Abstract

La présente invention concerne un élément de transmission de force (10) élastique, en particulier pour la transmission de couples de rotation, l'élément de transmission de force (10) étant doté d'au moins deux ouvertures de réception (14, 16) pour la liaison avec des composants de transmission de force, d'un corps élastomère (12) et d'au moins un ensemble de boucles (26) intégré dans le corps élastomère (12). L'ensemble de boucles présente au moins deux brins opposés (42, 44) et l'élément de transmission de force (10) présente au moins un dispositif d'absorption de pression (28, 30, 36, 38). Selon l'invention, il est prévu que l'au moins un dispositif d'absorption de pression (28, 30, 36, 38) soit placé dans une zone entre les brins opposés (42, 44) de l'ensemble de boucles (26), dans laquelle les brins opposés (42, 44) de l'ensemble de boucles (26) présentent la plus grande distance (A) l'un par rapport à l'autre. L'au moins un dispositif d'absorption de pression (28, 30, 36, 38) est formé de sorte que la rigidité de l'élément de transmission de force (10) augmente progressivement sous une charge de traction.
