Abstract: An air vent is described, having a housing with an air inlet section, a main air channel, and an air outlet section, the main air channel having at least two opposing sections, which reduce the size of the main air channel starting from the air inlet section and starting from the air outlet section. At least two air channels, which lead into the main air channel via outlet openings, are arranged behind the sections. A pivotably mounted flap, which closes the air channel when in a non-actuated position, is located in the region of inlet openings in each of the air channels. In addition, at least one control element on a control member and a drive unit are provided, wherein the flaps can be pivoted via the at least one control element by means of pivot levers. The Coanda effect is used to deflect the air.

Abstract: A crossmember arrangement for reinforcing a motor-vehicle body includes a crossmember for dissipating loads in the Y direction, an intermediate piece, which is connected directly or indirectly to the crossmember and is intended for fastening the crossmember to a supporting pillar, in particular a B pillar, and a fastening body, which is connected to the intermediate piece and is intended for butting with surface-area contact against the supporting pillar. The fastening body is configured in the form of a chamber profile which runs predominantly in the Y direction. Dissipation of high loads in a motor-vehicle body is made possible, along with straightforward installation capability of the crossmember arrangement in the motor-vehicle body, as a result of the fastening body of the crossmember arrangement, the fastening body is configured in the form of a chamber profile, running essentially in the Y direction.

Abstract: A method for compensating for the deflection of a milling cutter during the machining of a workpiece by a numerically controlled machine tool having a plurality of axes includes: executing a learning cut on a test workpiece having a known geometry by the milling cutter mounted on a tool spindle in a climb milling mode, and in doing so, ascertaining a correlation between a quantity that is proportional to the torque of the drive of the tool spindle and the deflection of the milling cutter normal to a surface of the test workpiece, the deflection being determined by comparing the actual contour of the test workpiece to a setpoint contour. This is followed by storing of the correlation for the milling cutter and machining of the workpiece by the milling cutter in a climb milling mode, while utilizing the stored correlation for compensating for the deflection of the milling cutter by applying a positional correction that is proportional to the quantity to a setpoint position of the axes of the machine tool.
Abstract: An electric vehicle, having a floor assembly including lateral longitudinal carriers, front and rear crossmembers, a vehicle undertray which extends between the lateral longitudinal carriers and the crossmembers and a passenger compartment floor which extends above the vehicle undertray, a technical space between the passenger compartment floor and the vehicle undertray in a rear section of the floor assembly, in which rear section rear seats are mounted above the passenger compartment floor. Furthermore, the electric vehicle includes at least one electric machine and a traction battery arranged below the floor assembly and on the floor assembly. Starting from the passenger compartment floor, the rear crossmember extends as far as into the region of the vehicle undertray and closes the technical space at a rear end. The traction battery is mounted on the lateral longitudinal carriers and on the front and rear crossmembers, and is sealed circumferentially.
