Patent number: 12071171Abstract: A coupling element for fitting to a threaded spindle. The coupling element has a receiving portion which is formed integrally with a coupling portion. The receiving portion extends in a hollow-cylindrical manner along an axis having an axial receiving opening for receiving the threaded spindle, and the coupling portion is flattened transversely with respect to the axis relative to the receiving portion and has a connection means. In order to be able to produce a coupling element in a more efficient and flexible manner, the receiving portion and the coupling portion be formed from a continuous integral pipe portion, wherein the coupling portion has a pressing portion in which the pipe portion is plastically compressed flat transversely relative to the axis.Type: GrantFiled: June 18, 2019Date of Patent: August 27, 2024Assignees: thyssenkrupp Presta AG, thyssenkrupp AGInventors: Sebastian Huber, Jean-Pierre Specht

Patent number: 11702124Abstract: A motor adjustment drive for a vehicle steering column includes a threaded spindle with an axis. The threaded spindle engages a spindle nut. A drive unit and a gear wheel which is connected to the spindle nut or the threaded spindle for rotation therewith is driveable to rotate by the drive unit and is rotatably mounted in a bearing housing between two outer bearing rings that are axially supported at the bearing housing. The outer bearing rings each have, on their sides facing one another, a circumferential outer bearing face that is coaxial to the axis. Each outer bearing face lays opposite a bearing face embodied on the end side at the gear wheel. An outer bearing ring is axially resiliently supported at the bearing housing via an elastic element, which exerts an axial force that biases the two outer bearing rings toward each other.Type: GrantFiled: July 9, 2019Date of Patent: July 18, 2023Assignees: THYSSENKRUPP PRESTA AG, THYSSENKRUPP AGInventors: Sebastian Huber, Arne Schacht, Jean-Pierre Specht
