Patent ID: 8167753

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; 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; and a motor/generator operatively connected with said first external gear of said second external gear set; and five torque-transmitting devices for selectively interconnecting said members of said planetary gear sets or said first and second external gears with each other, with a stationary member, with said input member, or with other members of said planetary 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.
