Publication number: 20240391516Abstract: A steering actuator for a steer-by-wire steering system of a motor vehicle including a rotation stop, which is disposed in the force flow from a drive unit to a steering rod of the wheel module. The rotation stop is formed by a disk assembly and a cooperation of an engagement contour with a locking pin. The rotation stop can be arranged in such a way that installation space is saved, since the rotation stop requires only an axial installation space in the region of the wheel module, but no radial installation space.Type: ApplicationFiled: August 29, 2022Publication date: November 28, 2024Inventors: Andreas WOELLNER, Lukas HOLLER

Publication number: 20180335089Abstract: A strut bearing, including: an axis of rotation; cap; a body portion; and a bearing fixed to the strut bearing cap and to the body portion. The cap includes: a first radial surface facing in a first axial direction; a plurality of ribs; a plurality of spaces, each space circumferentially disposed between a respective pair of ribs; and a plurality of radial recess surfaces. Each rib includes: a radial rib surface extending radially outwardly from the first radial surface; and a slant surface extending from the radial rib surface partly radially outwardly and partly in a second axial direction, opposite the first axial direction. Each radial recess surface: faces in the first axial direction; is circumferentially disposed between two respective ribs; and is off-set, in the second axial direction, from the first radial surface.Type: ApplicationFiled: May 16, 2017Publication date: November 22, 2018Applicant: Schaeffler Technologies AG & Co. KGInventors: Shakeel Shaikh, Alaa Makke, Andreas Woellner, Gerhard Meyer

Patent number: 8992094Abstract: A suspension strut bearing including a guide ring arranged along a suspension strut axis, and a cap. The guide ring is configured for mounting a coil spring, and the cap is configured for supporting the suspension strut bearing on an undercarriage of an automotive vehicle. The guide ring includes a radial flange and further includes a guide nozzle adjoining the radial flange, the guide nozzle serving to guide said coil spring, the suspension strut bearing further including a thrust bearing arranged between the radial flange of the guide ring and the cap. The guide ring includes a reinforcement ring spray coated with a plastic, which reinforcement ring further includes a bushing section for reinforcing the guide nozzle and an integrally formed adjoining radial collar for reinforcing the radial flange, wherein the reinforcement ring is configured as a bearing part of the thrust bearing.Type: GrantFiled: July 16, 2013Date of Patent: March 31, 2015Assignee: Schaeffler Technologies AG & Co. KGInventors: Ralf Stautner, Andreas Woellner, Rainer Lutz

Patent number: 8894295Abstract: A suspension strut bearing includes a guide ring, a cap, and a thrust bearing for an axial mounting of the guide ring on the cap. The plastic guide ring is reinforced with a reinforcement ring including a radial flange, an axial guide nozzle adjoining the radial flange, a bushing section for reinforcing the guide nozzle and an integrally formed radial collar adjoining the guide nozzle for reinforcing the radial flange. A sliding seal is made out of a softer plastic and sprayed onto the radial flange of the guide ring, a sealing lip of the sliding seal being arranged around the guide ring and bearing against a peripheral surface of the cap, the radial collar of the reinforcement ring forming an integrally configured raceway of the thrust bearing. The radial collar includes recesses arranged spaced along a periphery of the radial collar, through which recesses the softer plastic penetrates.Type: GrantFiled: July 16, 2013Date of Patent: November 25, 2014Assignee: Schaeffler Technologies AG & Co.
