Abstract

Ressort travaillant à la compression et au cisaillement constitué d'un corps cylindrique creux en matière à élasticité caoutchoutique dont la cavité, fermée sur les deux côtés frontaux, est remplie de liquide. Ce ressort possède une rigidité élevée dans la direction de l'axe du cylindre et une faible rigidité dans les directions transversales. Pour obtenir une caractéristique d'élasticité progressive, une bulle de gaz ou de vapeur peut se trouver dans le liquide remplissant la cavité Ce ressort est utilisable en particulier sur les véhicules sur rails comme ressort de compression, l'axe du cylindre étant disposé dans la direction de marche pour la transmission, du bogie à la caisse, des forces d'accélération qui apparaissent au démarrage et au freinage
