Description
Die Erfindung betrifft einen Servomotor zur Veränderung· des Abstandes zweier Lagerstellen voneinander, der aus einem mit einer Lagerstelle gelenkig in Verbindung stehenden Zylinder besteht, in dem ein Kolben verschiebbar ist, dessen Kolbenstange mit der anderen Lagerstelle verbunden ist, insbesondere zum Verschwenken der Ladeschaufell von Ladegeräten. Derartige Servomotoren sind bekannt. Sie werden beispielsweise bei Ladegeräten benutzt, um den Ausleger und die Ladeschaufel zu verschwenken. Soll der Ausleger einer solchen Lademaschine verschwenkt, beispielsweise gehoben werden, so führt man an dem unteren Ende des Servomotors ein Druckmittel zu, wodurch das auf der anderen Seite des Kolbens vorhandene Druckmittel aus dem Zylinder an dessen anderem Ende ausströmt. Soll der Ausleger gesenkt werden, dann spielt sich der Vorgang in umgekehrter Folge ab. Beim Heben des Auslegers wird also Druck auf die Seite des Kolbens des Servomotors ausgeübt, deren Fläche dem Querschnitt des Zylinders entspricht. Das dem Heben des Auslegers dienende zugeführte Druckmittel übt also eine maximale Kraft auf den Kolben aus. Da das Heben mehr Kraft erfordert als das Senken, wird das erreicht, was erreicht werden soll. Würde man diesen Servomotor in gleicher Gestaltung auch für das Verschwenken der Ladeschaufel verwenden, dann ergibt sich der Nachteil, daß das dem Heben dienende Druckmittel dort zuzuführen ist, wo die Fläche des Kolbens um den Querschnitt der Kolbenstange verringert wird, d. h., der Druck ist auf die weniger wirksame Seite des Kolbens auszuüben. Dementsprechend erfolgt das Heben der Ladeschaufel mit verhältnismäßig geringer Kraft, aber verhältnismäßig großer Geschwindigkeit. Soll die Schaufel gesenkt, also entleert werden,, dann wirkt das Druckmittel auf die Fläche des Kolbens, die der Querschnktsfläche .des Zylinders: entspricht. Das Entleeren wird also mit verhältnismäßig großer Kraft und mit verhältnismäßig geringer Geschwindigkeit durchgeführt.The invention relates to a servomotor for changing the distance between two bearing points, which consists of a cylinder articulated with a bearing point, in which a Piston is displaceable, the piston rod is connected to the other bearing, in particular to Pivoting the loading shovel of chargers. Such servomotors are known. you will be used for example in chargers to pivot the boom and the loading shovel. Should he The boom of such a loading machine is pivoted, for example lifted, so one leads to the lower end of the servomotor to a pressure medium, whereby the existing on the other side of the piston Pressure medium flows out of the cylinder at its other end. Should the boom be lowered then the process takes place in reverse order. When the boom is raised, there is pressure exerted on the side of the piston of the servomotor, the area of which corresponds to the cross-section of the cylinder. The pressure medium supplied to lift the boom thus exerts a maximum force the piston off. Because lifting requires more force than lowering, what will be achieved is what will be achieved target. If this servo motor would also be used in the same design for pivoting the loading shovel use, then there is the disadvantage that the pressure medium used for lifting must be supplied there is where the area of the piston is reduced by the cross section of the piston rod, i.e. h., the Pressure should be applied to the less effective side of the piston. The lifting takes place accordingly Loading shovel with relatively little force, but relatively high speed. Intended to the shovel is lowered, ie emptied, then the pressure medium acts on the surface of the piston, which the Cross-section area of the cylinder: corresponds to. The emptying is therefore carried out with relatively great force and carried out at a relatively low speed.
Der Erfindung liegt die Aufgabe zugrunde, diesen Nachteil zu vermeiden. Erfindungsgemäß wird vorgeschlagen, den Zylinder des Servomotors mit der einen Lagerstelle, über seitlich der Kolbenstange angeordnete Gleitbahnen in Verbindung stehen zu lassen und das Ende der Kolbenstange des im Zylinder verschiebbaren Kolbens über seitlich des Zylinders angeordnete Streben od. dgl. mit der anderen Lagerstelle zu verbinden und die sich gegeneinander bewegenden Teile des Servomotors so zu führen, daß sie sich ständig wenigstens annäherungsweise längs einer Geraden bewegen, die durch die Achsen der Lagerstellen festgelegt ist. Es empfiehlt sich, das Ende der Kolbenstange so anzuordnen, daß es in allen Stellungen des Kolbens Servomotor,The invention is based on the object of avoiding this disadvantage. According to the invention it is proposed the cylinder of the servomotor with one bearing point, arranged on the side of the piston rod Let slideways stand in connection and the end of the piston rod of the slidable in the cylinder To connect the piston to the other bearing point via struts or the like arranged on the side of the cylinder and to guide the mutually moving parts of the servomotor so that they are constantly move at least approximately along a straight line defined by the axes of the bearing points is. It is advisable to arrange the end of the piston rod so that it is in all positions of the piston Servo motor,
