Zusammenfassung: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. 本发明涉及一种用于电驱动装置的呈降低结构噪声的轻量化结构形式的齿轮体(1)、齿轮体尤其是在用于乘用车的电驱动装置中。本发明的任务是,寻求用于设计电驱动装置的呈降低结构噪声的轻量化结构形式的齿轮体的方案,在其中,使齿轮体在负载下的接触斑点移动最
