Description
Durch Luft- oder Flüssigkeitsdruck betätigte Scheibenbremse Es sind durch Luft oder Flüssigkeitsdruck betätigte Scheibenbremsen mit umlaufendem Bremsgehäuse und zwei in diesem auf einem feststehenden Bremsträger axial beweglich gelagerte Bremsscheiben bekannt. Die letzteren sind an der Außenseite mit Bremsbelag und an der Innenseite mit einander gegenüberliegenden Ausnehmungen versehen, die in Umfangsrichtung ansteigende Schrägflächen aufweisen und in denen Kugeln gelagert sind, über welche die beiden Bremsscheiben miteinander in Verbindung stehen. Jede Bremsscheibe ist in einer Drehrichtung frei beweglich. Werden die beiden Bremsscheiben gegeneinander in Umfangsrichtung verdreht, dann werden sie gegen das umlaufende Bremsgehäuse gepreßt. Die gegenseitige Verdrehung der Bremsscheiben erfolgt durch entgegengesetzt gerichtete, mit je einer Bremsscheibe mechanisch gekuppelte Kolben eines gemeinsamen Bremszylinders.Disc brakes operated by air or fluid pressure There are Disc brakes operated by air or fluid pressure with a rotating brake housing and two axially movably mounted in this on a stationary brake carrier Brake discs known. The latter are on the outside with brake lining and on the inside provided with opposing recesses in the circumferential direction have rising inclined surfaces and in which balls are mounted, over which the two brake discs are connected to each other. Every brake disc is Freely movable in one direction of rotation. Are the two brake discs against each other rotated in the circumferential direction, then they are pressed against the rotating brake housing. The mutual rotation of the brake discs takes place by oppositely directed, Mechanically coupled pistons of a common brake cylinder each with a brake disc.
Es sind auch schon Scheibenbremsen der vorbezeichneten Art vorgeschlagen worden, bei denen die Bremszylinder senkrecht oder im stumpfen Winkel zur Bremsenachse angeordnet sind.Disc brakes of the aforementioned type have also been proposed where the brake cylinder is perpendicular or at an obtuse angle to the brake axis are arranged.
Der Erfindung liegt die Aufgabe zugrunde, derartige Scheibenbremsen im Sinne einer günstigeren Raumausnutzung zu verbessern.The invention is based on the object of disc brakes of this type to improve in terms of a more favorable use of space.
Die Lösung dieser Aufgabe besteht erfindungsgemäß darin, daß Bohrungen des Bremsträgers in an sich bekannter Weise als-- Bremszylinder Verwendung finden, in denen in ebenfalls an sich bekannter Weise je zwei Kolben angeordnet sind, welche über Stößel mit Fortsätzen der Bremsscheiben in kraftschlüssiger Verbindung stehen. Die Kolben der Bremszylinder stützen sich in diesen zur Aufnahme des von den Bremsscheiben zu übertragenden Drehmoments an Sprengringen ab.The solution to this problem is, according to the invention, that bores of the brake carrier in a manner known per se as - brake cylinders are used, in which two pistons are arranged in a manner also known per se, which are in positive connection with extensions of the brake disks via tappets. The pistons of the brake cylinders are supported in these to accommodate the brake disks torque to be transmitted on snap rings.
Durch die Erfindung ergibt sich gegenüber den zwischen den Bremsscheiben aufgehängten Bremszylindern neben der Vereinfachung auch noch der Vorteil, daß am Innendurchmesser der Bremsscheiben Platz zum Unterbringen der Rückzugfedern geschaffen ist. Außerdem wird eine bessere Raumausnutzung erzielt. Bei Ausbildung des Bremsträgers als Bremszylinder kann der Durchmesser der Bremsen kleiner gewählt, und die Rückzugfedern können am inneren Durchmesser der Bremsscheiben angebracht werden.The invention results in relation to the between the brake disks suspended brake cylinders in addition to simplification also have the advantage that on Inner diameter of the brake discs created space to accommodate the return springs is. In addition, a better use of space is achieved. When training the brake carrier as the brake cylinder, the diameter of the brakes can be selected smaller, and the return springs can be attached to the inner diameter of the brake discs.
Finden vier Bremszylinder und acht Betätigungskolben Verwendung, dann ergibt sich gegenüber der konstruktiven Lösung mit zwei Bremszylindern und vier Betätigungskolben noch der Vorteil einer an mehreren Stellen am Umfang der Bremsscheiben angreifenden Betätigungskraft. Außerdem kann eine Bremse mit vier Bremszylindern noch kleiner als eine Bremse mit zwei Bremszylindern gebaut werden, oder aber es steht mehr Raum für die im Innern der Bremse laufende Radnabe zur Verfügung.If four brake cylinders and eight actuating pistons are used, then arises compared to the constructive solution with two brake cylinders and four Actuating piston still has the advantage of being in several places on the circumference of the brake discs attacking actuation force. In addition, a brake with four brake cylinders can be built even smaller than a brake with two brake cylinders, or else it there is more space available for the wheel hub running inside the brake.
In Fig. 1 und 2 ist ein Ausführungsbeispiel veranschaulicht.An exemplary embodiment is illustrated in FIGS. 1 and 2.
Fig.1 stellt einen Längsschnitt entlang der Linie I-I in Fig. 2 dar; in Fig. 2 ist ein Querschnitt durch die Bremse entlang der Linie II-II in Fig. 1 veranschaulicht.Fig. 1 shows a longitudinal section along the line I-I in Fig. 2; in FIG. 2 is a cross section through the brake along the line II-II in FIG. 1 illustrated.
In Fig. 1 und 2 ist mit dem Bezugszeichen 1 der vorzugsweise aus Grauguß hergestellte Bremsträger versehen. Dieser enthält vier Bohrungen 2, die als Bremszylinder Verwendung finden. In diesen Bohrungen sind paarweise die Betätigungskolben 3 angeordnet. Die letzteren drücken über Stößel 4 auf an den Bremsscheiben 5 und 6 angebrachte Fortsätze 7. Die Bremsscheiben 5 und 6 sind mit Bremsbelägen 5' und 6' versehen. In der Mitte der Bohrungen 2 ist jeweils ein Sprengring 8 angeordnet, der zur Aufnahme des Drehmoments dient.In Fig. 1 and 2, the reference numeral 1 is preferably made of gray cast iron Manufactured brake carrier provided. This contains four bores 2, which act as a brake cylinder Find use. The actuating pistons 3 are arranged in pairs in these bores. The latter press on the brake disks 5 and 6 via tappets 4 Projections 7. The brake disks 5 and 6 are provided with brake linings 5 'and 6'. In the middle of the bores 2 a snap ring 8 is arranged in each case, which is used for receiving the torque is used.
Die Kugeln, welche in Ausnehmungen der Bremsscheiben 5 und 6 gelagert sind, tragen das Bezugszeichen 9. Beide Bremsscheiben werden in ihrer neutralen Stellung innerhalb des rotierenden Bremsgehäuses 12 durch drei auf dem Umfang der Bremsscheiben gleichmäßig verteilte Rückzugfedern 10 gehalten, die an Federdeckeln 11 aufgehängt sind.The balls, which are mounted in recesses in the brake disks 5 and 6 are, have the reference number 9. Both brake disks are in their neutral Position within the rotating brake housing 12 by three on the circumference of the Brake disks evenly distributed retraction springs 10 held on spring covers 11 are hung.
