Abstract
Description
Die Erfindung betrifft eine Luftfeder der Art nach Anspruch 1.The invention relates to an air spring of the type according to claim 1.
Im Kraftfahrzeugbau ist die Verwendung von Luftfedern allgemein bekannt. Diese Luftfedern arbeiten mit einem luftgefüllten Balg, der zwischen einem ersten und einem zweiten Aufnahmeelement angeordnet ist. Bei den bekannten Luftfedern ist es nicht möglich, neben den axialen Kräften – in Verbindungsrichtung der beiden Aufnahmeelemente – auch radiale Kräfte zu übertragen. Bekannt ist die Verwendung von Luftfederelementen zur Achsfederung. Die Achse wird über Lenker geführt, erfährt durch diese Lenker ihre Beweglichkeit, radiale Kräfte werden über die Lenker abgeführt. Das Luftfederelement wird nur noch axial belastet.In automotive engineering, the use of air springs is well known. These air springs work with an air-filled bellows, which is arranged between a first and a second receiving element. In the known air springs, it is not possible, in addition to the axial forces - in the direction of connection of the two receiving elements - to transmit radial forces. It is known to use air spring elements for axle suspension. The axle is guided by handlebars, experiences their mobility through these links, radial forces are dissipated via the handlebars. The air spring element is only loaded axially.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine Luftfeder in gegenüber den bekannten Lösungen verbesserter Ausführung vorzuschlagen. The object of the present invention is to propose an air spring in relation to the known solutions of improved design.
Diese Aufgabe wird gelöst durch die Merkmale des Hauptanspruches. Weiterbildungen ergeben sich aus den Unteransprüchen.This object is solved by the features of the main claim. Further developments emerge from the subclaims.
Die erfindungsgemäße Lösung besteht aus einer Luftfeder mit einem ersten und einem zweiten Aufnahmeelement, wobei diese Aufnahmeelemente in axialer Richtung sowie senkrecht dazu beweglich sind, mit einem zwischen dem ersten und dem zweiten Aufnahmeelement angeordneten luftgefüllten Balg, wobei der Balg zwischen einer Aufnahme des ersten Aufnahmeelements und einem den Balg umgebenden Aufnahmekörper des zweiten Aufnahmeelementes angeordnet ist. The solution according to the invention consists of an air spring with a first and a second receiving element, wherein these receiving elements are movable in the axial direction and perpendicular thereto, with an arranged between the first and the second receiving element air-filled bellows, wherein the bellows between a receptacle of the first receiving element and a receiving body surrounding the bellows of the second receiving element is arranged.
Der zweite Aufnahmekörper ist als ein einseitig offener Körper in Form eines Topfes, eines Bechers, einer Glocke gestaltet. Der zweite Aufnahmekörper nimmt den auf dem ersten Aufnahmeelement sitzenden Balg im Wesentlichen vollständig auf. Der Balg kann so zwischen der Aufnahme des ersten Aufnahmeelementes und dem Aufnahmekörper des zweiten Aufnahmeelementes in axialer Richtung rollend arbeiten – durch den ihn umgebenden Aufnahmekörper sowie dem Sitz auf der ersten Aufnahme kann der Balg auch Kräfte aufnehmen, die senkrecht zur axialen Richtung, also radial wirken.The second receiving body is designed as a one-sided open body in the form of a pot, a cup, a bell. The second receiving body receives the seated on the first receiving element bellows substantially completely. The bellows can thus roll between the receptacle of the first receiving element and the receiving body of the second receiving element in the axial direction - by the surrounding receiving body and the seat on the first recording of the bellows can also absorb forces acting perpendicular to the axial direction, ie radially ,
Die Öffnung des Körpers ist dem ersten Aufnahmeelement zugewandt. Der Aufnahmekörper sitzt den Balg umgebend auf diesem auf. Der Balg zentriert somit den Aufnahmekörper.The opening of the body faces the first receiving element. The receiving body sits on the bellows surrounding this on. The bellows thus centered the receiving body.
Der Balg sitzt zwischen einer als Führung dienenden Aufnahme des ersten Aufnahmeelementes und der Innenseite des ihn auf- und umgebenden Körpers des zweiten Aufnahmeelementes. Der Balg rollt sowohl an der Führung sowie der Innenseite des Körpers.The bellows sits between serving as a guide receiving the first receiving element and the inside of him up and surrounding body of the second receiving element. The bellows rolls both on the guide and the inside of the body.
Der Balg ist durch den ihn umgebenden Aufnahmekörper nach Art einer Rohrführung geführt. Dadurch kann die Luftfeder sowohl axiale als auch radiale Kräfte übertragen.The bellows is guided by the surrounding receiving body in the manner of a pipe guide. As a result, the air spring can transmit both axial and radial forces.
Der der als Reifen ausgebildete Balg ist mit seinen Ringen am ersten Aufnahmeelement fixiert und gedichtet. Dieses Aufnahmeelement kann bevorzugt als ein zylinderförmiger Körper, als stehender Kolben oder ein Stempel ausgebildet sein, auf dessen Außenumfang der Balg sitzt und an dessen Außenseite der Balg abrollt.The trained as a tire bellows is fixed with his rings on the first receiving element and sealed. This receiving element may preferably be formed as a cylindrical body, as a stationary piston or a punch, on the outer circumference of the bellows sits and rolls on the outside of the bellows.
Das obere Aufnahmeelement ist topfförmig ausgebildet und mit seiner Öffnung über den den Kolben umgebenden Balg gestülpt. Der Balg kann an der Innenseite des ihn umgebenden Topfes mittels eines Ringes fixiert sein. Der Ring kann seinerseits ein elastisches Dämpfungselement aufweisen, um einen Kontakt mit dem Kolben elastisch abzufangen. Durch den beschriebenen Aufbau, dadurch, dass das zweite Aufnahmeelement den Balg in seinem Arbeitsbereich vollständig bzw. im Wesentlichen vollständig umgibt, nimmt der Balg auch radiale Kräfte auf, überträgt diese.The upper receiving element is cup-shaped and slipped with its opening over the surrounding the piston bellows. The bellows can be fixed to the inside of the surrounding pot by means of a ring. The ring may in turn comprise an elastic damping element to intercept a contact with the piston elastic. As a result of the construction described, in that the second receiving element completely or substantially completely surrounds the bellows in its working area, the bellows absorbs radial forces and transmits them.
Bevorzugt kann der Balg auch an dem oberen Ende eines stempel- bzw. kolbenförmigen Körpers des ersten Aufnahmeelementes sitzen. Das zweite Aufnahmeelement ist topfförmig ausgebildet und über den Balg gestülpt, nimmt diesen so vollständig auf. Die radiale Kraftaufnahme ergibt sich in diesem Fall durch das Abrollen des unteren Balgbereiches am Stempel. Preferably, the bellows can also sit at the upper end of a stamp or piston-shaped body of the first receiving element. The second receiving element is cup-shaped and slipped over the bellows, this takes so completely on. The radial force absorption results in this case by the rolling of the lower bellows area on the punch.
Eine weitere Ausführung sieht ein erstes Aufnahmeelement mit einer konisch geformten Balgaufnahme vor. Der den konischen, kegelförmigen Aufnahmekörper, den Konus umgebende Balg kann entsprechend seiner Dimensionierung ein Stück auf auf dessen Außenseite abrollen. Über den auf dem Konus sitzenden Balg ist ein konisch geformter, glockenförmiger Aufnahmekörper des oberen Aufnahmeelementes gestülpt. Die Fixierung des Balges erfolgt über eine Verdickung an seiner Außenseite, welche in einer entsprechenden umlaufenden Nut an der Innenseite des Aufnahmekörpers sitzt.Another embodiment provides a first receiving element with a conically shaped bellows receiver. The conical, conical receiving body surrounding the cone bellows can roll a piece on its outside according to its dimensions. About the seated on the cone bellows, a conically shaped, bell-shaped receiving body of the upper receiving element is slipped. The fixation of the bellows via a thickening on its outer side, which sits in a corresponding circumferential groove on the inside of the receiving body.
Die erfindungsgemäße Luftfeder wird bevorzugt zur Lagerung und Federung einer Fahrerkabine eines Kraftfahrzeuges, eines Lastkraftwagens verwendet. Die Kabine muss nicht durch zusätzliche Lenker zur Aufnahme von in radialer Richtung wirkenden Kräften geführt sein. Das untere, erste Aufnahmeelement ist dabei am Chassis angebracht, das obere, zweite Aufnahmeelement mit der Kabine verbunden. The air spring according to the invention is preferably used for the storage and suspension of a driver's cab of a motor vehicle, a truck. The cab need not be guided by additional links for receiving radially acting forces. The lower, first receiving element is mounted on the chassis, the upper, second receiving element connected to the cabin.
