The examples relate to a drive device for an electrified vehicle axle of a vehicle, with an electric machine which outputs via a transmission to drive shafts which lead to vehicle wheels of the vehicle axle, and with a coolant and/or lubricant module which supplies the electric machine and/or the transmission with coolant and/or lubricant. The electric machine, the transmission and the module being joined together to form an structural unit, in which the electric machine and the coolant/lubricant module may be flange-connected to the transmission in a manner to be spaced apart axially from one another, and, on its side which lies axially opposite the transmission. The electric machine having a radially protruding cantilever which bridges an axial spacing (Δx) from the coolant/lubricant module and which, at its free cantilever end, is attached in a force-transmitting manner via at least one bolt location (A) to the coolant/lubricant module, for example, to reduce operationally induced vibrations in the structural unit. In an example, at the cantilever end, a stop element may be provided with an adjustable stroke between a non-use position (N) and a supporting position (S). Before the bolt location (A) is tensioned fixedly, the stroke of the stop element can be adjusted, using up a tolerance gap, until in contact with the module supporting face, with the result that the cantilever end and the module can be braced to one another in a manner which is free from tolerance-induced component deformations.

Drive device for an electrified vehicle axle

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 coolant supply system for a drive device of an electrically operated vehicle axle with an electric machine which has a cylindrical stator housing, in which there is a winding head space axially on both sides of a rotor/stator arrangement, at the bottom of which coolant collects. The two winding head spaces are fluidly connected to one another via a coolant sump, and the stator housing height and the coolant sump height in the electric machine vertical direction add up to a total height. In order to reduce the total height, the coolant sump is offset by a transverse offset from a rotor axis vertical plane. In this way, the stator housing height and the coolant sump height can at least partially overlap in the vertical direction of the electric machine by an overlap amount.

Coolant supply system for an electrically operated vehicle axle

A coolant supply system for a drive device of an electrically operated vehicle axle of a two-track vehicle with an electric machine. The coolant supply system has an electric machine hydraulic circuit in which a coolant tank, the interior of a cylindrical stator housing and a stator housing sump are integrated, in which the coolant draining from the stator housing collects, which can be returned from there to the coolant tank by at least one return pump. The stator housing sump has a suction point on each of its axially opposite axial sides, from which the coolant can be sucked off by the return pump.
