Description
Die Erfindung bezieht sich auf Kippvorrichtungen für Fahrzeuge, und zwar auf solche, bei denen in dem Rohrleitungssystem der hydraulischen Hubeinrichtung Senkventile vorgesehen sind. Gegenstand dieser Erfindung ist eine besondere Ausbildung der Abflußorgane der Hubpressen.The invention relates to tilting devices for vehicles, and although to those in which in the pipeline system of the hydraulic lifting device Lowering valves are provided. The subject of this invention is a special training the drainage organs of the lifting presses.
Es ist bekannt, Fahrzeugkippvorrichtungen gleichzeitig mit mehreren Hubpressen zu bedienen, deren Rückleitungen von einem gemeinsamen Rückflußventil abgesperrt werden. Diese bekannten Einrichtungen haben jedoch den großen Nachteil, daß bei unterschiedlicher Belastung der einzelnen Hubpressen ein Teil der Flüssigkeitsmenge aus der stärker belasteten Hubpresse in die schwächer belastete Hubpresse gedrückt wird, weil notgedrungen eine Vereinigung der Abflußleitungen vor dem gemeinsamen Ventil vorhanden ist. Dadurch tritt ein Verkanten der Ladebrücke ein, welches zu Verklemmungen und Beschädigungen derselben führt. Um Beschädigungen zu vermeiden, mußte die Ladebrücke daher sehr kräftig ausgeführt werden, was sich ungünstig auf die Herstellungskosten und das Gewicht des Fahrzeugs auswirkte.It is known to use vehicle tilting devices simultaneously with several Lift presses to operate, their return lines from a common return valve be locked. However, these known devices have the major disadvantage that with different loads on the individual lifting presses a part of the amount of liquid pressed from the more heavily loaded lifting press into the less loaded lifting press is, because of necessity a union of the drains before the common Valve is present. This causes the loading bridge to tilt, which leads to Jamming and damage of the same leads. To avoid damage, the loading bridge therefore had to be made very strong, which was unfavorable the manufacturing cost and weight of the vehicle.
Dieser Nachteil wird erfindungsgemäß dadurch beseitigt, daß für jede Hubpresse ein eigenes Absperrventil vorgesehen ist, die Abflußleitungen also einzeln abgesperrt sind. Damit beim Senken der Hubpresse kein ungleichmäßiges Öffnen der verschiedenen Ventile erfolgen kann, sind diese in einem Gehäuse erfindungsgemäß so angeordnet, daß sie zwangläufig gleichmäßig betätigt werden.This disadvantage is eliminated according to the invention in that for each Lifting press is provided with its own shut-off valve, so the drain lines individually are locked. So that when lowering the lifting press there is no uneven opening of the different valves can be made, these are in a housing according to the invention arranged so that they are inevitably operated evenly.
Im gemeinsamen Ventilgehäuse ist ein Steuerkolben mit Stiften angeordnet, die ihrerseits auf je ein federbelastetes Senkventil in den Rücklaufleitungen einwirken. Das Verschieben des Steuerkolbens kann mittels Handrad und Spindelschub oder mittels eines pneumatischen Preßmittels erfolgen.A control piston with pins is arranged in the common valve housing, which in turn act on a spring-loaded lowering valve in the return lines. The control piston can be moved by means of a handwheel and spindle thrust or by means of a pneumatic pressing means.
An Hand der Zeichnung ist die Erfindung beispielsweise dargestellt.The invention is illustrated by way of example with the aid of the drawing.
In einem gemeinsamen Gehäuse I sind erfindungsgemäß zwei Kugelventile 2 und 3 angeordnet, welche mittels Federn 4 und 5 auf den Sitz gedrückt werden. Im Gehäuse I ist ein Kolben. 6 geführt, welcher mittels einer Dichtung 7 gegen die Gehäusewand abgedichtet ist. Der Kolben hat zwei Stifte 8 und 9, welche derart an den Ventilen 2 und 3 anliegen, daß sie diese beim Verschieben des Kolbens gegen die Ventile gleichzeitig von ihren Sitzen abheben. Der Kolben 6 kann mittels des Handrades Io und der Gewindespindel II von Hand verstellt werden. Die Betätigung des Kolbens 6 kann auch mit Druckluft aus der Fahrzeugbremsanlage über die Leitung I2, das Steuerorgan I3 (welches eine Entlüftung ermöglicht) und die Leitung 14 erfolgen. Die zwei Hubpressen I5 und I6 stehen über Abflußleitungen I7 und I8 mit den Ventilkammern I9 und .2o in Verbindung. Der Raum 2I hinter den Ventilen steht durch eine Abflußleitung 22 mit dem Druckmittelsammelbehälter 23 in Verbindung.According to the invention, there are two ball valves in a common housing I 2 and 3, which are pressed onto the seat by means of springs 4 and 5. In the housing I is a piston. 6 out, which by means of a seal 7 against the Housing wall is sealed. The piston has two pins 8 and 9, which are so on the valves 2 and 3 rest against them when moving the piston lift the valves from their seats at the same time. The piston 6 can by means of Handwheel Io and the threaded spindle II can be adjusted by hand. The operation of the piston 6 can also be supplied with compressed air from the vehicle brake system via the line I2, the control element I3 (which allows ventilation) and the line 14 take place. The two lifting presses I5 and I6 are connected to the valve chambers via discharge lines I7 and I8 I9 and .2o in conjunction. The space 2I behind the valves is through a drain line 22 with the pressure medium collecting container 23 in connection.
Durch das Handrad Io oder Preßluftbeaufschlagung mittels des Steuerorgans I3 wird der Kolben 6 bewegt, welcher die Ventile 2 und 3 gleichmäßig betätigt. Dadurch erfolgt der Abfluß des Druckmittels aus den Hubpressen I5 und I6 vollkommen gleichmäßig. Das Druckmittel fließt durch die Ventile zum Druckmittelsammelbehälter 23. Eine Fernsteuerung von irgendeiner Stelle des Fahrzeuges aus ist mittels einer Druckluftschaltung möglich.By the handwheel Io or by applying compressed air by means of the control element I3 the piston 6 is moved, which actuates the valves 2 and 3 evenly. Through this the discharge of the pressure medium from the lifting presses I5 and I6 takes place completely evenly. The pressure medium flows through the valves to the pressure medium collecting container 23. A Remote control from anywhere in the vehicle is by means of a compressed air circuit possible.
Früher mußte man die Hubpressen I5 und I6 symmetrisch unterbringen, um eine möglichst gleichmäßige Lastverteilung auf die verschiedenen Hubpressen zu erreichen, damit Rahmenverbiegungen möglichst vermieden wurden. Die Erfindung ermöglicht nunmehr die unsymmetrische Anordnung der Hubpressen. Bei ungleichmäßiger Belastung der verschiedenen Hubpressen besteht keine Gefahr mehr, daß die stärker belastete Hubpresse absinkt und die weniger stark belastete Hubpresse ausfahren kann, so daß der Fahrzeugrahmen nicht verkanten kann.In the past, you had to accommodate the lifting presses I5 and I6 symmetrically, in order to distribute the load as evenly as possible to the various lifting presses so that frame bending was avoided as far as possible. The invention enables now the asymmetrical arrangement of the lifting presses. With uneven loading of the various lifting presses there is no longer any risk of the more heavily loaded Lifting press drops and the less heavily loaded lifting press can extend so that the vehicle frame cannot tilt.
