Abstract: A hybrid transmission (10) for a motor vehicle drive train with an internal combustion engine (55) and an electric prime mover (18) is provided. The hybrid transmission (10) includes a first sub-transmission (10a) with multiple gear steps and a first transmission input shaft (12), a second sub-transmission (10b) with multiple gear steps and a second transmission input shaft (14), a countershaft (16), multiple shift elements (A, B, C, D, E) for engaging the gear steps (1, 2, 3, 4, 5), and gearwheel pairs of idler gears (28, 32, 36, 40, 44) and fixed gears (26, 30, 34, 38, 42) for forming the gear steps, arranged in multiple gear set planes. A portion of the gear steps is engageable for the internal combustion engine, and a portion of the gear steps is engageable for the electric prime mover. The gearwheel pairs for forming the gear steps having the lowest and the second-lowest ratios are fixedly associated with the first sub-transmission.

Abstract: 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.

Abstract: 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), two planetary gear sets (P1, P2, P3), and at least five shift elements (A, B, C, D, E). Different gears are implementable by selectively actuating the at least five shift elements (A, B, C, D, E) and, in addition, in interaction with the electric machine (EM1), different operating modes are implementable. A drive train for a motor vehicle with the transmission (G) and a method for the transmission (G) are also provided.

Abstract: A motor vehicle transmission, the transmission having an input shaft rotationally fixed to a second element of a first planetary gear set and rotationally fixable to a first element of a second planetary gear set by a first shift element. A first element of the first planetary gear set is rotationally fixable to a housing of the transmission by a second shift element and to the first element of the second planetary gear set by a third shift element. An output shaft of the transmission is rotationally fixed to a third element of the first planetary gear set and to a second element of the second planetary gear set. A third element of the second planetary gear set is rotationally fixable to the housing by a fourth shift element.
