Abstract
A shift gearbox (1) has two gears. An input shaft (2) of the gearbox (1) can be driven by an electric machine (3). The input shaft (2) is connected via at least one single-direction clutch (4) to an output shaft (5) of the gearbox (1). A planetary stage (6) arranged parallel to the clutch (4) is connected to the output shaft (5) of the gearbox (1) for driving a wheel (30) of a motor vehicle, or an axle (7) that has wheels (30). The planetary stage (6) is switchable. A shift gearbox of this type permits simple shifting of the gears of the gearbox while being of simple design.
