Abstract:
1. A two-mode compound split hybrid electro-mechanical transmission, comprising: first and second motor/generators; first, second and third planetary gear sets, each planetary gear set utilizing first, second and third gear members; said first and second motor/generators being coaxially aligned with each other and with said three planetary gear sets; at least one of said gear members in said first or second planetary gear set being connected to said first motor/generator; at least one of said gear members in said third planetary gear set being connected to said second motor/generator; a first torque-transmitting mechanism selectively connecting one of said gear members of said third planetary gear set with ground; a second torque-transmitting mechanism selectively connecting one of said gear members associated with each of said first, second and third planetary gear sets to each other and to said output member; a third torque-transmitting mechanism selectively connecting one of said gear members of said second planetary gear set with ground; a fourth torque-transmitting mechanism selectively connecting one of said gear members with another of said gear members; a fifth torque-transmitting mechanism selectively connecting one of said gear members of said second planetary gear set with one of said gear members of said third planetary gear set; a first interconnecting member continuously connecting one of said gear members of said first planetary gear set with one of said gear members of said second planetary gear set; and a second interconnecting member continuously connecting another one of said gear members of said first planetary gear set with another one of said gear members of said second planetary gear set.
