Description

Schwingungsdämpfer oder Federung von teleskoparti e r Bauform mit durch Widerstandsschweißes angebrachten Befestigungsaugen Die Erfindung betrifft einen Schwingungsdämpfer oder eine Federung von teleskopartiger Bauform mit am Behälterrohrkörper und/oder an der Kolbenstange durch Widerstandsschweißung fest angebrachten Befestigungsaugen. Vibration damper or suspension of teleskoparti e r construction with attached by resistance sweat fastening eyes The invention relates to a vibration damper or a suspension of a telescopic design with the container tubular body and / or on the piston rod by resistance fixedly attached mounting eyes.

Bei den bekannten Bauelementen dieser Gattung, insbesondere Schwingungsdämpfern für Personenkraftwagen, sind die Befestigungsaugen durch Widerstandsschweißung befestigt. Dieser herstellungsmäßig ilorteilhaften Befestigungsart haftet aber der Nachteil an, daß da-Spritzer von beim Schweißen flüssig gewordenem Metall entstehen, die auch außen an dem Bauteil haften bleiben. Die-Entfernung dieser Spritzer zur Erlangung einer für den weiteren Fertigungsgang geeigneten Oberfläche ist verhältnismäßig aufwendig und deshalb unerwünscht. Der Erfindung liegt die.Aufgabe zugrunde, diesen Nachteil zu vermeiden.In the known components of this type, in particular vibration dampers for passenger cars, the fastening eyes are fastened by resistance welding. However, this type of fastening, which is part of the manufacturing process, has the disadvantage indicate that there are spatters of metal that has become molten during welding also stick to the outside of the component. The removal of these splashes to obtain a surface suitable for the further production process is proportionate expensive and therefore undesirable. The invention is based on the task, these Avoid disadvantage.

Gemäß der Erfindung geschieht dies nun dadurch, daß an dem Befestigungsauge eine eng anliegende, etwa schalenförmige Kappe vorgesehen ist, die das Befestigungsauge zu der Schweißverbindungsstelle hin abdeckt uni dabei einen unlösbaren Teil der Metallverbindung bildet. Eir«; vorte i lfiaf te Ausgestaltung der .Erfindung besteht darin, daß f1.Ee kappe aus metallischem, schweißbarem Werkstoff besteht. Mit diesen Maßnahmen wird in überaus einfacher und zugleich überraschender Weise erreicht, daß an der Oberfläche der Bauteile beim Schweißvorgang keine Metallspritzer mehr auftreten. Die bisher notwendige Verputzarbeit im Bereich der Schweißverbindungsstelle kann vollständig entfallen. Das Werkstück fällt nunmehr in einwandfreiem, sogleich zur Weiterbearbeitung geeignetem Zustand an.According to the invention, this is now done in that on the fastening eye a close-fitting, approximately cup-shaped cap is provided, which the fastening eye towards the weld joint, uni covers an inseparable part of the Metal compound forms. Eir «; Advantages in the lfiaf th design of the .invention exists that f1.Ee cap is made of a metallic, weldable material. With these measures are achieved in a very simple and at the same time surprising way, that no more metal splashes on the surface of the components during the welding process appear. The previously necessary plastering work in the area of the weld joint can be completely omitted. The workpiece now falls in perfect, instantly condition suitable for further processing.

Weitere vorteilhafte Einzelheiten der Erfindung sind nachstehend an Hand eines in der Zeichnung dargestellten Ausführungsbeispiels beschrieben. Es zeigen: Fig. Z eine Kolbenstange eines Schwingungsdämpfers mit daran angeordnetem Befestigungsauge und erfindungsgemäß zwischengelegter Kappe, in Schnittanrichte FILZ. 2 eine Kappe zum Befestigungsauge in Einzeldarstellung, vergrößert> im Schnitt.Further advantageous details of the invention are set out below Hand described an embodiment shown in the drawing. Show it: Z shows a piston rod of a vibration damper with a fastening eye arranged thereon and according to the invention interposed cap, in FELT cutting board. 2 a cap to the fastening eye in individual illustration, enlarged> in section.

In der Fig. 1 ist mit 1 eine Kolbenstange eines im übrigen nicht ge- zeigten Teleskop-Schwingungsdämpfers bezeichnet. Am in der Zeichnung oberen Ende trägt die Kolbenstange auf einem abgesetzten Endteil eine etwa topfförmige Kappe 2, die zum Anschluß eines nicht dargestellten Schutzrohres dient. An der plan ausgebildeten Stirnflc'_'chc der Kolbenstange 1 ist ein Befestigungsauge 3 durch Widerstandsschweißen angebracht. Zwischen der Abdeckkappe 2 und dem Befestigungsauge 3 ist eine etwa schalenförmige Kappe 4 vorgesehen, die das Befestigungsauge im Bereich der Schweißverbindungsstelle eng; umgibt und abdeckt. Diese Kappe 4 besteht vorteilhaft aus metal.li-,#;chem, schweißbarem Werkstoff und bildet auf diese Weise einen tiii -lösbaren Teil der Schweißverbindung, bei der an der Außenflicti,: der miteinander verbundenen Bauteile keine Spritzer von flüssig gewordenem Werkstoff auftreten. Eine irgendwie geartete Verputzarbeit ist daher bei der an Hand des Ausführungsbeispiels vorgeschriebenen Widerstandsschweißverbindung nicht erforderlich.In Fig. 1 a piston rod of a non-demonstrated overall in the other telescopic shock absorber is designated by 1. At the upper end in the drawing, the piston rod carries an approximately cup-shaped cap 2 on a stepped end part, which is used to connect a protective tube (not shown). A fastening eye 3 is attached by resistance welding to the flat end face of the piston rod 1. Between the cover cap 2 and the fastening eye 3, an approximately cup-shaped cap 4 is provided, which tightens the fastening eye in the area of the weld joint; surrounds and covers. This cap 4 is advantageously made of metal, chemical, weldable material and in this way forms a part of the welded joint that can be detached and in which no splashes of material that has become liquid occur on the external surface of the interconnected components. Any kind of plastering work is therefore not required for the resistance welded connection prescribed in the exemplary embodiment.

In Fit. 2 ist die zwischengefügte Kappe 4 vergrößert im einzelnen dargestellt. Diese Figur laßt die der Außenform des Befestigungsauges angepaßte Kontur der Kappe deutlich erkennen.In Fit. 2, the interposed cap 4 is enlarged in detail shown. This figure leaves the one adapted to the outer shape of the fastening eye Clearly see the contour of the cap.

Der Gedanke, bei einer Widgrstandsschweißverbindung in erfindungsgemäßer Weise eine Kappe vorzusehen, ist nicht nur bei dem beschriebenen Ausführungsbeispiel eines Schwingungsdämpfers mit teleskoparti= ger Bauform mit Vorteil anwendbar, sondern es eignen sich zur Anwendung ebenso rohrförmige Federungen oder sonstige Bauelemente, bei denen eine Schweißverbindung vorhanden ist, bei der möglichst wenig Verputzarbeit anfallen soll.The idea of a resistance welded connection in accordance with the invention Way to provide a cap is not only in the described embodiment a vibration damper with a telescopic design can be used with advantage, but tubular suspensions or other components are also suitable for use, where there is a welded joint, where the plastering work is as little as possible should be incurred.
