CA 2648268

A dual clutch transmission for use in a motor vehicle having an engine (12) and a driveline includes an output shaft (34) adapted for connection to the driveline and a planetary gearset (33) in constant driving engagement with the output shaft. An input shaft (20) is driven by the engine. A first constant mesh gearset (74) is in selective driving communication with a first member of the planetary gearset. A second constant mesh gearset (76) is in selective driving communication with a second member of the planetary gearset. A first clutch (14) is operable for establishing a releasable drive connection between the input shaft and first constant mesh gearset. A second clutch (16) is operable for establishing a releasable drive connection between the input shaft and the second constant mesh gearset. A motor (200) is selectively drivingly coupled to a third member of the planetary gearset.

Boîte de vitesses à double embrayage s'utilisant dans un véhicule à moteur et une transmission, qui comprend un arbre de sortie conçu pour assurer la liaison avec la transmission et un train planétaire en prise constante avec ledit arbre de sortie. Un arbre d'entrée est entraîné par le moteur. Un premier train de pignons en prise constante est en communication motrice sélective avec un premier élément du train planétaire. Un second train de pignons en prise constante est en communication motrice sélective avec un second élément du train planétaire. Un premier embrayage intervient pour établir une liaison motrice débrayable entre l'arbre d'entrée et le premier train de pignons en prise constante. Un second embrayage intervient pour établir une liaison motrice débrayable entre l'arbre d'entrée et le second jeu de pignons en prise constante. Un moteur est couplé sélectivement de façon motrice avec un troisième élément du train planétaire.
