Abstract
Description
Die Erfindung betrifft ein Lagerelement, insbesondere zur Lagerung eines Lenkerelements eines Fahrwerks für einen Kraftwagen der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The invention relates to a bearing element, in particular for the storage of a link element of a chassis for a motor vehicle specified in the preamble of claim 1. Art.
Derartige Lagerelemente sind aus dem Serienbau von Kraftwagen bekannt und dienen beispielsweise dazu, ein Lenkerelement eines Fahrwerks des Kraftwagens, insbesondere eines Personenkraftwagens, an der Kraftwagenkarosserie zu lagern. Die Lagerelemente umfassen dabei jeweils ein elastisches Element, das eine Lageraufnahme zum Aufnehmen eines Lagerteils des über das Lagerelement zu lagernden Lenkerelements aufweist. Die Lageraufnahme ist dabei in radialer Richtung von einer Innenumfangsfläche des elastischen Elements begrenzt. Es hat sich gezeigt, dass die Montage des Lagerteils in der Aufnahme aufwändig ist.Such bearing elements are known from the mass production of motor vehicles and serve, for example, to store a link element of a chassis of the motor vehicle, in particular a passenger car, to the motor vehicle body. In each case, the bearing elements comprise an elastic element which has a bearing receptacle for receiving a bearing part of the link element to be mounted over the bearing element. The bearing receiver is limited in the radial direction by an inner circumferential surface of the elastic element. It has been shown that the mounting of the bearing part in the receptacle is complex.
Die
Es ist daher Aufgabe der vorliegenden Erfindung, die Reibung beim Aufpressen eines zu lagernden Bauteils, insbesondere eines Lenkerelements, in einer Lageraufnahme, insbesondere in einem elastischen Element, zu reduzieren.It is therefore an object of the present invention to reduce the friction during the pressing of a component to be supported, in particular a link element, in a bearing receptacle, in particular in an elastic element.
Diese Aufgabe wird durch ein Lagerelement, insbesondere zur Lagerung eines Lenkerelements eines Fahrwerks für einen Kraftwagen, mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nichttrivialen Weiterbildungen der Erfindung sind in den übrigen Ansprüchen angegeben.This object is achieved by a bearing element, in particular for the storage of a link element of a chassis for a motor vehicle, having the features of patent claim 1. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the remaining claims.
Ein solches Lagerelement, insbesondere zur Lagerung eines Lenkerelements eines Fahrwerks für einen Kraftwagen, insbesondere einen Personen- oder Nutzkraftwagen, umfasst eine Hülse, wobei diese zumindest bereichsweise in einem elastischen Element eingebracht ist. Vorteilhaft ist dabei, dass beim Einpressen während der Montage und/oder beim Ab- und beim erneuten Aufpressen im Service ein mögliches Verkanten des Lenkerelements im elastischen Element sicher vermieden wird, so dass das Lenkerelement unbeschädigt bleibt.Such a bearing element, in particular for the storage of a link element of a chassis for a motor vehicle, in particular a passenger or commercial vehicle, comprises a sleeve, which is at least partially introduced in an elastic element. It is advantageous that when pressing in during assembly and / or when off and re-pressing in service a possible tilting of the link element in the elastic element is reliably avoided, so that the link remains undamaged.
Weiterhin ist es vorteilhaft, dass eine Außenumfangsfläche der Hülse mit der gesamten Innenumfangsfläche des elastischen Elements korrespondiert. Dadurch, dass die Hülse und das elastische Element die gleiche Kontur aufweisen, ist eine kraftschlüssige Verbindung zwischen den beiden Bauteilen bspw. auch bei einer gestuften Ausführung des elastischen Elements ermöglicht.Furthermore, it is advantageous that an outer circumferential surface of the sleeve corresponds to the entire inner circumferential surface of the elastic element. Due to the fact that the sleeve and the elastic element have the same contour, a non-positive connection between the two components, for example, is also possible with a stepped embodiment of the elastic element.
Die Außenumfangsfläche der Hülse weist eine sich axial erstreckende durchgängige Unterbrechung auf. Diese schlitzförmige Unterbrechung ermöglicht eine radiale Verkleinerung der Hülse beim Einbringen der Hülse in das elastische Element. Ebenso ermöglicht die Unterbrechung eine radiale Aufweitung Hülse beim Einführen des Lenkerelements in die Hülse, sodass dieser Vorgang erleichtert wird.The outer peripheral surface of the sleeve has an axially extending continuous interruption. This slot-shaped interruption allows a radial reduction of the sleeve during insertion of the sleeve in the elastic element. Likewise, the interruption allows a radial expansion sleeve during insertion of the link member in the sleeve, so that this process is facilitated.
Vorzugsweise ist die Hülse aus Stahl gefertigt. Vorteilhaft ist dabei, dass der Werkstoff Stahl ausreichend stabil und zudem auch Vorspannung der Hülse ermöglicht. Weiterhin ist es vorteilhaft, wenn die aus Stahl gefertigte Hülse einen Oberflächenschutz aufweist. Vorzugsweise ist der Oberflächenschutz vollflächig auf die gesamte Hülse (im Innen- und Außenbereich) aufgebracht, so dass eine Korrosion der Hülse sicher vermieden wird. Der Oberflächenschutz kann bspw. eine geeignete Lackschicht sein. Insbesondere bei einem elastischen Element aus einem Kunststoff oder einem Elastomer, insbesondere Gummi, ist darauf zu achten, dass der Oberflächenschutz auf den Werkstoff des elastischen Elements abgestimmt ist, so dass eine chemische Reaktion zwischen den beiden Stoffen ausbleibt.Preferably, the sleeve is made of steel. It is advantageous that the steel material sufficiently stable and also allows biasing of the sleeve. Furthermore, it is advantageous if the sleeve made of steel has a surface protection. Preferably, the surface protection is applied over the entire surface of the entire sleeve (in the interior and exterior), so that corrosion of the sleeve is reliably avoided. The surface protection may, for example, be a suitable lacquer layer. In particular, in the case of an elastic element made of a plastic or an elastomer, in particular rubber, care must be taken that the surface protection is matched to the material of the elastic element, so that a chemical reaction between the two substances does not occur.
Ein weiterer Vorteil der Erfindung wird darin gesehen, dass die axiale Erstreckung der Hülse geringer als die axiale Erstreckung des elastischen Elements ist. Hierdurch wird einerseits das beschädigungsfreie Einbringen des Lenkerelements in das Lagerelement ermöglicht und andererseits eine kostengünstige Lösung, durch einen reduzierten Materialeinsatz, geschaffen.Another advantage of the invention is seen in that the axial extent of the sleeve is less than the axial extent of the elastic element. As a result, on the one hand the damage-free introduction of the link element in the bearing element allows and on the other hand, a cost-effective solution, created by a reduced use of materials.
Die Hülse weist an einer Innenkante eine Fase auf, wodurch das Aufpressen des Lagerelements auf das Lenkerelement erleichtert wird. Ebenso vorteilhaft ist es, dass die Hülse an einer Außenkante eine Fase aufweist, wodurch das Einpressen der Hülse in das elastische Element erleichtert wird.The sleeve has a bevel on an inner edge, whereby the pressing of the bearing element is facilitated on the link element. As well It is advantageous that the sleeve has a bevel on an outer edge, whereby the pressing of the sleeve is facilitated in the elastic element.
