), there are sprockets (6, 7, 8), which will move when the tube (10) begins to descend since the wheel (6) is in connection with the teeth of the shaft (5). Therefore, when the entire brake mechanism descends, the pad (3) of the top of the track is contacted with this track before the tube (10) has just descended. While descending this tube (10), the internal gearwheels, when turning, will cause the metal supports (4) that carry the lateral brake pads (2) to descend, until they come into contact with the tracks (1), as shown in figure 1. This larger contact surface, of the brake pads, with the tracks, will give more power to the braking and will contribute to the train being stopped in the smallest possible space. When the pilot releases the brake pedal, the side pads (2) and the one of the top (3), will be released from their braking position, the tube (12) will ascend, and with it, the hollow lower segment (10) of the mechanism. The spring (9) will also take action, which will cause the toothed shaft (5) to descend because it will fall by its own weight, since it is not fixed in the hollow of the tube (10). Thus, when descending, or, when ascending the tube (10), this will cause, in the opposite direction to the previous one, the sprockets (6) that are in contact with the sprockets (7, 8), of the metal supports (4) of the side pads, whereby the supports will be separated from the tracks until the next requirement of the train brakes. A variant of the previous brake is drawn in figure 2. There is, as before, a tube (12), which is hollow in the lower segment (10). The shaft (5), with its stop (14), and the brake pad (3) hangs from the lower hole. When the pilot operates the brake pedal, the tube (12) descends and the brake pad (3) will touch the top of the track (1) before the tube (10) reaches its lowest position, or either, until you touch the top of the brake pad (3). While the tube (10) descends, the metal supports (4) of the side brake pads (2), - since they have that peculiar shape in the segment inside the tube (10) -, will trip over the butt (14) of the shaft (5), - while pivoting on the point (15) -, and will make the metal brackets (4) make the side brake pads (2) that are inside, are introduced into the hollow of the tracks, thereby increasing the contact surface of the braking and the train will stop before the current methods. Then, when the pilot releases the brake pedal, the tube (12) rises, and, with 61, the hollow tube (10) also rises. The top brake pad (3) will still remain in contact with the track, until the bottom of the tube (10) rises sufficiently and runs into the shaft stop (14) (5). This will cause, only at that time, the brake pad (3) and its axle (5) begin to rise. At the same time, the metal supports (4) will be relieved of the pressure to which they were subjected and the lateral springs (9) will come into action that will cause the lateral brake pads (2) to ascend to their resting position. Here, the springs (9) that return the lateral brake pads to their position are external to the tube (10) and are held in a metal bar (13) perpendicular to the lower segment of the tube (10). Date of the invention: (15.II.05).

Descripción de un modo de realización preferidaDescription of a preferred embodiment

Las Pastillas de freno de tren para la cima de las vías y para sus laterales, son un complemento de las pastillas de freno (3) que se limitan a entrar en contacto con la parte superior de las vías (1). Están situadas en el segmento inferior del tubo hueco (10) que se prolonga desde el tubo (12) que desciende cuando el piloto acciona el pedal de freno. En el interior del tubo hueco (10) hay un eje dentado (5) que tiene un tope en la parte superior. En la parte inferior de este eje se sitúa la pastilla de freno (3) dirigida a la cima de la vía. En contacto con los dientes del eje (5) se hallan unas ruedas dentadas (6) a ambos lados del eje (5), que se hallan en conexión con otras ruedas dentadas (7) más pequeñas, que cambian el sentido del giro y se hallan en contacto con otras ruedas dentadas (8) que se hallan en los soportes metálicos (4) de las pastillas de freno laterales (2). Estas pastillas (2) tienen una forma adecuada a la zona a la que van destinadas, es decir, en los laterales y en el hueco de las vías (1). Así, forman cada una de ellas, una especie de letra "L" y otra "L" invertida hacia la izquierda, que se incrusta en el hueco cuando la acción de todo el freno las pone en contacto con las vías. Un muelle (9), -en la parte superior del tope del eje (5)-, se encarga de hacer descender el eje dentado (5) cuando se libera el freno de su contacto con las vías. Esto hace que el tubo (10) ascienda y, a la vez, el eje (5) descenderá por la acción del muelle (9), lo que hará girar, ahora en sentido contrario a las ruedas dentadas (6, 7, 8) y separará las pastillas de freno de los laterales de las vías mientras el tubo (10) asciende y el eje y la pastilla de freno de la cima (3) desciende un poco hasta que el tope superior del eje impida que se salga del todo por la base del tubo.The train brake pads for the top of the tracks and for their sides , are a complement of the brake pads (3) that are limited to coming into contact with the top of the tracks (1). They are located in the lower segment of the hollow tube (10) that extends from the tube (12) that descends when the pilot operates the brake pedal. Inside the hollow tube (10) there is a toothed shaft (5) that has a stop at the top. The brake pad (3) directed to the top of the track is located at the bottom of this axis. In contact with the teeth of the axle (5) are sprockets (6) on both sides of the axle (5), which are in connection with other smaller sprockets (7), which change the direction of rotation and are they are in contact with other sprockets (8) that are in the metal supports (4) of the side brake pads (2). These pads (2) have a shape adapted to the area to which they are intended, that is, on the sides and in the hollow of the tracks (1). Thus, they form each of them, a kind of letter " L " and another " L " inverted to the left, which is embedded in the gap when the action of the entire brake puts them in contact with the tracks. A spring (9), -in the upper part of the shaft stop (5) -, is responsible for lowering the toothed shaft (5) when the brake is released from its contact with the tracks. This causes the tube (10) to rise and, at the same time, the shaft (5) will descend by the action of the spring (9), which will turn, now in the opposite direction to the sprockets (6, 7, 8) and it will separate the brake pads from the sides of the tracks while the tube (10) ascends and the axle and the brake pad from the top (3) descends slightly until the upper stop of the axle prevents it from coming out completely the base of the tube.

La variante de la figura nº 2 consiste en un mecanismo diferente, destinado al mismo segmento inferior del tubo (10), el que, al descender, presionará la pastilla de freno (3) de la cima de la vía (1) sobre ésta y la hará ascender un poco hacia el interior del tubo (10) del que parecía estar colgando. Eso hará que el tope (14) del eje (5), -que tiene sus extremos ligeramente inclinados-, ascienda y empuje los extremos de los soportes metálicos (4) de las pastillas de freno laterales (2), las cuales pivotarán sobre un eje (15) y presionaran las pastillas de freno sobre los laterales y el hueco de las vías. Después, cuando se libere la presión de la frenada, el tubo (10) ascenderá y la pastilla de freno de la cima de la vía descenderá hasta su posición original, colgando un poco del tubo y eso liberará el espacio oportuno para que los extremos de los soportes metálicos de los frenos laterales (4) puedan volver a su posición original merced a la acción de los muelles (9) de las barras metálicas (13) que sobresalen en perpendicular al tubo (10). Esto separará las pastillas laterales de las vías y las mantendrá así hasta su nueva presión hacia ellas por la acción de la frenada.The variant of figure 2 consists of a different mechanism, intended for the same lower segment of the tube (10), which, when descending, will press the brake pad (3) of the top of the track (1) over it and will make it ascend a little towards the inside of the tube (10) from which it seemed to be hanging. That will do that the end stop (14) of the shaft (5), which has its ends slightly inclined-, raise and push the ends of the supports metal (4) of the side brake pads (2), which will pivot on an axle (15) and press the brake pads on the sides and the hollow of the tracks. After when release the braking pressure, the tube (10) will rise and the brake pad from the top of the track will descend to its position original, hanging a little from the tube and that will free up the space suitable for the ends of the metal supports of the side brakes (4) can return to their original position thanks to the action of the springs (9) of the metal bars (13) that protrude perpendicular to the tube (10). This will separate the side track pads and keep them that way until your new pressure towards them by the braking action.
