Abstract
A gearing arrangement that offers a new way to operate an electric motor at a favorable operating point is provided. 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 (i), such that the drive torque path in a first operating state of the gear arrangement () runs via the first transmission gearing stage (); and including a second transmission gearing stage (), such that the drive torque path in a second operating state of the gear arrangement () runs via the second transmission gearing stage (), the second transmission gearing stage () having a continuously variable transmission ratio (i. . . i).
