Description
Stand der TechnikState of technology
Die Erfindung betrifft eine niveauregulierbare Luftfederungsvorrichtung für Fahrzeuge, insbesondere für Schienenfahrzeuge gemäß Patentanspruch 1.The The invention relates to a level-adjustable air suspension device for vehicles, especially for Rail vehicles according to claim 1.
Eine solche ist aus dem Stand der Technik, beispielsweise aus dem „Kraftfahrtechnischen Handbuch", Robert Bosch GmbH, 22. Auflage, Springer-Verlag 1998, Seiten 581 bis 583 bekannt. Die dort beschriebene niveauregulierbare Luftfederungsvorrichtung beinhaltet außer dem Luftbalg eine Druckluftversorgungsanlage zur Lieferung von Druckluft in den Luftbalg mittels einer Luftfederventile beinhaltenden Ventileinrichtung. Die Luftfederventile werden angesteuert, um die Luftmenge in den Luftbälgen derart zu regeln, daß ein Fahrzeugaufbau des Fahrzeugs im wesentlichen stets den gleichen vertikalen Abstand zu den Fahrzeugachsen hat oder um bestimmte Niveaulagen des Fahrzeugaufbaus zu erzielen, wie beispielsweise ein Absenken eines Busaufbaus an Haltestellen als Einstiegserleichterung. Darüber hinaus bilden die Luftbälge Federungselemente der Fahrzeugfederung.A Such is from the prior art, for example from the "Automotive Manual ", Robert Bosch GmbH, 22nd edition, Springer-Verlag 1998, pages 581 to 583 known. The level-adjustable air suspension device described there includes except the air bellows a compressed air supply system for the supply of compressed air in the air bellows by means of an air spring valve-containing valve device. The air spring valves are controlled to reduce the amount of air in the airsleeves in such a way that a Vehicle structure of the vehicle essentially always the same has vertical distance to the vehicle axles or to certain level positions to achieve the vehicle body, such as a lowering a bus structure at stops as an entry-level facilitation. Furthermore form the air bellows Suspension elements of the vehicle suspension.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine niveauregulierbare Luftfederungsvorrichtung der eingangs erwähnten Art derart weiterzubilden, daß sie kostengünstiger herstellbar ist.Of the The present invention is based on the object, a level-controllable Air suspension device of the type mentioned in such a way, that she cost-effective can be produced.
Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale von Patentanspruch 1 gelöst.According to the invention this Task by the characterizing features of claim 1 solved.
Vorteile der ErfindungAdvantages of the invention
Die Federungsfunktion wird wie beim Stand der Technik durch den Luftbalg erfüllt, jedoch ist dieser im wesentlichen hermetisch dicht und wird nur zu Montage- oder Wartungszwecken entleert oder befüllt, um beispielsweise einen durch Diffusion hervorgerufenen Druckverlust auszugleichen. Der Luftbalg ähnelt daher in der Konzeption einem Fahrzeugreifen, bei welchem nur gelegentlich Druckluft oder Druckgas nachgefüllt wird, um einen bestimmten Innendruck aufrecht zu erhalten. Zur Niveauregulierung dient ein bezogen auf den Luftbalg separates Stellglied, welches beispielsweise durch einen Elektromotor betätigt wird. Durch diese Maßnahmen kann die aufwendige Ventileinrichtung samt Verrohrung zum Druckaufbau bzw. Druckabbau im Luftbalg entfallen, was sich positiv auf die Herstellkosten der Luftfederungsvorrichtung auswirkt. Sofern keine weiteren Druckluftverbraucher mehr vorhanden sind, kann die Druckluftversorgung des Fahrzeugs komplett entfallen.The Suspension function is like in the prior art by the air bellows Fulfills, however, this is essentially hermetically sealed and will only emptied or filled for assembly or maintenance purposes For example, caused by diffusion pressure loss compensate. The bellows resembles therefore in the conception of a vehicle tire, in which only occasionally Compressed air or compressed gas refilled is to maintain a certain internal pressure. For level control serves a relative to the air bellows separate actuator, which is actuated for example by an electric motor. Through these measures can the elaborate valve device including piping to build up pressure or pressure reduction in the air bladder omitted, which has a positive effect on the Manufacturing costs of the air suspension device affects. If none more compressed air consumers are more available, the compressed air supply completely eliminated.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Patentanspruch 1 angegebenen Erfindung möglich.By in the subclaims listed activities are advantageous developments and improvements in the claim 1 indicated invention possible.
Gemäß einer besonders bevorzugten Ausführungsform der Erfindung umfaßt der Luftbalg ein Ventil zum gelegentlichen Nachfüllen oder Entleeren, wobei der Luftbalg bei geschlossenem Ventil im wesentlichen hermetisch dicht ist. Das Stellglied kann beispielsweise elektrochemisch, piezoelektrisch, elektromotorisch oder hydraulisch betätigt sein. Besonders bevorzugt wird ein Motor-Spindeltrieb verwendet, bei welchem eine durch den Motor getriebene Spindel sich in eine Spindelmutter einschraubt, um die Länge des Stellglieds zu verändern.According to one particularly preferred embodiment of the invention the bellows a valve for occasional refilling or emptying, wherein the air bellows with the valve closed is substantially hermetic is tight. The actuator may, for example, electrochemical, piezoelectric, electric motor or hydraulically operated be. Particularly preferred is a motor spindle drive is used, in which a driven by the motor spindle in a Screw in the spindle nut to change the length of the actuator.
Vorzugsweise ist eine Steuer- oder Regelungseinrichtung vorgesehen, welche das Stellglied derart steuert oder regelt, daß das Niveau des Fahrzeugaufbaus im wesentlichen unabhängig vom Beladungszustand stets gleich bleibt oder bestimmte gewünschte Lagen einnimmt. In besonders bevorzugter Anwendung kann die Steuer- oder Regelungseinrichtung das Stellglied derart steuern oder regeln, daß eine Niveauänderung aufgrund eines allmählichen Druckverlusts des Luftbalgs, beispielsweise durch Diffusion, automatisch ausgeglichen wird. Hierzu ist ein mit der Steuer- oder Regelungseinrichtung zusammenwirkender Sensor zur Erfassung des Niveaus des Fahrzeugaufbaus vorhanden. Dieser Sensor kann gleichzeitig zur Erfassung der Fahrzeuglast vorgesehen und zu diesem Zweck bereits vorhanden sein, wodurch sich eine vorteilhafte Funktionsvereinigung in einem einzigen Bauteil ergibt.Preferably a control or regulating device is provided which the Actuator controls or regulates such that the level of the vehicle body essentially independent always remains the same from the loading condition or certain desired positions occupies. In a particularly preferred application, the control or Control device to control or regulate the actuator, that one Level change due a gradual loss of pressure the Luftbalgs, for example by diffusion, automatically balanced becomes. For this purpose, a cooperating with the control or regulating device Sensor for detecting the level of the vehicle body available. This sensor can simultaneously be used to detect the vehicle load and already exist for this purpose, resulting in an advantageous Function association in a single component results.
