Patent number: 11970023Abstract: A vehicle wheel arrangement includes a wheel with a wheel hub and a carrier element for mounting the wheel on a vehicle part and/or for arrangement of a power-transmitting unit. In a joined state of the vehicle wheel arrangement a joining portion of the wheel hub corresponds with a joining portion of the carrier element. In the joined state of the vehicle wheel arrangement, the wheel hub and the carrier element are connected to one another in form-fitting fashion at least in a circumferential direction of a wheel hub axis. The wheel hub includes, in a region of the joining portion, one or more fiber plies with fibers arranged unidirectionally in the circumferential direction of the wheel hub axis. Furthermore, a method can be used to produce a vehicle wheel arrangement having a wheel hub made of fiber-reinforced composite and a carrier element.Type: GrantFiled: November 12, 2018Date of Patent: April 30, 2024Assignee: ACTION COMPOSITES GMBHInventors: Jens Werner, Michael Dressler, Florian Franke, Christian Köhler, Michael Franke, Sandro Mäke, André Bartsch

Patent number: 10953913Abstract: An electromechanical power steering system having an electric servo motor having a motor shaft. The electric servo motor drives a shaft which meshes with a helical wheel. The shaft is rotatably supported in a gear mechanism housing. The motor shaft is coupled to the shaft in a rotationally secure manner by a coupling which compensates for an axial offset. The shaft at the end thereof close to the motor is supported in a bearing in the gear mechanism housing so as to be able to be rotated about a rotation axis and is pivotably supported about a pivot axis which is perpendicular to the rotation axis in such a manner that the pivot axis is arranged in the region of the coupling.Type: GrantFiled: May 17, 2017Date of Patent: March 23, 2021Assignees: thyssenkrupp Presta AG, thyssenkrupp AGInventors: Felix Vonier, Christian Kohler, Eugen Lass

Patent number: 10265892Abstract: A mold system for a resin transfer molding process is presented, in which a cavity of a workpiece (1) to be produced is fully enclosed circumferentially by a multi-part shaping mold (2). The shaping mold (2) is enclosed in a sealed manner by an outer, two or more part enveloping mold (7, 8). A method for consolidating a fiber composite component with this mold system and a method for producing a fiber composite component on the basis of the RTM process is provided, in which the intermediate space between a shaping mold (2) and a surrounding enveloping mold (7, 8) is filled with resin during the resin injection.
