  • Patent number: 11731685
    Abstract: A rack-and-pinion gear is described, which is suitable in particular for a steering system of a motor vehicle. In this a pinion is supported in a pinion housing and meshes with a rack inside this pinion housing. The rack here projects from the pinion housing through at least one housing aperture. A stop ring, which serves to limit a rack longitudinal movement and/or a tilting of the rack, is moreover held in the housing aperture by means of a press fit. In addition, a steering gear having such a rack-and-pinion gear and a steering system for a motor vehicle comprising such a steering gear are described.

  • Patent number: 11485412
    Abstract: A drag link guide assembly for guiding a drag link comprises a slide bushing and a housing enclosing the slide bushing. The housing comprises a socket portion, into which the slide bushing is inserted. The slide bushing comprises a locating area for the drag link having a substantially circular cylindrical periphery with at least one plane torsional locking face. The slide bushing comprises an outward-pointing structure, which interacts with a mating structure that is provided on the internal surface of the housing. A method for producing a drag link guide assembly is furthermore described.
