Die Erfindung bezieht sich auf eine Teilbelagscheibenbremse, insbesondere für Kraftfahrzeuge, bei welcher die Bremsscheibe auf einem mittleren Radius mittels seitlicher Tragarme am Fahrzeugrad befestigt ist und mit Reibbelägen zusammenarbeitet, die auf deren beiden Seiten angeordnet und der Wirkung eines Zuspannzylinders ausgesetzt sind, welcher zur axialen Verstellbarkeit quer zur Scheibe an einem auf entsprechenden Führungsachsen verschieblichen Bügel befestigt ist.The invention relates to a partially lined disc brake, in particular for motor vehicles which attaches the brake disc to the vehicle wheel on a medium radius by means of lateral support arms is and cooperates with friction linings, which are arranged on both sides and the effect a clamping cylinder are exposed, which for axial adjustability transversely to the disc on a corresponding guide axes sliding bracket is attached.

Bei einer bekannten Teilbelagscheibenbremse dieser Bauart (deutsche Auslegeschrift 1 070 048) sind Führungsachsen an dem einen Bremsbelagträger starr befestigt. Sie verschieben sich also bei einer entsprechenden Verstellung dieses Belagträgers innerhalb von Führungsbüchsen, die am stationären Bremsträger angeordnet sind. Die gegenseitige Annäherung beider Belagträger geht bei der bekannten Anordnung so vor sich, daß das durch eine Öffnung in den Zylinder eingeleitete Druckmittel den Kolben verschiebt, was eine entgegengesetzte Verstellung des Zylinders zur Folge hat. Es handelt sich bei der bekannten Bauart darum, die von dem Kolben ausgeübte Kraft auf den Bremsbelagträger zu übertragen, wozu ein zylindrischer Ansatz des Kolbens auf einen Bügel einwirkt, dessen beide Enden an den Führungsachsen angreifen und dieselben unter Mitnahme des Bremsbelagträgers verstellen. Die Führungsachsen dienen dabei außer zur Führung auch zur Aufnahme der Anpreßkräfte.In a known partially lined disc brake of this type (German Auslegeschrift 1 070 048) are Guide axles rigidly attached to the one brake lining carrier. So they shift when there is a corresponding one Adjustment of this lining carrier within guide bushes on the stationary brake carrier are arranged. The mutual approach of the two lining carriers is possible with the known arrangement in such a way that the pressure medium introduced into the cylinder through an opening moves the piston, which results in an opposite adjustment of the cylinder. It is of the known type about transmitting the force exerted by the piston to the brake lining carrier, including a cylindrical one Approach of the piston acts on a bracket, both ends of which engage the guide axes and adjust the same while taking along the brake lining. The guide axes serve besides for guidance and for absorbing the contact pressure.

Weiterhin ist eine Teilbelagscheibenbremse bekannt (französische Patentschrift 960 072),. bei welcher ein verhältnismäßig kompliziertes Gelenksystem zur Halterung des Zuspannzylinders verwendet wird. Dabei ist ein Bügel vorgesehen, der an einer Wange gelenkig angeordnet ist. Schließlich ist noch eine Bauart bekannt, bei welcher die beiden Bremsbeläge von zwei Backen getragen werden, die um eine gemeinsame Achse schwenkbar sind.Furthermore, a partially lined disc brake is known (French patent specification 960 072). at which one relatively complicated joint system is used to hold the brake application cylinder. Included a bracket is provided which is articulated on one cheek. Finally, there is one more design known, in which the two brake pads are carried by two jaws around a common Axis are pivotable.

Die Aufgabe der Erfindung besteht darin, eine Teilbelagscheibenbremse der eingangs erwähnten Bauart zu schaffen, die einen geringen Raumbedarf aufweist, einfach ausgebildet ist, wenig Einzelteile besitzt und insbesondere eine gute Anpassung an die bleibenden oder vorübergehenden Verformungen der jeweiligen Bremsscheibe gewährleistet. Weiterhin soll ein geringes Bremsspiel sichergestellt sein.The object of the invention is to provide a partially lined disc brake of the type mentioned at the beginning To create a design that has a small footprint, is simple, has few items and especially good adaptation to the permanent or temporary deformations of the respective brake disc guaranteed. Furthermore, a small brake clearance should be ensured.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die neben den seitlichen Tragarmen der Scheibe befindlichen Bremsbeläge von mit dem Bügel fest verbundenen Druckstücken abgestützt sind, während die gegenüberliegenden Bremsbeläge der Wirkung eines im Zuspannzylinder beweglichen Kolbens Teilbelagscheibenbremse, insbesondere für
KraftfahrzeugeThis object is achieved according to the invention in that the brake linings located next to the lateral support arms of the disc are supported by pressure pieces firmly connected to the bracket, while the opposite brake linings have the effect of a piston movable in the brake application cylinder, in particular for

Infolge der erfindungsgemäßen Ausbildung der Teilbelagscheibenbremse wird die gesamte, von beiden Seiten auf die Bremsscheibe aufgebrachte Druckkraft vom Bügel aufgenommen, da die Bremsbeläge einerseits unmittelbar an demselben und andererseits am Kolben des Zuspannzylinders angebracht sind. Die am Fahrzeugrahmen befestigten Führungsachsen dienen dabei lediglich der Verstellbarkeit des Bügels, ohne irgendwelche Zugkräfte übertragen zu müssen. Die Erfindung ist im folgenden an Hand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigtAs a result of the design of the partially lined disc brake according to the invention, the entire, of both Sides applied to the brake disc compressive force absorbed by the bracket, as the brake pads are attached on the one hand directly to the same and on the other hand to the piston of the brake application cylinder. The guide axles attached to the vehicle frame only serve to adjust the bracket, without having to transmit any tensile forces. The invention is based on an in the embodiment illustrated in the drawing explained in more detail. It shows

Die Bremsbeläge sind der Wirkung eines Zuspannzylinders ausgesetzt, welcher zur axialen Verstellbarkeit quer zur Bremsscheibe an einem auf entsprechenden Führungsachsen verschieblichen Bügel 1 befestigt ist.for the support arms 5 ', while the brake pads 6 'can consist of one piece. The brake pads are the action of a brake application cylinder exposed, which for axial adjustability transversely to the brake disc on a corresponding Guide axes displaceable bracket 1 is attached.

Nach der Erfindung sind die neben den seitlichen Tragarmen 5' der Bremsscheibe 5 befindlichen Bremsbeläge 6 von mit dem Bügel 1 fest verbundenen Druckstücken 8 und 9 abgestützt. Dabei sind die Bremsbeläge 6 mittels Zapfen 23 an den Druckstücken befestigt. Die gegenüberliegenden Bremsbeläge 6' sind der Wirkung eines im Zuspannzylinder 7 beweglichen Kolbens 2 ausgesetzt. Weiterhin ist eine Rückholfeder 10 zwischen dem Bügel 1 und einem mit den gegenüberliegenden Reibbelägen 6' verbundenen Steg 12 vorgesehen.According to the invention, the brake pads located next to the lateral support arms 5 'of the brake disc 5 are 6 supported by pressure pieces 8 and 9 firmly connected to the bracket 1. There are those Brake pads 6 attached to the pressure pieces by means of pins 23. The opposite brake pads 6 'are exposed to the action of a piston 2 movable in the clamping cylinder 7. There is also a return spring 10 between the bracket 1 and a web 12 connected to the opposite friction linings 6 ' intended.

Der Bügel 1 ist dabei senkrecht zur Ebene der Bremsscheibe verschieblich angeordnet, und zwar mit Hilfe von Führungsachsen 3, die an einer mit dem Fahrzeugrahmen fest verbundenen Halterung 4 vorgesehen sind.The bracket 1 is arranged displaceably perpendicular to the plane of the brake disc, namely with With the help of guide axles 3, which are provided on a bracket 4 firmly connected to the vehicle frame are.

Die Verbindung zwischen den Bremsbelägen 6' und dem Steg 12 geschieht mittels Stangen 13.The connection between the brake linings 6 ′ and the web 12 takes place by means of rods 13.

Vorteilhafterweise wirkt die Rückholfeder 10 auf eine Nachstellvorrichtung für das Lüftspiel der Bremsbeläge. Dabei stützt sich eine Stange 17, welche die Achse der Rückholfeder 10 bildet, einerseits gegen den Steg 12 mittels eines Sprengringes 14 und andererseits gegen zwei Anschläge 16 und 18 ab. Der Anschlag 16 ist mit der Stange 17 fest verbunden, während der axialfreie Anschlag 18 sich gegen ein Reibstück 15 abstützt und durch eine Schulter der Stange 17 verschoben werden kann, nachdem diese Schulter die Feder 10 um einen Betrag zusammengedrückt hat, der gleich dem Lüftspiel ist.The return spring 10 advantageously acts on an adjusting device for the clearance of the brake linings. A rod 17, which forms the axis of the return spring 10, is supported against it on the one hand the web 12 by means of a snap ring 14 and on the other hand against two stops 16 and 18 from. The attack 16 is firmly connected to the rod 17, while the axially free stop 18 is against a friction piece 15 is supported and can be moved by a shoulder of the rod 17 after this shoulder the spring 10 has compressed by an amount equal to the clearance.

Vorteilhafterweise sind im Inneren der Führungsachsen 3 Nachstellvorrichtungen vorgesehen, welche eine Stange 19 aufweisen, deren eines Ende mit dem Bügel 1 fest verbunden und deren anderes Ende sich mit Reibung in einen Teil 20 erstreckt, der unter der Wirkung einer Druckfeder 21 steht. Die Druckfeder 21 wird dabei von einem Bolzen 22 gehalten. Das axiale Spiel, welches das Lösen des Bügels 1 durch eine Bewegung nach links mit Bezug auf die Halterung 4 und die Bremsscheibe 5 ermöglicht, muß die Hälfte des axialen Spiels betragen, welches mittels der Stange 17 und deren Anschläge 16 und 18 das Bestreben hat, den Bügel 1 mit Bezug auf die Bremsscheibe 5 nach rechts zu verlagern. Auf diese Weise wird eine gleiche Verteilung des Lüftspiels, auf beiden Seiten der Bremsscheibe 5 erreicht, wobei das Spiel zudem unabhängig von der Abnutzung der Reibbeläge konstant bleibt.Advantageously, 3 adjusting devices are provided in the interior of the guide axles, which have a rod 19, one end of which is fixedly connected to the bracket 1 and the other end of which is extends with friction into a part 20 which is under the action of a compression spring 21. The compression spring 21 is held by a bolt 22. The axial play, which the loosening of the bracket 1 by allows movement to the left with respect to the bracket 4 and the brake disc 5, the Half of the axial play, which by means of the rod 17 and its stops 16 and 18 the Has endeavored to move the bracket 1 with respect to the brake disc 5 to the right. In this way an equal distribution of the clearance is achieved on both sides of the brake disc 5, with the game also remains constant regardless of the wear and tear of the friction linings.

Weiterhin ermöglicht die erfindungsgemäße Anordnung ein leichtes Auswechseln der Bremsbeläge, wobei der Steg 12 unter Zusammendrückung der Rückholfeder 10 zurückgedrückt, der Sprengring 14 weggenommen und der Steg 12 herausgezogen wird. Die Stangen 13, die mit der Verankerung der Bremsbeläge 6' Bajonetteingriff haben, werden hierdurch frei, so daß auch sie herausgezogen werden können. Nach dem Abnehmen der Bremsbeläge 6' kann man den Bügel 1 nach links (s. Zeichnung) bewegen und die Zapfen 23, welche die Bremsbeläge 6 halten, lösen. Hierauf können leicht die neuen Bremsbeläge, beginnend mit den Bremsbelägen 6, eingesetzt werden, worauf nach dem axialen Verschieben des Bügels 1 nach rechts die Bremsbeläge.6' aufgeschoben werden können, welche mittels der Stangen 13 gehalten werden. Anschließend wird dann der Steg 12 wieder eingesetzt.Furthermore, the arrangement according to the invention enables easy replacement of the brake linings, with the web 12 pushed back under compression of the return spring 10, the snap ring 14 removed and the web 12 is pulled out. The rods 13 with the anchoring of the brake pads 6 'have bayonet engagement, are thereby free so that they can also be pulled out. After removing the brake pads 6 'one can move the bracket 1 to the left (see drawing) and the pins 23, which hold the brake pads 6, loosen. The new brake pads, starting with the brake pads 6, are used, whereupon after the axial displacement of the bracket 1 to the right, the brake linings 6 'can be pushed on, which are held by means of the rods 13 will. The web 12 is then inserted again.

Der Schutz der Gleitflächen ist durch Gummidichtungen 24 und 25 gewährleistet.The protection of the sliding surfaces is ensured by rubber seals 24 and 25.

Die Wirkungsweise der erfindungsgemäßen Teilbelagscheibenbremse ist wie folgt:The function of the partially lined disc brake according to the invention is as follows:

Beim Bremsen wird hydraulischer Druck über eineWhen braking, hydraulic pressure is applied via a

ίο nicht dargestellte Leitung in den Zuspannzylinder 7 eingeleitet, wodurch einerseits mittels des Kolbens 2 der Bremsbelag 6' und andererseits mittels des Bügels 1 und der Druckstücke 8 und 9 der Bremsbelag 6 gegen die Bremsscheibe 5 gedrückt wird. Die Rückholfeder 10 ist nun zwischen dem Steg 12, welcher der Vorschubbewegung des Bremsbelages 6' nach links gefolgt ist, und dem beweglichen Bügel 1, der sich nach rechts bewegt hat, zusammengedrückt.ίο line, not shown, into the clamping cylinder 7 initiated, whereby on the one hand by means of the piston 2 of the brake lining 6 'and on the other hand by means of the bracket 1 and the pressure pieces 8 and 9, the brake lining 6 is pressed against the brake disc 5. The return spring 10 is now between the web 12, which follows the feed movement of the brake lining 6 ' followed to the left, and compressed the movable bracket 1, which has moved to the right.

Wenn sich infolge Abnutzung die Schulter der Stange 17 gegen den Anschlag 18 abstützt und diesen bewegt, drückt dieser gegen das Reibstück 15. Demzufolge tritt das Reibstück entsprechend der Abnutzung in seine Ausnehmung ein, wodurch der Steg 12 dem Bügel 1 genähert wird.If, due to wear, the shoulder of the rod 17 is supported against the stop 18 and this moves, this presses against the friction piece 15. As a result, the friction piece occurs in accordance with the wear into its recess, whereby the web 12 is brought closer to the bracket 1.

Wenn der hydraulische Druck aufhört, führt die Rückholfeder 10 den normalen Abstand zwischen dem Bügel 1 und dem Steg 12 und damit zwischen den Bremsbelägen wieder herbei. Andererseits entspricht das Spiel, das zwischen dem Reibstück 15 und den Anschlägen 16 und 18 vorgesehen ist, dem zwischen der Bremsscheibe 5 und deren Bremsbelägen vorhandenen Spiel, so daß dieses unabhängig von der Abnutzung konstant ist und sich gleichmäßig auf beide Seiten der Bremsscheibe 5 verteilt. Die Begrenzung des Spiels wird außerdem durch die Stangen 19 unterstützt, welche bei der Rückbewegung' des Bügels 1 den Teil 20 entgegen der Wirkung der Feder mitnehmen und bei einer das Normale überschreitenden Rückbewegung mit Reibung im Inneren des Teils 20 gleiten.When the hydraulic pressure ceases, the return spring 10 leads the normal distance between the bracket 1 and the web 12 and thus between the brake linings again. On the other hand corresponds to the game that is provided between the friction piece 15 and the stops 16 and 18 between the brake disc 5 and its brake pads existing game, so that this is independent of the Wear is constant and is evenly distributed on both sides of the brake disc 5. The limitation the game is also supported by the rods 19, which when the bracket 1 moves back, the part 20 against the action of the spring and with a return movement exceeding the normal with friction inside the part 20 slide.
