Abstract: A ventilation device for transmissions with lubricant comprising water, the device being disposed above the transmission (1) and being connected thereto by way of a line (10) and comprising a pressure equalization opening (13) that leads to the surrounding environment, is to operate without loss of evaporating water to the environment. To this end, the device comprises at least one container (17) designed as a condenser for evaporated water rising through the line (10), the container being provided with a cooling element for dissipating heat (15), the condensate passing from said container (17) back to the transmission (1). In one variant, two containers containing a fluid are described which communicate with one another by way of a U-shaped channel.

Abstract: A roof arrangement for a motor vehicle, and which includes a roof module and a bodywork structure for receiving the roof module. The roof module has a roof outer skin and at least one load-bearing roof bow. The roof bow, on at least one lateral end thereof, includes a tongue extending vertically downward in an installed position. The bodywork structure includes an upwardly open channel in the installed position, the tongue being received in the channel.

Abstract: A method for producing a panelling component for a motor vehicle. The method includes press-forming a fiber-reinforced load-bearing composite component; forming a film having a class-A surface; and joining the load-bearing composite component as a first layer and the film as a second layer via an adhesive as an interposed third layer.

Abstract: A load-bearing structure of a motor vehicle, having hollow profiles and junction elements to connect the hollow profiles. The hollow profiles may be fastened in receptacles of the junction elements, and the junction elements may have a plurality of areal webs in a vehicle vertical direction, at least some of the areal webs forming a framework structure which assists the load path in the respective junction element.
