  • Publication number: 20230137376
    Abstract: A transmission (G) for a motor vehicle includes an electric machine (EM), a first input shaft (1), a second input shaft (5), an output shaft (2), three planetary gear sets (11, 12, 13), and at least four shift elements (SE1, SE2, SE3, SE4). Different gears are selectable by selectively actuating the at least four shift elements (SE1, SE2, SE3, SE4) and, in addition, in interaction with the electric machine (EM), different operating modes are implementable.

    Abstract: A hybrid transmission arrangement for a motor vehicle (30) includes a first transmission group (12), a second transmission group (18), a third planetary gear set (PS3), and a first electric machine (EM1). The first transmission group (12) includes a first input (14), a first output (16), and a first planetary gear set (PS1). The first input (14) is connectable to an internal combustion engine (VM). The second transmission group (18) includes a second input (20), a second output (22), and a second planetary gear set (PS2). The second input (20) is connected to the first output (16) of the first transmission group (12). The third planetary gear set (PS3) includes a first element (S3;H3I), a second element (H3;S3I), and a third element (P3;P3I). The third planetary gear set (PS3) is interlockable using a first shift element (E) and arranged coaxially to a first axis (A1). The first element (S3;H3I) is connected to the first electric machine. The second element (H3;S3I) is connected to the second output (22).

  • Publication number: 20230104464
    Abstract: A hybrid transmission arrangement (10) for a motor vehicle (30) includes a transmission (11), a third planetary gear set (PS3), and a first electric machine (EM1). The transmission (11) includes a first input (14), which is connectable to an internal combustion engine (VM), a second output (22), a third output (23), and at least one planetary gear set (PS1, PS2). The third planetary gear set (PS3) includes a first element (S3;H3?), a second element (H3;S3?), and a third element (P3;P3?). The third planetary gear set (PS3) is interlockable using a first shift element (E) and arranged coaxially to a first axis (A1). The first element (S3;H3?) is connected to the first electric machine. The second element (H3;S3?) is connected to the second output (22) of the transmission (11). The third output (23) of the transmission (11) is connected to the first element (S3;H3?). The third element (P3;P3?) is connected to a drive output (Ab) of the hybrid transmission arrangement (10).

  • Patent number: 11313442
    Abstract: A range-change transmission device, which is a splitter transmission, includes an input shaft, an output shaft, a countershaft, at least one planetary gear set, and a torque adjustment device. A first transmission element of the planetary gear set is arranged coaxially to the output shaft. A second transmission element of the planetary gear set is or can be directly coupled to the countershaft. A third transmission element of the planetary gear set is permanently coupled to the input shaft in a rotationally fixed manner. The countershaft is or can be coupled to the torque adjustment device. The range-change transmission device has a first switching unit, which is provided to couple the countershaft to the output shaft.

  • Patent number: 11149824
    Abstract: An electric drive for a motor vehicle includes a housing, an output shaft, an electric engine, which has a stator and a rotor rotatable relative to the stator, a planetary gear set arranged in the housing, which has a sun gear, a ring gear and a planetary carrier, which is non-rotatably connected to the output shaft, having a first switching element, by means of which the ring gear can be non-rotatably coupled to the rotor, and a second switching element, by means of which the ring gear can be non-rotatably coupled to the housing. The first switching element and the second switching element are coupled to each other via a first coupling element and thereby can be operated together by a single first actuator common to the first switching element and the second switching element.
