<p>A supporting device for railway rails comprises a sleeper (1) and a socket (2) for encasing the sleeper. The socket includes, at a predetermined distance from each other, two areas (13 and 14) for contact with the sleeper. The first area (13) is formed by the free end (7) of the lateral wall (4) of the socket, the second (14) by a peripheral bead (11) having a predetermined dynamic stiffness. The inner surface (16) of the lateral wall (4) is inclined towards the inside of the socket from a zone (12) located at the height of the bead (11). An anti-vibration pad (15) made of a material having a determined dynamic stiffness is advantageously placed under the sleeper. <IMAGE></p> |
