ABSTRACT:
A differential gear includes a drive, in particular a bevel drive pinion, a left output shaft and a right output shaft, a rotatably mounted basket, which is driven by the drive, and which is coupled with the left output shaft by a left superposition gear and with the right output shaft by a right superposition gear, a double planetary gear set, which exhibits an internal geared wheel, which is mounted on the basket, as well as radially outer planet gears, which mesh with the internal geared wheel, radially inner planet gears, which mesh with the radially outer planet gears and with a gearwheel, which is connected to a first of the two output shafts, and a planet carrier, on which the radially inner and the radially outer planet gears are mounted. The planet carrier can be coupled with the second of the two output shafts by way of a clutch.
