Description
Die
Erfindung betrifft ein Kugelgelenk nach dem Oberbegriff von Patentanspruch
1. Ein solches Kugelgelenk ist aus der
Das Kugelgelenk umfasst einen Kugelzapfen mit Schaftbereich, Halsbereich und Kugel. Der Schaftbereich ist über einen Teil seiner Längserstreckung von einem Außenteil umfasst, das ein Gegenstück zu dem Schaftbereich bildet. Das Außenteil kann verschiedene Funktionen haben, je nachdem, wo das Kugelgelenk eingesetzt wird. Das Außenteil kann beispielsweise eine Schubstange sein, es kann sich um ein Fahrwerksbauteil wie einen Querlenker handeln, oder auch um ein Achsbauteil wie ein Schwenklager, einen Radträger oder dergleichen. Das Außenteil wird üblicherweise an dem Kugelzapfen festgeschraubt. Die Kugel des Kugelzapfens ist in einer Lagerschale eines Gelenkgehäuses des Kugelgelenks gleitbeweglich aufgenommen. Der Halsbereich des Kugelzapfens ist von einem Dichtungsbalg umgeben. Der Dichtungsbalg erstreckt sich ein wenig über den Halsbereich hinaus noch zu dem Schaftbereich an dessen Teil seiner Längserstreckung hin, der nicht von dem Außenteil umgeben ist. Der Dichtungsbalg weist einen umlaufenden Abschlussbund auf, der mittelbar oder unmittelbar an dem nicht von dem Außenteil umfassten Teil des Schaftbereichs anliegt.The Ball joint includes a ball stud with shank area, neck area and ball. The shank area is over part of its longitudinal extent from an outdoor part includes, that is a counterpart forms to the shaft area. The outdoor unit can have different functions depending on where the ball joint is used. The outer part can For example, be a push rod, it may be a suspension component act like a control arm, or even an axle component such as a pivot bearing, a wheel carrier or similar. The outer part becomes common bolted to the ball stud. The ball of the ball stud is slidable in a bearing shell of a joint housing of the ball joint added. The neck area of the ball stud is surrounded by a sealing bellows. The sealing bellows extends a little beyond the neck area nor to the shaft area at its part of its longitudinal extent out, not from the outside part is surrounded. The sealing bellows has a circumferential end collar on, the directly or indirectly on the not of the outer part covered part of the shaft area rests.
Die Anordnung muss eine Bewegung des Kugelzapfens relativ zum Dichtungsbalg ermöglichen, der Dichtungsbalg muss aber gleichzeitig die Aufgabe erfüllen, das Gelenk abzudichten.The Arrangement must be a movement of the ball stud relative to the bellows enable, But at the same time the sealing bellows must fulfill the task Seal joint.

Nachteilig ist, dass das externe Druckfederelement eine sehr hohe Kraft ausübt. Dies ist nachteilig, wenn der Kugelzapfen gedreht wird, denn der Dichtungsbalg wird dann unter Umständen verdrillt. Langfristig bewirkt ein solches Verdrillen eine vorzeitige Alterung des Dichtungsbalgs.adversely is that the external compression spring element exerts a very high force. This is disadvantageous when the ball pin is rotated, because the sealing bellows will then possibly twisted. In the long term, such a twisting causes premature Aging of the sealing bellows.
Es ist Aufgabe der Erfindung, ein Kugelgelenk der eingangs genannten Art auf derartige Weise weiterzubilden, dass die Abdichtung einerseits ausreichend zuverlässig ist, andererseits aber ein Verdrillen unterbunden wird.It Object of the invention, a ball joint of the aforementioned Type in such a way that the seal on the one hand sufficiently reliable on the other hand, twisting is prevented.
Die Aufgabe wird durch ein Kugelgelenk mit den Merkmalen gemäß Patentanspruch 1 gelöst.The Task is achieved by a ball joint with the features according to claim 1 solved.
Demgemäß ist am Übergang zwischen Schaftbereich und Halsbereich des Kugelzapfens an dem Kugelzapfen eine Schulter ausgebildet. Der umlaufende Abschlussbund stützt sich gleichzeitig an Schulter und Außenteil ab und ist hierbei elastisch vorgespannt.Accordingly, at the transition between shaft region and neck region of the ball stud on the ball stud a shoulder formed. The all-round final statement is supported at the same time on shoulder and outer part and is hereby elastically biased.
Während im Stand der Technik die Dichtkraft durch ein externes Druckfederelement bereitgestellt wird, wird im Rahmen der vorliegenden Erfindung ausschließlich die Elastizität des umlaufenden Abschlussbunds selbst verwendet. Damit können die wirkenden Kräfte insgesamt kleiner sein. Ein erfindungsgemäßer Dichtungsbalg ist einerseits gegen Wasser, Staub etc. sicher abgedichtet, anderseits verdrillt er sich aber nicht.While in the Prior art, the sealing force by an external compression spring element is provided in the context of the present invention excluding the elasticity used by the circulating Federation itself. This can be the acting personnel be smaller overall. An inventive sealing bellows is on the one hand securely sealed against water, dust etc., twisted on the other hand but he does not.
Bevorzugt ist in dem umlaufenden Abschlussbund (d. h. in seinem körperlichen Inneren) eine Feder angeordnet (welche kugelzapfenaxial vorgespannt ist).Prefers is in the encircling final covenant (that is, in his physical Inside) arranged a spring (which is Kugelzapfenaxial biased is).
Üblicherweise besteht der Dichtungsbalg aus einem Gummimaterial, und die Feder kann einfach in das Material des Dichtungsbalgs einvulkanisiert sein. Verwendet werden kann als Material für den Dichtungsbalg beispielsweise ein CR-Elastomer, wobei "CR" für "Chloroprene Rubber", Chloropren Gummi steht.Usually the sealing bellows consists of a rubber material, and the spring can easily be vulcanised into the material of the sealing bellows be. Can be used as a material for the bellows, for example a CR elastomer, where "CR" is "chloroprene rubber", chloroprene rubber stands.
Das erfindungsgemäße Kugelgelenk findet bevorzugte Anwendung in einem Kraftfahrzeug.The Ball joint according to the invention finds preferred application in a motor vehicle.
