1. A hybridized drivetrain for a motor vehicle, having a combustion engine, an electric machine and a gearbox assembly, wherein the gearbox assembly has at least one first planetary gear set and is configured as a summation gearbox, wherein:
a first ring gear of the first planetary gear set is rotatably connectable to the combustion engine and fixable to a housing;
first sun gear of the first planetary gear set is rotatably connectable to the electric machine and fixable to the housing with a first clutch;
a first planet carrier of the first planetary gear set is connected to an output;
wherein the first ring gear is furthermore connectable to the electric machine with a second clutch, wherein the first clutch has a first output disk carrier which is connected to the first sun gear of the first planetary gear set, wherein the second clutch has a second output disk carrier which is connected to the first ring gear of the first planetary set, and wherein an input disk carrier and the second output disk carrier are mounted so as to be mutually rotatable;
wherein the first and second clutches configure a double-clutch assembly and have a common clutch input side, wherein the common clutch input side is rotatably connected to the electric machine;
wherein the common clutch input side comprises the input disk carrier which carries disks assigned to the first clutch as well as to the second clutch;
wherein the first sun gear of the first planetary gear set is fixable in relation to the housing by means of a first brake, and the common clutch input side of the double-clutch assembly is connected to the electric machine by way of a gear wheel stage, and wherein the gear wheel stage is disposed axially between the first brake and the double-clutch assembly.
