Scheibenbremse mit SchwimmsattelDisc brake with floating caliper
Die Erfindung betrifft eine Scheibenbremse mit sog. Schwimmsattel ,der durch Führungszapfen geführt wird, die parallel zur Achse der Bremsscheibe in Ausschnitten von Armen eines Bremsenhalters gelagert sind und mit an beiden Seiten der Bremsscheibe angeordneten Bremsplatten, deren Ausschnitte von den Führungszapfen durchragt werden.The invention relates to a disc brake with a so-called floating caliper, which is guided by guide pins that are parallel are mounted to the axis of the brake disc in sections of arms of a brake holder and with on both sides of the Brake disc arranged brake plates, the cutouts of which are penetrated by the guide pins.
Bei bekannten Scheibenbremsen dieser Art wird die Umfangsbremskraft zumindest teilweise über Führungszapfen übertragen, welche entsprechend stark dimensioniert werdenIn known disc brakes of this type, the circumferential braking force at least partially transferred via guide pins, which are dimensioned accordingly strong

müssen, wobei ihr Vorschub bei einem größeren Hub des Bremssattels verschlechtert wird.must, their advance is worsened with a larger stroke of the brake caliper.
Bei anderen bekannten Scheibenbremsen wird die auf den konvexen Stützflächen der Arme eines Halters wirkende Umfangsbremskraft vom Sattel aufgenommen. Ein Nachteil liegt in dem verlängerten Hub des Bremspedals, weil außer der Verschiebebewegung sich der Bremssattel noch dreht. Ein weiterer Nachteil der bekannten Scheibenbremsen ist ihr ungenügendes Ausrücken nach dem Bremsen. Auch bei Anwendung von elastischen O-Ringen zwischen den Augen des Sattels und den Stirnflächen der Führungszapfen wird nach Zusetzen der Lücke zwischen diesen Teilen die gewünschte Ausrückbewegung erschwert oder unmöglich. Ein anderer Nachteil ist der verhältnismäßig komplizierte Austausch der Bremsbeläge. Da die Platten mit ihrem Belag radial ausgebaut werden, muß der Sattel abgehoben bzw. geöffnet werden. Dazu muß wenigstens ein Führungszapfen entsichert und ausgeschoben werden, was bei einer radialen Vorspannung in der Lagerung der Führungszapfen schwierig ist.In other known disc brakes, the one acting on the convex support surfaces of the arms of a holder Circumferential braking force absorbed by the saddle. A disadvantage is the longer stroke of the brake pedal, because besides the sliding movement, the brake caliper is still turning. Another disadvantage of the known disc brakes is their insufficient disengagement after braking. Even when using elastic O-rings between the eyes of the The saddle and the end faces of the guide pins will be the desired after adding the gap between these parts Disengagement movement difficult or impossible. Another disadvantage is the relatively complicated replacement of the brake pads. Since the plates are expanded radially with their covering, the saddle must be lifted or opened. In addition at least one guide pin must be unlocked and pushed out, which in the case of a radial preload in the storage of the guide pin is difficult.
Aufgabe der Erfindung ist es, eine Scheibenbremse zu schaffen, deren Einzelteile nicht überdimensioniert sind, die zuverlässig und stets ausreichend weit ausrückt und bei welcher der Austausch der Bremsbeläge auf einfache Weise durchgeführt wird.The object of the invention is to create a disc brake, the individual parts of which are not oversized, which disengages reliably and always sufficiently and in which the replacement of the brake pads is easy Manner is carried out.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Führungszapfen in elastischen Buchsen exzentrisch gelagert sind, die in Lageraugen des Bügels der Bremse drehbar gelagert sind und mit Vorspannung auf die Tragausschnitte der Arme des Halters von der Bremse anliegen, wobei der Einstellausschnitt mit seinem Innenteil denAccording to the invention, this object is achieved in that the guide pins are eccentric in elastic bushings are mounted, which are rotatably mounted in the bearing eyes of the bracket of the brake and with bias on the support cutouts the arms of the holder rest from the brake, the adjustment cutout with its inner part the

Die Arme des Halters der Bremse sind in Berührung mit der Kontaktfläche des Bremsbelags, die dann durch die Tragausschnitte der Arme des Halters der Bremse und die Einstellausschnitte unterbrochen ist, welche in Berührung mit Führungszapfen stehen. Wenigstens die elastischen Buchsen sind an der Seite der Betätigung der Bremse mit elastischen Stirnen versehen, die zwischen den Stirnflächen der Lageraugen und den Köpfen der Führungszapfen angeordnet sind. Die elastischen Buchsen sind mit den Führungszapfen undrehbar verbunden. Die Führungszapfen sind an der von der Bremsbetätigung abgewandten Seite mit eingesetzten Stiften versehen, deren Achsen senkrecht zu den Achsen der Führungszapfen sind und die in Nuten einfallen, die in Stirnflächen der Lageraugen des Bügels der Bremse angeordnet sind. Die Tragausschnitte der Arme des Halters der Bremse sind mit Vorteil in V-Form.Guide pin protrudes. The arms of the brake holder are in contact with the contact surface of the brake pad, which is then interrupted by the support cutouts of the arms of the brake holder and the adjustment cutouts, which are in contact with guide pins. At least the elastic bushings are provided with elastic foreheads on the side of the actuation of the brake, which between the end faces of the bearing eyes and the heads of the guide pins are arranged. The elastic bushings are with the guide pin non-rotatably connected. The guide pins are provided with inserted pins on the side facing away from the brake actuation, the axes of which are perpendicular to the The axes of the guide pins are and fall into grooves in the end faces of the bearing eyes of the bracket of the brake are arranged. The support cutouts of the arms of the brake holder are advantageously in a V shape.
Ein Ausführungsbeispiel der erfindungsgemäßen Scheibenbremse wird im folgenden anhand der Zeichnung im einzelnen beschrieben. Es zeigen:An embodiment of the disc brake according to the invention is described in detail below with reference to the drawing described. Show it:

Ein Bügel 1 umgreift die Bremsscheibe 2 und weist in angeformten Lageraugen 3 bis 6 gelagerte, exzentrische, elastische Buchsen 7 bis 10 auf, die z. B. durch Vulkanisation mit zwei Führungszapfen 11 und 12 fest verbunden sind. Die beiden Buchsen 8 und 9 an der Betätigungsseite haben elasti-A bracket 1 surrounds the brake disk 2 and has eccentric, elastic ones mounted in molded bearing eyes 3 to 6 Sockets 7 to 10, the z.

sehe Kragen 13 und 14, die sich an Stirnanschlägen an den Führungszapfen 11, 12 abstützen. Die Stirnanschläge sind beim dargestellten Ausführungsbeispiel durch Köpfe 15, 16 der Führungszapfen gebildet. Gegen Ausschieben sind die Führungszapfen 11 und 12 durch Stifte 17 und 18 gesichert, die in Kerben 19 und 20 der Lageraugen 3 und 6 des Bremsbügels 1 eingesteckt sind.see collars 13 and 14, which are at the end stops support the guide pin 11, 12. The front stops are in the illustrated embodiment by heads 15, 16 of the guide pin formed. Against pushing out the guide pins 11 and 12 are secured by pins 17 and 18, which are in notches 19 and 20 of the bearing eyes 3 and 6 of the brake lever 1 are inserted.
Die Führungszapfen 11, 12 sind in bevorzugt V-förmigen Tragausschnitten 21 in Armen 22, 23 eines Bremsenhalters 2-4- geführt. Die Platten mit den Bremsbelägen 25, 26 stützen sich in Tangentialrichtung direkt mit ihren Berührungsflächen 27 auf den Armen 22, 23 des Halters 24 ab und sind radial in beiden Richtungen durch Einstellausschnitte 28 auf den Führungszapfen 11, 12 fixiert. Die Betätigung der Bremse geschieht durch einen Kolben 29, der durch einen Ring 30 abgedichtet ist.The guide pins 11, 12 are preferably V-shaped Carrying cutouts 21 in arms 22, 23 of a brake holder 2-4- out. Support the plates with the brake pads 25, 26 in the tangential direction directly with their contact surfaces 27 on the arms 22, 23 of the holder 24 and are fixed radially in both directions by adjusting cutouts 28 on the guide pins 11, 12. The operation of the Braking is done by a piston 29 which is sealed by a ring 30.
Beim Bremsen drückt der Kolben 29 die Platte mit dem Bremsbelag 26 an die Bremsscheibe 2. Durch die Reaktion wird der Bügel 1 der Bremse in der umgekehrten Bewegungsrichtung des Kolbens 29 bewegt und drückt die Platte mit dem Bremsbelag 25 gegen die andere Seite der Bremsscheibe 2. Diese Bewegung des Bügels 1 wird durch Zusammendrücken der elastischen Kragen 13, 14 der Buchsen 8, 9 ermöglicht, ohne daß sich die Führungszapfen 11, 12 in den Tragausschnitten 21 der Arme 22, 23 des Halters 24 bewegen, weil die Exzentrizität der Öffnung der elastischen Buchsen 7 bis 10 in den Lageraugen 3 bis 6 so gewählt wird, daß die Führungszapfen 11, 12 elastisch gegen die Tragausschnitte 21 gedrückt werden und durch eine bestimmte Kraft gegen Verschiebung gesichert sind. Nach dem Abbremsen federn die elastischen Kragen 13, 14 zurück und drücken den Bügel 1 in die Ursprung-When braking, the piston 29 presses the plate with the brake lining 26 against the brake disc 2. The reaction becomes the Bracket 1 of the brake moves in the opposite direction of movement of the piston 29 and presses the plate with the brake lining 25 against the other side of the brake disc 2. This movement of the bracket 1 is made by compressing the elastic Collar 13, 14 of the sockets 8, 9 allows without the guide pins 11, 12 in the support cutouts 21 of the arms 22, 23 of the holder 24 move because the eccentricity of the opening of the elastic bushings 7-10 in the Bearing eyes 3 to 6 is chosen so that the guide pin 11, 12 are pressed elastically against the support cutouts 21 and secured against displacement by a certain force are. After braking, the elastic collars 13, 14 spring back and press the bracket 1 into the original
liehe gelöste Lage ab. Erst bei einer größeren Abnutzung der Bremsbeläge 26, 27 wird die notwendige Bewegung des Bügels 1 größer, als die Zusammendrückung der elastischen Kragen 15, 14- und es kommt zur Verschiebung der Führungszapfen 11, 12 in den Tragausschnitten 21 der Arme 22, 23. Die Rückbewegung des Bügels 1 nach einer Abbremsung wird jedoch nur durch Abfederung der elastischen Kragen 13, 14-hervorgerufen und es wird nur ein kleines Spiel zum Lösen der Bremsscheibe eingestellt, so daß die Vorrichtung das nötige Spiel zwischen den Bremsbelägen 25, 26 und der Bremsscheibe 2 selbsttätig einstellt.borrowed solved situation. Only when there is greater wear and tear the brake pads 26, 27, the necessary movement of the bracket 1 is greater than the compression of the elastic Collars 15, 14 - and the guide pins 11, 12 are displaced in the support cutouts 21 of the arms 22, 23. The return movement of the bracket 1 after braking is only caused by the cushioning of the elastic collars 13, 14 and only a small amount of play is set to loosen the brake disc so that the device does necessary play between the brake pads 25, 26 and the brake disc 2 automatically adjusts.
Die Umfangskräfte, welche beim Bremsen auf die Platten mit den Bremsbelägen 25, 26 einwirken, werden direkt durch die Berührungsflächen 27 in die Arme 22, 25 des Halters 24 der Bremse übertragen und beanspruchen daher weder den Bügel 1 noch die Führungszapfen 11, 12, so daß diese relativ schwach dimensioniert werden können.The circumferential forces that act on the plates when braking act with the brake pads 25, 26, are directly through the contact surfaces 27 in the arms 22, 25 of the Transfer the holder 24 of the brake and therefore require neither the bracket 1 nor the guide pins 11, 12, so that these can be dimensioned relatively weak.
Die Tragausschnitte 21 in den Armen 22, 23 des Halters 24· haben mit den Führungszapfen 11, 12 nur eine Geradenberührung unter dem elastischen Druck, so daß Verschiebungen auch bei einer beträchtlichen Korrosion der beiden sich berührenden Elemente erfolgen .können.The support cutouts 21 in the arms 22, 23 of the holder 24 have only a straight line contact under the elastic pressure with the guide pins 11, 12, so that displacements can also take place in the event of considerable corrosion of the two elements in contact.
Besonders einfach und schnell können die Bremsbeläge 25, 26 beim Gegenstand der Erfindung ausgetauscht werden. Die Führungszapfen 11, 12 werden gegen die elastischen Kragen 13, 14- gedruckt und um ISO0 gedreht. Durch Eindrücken der Führungszapfen 11, 12 werden die Stifte 17, 18 aus den Nuten 19, 20 herausgeschoben und durch Drehen um 180° können sie aus den Tragausschnitten 2 entfernt werden. Der Bügel 1 kann dann mit den Führungszapfen 11, 12 undThe brake linings 25, 26 in the subject matter of the invention can be exchanged particularly easily and quickly. The guide pins 11, 12 are pressed against the elastic collars 13, 14- and rotated by ISO 0. By pressing in the guide pins 11, 12, the pins 17, 18 are pushed out of the grooves 19, 20 and they can be removed from the support cutouts 2 by rotating them through 180 °. The bracket 1 can then with the guide pins 11, 12 and
der Platte mit den Bremsbelägen 25, 26 aus dem Halter 24 in radialer Richtung ausgebaut werden. Durch Verdrehen der Führungszapfen 11, 12 in die ursprüngliche Lage lösen sich die Platten mit den Bremsbelägen 25, 26, so daß man sie herausnehmen und durch neue ersetzen kann. Die Rückmontage des Bügels 1 wird dann analog durchgeführt. Das leichte Drehen der elastischen Buchsen 7 bis 10 in den Lageraugen 3 bis 6 kann eventuell durch eine Schicht aus geeignetem Gleitmaterial zwischen dem Gummi und dem Metall gesichert werden.the plate with the brake linings 25, 26 from the holder 24 be expanded in the radial direction. By turning the guide pins 11, 12 into the original position, they are released the plates with the brake pads 25, 26 so that you can take them out and can replace it with new ones. The reassembly of the bracket 1 is then carried out in the same way. The easy turning the elastic bushings 7 to 10 in the bearing eyes 3 to 6 can possibly be covered by a layer of suitable Sliding material can be secured between the rubber and the metal.
Die leichte und schnelle Demontage und die Montage der Bremse hat eine Bedeutung nicht nur beim Austausch des Belags, sondern auch bei der Kontrolle des Zustandes der Bremse und beim Austausch der Dichtungselemente·The easy and quick disassembly and assembly of the brake is important not only when replacing the pad, but also when checking the condition of the brake and when replacing the sealing elements
Die relativ großen Abmessungen der elastischen Buchsen 7 bis 10 und der angeformten elastischen Kragen 13, 14 und die günstige Art ihrer Beanspruchung durch Vulkanisation an den Pührungszapfen 11, 12 gewährleistet eine große Akkumulation der Deformationsarbeit und dadurch eine federnde Wirkung auch bei schwankenden Eigenschaften des Gummis.The relatively large dimensions of the elastic bushings 7 to 10 and the molded elastic collar 13, 14 and the favorable nature of their stress by vulcanization on the guide pins 11, 12 ensures a large Accumulation of the work of deformation and thus a resilient effect even with fluctuating properties of the Rubbers.
Die Art der Abstützung der Platten mit den Bremsbelägen 25, 26 auf den Armen 22, 23 des Halters 24 außerhalb des Umfangs der Bremsscheibe wird dadurch ermöglicht, daß die Tragausschnitte 21 in Umfangsrichtung in Richtung zur Mitte der Bremse offen sind und ermöglicht die maximale Ausnutzung der Fläche für den Bremsbelag. Die Platten können eine einfache, technologisch vorteilhafte Form haben.The type of support of the plates with the brake pads 25, 26 on the arms 22, 23 of the holder 24 outside the The circumference of the brake disc is made possible by the fact that the support cutouts 21 in the circumferential direction in the direction of The middle of the brake are open and allows the maximum use of the area for the brake pad. The panels can have a simple, technologically advantageous form.
