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.

A brush holder for holding at least two brushes for a sliding contact arrangement, including an intermediate element and two contact elements for electrically contacting at least one of the brushes, the contact elements being arranged on two opposite sides of the intermediate element and the intermediate element having a receptacle extending through the opposite sides for a rotating shaft.
