Abstract

A gear unit for a motor vehicle electric drive system, has a housing with a middle portion and a first and second axial end portions. The middle portion receives an electric machine. A differential gear is arranged in the second end portion of the housing. The differential gear is connected on the drive side to a first planetary gearset and on the driven side to a first output shaft and second output shaft arranged coaxial to one another. The second output shaft is a hollow shaft, and the first output shaft extends into the second output shaft. A first bearing for rotatable support of the second output shaft is arranged radially between the second output shaft and a structural component of the gear unit, and a second bearing for the rotatable support of the two output shafts is arranged between the first output shaft and second output shaft.
