Family of multi-speed planetary transmissions each having two input clutches and three planetary gearsets

   
   

A family of transmissions employing three planetary gearsets and five torque-transmitting mechanisms provides at least six forward speed ratios and one reverse speed ratio when the torque-transmitting mechanisms are engaged in combinations of three. Three interconnecting members continuously interconnect six members of the planetary gear sets. The output shaft is continuously interconnected with at least one member of the planetary gear sets, and the input shaft is not continuously interconnected with any member of the planetary gear sets. The torque-transmitting mechanisms consist of both selectively engageable rotating type torque-transmitting mechanisms and selectively engageable stationary type torque-transmitting mechanisms.

Una familia de transmisiones que emplea tres gearsets planetarios y cinco mecanismos esfuerzo de torsio'n-que transmiten proporciona por lo menos seis cocientes delanteros de la velocidad y un cociente reverso de la velocidad cuando los mecanismos esfuerzo de torsio'n-que transmiten se contratan a combinaciones de tres. Tres miembros de interconexión de la interconexión seises de los miembros del engranaje planetario fijan continuamente. El eje de salida se interconecta continuamente con por lo menos un miembro de los sistemas planetarios del engranaje, y el eje de la entrada no se interconecta continuamente con ningún miembro de los sistemas planetarios del engranaje. Los mecanismos esfuerzo de torsio'n-que transmiten consisten en selectivamente el tipo que rota engageable mecanismos esfuerzo de torsio'n-que transmiten y selectivamente el tipo inmóvil engageable mecanismos esfuerzo de torsio'n-que transmiten.
