Abstract

La présente invention consiste à convertir une bielle amortissante en bielle rigide en cas de vibrations anormale. La bielle amortissante comprend un corps (10) présentant une cavité (12) et une tige (8) à l'intérieur de ladite cavité, la bielle comprenant une chape (22) associée au corps (10) et permettant la fixation à un élément. La tige peut se déplacer à l'intérieur du corps ou le corps autour de la tige. La bielle comporte des moyens (38) d'immobilisation de la tige par rapport à la chape (22) comprenant au moins un crochet (52) et au moins une excavation (66), respectivement portés par deux pièces de la bielle susceptibles de se déplacer l'une vers l'autre et de forme telle que avec le déplacement des pièces longitudinalement l'une par rapport à l'autre, le crochet entrainé dans l'excavation en correspondance immobilise la tige par rapport à la chape.
