Title (EN) TRANSMISSION SYSTEM COMPRISING PLANETARY GEARS
(FR) SYSTEME DE BOITE DE VITESSES A TRAINS EPICYCLOIDAUX
Abstract:
(EN) The invention relates to a transmission system comprising planetary gears. The inventive system comprises: an input element, an output element which is coaxial to the input element, two planetary gear trains (4, 5), clutches for obtaining a plurality of transmission ratios, and a speed-increasing planetary gear train (6) for obtaining at least one additional speed. According to the invention, each clutch acts between (i) one element of one of the planetary gear trains and (ii) the earth element, the input element, the output element or another element of the planetary gear trains. Moreover, each planetary gear train comprises a sun gear and planet gears which are supported by a planet carrier. In addition, the speed-increasing gear train (6) comprises a plurality of stepped planet gears (21, 22).
(FR) Système de boîte de vitesses à trains épicycloïdaux, comprenant un élément d'entrée, un élément de sortie coaxial à l'élément d'entrée, deux trains épicycloïdaux (4, 5), des embrayages pour obtenir une pluralité de rapports de transmission, et un train épicycloïdal multiplicateur de vitesse (6) pour obtenir au moins une vitesse supplémentaire, chaque embrayage agissant entre d'une part un élément d'un desdits trains épicycloïdaux et d'autre part l'élément terre, l'élément d'entrée, l'élément de sortie ou un autre élément desdits trains épicycloïdaux, chaque train épicycloïdal comprenant un engrenage solaire, et des engrenages satellites supportés par un porte-satellites, le train multiplicateur (6) comprenant une pluralité d'engrenages satellites étagés (21, 22).
