Description
GM 341GM341
Die Erfindung bezieht sich auf eine Befestigungsvorrichtung eines Federbeines an einem Achsschenkel eines Kraftfahrzeugs, bei der ein unteres Federbeinende eine gabelförmige Aufnahme aufweist, die einen Haltesteg des Achsschenkels übergreift und durch Schrauben festsetzbar ist.The invention relates to a fastening device for a spring strut on a steering knuckle of a motor vehicle, in which a lower end of the spring strut has a fork-shaped receptacle which engages over a retaining web of the steering knuckle and can be secured by screws.
Aus der DE-A 36 29 431 ist eine Befestigungsvorrichtung eines Federbeines an einem Achsschenkel bekannt, bei der Schrauben zur Radeinstellung und zur Befestigung dienen.From DE-A 36 29 431 a fastening device for a spring strut to a steering knuckle is known, in which screws are used for wheel adjustment and fastening.
Die Anbindung des Achsschenkels am Federbein erfolgt aufgrund eines Reibschlusses, der durch die Schraubenvorspannkräfte erzeugt wird. Überschreiten die durch Radkräfte in die Verbindung eingeleiteten Querkräfte das in den Trennfugen übertragbare Kräftepotential, so kann eine Relativbewegung zwischen Achsschenkel und Federbein erfolgen und somit eine unerwünschte Verstellung der Radgeometrie.The connection of the steering knuckle to the suspension strut is based on a frictional connection that is generated by the bolt preload forces. If the transverse forces introduced into the connection by wheel forces exceed the force potential that can be transferred in the joints, a relative movement between the steering knuckle and suspension strut can occur, thus causing an undesirable adjustment of the wheel geometry.
Aufgabe der Erfindung ist es, eine Befestigungsvorrichtung eines Federbeines an einem Achsschenkel zu schaffen, die nach einem Einstellen des Rades eine unverschiebbare Verbindung zwischen Federbein und Achsschenkel gewährleistet.The object of the invention is to create a fastening device for a spring strut on a steering knuckle, which ensures a non-displaceable connection between the spring strut and the steering knuckle after the wheel has been adjusted.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichenden Merkmale des Anspruchs 1 gelöst. Weitere vorteilhafte Merkmale beinhalten die Unteransprüche.This object is achieved according to the invention by the characterizing features of claim 1. Further advantageous features are contained in the subclaims.
Die Verbindung zwischen einem Haltesteg eines Achsschenkels und der übergreifenden unteren Aufnahme des Federbeins erfolgt durch Schrauben. Zur Einstellung der Radgeometrie ist der Radträger relativ zum Federbein über einen gewissen Bereich variabel positionierbar. Die feste Verbindung wird durch Reibschluß nach Aufbringen der Schraubenanzugsmomente erreicht. Durch eine gezielt erzeugte Oberflächenstruktur wird die Reibungszahl in denThe connection between a retaining web of a steering knuckle and the overlapping lower mount of the suspension strut is made by screws. To adjust the wheel geometry, the wheel carrier can be positioned variably relative to the suspension strut over a certain range. The firm connection is achieved by frictional engagement after the screw tightening torques have been applied. The friction coefficient in the
GM 341GM341
Trennfugen der zu verbindenden Teile erhöht, wodurch das übertragbare Querkraftpotential vergrößert wird. Somit ist unter allen Betriebsbedingungen (Fahrsituationen) eine feste Verbindung zwischen Federbein und Radträger gewährleistet.Separation joints of the parts to be connected are increased, which increases the transferable lateral force potential. This ensures a firm connection between the suspension strut and the wheel carrier under all operating conditions (driving situations).
Die Oberflächenrauhigkeit besteht aus einfachen oder kreuzweisen Riffelungen, d.h. einer sogenannten Rändelung mit kreuzweise ausgeführten Riffelungen, die eine auf die Verhältnisse der Befestigung abgestimmte Tiefe aufweisen.The surface roughness consists of simple or crosswise corrugations, i.e. a so-called knurling with crosswise corrugations, which have a depth adapted to the conditions of the fastening.
Die Oberflächenrauhigkeit kann sowohl in den Anlageflächen des Haltestegs als auch in den Innenflächen der gabelförmigen Aufnahme des Federbeines vorgesehen sein.The surface roughness can be provided both in the contact surfaces of the retaining web and in the inner surfaces of the fork-shaped mount of the spring strut.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below.

Ein Federbein 1 eines Kraftfahrzeugs ist an einem Achsschenkel 2 über zwei Schrauben 3 und 4 befestigt. Hierzu weist das untere Federbeinende 5 eine gabelförmige Aufnahme 6 auf, die einen vertikal ausgerichteten Haltesteg 7 von beiden Seiten übergreift und an Anlageflächen 8 und 9 mit ihren Innenflächen 10 und 11 anliegt.A spring strut 1 of a motor vehicle is attached to a steering knuckle 2 via two screws 3 and 4. For this purpose, the lower end of the spring strut 5 has a fork-shaped holder 6, which overlaps a vertically aligned retaining web 7 from both sides and rests on contact surfaces 8 and 9 with their inner surfaces 10 and 11.
Die Anlageflächen 8, 9 weisen eine Oberflächenrauhigkeit auf, die vorzugsweise aus einer Riffelung besteht und Rillen 13 umfasst, die kreuzweise in die Fläche eingekerbt sind.The contact surfaces 8, 9 have a surface roughness which preferably consists of a corrugation and comprises grooves 13 which are crosswise notched into the surface.

Die Rillen sind vorzugsweise mit einer Rauhigkeit von einer Tiefe von 0,08 mm bis 0,2 mm ausgeführt.The grooves are preferably designed with a roughness of a depth of 0.08 mm to 0.2 mm.
Eine Ausbildung mit einfachen Rillen ist ebenso denkbar wie auch eine Oberflächenrauhigkeit der Anlageflächen 8 und 9 und der Innenflächen 10, der gabelförmigen Aufnahme 6 des Federbeines 1.A design with simple grooves is just as conceivable as a surface roughness of the contact surfaces 8 and 9 and the inner surfaces 10, of the fork-shaped mount 6 of the spring strut 1.
