Patent ID: 8226512

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 planetary 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; a motor/generator operatively connected with said first external gear of said second external gear set; a first torque-transmitting device selectively connecting said first member of said first planetary gear set with a stationary member; a second torque-transmitting device selectively connecting said first external gear of said third external gear set with said input member; a third torque-transmitting device selectively connecting said third member of said second planetary gear set with said third member of said third planetary gear set; a fourth torque-transmitting device selectively connecting said first external gear of said second external gear set with said first external gear of said third external gear set; a fifth torque-transmitting device selectively connecting said second external gear of said first external gear set with said third member of said third planetary gear set; and 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.
