Description

Die Erfindung bezieht sich auf Innenbackenbremsen mit einer schwimmend zwischen zwei Bremsbackenenden angeordneten, vorzugsweise hydraulischen Spreizvorrichtung, insbesondere für Kraftfahrzeuge, und besteht darin, daß der Primärbacken in an sich bekannter Weise über einen Lenkerhebel und der Sekundärbacken in an sich ebenfalls bekannter Weise in Trommeldrehrichtung verschiebbar gelagert ist.The invention relates to internal shoe brakes with a floating between two brake shoe ends arranged, preferably hydraulic spreading device, in particular for motor vehicles, and consists in that the primary jaw in a manner known per se via a handlebar lever and the secondary jaws in a manner also known per se in the direction of rotation of the drum is slidably mounted.

Mit der Innenbackenbremse nach der Erfindung wird zunächst gegenüber den bekannten Innenbackenbremsen durch bessere Ausnutzung der Servowirkung eine bessere Bremswirkung erzielt. Weiter wird auch die Bremskraft besser, nämlich auf beide Bremsbacken nahezu gleichmäßig verteilt, so daß die Bremsbackenbeläge vollkommen aus- und gleichmäßiger abgenutzt werden, wodurch sowohl die Bremswirkung weiter verbessert als auch die Lebensdauer und Betriebssicherheit der Bremse erhöht werden.With the inner shoe brake according to the invention is first compared to the known Inner shoe brakes have a better braking effect through better utilization of the servo effect achieved. Next, the braking force is better, namely distributed almost evenly on both brake shoes, so that the Brake shoe linings are worn out completely and more evenly, which means that both the braking effect is further improved as well as the service life and operational safety the brake can be increased.

Die bekannten Innenbackenbremsen, bei denen beide Bremsbacken symmetrisch entweder über Lenker oder in Trommeldrehrichtung verschiebbar gelagert sind, weisen diese Vorteile deshalb nicht oder nicht in dem Maße auf, weil diese Vorteile sich je nach der Drehrichtung der Bremstrommel jeweils nur bei einem Bremsbacken einstellen, und zwar im ersteren Falle beim Primär- und im zweiten Falle beim Sekundärbacken.The well-known inner shoe brakes in which both brake shoes are symmetrical either are mounted displaceably via handlebars or in the direction of rotation of the drum, these advantages therefore do not have these advantages or not in the Measures because these advantages only vary depending on the direction of rotation of the brake drum set in one brake shoe, in the former case in the primary and in the second Trap in secondary baking.

Der Erfmdungsgegenstand vereinigt also in sich- die Vorteile beider bekannter Innenbak-The subject of the invention thus combines the advantages of both known interior bak-

kenbremsen. Wesentlich für die Erfindung war dabei die Erkenntnis, daß es im Fahrzeugbetrieb weniger! darauf ankommt, eine gleich gute Bremswirkung in beiden Fahrtrichtungen als vielmehr die größtmögliche. Bremswirkung bei Vorwärtsfahrt zu erzielen. Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Abbildung dargestellt. Zwei Bremsbacken ι und 2 werden in bekannter Weise hydraulisch durch Kolben in einem Bremszylinder 3 auseinandergespreizt und durch eine Rückzugfeder 4 in Ruhelage gehalten. Die Drehrichtung der Bremstrommel (in Vorwärtsfahrt) ist durch den Pfeilkenbremsen. Essential for the invention was the knowledge that it is in vehicle operation fewer! what matters is an equally good braking effect in both directions of travel rather than the greatest possible. To achieve braking effect when driving forward. An exemplary embodiment of the subject matter of the invention is shown in the figure. Two brake shoes ι and 2 are in a known manner hydraulically by pistons in a brake cylinder 3 spread apart and by a return spring 4 in the rest position held. The direction of rotation of the brake drum (in forward travel) is indicated by the arrow

iS gegeben. Danach ist 1 der Primärbacken und über einen Lenkerhebel 5 an einem Bolzen 6 gelagert, während der Sekundärbacken 2 unmittelbar an dem Bolzen 6 so gelagert ist, daß er sich in Drehrichtung der Bremstrommel gegen die Kraft einer zusätzlichen Rückzugfeder 7 vom Bolzen 6 abheben kann. Diese verschiebbare Lagerung wird beispielsweise dadurch erreicht, daß der Lagerbolzen in einem U-förmigen Ausschnitt 8 des Bremsbackenendes angeordnet ist.iS given. After that, 1 is the primary jaw and mounted on a bolt 6 via a handlebar lever 5, while the secondary jaw 2 is mounted directly on the bolt 6 so that it is in the direction of rotation of the brake drum can lift off the bolt 6 against the force of an additional return spring 7. These Slidable storage is achieved, for example, in that the bearing pin in a U-shaped cutout 8 of the brake shoe end is arranged.

Beim Betätigen der Bremse wird der Primärbacken in an sich bekannter Weise durch den Lenkerhebel 5 gleichmäßig an die Bremstrommel gedrückt und der Sekundärbacken ,durch die Bremstrommel mitgenommen, also •-vom Lagerbolzen abgehoben. Es wird dadurch auch ein sattes Anlegen und eine Rückwirkung des Sekundärbackens über die hydraulische Spreizvorrichtung auf den Primärbacken bewirkt, so daß vor allem mit geringerer Kraft eine höhere Bremswirkung, darüber hinaus jedoch noch andere Vorteile, wie bereits erwähnt, erzielt werden.When the brake is actuated, the primary jaw is activated in a manner known per se the handlebar lever 5 pressed evenly against the brake drum and the secondary jaws , taken along by the brake drum, ie • lifted off the bearing pin. It becomes through it also a full application and a reaction of the secondary jaw via the hydraulic Spreading device causes on the primary jaws, so that a higher braking effect, especially with less force, in addition, however, other advantages, as already mentioned, can be achieved.
