FAMILY OF MULTI-SPEED PLANETARY TRANSMISSIONS EACH HAVING TWO INPUT CLUTCHES AND THREE PLANETARY GEARSETS

摘要

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.
