Title (EN) DEVICE FOR STORING AND RESTORING MECHANICAL ENERGY
(FR) DISPOSITIF DE STOCKAGE ET DE RESTITUTION D'ÉNERGIE MÉCANIQUE
Abstract: front page image
(EN) The invention relates to a device for storing and restoring mechanical energy, comprising: first and second drums (T1, T2) having parallel axes substantially opposite each other; a resilient means (7) that can be wound over the periphery of each of said drums; said axes being coupled by coupling means (3, 4, 6) such that the rotation of one drum results in a proportional angular rotation of the other, and such that the linear speed at the periphery of the first drum (T1) is higher than at that of the second drum (T2). The invention also relates to a propulsion system comprising two devices for storing and restoring energy.
(FR) L'invention porte sur un dispositif de stockage et de restitution d'énergie mécanique comportant : - un premier et un second tambours (T1, T2) d'axes parallèles et sensiblement en regard l'un de l'autre, - un moyen élastique (7) apte à s'enrouler sur la périphérie de chacun desdits tambours, - lesdits axes étant couplés par des moyens de couplage (3, 4, 6) de telle sorte que la rotation d'un tambour entraîne la rotation angulairement proportionnelle de l'autre, et que la vitesse linéaire à la périphérie du premier tambour (T1) soit supérieure à celle du second tambour (T2). L'invention porte également sur un système de propulsion comportant deux dispositifs de stockage et de restitution d'énergie.
