Abstract

A gearing arrangement for an electric motor which is improved in terms of ease of use and efficiency. To this end there is proposed a gearing arrangement for an electric motor of a vehicle, including an input interface for coupling to the electric motor and including an output interface, such that a drive torque path runs between the input interface and the output interface; including a first transmission gearing stage with a first transmission ratio (i1), such that the drive torque path in a first gearshift state runs via the first transmission gearing stage; and including a second transmission gearing stage with a second transmission ratio, such that the drive torque path in a second gearshift state runs via the second transmission gearing stage; and including an intermediate transmission gearing stage with a continuously variable transmission ratio (i1 . . . i2), such that the drive torque path in an intermediate gearshift state runs via the intermediate transmission gearing stage.
