Hybrid drive configuration for a motor vehicle

A hybrid drive configuration for a motor vehicle, comprising:

• a transmission housing;
• a first and a second electric machine each having a rotor and each having a stator fixedly connected to said transmission housing, said first and said second electric machine each being operable both in a motor mode and in a generator mode and, by way of power electronics, being connectable to one another and to an electrical energy store;
• an input shaft, which is connectable to an internal combustion engine, and an output shaft, which is connectable to a drivetrain output section;
• a first brake and a second brake;
• a first clutch and a second clutch;
• a first planetary gear set having a sun gear, a web, and an internal gear, said sun gear of said first planetary gear set being connected to said rotor of said second electric machine, said web of said first planetary gear set being connected to said output shaft, and said internal gear of said first planetary gear set being coupled by way of said first brake to said transmission housing;
• a second planetary gear set having a sun gear, a web, and an internal gear, said sun gear of said second planetary gear set being both coupled by way of said first clutch to said internal gear of said first planetary gear set and connected to said rotor of said first electric machine, said web of said second planetary gear set being coupled by way of said second clutch to said web of said first planetary gear set, and said internal gear of said second planetary gear set being connected to said input shaft;
• and
• a third planetary gear set having a sun gear, a web, and an internal gear, said web of said third planetary gear set being connected to said input shaft, wherein
• either said sun gear of said third planetary gear set or said internal gear of said third planetary gear set is connected to said rotor of said first electric machine, and
• correspondingly either said internal gear of said third planetary gear or said sun gear of said third planetary gear set is coupled by way of said second brake to said transmission housing,
• or
• said sun gear of said third planetary gear set is coupled by way of said second brake to said transmission housing, wherein
• either said web of said third planetary gear set or said internal gear of said third planetary gear set is connected to said input shaft, and
• correspondingly either said internal gear of said third planetary gear set or said web of said third planetary gear set is connected to said web of said second planetary gear set.
