Title: AUTOMATIC TRANSMISSION
Abstract:
The transmission (GE) has five planetary gear sets (RS1 to RS5). A second element (ST2) of the second gear set (RS2) forms a transmission input shaft (AN), a second element (ST4) of the fourth planetary gear set (RS4) forms a transmission output shaft (AB). A first element (SO1) of the first gear set (RS1) is connected to a third element (HO5) of the fifth gear set (RS5) and is immobilizable by means of a first shift element (A). A second element (ST1) of the first gear set (RS1) is connected to a third element (HO4) of the fourth gear set (RS4). A third element (HO1) of the first gear set (RS1) is immobilizable by means of a second shift element (B). A first element (SO4) of the fourth gear set (RS4) is connectable by means of a third shift element (C) to a second element (ST2) of the second gear set (RS2). A third element (HO2) of the second gear set (RS2), a first element (SO3) of the third gear set (RS3) and a first element (SO5) of the fifth gear set (RS5) are connected to one another and are connectable by means of a fifth shift element (E) to the first element (SO4) of the fourth gear set (RS4). One element of the fourth gear set (RS4) is connected to one element of the third gear set (RS3), whereas another element of the fourth gear set (RS4) is connectable by means of a fourth shift element (D) to another element of the third gear set (RS3). A first element (SO2) of the second gear set (RS2) is connected to a second element (ST5) of the fifth gear set (RS5) and is immobilizable by means of a sixth shift element (F).
