Die Erfindung betrifft eine Radbremse für Kraftfahrzeuge nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a wheel brake for motor vehicles according to the preamble of claim 1.

Elektrisch betätigbare Feststellbremsen und hydraulisch be­ tätigbare Betriebsbremsen sind in der Automobiltechnik hin­ reichend bekannt.Electrically actuated parking brakes and hydraulic be Service brakes can be used in automotive technology well known.

Aus der WO 92/068 76 ist eine Scheibenbremse bekannt, die hydraulisch betätigt als Betriebsbremse und Feststellbremse wirkt, wobei die Bremsbacken im Feststellmodus elektrisch arretiert werden. Hierzu werden die Bremsbacken zuerst hy­ draulisch an die Scheibe gepreßt und mittels einer Rändel­ mutter, die über einen Elektromotor zugefahren wird, auf ihrer Position gesichert.A disk brake is known from WO 92/068 76, which hydraulically operated as service brake and parking brake acts, the brake shoes electrically in the parking mode be locked. To do this, the brake shoes are first hy pressed drastically against the pane and using a knurl mother who is closed by an electric motor secured their position.

In der EP 0 729 871 A1 wird eine elektrisch betätigbare Feststellbremse vorgestellt, die als Schwimmsattelbremse aufgebaut ist und bei der der Bremssattel einen Bremsbelag in seiner Faust fest aufnimmt und der zweite Bremsbelag zur Betätigung der Feststellbremse mittels einer elektromotor­ betriebenen Spindel-Getriebeeinheit auf die Bremsscheibe gedrückt wird.EP 0 729 871 A1 describes an electrically operable Parking brake presented as a floating caliper brake is built and in which the brake caliper has a brake pad in his fist and the second brake pad Actuation of the parking brake by means of an electric motor operated spindle gear unit on the brake disc is pressed.

Beide aufgezeigten Bremsenvarianten sind entweder nur hy­ draulisch oder nur elektrisch betätigbar.Both brake variants shown are either only hy can be operated drastically or only electrically.

Der Erfindung liegt die Aufgabe zugrunde, eine hydraulisch betätigbare Betriebsbremse und eine elektromotorisch betä­ tigbare Feststellbremse mit möglichst wenigen einfach aufge­ bauten Teilen in einer Radbremse zu vereinigen.The invention has for its object a hydraulic Operable service brake and an electric motor operated Adjustable parking brake with as few as possible simply applied to combine built parts in a wheel brake.

Diese Aufgabe ist erfindungsgemäß durch eine Radbremse mit im Bremssattel gemeinsam integrierter elektrisch betätigba­ rer Feststellbremse und hydraulisch betätigbarer Betriebs­ bremse gemäß den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a wheel brake Electrically actuated jointly integrated in the brake caliper Parking brake and hydraulically operated operation Brake solved according to the features of claim 1.

Betriebsbremseneinheit und Feststellbremseneinheit sind hierzu gemeinsam in einem Gehäuse eines Bremssattels ange­ ordnet. Die Baugruppe der Feststellbremseinheit ist im am Achsschenkel befestigten Sattelschenkel integriert. Die Be­ triebsbremseneinheit wird im gegenüberliegenden Sattelschen­ kel so eingebaut, daß die Bremsbeläge beider Einheiten eine gemeinsame Wirklinie bilden, in deren Richtung die beiden Bremseneinheiten auf die zwischen den Bremsbelägen angeord­ nete Bremsscheibe einwirken.Service brake unit and parking brake unit are for this purpose together in a housing of a brake caliper arranges. The assembly of the parking brake unit is on Stub axle attached to the knuckle. The Be the drive brake unit is in the opposite saddle kel installed so that the brake pads of both units one form a common line of action, in the direction of which the two Brake units arranged on between the brake pads Act on the brake disc.

Die Bremsscheibe ist so aufgebaut, daß ein axial verschieb­ licher Reibring auf der Nabe des Rades angeordnet ist. Die Drehmomentenübertragung wird durch eine Verzahnung zwischen Reibring und Nabe gewährleistet. Die axiale Position des Reibrings auf der Nabe wird durch die Feststellbremsenein­ heit so eingestellt, daß ein Belagverschleiß kompensiert wird und der Bremskolben der hydraulischen Betriebsbremse im Ruhezustand an einem im Sattelgehäuse definierten hinteren Anschlag fest anliegt.The brake disc is constructed so that it moves axially Licher friction ring is arranged on the hub of the wheel. The Torque transmission is through a toothing between Friction ring and hub guaranteed. The axial position of the Friction rings on the hub are activated by the parking brakes unit is set so that lining wear compensates is and the brake piston of the hydraulic service brake in Hibernation on a rear defined in the saddle housing Stop is tight.

Im Falle einer Betriebsbremsung steht der Bremsbelag der Feststellbremseinheit auf einer festen Position und die Be­ triebsbremse wird mittels des Hydraulikkolbens betätigt. Dabei wird der Bremsbelag der Betriebsbremse gegen den Reib­ ring der Bremsscheibe gedrückt, der sich dann wiederum am Bremsbelag der Feststellbremse anlegt und abstützt.In the event of service braking, the brake pad is on Parking brake unit in a fixed position and the Be the drive brake is actuated by means of the hydraulic piston. The brake lining of the service brake against friction  ring of the brake disc pressed, which in turn is on Applying and supporting the brake pad of the parking brake.

Im Fall einer Feststellbremsung liegt der Bremskolben der hydraulischen Betriebsbremse an seiner hinteren Endlage fest am Sattelgehäuse an, wodurch der Bremsbelag auf einer festen Position der Bremsscheibe gegenüber steht. Um die Feststell­ bremse zu aktivieren, wird nun mittels eines Elektromotors und einer Spindel-Getriebeeinheit der Bremsbelag der Fest­ stellbremse ebenfalls gegen den Reibring der Scheibenbremse gedrückt, wodurch sich der Reibring auf der gegenüberliegen­ den Seite an den feststehenden Bremsbelag der Betriebsbremse anlegt und abstützt.In the case of parking braking, the brake piston is hydraulic service brake at its rear end position on the caliper housing, which keeps the brake pad on a solid Position of the brake disc is opposite. To determine Activating the brake is now done by means of an electric motor and a spindle gear unit the brake pad the hard parking brake also against the friction ring of the disc brake pressed, whereby the friction ring on the opposite the side to the fixed brake lining of the service brake creates and supports.

Der detaillierte Aufbau der erfinderischen Radbremse und weitere Vorteile sind der Fig. 1 aus der Zeichnung zu ent­ nehmen.The detailed structure of the inventive wheel brake and other advantages can be found in FIG. 1 from the drawing.

Fig. 1 Schnittdarstellung der Radbremse. Fig. 1 sectional view of the wheel brake.

Fig. 1 zeigt einen Schnitt durch die erfindungsgemäße Rad­ bremse 1. Die Radbremse 1 ist aus einem Bremssattel 7 und einer Bremsscheibe 6 aufgebaut. Der Bremssattel 7 kann wahl­ weise als Fest- oder Schwimmsattel ausgeführt werden. Das Ausführungsbeispiel ist mit einem Festsattel ausgestattet. Die Feststellbremseinheit 2 ist im Bremssattelschenkel 18 angeordnet, welcher die Radbremse mit dem Achsschenkel (nicht dargestellt) eines Fahrzeugs verbindet. Die Fest­ stellbremseinheit ist hauptsächlich aus einer Spindel 11 aufgebaut, die mittels Elektromotor 14 über ein Überset­ zungsgetriebe 15 und einer im Getriebe 15 integrierten Spin­ delmutter 16 axial verfahrbar ist. Am bremsscheibenseitigen Ende ist die Spindel 11 mit einer Anlage 11a für einen Bremsbelag 17 ausgestattet. Die Betriebsbremseneinheit 3 ist im zweiten Schenkel 19 des Bremssattels 7 der Feststellbrem­ seneinheit 2 gegenüber angeordnet. Die Betriebsbremsenein­ heit 3 besteht aus einem im Bremssattelgehäuse 7a nicht ge­ zeigten angeordneten Hydraulikanschluß, einem Hydraulikka­ nal, der den Anschluß mit dem Hydraulikvolumen zur Kolbenbe­ tätigung verbindet und dem Hydraulikkolben 12 selbst. Auf der der Bremsscheibe 6 zugewandten Seite des Hydraulikkol­ bens 12 ist ebenfalls ein Bremsbelag 20 angelegt. Die Brems­ scheibe 6 ist zweiteilig aus einem Reibring 8 welcher auf der Nabe eines Rades 9 sitzt, zusammengefügt. Um das Drehmo­ ment zu übertragen, sind an der Radnabe 9 und dem Reibring 8 Zahnkränze 13 so angeordnet, daß die Zähne der Kränze inein­ andergreifen und dadurch Umfangskräfte übertragen. Der Reib­ ring 8 ist axial zur Radnabe 9 verschiebbar. Fig. 1 shows a section through the wheel brake 1 according to the invention . The wheel brake 1 is constructed from a brake caliper 7 and a brake disc 6 . The brake caliper 7 can optionally be designed as a fixed or floating caliper. The embodiment is equipped with a fixed saddle. The parking brake unit 2 is arranged in the brake caliper arm 18 , which connects the wheel brake to the steering knuckle (not shown) of a vehicle. The fixed parking brake unit is mainly composed of a spindle 11 which is axially movable by means of an electric motor 14 via a transmission 15 and a transmission del nut 16 integrated in the transmission 15 . At the end of the brake disc, the spindle 11 is equipped with a system 11 a for a brake pad 17 . The service brake unit 3 is arranged in the second leg 19 of the caliper 7 of the parking brake unit 2 opposite. The Betriebsbremsenein unit 3 consists of a arranged in the brake caliper housing 7 a not shown hydraulic connection, a Hydraulikka channel that connects the connection with the hydraulic volume for piston actuation and the hydraulic piston 12 itself. On the brake disc 6 facing side of the Hydraulikkol bens 12 is also a brake pad 20 is applied. The brake disc 6 is composed of two parts from a friction ring 8 which sits on the hub of a wheel 9 . In order to transmit the torque, 8 sprockets 13 are arranged on the wheel hub 9 and the friction ring 8 so that the teeth of the rims engage in one another and thereby transmit circumferential forces. The friction ring 8 is axially displaceable to the wheel hub 9 .

Durch den axial auf der Radnabe 9 verschiebbaren Reibring 8 ergeben sich zwei Hauptvorteile der erfinderischen Radbremse 1. Zum einen können über die Nachstellung der Spindel 11 der Feststellbremseinheit 2 der Bremsbelagverschleiß ausgegli­ chen werden und zum zweiten kann das Bremslüftspiel so ein­ gestellt werden, daß der Hydraulikkolben 12 der Betriebs­ bremseneinheit 3 immer an seinem hinteren Anschlag anliegt und dadurch bei einer Betriebsbremsung nur ein minimaler Zustellweg, der entsprechend eine minimale Volumenaufnahme erzeugt, notwendig ist.Due to the axially displaceable on the wheel hub 9 friction ring 8 there are two main advantages of the inventive wheel brake 1. On the one hand, by adjusting the spindle 11 of the parking brake unit 2, the brake pad wear can be compensated for and, secondly, the brake clearance can be adjusted so that the hydraulic piston 12 of the service brake unit 3 always rests against its rear stop and, as a result, only a minimal delivery path, which correspondingly generates a minimal volume consumption, is necessary during service braking.

Im Falle einer Betriebsbremsung wird der Hydraulikkolben 12 über die hydraulische Bremsanlage betätigt. Der am Kolben 12 anliegende Bremsbelag 20 legt sich am Reibring 8 an und drückt diesen gegen den Bremsbelag 17 der durch die Spindel 11 der Feststellbremseinheit 2 in der entsprechenden Posi­ tion festgestellt ist.In the event of service braking, the hydraulic piston 12 is actuated via the hydraulic brake system. The applied to the piston 12 brake pad 20 lies on the friction ring 8 and presses it against the brake pad 17 which is determined by the spindle 11 of the parking brake unit 2 in the corresponding position.

In einer Parksituation wird die Feststellbremseinheit 2 über den Elektromotor 14 elektrisch betätigt. Die Spindel 11 wird zugestellt und der am Spindelende 11a anliegende Bremsbelag 17 legt sich am Reibring 8 der Bremsscheibe 6 an und drückt diesen gegen den am Hydraulikkolben 12 anliegenden Brems­ belag 20. Der Hydraulikkolben 12 stützt sich in seiner hin­ teren Endlage am Gehäuse 7a des Bremssattelssattels 7 ab. Durch den selbsthemmend ausgelegten Spindeltrieb, ist die Arretierung der Bremse sichergestellt und ein Feststellen des geparkten Fahrzeuges gewährleistet.In a parking situation, the parking brake unit 2 is actuated electrically by the electric motor 14 . The spindle 11 is delivered and the end of the spindle 11 a adjacent brake lining 17 of the brake disc 6 rests against the friction ring 8 and presses this covering of the abutting on the hydraulic piston 12 brake 20. The hydraulic piston 12 is supported in its towards more advanced end position on the housing 7 a the caliper 7 from. The self-locking spindle drive ensures that the brake is locked and that the parked vehicle is locked.
