A transmission (15; 15a; 15b; 15c). In particular for motor vehicles, has two planetary gear sets (16; 16c; 17; 17c;), the ring gears (18; 18c; 19) of which are coupled with the crankshaft (11; 11a; 11c) of an internal combustion engine by means of a toothed ring (12). Each of the planetary gear sets (16; 16c, 17) is coupled with an electrical machine (26, 27) and a transmission shaft (31, 32) on which input gears (1E through 5E, RE) for various conversion ratios are arranged. The input gear wheels (1E through 5E, RE) mesh with output gear wheels (1A through 5A, RA) arranged on an output shaft (40; 40a; 40c). According to the invention, it is provided that the electrical machines and/or the planetary gear sets (16; 16c, 17; 17c) are bridged in order to enhance the overall efficiency level during constant driving conditions. A pair of gear wheels can be used for this purposed, for example, that couples the input shaft (11) with a transmission shaft (31, 32). |
