Abstract (en)

The relative speed control is provided by two coaxial bodies (1,2) each in cooperation with one the two moving parts. The coaxial bodies are coupled one to the other so they can rotate about a common axis (5). An electromagnetic damper (3) is fitted between the two coaxial bodies and is formed by an eddy current brake (31,32). The damper operates through a speed multiplier formed by epicyclic gear trains, which incorporate a torque limiting spring (12) or a friction cone.

Abstract (fr)

La présente invention concerne un dispositif de régulation de la vitesse d'un mouvement, en particulier du mouvement relatif entre deux éléments. Dispositif caractérisé en ce que le moyen électromagnétique (3) de régulation de la vitesse relative entre les deux corps (1 et 2) est monté sur l'axe central (5) commun à ces derniers, et en ce que la chaîne cinématique formée par les trains épicycloïdaux intègre un entraînement à limitation de couple (12). L'invention est plus particulièrement applicable dans le domaine du contrôle actif de mouvements relatifs d'éléments. <IMAGE>
