Abstract

The full-circle disc brake is spring-operated and released hydraulically or by compressed air, being particularly for motor vehicles. It has a rotary brake housing, and discs sliding freely, but unable to rotate, on a stationary brake support. An actuator separate from the latter incorporates the brake actuating springs. There are two stepped rings (12, 13) fitting one over the other, the space between them (21) being filled with oil or compressed air to release the brake. The springs (16, 17) act against the stepped rings opposite them.

Description

Durch Federspeicher mit Druckluft- oder Drucköl- By spring accumulator with compressed air or pressure oil

entlastung direkt betätigte Vollbelagscheibenbremse, inshcsondere für Kraftfahrzeuge Es sind Vollbelagscheibenbremsen mit umlaufendem Bremsgehäuse bekaniit, bei denen in lJmfangsrichtiing fest, axial frei beweglich die die Bremsbeläge tragenden Bremssche iben auf einem stationären Bremsträger angcordnet sind und bei denen, getrennt von letzteren, eine Betätigungseinheit vorgesehen ist, deren Zuspannkraft durch Federn erzeugt wird. Zum Lösen der Bremse wird der Federdruck durch Druckluft oder Drucköl aufgehoben. Die vorliegende Erfindung betrifft die Weiterentwicklung dieser Betätigungslösung und hat sich zur Aufgabe gesetzt, ihren Aufbau zu vereinfachen, um eine schmälere Bauweise u erzielen und das Gewicht der Bremse zu reduzicren. Relief of directly actuated full-lined disc brake, in particular for motor vehicles They are fully lined disc brakes with a circumferential brake housing It is known that the brake linings are fixed in the circumferential direction and freely movable axially bearing brake disks are arranged on a stationary brake carrier and at which, separately from the latter, an actuating unit is provided whose application force is generated by springs. To release the brake, the spring pressure is applied by compressed air or pressurized oil canceled. The present invention relates to further development this actuation solution and has set itself the task of simplifying its structure, to achieve a narrower design and to reduce the weight of the brake.

Erfindungsgemäss besteht die Betätigungseinheit der Bremse aus zwei sich umfassenden Stufenringen, deren Stufen-Ringraum zum Lösen der Bremse mit Druckluft oder -öl gcfiillt wird. An den Stufenringen liegen Federn an, welche ihre Federspannung auf den jeweils gegenüberliegenden Stufenring übertragen. I)er wesentliche Vorteil dieser (Lösung) Lösung besteht darin, dass die Summe der Federkräfte jeder Seite zur Wirkung gelangt.According to the invention, the brake actuation unit consists of two encompassing step rings, their step annulus to release the brake with compressed air or oil is filled. There are springs on the step rings, which keep their spring tension transferred to the opposite step ring. I) he essential advantage this (solution) Solution is that the sum of the spring forces each side has an effect.

In <Ieii Abbildungen sind Ausführungsbeispiele der Erfindung dargestellt. In lig. 1 ist als Beispiel eine Bremse an der llinterachse eines doppelt bereiften Lastkraftwagens gewählt. In Fig.Exemplary embodiments of the invention are shown in FIGS. In lig. 1 is an example of a brake on the rear axle of a double tire Selected truck. In Fig.

2 ist in einem Teillängsschnitt eine lösung dargestellt, bei der Hydrauliköl als Betriebsmittel verwendet wird und bei der das Bremsgehäuse innen statt aussen geschlossen ist.2 a solution is shown in a partial longitudinal section in which hydraulic oil is used as equipment and in which the brake housing is inside instead of outside closed is.

In Beispiel Fig. 1 trägt der mit 1 gekennzeichnete Acloskörper die Nahe 2, an der durch Schrauben 3 die Räder 4 und das radscitigc Bremsgehäuseteil 5 befestigt sind. Ucher geteilte Spannringe 6 ist mit dem radseitigen Bremsgehäuseteil 5 der Bremsdeckel 7 kraftschlüssig verbunden. Im von den Gehatiseteilen 5 und 7 gebildeten ringzylinderförmigen ilohlraum sind die beiden geteilten, mit Bremsbelag ausgerüsteten Bremsscloeibeio 8 und 9 angeordnet, die in Umfangsrichtung fest, axial jedoch frei heweglich auf dem Bremsträger 10, der mit der Ac lose 1 durch Schrauben 11 verbunden ist, sitzen.In example Fig. 1, the Aclos body marked 1 carries the Near 2, on which by screws 3 the wheels 4 and the radscitigc brake housing part 5 are attached. Ucher split clamping rings 6 is with the wheel-side brake housing part 5 of the brake cover 7 positively connected. In the case of parts 5 and 7 The ring-cylinder-shaped hollow space formed is the two divided, with brake lining equipped Bremsscloeibeio 8 and 9 arranged, the fixed in the circumferential direction, axially but freely movable on the brake carrier 10, which is loose with the Ac 1 by screws 11 is connected, sit.

Zwischen den Bremsscheiben ist die Betätigungseinheit gelagert, welche aus den zwei im Querschnitt 1,-förmigen Stufenringen 12 und 13 besteht, deren scheibenförmige Schenkel 121 und 131 durch Ringdichtungen 14 und 15 abgedichtet sind. Auf den Aussenseiten dieser Schenkel der beiden Stufenringe 12 tind 13 sind die Tellerfedern 1() tind 17 angeordnet, welche sich auf der Gegenseite auf den Druckringen 18 und 19 abstiitzen. Dcr Druckring 18 ist auf dem Stufenring 13 in axialer Richtung über eine Schulter 13 und einen Sprcngring 133 und der Druckring 19 auf dem Stufenring 12 über eine Schulter 122 und einen Sprengring 123 axial fest verbunden. Wird über den Stutzen 20 in den Stufenringraum 21 Druckluft geführt, so werden die beiden Tellerfedern 16 und 17 gespannt und der axiale, sich auf den Bremsscheiben 8 und 9 ausw irkende Anspressdruck aufgehoben. Die Bremse wird dadttrch gelöst.The actuation unit is mounted between the brake disks, which consists of the two in cross-section 1, -shaped step rings 12 and 13, the disk-shaped Legs 121 and 131 are sealed by ring seals 14 and 15. On the outside this leg of the two step rings 12 and 13 are the disc springs 1() tind 17, which are located on the opposite side on the pressure rings 18 and 19 brace. Dcr pressure ring 18 is on the step ring 13 in the axial direction a shoulder 13 and a snap ring 133 and the pressure ring 19 on the step ring 12 firmly connected axially via a shoulder 122 and a snap ring 123. Will over the nozzle 20 led into the step ring chamber 21 compressed air, so the two Belleville washers 16 and 17 tensioned and the axial, on the brake disks 8 and 9 e ecting contact pressure canceled. The brake is released dadttrch.

Bei der in Fig. 2 dargestellten Lösung ist das aus zwei Teilen 21 und 22 bestehende, innen geschlossene Bremsgehäuse aussen offen. Die beiden die Bremsbeläge tragenden Bremsscheiben 23 und 24 sind an nicht mitgezeichneten Bremsträgerarmcn, die das Bremsgehäuse aussen umfassen, aufgehängt. Zwischen den Bremsscheiben 23 und 24 ist die Betätigungseinheit angeordnet, die aus den zwei Stufenringen 25 und 26 zusammengesetzt ist, wobei der hydraulisch beaufschlagte Stufenringraum 27 durch die Dichtringc 251 und 261 abgedichtet ist. Die beiden äusseren Tellerfedern 28 stützen sich am äusseren Stufenring 25 und an einem Sprengring 262 des inneren Stufenrings 26 ab. Die inneren Tellerfedern 29 liegen am inneren Stiifenring 26 tind m Sprengring 252 des äusseren Stufenrings 25 an. Durch Zuführung von Drucköl über die Leitung 30 in den Stufenringraum 27 werden die L e e r s e i t eIn the case of the solution shown in FIG. 2, this consists of two parts 21 and 22 existing, internally closed brake housings open on the outside. The two the Brake disks 23 and 24 carrying brake linings are attached to brake carrier arms (not shown), which include the brake housing on the outside, suspended. Between the brake discs 23 and 24, the actuating unit is arranged, which consists of the two step rings 25 and 26 is composed, the hydraulically acted upon step annulus 27 through the sealing ring 251 and 261 is sealed. The two outer disc springs 28 are supported on the outer step ring 25 and on a snap ring 262 of the inner step ring 26 from. The inner disc springs 29 lie on the inner pin ring 26 and the snap ring 252 of the outer step ring 25. By supplying pressure oil via the line 30 in the step annulus 27 are the L e r s e i t e
