1. an electric gear shift(ing), comprising:

  • In order to accept the input block of engine power;

    Output block;

    First motor/generator and the second motor/generator;

    First, second, and third planetary gear set, they respectively have three parts;

    ring gear, sun gear and planet carrier;

    Described input block constantly or is optionally connected with parts of described first, second or third planet gear train, and described output block is connected with another parts of described first, second or third planet gear train constantly;

    Constantly by the first interconnecting member that the first component of the first component of described first planet gear train and described second planetary gear set couples together;

    Constantly by the second interconnecting member that the second component of the second component of described first planet gear train and described second planetary gear set couples together;

    Constantly by the second component of the first component of described third planet gear train and described second planetary gear set or the 3rd parts, or the 3rd interconnecting member coupled together with fixed component;

    Described first motor/generator is connected with parts of described first planet gear train or the second planetary gear set constantly or optionally;

    Described second motor/generator is connected with parts of described second planetary gear set or third planet gear train constantly, and these parts are different from the described parts be connected with described first motor/generator;

    Optionally by the first torque transmitter that parts of described input block and described first planet gear train or the second planetary gear set couple together;

    Optionally by the second torque transmitter that parts of described input block and described first, second or third planet gear train couple together, these parts are different from the parts be connected on described first torque transmitter;

    Optionally by parts of described first, second or third planet gear train and described fixed component or the 3rd torque transmitter that couples together with described input block;

    Be connected with the described first or second motor/generator is parallel, for optionally rotating to it the 4th torque transmitter braked;

    Be connected with another motor/generator in the described first or second motor/generator is parallel, for optionally rotating to it the 5th torque transmitter braked;

    Wherein, described first, second, third, fourth and fifth torque transmitter can individually or two or three engage in combination, thus provide a kind of with the electric gear shift(ing) of continuously variable speed than scope and four fixing forward velocity ratios.
