Patent ID: 8262530

Claim:
A power-branched transmission comprising: an input shaft ( 2 ) being driven by a drive motor ( 1 ), a summation planetary gear set ( 5 ) having only a single ring gear ( 8 ) and at least one sun gear ( 7 , 21 , 22 ), the summation planetary gear set ( 5 ) having a double planetary gear ( 6 ), an axis of rotation of the sun gear ( 7 , 21 , 22 ) being spaced from an axis of rotation of the input shaft ( 2 ), an infinitely adjustable variator ( 10 ) having a first shaft ( 9 ) and a second shaft ( 11 ), the first shaft ( 9 ) being connected, in a rotationally fixed manner, to the sun gear ( 7 , 21 ) and the second shaft ( 11 ) being operatively connected to the ring gear ( 8 ) via a spur gear ( 12 ), the sun gear ( 7 , 22 ) being connectable to an output shaft ( 16 ) via at least a first shift element ( 18 ), and the ring gear ( 8 ) being connectable to the output shaft ( 16 ) via direct connection to at least a second shift element ( 13 ).
