B. for vehicle steering systems, which has a collar portion (3) at least one end, at the outer periphery (5) at least one annular fastening element (7) of rubber-elastic material and on the inner circumference (8) in each case at least one annular sealing element (9 ) are arranged from rubber-elastic material, characterized in that the at least one fastening element (7), the at least one sealing element (9) and the collar region (3) are permanently connected to each other inseparably connected components of the sleeve (1).
Description
Die Erfindung betrifft die Dichtung und Befestigung einer Manschette, z. B. für Fahrzeuglenkungen, die einen Bundbereich an mindestens einem Ende aufweist, an dem am Aussenumfang jeweils mindestens ein ringförmiges Befestigungselement aus gummi-elastischem Material und am Innenumfang jeweils mindestens ein ringförmiges Dichtelement aus gummi-elastischem Material angeordnet sind.The invention relates to the seal and attachment of a sleeve, z. B. for vehicle steering systems, which has a collar region at least at one end to the outer circumference in each case at least one annular fastening element made of rubber-elastic material and the inner circumference in each case at least one annular sealing element made of rubber-elastic material are arranged.
Derartige Manschetten sind z. B. aus den Schriften
Der feste und dichte Sitz des Bundbereiches auf dem zugehörigen Sitzbereich erfolgt durch Befestigungsmittel, wie z. B. Schellen, Drahtfedern, Spannringen oder -bändern. Solche Befestigungsmittel bestehen aus Blech, Edelstahl oder anderem Metall, können aber auch aus einem dauerelastischen Kunststoff bestehen.The tight and tight fit of the waistband area on the associated seating area is done by fasteners, such. As clamps, wire springs, clamping rings or bands. Such fasteners are made of sheet metal, stainless steel or other metal, but may also consist of a permanently elastic plastic.
Üblicherweise erfolgt die Montage der Befestigungsmittel erst im Zusammenhang mit der Montage des Faltenbalges auf die dicht zu verbindenden Teile. Dabei ist ein zusätzlicher Aufwand notwendig, damit es nicht zu Montagefehlern, z. B. durch zu starke oder lose Klemmung der Befestigungsmittel mit der damit verbundenen Beschädigung von Dichtelementen und/oder Faltenbalg kommt. Außerdem ist ein logistischer Aufwand für die separate Vorhaltung von Befestigungsmitteln und Dichtelementen erforderlich.Usually, the mounting of the fastening means takes place only in connection with the assembly of the bellows on the tightly connected parts. In this case, an additional effort is necessary so that it does not cause assembly errors, eg. B. comes due to excessive or loose clamping of the fastener with the associated damage of sealing elements and / or bellows. In addition, a logistical effort for the separate provision of fasteners and sealing elements is required.
Ein weiteres Problem von Manschetten der genannten Art ist, dass das Material der Faltenbälge häufig als Abdichtung im Bund/Sitzbereich nicht optimal geeignet ist, weil es z. B. zu hart ist. Deshalb finden in diesen Fällen bei der Montage zusätzliche Dichtelemente Verwendung, die z. B. in Form von O-Ringen zwischen Bundbereich der Faltenbälge und Sitzbereich der Anschlussteile angeordnet sind. Dabei ist zur Vermeidung der hier möglichen Montagefehler, z. B. die Dichtelemente werden vergessen oder beim Aufziehen durch Verkanten verschoben, ebenfalls Zusatzaufwand erforderlich.Another problem of cuffs of the type mentioned is that the material of the bellows is often not ideal as a seal in the collar / seating area, because it is z. B. is too hard. Therefore, find in these cases during installation additional sealing elements use z. B. in the form of O-rings between the waistband region of the bellows and seating area of the connecting parts are arranged. It is to avoid the possible assembly errors here, z. B. the sealing elements are forgotten or moved when mounting by tilting, also additional effort required.
Diesem Missstand tragen die
Es sind weiterhin auch eine lose Vormontage der Befestigungsmittel bzw. vorbefestigte Dichtelemente vorgeschlagen worden. Die
Der Erfindung liegt daher die Aufgabe zugrunde, eine Manschette der eingangs beschriebenen Art zu schaffen, die unter Vermeidung der vorgenannten Nachteile eine einfache und sichere Montage gewährleistet.The invention is therefore an object of the invention to provide a sleeve of the type described above, which ensures a simple and safe installation while avoiding the aforementioned disadvantages.
Diese Aufgabe wird dadurch gelöst, dass das mindestens eine Befestigungselement, das mindestens eine Dichtelement und der Bundbereich miteinander unlösbar fest verbundene Bestandteile der Manschette sind. Dadurch ergibt sich der Vorteil, dass die Elemente bei der Montage nicht vergessen werden können, womit eine erhöhte Arbeits- und Betriebssicherheit verbunden ist. Außerdem ist der logistische Aufwand deutlich geringer, da das zusätzliche Handling der Befestigungselemente und Dichtungen wegfällt. Daraus ergibt sich überdies ein Kostenvorteil.This object is achieved in that the at least one fastening element, the at least one sealing element and the collar region are non-releasably firmly connected components of the sleeve. This results in the advantage that the elements can not be forgotten during assembly, which is associated with increased safety and operating safety. In addition, the logistical effort is significantly lower, since the additional handling of fasteners and seals is eliminated. This also results in a cost advantage.
Mindestens zwei der drei miteinander unlösbar verbundenen Bestandteile können aus unterschiedlichen Materialien bestehen. Damit ist eine optimale Anpassung der Werkstoffeigenschaften an die Einbau- und Betriebsbedingungen möglich.At least two of the three non-detachably connected components may consist of different materials. This makes it possible to optimally adapt the material properties to the installation and operating conditions.
Das Dichtelement kann aus einem flexibleren Werkstoff als die Manschette bestehen, damit Unebenheiten gut ausgeglichen werden, das Befestigungselement kann dagegen aus einem Material mit höherer Elastizität als die Manschette bestehen, damit eine gute Spannwirkung mit hoher Lebensdauer erzielt wird.The sealing member may be made of a more flexible material than the sleeve, so that bumps are well balanced, the fastener, however, may consist of a material with higher elasticity than the sleeve, so that a good clamping effect is achieved with a long service life.
Zweckmäßigerweise können das mindestens eine Befestigungselement und das mindestens eine Dichtelement durch Anspritzen mit der Manschette unlösbar verbunden sein. Damit sind eine Vielzahl von Querschnitten erzielbar, die den Einbau und die Betriebsfestigkeit der Manschetten deutlich verbessern. Die Elemente können schon während des Herstellprozesses der Manschette angebracht werden, was eine deutliche Kostensenkung möglich macht.Conveniently, the at least one fastening element and the at least one sealing element can be connected inextricably by injection with the sleeve. Thus, a variety of cross sections can be achieved, which significantly improve the installation and durability of the sleeves. The elements can be attached during the manufacturing process of the cuff, which makes a significant cost reduction possible.
