Description

Die Erfindung betrifft eine Vorrichtung zum Steuern und insbesondere zum Steuern der Fahrbewegungen eines Raupenfahrzeuges mit einem um mindestens eine Achse schwenkbaren und/oder rotierenden Steuerhebel.The invention relates to a device for controlling and in particular for Control the movement of a caterpillar vehicle with at least one an axis pivotable and / or rotating control lever.

Steuerhebel der hier interessierenden Art sind bekannt und können bei Raupenfahrzeugen unmittelbar zur Steuerung von Servoeinrichtungen dienen. Es handelt sich dort um eine Vorsteuerung für die eigentliche Hydrauliksteuerung, die zum Beispiel zum Vorwärtsfahren und Rückwärtsfahren sowie für die Gegenrotation der Raupen zum Schwenken des Raupenfahrzeuges benötigt wird. Bei den bekannten Vorrichtungen muß der Fahrer den Steuerhebel in seiner gedrückten Position ununterbrochen halten. Sobald er den Steuerhebel losläßt, fährt er selbsttätig in seine neutrale Mittelposition zurück. Dies ist für viele Anwendungsfälle unzweckmäßig, so daß der Erfindung die Aufgabe zugrunde liegt, einfache und kostengünstig herstellbare Maßnahmen vorzusehen, die es gestatten, daß der Steuerhebel auch dann in einer gedrückten Stellung stehen bleibt, wenn der Fahrer die Hand vom Steuerhebel nimmt.Control levers of the type of interest here are known and can be used for Tracked vehicles for direct control of servo devices serve. It is a pilot control for the actual hydraulic control, for example for driving forward and backward as well as for the counter rotation of the caterpillars for swiveling the caterpillar vehicle is needed. In the known devices, the Driver continuously hold the control lever in its depressed position hold. As soon as he releases the control lever, he automatically moves into his neutral middle position back. This is inappropriate for many applications, so that the invention is based on the task simple and to provide measures which can be produced cost-effectively and which allow that the control lever remains in a depressed position, when the driver takes his hand off the control lever.

Zur Lösung dieser Aufgabe sieht die Erfindung vor, daß die Stellung des Steuerhebels magnetisch fixierbar ist. Der Fahrer kann daher den Steuerhebel loslassen, ohne daß sich dadurch die eingestellten Fahrbewegungen ändern.To achieve this object, the invention provides that the position of the Control lever is magnetically fixable. The driver can therefore use the control lever Let go without the set travel movements to change.

Vorzugsweise ist der Steuerhebel elektromagnetisch sowie gegen mindestens eine an ihm angreifende Rückstellkraft fixierbar, wobei die Größe der zum Fixieren dienenden Kraft derart bemessen ist, daß der Steuerhebei dennoch jederzeit von Hand verstellbar ist.The control lever is preferably electromagnetic and at least against a restoring force acting on it can be fixed, the size the force used to fix it is such that the control can still be adjusted by hand at any time.

Weitere Merkmale der Erfindung gehen aus den Unteransprüchen und der Beschreibung im Zusammenhang mit der Zeichnung hervor.Further features of the invention emerge from the subclaims and Description in connection with the drawing.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispieles, das in der Zeichnung dargestellt ist, näher beschrieben. Dabei zeigen:

partly in section and in side view the device for controlling;
Fig. 2:
a plan view of the device of FIG. 1 approximately along the line II - II and
Fig. 3:
a section through essential parts of the device on a larger scale.

Eine Vorrichtung 1 umfaßt gemäß Fig. 1 einen Steuerhebel 2, der um eine Achse 3 schwenkbar angeordnet ist. Eine Steuerglocke 4 ist mit dem Steuerhebel 2 über eine Stange 5 starr verbunden und überträgt die Bewegungen des Steuerhebels 2 auf Steuerstifte 6 und 7, die zu einer hier nicht näher interessierenden Servoeinrichtung 8 wie zum Beispiel einer hydraulischen Vorsteuereinrichtung zum Vor- und Rückwärtsfahren bzw. für die Gegenrotation von Raupen eines Raupenfahrzeuges gehören.1, a device 1 comprises a control lever 2, which is a Axis 3 is pivotally arranged. A control bell 4 is with the Control lever 2 rigidly connected via a rod 5 and transmits the movements of the control lever 2 on control pins 6 and 7, to one here Servo device 8 of no interest, such as, for example hydraulic pilot control device for driving forwards and backwards or belong to the counter-rotation of caterpillars of a caterpillar vehicle.

Ebenfalls starr mit dem Steuerhebel 2 ist ein Mitnehmer 9 verbunden, der in der Lage ist, die Bewegungen des Steuerhebels 2 um die Achse 3 auf einen Lenker 10 zu übertragen. Der Mitnehmer 9 ist gemäß Ausführungsbeispiel hülsenförmig und umgreift die Steuerglocke 4. Der Lenker 10 ist an dem Mitnehmer 9 zum Beispiel mit Hilfe eines Kugelkopfes angelenkt. Eine Schutzhülle 11 umgreift die Teile 3, 4, 5, 6 und 7 sowie 9.A driver 9 is also rigidly connected to the control lever 2 is able to move the control lever 2 about the axis 3 to transmit a handlebar 10. The driver 9 is according to the embodiment sleeve-shaped and surrounds the control bell 4. The handlebar 10 is articulated on the driver 9, for example with the aid of a ball head. A protective cover 11 encompasses parts 3, 4, 5, 6 and 7 and 9.

Der Lenker 10 ist mit seinem dem Mitnehmer 9 abgewandten Ende 12 mit einem Kupplungselement 13 verbunden. Das Kupplungselement 13 umfaßt eine Ringscheibe 14 mit einem Arm 15, an dem der Lenker 10 unmittelbar angelenkt ist.The handlebar 10 is with its end 12 facing away from the driver 9 a coupling element 13 connected. The coupling element 13 comprises an annular disc 14 with an arm 15 on which the handlebar 10 directly is articulated.

Dem Kupplungselement 13 ist ein Elektromagnet 16 zugeordnet. Über elektrische Leiter 17 und 18 wird eine Spule bzw. eine elektrische Wicklung 19 in einem Gehäuse 20 zur Erzeugung eines elektromagnetischen Feldes erregt. Aufgrund dieses elektromagnetischen Feldes ist sodann auch eine dem Kupplungselement 13 zugewandte Stirnfläche 21 des Gehäuses 20 magnetisch und nach dem Ausschalten des Stromes unmagnetisch. Mit einem Flansch 22 und Befestigungselementen 23 ist das Gehäuse 20 des Elektromagneten 16 an einem Winkelträger 24 befestigt. Das Kupplungselement 13 und der Elektromagnet 16 sind wesentliche Teile einer Haltevorrichtung 26 für den Steuerhebel 2.An electromagnet 16 is assigned to the coupling element 13. about electrical conductor 17 and 18 becomes a coil or an electrical winding 19 in a housing 20 for generating an electromagnetic Field excited. Because of this electromagnetic field is then also an end face 21 of the housing facing the coupling element 13 20 magnetic and non-magnetic after switching off the power. With a flange 22 and fasteners 23 is the housing 20 of the electromagnet 16 attached to an angle bracket 24. The Coupling element 13 and the electromagnet 16 are essential parts a holding device 26 for the control lever 2.

Gemäß dem in Fig. 3 dargestellten Ausführungsbeispiel weist der Winkelträger 24 eine Durchtrittsöffnung 25 auf, durch die Teile der Haltevorrichtung 26 greifen, zu der der Elektromagnet 16 und das Kupplungselement 13 gehören.According to the embodiment shown in Fig. 3, the angle bracket 24 a passage opening 25 through which parts of the holding device 26 reach to which the electromagnet 16 and the coupling element 13 belong.

Gemäß dem in Fig. 3 dargestellten Ausführungsbeispiel befindet sich eine weitere Durchtrittsöffnung 27 in dem Gehäuse 20 und dient zur Aufnahme einer einen Flansch aufweisenden Hülse 28. Die Hülse 28 besteht zweckmäßigerweise aus einem unmagnetischen Werkstoff.According to the embodiment shown in Fig. 3 there is one further passage opening 27 in the housing 20 and is used for receiving a sleeve 28 having a flange. The sleeve 28 expediently consists made of a non-magnetic material.

Im Inneren der Hülse 28 befindet sich eine Lagerschale 29, die zur Aufnahme einer Achse 30 dient, die gemäß Ausführungsbeispiel eine Schraube ist. Die Achse 30 bzw. Schraube durchgreift die Ringscheibe 14 des Kupplungselementes 13 und liegt sodann in der Lagerschale 29 und ist mit Hilfe einer Beilegscheibe und einer Mutter 31 in dem Gehäuse 20 gegen axiale Verschiebung gesichert. Dazu tragen auch Flansche an der Hülse 28 und der Lagerschale 29 bei, die das Gehäuse 20 auf der dem Kupplungselement 13 abgewandten Seite hintergreifen.In the interior of the sleeve 28 there is a bearing shell 29 which is for receiving an axis 30 is used, which according to the embodiment is a screw is. The axis 30 or screw passes through the washer 14 of the Coupling element 13 and is then in the bearing shell 29 and is with With the help of a washer and a nut 31 in the housing 20 against axial displacement secured. Flanges on the sleeve 28 also carry this and the bearing shell 29, which the housing 20 on the coupling element 13 reach behind the opposite side.

Gehäuseseitig weist das Kupplungselement 13 noch einen Ringkörper 32 auf, der an der Stirnfläche 21 des Gehäuses 20 anliegt und fest mit dem Kupplungselement 13 verbunden ist. On the housing side, the coupling element 13 also has an annular body 32 on, which abuts the end face 21 of the housing 20 and firmly with the Coupling element 13 is connected.

In der Ruhestellung gemäß Fig. 3 befindet sich ein Luftspalt zwischen der Stirnfläche 21 des Gehäuses 20 und dem Ringkörper 32. Dieser Luftspalt 33 kann 0,5 mm betragen.3 there is an air gap between the End face 21 of the housing 20 and the ring body 32. This air gap 33 can be 0.5 mm.

Zweckmäßiger Weise besteht der Ringkörper 32 aus dem gleichen Werkstoff wie er für Bremsbacken von Fahrzeugen verwendet wird.The ring body 32 expediently consists of the same material as used for vehicle brake shoes.

Sobald der Steuerhebel 2 aus der in Fig. 1 dargestellten Mittellage in eine andere Position gedrückt wird, nimmt auch das Kupplungselement 13 eine andere Lage ein. Die Spule 19 bzw. Wicklung des Elektromagnet 16 ist an eine Batterie angeschlossen und steht unter Strom. Sie kann ein- und ausgeschaltet werden. Der Elektromagnet 16 erzeugt daher ein elektromagnetisches Feld, durch das sich das Kupplungselement 13 mit seinem Ringkörper 32 in der durch die Verstellung des Steuerhebels 2 erreichten Lage fixieren läßt. Die Stärke des Elektromagneten 16 ist derart gewählt, daß der Steuerhebel 2 in jeder fixierten Stellung dennoch von Hand verstellbar ist. In der Regel üben die Steuerstifte 5 und 7 eine Rückstellkraft auf den Steuerhebel 2 aus. Sobald der Motor des Raupenfahrzeuges abgestellt bzw. der Strom ausgeschaltet wird, ist auch der Elektromagnet 16 wieder stromlos, so daß sich der Steuerhebel 2 spätestens dann auch aus einer magnetisch fixierten Position automatisch in seine Nullstellung bewegt.As soon as the control lever 2 from the central position shown in Fig. 1 in a other position is pressed, the coupling element 13 also takes one different location. The coil 19 or winding of the electromagnet 16 is on a battery is connected and is live. You can one and turned off. The electromagnet 16 therefore generates an electromagnetic one Field through which the coupling element 13 with its Ring body 32 in the reached by the adjustment of the control lever 2 Can fix position. The strength of the electromagnet 16 is chosen such that the control lever 2 is still adjustable by hand in any fixed position is. As a rule, the control pins 5 and 7 exert a restoring force on the control lever 2. As soon as the engine of the caterpillar is switched off or the current is switched off, the electromagnet 16 is also again without current, so that the control lever 2 then at the latest a magnetically fixed position automatically moves to its zero position.

Die Erfindung ist nicht auf das in den Figuren dargestellte Ausführungsbeispiel konkret beschränkt, vielmehr können auch noch Änderungen vorgenommen werden, ohne von den grundsätzlich Erfindungsgedanken abzuweichen. Dazu gehört auch, daß mehrere Elektromagnete anstelle von einem einzigen benutzt werden.The invention is not based on the embodiment shown in the figures concretely limited, rather changes can be made without deviating from the basic ideas of the invention. This also means that several electromagnets instead of one only be used.
