1. A drive unit for an electrically operated vehicle axle of a two-track vehicle, the drive unit comprising an electric machine that drives vehicle wheels via a gearbox, the gearbox comprising a gear stage and an axle differential, wherein:
the electric machine is arranged transversely in the vehicle axle;
a stator housing of the electric machine is axially extended in a vehicle transverse direction with a gearbox housing;
the drive unit is supported in a three-point bearing via three unit bearings in a vehicle body of the vehicle, wherein, for a torque support of reaction forces, the three unit bearings of the three-point bearing include two gearbox-side unit bearings, via which the gearbox housing is supported in the vehicle body;
the gearbox housing is composed of two housing parts which are arranged axially one behind the other in the vehicle transverse direction, the two housing parts being an intermediate housing flanged to the stator housing and a housing cover which closes the gearbox housing interior, wherein the housing cover and the intermediate housing each have bearing walls which are axially opposite one another, wherein gearbox shafts and flange shafts are rotatably mounted in the bearing walls of the housing cover and the intermediate housing;
a first gearbox-side unit bearing of the two gearbox-side unit bearings is formed on the housing cover, and a second gearbox-side unit bearing of the two gearbox-side unit bearings is formed on the intermediate housing;
each of the three unit bearings is designed as a rubber-metal sleeve bearing which is pressed into a mounting eye of the gearbox housing or the stator housing;
the first gearbox-side unit bearing lies in a bearing wall plane of the housing cover; and
the second gearbox-side unit bearing lies in a bearing wall plane of the intermediate housing.
