Patent ID: 8287414

Claim:
A transmission device ( 3 ) having at least one variator ( 5 ) for the continuous variation of a gear ratio and having secondary power splitting; a planetary gear set ( 8 ) being provided for power splitting; a first shaft ( 9 ) of the planetary gear set ( 8 ) being coupled to a transmission input ( 6 ); a second shaft ( 10 ) of the planetary gear set ( 8 ) being coupled to a first shaft ( 12 ) of the variator ( 5 ); a third shaft ( 11 ) of the planetary gear set ( 8 ) being coupled to a second shaft ( 13 ) of the variator ( 5 ); at least one of a first shift element ( 14 ) and a second shift element ( 15 ) being provided for switching between a first gear ratio range and a second gear ratio range, within which the gear ratio is continuously varied by the variator ( 5 ), and the first and the second gear ratio ranges at least partially overlap one another; the second shaft ( 10 ) of the planetary gear set ( 8 ) being connected, via the first shift element ( 14 ), to a transmission output ( 7 ) in order to implement the first gear ratio range; the third shaft ( 11 ) of the planetary gear set ( 8 ) being directly connected to the second shift element ( 15 ), and being connectable, via the second shift element ( 15 ), to the transmission output ( 7 ) in order to implement the second gear ratio range; at least one idler gear ( 16 ) being rigidly connectable, via one of the first and the second shift elements ( 14 , 15 ), to one of the second shaft ( 13 ) of the variator ( 5 ) and the third shaft ( 11 ) of the planetary gear set ( 8 ); and the second shaft ( 10 ) of the planetary gear set ( 8 ) being one of directly connected to the first shift element ( 14 ), and directly coupled to at least one idler gear ( 29 , 31 ).
