1. speed changer comprises:

  • Input link;

    Output link;

    First, second, third and the fourth line star gear train that respectively have first, second and the 3rd member;

    First interconnecting component, described first interconnecting component interconnects described first member of described first planetary gear set and described first member of described second planetary gear set continuously;

    Second interconnecting component, described second interconnecting component interconnects described second member of described first planetary gear set and described second member of described the third line star gear train continuously;

    The 3rd interconnecting component, described the 3rd interconnecting component interconnects described first member of described second planetary gear set and described first member of described the third line star gear train continuously;

    The 4th interconnecting component, described the 4th interconnecting component interconnects described the 3rd member of described second planetary gear set and described second member of described the third line star gear train continuously;

    The 5th interconnecting component, described the 5th interconnecting component interconnects described the 3rd member of described the third line star gear train and described the 3rd member of described fourth line star gear train continuously;

    WithSix torque transmitters, described torque transmitter optionally engage with one in described first, second and the 3rd member with described first, second, third member and fixed component in another interconnection at least, andWherein, described torque transmitter optionally engages with at least two combining form, to set up at least nine forward velocity ratios and at least one reverse speed ratio between described input link and described output link.
