Abstract

A combined multistage gearing has a spur gearing having at least one first and one second spur wheel arranged on a spur gear shaft, an epicyclic gearing having at least one first and one second, in particular reduced, planetary wheel set and an epicyclic gearing shaft, wherein at least one of the planetary wheel sets is arranged concentrically to the epicyclic gearing shaft, a gearing housing, wherein the spur gear shaft and the epicyclic gearing shaft are rotatably mounted relative to the gearing housing, and a plurality of switching apparatuses. The first spur gear can be selectively connected in a torque-transmitting manner to the spur gear shaft. The first spur gear can be selectively connected in a torque-transmitting manner to the gearing housing.
