Abstract

L'invention propose un dispositif (12) d'entraînement d'un axe (14), caractérisé en ce qu'il comporte un bâti fixe (18), un chariot d'entraînement (20) guidé en coulissement axial (A), une vis (22) d'entraînement du chariot, un moteur (24) d'entraînement de la vis, un écrou d'entraînement (26) monté sur la vis d'entraînement ; un ressort d'assistance (28) qui est monté entre le chariot (20) et l'écrou (26), qui, sous l'action de l'écrou d'entraînement (26) est apte à accumuler de l'énergie, et qui, lors d'une course axiale du chariot (20) par rapport au bâti (18), est apte à restituer l'énergie accumulée au chariot d'entraînement (20).
