The shaft arrangement extends into the transmission. The transmission comprises a plurality of transmission components along the shaft arrangement. The components are supplied with fluid for at least one of lubrication and cooling purposes. A radial inlet duct leads from the fluid supply device into the interior of the shaft arrangement. An axial duct extends inside the shaft arrangement. At least one radial outlet duct inside the transmission leads from the axial duct to the transmission components, in order to supply these with fluid.
