Definitions

  • the invention relates to an air spring arrangement according to the preamble of claim 1.
  • Air spring arrangements of this type are mainly used in automotive engineering.
  • a generic air spring arrangement with air spring cover, air spring piston and air spring bellows with an additional outer guide is described for example in the documents DE-A-3643073 and DE-A-10001 018. If appropriate, the air spring arrangement can also be provided with a vibration damper (shock absorber) and / or with a protective sleeve, reference being made in this regard in particular to the document DE-A-19753 637.
  • the air bellows is usually provided with an embedded reinforcement, in the form of an axial bellows (DE-A-3643073; Fig. 1) or cross-layer bellows (DE-A-2904522; Fig. 2).
  • an axial bellows with its axially extending thread reinforcements
  • the outer guide has been made of a metallic material, in particular an aluminum alloy.
  • the object of the invention is now to provide a more cost-effective alternative to the previously known outer guides, with a simultaneous reduction in weight.
  • Fig. 4 is a fabric in a crossed arrangement.
  • the air spring 1 shows an air spring arrangement 1, the air spring bellows 2 made of elastomeric material enclosing a volume-elastic air chamber 3.
  • the air bellows is usually provided with an embedded reinforcement, in particular in the form of an axial bellows.
  • the air spring cover 4 which is usually pot-shaped and also often serves as a pressure vessel, has a first fastening area 5, to which one end of the air spring bellows 2 is fastened by means of a clamping ring 6.
  • the air spring piston 7 as a tubular component comprises an end region 8 which is arranged opposite the air spring cover 4. This is followed laterally by the second fastening area 9 for the other end of the air bellows 2.
  • the attachment is also carried out here by means of a clamping ring 10, the bellows flanging the clamping ring.
  • This fastening area is usually provided with an undercut to form a shoulder.
  • the outer guide 13 which is fastened to the air spring cover and / or to a component fixed to the body and / or to the air bellows, reference being made, for example, to the publication DE-U-29823508, essentially encloses the entire area of the air bellows 2.
  • Fig. 2 now shows the tubular outer guide 13 made of plastic with high impact strength, preferably based on a polyamide or polyester.
  • the plastic is provided with an embedded reinforcement 14.
  • This reinforcement consists of fibers, especially glass fibers, which are in the plastic can be mixed in.
  • a fabric construction, in particular in the case of a single-layer arrangement, is also possible, two variants being presented below.
  • the fabric 15 is in a warp-weft arrangement, the warp direction A being the axial direction and the weft direction B being the circumferential direction (arrow direction) of the outer guide 13.
  • the fabric 16 has a crossed arrangement.
  • Glass fibers are preferably used as the base material for the fabric 15 and 16.
  • the plastic outer guide with the strength members presented here lead to a reduction in the wall thickness and thus to a weight reduction.
  • Air spring arrangement Air bellows Air chamber Air spring cover (air spring cup, pressure container) first fastening area clamping ring Air spring piston (rolling piston, plunger piston) forehead area second fastening area clamping ring Rolling surface loop (roll fold) External guide Strength support fabric in chain-weft arrangement with warp direction A and weft direction B Fabric in a crossed arrangement
