Abstract

Brake booster for vehicle has brake adapter (8) and pressure rod which transfers the pedal pressure to the brake booster. An acoustic element (13), e.g. nonwoven cotton, plastic foam, is fixed at the outer wall of the booster housing (6) which is turned to the passenger compartment (1).

Description

Die Erfindung betrifft einen Bremskraftverstärker an Kraftfahrzeugen, bestehend aus einem Verstärkergehäuse, einem an diesem angeflanschten Bremsadapter und einer Druckstange, die ihrerseits durch die Spritzwand der Fahrgastzelle hindurch den Fußhebeldruck auf den Bremskraftverstärker überträgt.The invention relates to a brake booster on motor vehicles, consisting of an amplifier housing, a brake adapter flanged to this and one Push rod, which in turn through the bulkhead of the passenger compartment Transfers foot pedal pressure to the brake booster.

Es ist allgemein bekannt, Bremskraftverstärker mit Hilfe eines Adapters an der Spritzwand der Fahrgastzelle fest anzuordnen, wobei die Verbindung zwischen dem im Motorraum angeordneten Bremskraftverstärker und dem in der Fahrgastzelle angeordneten Bremshebel über eine Druckstange realisiert wird. Im Motorraum erzeugte Schallwellen dringen durch die für die Montage des Bremskraftverstärkers vorgesehene Öffnung in die Fahrgastzelle ein und werden durch die Fahrgäste als unangenehm empfunden.It is generally known to use an adapter on the brake booster Arrange the bulkhead of the passenger compartment firmly, the connection between the in Engine compartment arranged brake booster and that in the passenger compartment arranged brake lever is realized via a push rod. Generated in the engine compartment Sound waves penetrate through those intended for the assembly of the brake booster Opening into the passenger compartment and are considered uncomfortable by the passengers felt.

Um diesem Mißstand zu begegnen, ist es aus der DE 38 03 958 C2 und der DE 197 34 290 A1 bekannt, im Bereich der Druckstange eine Abdichtung in Form eines Faltenbalges vorzusehen, der seinerseits das Eindringen eines bestimmten Teiles der störenden Schallwellen in die Fahrgastzelle unterbindet.To counteract this maladministration, it is from DE 38 03 958 C2 and DE 197 34 290 A1 known, a seal in the form of a push rod To provide bellows, which in turn prevents the penetration of a certain part of the disturbing sound waves in the passenger compartment.

Sicherlich ist mit dieser Maßnahme schon ein merklicher Erfolg zu verzeichnen. Unabhängig davon ist festzustellen, dass nach wie vor im Motorraum erzeugte Schallwellen in die Fahrgastzelle eindringen. Hier setzt die nachfolgend beschriebene Erfindung an.This measure is sure to be a noticeable success. Regardless of this, it should be noted that still generated in the engine compartment Sound waves penetrate into the passenger compartment. Here is the one described below Invention.

Aufgabe der Erfindung ist es, in Verbesserung des Standes der Technik den Schalldämmungs- und Schalldämpfungseffekt mit einfachen und kostengünstigen Maßnahmen noch weiter zu erhöhen. The object of the invention is to improve the state of the art Soundproofing and soundproofing effect with simple and inexpensive Measures to increase even further.  

Erfindungsgemäß wird die Aufgabe in Verbindung mit den Merkmalen im Oberbegriff des Anspruchs 1 dadurch gelöst, dass wenigstens an der zur Fahrgastzelle weisenden äußeren Wandung des Verstärkergehäuses ein Akustikelement fest angeordnet ist.According to the invention the task in connection with the features in the preamble of Claim 1 solved in that at least facing the passenger compartment outer wall of the amplifier housing an acoustic element is fixed.

In Ausgestaltung der Erfindung besteht das Akustikelement aus einem akustisch wirksamen Material in Form eines Baumwollfaservlieses, eines Feinvlieses oder eines Kunststoffschaumes. Des Weiteren wird vorgeschlagen das Akustikelement auf die äußere Wandung des Verstärkergehäuses aufzukleben oder mit dieser zu verschrauben.In an embodiment of the invention, the acoustic element consists of an acoustic effective material in the form of a cotton fiber fleece, a fine fleece or Plastic foam. Furthermore, the acoustic element on the Glue or screw the outer wall of the amplifier housing.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is in following described in more detail.

Die einzige Figur zeigt in einer Explosionsdarstellung einen Ausschnitt der Fahrgastzelle 1 und des Motorraums 2 eines Kraftfahrzeugs mit dem Bremskraftverstärker 3, der Spritzwand 4 und dem Fußhebelwerk 5. Wie aus der Zeichnung weiterhin ersichtlich, ist das Verstärkergehäuse 6 des Bremskraftverstärkers 3 gasdicht (Dichtung 7) mit einem angeflanschten Adapter 8 fest verbunden, wobei die Flanschverbindung realisierenden Schraubverbindungen 9 gleichzeitig die feste Verbindung des Verstärkergehäuses 6 mit der Spritzwand 4 und mit dem Fußhebelwerk 5 bewerkstelligen. Die Wirkverbindung zwischen dem Bremskraftverstärker 3 und dem Bremspedal 10 wird bekanntermaßen durch eine Aussparung 11 in der Spritzwand 4 hindurch über eine Druckstange 12 realisiert.The single figure shows an exploded view of a section of the passenger compartment 1 and the engine compartment 2 of a motor vehicle with the brake booster 3 , the bulkhead 4 and the foot pedal mechanism 5 . As can also be seen from the drawing, the booster housing 6 of the brake booster 3 is gas-tight (seal 7 ) with a flange-mounted adapter 8 , the flange connections realizing screw connections 9 simultaneously effecting the firm connection of the booster housing 6 with the bulkhead 4 and with the foot pedal mechanism 5 , The active connection between the brake booster 3 and the brake pedal 10 is known to be realized through a recess 11 in the bulkhead 4 through a push rod 12 .

Es versteht sich für den Fachmann von selbst, dass diese konkrete Konstellation eine Übertragung von im Motorraum 2 erzeugten Schallwellen in die Fahrgastzelle 1 unterstützt. Demgemäß ist es beabsichtigt, wenigstens an der zur Fahrgastzelle 1 weisenden äußeren Wandung des Verstärkergehäuses 6 ein Akustikelement 13 fest anzuordnen.It goes without saying for the person skilled in the art that this specific constellation supports a transmission of sound waves generated in the engine compartment 2 into the passenger compartment 1 . Accordingly, it is intended to arrange an acoustic element 13 firmly at least on the outer wall of the booster housing 6 facing the passenger compartment 1 .

Dieses Akustikelement 13 besteht in der bevorzugten Ausführungsform aus einem akustisch wirksamen Material, welches seinerseits ein Baumwollfaservlies, ein Feinflies oder ein Kunsstoffschaum sein kann. In the preferred embodiment, this acoustic element 13 consists of an acoustically active material, which in turn can be a cotton fiber fleece, a fine fleece or a plastic foam.

Die feste Verbindung zwischen dem Verstärkergehäuse 6 und dem Akustikelement 13 wird bevorzugt durch Kleben realisiert. Selbstverständlich kann diese aber auch durch eine Schraubverbindung erfolgen.The fixed connection between the amplifier housing 6 and the acoustic element 13 is preferably realized by gluing. Of course, this can also be done by a screw connection.
