Abstract

L'invention concerne les dispositifs de suspension pour organes mécaniques. Elle a pour objet un dispositif de suspension comprenant un flasque 17 solidaire de l'organe à suspendre. Ce flasque est relié à des ferrures fixes 20a, b et 21a, b par des plots souples 18a, b et 19a, b, travaillant en compression, et par un systeme articulé déformable composé de bielles 24a, b et 25a, b et d'une traverse 30, ce système procurant une liaison rigide en rotation et assurant la reprise d'un couple dont ledit organe est le siège. Application à la suspension, avec filtrage des vibrations, de la boîte de transmission principale d'un giravion sur son fuselage.
