zwiscbfcD dem äußeren Ringkolben (17) und der dem Federelement (22) abgewandten Seite des inneren Ringkolbens (18) ist eine druckbeaufschlagbare zweite Kammer (23) angeordnet, bei deren Druckbeaufschlagung der äußere und der innere Ringkolben (17 bzw. 18) entgegengesetzt der Kraft des Federelements (22) vorgespannt sind;A spring element (22) which acts on the outer ring piston (17) and the inner ring piston (18) in the brake actuation direction is arranged in the first chamber (22a);
Between the outer ring piston (17) and the side of the inner ring piston (18) facing away from the spring element (22) there is a pressurizable second chamber (23), when the pressure is applied, the outer and the inner ring piston (17 or 18) oppose the force the spring element (22) are biased;

die zweite Kammer (23) wird von einem die Bremsbewegung des inneren Ringkolbens (18) übertragenden Kolbenteil (18a;durchdrungen.the second chamber (23) is controlled by the braking movement of the inner ring piston (18) transmitting piston part (18a; penetrated.

bzw. Federspeicherkolben 18 angeordnet Zwischen dem vom Druckring 18a des Kolbens 18 durchdrungenen Boden des Kolbens 17 und dem Kolben 18 befindet sich eine Ringkammer 23. deren Anschluß 23a über eine Leitung 24 und über ein Druckbegrenzungsventil 25 mit dem Handbremsventil 26 in Verbindung steht
Die Funktion ist wie folgt:Between the bottom of the piston 17 penetrated by the pressure ring 18a of the piston 18 and the piston 18 there is an annular chamber 23, the connection 23a of which communicates with the handbrake valve 26 via a line 24 and a pressure relief valve 25
The function is as follows:

Beim Betätigen des Motorwagen-Bremsveiwiles 21 wird die Ringkammer 19 über die Leitung 20 und den Anschluß 19a belüftet Der sich darin aufbauende Druck bewegt auf der einen Seite den Ringkolben 17 zusammen mit Ringkolben 18 und dem mit dem Druckring 18a in Wirkverbindung stehenden Bremsring 10 und Bremsbelag 12 gegen die umlaufende Bremsscheibe 8 und auf der anderen Seite den Ringzylinder 16 mit Bremsring 9 und Bremsbelag 11 gegen die umlaufende Bremsscheibe 7.When actuating the motor vehicle brake lever 21 the annular chamber 19 is ventilated via the line 20 and the connection 19a The pressure building up therein moves on the one hand the annular piston 17 together with the annular piston 18 and that with the pressure ring 18a operatively connected brake ring 10 and brake lining 12 against the rotating brake disc 8 and on on the other side, the ring cylinder 16 with the brake ring 9 and brake lining 11 against the rotating brake disc 7th

Zur Betätigung der Feststellbremsanlage oder zur abstufbaren Betätigung der Hilfsbremsanlage wird das Handbremsventil 26 in die entsprechende Stellung gebracht. To operate the parking brake system or to operate the auxiliary brake system in stages, the Hand brake valve 26 brought into the appropriate position.

Dabei wird der während des normalen Fahrbetriebes und auch bei betätigter Betriebsbremse in Kammer 23 vorhandene, der Feder 22 entgegenwirkende Druck über Anschluß 23a entlüftet so daß die Spannung der Feder 22 auf der einen Seite den Ringkolben 18 mit Druckring 18a, Bremsring 10 und Belag 12 gegen die Bremsscheibe 8 bewegt und auf der anderen Seite bewegt sich der Ringkolben 18 gegen den Ringzylinder 16.The during normal driving operation and also when the service brake is activated in chamber 23 existing, the spring 22 counteracting pressure via port 23a vented so that the tension of the Spring 22 on the one hand the annular piston 18 with pressure ring 18a, brake ring 10 and lining 12 against the Brake disk 8 moves and on the other hand the annular piston 18 moves against the annular cylinder 16.

welcher die Bewegung weiter mit Bremsring 9 und Belag 11 gegen die Bremsscheibe 7 fortsetztwhich continues the movement with the brake ring 9 and lining 11 against the brake disc 7

Die Erfindung betrifft eine pneumatisch oder hydraulisch gesteuerte Scheibenbremse nach dem Oberbegriff des Patentanspruchs.The invention relates to a pneumatic or hydraulic controlled disc brake according to the preamble of the claim.

Eine derartige Scheibenbremse ist aus der DE-OS 24 41 605 bekannt Diese bietet eine gedrängte, wenig axialen Bauraum erfordernde Bauweise für eine Betätigung durch zwei Betriebsbremskreise.Such a disc brake is known from DE-OS 24 41 605. This offers a compact, little Axial space required construction for actuation by two service brake circuits.

Der Erfindung liegt die Aufgabe zugrunde, eine Scheibenbremse der eingangs genannten Art mit einfachen Mitteln so zu verbessern, daß sie als kombinierte Betriebsbrems/Federspeicher-Hilfs- und/oder -Feststellbremse einstellbar ist.The invention is based on the object of providing a disc brake of the type mentioned at the beginning with simple Means to improve so that they can be used as a combined service brake / spring-loaded auxiliary and / or parking brake is adjustable.

Die Erfindung ermöglicht damit die Übertragung der bekannten gedrängten Bauweise auf eine erfindungsgemäße kombinierte Scheibenbremse.The invention thus enables the known compact design to be transferred to one according to the invention combined disc brake.

Die Erfindung wird nachstehend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels erläutert.The invention is explained below with reference to an embodiment shown in the drawing.

Die Betätigung der Bremse besteht aus einem zwischen den Bremsringen 9 und 10 gelagerten ringförmigen Bremszylinder 16, einem in diesem axial beweglich gelagerten, durch Dichtringe abgedichteten Betriebsbrems-Ringkolben 17 und einem im Hohlraum des Ringkolbens 17 axial beweglich gelagerten Federspeicherbremskolben 18, welcher mit dem fest verbundenen, mit dem Bremsring 10 in Wirkverbindung stehenden Druckring 18a,den Betriebsbremskolben ^abgedichtet durchdringt. "The actuation of the brake consists of an annular ring mounted between the brake rings 9 and 10 Brake cylinder 16, a service brake ring piston which is axially movably mounted in this and is sealed by sealing rings 17 and a spring-loaded brake piston mounted axially movably in the cavity of the annular piston 17 18, which is connected to the firmly connected, with the brake ring 10 in operative connection Pressure ring 18a, the service brake piston ^ penetrates sealed. "
