Description

Vorrichtung zum Erzeugen von periodischen Druckschwankungen in hydraulischen Bremsbetätigungsanlagen, insbesondere für Kraftfahrzeuge Die Erfindung betrifft eine Vorrichtung zum Erzeugen von periodischen Druckschwankungen in hydraulischen Bremsbetätigungsanlagen, insbesondere für Kraftfahrzeuge. Durch derartige Vorrichtungen soll eine möglichst starke Bremswirkung unter Vermeidung des Blockierens der Fahrzeugräder erzielt werden.Device for generating periodic pressure fluctuations in hydraulic Brake actuation systems, in particular for motor vehicles The invention relates to a device for generating periodic pressure fluctuations in hydraulic Brake actuation systems, in particular for motor vehicles. By such devices is intended to have the greatest possible braking effect while avoiding the locking of the vehicle wheels be achieved.

Bekannt sind hydraulische Bremsbetätigungsanlagen, bei welchen im Bremsrohrsystem mit Hilfe einer Kolben- und Zylinderanlage periodische Druckschwankungen erzeugt werden. Der Antrieb erfolgt zumeist mit Hilfe einer rotierenden Nockenwelle oder durch ein Hebelgestänge, welches den Kolben in eine Hin- und Herbewegung versetzt. Neben dem verhältnismäßig hohen Aufwand derartiger Einrichtungen ergibt sich der Nachteil, daß es kaum gelingt, kurze und kräftige Druckimpulse zu erzeugen.Hydraulic brake actuation systems are known in which im Brake pipe system with the help of a piston and cylinder system, periodic pressure fluctuations be generated. The drive is mostly carried out with the help of a rotating camshaft or by a lever linkage, which sets the piston in a reciprocating motion. In addition to the relatively high cost of such facilities, there is also the Disadvantage that it is hardly possible to generate short and powerful pressure pulses.

Um diese Mängel zu vermeiden, wird gemäß der Erfindung vorgeschlagen, den Kolben mittels eines elektromagnetischen Hammerwerkes, z. B. nach dem Prinzip des Wagnerschen Hammers, anzutreiben. Hierbei werden kräftige kurze Impulse ausgelöst, die sich nach Art der Schallwellen in dem hydraulischen System bis zu den Bremsbacken hin fortpflanzen.In order to avoid these deficiencies, it is proposed according to the invention, the piston by means of an electromagnetic hammer mechanism, e.g. B. according to the principle of the Wagner hammer. Here, powerful short impulses are triggered, which are based on the type of sound waves in the hydraulic system up to the brake shoes to propagate.

Die Zeichnung zeigt einen Wagnerschen Hammer a, der auf einen Kolben b einwirkt. Dieser Kolben befindet sich in dem Zylinder c, welcher an das Bremsrohrsystem angeschlossen ist. Der Kolben b kann auch durch eine entsprechend dimensionierte Membran ersetzt werden.The drawing shows a Wagner hammer a, which hits a piston b acts. This piston is located in cylinder c, which is connected to the brake pipe system connected. The piston b can also be dimensioned accordingly Membrane to be replaced.
