Patent ID: 8083633

Claim:
A multi-speed hybrid transmission comprising: an input member; an output member; first, second and third planetary gear sets each having first, second and third members, said gear sets being positioned along first and second axes; an interconnecting member continuously connecting said second member of said second planetary gear set with said second member of said third planetary gear set; first, second and third external gear sets positioned for transferring torque between said first and second axes, said first, second and third external gear sets each including first and second intermeshed external gears; a motor/generator operatively connected with said first external gear of said second external gear set; wherein said third member of said first planetary gear set is continuously connected with said first external gear of said second external gear set for rotation at the same speed; wherein said first member of said second planetary gear set is continuously connected with said second external gear of said second external gear set for rotation at the same speed; and five torque-transmitting devices; wherein each of said five torque-transmitting devices selectively interconnects a respective one of said members of said planetary gear sets or a respective one of said first and second external gears of said three external gear with a stationary member, with said input member, with another respective one of said members of said planetary gear sets or with another respective one of said first and second external gears of said three external gear sets, said five torque-transmitting devices being engaged in combinations of three to establish at least eight forward speed ratios and at least one reverse speed ratio between said input member and said output member.
