Abstract
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, dadurch gekennzeichnet, dass wenigstens an der zur Fahrgastzelle (1) weisenden äußeren Wandung des Verstärkergehäuses (6) ein Akustikelement (13) fest angeordnet ist, wobei das Akustikelement (13) aus einem akustisch wirksamen Material in Form eines Baumwollfaservlieses oder eines Feinvlieses besteht und lediglich auf die äußere Wandung des Verstärkergehäuses (6) aufgeklebt oder mit dieser verschraubt ist.Brake booster on Motor vehicles, consisting of an amplifier housing, one flanged to this Brake adapter and a push rod, which in turn through the bulkhead the passenger compartment transmits the Fußhebeldruck on the brake booster, thereby in that at least on the outer side facing the passenger compartment (1) the amplifier housing (6) an acoustic element (13) is fixedly arranged, wherein the acoustic element (13) made of an acoustically effective material in the form of a cotton fiber fleece or a fine fleece and only on the outer wall the amplifier housing (6) glued or screwed to it.
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 The invention relates to a brake booster on motor vehicles, consisting from an amplifier housing, a on this flanged brake adapter and a push rod, the in turn through the bulkhead of the passenger compartment through the Fußhebeldruck transfers 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 well known, brake booster with the help of an adapter to be fixed to the bulkhead of the passenger compartment, with the connection between the arranged in the engine compartment brake booster and in the passenger compartment arranged brake lever over a push rod is realized. Sound waves generated in the engine compartment penetrate through the for the assembly of the brake booster provided opening into the passenger compartment and are used by the passengers as uncomfortable.

Sicherlich ist mit vorstehenden Maßnahmen 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.Definitely is already with the above measures a noticeable success. Regardless, it should be noted that still generated in the engine compartment sound waves in the passenger compartment penetration. This is where the invention described below begins.
Aufgabe der Erfindung ist es, in Verbesserung des Standes der Technik den Schalldämmungs- und Schalldämpfungseffekt mit einfachen und kostengünstigen Maßnahmen noch weiter zu erhöhen.task The invention is to improve the prior art the Soundproofing and Silencing effect with simple and inexpensive activities even further increase.
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. Ferner besteht das Akustikelement aus einem akustisch wirksamen Material in Form eines Baumwollfaservlieses oder eines Feinvlieses. Des Weiteren ist vorgesehen, dass das Akustikelement auf die äußere Wandung des Verstärkergehäuses aufgeklebt oder mit dieser verschraubt ist.According to the invention Task in conjunction with the features in the preamble of the claim 1 solved by that at least on the outer wall facing the passenger compartment of the amplifier housing Acoustic element is fixed. Furthermore, there is the acoustic element from an acoustically effective material in the form of a cotton fiber fleece or a fine fleece. Furthermore, it is provided that the acoustic element on the outer wall glued on the amplifier housing or screwed to it.
