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.

Drive device for a vehicle axle

A drive device for a vehicle axle of a two-track vehicle having a drive unit having in particular an electric machine, which outputs on the output side on at least one driveshaft leading to a vehicle wheel, which driveshaft is divided into a wheel-side shaft section and an axle-side shaft section which can be coupled to one another or decoupled from one another in a driving manner by means of a formfitting clutch, in order to avoid drag losses in the deactivated drive unit in driving operation with deactivated drive unit.

A rotor for an electrical machine with one or a plurality of cooling ducts through which a cooling agent can flow. One end face of the rotor there is provided an annular space, bounded axially inwardly and radially outwardly and joined communicating with the cooling duct or ducts. A cover plate is provided, attached to the end face and bounding the annular space axially outwardly, having a central through-opening for introducing the cooling agent into the annular space.
