Abstract:
An eight gear transmission having drive and output shafts, planetary gearsets, shafts and shifting elements. One carrier of the gearset (RS4) and the drive shaft are coupled to form shaft (1). One ring gear of the gearset (RS2), one carrier of the gearset (RS3) and the output shaft are coupled to form shaft (2). One sun gear of the gearset (RS1) and one sun gear of the gearset (RS4) are coupled to form shaft (3). One carrier of the gearset (RS1) forms shaft (4). One sun gear of the gearset (RS3) forms the fifth shaft. One ring gear of the gearset (RS1) and one carrier of the gearset (RS2) and one ring gear of the gearset (RS3) are coupled to form shaft (6). One ring gear of the gearset (RS4) forms the seventh shaft. One sun gear of the gearset (RS2) forms shaft (8).
