Abstract

The air spring has a cylindrical bellows fixed on supports (6,7) and connected by a pipe to a pressurised gas reservoir. The connection for the pipe is inside the side area of the bellows approximately in the centre. The pipe connection can be made of metal or plastics and can be fixed by screwing, pressing or vulcanisation. The bellows can have a tensile belt containing the connection. USE/ADVANTAGE - Space saving connection of feed pipe for air spring.d

Description

Die Erfindung betrifft eine Luftfeder gemäß Oberbegriff des Anspruchs 1.The invention relates to an air spring according to the preamble of Claim 1.

Über Luftfedern ist unter den verschiedensten Gesichtspunkten bereits vielfach berichtet worden, wobei die DE-A 29 04 521, die DE-A 29 05 791 und DE-A 36 43 073 hier als Stand der Technik stellvertretend genannt werden.Air springs is among the most varied Aspects have already been reported many times, whereby DE-A 29 04 521, DE-A 29 05 791 and DE-A 36 43 073 are mentioned here as prior art.

Bislang war der Anschluß der Leitung zu einem Druckgasreservoir innerhalb des Abstützelementes angeordnet. Mit dem erfindungsgemäßen Anschluß innerhalb des Seitenbereiches des Balges wird nun aus platzsparenden Gründen ein völlig neuer Weg in der Luftfedertechnologie beschritten.So far, the line was connected to one Compressed gas reservoir arranged within the support element. With the connection according to the invention within the Side area of the bellows is now made of space-saving Founding a completely new path in air spring technology followed.

Die Erfindung wird nun anhand von Ausführungsbeispielen (A bis D) unter Bezugnahme auf schematische Zeichnungen erläutert.The invention is now based on exemplary embodiments (A to D) with reference to schematic drawings explained.

  • A) Die Luftfeder (1) weist einen zylindrischen Balg (2) auf, wobei sich innerhalb des mittigen Seitenbereiches der Anschluß (3) befindet. Der Balg selbst ist mittels Wulstkernen (4, 5) an den Stützelementen (6, 7) befestigt - Fig. 1.A) The air spring ( 1 ) has a cylindrical bellows ( 2 ), the connection ( 3 ) being located within the central side region. The bellows itself is attached to the support elements ( 6 , 7 ) by means of bead cores ( 4 , 5 ) - FIG. 1.
  • B) Die Luftfeder (8) weist ebenfalls einen zylindrischen Balg (9) auf, wobei dieser mit einer zusätzlichen Metallglocke (10) ausgerüstet ist, die eine Öffnung für den Anschluß (11) besitzt - Fig. 2. B) The air spring ( 8 ) also has a cylindrical bellows ( 9 ), which is equipped with an additional metal bell ( 10 ) which has an opening for the connection ( 11 ) - Fig. 2nd
  • C) Die Luftfeder (12) weist einen Balg (13) auf, der als Halbrollbalg ausgebildet und mit einem seitlichen Anschluß (14) versehen ist - Fig. 3.C) The air spring ( 12 ) has a bellows ( 13 ) which is designed as a half-roll bellows and is provided with a side connection ( 14 ) - FIG. 3.
  • D) Der Balg einer Luftfeder ist gemäß DE-A 29 04 521 mit einem zugfesten Gürtel ausgerüstet, in dessen Bereich der Anschluß angeordnet ist.D) The bellows of an air spring is in accordance with DE-A 29 04 521 equipped with a tensile belt in its area the connection is arranged.
