    摘要： A gear unit includes: a stepped planetary gearset, and first and second gear shifting elements. The stepped planetary gearset has first and second sun gears, a first ring gear and a plurality of stepped planet gears rotatably mounted at a first planet carrier. The first ring gear is connected to an output shaft of the gear unit thus being fixed with respect to rotation relative to it. The first planet carrier is connected to a housing and fixed with respect to rotation relative to it. The first gear shifting element drivingly connects the second sun gear to an electric machine in a closed state, and the second gear shifting element drivingly connects the first sun gear to an electric machine in a closed state. One of the two gear shifting elements is in the closed state for driving the output shaft in rotation.

    摘要： A drive train (10) for a motor vehicle includes a dual-clutch assembly (14) with a first clutch (K1) and a second clutch (K2), which include a shared input element (EG). The dual-clutch assembly (14) is connectable to an internal combustion engine (12). The first clutch (K1) includes a first output element (AG1), and the second clutch (K2) includes a second output element (AG2). A first actuating unit (S1) is associated with the first clutch (K1), and a second actuating unit (S2) is associated with the second clutch (K2). A transmission arrangement (16) includes a first sub-transmission (32) and a second sub-transmission (34). An input shaft (24) of the first sub-transmission (32) is connected to the first output element (AG1), and an input shaft (26) of the second sub-transmission (34) is connected to the second output element (AG2). The second actuating unit (S2) is associated with the second clutch (K2) of the dual-clutch assembly (14) as well as with a gearshift clutch (C; E) of the first sub-transmission (32), and/or the first actuating unit (S1″) is associated with the first clutch (K1) of the dual-clutch assembly (14) as well as with a gearshift clutch (F) of the second sub-transmission (34).

    摘要： A transmission arrangement (16) for a motor vehicle drive train (10) includes a first input shaft (24) connected or connectable to an internal combustion engine (12), a second input shaft (26) arranged coaxially to the first input shaft (24), an output shaft connected to the first input shaft (24) via a first plurality of engageable first gear-step gear sets (38, 42, 44) and connected to the second input shaft (26) via a second plurality of engageable second gear-step gear sets (36, 52), a first electric machine (56) connected to the second input shaft (26), a second electric machine (60) connected to the first input shaft (24), and a first clutch (K1) via which the first input shaft (24) and the second input shaft (26) are connectable to each other. The second gear-step gear sets include two alternately engageable gear-step gear sets (36, 52), via each of which an electric motor-driven operation is establishable by the first electric machine (56). The transmission arrangement (16) is configured such that an internal combustion engine-driven operation is establishable via one (36) of the two alternately engageable gear-step gear sets (36, 52) when the first clutch (K1) is engaged.

    摘要： A transmission (1) for an electric drive of a vehicle includes a first input shaft (10), a second input shaft (11), an output shaft (12), two shift elements (3, 4) for connecting the transmission (1) to an electric machine of the electric drive, and a planetary gear set (5) configured as a stepped planetary gear set. A first sun gear (5.1) of the planetary gear set (5) is rotationally fixed to the first input shaft (10). A second sun gear (5.2) of the planetary gear set (5) is rotationally fixed to the second input shaft (11). A ring gear (5.5) of the planetary gear set (5) is fixed at a rotationally fixed component (0) of the transmission (1). A planet carrier (5.6) of the planetary gear set (5) is rotationally fixed to the output shaft (12). A first shift element (3) is configured for connecting the first input shaft (10) to the electric machine of the electric drive. A second shift element (4) is configured for connecting the second input shaft (11) to the electric machine of the electric drive.
