Description

Die Erfindung betrifft eine Teilbelag-Scheibenbremse mit zu beiden Seiten der Bremsscheibe axial verschiebbaren Bremsbacken, denen zum Verschieben je ein in einem Bremssattelgehäuse angeordneter Kolben zugeordnet ist und mit einem sich über das Bremssattelgehäuse erstreckenden Hebelgestänge, das die bei Verschiebung der Bremsbacken in Richtung auf die Bremsscheibe auftretenden Reaktionskräfte von der einen auf die andere Bremsbacke überträgt.The invention relates to a partially lined disc brake with axially displaceable brake shoes on both sides of the brake disc, each of which is used to move a piston arranged in a brake caliper housing is assigned and with a piston extending over the brake caliper housing extending lever linkage, which when the brake shoes are shifted in the direction of the Reaction forces occurring in the brake disc are transferred from one brake shoe to the other.

Bei den sogenannten Schwimmsattel-Teilbelag-Scheibenbremsen ist ein in einem Zylinder angeordneter Betätigungskolben vorgesehen, wobei die an Kolben und Zylinder angreifenden hydraulischen Kräfte auf die zu beiden Seiten der Bremsscheibe angeordneten Bremsbacken weitergeleitet werden. Die Übertragung der Kräfte von der im allgemeinen auf einer Seite der Bremsscheibe angeordneten Kolben-Zylinderanordnung auf die gegenüberliegende Bremsscheibenseite kann durch Gestänge erfolgen (DT-AS 1 131 950, GB-PS 708 748, FR-PS 1431417). Die bekannten Schwimmsattel-Teilbelag-Scheibenbremsen erfordern die bewegliche Aufhängung des Bremszylinders oder korrosionsempfindliche Gleitführungen für den Sattel, was zum Klemmen und damit zu einer Funktionsbeeinträchtigung der Bremse führen kann. Bekannt sind außerdem die sogenannten Festsattel-Teilbelag-Scheibenbremsen, bei denen das Sattelgehäuse, in dem die Betätigungszylinder mit den darin angeordneten Betätigungskolben auf jeder Seite der Bremsscheibe liegen, fest an einem Fahrzeugteil angebracht ist. Dies hat den Vorteil, daß die Bremsbacken unmittelbar an einem Teil des festen Bremssattels abgestützt sind, so daß eine Belastung der Führungen des Bremsanlegemechanismus durch die Umfangskräfte beim Bremsen entfällt.In the so-called floating-caliper, partially-lined disc brakes, one is arranged in a cylinder Actuating piston provided, the hydraulic forces acting on the piston and cylinder are passed on to the brake shoes arranged on both sides of the brake disc. The transfer of the forces from the piston-cylinder arrangement, which is generally arranged on one side of the brake disc on the opposite side of the brake disc can be done using a linkage (DT-AS 1 131 950, GB-PS 708 748, FR-PS 1431417). The known Floating-caliper, partially-lined disc brakes require the brake cylinder or the movable suspension Corrosion-sensitive sliding guides for the saddle, which leads to jamming and thus to a functional impairment the brake can lead. Also known are the so-called fixed-caliper, partially-lined disc brakes, in which the saddle housing, in which the actuating cylinder with the actuating piston arranged therein on each side of the brake disc, is firmly attached to a vehicle part. This has the Advantage that the brake shoes are supported directly on a part of the fixed brake caliper, so that a There is no load on the guides of the brake application mechanism due to the circumferential forces during braking.

Der Erfindung liegt die Aufgabe zugrunde, eine Scheibenbremse der eingangs genannten Gattung zu schaffen, bei der die-von Festsattelbremsen her bekannte vorteilhafte Abstützung der Bremsbacken anThe invention is based on the object of providing a disc brake of the type mentioned at the beginning create where the-known from fixed caliper brakes advantageous support of the brake shoes

ίο einem Teil des festen Bremssattels mit der vorteilhaften Anordnung des hydraulischen Systems auf einer Seite der Bremsscheibe gemäß einer Schwimmsattel-Teilbelag-Scheibenbremse kombiniert ist.ίο part of the fixed caliper with the advantageous Arrangement of the hydraulic system on one side of the brake disc in accordance with a floating-caliper, partially-lined disc brake is combined.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß die Kolben in einem gemeinsamen im Bremssattelgehäuse angeordneten Zylinder vorgesehen sind, wobei ein Kolben direkt mit der ihm zugeordneten Bremsbakke und der andere Kolben über das Hebelgestänge mit der diesem zugeordneten Bremsbacke in Wirkverbindung steht. Auf Grund dieser Ausbildung kann der Zylinder in dem der Radschüssel abgekehrten Bereich des Bremssattelgehäuses angeordnet sein, was einer thermisch günstigen Anordnung entspricht, wie sie für Schwimmsattel-Teilbelag-Scheibenbremsen typisch ist.To solve this problem, the invention provides that the pistons in a common in the caliper housing arranged cylinder are provided, with a piston directly with the brake jaw assigned to it and the other piston is in operative connection with the brake shoe assigned to it via the lever linkage stands. Due to this design, the cylinder in the area of the facing away from the wheel disc Be arranged brake caliper housing, which corresponds to a thermally favorable arrangement, as it is for Floating-caliper-partially-lined disc brakes are typical.

Die Übertragung der Betätigungskraft von der Betätigungsvorrichtung auf die der Betätigungsvorrichtung gegenüberliegende Seite der Bremsscheibe durch ein Hebelgestänge hat den Vorteil, daß keine korrosionsempfindlichen Gleitführungen für den Sattel oder den Rahmen erforderlich sind, wie das bei einer Schwimmsattel-Teilbelag-Scheibenbremse im allgemeinen der Fall ist. Andererseits werden aber die beim Bremsen auftretenden Umfangskräfte von den Bremsbacken unmittelbar auf das fest an einem Fahrzeugteil angebrachte Bremssattelgehäuse übertragen.The transmission of the operating force from the operating device to the side of the brake disc opposite the actuating device through a Lever linkage has the advantage that no corrosion-sensitive sliding guides for the saddle or the Frames are required, as is the case with a floating caliper partially lined disc brake is generally the case. On the other hand, they are when braking occurring circumferential forces from the brake shoes directly on the firmly attached to a vehicle part Transfer caliper housing.

Nach einer bevorzugten Ausführungsform wirkt der an der anderen Bremsbacke angreifende Teil des Hebelgestänges über eine geschlitzte Rückenplatte auf die betreffende Bremsbacke ein. Das Hebelgestänge besteht zweckmäßig aus zwei am Bremssattelgehäuse angelenkten, im wesentlichen parallelen Schwenkhebeln und einer diese gelenkig verbindenden Zugstange.According to a preferred embodiment, the part of the lever linkage which engages the other brake shoe acts on the brake shoe in question via a slotted back plate. The lever linkage consists expediently made up of two essentially parallel pivot levers articulated on the brake caliper housing and a tie rod connecting them in an articulated manner.

An dem Bremssattelgehäuse 1 sind zwei.Bremshebel 2 und 3 bei 25 drehbar gelagert. Mit ihren anderen Enden sind die beiden Hebel 2 und 3 gelenkig an einer sie verbindenden Zugstange 4 angebracht. According to the drawing, the partially lined disc brake a caliper housing 1 which is attached to a vehicle part. On the caliper housing 1 there are two brake levers 2 and 3 rotatably mounted at 25. With their other ends are the two levers 2 and 3 articulated to a tie rod 4 connecting them.

Das Bremssattelgehäuse 1 weist in der rechts von der Bremsscheibe 5 gelegenen Seite einen Betätigungszylinder 20 auf, in dem zwei Kolben 6 und 6a gleitbar angeordnet sind. Das Druckmittel wird durch den Druckmitteleinlaß 19 dem Betätigungszylinder 20 zugeleitet. Der eine Kolben 6a wirkt auf den Hebel 2, der andere Kolben 6 über die Handbetätigungseinrichtung 34 auf die Rückenplatte 11 und den damit verbundenen Bremsbelag 9. Zwischen den Kolben 6 und 6a ist in dem Zylinder 20 eine Nachstellvorrichtung 33 angeordnet.The brake caliper housing 1 has, on the right side of the brake disk 5, an actuating cylinder 20 in which two pistons 6 and 6a can slide are arranged. The pressure medium is fed to the actuating cylinder 20 through the pressure medium inlet 19. One piston 6a acts on the lever 2, the other piston 6 via the manual control device 34 on the back plate 11 and the associated Brake lining 9. An adjusting device 33 is arranged in the cylinder 20 between the pistons 6 and 6a.
