  • DEVICE FOR PRESSING A RACK AGAINST A PINION, STEERING DEVICE HAVING SUCH A DEVICE, AND METHOD FOR PRODUCING SUCH A DEVICE AND/OR STEERING DEVICE
    Publication number: 20250027554
    Abstract: The disclosure relates to a device for pressing a rack against a pinion, having a thrust piece, having a bearing element, and having a preloading element which acts in the axial direction of a central longitudinal axis of the device, and having a readjustment installation for compensating wear, and having an axial play installation for defining a maximum play of the thrust piece in the axial direction to the central longitudinal axis, the axial play installation being disposed between the readjustment installation and the bearing element, and the axial play installation having an elastic spring element which acts in the axial direction to the central longitudinal axis.

  • Apparatus for pressing a toothed rack against a pinion
    Patent number: 11773947
    Abstract: The disclosure relates to an apparatus for pressing a toothed rack against a pinion, having a pressure piece. The pressure piece can be arranged so as to be displaceable inside a housing and in an axial direction of a centre longitudinal axis. A bearing element that can be fixed on the housing in an axial direction with respect to the centre longitudinal axis, having a prestressing element that acts in an axial direction. Action of the prestressing element arranged between the bearing element and the pressure piece subjected the pressure piece to a prestressing force in an axial direction with respect to the centre longitudinal axis and directed away from the bearing element. A sliding element is arranged on a side, facing away from the prestressing element, of the pressure piece for the purpose of bearing against the toothed rack.
