Description
Die vorliegende Erfindung betrifft ein Luftfederglockesystem für Fahrzeuge mit einer Druckluftkammer, die eine Luftfederglocke und einen Balg umfasst.The present invention relates to a Luftfederglockesystem for vehicles with a compressed air chamber comprising an air spring bell and a bellows.
Die Erfindung betrifft weiterhin die Anwendung des Luftfederglockesystems.The invention further relates to the use of the Luftfederglockesystems.
Bekannte TechnikWell-known technology
Es ist allgemein bekannt, Druckluftkammern anzuwenden, die eine Luftfederglocke und einen Balg umfassen.It is well known to apply compressed air chambers that include an air spring bell and a bellows.
Einer der Nachteile dabei ist, dass variierende Luftdrücke abhängig von den Fahrverhältnissen einen Druck in der Druckluftkammer verursachen können, der die Spezifikationen beeinträchtigt, was zur Folge haben kann, dass die Druckluftkammer bersten kann. Wenn die Luftfederglocke der schwache Punkt der Luftfederglocke ist, werden Fragmente der Glocke folglich zerstreut werden und damit eine öffentliche Gefahr ausmachen.One of the disadvantages of this is that varying air pressures, depending on the driving conditions, can cause pressure in the compressed air chamber that affects the specifications, which can cause the compressed air chamber to rupture. If the air spring bell is the weak point of the air spring bell, fragments of the bell will thus be scattered, thus making a public danger.
Aus der
Aufgabe der ErfindungObject of the invention
Es ist somit die Aufgabe der Erfindung, ein Luftfederglockesystem der eingangs erwähnten Art vorzusehen, das sichert, dass jede Überbelastung keine Zerstreuung von Teilen des Luftfederglockesystems verursacht, das dazu vorgesehen ist, in einer Temperaturspanne von minus 40°C bis zu +80°C zu wirken.It is therefore the object of the invention to provide an air spring bell system of the type mentioned, which ensures that any overload caused no dispersion of parts of the Luftfederglockesystems, which is intended to in a temperature range of minus 40 ° C to + 80 ° C. Act.
Insbesondere in PKW-Werkstätten ist dies im Fokus, da man während einer Reparation schwer verletzt werden kann, wenn der den Druck im System messende gegebene Druckmesser defekt ist. Aber auch im Nahverkehr ist das Problem ein Thema.This is particularly the focus in car repair shops, as it can be seriously injured during a repair if the given pressure gauge measuring the pressure in the system is defective. But also in local transport, the problem is an issue.
Es ist weiterhin die Aufgabe der Erfindung, dass diese Sicherung keine Wartung und periodischen Inspektionen zur Folge hat, was mit Mehrkosten verbunden ist.It is also the object of the invention that this backup has no maintenance and periodic inspections result, which is associated with additional costs.
Beschreibung der ErfindungDescription of the invention
Die oben angeführte Aufgabe wird durch ein Luftfederglockesystem wie im Oberbegriff des Anspruchs 1 beschrieben erfüllt, bei dem die Druckluftkammer einen Sprungdeckel umfasst, wobei der Sprungdeckel ein gegossener und integrierter Teil der Luftfederglocke ist.The above object is achieved by an air spring lock system as described in the preamble of claim 1, wherein the compressed air chamber comprises a jump cover, the jump cover being a cast and integrated part of the air spring bell.
Dies macht es eben möglich, einen gesteuerten Durchbruch der äußeren Konstruktion der Druckluftkammer derart zu sichern, dass für die Umgebungen keine Gefahr vorliegt.This just makes it possible to ensure a controlled breakthrough of the outer construction of the compressed air chamber in such a way that there is no danger for the surroundings.
Dies ermöglicht mehr verschiedene Herstellungsverfahren, bei denen das Integrieren des Sprungdeckels in die Luftfederglocke einerseits die Zahl der Einzelteile nicht vergrößert, während ein gesondert hergestellter Sprungdeckel im Zusammenhang mit den Spezifikationen unterschiedlicher Luftfederglockesysteme vorteilhaft sein kann.This allows for more different manufacturing processes, in which the integration of the jump cover in the air spring bell, on the one hand, does not increase the number of individual parts, while a separately produced jump cover can be advantageous in connection with the specifications of different air spring lock systems.
In einer bevorzugten Ausführungsform gemäß Anspruch 5 kann der Sprungdeckel selbst eine dünnere Wanddicke als die übrige äußere Konstruktion der Luftfederglocke aufweisen, oder wie in einer anderen bevorzugten Ausführungsform gemäß Anspruch 6 eine Reihe von Kerben aufweisen mit hieraus resultierender lokal dünnerer Wanddicke im Verhältnis zur übrigen äußeren Konstruktion der Luftfederglocke.In a preferred embodiment according to
Dies macht es wiederum möglich, bei der physischen Ausformung des Sprungdeckels und damit der Schwächung der Druckluftkammer mehr verschiedene Alternative anzuwenden.This in turn makes it possible to apply more different alternative in the physical formation of the jump cover and thus the weakening of the compressed air chamber.
Vorteilhafterweise kann die Luftfederglocke aus Kunststoff hergestellt ist, vorzugsweise PA6 GF30, und einen Kragen aufweist, auf dem der aus Gummi bestehende Balg befestigbar ist, und wobei ein Teil des Balgs auf eine Platte vulkanisiert ist, die, gemäß einer weiteren Ausführungsform aus Metall hergestellt ist, und in welcher Vorrichtungen für Luftanschluss vorgesehen sein können.Advantageously, the air spring bell is made of plastic, preferably PA6 GF30, and has a collar on which the bellows made of rubber can be fastened, and wherein a part of the bellows is vulcanized on a plate, which is made of metal according to another embodiment , and in which devices may be provided for air connection.
Dies macht es zum ersten möglich, die zwei Hauptkomponenten der Druckluftkammer zu sammeln, von denen die eine die Luftfederglocke aus einem festen Material ist, und von denen die andere der Balg aus einem nachgiebigen Material ist, der also auf eine Metallplatte aufgetragen wird, was zum anderen ermöglicht, dass das Luftfederglockesystem während der beabsichtigten Benutzung am Chassis des Fahrzeugs anliegen kann.This makes it possible for the first to collect the two major components of the compressed air chamber, one of which is the air spring bell of a solid material, and of which the other of the bellows is made of a resilient material, that is applied to a metal plate, resulting in allows the air spring bell system to rest against the chassis of the vehicle during intended use.
Darüber hinaus kann die Luftfederglocke nach einer anderen Ausführungsform äußere Vorrichtungen, eingebettete Buchsen aufweisen, die zur Befestigung der Luftfederglocke gegenüber der Konstruktion vorgesehen ist, in welcher sie wirken soll.In addition, according to another embodiment, the air spring bell may comprise external devices, embedded bushings, provided for attachment of the air spring bell to the construction in which it is intended to act.
Schließlich ist eine Anwendung des Luftfederglockesystems vorgesehen, aus dem hervorgeht, dass das Luftfederglockesystem für Fahrzeuge anwendbar ist.Finally, an application of the Luftfederglockesystems is provided, which shows that the Luftfederglockesystem is applicable to vehicles.
