Abstract

L'invention se rapporte à l'industrie mécanique et peut s'utiliser pour déterminer la dépendance de la déformation de différents éléments de ressort de la charge appliquée; elle peut également s'utiliser dans des mécanismes d'horlogerie, dans de différents systèmes d'ouverture, en tant que suspensions sans à-coups ou en industrie automobile. L'élément de ressort à force de déformation non linéaire se présente comme un profil ayant une section prédéterminée; en coupe transversale, cet élément a une forme ondulée. L'invention concerne aussi une structure à ressort qui comprend l'élément de ressort mentionné ici dont une extrémité est reliée rigidement à un corps en forme de tambour et l'autre extrémité est reliée à l'axe, ainsi qu'un procédé de transmission d'effort à travers l'élément de ressort par sa déformation, la déformation étant accompagnée d'une perte de stabilité de l'élément de ressort. L'invention permet d'obtenir une forme de l'élément de ressort qui ne limite pas les dimensions ou le matériau de l'élément de ressort et possède une rigidité élevée.
