Description
Es ist allgemein bekannt, dass bei der Inbetriebnahme von Fahrzeugen die Arbeitsflächen der Bremsbacken sowie die Bremsbacken selbst auf Grund der Reibung dem Verschleiß unterliegen. Dieser Verschleiß führt zur Vergrößerung des Hubes des Bremspedals, was die Fahrsicherheit reduziert, da der Bremsweg verlängert wird.It is well known that when commissioning vehicles the work surfaces the brake shoes and the brake shoes themselves due to friction subject to wear. This wear leads to Magnification of the Hubs of the brake pedal, which reduces driving safety, since the Extended braking distance becomes.
Bekannt sind Vorrichtungen, die den Verschleiß der Bremsbacken und anderer der Reibung ausgesetzter Bestandteile der Bremsbaugruppe mithilfe eines Hebel-Sperrmechanismus mit einem Schreibtrieb kompensieren (siehe z.B. „Fachkunde Kraftfachfahrzeugtechnik", 25. Auflage, Verlag Europa-Lehrmittel, S. 451, Bild 3). Beim Bremsen wird auf Grund der Reibung eine große Wärmemenge freigesetzt. Dies führt zu einer Vergrößerung des Spiels und der entsprechenden Annäherung der Bremsbacken an die Bremstrommel.Known are devices that reduce the wear of brake shoes and others the friction of exposed components of the brake assembly using compensate for a lever lock mechanism with a write drive (See, e.g., "Fachkunde Kraftfachfahrzeugtechnik", 25th Edition, Verlag Europa-Lehrmittel, p. 451, picture 3). When braking is due to the friction a big one heat released. this leads to to an enlargement of the Game and the corresponding approach of the brake shoes to the Brake drum.
Allerdings kann sich dieses Spiel beim Anschließenden Abkühlen sehr verringern oder gar verschwinden, was zu einem ungewollten Anbremsen führen kann.Indeed This game can be very reduced or even reduced during the subsequent cooling down disappear, which can lead to an unwanted braking.

Regeleinrichtung
Deswegen wird in diesem Zustand die durch die Temperaturerhöhung bedingte Vergrößerung des Spiels nicht kompensiert, was den Hub des Bremspedals ansteigen lässt, beispielweise beim zweiten der zweien sofort aufeinander folgenden Bremsvorgängen.therefore is in this condition caused by the temperature increase Enlargement of the game not compensated, which increases the stroke of the brake pedal, for example in the second of the two immediately consecutive braking operations.
Außerdem kann es nach dem Abkühlen der Bremstrommel dazu kommen, dass das Spiel nach der Kompensierung durch die automatische Auseinanderbewegung der Bremsbacken sich verkleinert oder gar verschwindet.In addition, can it after cooling The brake drum come to the game after the compensation by the automatic movement apart of the brake shoes themselves reduced or even disappears.

Das Ziel der Erfindung ist die Schaffung einer Vorrichtung zur Aufrechterhaltung eines stabilen Spiels zwischen den Bremsbacken und der Bremstrommel bei beliebigen Temperaturschwankungen in der Bremsbaugruppe und ihrer Umgebung.The The aim of the invention is to provide a device for maintaining a stable game between the brake shoes and the brake drum at any temperature fluctuations in the brake assembly and their environment.
Das gestellte Ziel wird dadurch erreicht, dass die Nachstelleinrichtung eine Stange und einen Gewindestößel samt Mutter enthält, wobei die Mutter in der Wechselwirkung mit dem Führungszahn steht; die Einrichtung wird auch mit einer Leiste versehen, die sich neben der inneren, beispielsweise vorderen, Fläche der Bremstrommel befindet; die Leiste ist auf einem Ende der Stange befestigt und steht in der Wechselwirkung mit dem festen Anschlag; auf dem anderen Ende der Stange wird die Leiste mithilfe eines gefederten Hebels befestigt; der Hebel schlägt seinerseits mir einem Ende an den Ansatz der Stange an und mit dem anderen Ende- an die Mutter des Stößels; das Anschlagen des Hebels an die Mutter des Stößels erfolgt vorzugsweise durch eine Feder, z.B. eine Lamellenfeder.The Asked target is achieved by the adjustment a pole and a threaded plunger together Contains mother, wherein the nut is in interaction with the guide tooth; the device is also provided with a strip that adjoins the inner, for example, front, area the brake drum is located; the ledge is on one end of the pole attached and interacts with the fixed stop; On the other end of the pole is the ledge using a spring-loaded Fastened levers; the lever in turn beats with one end to the neck of the pole and with the other end- to the mother of the pestle; the Striking the lever to the mother of the plunger is preferably carried out by a spring, e.g. a lamellar spring.
Die Erfindung ist an Hand der dargestellten und beschriebenen Ausführungsbeispiele erläutert.The Invention is based on the illustrated and described embodiments explained.
