Abstract
Description
Die Erfindung bezieht sich auf ein Kugelgelenk, bestehend aus einem Kugelzapfen und einem der Aufnahme des Kugelzapfens dienenden Gehäuse. The invention relates to a ball joint consisting of a Ball pin and a housing serving to receive the ball pin.
Es sind bereits Kugelgelenke bekannt (z. B. DE 199 58 149 A1), bei denen ein Kugelzapfen und ein Gehäuse aus Kunststoff vorgesehen sind, in der der Kugelzapfen dreh- und schwenkbar gehalten ist. Nachteilig ist hierbei, dass der Kugelzapfen direkt im Gehäuse angeordnet ist und damit mit einem entsprechend großen Losbrechmoment zu rechnen ist. Ball joints are already known (e.g. DE 199 58 149 A1), in which a Ball studs and a plastic housing are provided, in which the Ball pin is rotatably and pivotally held. The disadvantage here is that the Ball pin is arranged directly in the housing and thus with a a correspondingly large breakaway torque is to be expected.
Hiervor ausgehend ist es Aufgabe der Erfindung, ein Kugelgelenk zu schaffen, welches verschleißarm und gegen Geräusche isoliert ist und das darüber hinaus bei Auslenkung ein möglichst geringes Losbrechmoment aufweist. Proceeding from this, it is the object of the invention to create a ball joint, which is low-wear and insulated against noise and that in addition has a breakaway torque that is as low as possible during deflection.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, dass zwischen dem Kugelzapfen und dem Gehäuse ein elastisches Zwischenteil angeordnet ist. To solve this problem, the invention provides that between the ball pivot and the housing arranged an elastic intermediate part is.
Hierbei ist von Vorteil, dass das Kugelgelenk wegen der physikalischen Eigenschaft von Elastomer ein geringes Losbrechmoment bei Auslenkungen des Kugelzapfens aufweist. Darüber hinaus wird durch den Elastomer eine Geräuschisolierung vorgenommen und darüber hinaus vermindert der Elastomer bei Relativbewegungen zwischen den Bauteilen einen Verschleiß während des Betriebes. The advantage here is that the ball joint because of the physical Property of elastomer a low breakaway torque when deflecting the Has ball stud. In addition, a Made noise insulation and also reduces the elastomer Relative movements between the components wear during the Operation.
Nach einem weiteren wesentlichen Merkmal ist vorgesehen, dass das elastische Zwischenteil mindestens zweiteilig ausgebildet ist. According to a further essential feature, it is provided that the elastic Intermediate part is formed at least in two parts.
Eine günstige Ausführungsform sieht vor, dass das elastische Zwischenteil mit Halteelementen versehen ist. A favorable embodiment provides that the elastic intermediate part with Holding elements is provided.
Eine weitere Ausgestaltung sieht vor, dass die elastischen Zwischenteile vor der Montage kegelstumpfförmig ausgebildet sind. Hierbei lassen sich mit Vorteil die elastischen Zwischenteile nach der Montage des Gehäuses in den Zwischenraum zwischen Kugelzapfen und Gehäuse hineinverformen. Another embodiment provides that the elastic intermediate parts in front of the Assembly are frustoconical. Here, the elastic intermediate parts after mounting the housing in the Deform the space between the ball stud and the housing.
Nach einer weiteren Ausführungsform ist vorgesehen, dass das Gehäuse mindestens zweiteilig ausgebildet ist. Mit Vorteil ist hierbei vorgesehen, dass jedem Gehäuseteil mindestens ein elastisches Zwischenteil zugeordnet ist. According to a further embodiment it is provided that the housing is formed in at least two parts. It is advantageously provided that everyone Housing part is assigned at least one elastic intermediate part.
Eine weitere günstige Ausführungsform sieht vor, dass das jeweilige elastische Zwischenteil mit dem Halteelement und/oder dem Kugelzapfen und/oder dem Gehäuse durch Vulkanisation fest verbunden ist. Another cheap embodiment provides that the respective elastic Intermediate part with the holding element and / or the ball pin and / or the Housing is firmly connected by vulcanization.
Eine besonders günstige Fixierung der elastischen Zwischenteile lässt sich dadurch herstellen, dass die Halteelemente in Ausnehmungen des Gehäuses aufgenommen werden. A particularly favorable fixation of the elastic intermediate parts can be manufacture in that the holding elements in recesses of the housing be included.
Bevorzugte Ausführungsbeispiele der Erfindung sind in den Zeichnungen schematisch dargestellt. Preferred embodiments of the invention are in the drawings shown schematically.
Es zeigt: It shows:
Fig. 1 ein Kugelgelenk im Schnitt mit Gehäuse, Kugelzapfen und elastischen Zwischenteilen vor der Montage Fig. 1 shows a ball joint in section with the housing, ball stud and elastic intermediate parts before assembly
Fig. 2 ein Kugelgelenk nach erfolgter Montage im Schnitt. Fig. 2 shows a ball joint after assembly in section.
Bei dem in Fig. 1 dargestellten Kugelgelenk handelt es sich im einzelnen um die Gehäuseteile 1a und 1b, den Kugelzapfen 4 sowie den elastischen Zwischenteilen 3a und 3b. Die elastischen Zwischenteile 3a und 3b sind mit Halteelementen 2 versehen, die in Ausnehmungen 6 der Innenoberfläche des Gehäuses 1 aufgenommen werden. The ball joint shown in Fig. 1 is in detail the housing parts 1 a and 1 b, the ball pin 4 and the elastic intermediate parts 3 a and 3 b. The elastic intermediate parts 3 a and 3 b are provided with holding elements 2 , which are received in recesses 6 of the inner surface of the housing 1 .
In diesem Ausführungsbeispiel ist das elastische Zwischenelement 3 aus kegelstumpfförmigen Einzelteilen gebildet, die sich bei der Montage des Gehäuses 1, gemäß der Ausführungsform Fig. 2 derart verformen, dass sie zumindest einen großen Teil des Zwischenraumes zwischen dem Gehäuse 1 und dem Kugelzapfen 4 einnehmen. Es entsteht dadurch eine hohe Vorspannung des elastischen Zwischenteiles 3, so dass das Kugelgelenk über die gesamte Lebensdauer eine geringe Klapperneigung zeigt, das bedeutet ein geringes Spiel zwischen dem Kugelzapfen 4 und dem Gehäuse 1. In this exemplary embodiment, the elastic intermediate element 3 is formed from frustoconical individual parts which deform during assembly of the housing 1 , according to the embodiment in FIG. 2, such that they occupy at least a large part of the space between the housing 1 and the ball pin 4 . This results in a high preload of the elastic intermediate part 3 , so that the ball joint shows a slight tendency to rattle over the entire service life, which means that there is little play between the ball pin 4 and the housing 1 .
Aus der Fig. 2 ist zu entnehmen, dass das elastische Zwischenteil 3 zwischen dem Kugelzapfen 4 und dem Gehäuse 1 mit hoher Vorspannung eingebracht ist, so dass zwischen dem Gehäuse 1 und dem Kugelzapfen 4 keinerlei Relativbewegung stattfindet, diese wird durch das elastische Zwischenteil 3 ausgeführt, aus diesem Grunde kann auf die Härtung der Oberfläche des Kugelzapfens wie auch der Innenfläche des Gehäuses verzichtet werden. Schmiermittel für den Betrieb im Fahrzeugeinsatz sind ebenfalls nicht notwendig. From Fig. 2 it can be seen that the elastic intermediate part 3 is introduced between the ball pin 4 and the housing 1 with high prestress, so that no relative movement takes place between the housing 1 and the ball pin 4 , this is carried out by the elastic intermediate part 3 For this reason, the hardening of the surface of the ball pin as well as the inner surface of the housing can be dispensed with. Lubricants for use in vehicles are also not necessary.
Darüber hinaus kann auf Abdichtungen des Innenraumes verzichtet werden, da das elastische Zwischenteil den Einsatz von Dichtungen jeglicher Art überflüssig macht. In addition, there is no need to seal the interior, since the elastic intermediate part eliminates the use of seals of any kind makes.
Bei richtiger Bemessung des Volumens des elastischen Zwischenteiles 3 und einer entsprechenden Geometrie wird der Zwischenraum zwischen Kugelzapfen 4 und Gehäuse 1 einwandfrei gefüllt, so dass ein Überquellen und somit ein Abquetschen des elastischen Zwischenteiles an den Flächen 5 ausgeschlossen ist. With correct dimensioning of the volume of the elastic intermediate part 3 and a corresponding geometry, the space between ball stud 4 and housing 1 is filled properly, so that overflowing and thus squeezing of the elastic intermediate part on the surfaces 5 is excluded.
Die Fixierung der Gehäuseteile 1a und 1b miteinander ist in dieser
Ausführungsform nicht dargestellt und lässt sich durch Schweißen, Flanschverbindung
oder Pressverbindung beliebig herstellen.
