An electromotive transmission device for a vehicle having an electric motor (2) comprising a stator winding (7) and a rotor (5). A drive shaft is driven by an input shaft (12) via a transmission. The transmission is arranged coaxially with the input shaft (12) and the electric motor (2). The stator winding (7) can be cooled by a cooling unit. The transmission has an annular support component, which is joined to the inner face of the radial end wall (11). Pressurized oil is supplied to a radially running annular passage (18) arranged in the end wall (11) and/or the annular support component. A plurality of spray outlets (19) are distributed around the circumference of the annular passage (18) or a radially running slot-like spray outlet. The spray or sprays from the spray outlets (19) are directed at the stator winding (7) and/or the rotor.
