Gear unit for a vehicle and powertrain with such a gear unit

A powertrain for a vehicle, comprising:

• a gear unit comprising:
• an input shaft;
• a first output shaft;
• a second output shaft;
• and
• an integral differential operatively arranged between the input shaft and the two output shafts, comprising:
• a first planetary gearset with a plurality of first gearset elements;
• and
• a second planetary gearset with a plurality of second planetary gearset elements, the second planetary gearset being operatively connected to the first planetary gearset;
• and
• an epicyclic gear train having a plurality of epicyclic gearset elements, wherein one of the epicyclic gearset elements is connected in each instance to an input of the epicyclic gear train, an output of the epicyclic gear train and a stationary structural component of the gear unit to be fixed with respect to relative rotation,
• wherein:
• a first gearset element of the first planetary gearset is connected to the input shaft to be fixed with respect to rotation relative to it,
• a second gearset element of the first planetary gearset is connected to the first output shaft to be fixed with respect to rotation relative to it, and
• a third gearset element of the first planetary gearset is at least indirectly connected to a first gearset element of the second planetary gearset so as to be fixed with respect to rotation relative to it,
• wherein:
• a second gearset element of the second planetary gearset is at least indirectly connected or connectible to a second gearset element of the epicyclic gear train to be fixed with respect to rotation relative to it, and
• a third gearset element of the second planetary gearset is connected to the second output shaft to be fixed with respect to rotation relative to it,
• wherein
• a first gearset element of the epicyclic gear train is connected or connectible to the input shaft to be fixed with respect to rotation relative to it, and
• a third gearset element of the epicyclic gear train is connected or connectible to the stationary structural component to be fixed with respect to rotation relative to it,
• wherein a first output torque is transferable to the first output shaft by the first planetary gearset,
• wherein a reaction torque of the first planetary gearset is transformable in the second planetary gearset such that a second output torque corresponding to the first output torque is transferable to the second output shaft;
• and
• a drive unit, operatively connected to the gear unit.
