ABSTRACT:
Structures of automatic vehicle transmissions are described which have a planetary gear train connected to an input shaft. The planetary gear train is connected through a CVT variable speed drive that includes two variable speed drive shafts and through at least one gear pairing to an output shaft. Rotationally fixed connections corresponding to different gear ranges are producible between shafts of the transmission through gear pairings and or shaft connections provided with clutches.
