Abstract
Description
Die Erfindung betrifft einen Lenker einer Radaufhängung eines Kraftfahrzeuges in ein- oder zweischaliger Blechbauweise mit mehr als zwei Anlenkpunkten, von denen mindestens der in Fahrtrichtung des Kraftfahrzeuges vordere Anlenkpunkt als ein liegendes Schwenklager mit einer Lagerhülse ausgebildet ist, die an der am Anlenkpunkt als U-Profil gestalteten Schale befestigt ist.The The invention relates to a handlebar of a suspension of a Motor vehicle in one or two-sheet metal construction with more as two articulation points, of which at least the one in the direction of travel the motor vehicle front pivot point as a horizontal pivot bearing is formed with a bearing sleeve, which at the pivot point fastened as a U-shaped shell.
Federnd
abzustützende Räder in Kraftfahrzeugen sind an
Lenkern gehalten, die als Quer-, Schräg- oder Trapezlenker
ausgestaltet sein können. Bei einem bekannten als Querlenker
ausgebildeten Lenker in einschaliger Blechbauweise (
Der Erfindung liegt die Aufgabe zugrunde, einen Querlenker einer Radaufhängung eines Kraftfahrzeuges zu schaffen, dessen Herstellung einen vergleichsweise geringen Aufwand erforderlich macht, der aber gleichwohl die im Fahrbetrieb auftretenden hohen Belastungen dauerhaft aufzunehmen imstande ist.Of the Invention is based on the object, a control arm of a suspension to create a motor vehicle whose production is a comparatively requires little effort, but nevertheless in the Driving operation occurring high loads permanently incapable is.
Diese Aufgabe wird mit einem Querlenker der eingangs genannten Art dadurch gelöst, dass die Schenkel des U-Profils am Anlenkpunkt der Lagerhülse zwei fluchtende Löcher aufweisen, in denen die Lagerhülse mit Presssitz kraftschlüssig gehalten ist.These Task is characterized by a wishbone of the type mentioned by solved that the legs of the U-profile at the pivot point the bearing sleeve have two aligned holes, in which the bearing sleeve with interference fit non-positively is held.
Bei diesem Querlenker ist das Schwenklager mit seiner Lagerhülse in zwei mit Abstand voneinander angeordneten Ebenen mit dem Querlenker ausschließlich durch Kraftschluss verbunden. Diese Verbindung lässt sich mit geringem Aufwand herstellen. Sie ist in der Lage, die im Fahrbetrieb insbesondere beim Bremsen und bei Längsstößen auftretenden hohen Anschlaglasten dauerhaft aufzunehmen. Eine diesen Anforderungen genügende kraftschlüssige Verbindung lässt sich schon mit einer Blechdicke der Schale im Bereich der Löcher von 3 bis 5 mm realisieren. Bei solchen Blechstärken und bei einem entsprechenden Pressübermaß können Anpresskräfte von über 30 kN erzielt werden.at this wishbone is the pivot bearing with its bearing sleeve in two spaced-apart planes with the wishbone exclusively connected by traction. This connection can be produced with little effort. she is in the situation when driving, especially when braking and when longitudinal shocks permanently absorb occurring high impact loads. One of these Requirements sufficient frictional connection can be already with a sheet thickness of the shell in the area the holes from 3 to 5 mm realize. With such sheet thicknesses and at a corresponding Pressübermaß Contact forces of more than 30 kN can be achieved.
Zusätzlich zu der kraftschlüssigen Verbindung lässt sich mit geringem Aufwand aber auch eine formschlüssige Verbindung dadurch realisieren, dass die Lagerhülse mindestens einen Bund hat, mit dem sie außen an einem Schenkel anliegt, der der Richtung der erwähnten hohen Anschlaglasten zugewandt ist.additionally to the non-positive connection can be with little effort but also a positive connection realize that the bearing sleeve at least one Collar has, with which it rests on the outside of a leg, facing the direction of the mentioned high impact loads is.
In der Regel genügt es, wenn die Lagerhülse mit glatter Außenkontur in die Löcher eingepresst ist. Sofern eine zusätzliche Sicherung insbesondere gegen Verdrehung gewünscht wird, kann nach einer Ausgestaltung der Erfindung die Lagerhülse eine profilierte Außenkontur haben.In usually it is sufficient if the bearing sleeve with smoother Outer contour is pressed into the holes. Provided an additional safeguard against rotation in particular is desired, according to an embodiment of the invention the bearing sleeve have a profiled outer contour.
Für den gewünschten Presssitz ist es ausreichend, wenn die Außenkontur der Lagerhülse über ihre gesamte axiale Länge den gleichen Außendurchmesser hat und die Löcher den gleichen Durchmesser haben. Besonders leicht ist das Einsetzen der Lagerhülse aber dann, wenn der Durchmesser der Löcher und der Außendurchmesser der Lagerhülse abgesetzt sind, d. h. in Pressrichtung der Durchmesser des beim Einpressen der Lagerhülse zuerst erreichten Loches größer als das später erreichte Loch ist. Dann werden beim Einpressen der Hülse in die Löcher das in Pressrichtung vordere Loch und der vordere Teil der Lagerhülse materialmäßig weniger belastet als bei gleichen Durchmessern. Dies wirkt sich auch positiv auf die gewünschten Presssitze aus.For the desired interference fit, it is sufficient if the Outer contour of the bearing sleeve over their entire axial length the same outer diameter has and the holes have the same diameter. Especially but the insertion of the bearing sleeve is easy if the diameter of the holes and the outside diameter the bearing sleeve are discontinued, d. H. in the pressing direction of the diameter of the first achieved when pressing the bearing sleeve hole bigger than the hole reached later is. Then when pressing the sleeve in the holes the front hole in the pressing direction and the front part of the bearing sleeve material less loaded than the same Diameters. This also has a positive effect on the desired ones Press seats off.
Für den Aufbau der Lagerhülse gibt es zwei Alternativen. Entweder wird nur eine einteilige Lagerhülse aus Metall eingesetzt, in die dann später ein Gummilager eingesetzt wird, oder aber es wird eine kombinierte Lagerhülse aus einer dickwandigen Außenhülse aus Metall und einem darin bereits beim Einpressen sitzenden Gummilager eingesetzt.For The structure of the bearing sleeve, there are two alternatives. Either if only a one-piece bearing sleeve made of metal is used, in which then later a rubber bearing is used, or but it will be a combined bearing sleeve made of a thick-walled Outer sleeve of metal and one in it already used during pressing rubber seat.
