Description

Innenbackenbremse mit vorzugsweise hydraulischer Spreizvorrichtung für Kraftfahrzeuge Die Erfindung bezieht sich auf eine Innenbackenbremse mit vorzugsweise hydraulischer Spreizvorrichtung für Kraftfahrzeuge, durch deren besondere Ausbildung der Wirkungsgrad der bisher bekannten Bremsen weiter erhöht wird.Inner shoe brake with preferably hydraulic spreading device for motor vehicles The invention relates to an inner shoe brake with preferably Hydraulic spreading device for motor vehicles, due to their special training the efficiency of the previously known brakes is further increased.

Zur Verbesserung der Wirkung von Backenbremsen sind bereits verschiedene Vorschläge gemacht worden. So ist :es beispielsweise bekannt, den Primärbacken über einen Lenkerhebe1 am Bremsschild anzuordnen. Bekanntlich wird dadurch eine zusätzliche Anpreßwirkung erzielt, als durch die Trommelreibung der Backen mitgenommen wird und durch diese Längsbewegung der Backen vom Lenker eine radial nach außen gerichtete Komponente erhält. Lenkerbremsen mit starren Backen haben den Nachteil, daß infolge der starkeneinseitigen Anpressung durch, den Lenker .eine ungleichmäßige Belagabnutzung stattfindet, wodurch die Anpressung ungleichmäßig wird.There are already various ways of improving the effectiveness of shoe brakes Suggestions have been made. So is: it is known, for example, to use the primary jaw to arrange a handlebar 1 on the brake shield. As is well known, this creates an additional A pressing effect achieved than is taken along by the drum friction of the jaws and through this longitudinal movement of the jaws of the handlebar a radially outward one Component receives. Handlebar brakes with rigid jaws have the disadvantage that as a result the strong one-sided pressure caused by the handlebars. an uneven pad wear takes place, whereby the contact pressure becomes uneven.

Es ist ferner bekannt, Bremsbacken an ihrem Steg zu schwächen oder mit Einschnitten zu versehen, wodurch die Backen biegsam werden und -sich infolgedessen beim Bremsvorgang gleichmäßig an die Trommel anlegen können. -Gemäß der Erfindung wird eine weitergehende Verbesserung der Bremswirkung von Innenbackenbremsen durch eine Vereinigung der beiden an sich bekannten Merkmale erreicht. derart, d:aß die Primärbacke über einen Lenker, die Sekundärbacke unmittelbar an einem Bolzen des Bremsschildes abgestützt ist, und daß gleichzeitig beide Backen eine Schwächung des Bremsbackensteges aufweisen. Nur die Vereinigung dieser beiden an sich bekannten Merkmale bedingen den Erfolg des Erfindungsgegenstandes.It is also known to weaken or brake shoes at their web to provide incisions, making the jaws pliable and consequently flexible can apply evenly to the drum during braking. -According to the invention a further improvement in the braking effect of inner-shoe brakes is achieved a union of the two known characteristics is achieved. such, d: ate the Primary jaw over a link, the secondary jaw directly on a bolt of the Brake shield is supported, and that at the same time both jaws are weakened of the brake shoe web. Only the union of these two known per se Features determine the success of the subject of the invention.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Abbildung dargestellt. An einem Bolzen i des Bremsschildes z ist der Sekundärbacken 3 unmittelbar, Primärbarken q. über einen Lenkerhebel, 5 angeordnet. Die beiden Backen weisen bei 6 bzw. 7 eine Schwächung des Backensteges auf. Die Bakken 3 und q. werden von einem bekannten; hydraulischen R.adbremszylinder beaufschlagt.An embodiment of the subject invention is shown in the figure shown. The secondary jaw 3 is directly on a bolt i of the brake shield z, Primary barges q. Arranged via a handlebar lever 5. The two jaws show 6 and 7 show a weakening of the cheek piece. Bakken 3 and q. will be of one known; hydraulic rear wheel brake cylinder acted upon.
