Abstract

La transmission selon l'invention comprend deux trains planétaires 11 et 12 comportant respectivement des pignons centraux 13 et 14, des couronnes dentées 15 et 16 et des porte-trains 17 et 18 avec des engrenages satellites 19 et 20. Un variateur de vitesse 30 est accouplé à l'arbre d'entrée 21 et au pignon central 13 du premier train 11. Le variateur comprend deux groupes pompe-moteur 32 et 33. L'arbre d'entrée peut également être accouplé par un premier embrayage 23 au porte-train 17 du premier train planétaire et par un deuxième embrayage 24 au pignon central 14 du deuxieme train planétaire. Un frein 36 peut bloquer le porte-train 17 dans la première gamme de vitesse ainsi qu'en marche arrière. Applications : entre autres, véhicules automobiles, matériel agricole et de construction, machines-outils.
