Description

Bremsvorrichtung für Kraftfahrzeuge mit auf die Innenseite der Bremstrommel wirkender, bogenförmiger, mehrfach abgestützter Bremsbacke. Es sind bereits Bremsvorrichtungen für Kraftfahrzeuge bekannt, bei welchen bogenförmige, mehrfach abgestützte Bremsbacken auf die Innenseite der Bremstrommeln wirken und durch einen geringen Kraftaufwand eine starke Bremswirkung ermöglichen. Hierbei tritt der Übelstand auf, daß die Bremsbacke infolge Abnutzung ihre konzentrische Lage zur Bremstrommel verliert und durch eine zufällige Punktberührung mit der letzteren mitgenommen wird und eine plötzliche und unerwünschte starke Bremsung hervorruft.Braking device for motor vehicles with on the inside of the brake drum acting, arched, multiple supported brake shoe. There are already braking devices known for motor vehicles in which arc-shaped, multi-supported brake shoes act on the inside of the brake drums and with little effort enable a strong braking effect. Here the disadvantage occurs that the brake shoe loses its concentric position to the brake drum due to wear and a accidental point contact with the latter is taken and a sudden and causes undesirable heavy braking.

Um dies zu vermeiden, ist gemäß der Erfindung die Bremsvorrichtung dahingehend verbessert, daß die Bremsbacke im gelösten Zustande unter der Wirkung zweier innerer Zugfedern an zwei inneren Stützgliedern und einem äußeren Stützgliede anliegt, welche sämtlich von verstellbaren Exzentern gebildet werden, um eine konzentrische Einstellung der Bremsbacke zu ermöglichen.To avoid this, according to the invention is the braking device improved to the effect that the brake shoe in the released state under the effect two inner tension springs on two inner support members and one outer support member is applied, which are all formed by adjustable eccentrics to a concentric To enable adjustment of the brake shoe.

In der Zeichnung ist eine Vorderansicht der Bremstrommel mit der Bremsbacke dargestellt.In the drawing is a front view of the brake drum with the brake shoe shown.

Gegenüber der Innenwand der Bremstrommel a ist die Bremsbake angeordnet, welche aus einer starken Metallfeder b besteht, die mit einem Reibungsbelag e ausgestattet und an dem einen. Ende an einen Zapfen cl angelenkt ist. Das andere Ende der Backe b liegt frei auf einem Gliede e und träge einen Schuh/, auf welchen in der bekannten Weise der Bremsnocken g einwirken kann.The brake beacon is arranged opposite the inner wall of the brake drum a, which consists of a strong metal spring b, which is equipped with a friction lining e and on one. End is hinged to a pin cl. The other end of the cheek b lies free on a limb e and carries a shoe / on which in the known Way the brake cam g can act.

Die die Bremsbacke bildende Blattfeder b stützt sich andererseits auf Glieder h, i, welche, ebenso wie das Stützglied e, aus Exzentern bestehen, deren Winkelstellung durch geeignete Mittel regelbar ist. Schraubenfedern j, k dienen dazu, die Bremsbacke b in die normale Ruhestellung zurückzuführen, in welcher sie auf den drei Gliedern e, h, i ruht. Die vollkommen konzentrische Stellung der Backe kann also stets dadurch gesichert sein, daß die Stellung der Exzenter e, h, i entsprechend geregelt wird, so daß der Abstand der Außenseite der Bremsbacke von der Innenwand der Bremstrommel nur genau so groß wie nötig ist.The leaf spring b forming the brake shoe is supported on the other hand on members h, i which, like the support member e, consist of eccentrics, the angular position of which can be regulated by suitable means. Helical springs j, k are used to return the brake shoe b to the normal rest position in which it rests on the three links e, h, i. The completely concentric position of the shoe can therefore always be ensured that the position of the eccentrics e, h, i is regulated accordingly, so that the distance between the outside of the brake shoe and the inner wall of the brake drum is only as large as necessary.
