Abstract
Description
Die Erfindung betrifft eine vorteilhafte Weiterbildung eines Geräuschdämpfers für Scheibenbremsen gemäß Patentanmeldung P 40 21 567.The invention relates to an advantageous development of a Noise damper for disc brakes according to patent application P 40 21 567.
In der Patentanmeldung P 40 21 567 wurde bereits vorgeschlagen, Bremsgeräusche, insbesondere Quietschen, mittels eines Geräuschdämpfers zu unterdrücken. Der Geräuschdämpfer besteht aus einem federnden Element, das außerhalb des Bremssattels verankert ist und eine Reibfläche aufweist, die gegen den Bremssattel gedrückt wird. Da der Geräuschdämpfer außerhalb des Bremssattels verankert ist, bleibt seine Reibfläche im wesentlichen unbeweglich, während der schwingende Bremssattel an der Reibfläche reibt.In the patent application P 40 21 567 was already suggested braking noises, especially squeaking, suppress with a silencer. The Muffler consists of a resilient element that is anchored outside the caliper and a friction surface has that is pressed against the caliper. Since the Muffler is anchored outside the brake caliper, its friction surface remains essentially immobile while the vibrating brake caliper rubs against the friction surface.
Die Befestigung des Geräuschdämpfers außerhalb der Bremse verursacht jedoch einen erheblichen Aufwand. Unbefriedigend ist vor allem, daß dazu Modifikationen am Fahrzeug erforderlich sind und daß der Geräuschdämpfer separat montiert werden muß.The mounting of the silencer outside the brake however, causes considerable effort. Unsatisfactory is, above all, that modifications to the vehicle are required and that the silencer is separate must be installed.
Daraus ergibt sich die Aufgabe, einen vorgeschlagenen Geräuschdämpfer zu verbessern, so daß er direkt an der Bremse befestigt und die geräuschgedämpfte Bremse als vormontierte Einheit am Fahrzeug eingebaut werden kann.Hence the task of a proposed one Improve muffler so that it is directly on the Brake attached and the silenced brake as pre-assembled unit can be installed on the vehicle.
Die Lösung der Aufgabe ergibt sich aus dem kennzeichnenden Teil des Patentanspruchs 1 und besteht im Prinzip darin, daß der am Bremsengehäuse befestigte Geräuschdämpfer mit einer Zusatzmasse versehen ist, die am Bremsengehäuse federnd anliegt. Aufgrund ihrer Trägheit ermöglicht die Zusatzmasse eine reibende Relativbewegung zwischen der Anlagefläche des Geräuschdämpfers und dem Bremsengehäuse.The solution to the problem arises from the characteristic Part of claim 1 and consists in principle in that the muffler attached to the brake housing with a Additional mass is provided, which is resilient on the brake housing is present. Due to its inertia, the additional mass allows a rubbing relative movement between the contact surface of the Muffler and the brake housing.
In einer bevorzugten Ausgestaltungsform der Erfindung nach Anspruch 2 ist der Geräuschdämpfer an einem Führungsbolzen einer Schwimmsattel-Teilbelagscheibenbremse befestigt. Diese Befestigung erfordert lediglich einen modifizierten Führungsbolzen, während die Bremsengehäuse einer laufenden Serie ansonsten unverändert übernommen werden können. Dadurch werden Werkzeugkosten eingespart. Außerdem ist ein Nachrüsten herkömmlicher Bremsen mit dem erfindungsgemäßen Geräuschdämpfer möglich. Weitere vorteilhafte Ausgestaltungsmerkmale werden in den Unteransprüchen 3 und 4 offenbart.In a preferred embodiment of the invention Claim 2 is the silencer on a guide pin a floating caliper partial brake disc brake attached. These Attachment only requires a modified one Guide bolt while the brake housing is running Series can otherwise be adopted unchanged. This saves tool costs. In addition, is a Retrofitting conventional brakes with the invention Muffler possible. More beneficial Design features are in subclaims 3 and 4 disclosed.
Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand einer Zeichnung näher erläutert. Die einzige Figur zeigt eine teilweise geschnittene Seitenansicht einer Schwimmsattel-Teilbelagscheibenbremse mit einem erfindungsgemäßen Geräuschdämpfer.An embodiment of the invention is as follows explained in more detail using a drawing. The only figure shows a partially sectioned side view of a Floating caliper partial brake disc brake with one silencer according to the invention.
Die dargestellte Teilbelagscheibenbremse weist einen Schwimmsattel 1 mit einem Bremskolben 2 und zwei Bremsbacken 3, 4 auf, die zum Andruck an eine Bremsscheibe 5 bestimmt sind. Der Schwimmsattel 1 ist mittels zweier Bolzenführungen an einem Bremsträger 6 verschiebbar geführt. Eine der beiden Bolzenführungen ist in der Zeichnung erkennbar. In einer Gewindebohrung 7 des Bremsträgers 6 ist ein Gewinde 8 eines Führungsbolzens 9 eingeschraubt, auf dem ein mit dem Schwimmsattel 1 verbundenes Bushingauge 10 gleitet, das mit einem Bushing 11 aus elastischem Material versehen ist.The partial brake disk brake shown has a floating caliper 1 with a brake piston 2 and two brake shoes 3 , 4 , which are intended to be pressed against a brake disk 5 . The floating caliper 1 is slidably guided on a brake carrier 6 by means of two bolt guides. One of the two bolt guides can be seen in the drawing. A thread 8 of a guide pin 9 is screwed into a threaded bore 7 of the brake carrier 6 , on which a bushing eye 10 connected to the floating caliper 1 , which is provided with a bushing 11 made of elastic material, slides.
Der Führungsbolzen 9 ist an seinem dem Bremsträger 6 abgewandten Endabschnitt mit einer umlaufenden Ringnut 12 versehen, in der das eine Ende 17 einer zu einem Geräuschdämpfer 14 gehörenden Drahtfeder 13 festgeklemmt ist. Zum Geräuschdämpfer 14 gehört weiterhin eine Zusatzmasse 15 mit einem zylindrischen Grundkörper, der auf seiner einen Axialseite in einen Kegel 19 übergeht und auf seiner anderen Axialseite einen zylindrischen Vorsprung 16 aufweist, um den das andere Ende 18 der Drahtfeder 13 geschlungen ist. Der Führungsbolzen 9 weist in seinem Endabschnitt eine axiale Öffnung 20 mit sechseckigem Querschnitt auf, die ursprünglich zur Aufnahme eines Schraubenschlüssels bestimmt ist. Die Zusatzmasse 15 wird nun mittels der Feder 13 axial gegen das Ende des Führungsbolzens 9 gedrückt, so daß sich die Spitze des Kegels 19 in die Öffnung 20 hinein erstreckt und der Kegelmantel am äußeren Rand der Öffnung 20 anliegt. Diese einfache Befestigung erlaubt einerseits Relativbewegungen zwischen Bremse und Zusatzmasse 15 und verhindert andererseits das Herausfallen der Zusatzmasse 15.The guide pin 9 is provided on its end section facing away from the brake carrier 6 with a circumferential annular groove 12 , in which the one end 17 of a wire spring 13 belonging to a noise damper 14 is clamped. The muffler 14 also includes an additional mass 15 with a cylindrical base body which merges into a cone 19 on one axial side and has a cylindrical projection 16 on its other axial side, around which the other end 18 of the wire spring 13 is wound. The guide pin 9 has in its end section an axial opening 20 with a hexagonal cross section, which was originally intended for receiving a wrench. The additional mass 15 is now pressed axially against the end of the guide pin 9 by means of the spring 13 , so that the tip of the cone 19 extends into the opening 20 and the cone jacket lies against the outer edge of the opening 20 . This simple fastening allows, on the one hand, relative movements between the brake and additional mass 15 and, on the other hand, prevents the additional mass 15 from falling out.
