Patent ID: 7470208

Claim:
A multistep automatic transmission comprising; a drive shaft (AN) and an output shaft (AB); at least first, second and third planetary gearsets (RS 1 , RS 2 , RS 3 ) and each of the first planetary gearset (RS 1 ), the second planetary gearset (RS 2 ), and the third planetary gearset (RS 3 ) comprising a sun gear, a carrier and a ring gear; at least first, second, third, fourth and fifth shifting components (A, B, C, D, E); the first planetary gearset (RS 1 ), the second planetary gearset (RS 2 ) and the third planetary gearset (RS 3 ) being aligned co-axially with one another; the second planetary gearset (RS 2 ) and the third planetary gearset (RS 3 ) are axially adjacent one another; the sun gear (SO 3 ) of the third planetary gearset (RS 3 ) being engagable, via the first shifting component (A), with a transmission housing (GG) of the multistep automatic transmission; the drive shaft (AN) being connected to the sun gear (SO 2 ) of the second planetary gearset (RS 2 ); the drive shaft (AN) being at least one of: a) engagable, via the second shifting component (B), with the sun gear (SO 1 ) of the first planetary gearset (RS 1 ) and b) engagable, via the fifth shifting component (E), with the carrier (ST 1 ) of the first planetary gearset (RS 1 ); at least one of the sun gear (SO 1 ) of the first planetary gearset (RS 1 ) being engagable, via the third shifting component (C), with the transmission housing (GG) and the carrier (ST 1 ) of the first planetary gearset (RS 1 ) being engagable, via the fourth shifting component (D), with the transmission housing (GG); wherein one of: i) the output shaft (AB), the ring gear (HO 1 ) of the first planetary gearset (RS 1 ) and the carrier (ST 3 ) of the third planetary gearset (RS 3 ) are connected with one another; the carrier (ST 2 ) of the second planetary gearset (RS 2 ) is connected with the ring gear (HO 3 ) of the third planetary gearset (RS 3 ), and the carrier (ST 1 ) of the first planetary gearset (RS 1 ) is connected with the ring gear (HO 2 ) of the second planetary gearset (RS 2 ), and ii) the output shaft (AB), the ring gear (HO 1 ) of the first planetary gearset (RS 1 ) and the carrier (ST 2 ) of the second planetary gearset (RS 2 ) are connected with one another, and the carrier (ST 3 ) of the third planetary gearset (RS 3 ) is connected with the ring gear (HO 2 ) of the second planetary gearset (RS 2 ), and the carrier (ST 1 ) of the first planetary gearset (RS 1 ) is connected with the ring gear (HO 3 ) of the third planetary gearset (RS 3 ); one shaft axially passes centrally through the second planetary gearset (RS 2 ); and the first shifting component (A) is a multidisk brake; the second shifting component (B) and the fifth shifting component (E) are axially located between the first planetary gear set (RS 1 ) and the second planetary gear set (RS 2 ); and the fourth shifting component (D) is radially arranged above the first planetary gearset (RS 1 ), the second planetary gearset (RS 2 ) and the third planetary gearset (RS 3 ).
