Description
Die vorliegende Erfindung betrifft eine Anordnung zur Druckregelung einer Getriebestelleinrichtung, gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to an arrangement for pressure control a gear-adjusting device, according to the preamble of patent claim 1.
Aus dem Stand der Technik ist bekannt, in Getriebestelleinrichtungen eine Druckmodulation durchzuführen. Hierbei erfolgt die Druckregelung über mindestens ein 2/2-Wege-Ventil, welches eine Durchlassrichtung "Entlüften" aufweist, wobei der Druck des Hauptabschaltventils über einen Drucksensor erfasst wird.Out The prior art is known in gearbox facilities to perform a pressure modulation. Here, the pressure is controlled by at least one 2/2-way valve, which has a passage direction "venting", wherein the pressure of the main shut-off valve is detected by a pressure sensor becomes.

Durch die Forderung nach geringeren Schaltzeiten sowie durch die Notwendigkeit einer gleichbleibenden bzw. geringeren Belastung der mechanischen Schaltelemente ist ein variabel einstellbarer Druck innerhalb der Schalteinrichtung bzw. der Getriebestelleinrichtung erforderlich. Hierbei kann durch die aus dem Stand der Technik bekannte Druckmodulation immer nur ein höherer Druckwert als momentan vorhanden eingeregelt werden.By the demand for shorter switching times as well as the necessity a constant or lower load on the mechanical Switching elements is a variably adjustable pressure within the Switching device or the gearbox device required. This can be achieved by the known from the prior art pressure modulation always just a higher one Pressure value to be set as currently available.
Andererseits ist bei den aus dem Stand der Technik bekannten Konstruktionen eine Entlüftung der Getriebestelleinrichtung bzw. des Getriebestellers nur auf aufwändige Art und Weise möglich, beispielsweise über Ventilkom binationen, was in nachteiliger Weise in einer hohen Belastung der Ventile und der mechanischen Schaltelemente resultiert. Da innerhalb einer Schaltung in zwei aufeinanderfolgenden Schaltphasen eine Druckregelung von einem hohen auf einen niedrigen Druck erforderlich sein kann, ist es vorteilhaft, wenn die Getriebestelleinrichtung auch gezielt entlüftet werden kann.on the other hand is in the constructions known from the prior art one Vent the Gearbox device or the gear plate only in a complicated way and way possible, for example about Ventilkom combinations, which disadvantageously in a high load the valves and the mechanical switching elements results. There within a circuit in two successive switching phases, a pressure control from high to low pressure may be required it is advantageous if the transmission device are also vented targeted can.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Anordnung zur Druckregelung einer Getriebestelleinrichtung anzugeben, welche eine gezielte Entlüftung bzw. Druckreduzierung der Getriebestelleinrichtung ermöglicht.Of the present invention is based on the object, an arrangement to specify for pressure control of a transmission device, which a targeted ventilation or pressure reduction of the transmission device allows.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere erfindungsgemäße Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.These The object is solved by the features of claim 1. Further Embodiments of the invention and advantages are apparent from the dependent claims.
Demnach wird eine Anordnung zur Druckregelung einer Getriebestelleinrichtung vorgeschlagen, umfassend zumindest einen Schaltzylinder, wobei jeder Druckraum des zumindest einen Schaltzylinders über eine Druckmittelleitung mit jeweils einem Schaltventil verbunden ist und wobei die Schaltventile über eine Druckluftversorgungsleitung und entsprechende Druckmittelleitungen mit einem mit einem Druckspeicher zur Druckluftversorgung verbundenen Hauptabschaltventil verbunden sind, bei der zur gezielten Entlüftung der Getriebestelleinrichtung ein Ventil mit Durchlassrichtung Entlüften vorgesehen ist, welches der gezielten regelbaren Entlüftung bzw. Druckreduzierung dient.Accordingly, an arrangement for pressure control of a transmission device is proposed, comprising at least one shift cylinder, each pressure chamber of the at least one shift cylinder is connected via a pressure medium line, each with a switching valve and wherein the switching valves via a compressed air supply line and corresponding pressure medium lines with a connected to a pressure accumulator for compressed air supply Hauptabschaltventil are connected, in which for the purpose of venting the gearbox device a valve is provided with venting passage, which the targeted controllable venting or pressure reduction is used.
Vorzugsweise ist das zusätzliche Ventil als 2/2-Wege-Ventil mit Durchlassrichtung Entlüften ausgebildet, welches an die Druckversorgungsleitung zwischen dem Hauptabschaltventil der Getriebestelleinrichtung und den Schaltventilen angeschlossen ist.Preferably is the extra Valve designed as a 2/2-way valve with bleed-off direction, which to the pressure supply line between the Hauptabschaltventil the gear setting device and the switching valves is connected.
Durch die erfindungsgemäße Erweiterung der Druckmodulation durch das 2/2-Wege-Ventil mit Durchlassrichtung Entlüften kann der Getriebesteller in allen Phasen gezielt entlüftet werden. Des weiteren resultiert die erfindungsgemäße Konzeption in einer besseren Regelbarkeit des Systemdrucks in der Getriebestelleinrichtung, so dass engere Toleranzen ermöglicht werden.By the expansion of the invention Pressure modulation through the 2/2-way valve with passage direction bleed The gearbox can be specifically vented in all phases. Furthermore, the inventive concept results in a better Controllability of the system pressure in the gearbox device, so that allows tighter tolerances become.
Ein weiterer Vorteil besteht darin, dass die Entlüftung der Getriebestelleinrichtung im Vergleich zu Entlüftungsmethoden, die aus dem Stand der Technik bekannt sind, einen geringeren Aufwand erfordert. Zudem werden durch die erfindungsgemäß erzielbare gezielte Entlüftung Leckagen reduziert, da ein andauerndes Nachregeln bei undichten Ventilen vermieden wird.One Another advantage is that the venting of the transmission device compared to venting methods, which are known from the prior art, a lower cost requires. In addition, the inventively achievable targeted ventilation leaks reduced, as a constant readjustment avoided in leaking valves becomes.
Die Erfindung wird im Folgenden anhand der beigefügten Figur, welche eine schematische Ansicht einer Anordnung zur Druckregelung einer Getriebestelleinrichtung darstellt, beispielhaft näher erläutert.The Invention will be described below with reference to the accompanying figure, which is a schematic View of an arrangement for pressure control of a transmission device represents, exemplary closer explained.
