Description

Gle% . . " -se Die vorliegende Erfindung betrifft eine Verbesserung der Gleisbremse nach dem Patent 621 812. Nach diesem Patent wird die Höhe des Bremszylinders so bemessen, daß der Luftdruck in dem Maße steigt, wie der Kniehebel steiler wird. Dieser Zylinderraum ist daher höher, als es zum Bewegen der Bremsschienen zwischen der Bereitschafts-und Bremsstellung nötig ist; er gebraucht daher namentlich beim Umsteuern von der Bereitschafts- in die Bremsstellung mehr Druckluft. Gle%. . "-se The present invention relates to an improvement of the track brake according to patent 621 812. According to this patent, the height of the brake cylinder is dimensioned so that the air pressure increases as the toggle becomes steeper. This cylinder space is therefore higher than is necessary to move the brake rails between the standby and braking positions; he therefore needs more compressed air, especially when changing the direction from the standby to the braking position.

Der Zweck der Erfindung ist, die Bewegungen des Gestänges und der Bremsbalken zwischen Bereitschafts- und Bremsstellung möglichst klein zu halten und damit den Druckluftverbraüch im Bremszylinderraum zu vermindern.The purpose of the invention is to control the movements of the linkage and the Keeping the brake bar as small as possible between the standby and braking positions and thus to reduce the compressed air consumption in the brake cylinder space.

Nach der Abbildung, welche ein Ausführungsbeispiel zeigt, erhält der Zylinder für den Bremskolben 9 eine Höhe, die ausreicht, die Bremsbalken zwischen der Bremsstellung I und der Bereitschaftsstellung II zu bewegen. Dicht übendem unteren Hubkolben 8 ist ein Zylinder 12 angeschlossen, in dem ein Kolben 13 unter dem Druck einer Feder 14 liegt. Diese Feder wird so bemessen *und vorgespannt, daß sie unter dem höchsten einstellbaren Luftdruck in der Stellung I nicht nachgibt. Der beim Durchlaufen der Fahrzeuge ausweichende Bremsbalken drückt durch die Stellstangen Ija den Bremskolben 9 herab und verkleinert den Raum unter dem Bremskolben, wobei Druckluft in den Zylinder 12 tritt und damit den unter Federspannung stehenden Kolben 13 zurückdrängt. Die Feder 14 ist so bemessen, daß hierbei ihre Spannung in solchem Maße zunimmt, daß der Bremsdruck der Balken bei den verschiedenen Steigungen der Stellstangen II und Ija nahezu unverändert bleibt.According to the figure which shows an exemplary embodiment, the Cylinder for the brake piston 9 a height sufficient to hold the brake beam between the braking position I and the ready position II to move. Tightly practicing lower Reciprocating piston 8 is connected to a cylinder 12 in which a piston 13 is under pressure a spring 14 is located. This spring is dimensioned and preloaded so that it is under does not yield to the highest adjustable air pressure in position I. The at As the vehicles pass through, the evasive brake beam pushes through the control rods Ija the brake piston 9 down and reduces the space under the brake piston, wherein Compressed air enters the cylinder 12 and thus the spring-loaded piston 13 pushes back. The spring 14 is dimensioned so that here its tension in such The extent to which the brake pressure of the bars increases with the various slopes of the Control rods II and Ija remains almost unchanged.

Der Zylinder 12 kann sowohl neben dem Hauptzylinder, wie die Abbildung zeigt, als auch in den Bremskolbenraum, beispielsweise in den Boden des Bremskolbens, eingebaut werden.The cylinder 12 can be both next to the master cylinder, as shown in the figure shows, as well as in the brake piston space, for example in the bottom of the brake piston, to be built in.
