Publication number: 20240092431Abstract: A wheel cover apparatus for a vehicle includes an upper planar section for at least partially covering the wheel outer side of a steerable wheel, a lower planar section for at least partially covering the wheel outer side of the steerable wheel, an adjustment device for adjusting a position and/or orientation of the upper planar section and a positioning device for positioning the lower planar section. The upper planar section can be arranged on a body of a vehicle so as to be pivotable about a first pivot axis extending in the longitudinal direction of the vehicle. The upper planar section and the lower planar section are connected to each other so as to be pivotable about a second pivot axis extending in the longitudinal direction of the vehicle. The upper planar section is coupled to the adjustment device in such a manner that, in a functional installed state in the vehicle, the upper planar section is movable relative to the wheelhouse by means of the adjustment device.Type: ApplicationFiled: May 23, 2022Publication date: March 21, 2024Inventors: Jurij JECMENJAK-URBAN, Andreas MAYER, Ludwig SEETHALER

Patent number: 7650822Abstract: A machining apparatus for making a plasticizing barrel includes a clamping device for securing the plasticizing barrel, with the clamping device constructed for rotation about a rotation axis and for off-center acceptance of the plasticizing barrel to thereby cause the plasticizing barrel to wobble about its symmetry axis, when the clamping device rotates. The clamping device interacts with a machining unit to provide the plasticizing barrel with an internal conical bore for receiving a screw. The machining unit has a turning tool which is movable linearly back-and-forth in a direction of an axis which extends in relation to the rotation axis at an incline of about half a cone angle of the conical bore, wherein the conical bore being produced has a center line which coincides with the rotation axis.Type: GrantFiled: January 19, 2007Date of Patent: January 26, 2010Assignee: KraussMaffei Technologies GmbHInventor: Ludwig Mayer
