ABSTRACT:
A multi-step reduction gear with forward reverse gears comprising a drive shaft, a power take-off shaft, three planet sets, rotating shafts as well as six switch elements. The drive shaft is connected with the sun gear of the planetary set and can be connected to the shaft, which is connected to the carrier of the second planetary set and the carrier of the third planetary set. The power take-off shaft is connected with the ring gear of two of the planetary sets, the shaft connected to the carrier of the planetary set to a housing and across the clutches with the shafts is detachably connected. The shaft connected with the shaft of one of the ring gears of the planetary set and is connected with the sun gear of the planetary set and the shaft with the sun gear of the planetary set can be linked to the housing.
