(EN) WIDE-RANGE CONTINUOUSLY VARIABLE-RATIO DRIVE
(FR) ENTRAINEMENT A VARIATION EN CONTINU A GAMME ETENDUE
Abrégé
(EN)
The invention relates to mechanical engineering and can be used for transport mechanical engineering, in particular in the form of a continuously variable gearbox for motor vehicles and other transport means. The inventive continuously variable-ratio drive consists of a planetary variable-ratio transformer provided with input and output links which are cinematically connected to each other by means of a control mechanism provided with a differential transmission unit. A matching transmission unit which connects the output link of the variable ratio transformer to one of the central gears of the differential transmission unit and increases a rotational velocity in this direction is arranged in the cinematic loop of the mechanism between the input and output links of the variable ratio transformer. The gear ratio value of the matching transmission unit is equal to or higher than the minimum gear ratio value of the variable ratio transformer. The output link of the entire drive is embodied in such a way that it is alternately connectable to the links of the control mechanism which comprises the differential and matching transmission units when the rotational velocities of said links are equal.

L'invention appartient au domaine des constructions mécaniques et peut s'utiliser dans des constructions mécaniques destinées aux moyens de transport, notamment aux boîtes à vitesses d'automobiles ou d'autres véhicules de transport. L'entraînement à variation en continu comprend un variateur à gamme étendue avec des éléments d'entrée et de sortie, reliés cinématiquement par un mécanisme de commande, qui comprend une vitesse différentielle. La chaîne cinématique du mécanisme comprend, entre les éléments d'entrée et de sortie du variateur et la vitesse différentielle, une vitesse d'adaptation qui relie l'élément de sortie du variateur et l'une des roues centrales de la vitesse différentielle, et qui augmente la vitesse de rotation dans cette direction. Le rapport d'engrenage de la vitesse d'adaptation n'est pas inférieur à une valeur minimale du rapport d'engrenage du variateur, et l'élément de sortie de l'entraînement dans sa totalité permet sa connexion en alternance avec les éléments du mécanisme de commande, qui comprend les vitesses différentielles et d'adaptation destinées à égaliser les vitesses de rotation de ces éléments.
