Abstract

The invention concerns fully-lined disk brakes (6, 7, 8, 9, 10, 11) for vehicles which have a brake housing (8, 9) as well as two brake disks (6, 7) carrying brake linings fixed on a stationary brake carrier (5) and able to move freely in an axial direction but fixed in the circumferential direction. A hydraulic brake actuation device serving to actuate the brakes is mounted on the brake carrier (5) between the disk brakes (6, 7) to be freely movable in an axial direction. It consists of an inner ring piston (10) equipped with a feed connection (20) as well as an outer ring piston (11) with a vent connection (15). The inner ring piston (10) is secured against turning by the direct positive interlocking of the feed connection (20) through the brake carrier (5). The outer ring piston (11) engages in a toothing (53) of the brake carrier (5) in the circumferential direction at least indirectly. In this way, an offset angle between the feed connection (20) and the vent connection (15) is avoided.

Description

Die Erfindung betrifft eine Vollbelagscheibenbremse mit folgenden bekannten Merkmalen:The invention relates to a full lining disc brake with the following known features:

  • a) umlaufendes, zwei- oder mehrteiliges, außen geschlossenes Bremsgehäuse,a) all-round, two-part or multi-part, closed on the outside Brake housing,
  • b) stationärer, außen verzahnter Bremsträger,b) stationary, externally toothed brake carrier,
  • c) zwei, die Reibbeläge tragende, auf dem Bremsträger axial verschiebbar gelagerte Bremsscheiben,c) two, bearing the friction linings, axially on the brake carrier slidably mounted brake discs,
  • d) zwischen den Bremsscheiben angeordnete, getrennt von den Bremsscheiben axial verschiebbare, hydraulische Zweiring-Zuspanneinrichtung.d) arranged between the brake discs, separated from the brake discs axially movable, hydraulic Two-ring application device.

Die Erfindung hat sich zur Aufgabe gesetzt, die Zuspanneinrichtung der Bremse derart auszubilden, daß sich die radialen Mittenebenen von Betätigungs- und Entlüftungsstutzen gegeneinander nicht verdrehen können.The invention has set itself the task of the application device the brake in such a way that the radial center planes of actuating and ventilation ports against each other can twist.

Diese für einen einwandfreien Betriebszustand der Bremse schädliche Verdrehung der beiden Betätigungsringe gegeneinander erfolgt dadurch, daß infolge des in Umfangsrichtung unvermeidlichen Verzahnungs-Lüftspiels zwischen Bremsscheiben und Bremsträger bei kurz aufeinanderfolgenden Bremsungen der äußere, in Umfangsrichtung frei gelagerte Betätigungsring durch Anlage an der Bremsscheibe pulsierend um mm-Bruchteile verdreht werden kann, woran ihn weder der äußere Dichtring durch Anlage am inneren Betätigungsring, noch die in Umfangsrichtung elastischen Gummischutzbälge hindern können. Diese Bruchteile addieren sich.This is detrimental to the perfect operating condition of the brake Rotation of the two actuation rings against each other takes place in that due to the inevitable in the circumferential direction Gearing clearance between brake discs and brake carrier in the case of short consecutive braking the outer, in Circumferential direction freely mounted actuating ring by contacting the Brake disc can be rotated pulsating by fractions of mm, to which neither the outer sealing ring attaches itself to the inner Actuating ring, still the elastic in the circumferential direction Can prevent rubber bellows. These fractions add up.

Die Erfindung hat sich zur Aufgabe gesetzt, die Zuspanneinrichtung der Bremse derart auszubilden, daß sich die radialen Mittenebenen von Betätigungs- und Entlüftungsstutzen nicht gegeneinander verdrehen können. The invention has set itself the task of the application device the brake in such a way that the radial center planes of actuating and venting nozzles not against each other can twist.  

Zur Lösung dieser Aufgabe werden erfindungsgemäß die in Umfangsrichtung durch an den, den Bremsdruck übertragenden Fortsätzen kraftschlüssig mit den Betätigungsringen verbundenen Schutzbleche an ihrem Innenumfang mit gestanzter Verzahnung versehen, welche in die Außenverzahnung des Bremsträgers eingreift.To achieve this object, the in Circumferential direction through to the one transmitting the brake pressure Extensions non-positively connected to the actuation rings Fenders on their inner circumference with punched teeth provided which engages in the external teeth of the brake carrier.

In den Abbildungen ist mit 1 das Rad, welches zusammen mit dem Bremsgehäuseflanschteil 8 durch Radbolzen 2 an der Nabe 3 befestigt ist, gekennzeichnet. An den stationären Achsschenkel des Fahrzeugs ist der aus Blech gepreßte Bremsträger 5 mit Schrauben 4 befestigt. Auf seiner gerollten Verzahnung 5₃ trägt der Bremsträger axial frei beweglich die aus je zwei 180°-Segmenten bestehende, die Reibbeläge tragenden Bremsscheiben 6 und 7. Die Bremsscheiben sind von dem umlaufenden, außen radial verrippten, aus Bremsgehäuseflansch 8 und Deckelteil 9 bestehenden Bremsgehäuse umfaßt. Zwischen den Bremsscheiben ist die aus zwei konzentrischen, durch Vierkantdichtringe 12 und 13 abgedichteten Ringen 10 und 11 bestehende Zuspanneinrichtung ebenfalls axial frei beweglich gelagert. Die Bremsflüssigkeit zur Betätigung der Bremse wird der Zuspanneinrichtung durch den Bremsschlauch 22, welcher auf der nicht mit dargestellten Fahrzeugseite am Wagenkasten befestigt ist und mit dem am Innenring 10 der Zuspanneinrichtung durch Schrauben 21 1 verbundenen Stutzen 20 zugeführt. Zur Betätigung der Bremse wird die Bremsflüssigkeit in den Z-förmigen Betätigungsraum 14 geleitet. Der Stutzen 20 durchdringt den Bremsträger 5 durch dessen axiale Ausnehmung 5₅ und hält dadurch die Zuspanneinrichtung in Umfangsrichtung fest.In the figures, 1 denotes the wheel, which is fastened together with the brake housing flange part 8 to the hub 3 by wheel bolts 2 . The brake beam 5 pressed from sheet metal is fastened to the stationary steering knuckle of the vehicle with screws 4 . On its rolled toothing 5 ₃, the brake carrier carries axially freely movable, each consisting of two 180 ° segments, the brake pads bearing brake discs 6 and 7th The brake discs are encompassed by the circumferential, externally radially ribbed brake housing consisting of brake housing flange 8 and cover part 9 . Between the brake discs, the application device consisting of two concentric rings 10 and 11 , sealed by square sealing rings 12 and 13 , is also axially freely movable. The brake fluid for actuating the brake is supplied to the application device through the brake hose 22 , which is fastened to the vehicle body on the side of the vehicle (not shown) and with the connector 20 connected to the inner ring 10 of the application device by screws 21 1 . To actuate the brake, the brake fluid is conducted into the Z-shaped actuation chamber 14 . The connector 20 penetrates the brake carrier 5 through its axial recess 5 ₅ and thereby holds the application device in the circumferential direction.

Die Entlüftung des Betätigungsringraumes 14 erfolgt durch den Entlüftungsstutzen 15, dessen Sechskantkopf über einen Steckschlüssel durch die Öffnungen 8₁ und 9₁ des Bremsgehäuses 8, 9 hindurch verdreht werden kann.
