Abstract:
1. A multi-speed transmission of a planetary gearset design for an automatic transmission of a motor vehicle, the transmission having: an input shaft (AN) and an output shaft (AB), first, second, third and fourth planetary gearsets (RS at least first, second, third, fourth, fifth, sixth, seventh and eighth rotatable shafts ( first, second, third, fourth and fifth shifting elements (A, B, C, D, E) whose selective engagement provides different speed rotation ratios between the input shaft (AN) and the output shaft (AB) so that eight forward gear ratios, and at least one reverse gear ratio may be realized, and whereby: a carrier (ST a carrier (ST a sun gear (S a ring gear (HO a ring gear (HO a carrier (ST a sun gear (SO a carrier (ST the first shifting element (A) is located between the third shaft ( the second shifting element (B) is located between the fourth shaft ( the third shifting element (C) is located in a power flow direction between the fifth shaft ( the fourth shifting element (D) is located in the power flow direction either between the eighth shaft ( the fifth shifting element (E) is located in the power flow direction either between the seventh shaft (
