Patent ID: 7179191

Claim:
A multi-stage automatic transmission comprising: an input drive shaft (AN), and an output drive shaft (AB); only first, second, third, fourth and fifth shifting elements (A to E) and selective engagement of desired ones of the first, the second, the third, the fourth and the fifth shifting elements (A to E) achieves at least six forward gears and at least one reverse gear; at least a first, a second and a third planetary gear sets (RS 1 , RS 2 , RS 3 ) aligned coaxially to one another with the second planetary gear set (RS 2 ) positioned between the first and the third planetary gear sets (RS 1 , RS 3 ); a sun gear (SO 3 ) of the third planetary gear set (RS 3 ) is connectable by the first shifting element (A) to a transmission housing (GG) of the multi-stage automatic transmission, a sun gear (SO 2 ) of the second planetary gear set (RS 2 ) is connected with the input drive shaft (AN), and the input drive shaft (AN) is connectable by at least one of the second shifting element (B) with a sun gear (SO 1 ) of the first planetary gear set (RS 1 ) and the fifth shifting element (E) with a spider (ST 1 ) of the first planetary gear set (RS 1 ); alternatively, a sun gear (SO 1 ) of the first planetary gear set (RS 1 ) is affixed, by one of the third shifting element (C) and the spider (ST 1 ) of the first planetary gear set (RS 1 ) via the fourth shifting element (D), to the transmission housing (GG); the output drive shaft (AB) is connected with an internal gear (HO 1 ) of the first planetary gear set (RS 1 ) and with one of the spiders (ST 2 , ST 3 ) of the second and the third planetary gear set (RS 2 , RS 3 ); and wherein the output shaft penetrates, in an axial direction, at least one of the first planetary gear set (RS 1 ) and the second planetary gear set (RS 2 ).
