Abstract
Description
Die
Erfindung betrifft eine Luftfeder für eine Fahrzeug-Achse,
mit einer zwischen dem Fahrzeug-Fahrgestell und einem Fahrzeug-Achsenbauteil
angeordneten Rollbalg-Abrollkolben-Kombination, umfassend:
einen
an der Unterseite des Fahrzeug-Fahrgestells befestigten Rollbalg
mit einem stülpbaren Rollbalg-Mantel, einen mit dem unteren
Rand des Rollbalg-Mantels verbundenen und in das Volumen des Rollbalgs
ein- und ausfahrbaren Abrollkolben, und
ein Fahrzeug-Achsenbauteil,
auf dem im Fahrzustand eine Rollbalg-Abrollkolben-Kombination positioniert
aufliegt und beispielsweise bei unbelastetem Zustand des Rollbalgs
sich aus dieser Position lösen kann.The invention relates to an air spring for a vehicle axle, comprising a rolling bellows rolling piston combination arranged between the vehicle chassis and a vehicle axle component, comprising:
a mounted on the underside of the vehicle chassis rolling bellows with a slip-roll sleeve, a connected to the lower edge of the rolling bellows shell and in the volume of the rolling bellows and retractable rolling piston, and
a vehicle axle component on which a rolling bellows rolling piston combination positioned in the driving state and, for example, in the unloaded state of the rolling bellows can be released from this position.
Eine
solche Luftfeder ist aus der
Es stellt sich die Aufgabe, eine konstruktiv einfache Zuordnung des Abrollkolbens bei der Positionierung zu ermöglichen.It the task arises, a structurally simple assignment of To allow rolling piston in the positioning.
Diese Aufgabe wird bei einer Luftfeder der eingangs genannten Art dadurch gelöst, dass auf dem Fahrzeug-Achsenbauteil an der dem Rollbalg zugewandten Seite ein die Außenseite des Abrollkolbens wenigstens teilweise umgreifendes Zentriernest angeordnet ist, in das der Abrollkolben beim Absenken positioniert einrückbar und aus dem dieser beim Aufsteigen aushebbar ist.These Task is characterized by an air spring of the type mentioned solved that on the vehicle axle component at the Rolling bellows side facing the outside of the rolling piston at least partially encompassing centering is arranged in that the rolling piston positioned when lowering positioned engageable and from which this can be removed when ascending.
Demnach liegt im Fahrzustand der Abrollkolben auf dem Fahrzeug-Achsenbauteil auf, löst sich aber bei Anheben des Fahrzeugs von dem Achsenbauteil, so dass das Gewicht der Fahrzeugachse nicht mehr am Abrollkolben zieht.Therefore lies in the driving state of the rolling piston on the vehicle axle component but detaches itself from the axle component when the vehicle is lifted, so that the weight of the vehicle axle is no longer on the rolling piston draws.
Wie an sich aus dem Stand der Technik bekannt, kann mit der Unterseite des Fahrzeug-Fahrgestells ein Deckel fest verbunden sein und der Rollbalg an der Unterseite des Deckels befestigt sein. Eine Verbindung mit dem Fahrgestell kann jedoch auch auf andere Weise geschehen, beispielsweise mit einem mit einem Träger einstückig verbundene Flanschteller.As As known in the art, may be with the bottom the vehicle chassis, a lid be firmly connected and the Bellows be attached to the bottom of the lid. A connection however, the chassis can also be done in other ways, for example, one with a carrier in one piece connected flange plates.
Mit der Luftfeder gemäß Erfindung kann zusätzlich die Aufgabe gelöst werden, das federnde Volumen zu erhöhen.With the air spring according to the invention may additionally the task to be solved, to increase the resilient volume.
Hierzu wird eine Luftfeder verwendet, bei der der Abrollkolben geschlossen ist, so dass das federnde Volumen des Rollbalgs wenigstens teilweise um das Volumen des Abrollkolbens vergrößert ist.For this an air spring is used in which the rolling piston is closed is, so that the resilient volume of the rolling bellows at least partially is increased by the volume of the rolling piston.
Unter dem Begriff »Zentriernest« sollen alle Gebilde verstanden werden, die dazu geeignet sind, dass bei Absenken des Abrollkolbens dieser an seiner Außenseite erfasst wird und auf eine bestimmte Stelle der Achse einrückt.Under The term "centering test" is intended to mean all structures be understood that are suitable for lowering the Rolling piston this is detected on its outside and on a certain point of the axis.
Ein solches Zentriernest kann aus mehreren, vorzugsweise drei, die Unterseite des Abrollkolbens umgreifenden Fingern oder Kragenteilen bestehen. Vorzugsweise weisen die Finger oder Kragenteile in Richtung des Abrollkolbens konkave Krümmungen auf.One such Zentriernest can from several, preferably three, the bottom consist of the rolling piston encompassing fingers or Kragenteilen. Preferably point the fingers or collar parts in the direction of the rolling piston concave curvatures on.
Das Zentriernest kann auch als Auffangschale ausgebildet sein.The Centering test can also be designed as a collecting tray.
Insbesondere, wenn der Boden des Abrollkolbens geschlossen ist, sollte dieser eine Konvexität aufweisen, die der aufgespannten Krümmung des Zentriernestes entspricht. Umgekehrt kann der Boden auch eine konkave Bogenkontur, vorzugsweise in zylindrischer Form, besitzen, die der Außenkontur des jeweiligen Achsenbauteiles entspricht.Especially, if the bottom of the rolling piston is closed, this should be have a convexity, the tensioned curvature corresponds to the Zentriernestes. Conversely, the ground can also be a have a concave arc contour, preferably in a cylindrical shape, which corresponds to the outer contour of the respective axle component.
Als konstruktives Anpassungserfordernis soll hervorgehoben werden, dass das Volumen des Rollbalgmantels in Relation zum Volumen des Abrollkolbens bei Einfahren in den Rollbalg so bemessen ist, dass der untere Teil der Schleppzone des Rollbalgmantels nicht zwischen das Zent riernestes und der Außenseite und/oder den Boden des Abrollkolbens geraten kann.When constructive adaptation requirement should be emphasized that the volume of the bellows shroud in relation to the volume of the rolling piston when retracting into the rolling bellows is dimensioned so that the lower part The drag zone of Rollbalgmantels not between the Zent riernestes and the outside and / or bottom of the rolling piston can.
