摘要： An electric gear drive (1) is proposed, which comprises a two-speed gearbox (2) and an electric motor (3) coupled to a gear input of the gearbox (2). The gearbox (2) provides a first transmission ratio between the gear input and a gear output of the gearbox (2) in a first gear and a second transmission ratio between the gear input and the gear output in a second gear, wherein provided the same rotation speed at the gear input, the first transmission ratio provides a lower rotation speed at the gear output than the second transmission ratio. First gear wheel toothings (C, D, E), which are engaged and relatively rotate to each other only in first gear, are designed for a lower lifetime than other, second gear wheel toothings (A, B) of the gearbox (2). Moreover, a vehicle (27) with such an electric gear drive (1) is disclosed.
