Patent ID: 8360923

Claim:
A multi-speed transmission comprising: an input member; an output member; a stationary member; a first compound planetary gear set and a second simple planetary gear set; wherein the input member, the output member and the planetary gear sets are arranged coaxially with one another to define a first axis of rotation; a first and a second layshaft arranged coaxially with one another to define a second axis of rotation; a first set of intermeshing gears arranged to transfer torque from the input member to the first layshaft; a second set of intermeshing gears arranged to transfer torque from the second layshaft to the second planetary gear set; and seven torque-transmitting mechanisms each selectively engagable to connect a respective member of the planetary gear sets or a respective one of the layshafts to the stationary member or for common rotation with the input member, with another respective member of the planetary gear sets or with another respective one of the layshafts; the seven torque-transmitting mechanisms being engagable in different combinations to establish multiple forward speed ratios and a reverse speed ratio between the input member and the output member.
