Abstract
A gearbox has an input shaft, an output shaft, three shifting elements, and three planetary gearsets each having a sun shaft, ring gear shaft, and web shaft. The first sun shaft, the second sun shaft, and the input shaft are connected rotationally fixed. Rotationally fixed connections are made between the first ring gear shaft and a stationary component, the first web shaft and the second ring gear shaft, the second web shaft and the third sun shaft, and the third web shaft and the output shaft. Closing the first shifting element connects the third ring gear shaft rotationally fixed to a stationary component. Closing the second shifting element connects in a rotationally fixed manner the first web shaft, the second ring gear shaft, the third web shaft, and the output shaft. Closing the third shifting element connects rotationally fixed two of the three shafts of the third planetary gearset.
