Abstract
Bremskraftverstärker (1) mit wenigstens einem Verstärkergehäuseteil (2, 3) und einer Öffnung (7), in die ein Dichtungselement (9) aus flexiblem Werkstoff eingesetzt ist, welches Dichtungselement (9) eine Ausnehmung (10) aufweist, in die ein pneumatischer Anschluß (8) insbesondere für die Vakuumversorgung des Bremskraftverstärkers (1) einschiebbar ist, dadurch gekennzeichnet, daß das Dichtungselement (9) eine einstückig daran angeordnete Membran (18) aufweist, die die Ausnehmung (10) des Dichtelementes (9) durch eine etwa rechtwinklig zu der Einschubrichtung vorgesehene Erstreckung verschließt, und dem montagebedingten Einschieben eines pneumatischen Anschluß keinen nennenswerten Widerstand entgegensetzt.Brake booster (1) with at least one booster housing part (2, 3) and an opening (7), in which a sealing element (9) made of flexible material used is, which sealing element (9) has a recess (10), in which a pneumatic connection (8) in particular for the vacuum supply of the brake booster (1) can be inserted, characterized in that the sealing element (9) one piece arranged thereon membrane (18) having the recess (10) of the Sealing element (9) by an approximately perpendicular to the insertion direction intended extension closes, and the assembly-related Inserting a pneumatic connection no significant resistance opposes.
Description
Die Erfindung betrifft einen Bremskraftverstärker für ein Kraftfahrzeug mit den Merkmalen des Oberbegriffs des Patentanspruch 1.The The invention relates to a brake booster for a motor vehicle with the Features of the preamble of claim 1.
Ein
derartiger Bremskraftverstärker
ist beispielsweise aus dem Bremsenhandbuch der Anmelderin, Auflage
9.1*, 1993, Autohaus Verlag GmbH, Ottobrunn bei München, Seite
101,
Im
Rahmen der Reduktion der Fertigungstiefe bei den Produktionsstätten der
Automobilhersteller hat es sich grundsätzlich durchgesetzt, daß diese
einen vormontierten Bremskraftverstärker mit daran montierten Anbauteilen
und insbesondere auch einem daran montierten pneumatischen Anschluß von dem
Zulieferbetrieb erhalten. Dabei wird ein ins Freie ragender Stutzen
des pneumatischen Anschlusses üblicherweise
durch eine abdichtende Schutzkappe verschlos sen (
Aufgabe der vorliegenden Erfindung ist es daher, einen Bremskraftverstärker zu schaffen, welcher mit geringem Aufwand sowie erst im Werk des Automobilherstellers komplettierbar, das heißt mit den notwendigen pneumatischen Anschlüssen ausrüstbar ist, wobei der Bremskraftverstärker insbesondere während des Transports dennoch zuverlässig vor Verunreinigung oder unbefugter Manipulation geschützt ist.task Therefore, it is the object of the present invention to provide a brake booster create, which with little effort and only in the factory of the car manufacturer complete, that is can be equipped with the necessary pneumatic connections, the brake booster in particular while the transport yet reliable Contamination or unauthorized manipulation.
Diese Aufgabe wird zusammen mit den kennzeichnenden Merkmalen des Patentanspruch 1 dadurch gelöst, daß der Bremskraftverstärker ein Dichtungselement aufweist, welches eine einstückig daran angeordnete Membran aufweist, die die Durchgangsöffnung des Dichtelementes verschließt, und einem Einschieben eines pneumatischen Anschluß keinen nennenswerten Widerstand entgegensetzt.These Task is together with the characterizing features of the claim 1 solved by that the Brake booster a sealing member which integrally therewith having arranged membrane which closes the passage opening of the sealing element, and insertion of a pneumatic connection no significant resistance opposes.
Die erfindungsgemäße Lösung zeichnet insbesondere durch eine Vereinfachung des Montageprozeß aus, weil gesonderte Verschlußstopfen grundsätzlich nicht erforderlich sind, und somit auch deren Entsorgungsproblematik entfällt. Mit der Erfindung wird schließlich auch ausgeschlossen, daß irgendwelche Fremdkörper oder auch zu entfernende Teile (des Dichtungselementes) vor oder während der Montage des Anschluß in das Innere des Bremskraftverstärkers gelangen können, wo diese Teile eine Funktionsstörung hervorrufen könnten. Die erfindungsgemäße Lösung zeichnet sich somit auch durch Vorteile im Rahmen der FMEA (FMEA = Fehler-Möglichkeits-Einfluß-Analyse) aus.The inventive solution draws in particular by simplifying the assembly process, because Separate plugs basically not are required, and thus their disposal problem is eliminated. With The invention finally becomes also excluded that any foreign body or parts to be removed (of the sealing element) before or during the Assembly of the connection in the interior of the brake booster can reach, where these parts malfunction could cause. The solution according to the invention is characterized thus also by advantages in the context of the FMEA (FMEA = error possibility influence analysis) out.
Weitere Einzelheiten der Erfindung gehen aus Unteransprüchen im Zusammenhang mit der Beschreibung und der Zeichnung hervor. Die Erfindung wird nachstehend anhand der Zeichnung, welche ein bevorzugtes Ausführungsbeispiel zeigt, näher beschrieben.
