  • Publication number: 20240391516
    Abstract: 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.

  • Publication number: 20240278773
    Abstract: A vehicle and method for a parking maneuver includes an electrically operated vehicle, having two axles with two drive and chassis modules which are spaced apart by a track width are arranged on each of the axles, and, on the basis of a straight-head position in the longitudinal direction of the vehicle, each of the drive and chassis modules has a separate maximum steering angle with respect to a side of the vehicle and having a control device in which a plurality of steering functions for actuating a steering angle of the drive and chassis modules are configured and stored. A method for carrying out a parking maneuver, in which the drive and chassis modules are adjusted synchronously in accordance with one of the steering functions.

  • Publication number: 20180335089
    Abstract: 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.

  • Patent number: 8992094
    Abstract: 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.

  • Patent number: 8894295
    Abstract: 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.

  • Patent number: 8876399
    Abstract: A suspension strut bearing including a cap (2) and a guide ring (3) mounted for rotation relative to the cap (2) about an axis of rotation (D) and further including at least one seal (10), a thrust bearing (4) being arranged between the cap (2) and the guide ring (3). The cap (2) includes respective centering elements (15, 16) on an inner diameter and on an outer diameter, which centering elements (15, 16) enable an introduction of force into the cap (2).

  • Patent number: 8506171
    Abstract: Spring strut bearing, which has an antifriction bearing that is arranged axially between an upper carrier part and a lower carrier part and a sealing ring. The upper carrier part has two upper rims, and the lower carrier part has two lower rims. The upper rims and the lower rims engage into one another with the result that a combined labyrinth and slip-ring seal is formed.
