Abstract
Description
Die vorliegende Erfindung betrifft ein Hydrauliksystem, insbesondere für Kraftfahrzeuge, mit einem Geberzylinder, einem Nehmerzylinder, einer diese verbindenden Druckleitung und einer Dämpfungseinrichtung.The The present invention relates to a hydraulic system, in particular for motor vehicles, with a master cylinder, a slave cylinder, one of these connecting Pressure line and a damping device.
Zur Dämpfung bzw. Absorption von Schwingungen in hydraulischen Systemen werden Dämpfungseinrichtungen verwendet, die an einen Abzweig einer Hydraulikleitung angeschlossen werden. Derartige Dämpfungseinrichtungen umfassen meist ein oder mehrere Ventile und sind daher teuer in der Fertigung. Zudem lassen sich die Dämpfungs- bzw. Absorptionseigenschaften nur durch Änderungen z. B. von Gehäuseabmaßen oder durchströmten Querschnitten erreichen, sodass meist der Austausch von Teilen der Dämpfungseinrichtung zur Abstimmung nötig ist.to damping or absorption of vibrations in hydraulic systems attenuators used, which is connected to a branch of a hydraulic line become. Such damping devices usually include one or more valves and are therefore expensive in the production. In addition, the damping or absorption properties can be only through changes z. B. housing dimensions or perfused Cross sections, so that usually the replacement of parts of the attenuator necessary for the vote is.
Eine Aufgabe der Erfindung ist es, eine leicht herstellbare und leicht abstimmbare Dämpfungseinrichtung bereitzustellen.A The object of the invention is an easily produced and easy tunable damping device provide.
Dieses Problem wird gelöst durch ein Hydrauliksystem, insbesondere für Kraftfahrzeuge, mit einem Geberzylinder, einem Nehmerzylinder, einer diese verbindenden Druckleitung und einer Dämpfungseinrichtung, wobei die Dämpfungseinrichtung eine Schlauchleitung umfasst, die nach Art einer Blindleitung an einer Seite hydraulisch mit der Druckleitung verbunden ist und an der anderen Seite verschlossen ist. Über die Länge und Beschaffenheit, insbesondere Materialauswahl, der Schlauchleitung kann die gewünschte Dämpfung, insbesondere die zu dämpfende Mittenfrequenz, variiert werden. Die Schlauchleitung besteht aus einem flexiblen Material, beispielsweise Kunststoff oder Gummi jeweils mit oder ohne Armierung.This Problem is solved by a hydraulic system, in particular for motor vehicles, with a Master cylinder, a slave cylinder, a connecting this pressure line and a damping device, wherein the damping device is a Hose line comprises, in the manner of a stub on a Hydraulic side is connected to the pressure line and at the other side is closed. about the length and texture, in particular material selection, the hose line can the desired Damping, especially those to be damped Center frequency, can be varied. The hose consists of a flexible material, such as plastic or rubber, respectively with or without reinforcement.
Vorzugsweise ist vorgesehen, dass die hydraulische Verbindung der Schlauchleitung mit der Druckleitung ein metallisches Anschlussstück umfasst, auf das die Schlauchleitung aufgeschoben ist. Derartige Abzweige lassen sich relativ leicht in Druckleitungen hydraulischer Systeme, die meist aus Metallrohren bestehen, als T-förmige Abzweigung einfügen.Preferably is provided that the hydraulic connection of the hose line comprising a metallic connector with the pressure line, on which the hose is pushed. Such branches Can be relatively easily in pressure lines hydraulic systems, which usually consist of metal tubes, insert as a T-shaped branch.
Vorzugsweise ist vorgesehen, dass das Anschlussstück einen Schlauchnippel umfasst und die Schlauchleitung mittels einer Presshülse mit dem Schlauchnippel verbunden ist. Es handelt sich hier um eine Verbindung, die mit bekannten Werkzeugen leicht herzustellen ist.Preferably it is provided that the connector comprises a hose nipple and the tubing by means of a compression sleeve with the hose nipple connected is. This is a connection with known tools is easy to produce.
Vorzugsweise ist vorgesehen, dass der Schlauchnippel einen Begrenzungsbund umfasst. Dieser erleichtert die Montage, da vorgegebene Längen der Schlauchleitung leicht einzuhalten sind, indem diese bis zu dem Begrenzungsbund aufgeschoben wird.Preferably it is provided that the hose nipple comprises a boundary collar. This facilitates the assembly, since given lengths of the hose easy are to be adhered to by deferring them to the boundary collar becomes.
Vorzugsweise ist vorgesehen, dass an der verschlossenen Seite ein Stopfen in die Schlauchleitung eingeführt ist. Dies ist ein einfach zu fertigender Abschluss für die Schlauchleitung. Alternativ könnte dieser auch durch Verschweißen, Verkleben, Verpressen oder dergleichen hergestellt werden. Der Stopfen weist vorzugsweise einen Bereich nach Art eines Schlauchnippels, der in die Schlauchleitung eingeführt ist, und einen Anschlagteller auf. Dies ist eine leicht zu montierende Verbindung, die eine reproduzierbare hydraulische Länge der Dämpfungseinrichtung bei der Montage ermöglicht. Vorzugsweise ist der Stopfen mithilfe einer Presshülse mit der Schlauchleitung verbunden. Derartige Verbindungen sind durch standardisierte Bauteile einfach und kostengünstig herstellbar.Preferably is provided that on the closed side a plug in introduced the hose is. This is an easy-to-make finish for the tubing. Alternatively, this could be also by welding, Bonding, pressing or the like can be produced. The stopper preferably has a region in the manner of a hose nipple, which is inserted into the tubing, and a stop plate on. This is an easy-to-install compound that is a reproducible one hydraulic length the damping device allowed during assembly. Preferably, the plug is using a compression sleeve with connected to the hose. Such compounds are by standardized components simple and inexpensive to produce.
