Multi-speed transmission

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

• an input shaft (AN);
• an output shaft (AB);
• first, second, third and fourth planetary gearset (RS1, R52, R53, R54);
• 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 generates a plurality of reduction 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 sun gear (SO1) of the first planetary gearset (RS1) and a sun gear (SO4) of the fourth planetary gearset (R54) are connected with one another and form the third shaft (3);
• a ring gear (HO1) of the first planetary gearset (RS1) forms the fourth shaft (4);
• a carrier (ST1) of the first planetary gearset (RS1) and a ring gear (HO3) of the third planetary gearset (RS3) are connected with one another and form the sixth shaft (6);
• a carrier (ST2) of the second planetary gearset (RS2) forms the eighth shaft (8);
• a ring gear (HO4) of the fourth planetary gearset (RS4) and the input shaft (AN) are connected with one another and form the first shaft (1);
• a ring gear (HO2) of the second planetary gearset (RS2) and a carrier (ST3) of the third planetary gearset (RS3) and the output shaft (AB) are connected with one another and form the second shaft (2);
• a sun gear (SO3) of the third planetary gearset (RS3) forms the fifth shaft (5);
• a sun gear (SO2) of the second planetary gearset (RS2) and a carrier (ST4) of the fourth planetary gearset (RS4) are connected with one another and form the seventh shaft (7);
• the first shifting element (A) is located between the third shaft (3) and a housing (GG) of the transmission;
• the second shifting element (B) is arranged between the fourth shaft (4) and the housing (GG) of the transmission;
• the third shifting element (C) is arranged, in a direction of power flow, between the first shaft (1) and the fifth shaft (5);
• the fourth shifting element (D) is arranged, in a direction of power flow, between the sixth shaft (6) and the eighth shaft (8);
• and
• the fifth shifting element (E) is arranged, in a direction of power flow, between the fifth shaft (5) and the seventh shaft (7).
