Abstract
A transmission (G) for a motor vehicle includes a housing (GG), a shaft (W, GW, DS, DS) mounted in the housing (GG) and protruding from the housing (GG), a radial shaft seal (DR) having a sealing lip for sealing an oil space (NR) within the housing (GG) with respect to an exterior, a shaft grounding device (E) arranged on an exterior side of the radial shaft seal (DR) for establishing an electrically conductive sliding contact (SK) between the shaft (W, GW, DS, DS) and the housing (GG), and a sleeve-shaped covering element (C) fixedly connected to the shaft (W, GW, DS, DS) for protecting the sliding contact (SK) against environmental influences. The shaft grounding device (E) is fixedly connected to the housing (GG). The covering element (C), together with the grounding device (E), forms a labyrinth sealing. An electric axle drive (EA) may include the transmission (G).
