Description
Die Erfindung betrifft ein Fahrzeug, insbesondere ein land- oder bauwirtschaftliches Fahrzeug, gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a vehicle especially a country or construction vehicle, according to the preamble of the claim 1.
Aus der nicht vorveröffentlichten
Aus der gattungsbildenden
Die
Nachteil eines derart bekannten Fahrzeugs ist, dass auf das Sperrglied aufgrund des. Vorhandenseins des Querlenkers relativ hohe Kräfte wirken. Das Sperrglied ist aus diesem Grund entsprechend groß zu dimensionieren. Dies wirkt sich nachteilhaft auf die Bedienungs- und Betätigungseinrichtungen, wie Leitungen für das Sperrglied aus.The disadvantage of such a known vehicle is that on the locking member due to the presence of the wishbone relatively high forces Act. For this reason, the locking member must be dimensioned accordingly large. This has a disadvantageous effect on the operating and operating devices, such as Lines for the locking member.
Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, ein Fahrzeug vorzuschlagen, bei welchem das Sperrglied möglichst wenig Bauraum beansprucht, vorteilhaft auf die Bedienungs- und Betätigungseinrichtungen wirkt und vor Beschädigungen und Verschmutzungen geschützt ist.The present invention lies therefore based on the task of proposing a vehicle in which the locking member if possible takes up little space, advantageous for the operating and operating devices acts and against damage and dirt is protected is.
Diese Aufgabe wird bei einem Fahrzeug mit den Merkmalen des Patentanspruchs 1 gelöst.This task is done on a vehicle solved with the features of claim 1.
In Weiterbildung der Erfindung ist der als Hydraulikzylinder ausgebildete Zylinder ein Plungerzylinder und das Ventil als ein 3/2-Wegeventil ausgebildet. Diese Ausbildung stellt einen einfachen Aufbau dar, der kostengünstig ist und aufgrund der Verbindung mit der druckgebenden Einrichtung keine Fremdspeisung benötigt. Der Plungerzylinder ist leicht und schnell sperrbar. Darüber hinaus ist, insbesondere bei einer Nachrüstung mit der hydraulischen Blockierung, ein geringer Montage- und Installationsaufwand gegeben.In development of the invention the cylinder designed as a hydraulic cylinder is a plunger cylinder and the valve is designed as a 3/2-way valve. This training represents a simple structure that is inexpensive and due to the No external power supply in connection with the pressure device needed. The plunger cylinder can be locked quickly and easily. Furthermore is, especially when retrofitting with hydraulic locking, there is little assembly and installation effort.
In Weiterbildung der Erfindung ist der als Hydraulikzylinder ausgebildete Zylinder ein Gleichlaufzylinder, dessen Steuervolumina über das elektrisch betätigbare Ventil zur Blockierung der Achse voneinander trennbar sind, wobei die druckgebende Einrichtung entfällt. Neben dem Vorteil, dass ein derart ausgebildeter Hydraulikzylinder ebenfalls leicht und schnell sperrbar ist, ist der Vorteil gegeben, dass bei der Verwendung eines Gleichlaufzylinders die druckgebende Einrichtung (Ausgleichsspeicher) entfällt.In development of the invention the cylinder designed as a hydraulic cylinder is a synchronous cylinder, whose tax volumes over the electrically operated Valve for blocking the axis are separable, wherein the printing device is omitted. Besides the advantage that a hydraulic cylinder designed in this way is also light and fast is lockable, there is the advantage that when using a Synchronizing cylinder the pressure-generating device (compensation memory) eliminated.
In Weiterbildung der Erfindung ist das Ventil als 4/9-Wegeventil ausgebildet. In dieser Ausgestaltung ist es möglich, in Ergänzung zu dem Ventil eine Pumpe und einen Rücklauf zu verwenden, so dass ein Heben bzw. Senken der Achse gegenüber einem Fixpunkt möglich ist.In development of the invention the valve as a 4/9-way valve educated. In this configuration, it is possible to supplement the valve to use a pump and a return, so that a It is possible to raise or lower the axis relative to a fixed point.
In Weiterbildung der Erfindung ist zwischen dem Ventil und dem als Hydraulikzylinder ausgebildeten Zylinder zumindest eine Drossel vorgesehen. Die Verwendung einer Drossel hat den Vorteil, dass bei der Federung [insbesondere der Aus- bzw. Einfederung] eine Dämpfung gegeben ist. Aufgrund der Verwendung entsprechend ausgebildeter Drosselstellen kann die Dämpfung variiert werden. Ebenso ist es denkbar, eine Drosselung nur in einer Richtung (in einer Leitung von dem Ventil zu dem Zylinder) vorzusehen, so dass die Dämpfung richtungsabhängig ist.In development of the invention between the valve and the hydraulic cylinder Cylinder provided at least one throttle. The use of a Throttle has the advantage that the suspension [especially the Deflection] given is. Due to the use of appropriately trained Throttling points can damping can be varied. It is also conceivable to throttle only in one Direction (in a line from the valve to the cylinder), so the damping is directional.
In Weiterbildung der Erfindung ist zwischen dem Ventil und dem als Hydraulikzylinder ausgebildeten Zylinder zumindest ein Rückschlagventil vorgesehen, wobei in vorteilhafter Weise zumindest eine Drossel und das zumindest eine Rückschlagventil parallel geschaltet sind. Damit ist ebenfalls eine sichere Blockierung gegeben, die mit einer Dämpfung versehen ist.In development of the invention between the valve and the hydraulic cylinder Cylinder at least one check valve provided, advantageously at least one throttle and that at least one check valve in parallel are switched. This also ensures a safe blocking, which provide damping is.
In Weiterbildung der Erfindung ist der Hydraulikzylinder derart ausgestaltet, dass er bei Blockierung die gesamte auf die Achse wirkende Kraft (Last) aufnimmt. Diese Auslegung des Hydraulikzylinders Stellt einen Sicherheitsfaktor dar, so dass die Blockierung bei maximaler Last sichergestellt ist.In development of the invention the hydraulic cylinder designed such that it is blocked absorbs the entire force (load) acting on the axis. This Design of the hydraulic cylinder Provides a safety factor so that blocking at maximum load is ensured.
Weitere Ausgestaltungen der Erfindung sind im folgenden näher beschrieben und in den Figuren gezeigt:Further refinements of the invention are closer below described and shown in the figures:
