Electric drive system for a motor vehicle

An electric drive system for a motor vehicle, the electric drive system comprising:

• an electric motor comprising a rotor, which includes a rotor shaft;
• a planetary transmission stage comprising a sun gear, a planet carrier and associated planetary gears, and a ring gear, wherein the rotor shaft is connected or is connectable to the sun gear in a torque-transmitting manner, wherein the planet carrier has a carrier shaft arranged coaxially and axially adjacent to the rotor shaft, wherein the carrier shaft is mounted relative to a housing by a first bearing, wherein the housing has a circular opening through which the carrier shaft is guided, wherein the housing has a first oil duct opening into the circular opening, wherein the carrier shaft has a rotary feedthrough in an axial region of the opening relative to an axis of rotation of the carrier shaft, wherein the carrier shaft has at least one first bore extending in the axial direction, wherein the at least one first bore is connected at one end to the rotary feedthrough, wherein the rotor shaft has an axially extending second bore, wherein the first bore is connected to the second bore, and wherein a nozzle, which opens into the second bore, is arranged on an end face of the carrier shaft facing the rotor shaft;
• a retaining ring arranged within the second bore at least partially axially overlapping the nozzle, wherein the retaining ring has, on an end facing the carrier shaft, a disc section extending radially inwards from an inner surface of the second bore, wherein the disc section is completely axially overlapped by the nozzle.
