Abstract:
A hybrid transmission is configured to transfer mechanical power to an output member and includes an input member, an output member, and a transmission case circumscribing first and second differential gear sets, each differential gear set including a plurality of meshingly engaged rotatable elements. The first differential gear set is configured with four nodes for transferring mechanical power, and the second differential gear set is configured with three nodes for transferring mechanical power. Two of the four nodes of the first differential gear set are continuously interconnected to two of the three nodes of the second differential gear set. A first torque transfer clutch is configured to selectively connect the input member to an internal combustion engine. First and second brake devices are configured to selectively interconnect elements of the first and second differential gear sets, the transmission case, the input member, and the output member.
