Abrégé
(EN)
The family of transmissions (10) has a plurality of members that can be utilized in powertrains to provide at least six forward speed ratios and one reverse speed ratio. The transmission family members include three planetary gear sets (20, 30, 40) having up to seven torque-transmitting mechanisms and four interconnecting members. The powertrain includes an engine (12) that is selectively or continuously connectable to at least one of the planetary gear members (20, 30, 40) and an output shaft (19) that is continuously connected with another one of the planetary gear members (20, 30, 40). The torque-transmitting mechanisms (50, 52, 54, 55, 57) provide interconnections between various gear members, the input shaft (17) and the transmission housing (60) and are operated in combinations of two to establish at least six forward speed ratios and at least one reverse speed ratio.

Les boîtes de vitesse de cette famille comptent une pluralité d'éléments dont l'utilisation dans des chaînes cinématiques donne au moins six rapports AV et un rapport AR. Ces éléments sont constitués de trois trains planétaires possédant jusqu'à sept mécanismes de transmission du couple et quatre éléments d'interconnexion. La chaîne cinématique comprend un moteur raccordable soit sélectivement, soit en continu à au moins l'un des éléments de train planétaire et un arbre de sortie raccordé en permanence à un autre des éléments de train planétaire. Les mécanismes de transmission du couple assurent la liaison entre divers éléments de pignon, l'arbre d'entrée et le carter de boîte de vitesse, et se combinent par deux pour donner au moins six rapports AV et au moins un rapport AR.
