Abstract

L'invention concerne un élément en élastomère-métal pour un palier en élastomère-métal, en particulier servant de jonction de palier entre un module à coupole et un véhicule, comprenant : un élément métallique cylindrique intérieur (2) pour la liaison avec un premier composant à supporter, deux éléments en coque de tôle extérieurs (4, 5; 4', 5'), opposés entre eux, chevauchant partiellement l'élément métallique cylindrique intérieur, et des corps en élastomère adhérents (6, 7, 8, 9), entre l'élément métallique intérieur (2) et les éléments en coque de tôle (4, 5; 4', 5'), l'élément élastomère-métal (1) pouvant être compressé sur un second composant à supporter, par application d'une précontrainte radiale dans les corps en élastomère (6, 7, 8, 9), dans un oeilleton de réception (19). L'invention est caractérisée en ce qu'il est prévu une butée de rotation (16, 17 avec 13, 20) qui, au-delà d'un moment de libération de butée déterminé, au cours duquel le palier en élastomère-métal (1) présente une rigidité à la torsion relativement élevée, tout en ayant des caractéristiques élastiques de torsion approximativement linéaires, peut être compressée avec relâchement du support de butée, ce qui permet d'absorber une déflexion de torsion ultérieure ayant une caractéristique élastique de torsion horizontale ou décroissante.
