Patent ID: 8360924

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 planetary gear set has a first, a second, a third, a fourth, and a fifth member; wherein the second 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 first compound planetary gear set is continuously connected for common rotation with the input member; wherein the first member of the second compound planetary gear set is continuously connected for common rotation with the output member; wherein the second member of the second compound planetary gear set is continuously grounded to the stationary member; wherein none of the members of the first planetary gear set are continuously connected for common rotation with any of the members of the second planetary gear set; and seven torque-transmitting mechanisms selectively engagable to interconnect a respective one of the members of the first compound planetary gear set with the input member, the stationary member or a respective member of the second compound planetary gear set, the seven torque-transmitting mechanisms being engagable in different combinations to establish up to ten forward speed ratios and a reverse speed ratio between the input member and the output member.
