Title (EN) AUTOMATIC TRANSMISSION
(FR) TRANSMISSION AUTOMATIQUE
Abstract:
(EN) An automatic four forward transmission with a length in the axial direction and the weight thereof not increased, wherein; the automatic transmission is constituted by a single planetary gear (10), a dual planetary gear (11) provided adjacent to said gear, in which a sun gear is formed integrally therewith and a carrier is integrally connected thereto, an input shaft (15), and a clutch (C3) for engaging the input shaft (15) with the ring gear of the single planetary gear (10) or disengaging the former from the latter through a connecting member (16); the connecting member (16) is connected to the ring gear of the dual planetary gear (11) through a clutch (CO), a brake (B1) for engaging or disengaging the sun gear and a brake (B2) for engaging or disengaging the ring gear of the dual planetary gear (11) are provided, and an output gear (13) is provided on the carrier.
(FR) Une transmission automatique pour quatre roues motrices a une longueur axiale et un poids réduits. La transmission automatique comprend un engrenage planétaire simple (10), un engrenage planétaire double (11) adjacent à l'engrenage planétaire simple, qui est solidaire du pignon principal de l'engrenage planétaire double et qui est connecté de manière solidaire à une roue intermédiaire, un arbre d'entrée (15) et un embrayage (C3) permettant à l'arbre d'entrée (15) d'être en prise avec la couronne de l'engrenage planétaire simple (10), ou de se désaccoupler de celui-ci, au moyen d'un organe de connexion (16). L'organe de connexion (16) est connecté à la couronne de l'engrenage planétaire double (11) au moyen d'un embrayage (CO), d'un frein (B1) d'embrayage ou de débrayage de l'engrenage planétaire et d'un frein (B2) d'embrayage ou de débrayage de la couronne de l'engrenage planétaire double (11). Un engrenage de sortie (13) est agencé sur la roue intermédiaire.
