Description

Bremskraftausgleichvorrichtung für Bremsen von Kraftfahrzeugen Bei Fahrzeugbremsen hat man schon vorgeschlagen, im Zusatz zu den Hauptbremsbacken, die bei Anstellung der Bremsen gegen den zu bremsenden Teil gedrängt werden, eine Hilfsbremsbacke anzuordnen, die die Bremswirkung erhöht, und diese Hilfsbremsbacke schwingbar unter Vermittlung eines Hebels mit einer Hauptbremsbacke zu verbinden. Die vorliegende Erfindung bezieht sich auf eine Bremseinrichtung mit einer solchen Hilfsbacke. Die Hilfsbacke wird jedoch nicht durch einfache Hebelübersetzung von der einen Hauptbremsbacke gegen den Flansch angedrückt, sondern es ist zwischen Hebel und Hilfsbremsbacke ein mit Flüssigkeit gefüllter Zylinder angeordnet, der den Hebeldruck auf die Hilfsbremsbacke weiterleitet. Wird diese Bremsanstellung dazu benutzt, um gleichzeitg mehrere Räder eines Fahrzeuges abzubremsen, so geht von diesem Flüssigkeitszylinder aus eine Ausgleichleitung zu den Zylindern der anderen Bremsen, um so auch in den anderen Bremsen die Hilfsbremsbacke anzuziehen.Brake force equalization device for brakes of motor vehicles Bei Vehicle brakes have already been proposed in addition to the main brake shoes, which are pushed against the part to be braked when the brakes are applied, a To arrange auxiliary brake shoe, which increases the braking effect, and this auxiliary brake shoe to be connected swingably by means of a lever with a main brake shoe. The present invention relates to a braking device having such Auxiliary jaw. However, the auxiliary jaw is not simply leveraged by the one main brake shoe pressed against the flange, but it is between Lever and auxiliary brake shoe arranged a cylinder filled with liquid, the transfers the lever pressure to the auxiliary brake shoe. Will this brake application used to brake several wheels of a vehicle at the same time, so goes from this liquid cylinder a compensating line to the cylinders of the other Brakes, in order to also pull the auxiliary brake shoe in the other brakes.

Abb. i zeigt schematisch eine derartige Bremsanordnung in Verbindung mit vier zu bremsenden Rädern.Fig. I shows schematically such a brake arrangement in connection with four wheels to be braked.

Abb. 2 zeigt eine Einzelanordnung, teilweise im Schnitt.Fig. 2 shows an individual arrangement, partly in section.

Die dargestellte Fahrzeugbremse wird hydraulisch in Bewegung gesetzt, indem von einem Zylinder i aus die Druckflüssigkeit zu einem in jeder Bremse angeordneten Zylinder 2 geschickt wird. Jede Bremse umfaßt die beiden Bremsbacken 3 und q., die bei Einschickung des Druckmittels in den Zylinder 2 gegen den Flansch 6 angedrückt werden.The vehicle brake shown is set in motion hydraulically, by arranging the hydraulic fluid from a cylinder i to one in each brake Cylinder 2 is sent. Each brake comprises the two brake shoes 3 and q., The pressed against the flange 6 when the pressure medium is sent into the cylinder 2 will.

An die Bremsbacke q. ist durch den Zapfen 7 eine Hilfsbremsbacke 5 angelenkt, und diese Backe wird von der Bremsbacke 3 aus beeinflußt, da ein Hebel 8 gelenkig mit dem Ende der Bremsbacke 3 verbunden ist und bei g in der Bremse schwingbar unterstützt ist. Dieser Hebel 8 trägt unter Vermittlung des Zapfens ii den Flüssigkeitszylinder io. In ihm spielt der Kolben 12, der seinerseits bei 13 mit der Hilfsbremsbacke verbunden ist, welch letztere durch eine Feder 14. für gewöhnlich nach einwärts gezogen wird, während die beiden Hauptbremsbacken 3 und q. durch eine Feder 15 gewöhnlich in Auslösestellung gehalten werden.To the brake shoe q. is an auxiliary brake shoe 5 through the pin 7 hinged, and this shoe is influenced by the brake shoe 3, as a lever 8 is articulated to the end of the brake shoe 3 and is swingable in the brake at g is supported. This lever 8 carries the liquid cylinder through the intermediary of the pin ii ok The piston 12 plays in it, which in turn plays at 13 with the auxiliary brake shoe is connected, the latter by a spring 14. Usually inwards is pulled while the two main brake shoes 3 and q. by a spring 15 usually be held in the release position.

Durch die Lagenveränderung der Bremsbacke 3, herbeigeführt durch Einschickung der Druckflüssigkeit in den Zylinder 2, erfährt der Hebel 8 eine Verstellung, so daß die Druckflüssigkeit in dem an diesem Hebel angelenkten Zylinder io auf den Kolben 12 wirkt und die Hilfsbremsbacke 5 nunmehr anstellt.By changing the position of the brake shoe 3, brought about by sending it in the pressure fluid in the cylinder 2, the lever 8 experiences an adjustment, so that the pressure fluid in the cylinder hinged on this lever io on the Piston 12 acts and the auxiliary brake shoe 5 now engages.

Der Zylinder io in jeder Bremse hat eine nach außen gehende Leitung 18, welche durch die Leitung 17 miteinander verbunden ist. Es werden also dadurch alle Bremsen gleichzeitig unter gleichmäßiger Beeinflussung der Hilfsbremsbacken angestellt.The cylinder io in each brake has an outgoing line 18, which are connected to one another by line 17. So it will be through this all brakes at the same time with equal influence on the auxiliary brake shoes employed.
