Abstract

The floating saddle disc brake, especially for vehicles with a brake support (1) taking the braking torque, has brake shoes (8,9) possessing a brake lining and a lining back-plate (6,7). A brake saddle (10) grips over the brake shoes (8,9) and the brake disc (3), and transmits the braking forces onto the braking shoes (8,9) indirectly operated by an integrated brake piston to which pressure is applied hydraulically. The brake support (1) has an arm (2) in each circumferential direction. Each arm (2) slopes, extends radially over the brake disc (3) and ends on the plane where axial extensions (4) are formed on the arms (2) extending on both sides of the brake disc (3). ADVANTAGE - Tensions are equalised near the brake lining so that equal deformation in the lining back plates and brake support are formed.

Description

Die Erfindung betrifft eine Schwimmsattel-Scheibenbremse, insbesondere für Kraftfahrzeuge, mit einem das Bremsmoment aufnehmenden Bremsträger mit beiderseits einer Bremsscheibe angeordneten, axial verschiebbaren Bremsbacken, die einen Bremsbelag und eine Belagrückenplatte aufweisen, und mit einem die Bremsbacken und die Bremsscheibe übergreifenden Bremssattel.The invention relates to a floating caliper disc brake, especially for motor vehicles, with a braking torque receiving brake carrier with a brake disc on both sides arranged, axially displaceable brake shoes, the one Have brake pad and a pad back plate, and with one overlapping the brake shoes and the brake disc Brake caliper.

Aus der DE-OS 28 45 275 ist eine gattungsgemäße Scheibenbremse bekannt, an deren Bremsträgerarme radial außen über der Bremsscheibe je ein Flansch angesetzt ist. Diese Flansche stützen je einen Führungsbolzen, der zur Führung des Bremssattels und der Bremsbacken dient. Die bekannte Lösung sieht vor, die Führungsbolzen an den Flanschen und am Bremsträger zu befestigen. Da die Führung des Bremssattels mit den Bolzenenden erfolgt, ist der Führungsbolzen stark belastet. Außerdem wirkt auf den Führungsbolzen ein durch die Umfangskräfte hervorgerufenes Biege- und Drehmoment, welches von der Führung, d.h. dem Flansch und dem Bremsträger, aufgenommen werden muß. Um alle diese Belastungen auffangen zu können, und um die Verformungen von Belagrückenplatte und Bremsträger auf der Kolbenseite, wie auch auf der Faustseite im Rahmen der Wechselfestigkeit auf ausreichende Standzeiten zu bringen, müssen der Führungsbolzen, die Flansche, die Belagrückenplatte und die Bremsträgerarme stabil und schwer ausgeführt sein.From DE-OS 28 45 275 is a generic Disc brake known, on the brake carrier arms radially outside A flange is attached above the brake disc. These Flanges each support a guide pin that is used to guide the Brake caliper and the brake shoe serves. The well-known solution provides for the guide bolts on the flanges and on the Fasten brake carrier. Because the leadership of the caliper with the bolt ends, the guide bolt is strong charged. It also acts on the guide pin through Circumferential forces caused bending and torque, which from the leadership, i.e. the flange and the brake carrier, must be included. To absorb all of these burdens to be able to, and to the deformations of backing plate and Brake carrier on the piston side as well as on the fist side sufficient fatigue life as part of the fatigue strength to bring the guide pin, the flanges, the Pad back plate and the brake carrier arms stable and heavy be executed.

Die Erfindung hat sich daher die Aufgabe gestellt, eine Schwimmsattel-Scheibenbremse zu schaffen, die eine Vergleichmäßigung der Spannungen, d.h. gleiche Verformungen in den Belagrückenplatten und dem Bremsträger im Bereich der Belaganlage bewirkt und auf die speziellen Probleme einer jeden Bremse abgestimmt werden kann, wie beispielsweise bei Reibkraftschwankungen zwischen kolbenseitigem und faustseitigem Belag.The invention has therefore set itself the task Floating caliper disc brake to create one Equalization of tensions, i.e. same deformations in the pad back plates and the brake carrier in the area of Pad system causes and on the special problems of a each brake can be tuned, such as at Fluctuations in friction force between the piston side and fist-sided covering.

Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Vom Bremsträger erstrecken sich in beide Umfangsrichtungen je ein Arm radial außen über die Bremsscheibe. Dort sind an die Arme sich in axialer Richtung erstreckende Fortsätze angeformt, die sich beiderseits der Bremsscheiben erstrecken. Durch diese Maßnahme können die Standzeiten der Belagrückenplatten und der Belagträger vergleichmäßigt und/oder erhöht werden.The task is characterized by the characteristics of the Claim 1 solved. From the brake carrier extend into both Circumferential directions one arm each radially on the outside Brake disc. There are arms in the axial direction extending projections formed on both sides of the Extend brake discs. Through this measure, the Service life of the backing plates and the backing be equalized and / or increased.

In vorteilhafter Weise weisen die axialen Fortsätze gemäß Anspruch 2 Führungsnute auf, die die Belagrückenplatten beider Bremsbacken in axialer Richtung führen. Dadurch, daß - bezogen auf das Kraftfahrzeug - die Abstützung der Umfangskräfte in je gleichem Maß innerhalb und außerhalb des Befestigungspunktes der axialen Fortsätze an den Bremsträgerarmen erfolgt, kompensieren sich die entstehenden Drehmomente wie bei einer Balkenwaage im Gleichgewicht. Daher werden auf die Bremsträgerarme und die Belagrückenplatte nur noch Kräfte übertragen, die sich in Form von Druck bzw. Zug gleichmäßig auf beide Arme verteilen können. So wird jeder einzelne optimal belastet und spannungsmäßig genutzt. Advantageously, the axial extensions have guide grooves that guide the lining back plates of both brake shoes in the axial direction. The fact that - based on the motor vehicle - the circumferential forces are supported to the same extent both inside and outside the attachment point of the axial extensions on the brake carrier arms, the resulting torques are compensated for as in a beam balance in equilibrium. For this reason, only forces are transmitted to the brake carrier arms and the pad back plate that can be evenly distributed in both arms in the form of pressure or tension. So each one is optimally loaded and used in terms of tension.

Die Erfindung läßt sich bei bolzengeführten Bremsbacken in gleicher Weise ausnutzen wie bei nutgeführten. Eine Weiterbildung der bolzengeführten Variante sieht gemäß Anspruch 4 vor, die axialen Fortsätze beiderseits der Bremsscheibe durch zu letzterer parallele Verbindungsteile zu verbinden. Diese Ausführung bewirkt eine erhöhte Stabilität, da die axialen Fortsätze und die Verbindungsteile einen geschlossenen Rahmen bilden. Dieser Rahmen sorgt dafür, daß die Kräfte gleichmäßig auf beide Bremsträgerarme verteilt werden und verhindert eine schräge Belastung.The invention can be in bolt-guided brake shoes exploit in the same way as with groove-guided. A Further development of the bolt-guided variant looks according to Claim 4 before, the axial extensions on both sides of the Brake disc by connecting parts parallel to the latter connect. This design results in increased stability, because the axial extensions and the connecting parts one form a closed frame. This framework ensures that the forces evenly distributed on both brake carrier arms and prevents an oblique load.

Gemäß Anspruch 5 weisen die Bremsträgerarme in vorteilhafter Weise in der Projektion auf die Mittelebene der Bremsscheibe eine bogenförmige, der Bremsscheibenachse zugewandte Kontur mit verschiedenen Krümmungsradien auf. Diese kontinuierlich oder abschnittsweise verschiedenen Radien beginnen an den Ansatzpunkten der axialen Fortsätze mit kleinen Radien und nehmen zum Bremsträger hin zu. Da bei Zunahme des durch die Umfangskräfte verursachten Biegemoments gleichzeitig die Kurvenwirkung abnimmt, ergibt sich innerhalb des Bremsträgerarms ein gleichmäßiger Spannungsverlauf.According to claim 5, the brake carrier arms advantageously Way in the projection on the central plane of the brake disc an arcuate contour facing the brake disc axis with different radii of curvature. This continuously or sectionally different radii start at the Starting points of the axial extensions with small radii and increase towards the brake carrier. Since with the increase of the Circumferential forces caused the bending moment at the same time Decreasing curve effect results within the Brake carrier arm an even voltage curve.

Mögliche Ausführungsformen der Erfindung werden anhand der Figuren erläutert.Possible embodiments of the invention are based on the Figures explained.

Fig. 1 zeigt eine Schwimmsattel-Scheibenbremse mit einem Bremsträger 1, dessen Arme 2 die Bremsscheibe 3 radial außen übergreifen und an denen axiale Fortsätze 4 angebracht sind. Diese axialen Fortsätze 4 weisen Führungsnute 5 auf, in denen die Belagrückenplatten 6, 7 der Bremsbacken 8, 9 in axialer Richtung beweglich geführt werden. Die Bremsbacken 8, 9 und die Bremsscheibe 3 werden vom Bremssattel 10 übergriffen, der die Kraft des in der Kolbenbohrung 11 gehalterten Bremskolbens 12 auf die äußere Bremsbacke 9 überträgt. Beide Bremsbacken 8, 9 weisen je einen auf der Belagrückenplatte 6, 7 angebrachten Bremsbelag 13, 14 auf. An den Fingern 15 des Bremssattels 10 ist eine Feder 16 eingehakt, die sich an den axialen Fortsätzen 4 abstützt und den Bremssattel gegen Ausheben sichert. Fig. 1 shows a floating caliper disc brake with a brake carrier 1 , the arms 2 overlap the brake disc 3 radially on the outside and on which axial extensions 4 are attached. These axial extensions 4 have guide grooves 5 , in which the pad back plates 6 , 7 of the brake shoes 8 , 9 are movably guided in the axial direction. The brake shoes 8 , 9 and the brake disc 3 are overlapped by the brake caliper 10 , which transmits the force of the brake piston 12 held in the piston bore 11 to the outer brake shoe 9 . Both brake shoes 8 , 9 each have a brake pad 13 , 14 attached to the pad back plate 6 , 7 . A spring 16 is hooked onto the fingers 15 of the brake caliper 10 , which is supported on the axial extensions 4 and secures the brake caliper against lifting out.

Fig. 2 zeigt die gleiche Anordnung wie Fig. 1. Man erkennt die radial außen über die Bremsscheibe 3 greifenden Arme 2 des Bremsträgers 1, an denen die axialen Fortsätze 4 angebracht sind. In den Führungsnuten 5 sind die Belagrückenplatten 6, 7 axial verschiebbar geführt. Sobald beide Bremsbacken 8, 9 in Eingriff mit der Bremsscheibe 3 stehen, wirken auf die Ansatzpunkte 17 die axialen Fortsätze 4 zwei entgegengesetzt gleich große Drehmomente durch die Umfangskräfte, die sich kompensieren. Durch geringe Verschiebung der Ansatzpunkte 17 in axialer Richtung läßt sich Kompensation für jeden Bremsentyp erreichen und somit an jede Fahrzeugserie anpassen. Der Pfeil 18 deutet die Drehrichtung der Bremsscheibe 3 an. Der einlaufseitige axiale Fortsatz 4 wird zugbelastet und der auslaufseitige druckbelastet durch die Umfangskräfte. FIG. 2 shows the same arrangement as FIG. 1. The arms 2 of the brake carrier 1 , which extend radially outside over the brake disc 3 and to which the axial extensions 4 are attached, can be seen. The pad back plates 6 , 7 are guided axially displaceably in the guide grooves 5 . As soon as both brake shoes 8 , 9 are in engagement with the brake disc 3 , the axial extensions 4 act on the attachment points 17, two oppositely equal torques by the circumferential forces, which compensate each other. By slightly shifting the attachment points 17 in the axial direction, compensation can be achieved for any type of brake and thus adapted to any vehicle series. The arrow 18 indicates the direction of rotation of the brake disc 3 . The inlet-side axial extension 4 is tensile and the outlet-side pressure is loaded by the circumferential forces.

Fig. 3 zeigt in Draufsicht ein zweites Ausführungsbeispiel. Alle Teile, die die gleiche Funktion wie in den Fig. 1 und 2 haben, sind mit um 20 erhöhten Zahlen bezeichnet. In diesem Fall bildet der Bremssattel 30 einen Rahmen um die Bremsbacken 28, 29 mit den Belagrückenplatten 26, 27 und den Bremsbelägen 33, 34. Die Arme 22 des Bremsträgers 21 übergreifen die Bremsscheibe 23, und die axialen Fortsätze 24 sind parallel zur Bremsscheibe 23 durch Verbindungsteile 40 miteinander verbunden. In Bohrungen 41, 42 sind Bolzen 43 zur axialen Führung der Belagrückenplatten 26, 27 gehaltert. Die Bolzen 43 sind durch eine Feder 44 vorgespannt, um Klappergeräusche zu vermeiden. In Umfangsrichtung stützen sich die Bremsbacken 28, 29 an Stützflächen 45, 46 der axialen Fortsätze 24 ab. Der Bremssattel 30 besteht aus zwei Teilen, die mit Schrauben 47 zusammengehalten sind. Er wird durch Führungsbolzen 48 am Bremsträger 21 axial beweglich gehaltert. Fig. 3 shows a second embodiment in plan view. All parts which have the same function as in FIGS. 1 and 2 are identified by numbers increased by 20. In this case, the brake caliper 30 forms a frame around the brake shoes 28 , 29 with the pad back plates 26 , 27 and the brake pads 33 , 34 . The arms 22 of the brake carrier 21 overlap the brake disk 23 , and the axial extensions 24 are connected to one another parallel to the brake disk 23 by connecting parts 40 . Bolts 43 for axially guiding the backing plates 26 , 27 are held in bores 41 , 42 . The bolts 43 are prestressed by a spring 44 in order to avoid rattling noises. In the circumferential direction, the brake shoes 28 , 29 are supported on support surfaces 45 , 46 of the axial extensions 24 . The brake caliper 30 consists of two parts which are held together by screws 47 . It is held axially movably by guide bolts 48 on the brake carrier 21 .

Fig. 4 zeigt im Schnitt entlang der Bremsscheibenebene von Fig. 3 den Bremsträger 21 mit seinen Armen 22, den axialen Fortsätzen 24 und den Verbindungsteilen 40. Dabei erkennt man die Bohrungen 42 für die Bolzen 43, die Bohrungen 49 zur Aufnahme der Führungsbolzen 48 und die Befestigungsbohrungen 50 mit den Schrauben 51, die den Bremsträger 21 am Achsschenkel (nicht dargestellt) halten. In dieser Darstellung sieht man außerdem die bogenförmigen Innenkonturen 52 der Arme 22, deren Radien 53, 54, 55 von den axialen Fortsätzen 24 her zum Bremsträger 21 hin zunehmen. Durch diesen Verlauf der Krümmung ergibt sich innerhalb der Arme ein gleichmäßiger Spannungsverlauf. FIG. 4 shows the brake carrier 21 with its arms 22 , the axial extensions 24 and the connecting parts 40 in section along the brake disc plane of FIG. 3. Here one can see the bores 42 for the bolts 43 , the bores 49 for receiving the guide bolts 48 and the fastening bores 50 with the screws 51 which hold the brake carrier 21 on the steering knuckle (not shown). This illustration also shows the arcuate inner contours 52 of the arms 22 , the radii 53 , 54 , 55 of which increase from the axial extensions 24 towards the brake carrier 21 . This course of the curvature results in a uniform course of tension within the arms.
