Definitions

  • the invention relates to an outer cylinder according to the preamble of patent claim 1.
  • a vibration damper with an external damping valve device which has two separate damping valves whose respective main axis intersects a longitudinal axis of the vibration damper.
  • the object of the present invention is to realize a vibration damper with an external housing, in which a smaller space requirement exists.
  • the object is achieved in that the housing is mounted rotatably about a transverse axis of the housing to the outer cylinder.
  • a first damping medium connection is arranged concentrically to the transverse axis.
  • the lateral surface has a flat contact surface with the housing.
  • At least one further damping medium connection comprises a distributor space curved around the transverse axis, to which the housing is connected.
  • At least one sleeve is fixed on the contact surface, which fixes the housing to the outer cylinder via a hollow fastening element.
  • the outer cylinder carries an adapter to which the housing is attached.
  • the adapter is fixed on the sleeve, the hollow fastening element on the outer cylinder.
  • the housing has a support flange with a cylinder-side contact surface.
  • the adapter should be as slim as possible and lightweight and has a retaining flange with the contact surface.
  • the retaining flange and the support flange have substantially the same outer contour, so that between the adapter and the housing as needed z.
  • FIG. 1 outer cylinder with housing in a perspective view
  • FIG. 2 shows a sectional view through the outer cylinder with the housing according to FIG. 1
  • FIG. 3 adapter of FIG. 2 as a single part
  • FIG. 4 housing of FIG. 2 as a single part
  • outer cylinder 1 shows an outer cylinder 1 for a vibration damper with an external housing 3.
  • the term outer cylinder 1 does not require that the vibration damper necessarily has an inner cylinder. Rather, any known design of a vibration damper is conceivable.
  • the housing 3 is shown without an assembly. It would be conceivable z.
  • a pump assembly or at least one external damping valve As an external working or storage space, a pump assembly or at least one external damping valve.
  • FIG. 2 shows a sectional view of the outer cylinder 1 in the region of the housing 3.
  • the outer cylinder 1 has at least two radial damping medium connections 5, which are arranged in series.
  • a lateral surface 7 of the outer cylinder 1 has a flat contact surface 9 to the housing 3. This planar contact surface 9 in turn supports an adapter 11, to which the housing 3 is fastened.
  • the adapter 1 1 is shown as a single part.
  • the adapter 1 1 has one of the geometry of the jacket and the contact surface 7; 9 adapted mating surface 13, so that there is a non-rotating connection between the adapter 1 1 and the outer cylinder 1.
  • the adapter 1 1 has a contact surface 15 to a cylinder-side contact surface 17 of the housing 3.
  • the adapter has ter 1 1 via a retaining flange 19 and the housing 3 via a support flange 21st

  • FIG. 3 shows the distributor space 25, which is likewise designed concentrically with a constant radius of curvature in the contact surface 15 of the adapter 11.
  • a sleeve 27 is attached, for. B. welded (Fig.2).
  • This sleeve 27 has an internal thread 29 for receiving a hollow fastening element 31.
  • the sleeve 27 could also be embodied without an internal thread and exert a retaining force by means of a press fit with the hollow fastening element 31 in order to fix the housing 3 to the outer cylinder 1.
  • fastening means 33 can be executed between the carrier flange 21 and the retaining flange 19.
  • a circumferential clamping ring 35 each on the cover pages 37; 39, which are opposite to the contact surfaces 15; 17 on the retaining flange and the support flange are present, supported.
  • the sleeve 27 is mounted on the contact surface 9 of the outer cylinder 1. Thereafter, the adapter 1 1 is placed, which is aligned by the shape of the counter surface 13. In a next assembly step, seals will be gene 41; 43 inserted, which seal the two damping medium connections 5 and the associated flow channels, such as the distribution chamber 25 against each other.
  • the housing 3 can be placed on the adapter 11 and secured by the hollow fastening element 31.
  • the hollow fastening element 31 is biased so far that a tight connection between the outer cylinder 1 and the housing 3 is present.
  • clamping ring 35 is optionally placed.
