Abstract

A transmission has an input shaft, first and second output shafts, and first and second planetary gear-set, connected together. The first output shaft is rotationally fixed to a first planetary gear-set second element, the second output shaft is rotationally fixed to a second planetary gear-set third element, a first planetary gear-set third element is rotationally fixed to a second planetary gear-set first element via a shaft, and a second planetary gear-set second element is secured to a rotationally fixed component. A first shift element blocks the third planetary gear-set by connecting third planetary gear-set elements in a rotationally fixed manner, a second shift element secures a third planetary gear-set first element to the rotationally fixed component, a third planetary gear-set second element is rotationally fixed to the first planetary gear-set first element via an intermediate shaft, and a third planetary gear-set third element is rotationally fixed to the input shaft.
