Abstract
Description
Die Erfindung betrifft ein Federbein für ein Fahrwerk eines Kraftfahrzeuges mit mindestens einem Zylinderrohr, das an einem Ende durch eine abdichtende Kolbenstangenführung und am anderen Ende durch ein Bodenteil begrenzt wird, einer in diesen eintauchenden, in einem Dämpfungskolben endenden Kol benstange und mindestens einem Federteller zur Aufnahme der Schraubenfeder.The invention relates to a shock absorber for a chassis Motor vehicle with at least one cylinder tube that one end through a sealing piston rod guide and is delimited at the other end by a bottom part, one in this plunging, ending in a damping piston rod and at least one spring plate to accommodate the Coil spring.
Federbeine bilden zusammenwirkend, vorzugsweise mit mecha nischen Federn, das Federungs- und Dämpfungssystem zwischen Radaufhängung und Fahrzeugaufbau. Häufig werden hierbei als Federungssysteme Schraubenfedern eingesetzt, die als Platz ersparnisgründen um den Schwingungsdämpfer gelegt sind. Die Schraubenfeder stützt sich an ihrem oberen und unteren Ende jeweils gegen einen Federteller ab, der üblicherweise mit dem Zylinderrohr des Ein- oder Zweirohrdämpfers verbunden ist. Aus der deutschen Patentanmeldung P 41 22 798 ist es be kannt, den Federteller mit dem Zylinderrohr durch Laser schweißen zu verbinden.Shocks form interacting, preferably with mecha African springs, the suspension and damping system between Suspension and vehicle body. Often this is considered Coil springs used as a space for reasons of economy are placed around the vibration damper. The Coil spring rests on its upper and lower ends each against a spring plate, usually with is connected to the cylinder tube of the one or two-tube damper. From German patent application P 41 22 798 it is be knows the spring plate with the cylinder tube by laser welding to join.
Beim Laserschweißen tritt die grundsätzliche Schwierigkeit auf, daß sehr hohe Anforderungen an die Herstell- und Po sitionsgenauigkeiten der zu verschweißenden Teile gestellt werden. Für die Anwendung des Laserschweißens sind oft Toleranzen zwischen den zu verschweißenden Teilen von 0,1 mm erforderlich. Damit ist es bei herkömmlichen Fe dertellern nicht möglich, diesen auf dem Zylinderrohr zu positionieren. The basic difficulty arises with laser welding on that very high demands on the manufacturing and Po accuracy of the parts to be welded become. For the application of laser welding are often Tolerances between the parts to be welded by 0.1 mm required. So it is with conventional Fe dertellern not possible to this on the cylinder barrel position.
Die Aufgabe der Erfindung ist es, einen Federteller zu schaffen, der bei Einhaltung der für das Laserschweißen notwendigen To leranzen auf einfache Weise auf dem Zylinderrohr positioniert werden kann.The object of the invention is to create a spring plate the observance of the To. required for laser welding lerances easily positioned on the cylinder barrel can be.
Die Aufgabe wird durch den kennzeichnenden Teil des Anspruchs 1 gelöst, wobei die Unteransprüche 2 bis 6 vorteilhafte Ausbil dungen darstellen.The object is achieved by the characterizing part of claim 1 solved, the sub-claims 2 to 6 advantageous training representations.
Die mit der Erfindung erzielten Vorteile liegen insbesondere darin, daß durch das so erzielte Auffedern des zylinderförmi gen Teils während des Aufschiebens des Federtellers auf das Zylinderrohr die für das Laserschweißen notwendigen Toleranzen zwischen den zu verschweißenden Teilen eingehalten werden können und das Zylinderrohr nicht deformiert wird.The advantages achieved with the invention are in particular in that by the springing of the cylinder-shaped partly during the sliding of the spring plate onto the Cylinder tube the tolerances necessary for laser welding can be maintained between the parts to be welded and the cylinder tube is not deformed.
Vorteilhafterweise können die Schlitze durch Materialscherung oder Materialentfernung, insbesondere Stanzen, auch während der Zieharbeitsgänge in den Federteller eingebracht werden.The slots can advantageously be sheared by material or material removal, especially punching, even during of the drawing operations are introduced into the spring plate.
Die Erfindung soll anhand eines Ausführungsbeispiels näher dar gestellt werden. Die zugehörigen Zeichnungen zeigen:The invention is intended to illustrate an exemplary embodiment be put. The associated drawings show:
Fig. 1 die Darstellung eines Federbeins, Fig. 1 is an illustration of a strut,
Fig. 2a einen Federteller, FIG. 2a is a spring plate,
Fig. 2b einen Ausschnitt aus dem zylinderförmigen Teil des Federtellers und Fig. 2b shows a section of the cylindrical part of the spring plate and
Fig. 3a bis 3d unterschiedliche Schlitzformen. FIGS. 3a-3d different slot shapes.
Fig. 1 zeigt den Ausschnitt aus einem Einrohr-Federbein, das ein Zylinderrohr 1 und eine in diesem eintauchende Kolben stange 3 aufweist, an deren unteren Ende ein nichtdargestellter Dämpfungskolben angeordnet ist. Weiterhin trägt das Zylinder rohr 1 den die nicht dargestellte Schraubenfeder aufnehmenden Federteller 5, der mit dem Zylinderrohr 1 mittels Laserschweißen verbunden ist. Fig. 1 shows the section of a single-tube strut, the cylinder tube 1 and a plunging rod in this rod 3 , at the lower end of which a damping piston, not shown, is arranged. Furthermore, the cylinder tube 1 carries the spring plate 5 , which is not shown, which is connected to the cylinder tube 1 by means of laser welding.
Bei Einrohr-Federbeinen ist es nicht möglich, den Federteller 5 mit konventionellen Schweißverfahren am Zylinderrohr 1 zu befestigen. Da der Dämpfungskolben an der Innenoberfläche gleitet muß diese hinsichtlich Rundheit und Linearität eine höchste Genauigkeit aufweisen. Eine solche Genauigkeit ist nur über Laserschweißverfahren zu erreichen.In the case of single-tube struts, it is not possible to attach the spring plate 5 to the cylinder tube 1 using conventional welding methods. Since the damping piston slides on the inner surface, it must be extremely precise in terms of roundness and linearity. Such accuracy can only be achieved using laser welding processes.
Um auch bei Einhaltung der für das Laserschweißen notwendigen Herstellungs- und Positioniergenauigkeiten ein Aufschieben des Federtellers 5 auf das Zylinderrohr 1 sowie eine genaue Po sitionierbarkeit zu gewährleisten, weist der zylinderförmige Verbindungsbereich 2 des Federtellers wenigstens einen über die gesamte Höhe des Verbindungsbereiches 2 verlaufenden Schlitz 6 auf, wodurch eine Spreizfederung des zylinderförmigen Verbin dungsbereichs 2 des Federtellers 5 beim Aufschieben auf das Zy linderrohr erzielt wird.In order to ensure that the spring plate 5 is pushed onto the cylinder barrel 1 and that it can be positioned accurately, even if the manufacturing and positioning accuracies required for laser welding are observed, the cylindrical connection area 2 of the spring plate has at least one slot 6 extending over the entire height of the connection area 2 , whereby an expansion suspension of the cylindrical connec tion area 2 of the spring plate 5 is achieved when pushed onto the cylinder tube Zy.
Eine sehr gute Spreizfederung wird erreicht, wenn, wie in Fig. 2b dargestellt, mehrere Schlitze 6 gleichmäßig über den Um fang des Verbindungsbereichs 2 des Federtellers 5 angeordnet werden.A very good spreading suspension is achieved if, as shown in Fig. 2b, several slots 6 are evenly arranged over the order of the connecting area 2 of the spring plate 5 .
Wie die Fig. 3a bis 3d zeigen, sind dabei die unterschied lichsten Formen der Schlitze 6 im Verbindungsbereich 2 mög lich.As shown in FIGS . 3a to 3d, the most varied shapes of the slots 6 in the connection area 2 are possible.
