ABSTRACT:
The multi-speed transmission having rotatable shafts, planetary gearsets (RS1, RS2, RS3, RS4) and shifting elements (A, B, C, D, E). Carrier (ST4) of gearset (RS4) and the input shaft couple as shaft (1). Carriers (ST2, ST3) of respective gearsets (RS2, RS3) and the output shaft (AB) couple as shaft (2). Sun gears (SO1, SO4) of gearsets (RS1, RS4) couple as shaft (3). Carrier (ST1) of gearset (RS1) forms shaft (4). Sun gear (SO3) forms shaft (5). Ring gears (HO1, HO3) of gearsets (RS1, RS3) couple as shaft (6). Sun and ring gears (SO2, HO4) respectively of gearsets (RS2, RS4) couple as shaft (7). Ring gear (HO2) is shaft (8). In the flow of power, elements (A, B) are respectively between shafts (3, 4) and a transmission housing; element © is between shafts (1, 5); element (D) is between shafts (5, 8); and element (E) is between shafts (5, 7).
