TRANSMISSION ARRANGEMENT FOR A MOTOR VEHICLE AND METHOD FOR OPERATING A HYBRID VEHICLE

The invention relates to a transmission arrangement () for a hybrid vehicle, comprising a housing (), a transmission input shaft () and at least one transmission output shaft (), a first planetary transmission set (PG) having a first sun gear (zs), a first ring gear (zr) and a first planet carrier (c) for a first planetary gear set (zp) meshing with the first sun gear (zs) and the first ring gear (zr), also comprising a second planetary transmission set (PG) having a second sun gear (zs), a second ring gear (zr) and a second planet carrier (c) for second planetary gear set (zp) meshing with the second sun gear (zs) and the second ring gear (zr), wherein the transmission input shaft () is rotationally fixed to the first planet carrier (c), and the first ring gear (zr) and the second ring gear (zr) are permanently connected to one another and are rotationally fixed to the transmission output shaft (), further comprising a first electric machine (E) and a second electric machine (E), wherein the first electric machine (E) is in permanent driving engagement with first sun gear (zs) and the second electric machine (E) is in driving engagement with the second sun gear (zs) in at least one operating mode, and wherein the first sun gear (zs) can be connected to the housing () via a first switching element (S). According to the invention, the second planet carrier (c) is fixedly connected to the housing () and the second electric machine (E) is drivingly engaged or can be drivingly engaged to the second sun gear (zs).
