    摘要： The electrically variable transmission family of the present invention provides low-content, low-cost electrically variable transmission mechanisms including first and second differential gear sets, a battery, two electric machines serving interchangeably as motors or generators, and four or five selectable torque-transfer devices. The selectable torque transfer devices are engaged singly or in combinations of two to yield an EVT with a continuously variable range of speeds (including reverse) and three mechanically fixed forward speed ratios. The torque transfer devices and the first and second motor/generators are operable to provide five operating modes in the electrically variable transmission, including battery reverse mode, EVT reverse mode, reverse and forward launch modes, continuously variable transmission range mode, and fixed ratio mode.

    摘要： 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.
