SIX SPEED PLANETARY TRANSMISSION MECHANISMS WITH THREE INTERCONNECTED GEARSETS |
摘要 |
A family of transmissions has a plurality of members each of which includes three planetary gearsets, five torque-transmitting mechanisms, an input shaft, and an output shaft. The torque-transmitting mechanisms are selectively engageable in combinations of three to establish at least six forward speed ratios and one reverse speed ratio between the input shaft and the output shaft of each family member. Each family member has two continuous interconnecting members, one of which interconnects a member the first planetary gearset with a member of the second planetary gearset, and the second of which connects another member of the second planetary gearset with a member of the third planetary gearset. The five torque-transmitting mechanisms complete the connections between the planetary gear members and/or the transmission housing which are necessary to provide the six forward speed ratios and one reverse speed ratio.
