Abstract

The mechanism has two notched or non-notched convex cones that are coupled in direction or opposite directions by an endless screw.

Description

1 1) INDICATION DU DOMAINE TECHNIQUE 1 1) INDICATION OF THE TECHNICAL FIELD

L'invention se situe dans le domaine mécanique, d'engrenages: c'est un convertisseur de couple à variation continue, sans changement de pignons. 2) ETAT DE LA TECHNIQUE ANTERIEURE The invention lies in the mechanical field of gears: it is a continuously variable torque converter, without change of gears. 2) STATE OF THE PRIOR ART

Les transferts de couples se font, boite manuellement, par courroies, par boites de transfert, par boites sequentielles. The transfers of couples are done, box manually, by belts, by boxes of transfer, by sequential boxes.

3) EXPOSE DE L'INVENTION 3) SUMMARY OF THE INVENTION

Les deux cônes bombés sont munies de la même denture, du même nombre de dents, du plus grand diamètre, au plus petit, travaillant ensemble, et positonnés dans le même sens, ou en sens opposés, comme indiqué au schémas 1. The two convex cones are provided with the same toothing, the same number of teeth, the largest diameter, the smallest, working together, and positron in the same direction, or in opposite directions, as shown in Diagrams 1.

En prenant l'exemple, d'une boîte automatique, pour automobile, un cône est relié au moteur par l'intermédiaire d'engrenages, et, ou, de cardans, prenant en considération, les déplacements des cônes bombés haut / bas, avant / arrière, l'autre à la transmission, et, ou à la roue. Taking the example of an automatic transmission, for automobile, a cone is connected to the engine via gears, and / or gimbals, taking into account the displacements of the curved cones up / down, before / rear, the other to the transmission, and, or to the wheel.

Le mécanisme peut constituer, en l'accouplement d'un cône convexe cranté, à une ou plusieurs vis sans fin, à pas unique ou variable.The mechanism may constitute, in the coupling of a notched convex cone, one or more endless screws, with single or variable pitch.
