Abstract: A drive device for an electrified vehicle axle of a vehicle, including an electric machine, which acts via a transmission on flange shafts which are guided to vehicle wheels, and a cooling/lubrication module, which provides the electric machine and/or the transmission with coolant/lubricant. The drive device has a modular housing design in which a module housing of the cooling/lubricating module, a stator housing of the electric machine and a transmission housing are joined together as separate cast metal parts, in particular diecast parts, to form a unit.

Abstract: An electric drive machine, having a rotor which is arranged on a rotor shaft rotatable about a rotor axis, a stator which surrounds the rotor radially on the outside, a housing which surrounds the stator radially on the outside, and a drive shaft which is arranged rotatably about a shaft axis in a shaft tunnel. The rotor shaft acts, on a first axial end side, which is covered by a first housing part, on the drive shaft via a gear and the rotor shaft is covered on a second axial end side with a second housing part. The first housing part forms a first cavity on the first end side and the second housing part forms a second cavity on the second end side. The first and second cavities are respectively in fluid-conducting connection with the shaft tunnel.

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.

Abstract: 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.

Abstract: 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.

Abstract: A coolant supply system for an electric machine, in which a free electric machine space is provided in the axial direction between the rotor/stator arrangement and an electric machine housing wall, to which coolant can be applied, in particular for stator cooling. The electric machine has a rotor shaft bearing arrangement in which the rotor shaft is rotatably mounted in a hub section of the electric machine housing wall via a rotary bearing. The bearing opening is sealed to the outside of the housing using a sealing element, with the formation of a free space between the rotary bearing and the sealing element. The electric machine housing wall has a coolant connection, via which coolant can be guided from the electric machine space into the free space.

Abstract: A drive device for a vehicle axle of a vehicle, having an electric machine (EM) which outputs to output shafts via a gearbox. The output shafts each lead to a vehicle wheel, wherein a cylindrical stator housing of the electric machine (EM) is elongated in the axial direction by a gearbox housing. In an example, at least one screw point between a stator housing and a gearbox housing has a threaded bolt, which is guided through a non-threaded screw hole of the gearbox housing and is in threaded engagement with an internally threaded bore formed on the stator housing.

Abstract: 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.
