High-End Surfaces of Gears for Electromobility

Conference paper - While the quantity of gears within drive trains for e-mobility has drastically decreased compared to drive trains for vehicles with combustion engines, their design has changed significantly and alongside the geometrical tolerances were massively sharpened. The reasons for this are twofold: With the omission of the noise emission of the motor, the gear boxes acoustic behaviour moved into focus. Furthermore, the range of electric vehicles became an important selling argument, which is why the transmission efficiency of drive trains considerably gained in importance.
