Abstract
Description
Die Erfindung betrifft einen Fahrwerklenker in Blechbauweise für ein Kraftfahrzeug mit mehreren Anschlusspunkten, mit denen er mit der Karosserie und einem dynamisch bewegten Teil des Kraftfahrzeuges verbindbar ist, wobei ein Anschlusspunkt von einem Zapfen gebildet wird, der in einem Blecharm des Lenkers gehalten ist.The The invention relates to a suspension link in sheet metal construction for a motor vehicle with several connection points, with which he with the body and a dynamically moving part of the motor vehicle is connectable, wherein a connection point formed by a pin which is held in a sheet arm of the handlebar.
Fahrwerkslenker, die ein Bindeglied zwischen der Karosserie eines Kraftfahrzeuges einerseits und dynamisch beweglichen Teilen, insbesondere Radträger, Feder, Dämpfer und Stabilisatoren andererseits bilden, sind in verschiedenen Ausführungen bekannt. Sie können als gegossene Bauteile oder als Schalen aus Stahlblech ausgebildet sein. Bei einem solchen Fahrwerkslenker kommt es neben seiner Formsteifigkeit und Lebensdauereigenschaften auch auf sein Gewicht als ungefederte Masse an.Suspension arm, which is a link between the bodywork of a motor vehicle on the one hand and dynamically moving parts, in particular wheel carriers, Form spring, damper and stabilizer on the other hand, are known in different versions. You can as cast components or as shells made of sheet steel be. In such a control arm it comes next to its stiffness and Lifetime features also on its weight as unsprung Mass.
Ein
bekannter Fahrwerkslenker der eingangs genannten Art (
Der Erfindung liegt die Aufgabe zugrunde, einen Fahrwerkslenker zu schaffen, der bei geringen Fertigungskosten eine hohe Formsteifigkeit und ein geringes Gewicht hat.Of the Invention has for its object to provide a suspension link, the at low production costs a high dimensional stability and has a low weight.
Diese Aufgabe wird erfindungsgemäß mit einem Fahrwerkslenker der eingangs genannten Art dadurch gelöst, dass der Lenker einschalig ausgebildet ist und sein Blecharm in eine Tülle ausläuft, die den Zapfen mit einem Umschlingungswinkel von mindestens 270° umschließt und mit dem Zapfen stoffschlüssig verbunden ist.These Object is according to the invention with a suspension link of the type mentioned solved in that the handlebar is formed einschalig and its Blecharm in a spout leaking out the pin with a wrap angle of at least 270 ° and cohesively with the pin connected is.
Der erfindungsgemäße Fahrwerkslenker lässt sich wegen der einschaligen Blechbauweise kostengünstig herstellen und hat ein geringes Gewicht. Die Verbindung zwischen Tülle und Zapfen durch Formschluss mit großem Umschlingungswinkel und Stoffschluss steht der herkömmlichen Verbindung bei dem bekannten zweischaligen Fahrwerkslenker nicht nach.Of the Suspension arm according to the invention leaves because of the einschaligen sheet metal construction cost produce and has a low weight. The connection between Spout and pin by form-fitting with large Wrap angle and fabric bond is the conventional Connection in the known bivalve suspension handlebars not to.
Nach einer ersten Ausgestaltung der Erfindung wird die stoffschlüssige Verbindung von einer am vorderen Rand der Tülle vorgesehenen Schweißnaht gebildet. Eine solche Schweißnaht lässt sich nach Einfügen des Zapfens in die Tülle problemlos realisieren.To A first embodiment of the invention is the cohesive Connection of one provided at the front edge of the spout Weld formed. Such a weld can be after inserting the pin in the spout easily realize.
Der große Umschlingungswinkel der Tülle sollte zwischen 300° und 360° betragen. Gute Erfahrungen wurden sowohl hinsichtlich der Herstellbarkeit der Tülle als auch hinsichtlich der dauerfesten Verbindung mit einem Umschlingungswinkel zwischen 320° und 340° erzielt.Of the large wrap angle of the spout should be between 300 ° and 360 °. Good experiences were both in terms of manufacturability of the spout and in terms of the permanent connection with a wrap angle between 320 ° and 340 ° achieved.
Um ein möglichst geringes Gewicht bei hoher Formsteifigkeit zu erzielen, sollte das Blech eine Dicke von 2 mm bis 6 mm und eine Festigkeit von 350 MPa bis 1000 MPa haben. Vorzugsweise sollte das Blech aus Dualphasenstahl bestehen. Auch sogenannte Complexphasenstähle oder Thermomechanisch gewalzte Kaltformstähle sind gut geeignet, wenn höhere Festigkeiten gewünscht werden.Around the lowest possible weight with high stiffness To achieve, the sheet should have a thickness of 2 mm to 6 mm and a Have strength of 350 MPa to 1000 MPa. Preferably, the sheet should consist of dual phase steel. Also so-called complex phase steels or thermomechanically rolled cold-forming steels are good suitable if higher strengths are desired.
Positiv wirkt sich hinsichtlich einer dauerhaften und formsteifen Verbindung aus, wenn der Zapfen auf einem im Durchmesser größeren Sockel sitzt, mit dem er in der Tülle steckt. Der Zapfen mit seinem Sockel kann als hohles Blechformteil oder Fließpressteil ausgebildet sein. Auch dieses Blechformteil sollte eine möglichst hohe Festigkeit haben, mindestens aus Dualphasenstahl bestehen.positive Affects a permanent and dimensionally stable connection off when the pin on a larger in diameter Socket sits, with which he puts in the spout. The pin with its base can be used as a hollow sheet metal part or extruded part be educated. Also this sheet metal part should be as possible have high strength, at least consist of dual phase steel.
Gegenstand der Erfindung ist außerdem ein Verfahren zur Herstellung eines Fahrwerkslenkers, das durch folgende Verfahrensschritte gekennzeichnet ist:
- • Umformen eines flachen Blechzuschnittes zu einer Blechschale mit im Bereich der späteren Tülle gegenüber den übrigen Rändern überhöhten, nach außen weisenden Randabschnitten.
- • Beschneiden der Ränder der Blechschale derart, dass die beschnittenen Kanten der Randabschnitte von dem Bereich der Tülle in die anschließenden, niedrigeren Kanten der Ränder der übrigen Blechschale kontinuierlich übergehen.
- • Umbiegen der Randabschnitte derart, dass sie mit dem zwischen ihnen liegenden Bereich der Tülle ein U-Profil mit Steg und Schenkeln bilden.
- • Umformen der Schenkel und des zwischen ihnen liegenden Bereichs der Tülle um einen den Abmessungen des Zapfens entsprechenden Füllschieber durch äußere auf die Randabschnitte und den dazwischen liegenden Bereich radial einwirkende Formwerkzeuge zu einer Tülle.
- • Nach Entfernen der Formwerkzeuge und den Füllschiebern, Einfügen und stoffschlüssiges Verbinden des Zapfens. Dabei wird vorzugsweise der Zapfen mit der Tülle durch eine umlaufende Schweißnaht am vorderen Rand der Tülle verbunden.
- • Forming of a flat sheet metal blank to a sheet metal shell with in the region of the later spout over the other edges of excessive, outwardly facing edge portions.
- • Trimming the edges of the sheet metal shell such that the trimmed edges of the edge portions continuously merge from the area of the spout into the subsequent, lower edges of the edges of the remaining sheet metal shell.
- • bending over the edge sections in such a way that they form a U-profile with web and legs with the area of the nozzle lying between them.
- • Forming the legs and the lying between them area of the spout to a the dimensions of the pin corresponding Füllschieber by outer on the edge portions and the intermediate area radially acting form tools to a spout.
- • After removal of the molds and the fillers, insertion and cohesive connection of the pin. In this case, the pin is preferably connected to the spout by a circumferential weld at the front edge of the spout.
