| description | The invention relates to a lightweight gear body (1) for an electric drive, in particular in an electric drive for a passenger vehicle, having reduced structural noise. The aim of the invention is to seek a solution for the design of a gear body in a lightweight design that reduces structural noise for an electric drive, in which a contact spot movement of the gear body under load is minimized. In the gear body (1), the gear body has a structured bridge (14) extending substantially within a radial plane between the axle seat (13) and the ring gear (11), the bridge (14) having a rib-thickened helical structure (3; 5), and the helical structure (3; 5) is oriented in such a way that the helical shape thereof reaches at least at the ring gear (11) at an inclined angle. The invention further relates to a transmission device, to an electric axle drive for a motor vehicle, and to a motor vehicle.
