Abstract

La transmission pour véhicule présente un arbre d'entrée (5) comportant un arbre d'entrée principal (10) et un arbre d'entrée secondaire (11) coaxial en périphérie externe. Un convertisseur de couple (4) est relié à une première extrémité (10a) de l'arbre d'entrée principal. Un train épicycloïdal (21) permet de coupler l’arbre d’entrée principal à une première extrémité (11a) de l’arbre d’entrée secondaire et permet de réduire la vitesse de rotation de l’arbre d’entrée principal et de fournir la puissance à l’arbre d’entrée secondaire. Un embrayage (51) est disposé aux deuxièmes extrémités (10b, 11b) de ces arbres et permet de réaliser ou de bloquer sélectivement la transmission de la puissance de l’arbre d’entrée principal à l'arbre d'entrée secondaire. Les pignons de 4ème et 5ème vitesse (71, 72) et le synchroniseur (74) sont montés sur l'arbre d’entrée secondaire entre le convertisseur de couple et l’embrayage dans la direction axiale de l'arbre d’entrée secondaire. Fig . 2The vehicle transmission has an input shaft (5) comprising a main input shaft (10) and a secondary input shaft (11) coaxial at the outer periphery. A torque converter (4) is connected to a first end (10a) of the main input shaft. A planetary gear train (21) makes it possible to couple the main input shaft to a first end (11a) of the secondary input shaft and makes it possible to reduce the rotational speed of the main input shaft and to provide power to the secondary input shaft. A clutch (51) is arranged at the second ends (10b, 11b) of these shafts and makes it possible to carry out or selectively block the transmission of power from the main input shaft to the secondary input shaft. The 4th and 5th gears (71, 72) and the synchronizer (74) are mounted on the secondary input shaft between the torque converter and the clutch in the axial direction of the secondary input shaft.
