摘要:
A family of transmissions having a plurality of family members each having three planetary gearsets and six torque-transmitting mechanisms. The planetary gearsets and the torque-transmitting mechanisms are interconnected such that at least seven forward speed ratios and one reverse speed ratio can be established within the three planetary gearsets and transmitted between an input shaft and an output shaft, by selectively engaging the torque transmitting mechanisms in combinations of four.
摘要:
A family of power transmissions includes three planetary gearsets, which each have a member interconnected with one of the other planetary gearsets, and two of the planetary gearsets have a second member continuously interconnected. Each family member includes six torque-transmitting mechanisms which are engaged in combinations of two to establish at least seven forward speed ratios and one reverse speed ratio within the planetary gear arrangement between the transmission input shaft and the transmission output shaft.

A family of power transmissions having first, second, and third planetary gearsets and six torque-transmitting mechanisms. The first planetary gearset is continuously interconnected with a member of the second planetary gearset and a member of the third planetary gearset. The second planetary gearset is continuously interconnected with a member of the third planetary gearset. The six torque-transmitting mechanisms are selectively engaged in combinations of two to establish at least seven forward speed ratios and one reverse speed ratio within the planetary gearsets.
摘要:
The family of transmissions has a plurality of members that can be utilized in powertrains to provide at least seven forward speed ratios and at least one reverse speed ratio. The transmission family members include three planetary gear sets having six torque-transmitting mechanisms and two fixed interconnections. Also, one planetary gear member is continuously connected with the transmission housing. The powertrain includes an engine and torque converter that is continuously connected to at least one of the planetary gear members and an output member that is continuously connected with at least one of the planetary gear members. The six torque-transmitting mechanisms provide interconnections between various gear members, the fixed interconnections, the input shaft, the output shaft, and the transmission housing, and are operated in combinations of two to establish at least seven forward speed ratios and one reverse speed ratio.
摘要:
A family of power transmissions have three planetary gearsets each of which have first, second, and third members. A pair of fixed interconnecting members establish continuous connections between a member of the first planetary gearset and a member of the second planetary gearset, and between another member of the second planetary gearset and a member of the third planetary gearset, respectively. Each of the transmission family members has an output shaft, which is continuously connected with at least one member of one of the planetary gearsets and an input shaft, which is selectively connectible with at least two members of the planetary gearsets through respective first and second torque-transmitting mechanisms. Four other torque-transmitting mechanisms are provided to establish various interconnections between members of the planetary gearsets and/or members of the planetary gearsets and the transmission housing. The six torque-transmitting mechanisms are selectively engageable in combinations of four to establish at least seven forward speed ratios and one reverse speed ratio between the input shaft and the output shaft through the planetary transmission.

A family of power transmissions has a plurality of family members each of which have three planetary gearsets, each having three members, and six torque transmitting mechanisms. An output shaft is continuously interconnected with at least one planetary member. An input shaft is selectively interconnected with respective planetary members through at least two of the torque transmitting mechanisms. One member of the second planetary gearset and one member of the third planetary gearset are continuously interconnected, and another member of the third planetary gearset is continuously interconnected with a transmission housing. The remaining torque transmitting mechanisms provide selective interconnections between two planetary members or between a planetary member and the housing, the input shaft, and the output shaft. The torque transmitting mechanisms are selectively engaged in combinations of four to establish at least seven forward speeds and one reverse speed.
