摘要：
A multi-speed transmission having four gearsets, eight shafts and six shifting elements. The sun gear of gearset (P2) couples, via shaft (5) and brake (05), the housing (G), and, via clutch (15) the drive shaft. The carriers of gearsets (P2, P3) communicate, via shaft (4) and brake (04), with housing (G), and the sun gear of gearset (P3) communicates, via shaft (8) and clutch (18), with the drive shaft. The ring gears of gearsets (P2, P3) communicate, via shaft (6), with the ring gear of gearset (P4) and the sun gear of gearset (P1). The ring gear of gearset (P4) and the sun gear of gearset (P1) are connected with one another. The sun gear of gearset (P4) communicates, via shaft (3) and brake (03), with housing (G). The carriers of gearsets (P1, P4) communicate, via shaft (7) and clutch (17), with the drive shaft and the output shaft couples the ring gear of gearset (P1).
