Abstract
Description
Die Erfindung bezieht sich auf ein Federbeinstützlager mit einem Lageranschluss zur Anordnung an einer Fahrzeugkarosserie, mit einem ersten Federteller für eine Fahrzeugtragfeder, wobei zwischen dem Lageranschluss und dem ersten Federteller ein Lager angeordnet ist, das ein dem Lageranschluss zugeordnetes Lagereingangsteil und ein dem ersten Federteller zugeordnetes Lagerausgangsteil aufweist, mit einem mit seinem einen Ende an dem Lagerausgangsteil abgestützten Anschlagpuffer aus einem elastischen Werkstoff, der an seinem dem Lagerausgangsteil nahen Endbereich von einem Verstärkungselement umschlossenen und konzentrisch zur Mittelachse eines Federbeins angeordnet ist sowie mit seinem anderen Ende ab einer definierten Einfederungsposition auf einer Stirnfläche eines Zylinders des Federbeins zur Anlage kommt, wobei das Verstärkungselement an dem Anschlagpuffer axial gesichert ist und wobei der Lageranschluss mit dem freien Ende einer Kolbenstange verbunden ist, die in den Zylinder ragt.The invention relates to a strut support bearing with a bearing connection for arrangement on a vehicle body, with a first spring plate for a vehicle suspension spring, wherein between the bearing connection and the first spring plate, a bearing is arranged, which is a bearing connection associated bearing input part and a first spring plate associated bearing output part having a supported at its one end to the bearing output part stop buffer of an elastic material which is arranged at its end near the bearing end part of a reinforcing element and arranged concentrically to the central axis of a strut and with its other end from a defined compression position on an end face of a Cylinder of the strut comes to rest, wherein the reinforcing member is axially secured to the stop buffer and wherein the bearing connection is connected to the free end of a piston rod, which in the cylinder protrudes.
Bei derartigen bekannten Federbeinstützlagern besteht das Problem, dass bei kleinen Abmessungen des Federbeinstützlagers sowie des Federtellers und relativ großen auf den Anschlagpuffer beim Anschlagen an die Stirnseite des Zylinders auftretenden radialen Kräften, der Anschlagpuffer an seinem dem Lagerausgangsteil nahen Endbereich aufplatzen kann.In such known strut support bearings, the problem is that with small dimensions of the strut support bearing and the spring plate and relatively large occurring on the stop buffer when hitting the end face of the cylinder radial forces, the stop buffer can burst at its end near the bearing output part end.
Aufgabe der Erfindung ist es daher ein Federbeinstützlager der eingangs genannten Art zu schaffen, dessen Anschlagpuffer auch bei hohen auf ihn einwirkenden Kräften beim Anschlagen an der Stirnseite des Zylinders gegen Beschädigung insbesondere gegen Aufplatzen geschützt ist.The object of the invention is therefore to provide a strut support bearing of the type mentioned, the bump stop is protected against damage especially against bursting at high forces acting on it when hitting the front of the cylinder.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Verstärkungselement ein den Anschlagpuffer umschließendes Verstärkungsrohr mit einem oder mehreren radial umlaufenden, radial gerichteten Flansche aufweist.This object is achieved in that the reinforcing element has a stop buffer enclosing the reinforcing tube with one or more radially encircling, radially directed flanges.
Das vorzugsweise aus Metall bestehende Verstärkungsrohr besitzt durch den oder die radial gerichteten Flansche eine sehr hohe Festigkeit gegen radiale Verformung, so dass auch hohe radiale Kräfte des Anschlagpuffers nicht zu einem Aufplatzen des Anschlagpuffers in seine Abstützbereich am Lagerausgangsteil führen können.The preferably made of metal reinforcing tube has by the or the radially directed flanges a very high resistance to radial deformation, so that even high radial forces of the stop buffer can not lead to bursting of the stop buffer in its support area on the bearing output part.
Dabei können der oder die Flansche radial umlaufend durchgehend ausgebildet sein.In this case, the flange or flanges may be formed continuously circumferentially radially.
Einfach herstellbar ist es, wenn der oder die Flansche aus radial gerichteten Flanschabschnitten bestehen, wobei radial umlaufend zwischen den Flanschabschnitten Lücken ausgebildet sein können.It is easy to produce if the flange or flanges consist of radially directed flange sections, wherein gaps can be formed radially circumferentially between the flange sections.
Die Flansche können sich von dem Verstärkungsrohr radial nach außen und/oder radial nach innen erstrecken.The flanges may extend radially outwardly and / or radially inwardly from the reinforcing tube.
Hintergreifen der oder die sich radial nach innen erstreckenden Flansche eine radial umlaufende, radial gerichtete Schulter des Anschlagpuffers, so kann der Anschlagpuffer von dem Verstärkungselement in seiner Einbauposition gehalten werden.Behind the radially inwardly extending flanges or a radially encircling radially directed shoulder of the stop buffer, the stop buffer can be held by the reinforcing element in its installed position.
Vorzugsweise ist dazu das Verstärkungselement auf einfache Weise an dem Federteller befestigt, indem der oder die sich radial nach außen erstreckenden Flansche eine radial umlaufende, radial gerichtete Schulter des Federtellers hintergreifen.Preferably, the reinforcing element is attached to the spring plate in a simple manner, by the or the radially outwardly extending flanges engage behind a radially encircling, radially directed shoulder of the spring plate.
Dabei kann das das Verstärkungselement ein Verstärkungsring mit einem Z-artigen Querschnitt sein.In this case, the reinforcing element may be a reinforcing ring with a Z-like cross-section.
Einfach als Blech-/Biegeteil aus einem Verstärkungsrohr ist das Verstärkungselement herstellbar, wenn das Verstärkungselement ein Verstärkungsring ist, der in Umlaufrichtung alternierend Abschnitte mit Z-artigem Querschnitt und zylindrischem Querschnitt aufweist.Simply as a sheet metal / bent part of a reinforcing tube, the reinforcing element can be produced if the reinforcing element is a reinforcing ring having alternately in the circumferential direction sections of Z-like cross-section and cylindrical cross-section.
Dazu können die radial gerichteten Flanschabschnitte Umbiegungen oder Einprägungen des Verstärkungsrohres sein.For this purpose, the radially directed flange sections may be bends or impressions of the reinforcing tube.
Sind es Umbiegungen, so kann der Verstärkungsring eine größere Wandstärke aufweisen, als sie zum Prägen noch geeignet ist, so dass die Sicherheit des Verstärkungselements gegen radiales Aufweiten sehr hoch sein kann.If they are bends, then the reinforcing ring can have a greater wall thickness than is still suitable for embossing, so that the security of the reinforcing element against radial expansion can be very high.
Zur Definition der Einbauposition kann das Verstärkungsrohr an dem Lagerausgangsteil axial abgestützt sein.To define the mounting position, the reinforcing tube may be axially supported on the bearing output part.
