Abstract

To meet the challenge of achieving high efficiency for fully electric vehicles, a key focus is on a consistently lightweight design throughout the entire vehicle architecture. As a result of using high-speed electric motors with a lower noise emission as compared to conventional vehicles driven by combustion engines, the design of acoustically inconspicuous axle drives in the powertrain plays a special role. Based on the existing transmission topology of the Visio. M electric vehicle, a new axle gear design is presented, which enables the integration of a reinforced plastic transmission housing into the powertrain. Non-axial force gearings are used, which unload the gearbox system and thus enable the use of lightweight materials in addition to the downsizing of the gearbox components. Furthermore, a special arrangement of the axle drive gears and the design of appropriate tooth flank modifications reduce the excitation level of the gears.
