Abstract
Eine Dichtung beinhaltet folgende Merkmale: - ein wenigstens in einem axialen Abschnitt ringartig ausgebildetes Versteifungselement, - an einem axialen Ende umfasst das Versteifungselement wenigstens einen axial vorstehenden Fortsatz, der außenmantelseitig derart mit einer Ausbauchung ausgebildet ist, dass er in einer Höhlung mit einer entsprechend ausgebildeten Einbauchung zum schnapphakenartigen Eingreifen vorgesehen ist, und - ein mit dem Versteifungselement verbundenes Dichtelement zum abdichtenden Anliegen an einem gegenüber der Höhlung dreh- und/oder längsbeweglichen Teil.A seal comprises the following features: a stiffening element which is of annular design at least in an axial section, at one axial end the stiffening element comprises at least one axially projecting extension which is formed with a bulge on the outer shell side in such a way that it forms a cavity with a correspondingly formed indentation is provided for snap hook-like engagement, and - a sealing element connected to the stiffening element for sealing engagement on a relative to the cavity rotatable and / or longitudinally movable part.
Description
Die Erfindung betrifft eine Dichtung.The The invention relates to a seal.
Aus dem Stand der Technik ist es beispielsweise bekannt, eine Dichtung gegen ein Herausdrücken aus einem Gehäuse dadurch zu sichern, dass ein in eine Gehäusenut einsetzbarer Sprengring verwendet wird.Out The prior art, for example, it is known a seal against pushing out from a housing to ensure that an insertable into a housing groove snap ring is used.
Eine Aufgabe der Erfindung ist es dabei, eine verbesserte gegen ein Herausdrücken aus einem Gehäuse gesicherte Dichtung zu schaffen.A The object of the invention is to provide an improved against squeezing a housing to create a secure seal.
Die Aufgabe wird durch den Gegenstand des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.The The object is solved by the subject matter of claim 1. advantageous Embodiments are described in the subclaims.
Gemäß Anspruch 1 beinhaltet eine Dichtung folgende Merkmale:
- – Ein wenigstens in einem axialen Abschnitt ringartig ausgebildetes Versteifungselement,
- – an einem axialen Ende umfasst das Versteifungselement wenigstens einen axial vorstehenden Fortsatz, der außenmantelseitig derart mit einer Ausbauchung ausgebildet sind, dass er in einer Höhlung mit einer entsprechend ausgebildeten Einbauchung zum schnapphakenartigen Eingreifen vorgesehen ist, und
- – ein mit dem Versteifungselement verbundenes Dichtelement zum abdichtenden Anliegen an einem gegenüber der Höhlung dreh- und/oder längsbeweglichen Teil.
- A stiffening element which is of annular design at least in an axial section,
- - At one axial end, the stiffening element comprises at least one axially projecting extension, the outer shell side are formed such with a bulge that it is provided in a cavity with a correspondingly formed indentation for snap hook-like engagement, and
- - A connected to the stiffening element sealing element for sealing engagement on a relative to the cavity rotatable and / or longitudinally movable part.
Dadurch, dass die Sicherungsfunktion gegen ein Herausdrücken sozusagen in das Versteifungselement der Dichtung integriert ist, kann gegenüber dem eingangs beschriebenen Stand der Technik mit Vorteil auf ein separates Element zur Sicherung gegen ein Herausdrücken verzichtet werden. Außerdem vereinfacht sich dadurch mit Vorteil auch die Montage der Dichtung. Bei korrektem Einbau ist die erfindungsgemäße Dichtung dabei mit Vorteil sozusagen selbstsichernd.Thereby, that the security function against pushing out so to speak in the stiffening element the seal is integrated, compared to the above-described State of the art with advantage on a separate element for securing against pushing out be waived. Furthermore This simplifies thereby advantageously the assembly of the seal. When correctly installed, the seal according to the invention is advantageous self-assured, so to speak.
