Abstract

A gear mechanism includes at least a first and a second shaft, and at least a first and a second switching group arranged between the first and the second shafts. Each of the switching groups includes at least two transmission units which are individually switched and have a different transmission ratio. The first switching group is movable into active connection with the first shaft by a planetary stage which is constructed such that a mechanical power which is introduced via the first shaft is transmitted to the second shaft via a first or a second power path. At least one transmission unit of the first switching group is associated with each power path and in at least one switching state of the first switching group, the power flow extends over at least one transmission unit of the first and the second power path.
