1. speed changer comprises:

  • Input link;

    Output link;

    First planetary gear set, it has first, second and the 3rd member;

    Second planetary gear set, it has first, second and the 3rd member;

    Stacked planetary gear set arranges that it has first member, second member, the 3rd member, the 4th member and the 5th member;

    The first interconnected member, its second member with first member of said first planetary gear set and said second planetary gear set is interconnected constantly;

    The second interconnected member, its 3rd member with second member of said first planetary gear set and said second planetary gear set is interconnected constantly;

    The 3rd interconnected member, its 4th member that the 3rd member and the said stacked planetary gear set of said first planetary gear set are arranged is interconnected constantly;

    The 4th interconnected member, its 4th member that second member and the said stacked planetary gear set of said stacked planetary gear set layout are arranged is interconnected constantly;

    AndAt least six torque-transmitting mechanisms;

    It can engage selectively;

    With the first, second, third, fourth and the 5th member that said stacked planetary gear set is arranged and said first and second planetary gear set first, second with the 3rd member at least one with first, second and the 3rd member and fixed component of the first, second, third, fourth and the 5th member of said stacked planetary gear set layout and said first and second planetary gear set in another is interconnected at least, andWherein said at least six torque-transmitting mechanisms can be selectively engage with the combination of three torque-transmitting mechanisms at least, between said input link and said output link, to set up at least eight forward gear speed ratios and at least one speed ratio that reverses gear.
