Abstract
Description
Die Erfindung betrifft ein Luftfederbein für Kraftfahrzeuge mit karosserieseitiger Lagerung an einem mit Druckausgleichsöffnungen versehenen Domlager, das zwischen einem ersten Luftfederraum und einem zweiten Luftfederraum angeordnet ist. The invention relates to an air spring strut for motor vehicles with body-side mounting on a provided with pressure equalization openings Domlager, which is arranged between a first air spring space and a second air spring space.
Luftfederbeine mit mehreren Kammern sind aus dem Stand der Technik bekannt. Dazu wird z.B. auf die
Aufgabe der Erfindung ist es, ein Luftfederbein für Kraftfahrzeuge zur Verfügung zu stellen, mit dessen Konstruktion auch bei geregelten Dämpfern nur in geringem Umfang bzw. gar kein zusätzlicher Bauraum erforderlich ist unter Beibehaltung des Druckausgleichs zwischen dem eigentlichen Luftfedervolumen und einem zweiten Luftfedervolumen. The object of the invention is to provide an air spring strut for motor vehicles available, with its construction even with controlled dampers only to a small extent or no additional space is required while maintaining the pressure equalization between the actual air spring volume and a second air spring volume.
Zur Lösung dieser Aufgabe ist es nach der Erfindung vorgesehen, das zweite Luftfedervolumen in einem flexiblen Rollbalg zu bilden, der einerseits direkt oder indirekt am Domlager und andererseits an der Kolbenstange befestigt ist. To solve this problem, it is provided according to the invention to form the second air spring volume in a flexible rolling bellows, which is attached on the one hand directly or indirectly on the mandrel bearing and on the other hand to the piston rod.
Der flexible Rollbalg nach der Erfindung kann in vorteilhafter Weitergestaltung einerseits an der Verschlusskappe des Domlagers luft- und druckdicht befestigt, z.B. anvulkanisiert sein. Das andere Ende des Rollbalgs kann auf einer Distanzhülse luft- und druckdicht befestigt, z.B. anvulkanisiert sein, wobei die Distanzhülse auf das freie Endstück der Kolbenstange aufschiebbar und mittels einer Mutter darauf unverschieb- und unverdrehbar festlegbar ist. The flexible rolling bellows according to the invention, in an advantageous further embodiment on the one hand on the cap of the Domlagers air and pressure tight attached, e.g. be vulcanized. The other end of the rolling bellows can be attached to a spacer sleeve in a manner that is air-tight and pressure-tight, e.g. be vulcanized, wherein the spacer sleeve can be pushed onto the free end of the piston rod and by means of a nut on it non-rotatably and non-rotatably fixed.
Die mit einer Domlagerabdichtung nach der Erfindung zu erzielenden Vorteile sind für den Fachmann offensichtlich: der Rollbalg macht im Unterschied zu einer Deckkappe praktisch keinen zusätzlichen Bauraum – weder axial noch radial – erforderlich; er lässt ebenso wie eine flexible Deckkappe Relativbewegungen in Achsrichtung der Kolbenstange wie auch leichte Radialbewegungen (Verkippungen) zu. The achievable with a Domlagerabdichtung according to the invention advantages are obvious to the expert: the rolling bellows makes in contrast to a top cap virtually no additional space - either axially or radially - required; it allows as well as a flexible cover cap relative movements in the axial direction of the piston rod as well as slight radial movements (tilting).
Ein bevorzugtes Ausführungsbeispiel nach der Erfindung ist in der Zeichnung dargestellt. Ferner ist in einer weiteren Figur der Zeichnung eine Lösung nach dem Stand der Technik mit einer luftdichten Deckkappe dargestellt. A preferred embodiment of the invention is shown in the drawing. Furthermore, a solution according to the prior art with an airtight cover cap is shown in a further figure of the drawing.
