Multi-speed gearbox

A multi-speed automatic gearbox of a planetary design for a motor vehicle, the gearbox comprising:

• an input shaft (AN),
• an output shaft (AB),
• first, second, third and fourth planetary gearsets (RS1, RS2, RS3, RS4), at least first, second, third, fourth, fifth, sixth, seventh and eighth rotatable shafts (1, 2, 3, 4, 5, 6, 7, 8), and first, second, third, fourth and fifth shifting elements (A, B, C, D, E), whose selective engagement determines a variety different gear ratios between the input shaft (AN) and the output shaft (AB) such that eight forward gears and at least one reverse gear can be implemented;
• a carrier (ST3) of the third planetary gearset (RS3) and the output shaft (AB) are coupled one another and comprise the second shaft (2);
• a sun gear (SO1) of the first planetary gearset (RS1) and a sun gear (SO4) of the fourth planetary gearset (RS4) are coupled one another and comprise the third shaft (3);
• a ring gear (HO1) of the first planetary gearset (RS1) is integral with the fourth shaft (4);
• a carrier (ST1) of the first planetary gearset (RS1) and a ring gear (HO3) of the third planetary set (RS3) are coupled one another and comprise the sixth shaft (6);
• a sun gear (SO2) of the second planetary gearset (RS2) and a ring gear (HO4) of the fourth planetary gearset (RS4) are coupled one another and comprise the seventh shaft (7);
• a carrier (ST2) of the second planetary gearset (RS2) is integral with the eighth shaft (8);
• a ring gear (HO2) of the second planetary gearset (RS2) and the input shaft (AN) are coupled one another and comprise the first shaft (1);
• a sun gear (SO3) of the third planetary gearset (RS3) and a carrier (ST4) of the fourth planetary gearset (RS4) are coupled one another and comprise the fifth shaft (5);
• the first shifting element (A) being between the third shaft (3) and a gearbox housing (GG);
• the second shifting element (B) being located between the fourth shaft (4) and the gearbox housing (GG);
• the third shifting element (C) being located, in a direction of power flow, between the first shaft (1) and the fifth shaft (5);
• the fourth shifting element (D) being located, in the direction of power flow, between the eighth shaft (8) and the second shaft (2);
• and
• the fifth shifting element (E) being located, in the direction of power flow, between the fifth shaft (5) and the eighth shaft (8).
