Gearwheel for structure-borne sound reduction in electric drives, having a toothed ring and a wheel hub, which has a structured annular or corrugated web between a shaft seat and the toothed ring. The web has a structure designed with deviations from uniform stiffness and mass distribution about an axis of rotation of the gearwheel, and has an axial symmetry to avoid imbalance. The gearwheel has a two-fold, four-fold, six-fold or eight-fold cyclic axial symmetry.

Gearwheel for reducing structure-borne sound in electric drives

A portal axle drive for a vehicle axle of an electric vehicle with driving wheels includes a drive shaft (AN) with an input axis (a) and an output shaft (AB) with an output and wheel axis (b). The input axis (a) and the output axis (b) have an axial or portal offset (c). A first gear stage (&#xdc;) is arranged between the drive shaft (AN) and the output shaft (AB). In an axial direction, a second gear stage (&#xdc;) is arranged next to the first gear stage (&#xdc;) and an engagement device (SE) is arranged next to the second gear stage (&#xdc;). The first gear stage (&#xdc;) and the second gear stage (&#xdc;) are engageable via the engagement device (SE).
