1. A hybrid drive device (1) for a motor vehicle, comprising:
an internal combustion engine (2);
a first electric motor (4);
a first pinion gear (6) arranged on a shaft of the first electric motor (4);
a second electric motor (5);
a second pinion gear (6′) arranged on shaft of the second electric motor (5);
a transmission, comprising
a first partial transmission (9) having
a first drive shaft (7),
a first input gear (8) mounted on the first drive shaft (7),
a first small output gear (13), and
a first large output gear (14), the first small output gear (13) and the first large output gear (14) being selectively coupleable to the first drive shaft (7), and
a second partial transmission (9′) having
a second drive shaft (7′),
a second input gear (8′) mounted on second drive shaft (7′),
a second small output gear (13′), and
a second large output gear (14′), the second small output gear (13′) and the second large output gear (14′) being selectively coupleable to the second drive shaft (7′); and an output shaft (11) of the hybrid drive device (1), the output shaft (11) being
coupled to the first partial transmission (9) by a gear-wheel mesh with the first small output gear (13) and by a gear-wheel mesh with the first large output gear (14) and being
coupled to the second partial transmission (9′) by a gear-wheel mesh with the second small output gear (13′) and by a gear-wheel mesh with the second large output gear (14′), wherein at least two different transmission ratios between the two electric motors (4, 5) and the output shaft (11) can be specified with the transmission,
wherein the first electric motor (4) is connected to the first partial transmission (9) by a gear-wheel mesh of the first pinion gear (6) with the first input gear (8), and
wherein the second electric motor (5) is connected to the second partial transmission (9′) by a gear-wheel mesh of the second pinion gear (6′) with the second input gear (8′), and
wherein the internal combustion engine (2) can be selectively uncoupled from the transmission or coupled to at least one partial transmission (9, 9′), and
wherein the internal combustion engine (2) is connectable simultaneously to the first partial transmission (9) and to the second partial transmission (9′).
