Abstract
Description
Es ist eine verstärkungsfreie Vollbelagscheibenbremse mitIt is a reinforcement-free full-lined disc brake with
umlaufendem Bremsgehäuse und zwei die Bremsbeläge tragenden, auf einem stationären Bremsträger axial beweglich, in Umfangsrichtung fest angeordneten Bremsscheiben mit einer von den Bremsscheiben getrennten Spreizeinheit bekannt, bei der die Spreizeinheit aus zwei Betätigungsringen besteht, die über Schrägbahnen und Betätigungsrollglieder miteinander in Verbindung stehen, von denen nur ein Betätigungsring zum Spreizen verdreht wird und dieser Betätigungsring seine Anpresskraft über Stützrollglieder auf einen in Umfangsrichtung festgehaltenen Druckring, der an der Bremsscheibe der einen Seite anliegt, überträgt, während der zweite Betätigungsring axial frei beweglich, in Umfangsrichtungsrichtung fest auf dem Bremsträger angeordnet ist und seine Anpresskraft durch Anlage an der anderen Bremsscheibe auf letztere überträgt, wobei die Verschleissteile von der durch Federn zusammengehaltenen Spreizeinheit getrennt sind.circumferential brake housing and two bearing the brake pads on one stationary brake carrier axially movable, brake disks fixed in the circumferential direction known with a spreading unit separated from the brake discs, in which the spreading unit consists of two actuating rings, which have inclined tracks and actuating rolling elements are in connection with each other, of which only one actuating ring for spreading is rotated and this actuating ring its contact force via support roller members on a pressure ring held in the circumferential direction, which is attached to the brake disc of the rests on one side, transmits, while the second actuating ring is axially freely movable, is fixedly arranged in the circumferential direction on the brake carrier and its contact pressure by contacting the other brake disc transfers to the latter, with the wearing parts are separated from the spreading unit held together by springs.
Ferner ist eine Weiterentwicklung dieser Lösung bekannt, bei der die beiden Druckringe über ihre Schrägbahnen durch die Betätigungsrollglieder aufeinander zentriert sind und die Verbindung des in Umfangsrichtung verdrehbaren Druckringes mit dem Stützring, der die zweite Bremsscheibe andrückt, über als Zylinderrollen ausgebildete Stützrollglieder, deren Laufflächen als parallele Stirnflächen ausgebildet sind, erfolgt.Furthermore, a further development of this solution is known in which the two pressure rings on their inclined paths through the actuating roller members on each other are centered and the connection of the pressure ring rotatable in the circumferential direction with the support ring that presses the second brake disc on as cylindrical rollers trained support roller members, the running surfaces of which are designed as parallel end faces are done.
Vorliegende Erfindung hat sich zur Aufgabe gesetzt, die zuletzt genannte Lösung in Richtung auf einfachere Herstellung und grössere Betriebssicherheit hin weiterzuentwickeln.The present invention has set itself the task of the latter Solution in the direction of simpler manufacture and greater operational reliability to develop further.
Die erfinderische Lösung besteht darin, dass die Stützrollen auf zwei konzentrischen Kreisen angeordnet, durch einen mit radialen Fortsätzen ausgerüsteten Käfig umfasst und nach innen und aussen durch axial wirkende Dichtringe geführt und abgedichtet sind.The inventive solution is that the support rollers on two arranged concentric circles, equipped with a radial projections Includes cage and guided inwards and outwards by axially acting sealing rings and are sealed.
Durch diese einfach montierbare Stützrollenanordnung ist gewährleistet, dass der Wirkungsgrad der Bremse über die gesamte Lebensdauer gleich bleibt, Infolge Punktberührung der Betätigungskugeln beeinträchtigt erfahrungsgemäss eine Verschmutzung der Betätigungskugeln sowie der Schrägbahnen den Wirkungsgrad der Bremse nicht; dagegen würde eine Verschmutzung der Laufflächen der Stützrollen infolge ihrer Linienberührung mit ihren Laufflächen, somit ihrer geringeren Hertzschen Pressung den Betätigungswirkungsgrad der Bremse verschlechtern. Dies wird durch die erfindungsgemässe Ausbildung der Wälzabstützung verhindert.This easy-to-assemble support roller arrangement ensures that the efficiency of the brake remains the same over its entire service life, as a result Experience has shown that point contact of the actuating balls impairs contamination the actuating balls and the inclined tracks do not affect the efficiency of the brake; on the other hand, the running surfaces of the support rollers would become dirty as a result of their line contact with their running surfaces, thus their lower Hertzian pressure, the actuation efficiency the brake deteriorate. This is achieved by the inventive design of the Rolling support prevented.
In den Zeichnungen ist ein Ausführungsbeispiel der Erfindung dargestellt. Fig. 1 zeigt einen in Fig. 2 mit A-B gekennzeichneten Teillängsschnitt einer mechanisch zugespannten Nutzfahrzeugbremse und Fig. 2 den in Fig. 1 mit C-D gekennzeichneten Querschnitt durch Dichtringe und Abstützrollglieder. Im Beispiel handelt es sich um eine Bremse mit aussen offenem Bremsgehäuse.In the drawings, an embodiment of the invention is shown. Fig. 1 shows a partial longitudinal section, identified by A-B in Fig. 2, of a mechanical applied commercial vehicle brake and FIG. 2 that marked in FIG. 1 with C-D Cross section through sealing rings and support rollers. In the example it is a brake with an externally open brake housing.
Das aus zwei mit 1 und 2 gekennzeichneten Gehäusehälften bestehende, symmetrisch aufgebaute Bremsgehäuse umschliesst die an den stationären Bremsträgerarmen 3 aufgehängten, mit Bremsbelag ausgerüsteten Bremsscheiben 4 und 5. Zwischen letzteren ist die durch Federn 16 zusammengehaltene, aus den mit Schrägbahnen ausgerüsteten Druckringen 6 und 7 mit den dazwischenliegenden, durch einen Käfig 8 gehaltenen Spreizkugeln 9, den Stützrollen 10 mit ihrem gestanzten Käfig 11, den beiden axial wirkenden Dichtringen 12 und 13, sowie dem Stützring 14 bestehende Spreizeinheit angeordnet. Infolge der eben ausgebildeten Abstützfläche des Druckringes 7 kann bei Erwärmung der Bremse und unterschiedlicher Dehnung von Druckring 7 und Stützring 14 kein Verklemmen der Spreizeinheit eintreten. Der Raum, in dem sich der gestanzte Käfig 11 mit den Stützrollen 10 befindet, kann mit einer Heisslager-Fettfüllung versehen werden. Die Lippen der Dichtungen 12 und 13 verhindern einerseits das Austreten des Schmiermittels sowie das Eindringen von Schmutz und damit die Beeinträchtigung der Abrollbewegung der Stützrollen auf ihrer Abstützfläche.The two housing halves marked 1 and 2, symmetrically constructed brake housing encloses the stationary brake carrier arms 3 suspended brake disks 4 and 5 equipped with brake pads. Between the latter is held together by springs 16, from the with inclined tracks equipped pressure rings 6 and 7 with the intermediate, by a cage 8 held expansion balls 9, the support rollers 10 with their stamped cage 11, the two axially acting sealing rings 12 and 13, as well as the support ring 14 existing Spreading unit arranged. As a result of the flat support surface of the pressure ring 7 can with heating of the brake and different expansion of pressure ring 7 and Support ring 14 no jamming of the expansion unit occur. The room in which the punched cage 11 with the support rollers 10 can be filled with hot bearing grease be provided. The lips of the seals 12 and 13 on the one hand prevent leakage of the lubricant as well as the penetration of dirt and thus the impairment the rolling movement of the support rollers on their support surface.
