Abstract
(DE)
Bei einer bekannten Vorrichtung zur schwingungsdämpfenden Lagerung einer Drucklufterzeugungsanlage ist ein erstes Federelement vorgesehen, das an einem Befestigungsträger befestigt ist. Bei einer selbsttragenden Wagenkastenstruktur in Leichtbauweise hat sich herausgestellt, daß der Isoliergrad des bekannten Federelementes bei wagenkastenseitig konstruktionsbedingten Resonanzen nicht ausreichend ist. Die neue Vorrichtung soll eine gute Schwingungsisolierung ohne Vergrößerung der lateralen und longitudinalen Auslenkung der Aggregate erzielen. Hierzu ist ein zweites Federelement (15, 15', 15'') vorgesehen, an dem die Drucklufterzeugungsanlage (2) angeordnet ist, wobei eines der beiden Federelemente (5, 5', 5'', 15, 15', 15'') in vertikale Richtung eine Federsteifigkeit aufweist, die höchstens halb so groß ist wie seine Federsteifigkeit in horizontale Richtung, und wobei das zweite Federelement (15, 15', 15'') zu dem ersten Federelement (5, 5', 5'') in Reihe geschaltet ist. Mit der erfindungsgemäßen Vorrichtung können am Wagenkastenboden meßbare Beschleunigung auf bis zu 30 % der aus dem Stand der Technik bekannten Werte reduziert werden.

A known device for the vibration-absorbing mounting of a compressed-air generator is provided with a first spring element which is mounted on a mounting support. Self-contained lightweight understructures have shown that the known spring element provides an insufficient degree of insulation at resonances that are caused by the design of the understructure. The aim of the novel device is to provide a good vibration insulation without increasing the lateral and longitudinal deflection the components. To this end, a second spring element (15, 15', 15'') is provided on which the compressed-air generator (2) is arranged. One of the two spring elements (5, 5', 5'', 15, 15', 15'') has a spring rigidity in the vertical direction that is maximally half its spring rigidity in the horizontal direction. The second spring element (15, 15', 15'') is arranged in series relative to the first spring element (5, 5', 5''). The inventive device provides a means for reducing the acceleration measured at the bottom of the understructure to values which are at least 30 % of the values known from the prior art.

Dans un dispositif connu permettant un montage antivibratile d'un générateur d'air comprimé, il est prévu un premier élément ressort fixé sur un support de fixation. Il s'est avéré pour des structures de caisses monocoques légères, que le degré d'isolation de l'élément ressort connu était insuffisant dans le cas de résonances inhérentes à la construction intervenant côté caisse. Selon l'invention, ce nouveau dispositif vise à fournir un meilleur effet antivibratile sans augmenter la déviation latérale et longitudinale des unités. A cet effet, il est prévu un second élément ressort (15, 15', 15'') sur lequel le générateur d'air comprimé (2) est placé. Un des deux éléments ressort (5, 5', 5'', 15, 15', 15'') présente dans le sens vertical, une rigidité atteignant au plus la moitié de celle qu'il a dans le sens horizontal. Le second élément ressort (15, 15', 15'') est monté en série avec le premier élément ressort (5, 5', 5''). Ce dispositif permet de réduire l'accélération mesurable au niveau du fond de la caisse, jusqu'à 30 % des valeurs connues dans l'état de la technique.
