A power-split, continuously variable transmission device (1) with a summing planetary transmission (9), with at least one additional planetary gear set (10) and with one variator (8), which are in operative connection with each other in the area of shafts (11, 12, 13, 14) and can be coupled to each other by means of shift elements (S1 bis S3) for the presentation of at least three transmission ratio ranges in the area of additional shafts (15, 16, 11, 18, 14), is described. A transmission ratio is continuously variable within the transmission ratio ranges by means of the variator (8). The variator (8) is formed as a mechanical friction wheel variator with at least three shafts (11, 15, 17). The summing planetary transmission (9), the at least one additional planetary gear (10) and the variator (8) are arranged in a manner coaxial to each other. In one of the transmission ratio ranges, the total power can be guided between a transmission input shaft (2) and a transmission output shaft (7) by means of the variator (8). In addition, a friction wheel (26) of the variator (8) is designed to be at least approximately cone-shaped, at least in sections. |
