Multispeed transmission

A multispeed automatic transmission, of a planetary gear design, for a motor vehicle, the transmission comprising:

• a drive shaft (1) and an output shaft (2) located within a housing (G);
• first, second and third planetary gear sets (P1, P2, P3);
• at least additional third, fourth, fifth, sixth and seventh rotating shafts (3, 4, 5, 6, 7);
• a plurality of shift elements (03, 04, 05, 15, 57, 67), including first, second and third brakes (03, 04, 05) and first, second and third clutches (15, 57, 67), whose selective engagement results in a plurality transmission gear ratios between the drive shaft (1) and the output shaft (2) and achieves at least eight forward gears and at least one reverse gear;
• a sun gear of the second planetary gear set (P2) being fixed the drive shaft (1) and being detachably coupled, via the first clutch (15), with the fifth shaft (5);
• a carrier of the first planetary gear set (P1) being fixed to the fifth shaft (5) and being detachably coupled, via the third brake (05), to the housing (0), and being detachably coupled, via the second clutch (57), to the seventh shaft (7);
• a carrier of the second planetary gear set (P2) being fixed to the seventh shaft (7) and being detachably coupled, via the third clutch (67), to the sixth shaft (6);
• a sun gear of the first planetary gear set (P1) and a ring gear of the third planetary gear set (P3) being fixed to the sixth shaft (6);
• a ring gear of the second planetary gear set (P2) and a carrier of the third planetary gear set (P3) being fixed to the first shaft (3) and being detachably coupled, via the first brake (03), with the housing (G);
• a sun gear of the third planetary gear set (P3) being fixed to the fourth shaft (4) and being detachably coupled, via the second brake (04), with the housing (G);
• and
• a ring gear of the first planetary gear set (P1) being fixed to the output shaft (2).
