Abstract

Esta invención presenta una pastilla de freno de tipo flotante para uso en condiciones climáticas de lluvia o nieve, perteneciente al campo de la tecnología de frenos ferroviarios. La invención comprende: una placa soporte (1), que consiste en una estructura en forma de sector de corona circular con ambos extremos redondeados mediante transiciones de arco de circunferencia; una pluralidad de bloques de fricción (2), los cuales se conectan a la placa soporte (1) a través de una unión flotante; los bloques de fricción (2) se disponen en varias hileras paralelas al borde interior de la placa soporte (1) hasta llegar a su borde exterior; entre bloques de fricción de hileras adyacentes se coloca un mecanismo anti-rotación; la superficie de fricción de los bloques (2) consiste en una superficie plana. La presente pastilla de freno resuelve el problema técnico consistente en que las pastillas de freno existentes acumulan fácilmente polvillo producido por la fricción, el cual, durante el uso en condiciones de lluvia o nieve, se congela junto con la lluvia o nieve, formando grandes bloques de hielo y afectando el funcionamiento normal de la pastilla de freno.This invention features a floating brake pad for use in weather conditions of rain or snow, belonging to the field of railway brake technology. The invention comprises: a support plate (1), consisting of a structure in the form of a circular crown sector with both ends rounded by circumference arc transitions; a plurality of friction blocks (2), which are connected to the support plate (1) through a floating joint; the friction blocks (2) are arranged in several rows parallel to the inner edge of the support plate (1) until reaching its outer edge; an anti-rotation mechanism is placed between friction blocks of adjacent rows; The friction surface of the blocks (2) consists of a flat surface. The present brake pad solves the technical problem that existing brake pads easily accumulate dust produced by friction, which, during use in rainy or snowy conditions, freezes along with rain or snow, forming large blocks of ice and affecting the normal operation of the brake pad.

REALIZACIÓN ESPECÍFICA DE LA INVENCIÓN SPECIFIC EMBODIMENT OF THE INVENTION

A continuación se explica en más detalle la presente invención mediante el siguiente ejemplo de realización, junto con las figuras correspondientes. The present invention will be explained in more detail below by means of the following embodiment, together with the corresponding figures.

La figura 1 ilustra la pastilla de freno de tipo flotante para lluvia y nieve de la presente invención, la cual comprende: la placa soporte 1, que consiste en una estructura en forma de sector de corona circular con ambos extremos redondeados mediante transiciones de arco de circunferencia; una pluralidad de bloques de fricción 2, los cuales se conectan a la placa soporte 1 a través de una unión flotante; los bloques 2 se disponen en varias hileras a lo largo del borde interior de la placa soporte 1 hasta llegar a su borde exterior; entre bloques de fricción de hileras adyacentes se coloca un mecanismo anti-rotación; la superficie de fricción de los bloques 2 consiste en una superficie plana. Figure 1 illustrates the floating brake pad for rain and snow of the present invention, which comprises: the support plate 1, consisting of a circular crown-shaped structure with both ends rounded by arc transitions of circumference; a plurality of friction blocks 2, which are connected to the support plate 1 through a floating joint; the blocks 2 are arranged in several rows along the inner edge of the support plate 1 until reaching its outer edge; an anti-rotation mechanism is placed between friction blocks of adjacent rows; The friction surface of the blocks 2 consists of a flat surface.

Dado que la velocidad lineal del borde interior de la citada pastilla de freno es menor que la de su borde exterior, a fin de mantener un calentamiento uniforme de la superficie de fricción de la placa soporte, los bloques de fricción 2 se disponen en número creciente en hileras consecutivas paralelas al borde interior hasta alcanzar el borde exterior. En esta realización, tal como ilustra la figura 2, los bloques de fricción 2 son de forma similar y de igual tamaño. El número de bloques de fricción 2 dispuestos cerca del borde interior de la placa soporte 1 es menor que el de los dispuestos cerca de su borde exterior. La distancia entre bloques adyacentes está entre los 5 y los 20 mm. Since the linear speed of the inner edge of said brake pad is less than that of its outer edge, in order to maintain a uniform heating of the friction surface of the support plate, the friction blocks 2 are arranged in increasing number in consecutive rows parallel to the inner edge until the outer edge is reached. In this embodiment, as illustrated in Figure 2, the friction blocks 2 are similarly and of equal size. The number of friction blocks 2 arranged near the inner edge of the support plate 1 is smaller than that of those arranged near its outer edge. The distance between adjacent blocks is between 5 and 20 mm.

Con el fin de aumentar la uniformidad del calentamiento durante el funcionamiento de la pastilla de freno, según se puede apreciar en la figura 1, la placa soporte 1 está cubierta con bloques de fricción 2 a lo largo de todo radio con centro en el eje de rotación del disco de freno correspondiente a la pastilla de freno citada. In order to increase the uniformity of the heating during the operation of the brake pad, as can be seen in Figure 1, the support plate 1 is covered with friction blocks 2 along any radius centered on the axis of rotation of the brake disc corresponding to the mentioned brake pad.

Cada bloque de fricción 2 está ensamblado en caliente a partir de un cuerpo de fricción 21, una pieza de sujeción 22 y una placa de sostén 23; la superficie de fricción del cuerpo 21 del bloque 2 posee dos bordes rectos paralelos, unidos en ambos extremos mediante una transición de arcos de circunferencia; la placa de sostén 23 consiste en una chapa plana con una parte esférica en su parte central; su contorno exterior coincide con el del cuerpo de fricción 21, y su parte esférica constituye un soporte esférico; uno de los extremos de la Each friction block 2 is hot assembled from a friction body 21, a fastener 22 and a support plate 23; the friction surface of the body 21 of the block 2 has two parallel straight edges, joined at both ends by a transition of circumferential arcs; the support plate 23 consists of a flat plate with a spherical part in its central part; its outer contour coincides with that of the friction body 21, and its spherical part constitutes a spherical support; one end of the
