  • Patent number: 11338663
    Abstract: A transmission (2) of a motor vehicle includes a first input shaft (7) for a first prime mover (3), a second input shaft (8) for a second prime mover (4), and an output shaft (9). A first sub-transmission (5) includes the first input shaft (7) and a countershaft (11) coupled to the first input shaft (7) via a constant ratio. Gearwheels (16, 17, 18) are arranged on the countershaft (11), which mesh exclusively into gearwheels (12, 13, 15) arranged coaxially to the first input shaft (7). At least some of these gearwheels (14, 15) mesh into gearwheels (20, 21) arranged on the output shaft (9). Shift elements (A, B, C, D) are associated with the first input shaft (7) as well as with the countershaft (11), which provide either a gear with a first number of instances of gearwheel meshing or a winding-path gear with a second number of instances of gearwheel meshing. A second sub-transmission (6) includes the second input shaft (8) and is designed as a planetary transmission.
