摘要：
A continuously variable transmission device (1) has a power split which takes place in the area of a sum planetary transmission (9). A first shaft (8) of the sum planetary transmission (9) can be brought into operational connection with a drive engine or machine (3). A second shaft (12) of the sum planetary transmission (9) can be connected, for continuous variation of the gear ratio, with an electric machine (36) which itself can be coupled with an electric energy source (38).
