Abstract

L'invention concerne un dispositif mécano-hydraulique pour charge soumise à des chocs et vibrations. Il comprend un ensemble vis 1-écrou 3, dont l'un des éléments est susceptible de se déplacer en translation axiale par rapport à un corps 5, dans lequel l'autre élément est monté en rotation et commande l'entraînement d'un rotor d'un dispositif de freinage hydraulique laminaire 72, de faible capacité et porté par le corps 5, de sorte que tout déplacement de celui des éléments de l'ensemble vis 1-écrou 3, qui est animé d'une translation axiale, soit transformé par l'autre en une rotation entraînant un freinage hydraulique complémentaire du freinage inertiel. Application à la stabilisation des charges suspendues, telles que les tuyauteries.
