Abstract

Resorte ignífugo para su uso en suspensiones primarias de bogies de vagones ferroviarios que comprende un núcleo que se encuentra unido a un muelle, el cual a su vez se encuentra unido a una pieza exterior, comprendiendo dicho resorte un elemento de protección de material ignífugo que por un extremo se une a la pieza exterior y por el otro extremo al núcleo, determinando un cubrimiento que protege al muelle frente al fuego y otros agentes externos como piedras, gravilla, arena, lluvia, hielo o nieve.Fire retardant spring for use in primary suspensions of railway wagon bogies comprising a core that is attached to a spring, which in turn is attached to an outer part, said spring comprising a protective element of fire retardant material that by one end joins the outer piece and at the other end the core, determining a covering that protects the pier from fire and other external agents such as stones, gravel, sand, rain, ice or snow.
