摘要：
A multi-speed automatic planetary transmission for a motor vehicle having an input shaft (AN), an output shaft (AB), four planetary gearsets (RS1, RS2, RS3, RS4), at least eight rotatable shafts (1, 2, 3, 4, 5, 6, 7, 8), and five shifting elements (A, B, C, D, E), the selective engagement of which produces different transmission ratios between the input shaft (AN) and the output shaft (AB), such that eight forward gears and at least one reverse gear are possible. Further, it is possible to connect an electric machine (12) as generator and/or drive, to the fifth shaft (5) by means a drive connection.
