A traction transmission intermediate shaft is rotatably mounted in the transmission housing. A traction transmission output shaft is rotatably mounted in the transmission housing device, and is arranged axially parallel to and radially spaced apart from the two other traction transmission shafts.

Abstract: Please substitute the new Abstract submitted herewith for the original Abstract: A predetermined breaking body of a shaft of a machine includes a first sub-body, a second sub-body, and a predetermined breaking element. The first and second sub-bodies are connected to one another, so as to conjointly rotate, along a longitudinal center axis of the predetermined breaking body via the predetermined breaking element. The predetermined breaking element is anisotropic, such that during transmission of a torque between the sub-bodies, the predetermined breaking element yields in a first torsion direction under a first predetermined ultimate torsional moment and yields in a second torsion direction opposed to the first torsion direction under a second predetermined ultimate torsional moment. The predetermined ultimate torsional moments differ in size.

Abstract: A lubricant supply for a powertrain in an electrically driven motor vehicle has a hydraulic oil pump, which can be driven by a drive actuator, a lubricant supply point and a lubricant reservoir. The hydraulic oil pump can generate a first lubricant volume flow from the lubricant reservoir to the lubricant supply point and a second lubricant flow volume from the lubricant supply point or an additional lubricant supply point in the lubricant reservoir. The drive actuator is an electric motor. The lubricant supply point is arranged in a traction motor with a rotor shaft and a motor housing. The additional lubricant supply location is disposed in a traction transmission. The lubricant supply points can be supplied with lubricant by way of the first lubricant volume flow.
