Patent ID: 8540600

Claim:
A multi-speed transmission comprising: an input member; an output member; a stationary member; a first and a second compound planetary gear set; wherein the first compound planetary gear set has a first, a second, a third, a fourth, and a fifth member; wherein the second compound planetary gear set has a first, a second, a third, and a fourth member; wherein the members of the planetary gear sets are sun gear members, ring gear members and carrier members; wherein the first member of the second compound planetary gear set is continuously connected for common rotation with the output member; an interconnecting member continuously connecting the first member of the first compound planetary gear set for common rotation with the second member of the second compound planetary gear set; and only seven torque-transmitting mechanisms, including three brakes and four rotating clutches; wherein each of the seven torque-transmitting mechanisms is selectively engagable to interconnect a respective one of the members of the first and the second compound planetary gear sets with the input member, the stationary member or a respective one of the members of the second compound planetary gear set, the seven torque-transmitting mechanisms being engagable in different combinations to establish up to fourteen forward speed ratios and a reverse speed ratio between the input member and the output member.
