Abstract
Description
Die Erfindung bezieht sich auf Traktorwegeventile für Hydrauliksteuerungen, die getrennt von den zugehörigen Hydraulikkupplungen angeordnet sind bzw. auf Traktorwegeventile, an denen Kupplungen bzw. Kupplungsvorbauten direkt angeflanscht sind, wobei mehrere zu einem Block aneinander geflanschte Traktorwegeventile vorgesehen sein können.The The invention relates to tractor travel valves for hydraulic controls separate from the associated Hydraulic couplings are arranged or on tractor valves, where couplings or coupling stems are directly flanged, wherein a plurality of flanged to a block tractor valves can be provided.
Traktorwegeventile mit getrennt angeordneten Hydraulikkupplungen bieten die Möglichkeit weitere Wegeventile dazwischen anzuordnen, um gezielt zusätzliche Verbraucher, beispielsweise Frontlader, mit Drucköl zu versorgen und dabei unkontrollierte Bewegungen gleichzeitig angeschlossener Verbraucher zu vermeiden, eine gewisse Leckageneigung ist bei dieser Ausführung nicht vollständig auszuschließen.Tractor-way valves with separately arranged hydraulic couplings provide the opportunity to arrange further directional valves in between to specifically additional To supply consumers, for example front loaders, with pressurized oil while doing uncontrolled movements simultaneously connected Consumers to avoid a certain leakage tendency is at this execution not completely excluded.
Traktorwegeventile mit direkt angeflanschten Kupplungen bzw. Kupplungsvorbauten haben den Vorteil eines insgesamt kompakten Aufbaus, geringerer Leckageneigung und reduzierter Herstellkosten.Tractor-way valves have directly flanged couplings or coupling stems the advantage of a total compact design, lower leakage tendency and reduced manufacturing costs.
In der Praxis sind die beiden vorgenannten Traktorwegeventil-Ausführungen mehrfach bekannt.In In practice, the two aforementioned tractor valve versions known several times.
Ziel der vorliegenden Erfindung ist es, vorgenannte Traktorwegeventile mit direkt angeflanschten Kupplungen bzw. Kupplungsvorbauten für weitere Funktionen preiswert und möglichst leckagefrei nutzbar zu machen.aim The present invention is the aforementioned tractor directional valves with directly flanged couplings or coupling stems for further functions inexpensive and possible to be used without leakage.
Gemäß der vorliegenden Erfindung wird dies dadurch erreicht, dass zwischen mindestens einem Traktorwegeventil und den zugeordneten Kupplungen in Flanschbauweise mindestens ein Wegeventil mit Anschlüssen für zusätzliche Verbraucher montiert ist, wobei die an das Traktorwegeventil angeflanschten Kupplungen bzw. Kupplungsvorbauten von dem Traktorwegeventil abgebaut und am Wegeventil montiert sind. Durch dieses direkte Anflanschen des Wegeventils sowie der Kupplungen bzw. Kupplungsvorbauten wird eine besonders kompakte Bauform erreicht, die in einfacher Weise eine zusätzliche Nutzung des betreffenden Traktorwegeventils ermöglicht, außerdem werden durch dieses direkte Aneinanderflanschen sonst mögliche Leckagen nahezu ausgeschlossen.According to the present Invention this is achieved in that between at least one tractor valve and the associated couplings in flange construction at least one Directional valve with connections for additional Consumer is mounted, with the flanged to the tractor directional valve Clutches or coupling stems dismantled from the tractor-way valve and are mounted on the directional control valve. By this direct flanging the directional control valve and the clutches or coupling stems is achieved a particularly compact design, in a simple manner an additional Use of the relevant tractor way valve also allows through this direct flanges otherwise possible leaks almost impossible.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass zwischen zwei oder mehr Traktorwegeventilen und den zugeordneten Kupplungen eine entsprechende Anzahl Wegeventile mit Anschlüssen für zusätzliche Verbraucher montiert ist. Es können dadurch mehrere Verbraucher gleichzeitig angeschlossen werden, wodurch ein besonders effektiver Nutzungsgrad für die betreffenden Traktorwegeventile bei gleichzeitig äußerst kompakter Bauform derselben erreicht.In Another embodiment of the invention is provided that between two or more tractor valves and associated couplings one corresponding number of directional control valves with connections for additional consumers mounted is. It can thereby several consumers are connected simultaneously, thereby a particularly effective degree of utilization for the relevant tractor directional valves at the same time extremely compact Design of the same achieved.
Gemäß der Erfindung ist ferner vorgesehen, dass das zusätzliche Wegeventil und der Kupplungsvorbau in einer Einheit zusammengefasst sind, wobei diese Einheit schraubbar an dem Traktorwegeventil bzw. den Traktorwegeventilen befestigt ist. An diese Einheit werden dann auch die zuvor von dem Traktorwegeventil abgebauten Kupplungen wieder angeschraubt. Insbesondere bei mehreren zu einem gemeinsamen Block zusammengefassten Traktorwegeventilen ist eine solche Einheit aus Wegeventilen und Kupplungsvorbau besonders vorteilhaft einbaubar.According to the invention is further provided that the additional directional control valve and the Coupling stem are combined in one unit, these Unit can be screwed to the tractor-way valve or the tractor-way valves is attached. To this unit then also the previously of the Tractor way valve dismantled couplings screwed back. Especially in the case of several tractor-way valves combined to form a common block Such a unit of directional control valves and coupling stem is particularly can be installed advantageously.
In bevorzugter Ausführungsform ist das zusätzliche Wegeventil bzw. sind die zusätzlichen Wegeventile elektrisch zu- und abschaltbar. Das erforderliche Zu- bzw. Abschalten ist bei dieser Ausführungsform in einfacher Weise durch Betätigen entsprechender Schalter realisierbar. Grundsätzlich ist jedoch auch eine Lösung denkbar, bei der ein mechanisches Zu- und Abschalten des zusätzlichen Wegeventils bzw. der Wegeventile erfolgt.In preferred embodiment is the extra Directional valve or are the additional Directional control valves electrically switched on and off. The required Shutdown is in this embodiment in a simple manner by pressing corresponding switch realized. Basically, however, is also one solution conceivable, in which a mechanical switching on and off of the additional Directional valve or the directional valves takes place.
Die Erfindung sieht ferner vor, dass mindestens ein zusätzliches Wegeventil werksseitig durch den Traktorhersteller installiert ist. Eine solche werksseitige Installation von zusätzlichen Wegeventilen erspart ein späteres Nachrüsten, außerdem sind die betreffenden Traktorwegeventile durch eine solche Ausstattung mit zusätzlichen Wegeventilen von Anfang an besonders vielseitig nutzbar.The The invention further provides that at least one additional Directional control valve is factory installed by the tractor manufacturer. Such a factory installation of additional directional valves saves a later one retrofitting, Furthermore are the relevant tractor valves by such equipment with additional Directional valves from the beginning particularly versatile.
Die Erfindung ist an Ausführungsbeispielen in der Zeichnung dargestellt und wird im folgenden näher erläutert.The The invention is based on embodiments in the drawing and will be explained in more detail below.
