Description
Die Erfindung betrifft eine gerollte Buchse mit einem Längsschlitz gemäß den Merkmalen im Oberbegriff des Anspruchs 1.The The invention relates to a rolled bush with a longitudinal slot according to the characteristics in the preamble of claim 1.
Gerollte Buchsen mit einem Längsschlitz, bei welchen die den Längsschlitz begrenzenden Längskanten durch in Umfangsrichtung weisende Vorsprünge und Aussparungen sowie neben den Aussparungen vorgesehene Zungen und Einbuchtungen neben den Vorsprüngen miteinander verclincht sind, werden in vielen technischen Bereichen eingesetzt. Unter anderem finden sie eine Verwendung als Aufnahmen für Dämpfungselemente, wie beispielsweise Antivibrationssysteme in Kraftfahrzeugen.rolled Bushings with a longitudinal slot, in which the longitudinal slot limiting longitudinal edges by circumferentially facing projections and recesses as well next to the recesses provided tongues and indentations next to the projections are interlinked in many technical fields used. Among other things, they find use as recordings for damping elements, such as anti-vibration systems in motor vehicles.
Das Verclinchen von sich in Umfangsrichtung einer Buchse erstreckenden, an einer Längskante befindlichen Vorsprüngen mit der Konfiguration der Vorsprünge weitgehend angeglichenen Aussparungen an der gegenüber liegenden Längskante einerseits sowie neben den Aussparungen vorgesehenen Zungen und Einbuchtungen neben den Vorsprüngen andererseits ist bereits mit den Vorteilen behaftet, dass eine einwandfreie zug- und druckfeste Verbindung sowohl in Umfangsrichtung der Buchse als auch parallel zu ihrer Längsachse gewährleistet werden kann.The Clinching in the circumferential direction of a sleeve extending, on a longitudinal edge located protrusions with the configuration of the projections largely aligned recesses on the opposite longitudinal edge on the one hand and next to the recesses provided tongues and Indentations next to the projections On the other hand, already having the advantages that a flawless tension and pressure resistant connection both in the circumferential direction of the bush as also parallel to its longitudinal axis be guaranteed can.

Es hat sich aber gerade bei der Befestigung einer Buchse durch Schweißen gezeigt, dass durch die dann eintretenden unterschiedlichen Wärmespannungen Relativverschiebungen der Vorsprünge zu den Aussparungen und der Zungen zu den Einbuchtungen in radialer Richtung der Buchse nicht vermieden werden können, so dass die Maßhaltigkeit nicht mehr gegeben ist.It but has just been shown in the attachment of a socket by welding, that by the then entering different thermal stresses Relative displacements of the projections to the recesses and the tongues to the indentations in radial Direction of the bush can not be avoided, so the dimensional accuracy is not more is given.
Der Erfindung liegt – ausgehend vom Stand der Technik – die Aufgabe zugrunde, eine gerollte Buchse mit einem verbesserten statischen und dynamischen Belastungsverhalten zu schaffen.Of the Invention is - starting from the prior art - the Task underlying a rolled bush with an improved static and dynamic load behavior.
Diese Aufgabe wird mit den im Anspruch 1 angegebenen Merkmalen gelöst.These The object is achieved with the features specified in claim 1.
Die Erfindung sieht demnach vor, dass mindestens ein Vorsprung nach dem Verclinchen in einer Aussparung mit wenigstens einem dann benachbarten Buchsenabschnitt durch eine auf die äußeren Oberflächen des Vorsprungs und des Buchsenabschnitts radial aufgebrachte Presskraft verstemmt ist. Hierbei wird folglich das Material des Vorsprungs mit dem Material des angrenzenden Buchsenabschnitts über den hier befindlichen Schlitzabschnitt hinweg innig miteinander verklammert. Diese Verklammerung bewirkt, dass auch in radialer Richtung der Buchse wirksame Kräfte die Verclinchung der Vorsprünge und der Aussparungen einerseits sowie der Zungen und der Einbuchtungen andererseits nicht aufheben können. Die Funktion der Buchse wird aufrecht erhalten.The The invention therefore provides that at least one projection after the Verclinchen in a recess with at least one then adjacent Bushing section through one on the outer surfaces of the Projection and the sleeve portion radially applied pressing force is caulked. In this case, therefore, the material of the projection with the material of the adjacent socket section over the Here located slot section away intimately clamped together. This clamping causes that in the radial direction of the Socket effective forces the occlusion of the projections and the recesses on the one hand and the tongues and indentations on the other hand can not pick up. The function of the socket is maintained.
Durch die erfindungsgemäß vorgesehene Verstemmung in den Fügebereichen an den Längskanten einer Buchse kann eine ansonsten möglicherweise erforderliche Verschweißung in diesen Bereichen vermieden werden. Grundsätzlich ist es aber auch denkbar, zusätzlich zu den erfindungsgemäß vorgesehenen Verstemmungen Schweißpunkte zu setzen.By the inventively provided caulking in the joining areas at the longitudinal edges a socket may otherwise be required welding be avoided in these areas. In principle, it is also conceivable additionally to the inventively provided Caulking welds to put.
Das Verstemmen kann linienförmig oder auch flächenförmig erfolgen. Im letzteren Fall gelangt vorzugsweise ein im Querschnitt rechteckiger Pressstempel zum Einsatz, der das Material des Vorsprungs und des benachbarten Buchsenabschnitts verstemmt.The Caulking can be linear or even sheet-like. In the latter case preferably passes in a rectangular cross-section Press punches for use, the material of the projection and the caulked adjacent socket section.
Entsprechend den Merkmalen des Anspruchs 2 ist es von besonderem Vorteil, wenn ein Randbereich des Vorsprungs sowie ein benachbarter Randbereich des Buchsenabschnitts und/oder einer Zunge durch eine Materialverstemmung form- und kraftschlüssig miteinander verbunden sind.Corresponding The features of claim 2, it is of particular advantage, if an edge region of the projection and an adjacent edge region the bushing portion and / or a tongue by a Materialverstemmung positive and non-positive connected to each other.
Die Erfindung macht sich mit besonderem Vorteil bei einer solchen Buchse bemerkbar, bei welcher sich gemäß den Merkmalen des Anspruchs 3 die neben einem Vorsprung liegenden Einbuchtungen schräg zur Umfangsrichtung erstrecken. Hierbei handelt es sich insbesondere um keilförmige Einbuchtungen, die am inneren Ende gerundet sind.The Invention makes with particular advantage in such a socket noticeable at which according to signs of claim 3 lying next to a projection indentations aslant extend to the circumferential direction. These are in particular around wedge-shaped Indentations rounded at the inner end.
Die erfindungsgemäße Buchse ist besonders gut als Aufnahme für ein Dämpfungselement und Anschweißteil am Fahrwerk eines Kraftfahrzeugs geeignet (Anspruch 4).The inventive socket is especially good as a recording for a damping element and welding part on the chassis of a motor vehicle suitable (claim 4).
