Description
Gebiet der ErfindungField of the invention
Die vorliegende Erfindung bezieht sich auf einen Lenker in der hinteren Radaufhängung in einem Fahrzeug, und insbesondere auf einen lang gestreckten, hinteren Lenker, der das untere Element in einer mehrgliedrigen Hinterradaufhängung ist, und ganz speziell auf einen unteren Lenker, der eine Feder oder Feder/Dämpfer-Einheit trägt.The present invention relates to a handlebar in the rear suspension in a vehicle, and more particularly to an elongated rear handlebar which is the lower member in a multi-unit rear suspension, and more particularly to a lower handle which has a spring or spring / Damper unit carries.
Stand der TechnikState of the art
Heute ziehen es Kraftfahrzeughersteller vor, Stahl-Komponenten durch entsprechende Aluminium-Komponenten zu ersetzen, um das Gewicht der Fahrzeuge niedrig zu halten. Es ist insbesondere wichtig, das Gewicht der beweglichen Teile in den Radaufhängungs-Komponenten zu verringern. Aluminium bietet sich besonders gut für diese Anwendung an, da es ein geringes Gewicht hat, beständig gegen Korrosion und sehr duktil ist.Today, automotive manufacturers prefer to replace steel components with corresponding aluminum components to keep the weight of the vehicles low. It is particularly important to reduce the weight of the moving parts in the suspension components. Aluminum is particularly suitable for this application as it has a low weight, is resistant to corrosion and is very ductile.
Aus der älteren
Es sind mehrere herkömmliche Lenker bekannt, die aus Stahl hergestellt sind, bei denen die Feder in einer Aussparung in dem Lenker angebracht ist. Dies hat den Vorteil, dass die Feder nicht zu weit in das Kraftfahrzeug-Chassis vorstehen wird, d. h., der obere Befestigungspunkt kann abgesenkt werden, wodurch mehr Raum im Kofferraum zur Verfügung steht. Diese Stahl-Komponente kann jedoch nicht leicht als Aluminium-Kopie ausgeführt werden. Ein solcher Lenker wird aus mehreren, einzelnen Stücken aus gestanztem Blechmetall herstellt, die miteinander verschweißt werden. Es ist nicht sinnvoll, mit dieser Technik einen Aluminiumlenker herzustellen, und zwar wegen der erforderlichen Schweißvorgänge. Schweißen von Aluminium ist ein delikates Verfahren, das weitgehend vermieden werden sollte, zumindest unter Berücksichtigung der Serienfertigung.There are several conventional links known, which are made of steel, in which the spring is mounted in a recess in the handlebar. This has the advantage that the spring will not project too far into the motor vehicle chassis, i. h., the upper attachment point can be lowered, leaving more space in the trunk available. However, this steel component can not be easily made as an aluminum copy. Such a handlebar is made of several, individual pieces of stamped sheet metal, which are welded together. It does not make sense to use this technique to produce an aluminum handlebar because of the welding required. Welding of aluminum is a delicate process that should be largely avoided, at least considering serial production.
Großserienherstellung verlangt die Verwendung von Schweißrobotern. Und das automatisierte Schweißen von Aluminium ist kompliziert:
- – Der Vorgang muss in einer inerten Atmosphäre durchgeführt werden.
- – Der Vorgang ändert die Eigenschaften des Materials in der Schweißnaht, deren Festigkeit ungünstig beeinflusst wird. Um die erforderliche Festigkeit zu erhalten, müssen die Materialabmessungen erhöht werden, was wiederum die Komponenten schwerer macht. Und Einsparen von Gewicht war ein Grund für die Verwendung von Aluminium.
- – Die Teile, die zusammengeschweißt werden sollen, müssen sehr eng aneinander angepasst sein; der maximale zulässige Spalt zwischen den Teilen beträgt ungefähr 0,2 mm. Um solche engen Toleranzen zu erzielen, müssen die einzelnen Teile mit großer Sorgfalt hergestellt werden, was möglicherweise spezielle Techniken involviert, wie beispielsweise Hydro-Formen. Diese Faktoren tragen dazu bei, dass geschweißte Aluminium-Aufhängungsteile sehr kostspielig sind.
- - The process must be carried out in an inert atmosphere.
- - The process changes the properties of the material in the weld whose strength is adversely affected. In order to obtain the required strength, the material dimensions must be increased, which in turn makes the components heavier. And saving weight was one reason for the use of aluminum.
- - The parts to be welded together must be very close together; the maximum permissible gap between the parts is approximately 0.2 mm. To achieve such close tolerances, the individual parts must be made with great care, possibly involving special techniques such as hydro-molding. These factors contribute to the fact that welded aluminum suspension parts are very expensive.
Es besteht die Herausforderung, Aufhängungsteile aus Aluminium zu einem wettbewerbsfähigen Preis herzustellen, da die Materialkosten im Vergleich mit Stahl höher sind. Die Antwort auf diese Herausforderung ist, alternative Herstellungsverfahren zu finden, die mit geringeren Kosten verbunden sind.The challenge is to produce aluminum suspension parts at a competitive price, as the material costs are higher compared to steel. The answer to this challenge is to find alternative manufacturing processes that are less expensive.
Kurze Zusammenfassung der ErfindungBrief summary of the invention
Es ist ein Ziel der vorliegenden Erfindung, einen Lenker aus Aluminium zu schaffen, der eine Platz sparende Befestigung einer Feder oder einer Feder/Dämpfer-Einheit ermöglicht.It is an object of the present invention to provide an aluminum handlebar which allows space saving attachment of a spring or spring / damper unit.
Es ist ein weiteres Ziel, diesen Lenker durch kosteneffektive Verfahren zu erzeugen und effektiv die Eigenschaften des Aluminiums auszunutzen, um einen Lenker großer Festigkeit zu erhalten.It is a further goal to produce this handlebar by cost-effective methods and to effectively exploit the properties of the aluminum to obtain a handlebar of great strength.
Es ist ein weiteres Ziel, den Lenker in einem Kaltverfahren herzustellen, das nur die externen Standard-Formverfahren involviert wie Schneiden, Streckbiegen, Lochstanzen etc.It is another aim to produce the handlebar in a cold process involving only the external standard forming processes such as cutting, stretch bending, hole punching, etc.
Diese Aufgaben werden bei einem Verfahren zur Herstellung eines Lenkers, wie es in Anspruch 1 beansprucht wird, und einem Lenker, wie er in dem folgenden Anspruch 3 beansprucht wird, erreicht.These objects are achieved in a method of manufacturing a handlebar as claimed in claim 1 and a handlebar as claimed in the following

Der Lenker wird in einem Verfahren mit fünf Schritten hergestellt, die in den
Im Schritt c wird das Profil an den Enden zusammengepresst. Im Schritt d wird der Federsitz durch Pressen und Ausbilden eines Lochs geformt. Die Formen der Enden werden eingestellt, indem überflüssiges Material weggeschnitten wird. Eine Gabel wird an dem linken Ende ausgebildet. Das Verfahren wird in Schritt e durch Ausbilden von Befestigungslöchern an den Enden vervollständigt. Hülsen bzw. Muffen werden später in die Löcher eingesetzt.In step c, the profile is pressed together at the ends. In step d, the spring seat is formed by pressing and forming a hole. The shapes of the ends are adjusted by cutting away excess material. A fork is formed at the left end. The process is completed in step e by forming mounting holes at the ends. Sleeves or sleeves are later inserted into the holes.
Damit ist das Herstellverfahren im Wesentlichen beendet, da keine weiteren Schritte für die Endbearbeitung erforderlich sind, wie beispielsweise Härten, Lackieren oder eine Anti-Korrosionsbehandlung. Das Verfahren ist sehr kompakt und involviert nur Kaltverarbeitungsschritte, d. h. kein Schweißen oder Schmieden. Es ist ein einfaches Verfahren, das mit Standard-Werkstatt-Werkzeugen ausgeführt werden kann.Thus, the manufacturing process is substantially completed, since no further steps for the finishing are required, such as curing, painting or anti-corrosion treatment. The process is very compact and involves only cold processing steps, i. H. no welding or forging. It's a simple process that can be done with standard workshop tools.
