Abstract

An electric drive system for a motor vehicle includes a housing, an electric motor, a planetary gearbox, and an axle drive. The planetary gearbox has exactly one sun gear and exactly one planetary carrier, which carries a set of first planetary gears and a set of second planetary gears, the first planetary gears have a larger diameter than the second planetary gears. Exactly one ring gear is provided that engages with the second planetary gears. A first freewheel is provided between the ring gear and the housing so that the ring gear is coupled to the housing to block rotation of the ring gear in a forward direction of rotation of the rotor.
