Abstract
An infinitely variable transmission device () for a vehicle drivetrain () which includes a variator () and a gearshift transmission device (), which produce gear ratios in a plurality of ratio ranges with continuous variation. The device has a planetary transmission device () in active connection with a transmission input (), in an area of a first shaft (), with the gearshift transmission device (), in an area of a second shaft (), and with the variator (), in an area of a third shaft (). The torque to be transmitted by the transmission device () passes, via at least two power paths, between the transmission input () and a transmission output (). The variator () is arranged in one of the two power paths and the gearshift transmission device () is arranged between the variator () and the transmission output ().
