Multi-stage transmission for vehicles

A multi-stage transmission for a vehicle, the multi-stage transmission comprising:

• a first planetary gear set, a second planetary gear set, a third planetary gear set, and a fourth planetary gear set, each includes three rotating elements;
• six shifting elements configured to selectively connect rotation shafts thereto;
• and
• eight rotation shafts connected to the rotating elements of the first, the second, the third, and the fourth planetary gear sets,
• wherein a first rotation shaft is an input shaft,
• wherein a second rotation shaft is fixedly connected to a first rotating element of the first planetary gear set, a first rotating element of the second planetary gear set, and a second rotating element of the third planetary gear set,
• wherein a third rotation shaft is fixedly connected to a second rotating element of the first planetary gear set, a third rotating element of the third planetary gear set, and a third rotating element of the fourth planetary gear set,
• wherein a fourth rotation shaft is fixedly connected to a third rotating element of the first planetary gear set,
• wherein a fifth rotation shaft is fixedly connected to a second rotating element of the second planetary gear set,
• wherein a sixth rotation shaft is fixedly connected to a third rotating element of the second planetary gear set and a first rotating element of the third planetary gear set,
• wherein a seventh rotation shaft is fixedly connected to a first rotating element of the fourth planetary gear set, and
• wherein an eighth rotation shaft is an output shaft fixedly connected to a second rotating element of the fourth planetary gear set.
