摘要： A transmission (G) for a motor vehicle includes an electric machine (EM1), a first input shaft (GW1), a second input shaft (GW2), an output shaft (GWA), three planetary gear sets (P1, P2, P3), and at least six shift elements (A, B, C, D, E, F). Different gears are implementable by selectively actuating the at least six shift elements (A, B, C, D, E, F), and different operating modes are implementable by selectively actuating the at least six shift elements (A, B, C, D, E, F) in interaction with the electric machine (EM1). A drive train for a motor vehicle with the transmission (G) and a method for operating the transmission (G) are also provided.

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 (51, 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 power-split transmission (28) with a first power path and a second power path. In this case, the first power path is a mechanical power path and includes a primary planetary gearset (P1), a secondary planetary gearset (P2) and a tertiary planetary gearset (P3). Furthermore, the power-split transmission (28) is equipped with at least four shifting elements. In addition, a method for operating such a power-split transmission (28) is disclosed. Moreover, a drive-train (10) of a working machine with a power-split transmission (28) of the type concerned is presented.

摘要： A power-split transmission comprises an electric variator (9) and an electric variator (10) which can be connected, by way of a clutch (8), for forward driving, and a clutch (7), for reverse driving, to the drive output shaft (5) in such manner that the drive output shaft (5) can be purely electrically driven even when the input shaft (2) is static.

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).
