Abstract
Description
Die Erfindung bezieht sich auf ein Kolben-Zylinder-Aggregat bestehend aus mindestens einem Außenrohr sowie verschiedenen Anbauteilen, wie beispielsweise Boden, Halter, Federteller, Befestigungsteile oder Stabilisator-Halter.The The invention relates to a piston-cylinder unit consisting from at least one outer tube as well as various attachments, such as floor, holder, spring plate, mounting hardware or stabilizer holder.
An
Außenrohren von Stoßdämpfern oder Federbeinen
werden regelmäßig Anbauteile (Anbindungsteile)
wie Brackets, Stabilisatorenhalter oder Federteller angebracht (z.
B.
Hiervon ausgehend ist es Aufgabe der Erfindung, ein Kolben-Zylinder-Aggregat mit den notwendigen Anbauteilen zu versehen, wobei möglichst auf Schweiß- Prozesse verzichtet wird und ein einwandfreier Korrosionsschutz zwischen den in Verbindung stehenden Teilen erzielt werden kann.Of these, Based on the object of the invention, a piston-cylinder unit to provide with the necessary attachments, where possible waived welding processes and a flawless Corrosion protection achieved between the related parts can be.
Zur Lösung dieser Aufgabe ist vorgesehen, dass mindestens eines der Anbauteile kraft- und/oder formschlüssig mit dem Außenrohr verbunden ist.to Solution to this problem is provided that at least one the attachments non-positively and / or positively with the outer tube connected is.
Hierbei ist von Vorteil, dass durch die Verbindung mit einem Formschluss und/oder einem Kraftschluss auf eine Schweißverbindung verzichtet werden kann, dabei lassen sich die Anbauteile nach der Hydraulikmontage des Kolben-Zylinder-Aggregates und der Funktionsprüfung anbringen, so dass hier auch eine Oberflächenbeschichtung vorgenommen werden kann, denn ohne einen Schweißprozess bleibt eine solche Oberflächenbeschichtung unzerstört.in this connection is advantageous in that by the connection with a positive connection and / or a traction on a welded joint can be omitted, it can be the attachments after the hydraulic assembly of the piston-cylinder unit and the functional test attach, so here also a surface coating can be made, because without a welding process remains such a surface coating is undamaged.
Ein weiterer Vorteil besteht darin, dass bei einer Verbauung der Anbauteile beim Kunden, sich der Transport der Kolben-Zylinder-Aggregate in einer höheren Packungsdichte vornehmen lässt. Ein Kolben-Zylinder-Aggregat zusammen mit seinen Anbauteilen ist deutlich sperriger und benötigt daher entsprechend mehr Raum in einer Transportbox.One Another advantage is that with a obstruction of the attachments at the customer, the transport of the piston-cylinder units in make a higher packing density. A piston-cylinder unit together with its attachments is significantly bulkier and therefore requires more accordingly Room in a transport box.
Nach einem weiteren wesentlichen Merkmal ist vorgesehen, dass das mindestens eine Anbauteil über einen Kraftschluss in Form einer Presspassung mit dem Außenrohr verbunden ist. Vorteilhaft ist hierbei, dass durch die vorgesehene Presspassung axiale Kräfte in radiale Kräfte umgeformt werden können.To Another essential feature is that the at least an attachment via a traction in the form of a press fit with connected to the outer tube. It is advantageous here that by the provided press fit axial forces in radial Forces can be reshaped.
Nach einem weiteren wesentlichen Merkmal ist vorgesehen, dass das mindestens eine Anbauteil im Bereich des zylindrischen Außenrohres einen mindestens teilweise aufgeweiteten Innendurchmesser aufweist, der kraftschlüssig mit über dem Umfang des Außenrohres verteilt angeordneten Nocken im Eingriff steht. Bei dieser Ausführungsform ist von Vorteil, dass die Anbauteile auf Nocken oder Ausprägungen aufgedrückt sind, dabei nehmen die Nocken bzw. die Ausprägungen die axialen Kräfte auf. Radialkräfte werden durch die Presspassung oder durch eine Negativform der Nocken bzw. Außenrohrkontur aufgenommen. Somit kann auch ein Anbauteil in Form eines Stabilisatorhalters Radialkräfte auf das Außenrohr übertragen.To Another essential feature is that the at least an attachment in the region of the cylindrical outer tube has an at least partially expanded inner diameter, the non-positively with over the circumference of the outer tube distributed cam is engaged. In this embodiment is advantageous that the attachments on cams or forms are pressed, taking the cams or the characteristics the axial forces. Radial forces are going through the press fit or by a negative shape of the cam or outer tube contour added. Thus, also an attachment in the form of a stabilizer holder Radial forces transmitted to the outer tube.
Werden mehrere Anbauteile axial hintereinander auf dem Außenrohr aufgefädelt, so können sich diese Anbauteile axial aneinander abstützen.Become several attachments axially one behind the other on the outer tube Threaded, so these attachments can be axial support each other.
Darüber hinaus ist vorgesehen, dass als Nocken eine über dem Umfang des Außenrohres verlaufende, sich von innen nach radial außen erstreckende, Ausprägung vorgesehen ist. Hierbei ist mit Vorteil vorgesehen, dass die Ausprägung sich über den gesamten Umfang des Außenrohres erstreckt.About that It is also envisaged that as a cam one over the circumference of the outer tube extending, from inside to radially Outwardly extending, expression is provided. It is provided with advantage that the expression over the entire circumference of the outer tube extends.
Nach einer fertigungstechnisch günstigen Ausführungsform ist vorgesehen, dass das Außenrohr einseitig geschlossen durch Tiefziehen und/oder Kumpeln hergestellt ist. Durch dieses schweißfreie Fertigungsverfahren des Außenrohres und der schweißnahtfreien Verbindung der Anbauteile am Außenrohr, entsteht ein komplett schweißnahtfreier Schwingungsdämpfer bzw. Federbein.To a manufacturing technology favorable embodiment is provided that the outer tube closed on one side is made by deep drawing and / or pals. Because of this welding-free production process of the outer tube and the weld-free connection of the attachments to the outer tube, creates a completely weld-free vibration damper or suspension strut.
Einem einwandfreien Korrosionsschutz wird dadurch Rechnung getragen, dass das Außenrohr und/oder das mindestens eine Anbauteil zumindest auf den einander zugewandten Flächen oberflächenbeschichtet ist.a Perfect corrosion protection is taken into account by the fact that the outer tube and / or the at least one attachment at least the surfaces facing each other surface-coated is.
Eine montagefreundliche Konstruktion ist dadurch gegeben, dass bei Verwendung mehrerer Anbauteile das Aufbringen auf das Außenrohr, ausgehend von beiden Enden des Außenrohrs erfolgt, so dass das Außenrohr vom jeweiligen Ende gesehen hinterschnittfrei ausgebildet ist.A Easy to assemble construction is given by that when using several attachments applying to the outer tube, starting from both ends of the outer tube, so that the outer tube Seen from the respective end is undercut trained.
Bevorzugte Ausführungsbeispiele der Erfindung sind in den Zeichnungen schematisch dargestellt.preferred Embodiments of the invention are in the drawings shown schematically.

der Schnittdarstellung gemäß
Die Herstellung einer schweißfreien Ausführung hat den weiteren Vorteil, dass das Außenrohr als auch die Anbauteile beschichtet sein können, um somit korrosionsfrei ausgeführt zu werden. Durch die Verwendung einer schweißfreien Konstruktion wird auch an diesen Stellen, wo üblicherweise die Schweißnaht erfolgt, der Korrosionsschutz Bestand haben.The Manufacture of a weld-free design has the further advantage that the outer tube as well as the attachments may be coated so as to be corrosion-free to become. By using a sweat-free construction is also used in these places, where usually the weld takes place, the corrosion protection stock.
