1. , with the attachable hybrid electromechanical transmission of power source, comprising:

  • Input link, described input link is connected with described power source;

    Output link;

    Planetary gear set, described planetary gear set has first, second and the 3rd component;

    First motor/generator and the second motor/generator;

    Battery, is describedly connected to described motor/generator battery-operatedly, to receive power and to described motor/generator transmitting power from described motor/generator;

    Wherein said input link is connected with described first component operation ground;

    Wherein said first motor/generator operatively connect with described second component in case together with rotate;

    Wherein said second motor/generator and described output link operatively directly connect in case together with rotate;

    First torque-transmitting mechanisms, described first torque-transmitting mechanisms can engage to be connected with described 3rd component by described second motor/generator in case together with rotate;

    AndWherein when described first torque-transmitting mechanisms is not engaged, described battery and the second motor/generator provide pure electronic mode of operation to provide power to described output link;

    Thus described power source, planetary gear set and the first motor/generator disconnect with described output link during pure electronic mode of operation, to prevent parasitic drag;

    Wherein said battery, described second motor/generator and described power source provide input flow deviding type mode of operation, in described input flow deviding type mode of operation, described second motor/generator and described power source provide power and described first torque-transmitting mechanisms is engaged to described output link;

    Wherein said first torque-transmitting mechanisms is the overrunning clutch being automatically in the overspeed condition of disengagement during pure electronic mode of operation;

    Wherein speed changer does not have torque-transmitting mechanisms during pure electronic mode of operation.
