Beilagscheibe für einen BremskolbenWasher for a brake piston

Die Erfindung betrifft eine Beilagscheibe zur Verhinderung des Quietschens von einem Bremskolben. Die Erfindung be-• trifft damit eine Beilagscheibe, die am Bremskolben einer Scheibenbremse befestigt wird.The invention relates to a washer for preventing the squeaking of a brake piston. The invention This hits a washer that is attached to the brake piston of a disc brake.

Das Vorsehen von einer kreisförmigen Beilagscheibe am offenen Ende des Bremskolbens dient dazu, da s durch die Bremsbeläge hervorgerufene Quietschgeräusch zu unterdrücken, wenn die Bremsen in Betrieb gesetzt werden.The provision of a circular washer at the open end of the brake piston serves to allow the brake pads to pass through to suppress the squeaking noises caused when the brakes are activated.

Eine herkömmliche Anordnung ist in Figur 1 gezeigt und wird nachfolgend näher beschrieben.A conventional arrangement is shown in Figure 1 and will described in more detail below.

Ziel der Erfindung ist es, die später aufgeführten Nachteile der herkömmlichen Befestigung der Beilagscheibe zu beseitigen und gleichzeitig eine solche Beilagscheibe zu schaffen, die sicher an Ort und Stelle angebracht und während des Bremsens nicht versetzt werden kann.The aim of the invention is to overcome the disadvantages of to eliminate conventional fastening of the washer and at the same time to create such a washer that securely attached in place and cannot be moved while braking.

Ausführungsformen der Erfindung werden anhand der Zeichnung nachfolgend näher erläutert. Es zeigenEmbodiments of the invention are based on the drawing explained in more detail below. Show it

Figur 1 eine geschnittene Ansicht von einer herkömmlichen an einem Bremskolben befestigten Beilagscheibe.Figure 1 is a sectional view of a conventional washer attached to a brake piston.

Figur 2 eine Draufsicht auf eine erfindungsgemäß aufgebaute Beilagscheibe.FIG. 2 shows a plan view of a washer constructed according to the invention.

Figur 3 eine geschnittene Ansicht von einer am Bremskolben befestigten Beilagscheibe gemäß Figur 2.FIG. 3 shows a sectional view of a washer according to FIG. 2 fastened to the brake piston.

Figur 4 eine Draufsicht auf eine andere Ausführungsform einer erfindungsgemäß aufgebauten Beilagscheibe undFigure 4 is a plan view of another embodiment a washer constructed according to the invention and

Figur 5 eine geschnittene Ansicht von der am Bremskolben befestigten Beilagscheibe nach Figur 4.FIG. 5 shows a sectional view of the washer according to FIG. 4 fastened to the brake piston.

Wie in Figur 1 gezeigt, erfolgte bislang die Befestigung der Beilagscheibe mittels einer Blattfeder 2, die sich axial von der Scheibe 1 erstreckt und gegen die Innenfläche der Bohrung oder des Zylinders 4 in einem Kolben 3 andrückt. Diese herkömmliche Befestigung hat jedoch den Nachteil, daß nur die Elastizität der Blattfeder 2 eine befestigende Wirkung ausübt, so daß sich die Beilagschexbe leicht in Radialrichtung verschieben läßt und daher ein sicherer Halt der Beilagscheibe an Ort und Stelle schwierig einzuhalten ist. Darüberhinaus verschiebt sich die Beilagscheibe 1 leicht aufgrund der Bremsdrehmomente und Schwingungen während des Bremsens relativ zum Kolben 3. Um die Verschiebung der Beilagscheibe zu verhindern, muß daher eine spezielle Befestigung vorgesehen werden.As shown in Figure 1, the washer was previously attached by means of a leaf spring 2, which extends axially extends from the disc 1 and presses against the inner surface of the bore or cylinder 4 in a piston 3. However, this conventional fastening has the disadvantage that only the elasticity of the leaf spring 2 has a fastening effect exercises, so that the Beilagschexbe can be easily moved in the radial direction and therefore a secure hold of the Washer is difficult to keep in place. In addition, the washer 1 shifts slightly due to the braking torques and vibrations during braking relative to the piston 3. To the displacement of the washer To prevent this, a special attachment must therefore be provided.

Nach Figuren 2 und 3 umfaßt die Beilagscheibe 1o nach der Erfindung eine kreisförmige Hauptplatte 11,eine Blattfeder 12 und einen an der Hauptplatte 11 ausgebildeten Anschlag 13. Die BeilagscheibeAccording to Figures 2 and 3, the washer comprises 1o according to the invention a circular main plate 11, a leaf spring 12 and one on the Main plate 11 formed stop 13. The washer

909841/0918 - 4 ~909841/0918 - 4 ~

19139341913934

1o wird integral durch Ausstanzen von Federstahlplatten oder dergleichen gebildet. Die Blattfeder 12 ist so gestaltet , daß ihre Seitenkante dem Umfang der Hauptplatte 11 zuweist, um in Radialrichtung die erforderliche Elastizität vorzusehen. Der Anschlag 13 ist so ausgebildet, daß seine abgebogene Kante in Radialrichtung liegt, um in Radialrichtung eine ausreichende Steifigkeit zu erhalten.1o becomes integral by punching out spring steel plates or the like. The leaf spring 12 is designed so that its side edge faces the circumference of the main plate 11, to provide the necessary elasticity in the radial direction. The stop 13 is designed so that its bent edge lies in the radial direction in order to obtain sufficient rigidity in the radial direction.

Wie in Figur 3 gezeigt, ist die vorgenannte Beilagscheibe 1o am Bremskolben befestigt. Eine Außenkante des Anschlags 13 befindet sich in Berührung mit der Innenfläche der Bohrung 4 im Kolben 3. Die Beilagscheibe 1o kann daher sicher angebracht werden und erfährt wegen der Steifigkeit des Anschlags 13 in radialer Richtung keine Verschiebung.As shown in Figure 3, the aforementioned washer 1o is attached to the brake piston. An outer edge of the stop 13 is in contact with the inner surface of the bore 4 in the piston 3. The washer 1o can therefore safely be attached and experiences no displacement in the radial direction because of the rigidity of the stop 13.

Zur Erzielung des vorgenannten Effektes ist es notwendig, wenigstens drei Anschläge vorzusehen, obgleich auch mehr als drei angeordnet werden können. Ferner ist der Abstand zwischen den Anschlägen vorzugsweise gleich.To achieve the aforementioned effect, it is necessary to provide at least three stops, although more can be arranged as three. Furthermore, the distance between the stops is preferably the same.

Wie in Figuren 4 und 5 gezeigt, kann die Blattfeder 12 weggelassen werden, indem man den Anschlägen 13 eine, geeignete Länge verleiht. Wenn die Anschläge 13 ebenfalls als Feder 12 dienen, die gegen die Innenfläche der Bohrung 4 im Kolben drücken, kann die Blattfeder 12 also weggelassen werden.As shown in Figures 4 and 5, the leaf spring 12 can be omitted by giving the stops 13 a suitable length. If the stops 13 also as a spring 12, which press against the inner surface of the bore 4 in the piston, the leaf spring 12 can therefore be omitted will.

Erfindungsgemäß wird daher durch das Vorsehen der Anschläge mit Steifigkeit in radialer Richtung eine genaue Anordnung der Beilagscheibe während des Zusammenbaus erzielt und eine Verschiebung der Beilagscheibe durch die Bremsdrehmomente und Schwingungen während des Bremsvorgangs verhindert.According to the invention, a precise arrangement is therefore achieved by providing the stops with rigidity in the radial direction the washer achieved during assembly and a displacement of the washer by the braking torques and prevents vibrations during braking.
