A drive device has an internal combustion engine connection configured for receiving driving power from an internal combustion engine and has an electric motor generator configured for outputting driving power to an electric motor generator connection. A coupling device is configured for coupling both the internal combustion engine connection and the electric motor generator connection to at least one power train connection that is configured for outputting driving power to a power train. The coupling device has a radially outer drive part and a coupling portion lying radially within the drive part, which coupling portion is configured for selectively connecting the drive part to the power train connection in a rotationally fixed manner. A power transmission portion is arranged on an outer circumferential surface on the radially outer drive part, which power transmission portion is configured for receiving driving power from the electric motor generator. Both the internal combustion engine connection and the electric motor generator connection are arranged concentrically to a main drive axis. The power transmission portion partially or fully covers the coupling portion in the longitudinal direction of the main drive axis. An electric motor axis, about which an electric motor shaft configured for outputting driving power from the electric motor generator is provided, which electric motor axis is arranged axially parallel to and radially spaced from the main drive axis.

An assembly of a first component designed as an axle or a shaft on a second component, is provided, in particular for a vehicle. The first component is secured to the second component at least in the axial direction of the first component. At least one of the components has at least one first deformation on one side, the deformation being used to secure the first component on the second component in a first direction which coincides with the axial direction. At least one of the components has at least one second deformation on the same side, the second deformation being used to secure the first component on the second component in a second direction which coincides with the axial direction and is opposite the first direction.

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.

The invention relates to a heating device () for a vehicle, comprising: a flow path () for a liquid heat transfer agent; an electric heating device () for generating heat and for releasing generated heat to the heat transfer agent on a heating portion () of the flow path; and an electronic controller () for controlling a heat output of the heating device. The controller () is provided with a heat releasing body in order to release waste heat of the controller () to the heat transfer agent on a preheating portion () of the flow path upstream of the heating portion (). The invention likewise relates to a method for cooling the controller.

A coupling assembly is provided for a transmission assembly, in particular for a multiple spider planetary gear transmission, wherein the transmission assembly has two speed-change gear units coupled to each other. A first shaft and a second shaft are coupleable with one of the speed-change gear units, wherein by blocking of one of the shafts two shifting stages of the transmission assembly are shiftable. A third shaft is provided as well as a first shifting element and a second shifting element, each of which couples the first shaft and the second shaft with the third shaft. A third shifting element is provided which can brake and/or block the third shaft.
