Claim 0:
1. A drive unit for a drive axle of a vehicle comprising a first electric machine, a second electric machine, a differential with a differential input and two differential output shafts configured to be drivingly connected with respective drive wheels of the drive axle, and a transmission, the drive unit comprising:
a first transmission input shaft for connection to the first electric machine;
a second transmission input shaft for connection to the second electric machine;
a transmission output shaft for connection to the differential;
at least a first planetary gearset with a first element, a second element and a third element;
a first shifting unit with exactly three shift positions, such that in a first shift position of the first shifting unit, the second element of the first planetary gearset is connected to a rotationally fixed component, in a second shift position of the first shifting unit two of the three elements of the first planetary gearset are connected rotationally fixed to one another, and a third shift position of the first shifting unit is a neutral position; and
a second shifting unit with exactly three shift positions, such that in a first shift position of the second shifting unit the first transmission input shaft and the second transmission input shaft are connected rotationally fixed to one another, in a second shift position of the second shifting unit the second transmission input shaft is connected at least indirectly to the second element of the first planetary gearset, and the third shift position of the second shifting unit is a neutral position.
