Abstract
A drive device for an electrically operated vehicle axle of a two-track vehicle, with a drive unit in which an electric machine drives vehicle wheels via a gearbox. The electric machine is arranged transversely in the vehicle axle, and a stator housing of the electric machine is axially extended in the vehicle transverse direction with a gearbox housing. The drive unit is supported in a three-point bearing via three unit bearings in the vehicle body. The three-point bearing has two gearbox-side unit bearings via which the gearbox housing is supported in the vehicle body.

A drive device for an electrically operated vehicle axle of a two-track vehicle, with a drive unit in which an electric machine drives vehicle wheels via a gearbox, wherein the electric machine is arranged transversely in the vehicle axle, wherein a stator housing of the electric machine is axially extended in the vehicle transverse direction with a gearbox housing, and wherein the drive unit is supported in a three-point bearing via three unit bearings in the vehicle body, wherein, for a torque support of reaction forces, the three-point bearing has two gearbox-side unit bearings, via which the gearbox housing is supported in the vehicle body, wherein the gearbox housing is composed of two housing parts which are arranged axially one behind the other in the vehicle transverse direction, namely from 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, wherein the first gearbox-side unit bearing is formed on the housing cover, and wherein the second gearbox-side unit bearing is formed on the intermediate housing, wherein each of the unit bearings is designed as a rubber-metal sleeve bearing which is pressed into a mounting eye of the gear housing and/or the stator housing, in that the first gearbox-side unit bearing lies in a bearing wall plane of the housing cover, and/or in that the second gearbox-side unit bearing lies in a bearing wall plane of the intermediate housing.
