Abstract

La présente invention concerne un dispositif amortisseur à friction comprenant au moins deux ensembles (100, 200) susceptibles de déplacement relatif guidés, l'un lié à une référence fixe, l'autre mobile, un organe intermédiaire (300) en appui contre l'un premier (100) des ensembles et susceptible de déplacement relatif par rapport à ce premier ensemble avec friction sous l'effet d'un effort appliqué, des moyens élastiques (400) qui agissent sur l'organe intermédiaire,caractérisé par le fait que les moyens élastiques (400) sollicitent au repos ledit organe intermédiaire (300) en appui sur le premier ensemble (100) et que le dispositif comprend en outre des moyens de commande (500) disposés entre l'organe intermédiaire (300) et le deuxième ensemble (200), tel que dans un premier sens de déplacement relatif entre les deux ensembles (100, 200) le déplacement relatif entre ceux-ci soit freiné par un effort de friction défini par les moyens élastiques (400), tandis que dans le deuxième sens de déplacement relatif entre les deux ensembles (100, 200), les moyens de commande (500) agissent sur les moyens élastiques (400) pour modifier l'effort exercé sur l'organe intermédiaire (300).
