1. electrically variable transmission, it comprises:

  • Be used for from the input block of motor received power;

    Output block;

    First motor/generator and second motor/generator;

    First differential gear set, second differential gear set and the 3rd differential gear set, it respectively has first parts, second parts and the 3rd parts;

    Described input block is connected with at least one parts of described gear train selectively, and described output block is connected with another parts of described gear train constantly;

    First interconnecting member, it couples together described first parts of described first gear train and described first parts of described second gear train constantly;

    Second interconnecting member, it couples together constantly with described second parts of described second parts of described first gear train and described second gear train or with described first parts of described the 3rd gear train;

    Described first motor/generator is connected constantly with the parts of described first gear train;

    Described second motor/generator is connected constantly with the parts of the parts of described first gear train, described second gear train or the parts of described the 3rd gear train, perhaps is connected selectively with the parts of described second gear train by dog-clutch;

    First torque transmitter, it couples together the parts of described first gear train or the parts and the described input block of described second gear train selectively;

    Second torque transmitter, it couples together the parts of described first gear train and the parts of described the 3rd gear train selectively;

    The 3rd torque transmitter, it couples together selectively with the parts of the parts of described the 3rd gear train and described first gear train or with the parts of described second gear train;

    The 4th torque transmitter, the parts of its parts with described first gear train, second gear train or the parts and the fixed component of the 3rd gear train couple together selectively;

    The 5th torque transmitter, it is connected with a motor/generator in described second motor/generator is parallel with described first motor/generator, is used for preventing selectively its rotation;

    AndWherein, described first torque transmitter, described second torque transmitter, described the 3rd torque transmitter, described the 4th torque transmitter and described the 5th torque transmitter can engage, and have the electrically variable transmission of continuously variable speed than scope and at least four fixing forward velocity ratios to provide.
