Motor Vehicle Transmission for a Hybrid Drive Train, and Hybrid Drive Train

A motor vehicle transmission for a hybrid drive train of a motor vehicle, comprising:

• a first transmission input shaft for receiving drive power of a first drive machine;
• a second transmission input shaft for receiving drive power from a second drive machine, wherein the second drive machine is an electromechanical energy converter;
• a first planetary transmission gear set with a first sun pinion, a first internal gear, and a first planetary gear carrier on which a first planetary gear is mounted rotatably;
• a second planetary transmission gear set with a second sun pinion, a second internal gear, and a second planetary gear carrier on which a second planetary gear is mounted rotatably;
• wherein the second transmission input shaft is connected fixedly to the first sun pinion so as to rotate with the first sun pinion;
• wherein the first transmission input shaft is selectively connectable fixedly to the first planetary gear carrier so as to rotate with the first planetary gear carrier or the first transmission input shaft is connected fixedly to the first planetary gear carrier so as to rotate with the first planetary gear carrier;
• a transmission output shaft for an output of drive power from the transmission;
• wherein the transmission output shaft is selectively connectable fixedly to the second internal gear so as to rotate with the second internal gear;
• wherein the first internal gear is connectable fixedly to the second sun pinion so as to rotate with the second sun pinion;
• a first braking device, wherein the first internal gear is selectively connectable fixedly to a transmission housing so as to rotate with the transmission housing by the first braking device;
• and
• a first clutch device, wherein the second internal gear is selectively connectable fixedly to the transmission output shaft so as to rotate with the transmission output shaft by the first clutch device.
