摘要： A transmission (G) includes an input shaft (GW1), an output shaft (GW2), an electric machine (EM), a plurality of planetary gear sets (P1-P3; 2P1-2P5), and gear-implementing shift elements (S1-S6; 2S1-2S5). Via engagement of a first of the gear-implementing shift elements (S1, 2S1), which is a force-locking shift element having a variable torque transmission capacity, the input shaft (GW1) and an element (E1, 22E1) of one of the planetary gear sets (P3; 2P4) can be brought into a fixed rotational speed relationship with respect to each other. Another element (E2, 22E2a, 22E2b) of one of the planetary gear sets (P1, 2P3, 2P5) is permanently connected to a rotor (R) of the electric machine (EM). By engaging an auxiliary shift element (ZS, 2ZSa, 2ZSb), which is a form-locking shift element, the rotor (R) and the input shaft (GW1) can be brought into a fixed rotational speed relationship with respect to each other.

摘要： A transmission (G) for a motor vehicle includes an input shaft (GW1), an output shaft (GW2), a front-mounted gear set (VRS) with a first planetary gear set (P1) and a second planetary gear set (P2), a main gear set (HRS), an electric machine (EM) with a stator (S) and a rotor (R), and a plurality of shift elements. By selective engagement of three of the shift elements in each case, a plurality of fixed transmission ratios between the input shaft (GW1) and the output shaft (GW2) are shiftable. The two planetary gear sets (P1, P2) of the front-mounted gear set (VRS) include, in addition to the first shaft (Wx1) and the second shaft (Wx2), precisely three further shafts, namely a third shaft (Wx3), a fourth shaft (Wx4), and a fifth shaft (Wx5). A drive train for a motor vehicle may include such a transmission (G).

摘要： A transmission for a motor vehicle has an input shaft, output shaft, first and second minus planetary gear sets, and first electric machine with a rotationally fixed stator and a rotatable rotor connectable to the input shaft. The first planetary gear set is stepped and has planet gears of a larger and a smaller effective diameter. In the first planetary gear set, first sun gear engages the larger planet gears and is connected or connectable to the rotor; second sun gear engages the smaller planet gears and is connected to a sun gear of the second planetary gear set and connectable to the input shaft; a carrier is connected to a ring gear of the second planetary gear set; and a ring gear is rotationally fixable. In the second planetary gear set, the carrier is connectable to the input shaft and the ring gear is connected to the output shaft.

摘要： A transmission includes a main gear set, an auxiliary gear set and an electric motor with a rotor and a stator. A third shaft of the main gear set is connected to a transmission output shaft, and a first shaft of the auxiliary gear set is connected to the rotor. When a second shaft of the auxiliary gear set is connected to a first shaft of the main gear set, a third shaft of the auxiliary gear set is constantly connected to the third shaft of the main gear set or a fourth shaft of the main gear set. When the second shaft of the auxiliary gear set is connected to the third shaft of the main gear set, the third shaft of the auxiliary gear set is constantly connected to the fourth shaft of the main gear set.

摘要： A transmission (G) for a motor vehicle includes a drive shaft (GW1), an output shaft (GW2), a first and a second planetary gear set (P1, P2), and a first, second, third, fourth and fifth shift element (04, 13, 14, 26, 36). Six forward gear ratios (1-6) between the drive shaft (GW1) and the output shaft (GW2) are engagable through selective pairwise closure of the five shift elements (04, 13, 14, 26, 36) and rotationally fixed immobilization of the sun gear (E11) of the first planetary gear set (P1).

The output shaft is connected with the differential transmission by a chain drive and a downstream gear set coaxial to the differential transmission. The electric motor is at an axial end of the transmission where the interface to the drive unit is formed. The rotor is connected with the drive shaft. The chain drive is axially between the differential transmission and the downstream gear set or the downstream gear set is axially between the chain drive and the differential transmission, and the chain drive is axially between the electric motor and the downstream gear set.
