发明名称 Multi-speed transmission
摘要 A transmission is provided having an input member, an output member, four planetary gear sets each having a first, a second, and a third members, a plurality of coupling members and a plurality of torque transmitting devices. Each of the planetary gear sets includes first, second and third members. The torque transmitting devices are each selectively engageable to interconnect at least one of the first, second, and third members of the planetary gear sets with at least one other of the first members, second members, third members of the planetary gear sets, and a stationary member. The torque transmitting devices are selectively engageable in combinations of at least two to establish at least eight forward speed ratios and at least one reverse speed ratio between the input member and the output member.
