Electric drive system for a motor vehicle, and motor vehicle

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

• a housing having a housing wall;
• an electric engine comprising a stator and a rotor;
• a planetary gearbox comprising
• a first planetary gear set comprising a first sun gear, a first planetary carrier, and a first ring gear;
• and
• a second planetary gear set comprising a second sun gear, a second planetary carrier, and a second ring gear, wherein the second planetary gear set is arranged radially outside and axially overlapping the first planetary gear set with regard to a rotational axis of the planetary gearbox;
• a first brake switching element configured to connect the first ring gear to the housing wall to conjointly rotate, wherein a housing-side switching half of the first brake switching element is arranged on the housing wall;
• and
• a differential gear comprising a first crown wheel, a second crown wheel, and pinion gears, wherein the pinion gears arranged axially between the first and second crown wheels and mesh with the first and second crown wheels, wherein the pinion gears are in each case are arranged on a respective bearing bolt connected to the first planetary carrier to conjointly rotate and to the second ring gear to conjointly rotate, wherein the housing wall is a radially extending housing wall arranged axially adjacent to the planetary gearbox;
• and
• a one-piece carrier element comprising a plate section, a first cylinder section, and a second cylinder section, wherein planetary gear bolts for first planetary gears of the planetary gearbox are arranged on the plate section, wherein the second ring gear is arranged on a radial inner side of the first cylinder section, and wherein the bearing bolts are arranged as pinion bolts for the pinion gears on a radial inner side of the second cylinder section,
• wherein the rotor, the housing wall, the planetary gearbox, the first crown wheel, and the second crown wheel are arranged successively in the following order with regard to the rotational axis of the planetary gearbox-the rotor, the housing wall, the planetary gearbox, the first crown wheel, and the second crown wheel.

A motor vehicle comprising:

• first and second vehicle wheels;
• and
• an electric drive system coupled to the first and second vehicle wheels, wherein the electric drive system comprises
• a housing having a housing wall;
• an electric engine comprising a stator and a rotor;
• a planetary gearbox comprising
• a first planetary gear set comprising a first sun gear, a first planetary carrier, and a first ring gear;
