Family of multi-speed transmissions with interconnected planetary gearsets and a plurality of input clutches

   
   

A family of power transmissions wherein each family member includes three planetary gearsets with three interconnecting members providing continuous interconnections between members of the planetary gearsets. The family members further include six selectively engageable torque-transmitting mechanisms, which are engaged in combinations of two to establish seven forward speed ratios and one reverse speed ratio between an input shaft and an output shaft of a transmission.

Una famiglia delle trasmissioni di alimentazione in cui ogni membro della famiglia include tre gearsets planetari con tre membri collegati che forniscono le interconnessioni continue fra i membri dei gearsets planetari. I membri della famiglia ulteriori includono selettivamente sei meccanismi coppia di torsione-trasmettenti engageable, che sono agganciati nelle combinazioni di due stabilire sette rapporti di andata di velocità ed un rapporto d'inversione di velocità fra un albero dell'input e un braccio di abbattimento di una trasmissione.
