1. speed changer comprises:

  • Input element;

    Output element;

    Stationary element;

    Planetary gear set, it comprises the first central gear element, the first ring gear element and the first planet carrier element;

    It is characterized in that said speed changer also comprises;

    The compound gear group, it comprises the second central gear element, the 3rd central gear element, the second ring gear element, the 3rd ring gear element, the second planet carrier element, the second planetary pinion element that rotatably is connected with the second planet carrier element and meshes the first planetary pinion element of said second central gear element and the said second ring gear element and rotatably be connected and mesh said the 3rd central gear element, the said first planetary pinion element and said the 3rd ring gear element with the second planet carrier element;

    Said first central gear element continuous running ground is connected with said input element;

    Said the 3rd ring gear element continuous running ground is connected with said output element;

    AndFirst, second, third, fourth, the 5th, the 6th and the 7th torque transmitter;

    Wherein said first torque transmitter is configured to optionally make said first ring gear element and the coupling of said stationary element;

    Said second torque transmitter is configured to optionally make said first planet carrier element and the coupling of said stationary element;

    Said the 3rd torque transmitter is configured to optionally be coupled the said first planet carrier element and the said second central gear element so that consistent the rotation;

    Said the 4th torque transmitter is configured to optionally be coupled the said first ring gear element and the said second ring gear element so that consistent the rotation;

    Said the 5th torque transmitter is configured to optionally be coupled the said first planet carrier element and said the 3rd central gear element so that consistent the rotation;

    Said the 6th torque transmitter is configured to optionally make said input element to be coupled so that consistent the rotation with said first central gear element and said the 3rd central gear element;

    And said the 7th torque transmitter be configured to optionally make said input element and the said first central gear element with said second planet carrier element coupling so that consistent the rotation, thereby at least seven forward speed ratios are provided.
