Abstract

The invention relates to an arrangement for the emergency operation of supporting systems according to the preamble of Claim 1. This arrangement is independent of the possibilities of failure of the hydraulic pressure and nevertheless has been minimised in cost and action time. In an exemplary embodiment, the construction and function is explained and described in connection with the entire system. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Stützeinrichtung für Fahrzeuge etc. gemäß dem Gattungsbegriff des Anspruchs 1.The invention relates to a support device for vehicles etc. according to the preamble of claim 1.

Solche Anordnungen sind in verschiedenen Ausführungsformen aus dem Stand der Technik bekannt. So offenbart die DE-PS 10 71 314 ein hydraulisches Stütz- und Stellorgan, das einen in einem Hydraulikzylinder geführten, mit einem Stützfuß versehenen Kolben aufweist und in diesem Stützzylinder eine Blockiereinrichtung für den Kolben angeordnet ist, die als nicht selbst­ hemmende Gewindespindel ausgebildet und mit einer Scheibenbremse verbunden ist. Bei Ausfall des Hydraulikdruckes ist das Stützsystem nicht mehr bewegbar. Die bisherigen Notverfah­ ren sind zumindest sehr umständlich, so muß beispielsweise der Hydraulik­ druck durch Handpumpe erzeugt werden.Such arrangements are in various embodiments from the prior art known in the art. So DE-PS 10 71 314 discloses a hydraulic Support and actuator, which is guided in a hydraulic cylinder with has a support leg provided piston and in this support cylinder Blocking device for the piston is arranged as not itself inhibiting threaded spindle and connected with a disc brake is. If the hydraulic pressure fails, the support system can no longer be moved. The previous emergency procedures Ren are at least very cumbersome, for example, the hydraulics pressure generated by hand pump.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Anordnung der eingangs genannten Art zu schaffen, die unabhängig von den Ausfallmöglich­ keiten des Hydraulikdruckes ist und bei Ausfall des Hydraulikdruckes über­ gangslos manuell betätigt werden kann.The present invention has for its object an arrangement of to create the type mentioned above, which is possible regardless of the failure hydraulic pressure and if the hydraulic pressure fails can be manually operated smoothly.

Diese Aufgabe wird durch die im Anspruch 1 aufgeführten Maßnahmen gelöst. Eine vorteilhafte Ausgestaltung ist im Anspruch 2 wiedergegeben und in der nachfolgenden Beschreibung ist ein Ausführungsbeispiel erläutert und in den Figuren der Zeichnung gezeigt. Es zeigen:This object is achieved by the measures listed in claim 1. An advantageous embodiment is shown in claim 2 and in the The following description explains an exemplary embodiment and in shown the figures of the drawing. Show it:

Fig. 1 eine schematische Gesamtdarstellung des als Ausführungsbei­ spiel beschriebenen Stützsystems; Fig. 1 is a schematic overall representation of the support system described as game Ausführungsbei;

Fig. 2 einen Querschnitt der Anordnung und Ausbildung des manuellen Notbetriebteils zum Stützsystem gemäß Fig. 1. FIG. 2 shows a cross section of the arrangement and design of the manual emergency operating part for the support system according to FIG. 1.

Die in der Fig. 1 gezeigte Stützeinrichtung setzt sich aus einem Stütz­ zylinder 22, einem Zylinderdeckel 12 und einem Stützfuß 23, einer Kugelge­ windespindel 16 und einer Bremseinrichtung 10 mit Bremskolben 19 und Bremsscheibe 15 zusammen. The support device shown in Fig. 1 is composed of a support cylinder 22 , a cylinder cover 12 and a support foot 23 , a Kugelge wind spindle 16 and a braking device 10 with brake piston 19 and brake disc 15 together.

Steht dieses Stützsystem unter Druck (der Last bzw. Hydraulik), so sind die Bremskolben 19 eingefahren und das Bremssystem ist entriegelt. Damit wird die Kolbenstange 11 des Stützzylinders 22, die über eine Kugelumlauf­ mutter 21 und Gewindespindel 16 mit der Bremseinrichtung 10 verbunden ist, freigegeben und die Kolbenstange 11 bzw. der hydraulische Stützzylinder 22 kann aus- und eingefahren werden. Unterbricht man nun die Ölzufuhr zu diesem Stützzylinder 22, so blockiert die Bremseinrichtung 10 sofort die Rotationsbewegung der Kugelgewindespindel 16 und damit auch eine Axialbe­ wegung der Kugelumlaufmutter 21 und der Kolbenstange 11. Hiermit ist der statische Zustand erreicht und die Stützlast wird nur noch mechanisch über die Kugelumlaufmutter 21 und die Gewindespindel 16 auf die Kolbenstange 11 übertragen.If this support system is under pressure (the load or hydraulics), the brake pistons 19 are retracted and the brake system is unlocked. So that the piston rod 11 of the support cylinder 22 , which is connected via a ball nut 21 and threaded spindle 16 to the braking device 10 , released and the piston rod 11 or the hydraulic support cylinder 22 can be extended and retracted. If you now interrupt the oil supply to this support cylinder 22 , the braking device 10 immediately blocks the rotational movement of the ball screw 16 and thus also an axial movement of the ball nut 21 and the piston rod 11 . The static state is hereby achieved and the vertical load is only transferred mechanically to the piston rod 11 via the ball nut 21 and the threaded spindle 16 .

Dieses System weist eine Reihe von Vorteilen auf. So kann es eine sehr hohe Last in jeder beliebigen Ausfahrposition des Stützzylinders 22 halten und nach Abschaltung des hydraulischen Systemdruckes mechanisch abstützen. Dadurch aber haben z.B. Temperaturschwankungen keinen Einfluß mehr auf die Druckverhältnisse in den Stützzylindern 22 bzw. in der hydraulischen Verrohrung. Weiterhin wird ein Absacken des abgestützten Fahrzeugs bei plötzlichem Rohrbruch oder bei Leckagen verhindert und ein ruckfreies An- oder Weiterfahren aus jeder beliebigen Position ermöglicht. Weiterhin kann durch Veränderung des Systemdruckes die Stützlast in weitem Bereich gegebenen Erfordernissen angepaßt werden, so daß durch den Vorteil des ruckfreien An- und Weiterfahrens eine gezielte Nivellierung ermöglicht wird.This system has a number of advantages. It can hold a very high load in any extension position of the support cylinder 22 and provide mechanical support after the hydraulic system pressure has been switched off. As a result, however, temperature fluctuations, for example, no longer have any influence on the pressure conditions in the support cylinders 22 or in the hydraulic piping. A sagging of the supported vehicle in the event of a sudden pipe break or leakage is prevented and jerk-free starting or continuing from any position is made possible. Furthermore, by changing the system pressure, the drawbar load can be adapted in a wide range to the given requirements, so that targeted leveling is made possible by the advantage of jerk-free starting and continuing.

In der Fig. 2 ist nun die Anordnung zum Notbetrieb des vorbeschriebenen Stützsystems in einem Ausführungsbeispiel gezeigt. Der manuelle Notbetrieb besteht aus einem Kegelradgetriebe 13, 14, bei dem das Kegelrad 13 über eine Bremsscheibe 15 mit der rotierenden Kugelgewindespindel 16 verbunden ist. Als Gegenlager für die Bremsscheibe 15 ist eine Lüftungsschraube 17 angeordnet.In FIG. 2, the arrangement is now shown for the emergency operation of the aforementioned support system in one embodiment. The manual emergency operation consists of a bevel gear 13 , 14 , in which the bevel gear 13 is connected to the rotating ball screw 16 via a brake disc 15 . A ventilation screw 17 is arranged as a counter bearing for the brake disc 15 .

Bei der Betätigung des Notbetriebes durch die Handkurbel 20 wird die Lüftungsschraube 17 gelöst und die Kugelgewindespindel 16 mit der Brems­ scheibe 15 frei beweglich. Mit der Handkurbel 20 - die als Bordwerkzeug sowieso jedem Fahrzeug beigegeben ist - wird das Ritzel 14 gegen den gefederten Bolzen 18 in die Verzahnung des Kegelrades 13 geschoben. Durch Rechts- oder Linksdrehung der Kurbel 20 wird der mit der Kugelumlaufmutter verbundene Hydraulikkolben aus- oder eingefahren. Durch Eindrehen der Lüftungsschraube 17 gegen den Anschlag wird die Gewindespindel 16 über die Bremsscheibe 15 wieder blockiert.When emergency operation is actuated by the hand crank 20 , the ventilation screw 17 is loosened and the ball screw 16 with the brake disc 15 is freely movable. With the hand crank 20 - which is included with every vehicle as an on-board tool anyway - the pinion 14 is pushed against the spring-loaded pin 18 into the toothing of the bevel gear 13 . By turning the crank 20 to the right or left, the hydraulic piston connected to the ball nut is extended or retracted. By screwing the ventilation screw 17 against the stop, the threaded spindle 16 is blocked again via the brake disc 15 .
