Abstract
L'invention concerne des ensembles de paliers extrêmes pour des bielles articulées. Selon l'invention, les ensembles de paliers extrêmes comprennent au moins deux sections en élastomère, dont l'une, laminée, 101, 102, 103, 104, 106 est disposée entre un boîtier 36A et une extrémité 18D d'un organe de transmission de charge dont l'autre extrémité 18A est connectée à l'autre section, et ils réagissent à des charges et permettent des mouvements le long d'au moins un parmi trois axes mutuellement perpendiculaires. L'invention s'applique notamment aux hélicoptères.
