Abstract

L'invention concerne un système et un élément intermédiaire destiné à un système (1, 1') servant à fixer sur un support (U) un rail (S) pour un véhicule ferroviaire. L'élément intermédiaire (12, 12') est prévu pour être agencé entre une partie d'extrémité (7, 8) d'un élément ressort (3, 3') et le rail (S), de sorte que l'élément ressort (3, 3') transmet une force de retenue (N, N') sur le rail (S) par l'intermédiaire de l'élément intermédiaire (12, 12'). L'élément intermédiaire (12, 12') comporte une surface d'appui (14) sur laquelle la partie d'extrémité (7, 8) de l'élément ressort (3, 3') se trouve pendant l'utilisation du système, et une surface de support (22) par laquelle il porte sur le rail (S) pendant l'utilisation du système. Selon l'invention, l'élément intermédiaire (12, 12') est réalisé pour être déformable élastiquement dans une direction d'action (W) orientée de la surface d'appui (14) vers la surface de support (22). L'incorporation d'un élément intermédiaire (12, 12') selon l'invention dans un système de fixation de rails permet de réduire au minimum le risque que la durée de vie de l'élément ressort (3, 3') utilisé dans le système pour maintenir le rail ne soit raccourcie en raison de mouvements périodiques.
