摘要：
An eight-gear transmission comprises an input and output shaft, four planetary gearsets, eight shafts and five shifting elements. A ring gear of the gearset (RS4) and the input shaft are coupled as the first shaft. A ring gear of the gearset (RS2), a carrier of the gearset (RS3), and the output shaft are coupled as the second shaft. A sun gear of the gearset (RS1) and a sun gear of the gearset (RS4) are coupled as the third shaft. A ring gear of the gearset (RS1) forms the fourth shaft. A sun gear of the gearset (RS3) forms the fifth shaft. A carrier of the gearset (RS1) and a ring gear of the gearset (RS3) are coupled as the sixth shaft. A sun gear of the gearset (RS2) and a carrier of the gearset (RS4) are coupled as the seventh shaft. A carrier of the gearset (RS2) forms the eighth shaft.
