Description
Koordinatenschalter Die Erfindung richtet sich auf einen Koordinatenschalter zur B dienung zweier unter einem rechten Winkel zueinander gehäusefest angeordneter Drehschalter mittels eines in zwei Koordinatenrichtungen und jeder resultierenden Richtung beweglichen, mit einer Gelenkkugel versehenen Steuerhebels, dessen Bewegungen auf die Schalterwellen übertragbar sind, wobei in jeder Koordinatenrichtung jeweils nur eine der beiden Schalterwellen gedreht wird.Coordinate switch The invention is directed to a coordinate switch to serve two fixed to the housing at a right angle to each other Rotary switch means one in two coordinate directions and each resulting Direction of moving control lever with a ball joint, its movements can be transferred to the switch shafts, in each case in each coordinate direction only one of the two switch shafts is rotated.
Es ist bereits ein derartiger Koordinatenschalter bekannt, bei dem die Gelenkkugel, wie auch sonst an Kugelschaltern üblich, in der Ebene der Frontplatte gelagert ist, und in dem Gehäuseinnern des Schalters befindet sich der andere Hebelarin des Steuerhebels, der an je einem Kurbelzapfen zweier Kurbelantriebe angreift, die auf die beiden Schalterwellen zweier Schalter arbeiten. Jeder der beiden Schalter hat seinen eigenen Drehantrieb. Da aber die Angriffspunkte des inneren Hebelarms des Steuerhebels von der Kugelmitte bis zu den Kurbelzapfen verschieden lange Hebelanne aufweisen, ergeben sich ungleiche Drehwinkel der Kurbelantriebe bei gleichem Ausschlag des Steuerhebels in der einen oder der anderen Koordinatenrichtung. Weitere Ungleichheiten des bekannten Schalters ergeben sich aus der Sinusbewegung der Kurbeltriebe. Somit kann der eine Steuerhebel wohl in Koordinatenrichtungen und resultierenden Richtungen bewegt werden, wenn es beispielsweise darum geht, zwei Motoren derart zu steuern, daß jeder von ihnen unabhängig vom anderen ein- und ausgeschaltet und gegebenenfalls in seiner Drehrichtung, umgeschaltet werden kann, ohne daß der eingestellte Betriebszustand des anderen Motors beeinflußt wird. Es ist aber nicht möglich, bei dem bekannten Schalter die einzelnen Stellen des Steuerhebels in der einen und in der anderen Drehrichtung bei übereinstimmenden Drehwinkeln beider Schalter mittels einfacher, gleich ausgebildeter Drehrastwerke, deren Rastabstände untereinander gleich sind, eindeutig zu rasten, um Stufenschalter verwenden zu können, deren Schaltkombinationen den Koordinatenstellungen des Steuerhebels entsprechen.It is already known such a crossbar, which is as well supported otherwise on ball switches common in the plane of the front plate, the ball joint, and in the housing interior of the switch is the other Hebelarin the control lever, the two at a respective crank pin crank drives attacks that work on the two switch shafts of two switches. Each of the two switches has its own rotary actuator. However, since the points of application of the inner lever arm of the control lever from the center of the ball to the crank pin have lever arm lengths of different lengths, unequal angles of rotation of the crank drives result with the same deflection of the control lever in one or the other coordinate direction. Further inequalities of the known switch result from the sinusoidal movement of the crank mechanisms. Thus, one control lever can be moved in coordinate directions and resulting directions, for example, when it comes to controlling two motors in such a way that each of them can be switched on and off independently of the other and, if necessary, in its direction of rotation, can be switched without the the set operating state of the other motor is influenced. However, with the known switch it is not possible to clearly lock the individual positions of the control lever in one and the other direction of rotation at the same angle of rotation of the two switches by means of simple, identically designed rotating detents whose detent distances are equal to each other in order to be able to use tap changers whose switching combinations correspond to the coordinate positions of the control lever.
Es ist weiter eine Einhebel-Lenksteuervorrichtung bekannt, bei der eine drehbewegliche Haube zur Lagerung des gabelförmig ausgebildeten Steuerhebels C el dient, der fest mit den in der Haube gelagerten Achsbolzen verbunden ist. Der gabelförmig ausgebildete Steuerhebel umgreift die Haube. Innerhalb der Haube sind, ebenfalls mit den Achsbolzen fest verbunden, weitere Hebel vorgesehen, zwischen welchen eine Rolle gelagert ist, die in eine Schlitzkurbel eingreift, welche ihrerseits mit einer Schubstange starr verbunden ist. Dadurch ist es möglich, die Schwenkbewegung des gabelförmig ausgebildeten Steuerhebels auf die Schubstange zu übertragen, die eine Auf- und Abbewegung ausführt, welche nun ihrerseits wiederum durch weitere Mittel ' nämlich eine zweite Schlitzkurbel, eine zweite Rolle und an einen Ansatz eines zweiten Zahnsegmentes auf ein Kegelrad übertragen wird, welches mit der Drehachse eines Walzenschalters verbunden ist. Das erste Zahnsegnient- treibt über ein Ritzel die Welle eines zweiten Walzenschalters.Furthermore, a single-lever steering control device is known in which a rotatable hood serves to support the fork-shaped control lever C el, which is firmly connected to the axle bolts mounted in the hood. The fork-shaped control lever engages around the hood. Further levers are provided inside the hood, also firmly connected to the axle bolts, between which a roller is mounted, which engages in a slotted crank, which in turn is rigidly connected to a push rod. This makes it possible to transfer the pivoting movement of the fork-shaped control lever to the push rod, which executes an up and down movement, which in turn now by further means , namely a second slotted crank, a second roller and a shoulder of a second toothed segment on a Bevel gear is transmitted, which is connected to the axis of rotation of a roller switch. The first serrated tooth drives the shaft of a second roller switch via a pinion.
Diese bekannte Vorrichtung ist daher verhältnismäßig kompliziert und zeigt ein erhebliches Spiel, das durch die Bewegungsluft innerhalb der verschiedenen miteinander zusammenwirkenden Getriebeteile bestimmt ist. Daher können auch die erzielten Schaltstellungen nicht sehr genau sein. Weiterhin ist es nachteilig, daß die verschiedenen Schaltstellungen infolge der Drehung der Haube auf einer Zylinderinantelfläche liegen. Aus diesem Grund ist die bekannte Einhebel-Lenksteuervorrichtung durch die sogenannten Kugelschalter überholt, bei denen sich die Bewegung des Schaltstiles eindeutig in einer Ebene vollzieht. Trotz dieses Vorteils haben Kugelschalter den Nachteil, daß sie stets über Schubglieder auf entsprechende Schalter wirken, daß die Zahl der Kombinationsschaltungen verhältnismäßig gering ist und daß sie hinsichtlich ihrer baulichen Mittel verhältnismäßig aufwendig sind.This known device is therefore relatively complicated and shows a considerable amount of play created by the air movement within the various cooperating gear parts is determined. Therefore, the achieved switching positions not be very accurate. Furthermore, it is disadvantageous that the different switching positions as a result of the rotation of the hood on a cylinder jacket surface lie. For this reason, the known single lever steering control device is by the so-called ball switches obsolete, in which the movement of the switching style clearly takes place in one plane. Despite this advantage, ball switches have the Disadvantage that they always act on corresponding switches via push members that the number of combination circuits is relatively small and that they with respect to their structural means are relatively expensive.
Der Erfindung liegt die Aufgabe zugrunde, den Koordinatenschalter der eingangs erwähnten Art so zu verbessern, daß mittels einfacher Drehrastwerke eine eindeutige Rasterung erzielt werden kann.The invention is based on the object of the crossbar switch of the type mentioned to improve so that by means of simple rotary latches a clear grid can be achieved.
C3 Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß zwei sich kreuzende und aneinander vorbeigehende Bügel der beiden Schalterwellen die Gelenkkugel des Steuerhebels in der Mittenebene derselben tra-en und mittels rechtwinklig zueinanderstehender Stiftpaare mit der Kugel drehbeweglich in Wirkungsverbindung sind, von denen das eine Stiftpaar des Bügels in der Kugel sitzt und das andere Stiftpaar des zweiten Bügels in eine Umfangsnut derselben eingreift. Mit diesen an sich sehr einfachen Mitteln ist gewährleistet, daß die betreffenden Stufeneinstellungen der Schalter in jeder Raststellung des Steuerhebels auch tatsächlich erreicht werden, wobei sich bei Verwendung eines Stufenschalters mit je zwei Stellungen zu beiden Seiten der Nullstellung bereits fünfundzwanzig eindeutige Schaltstellungen für Kombinationssehaltungen ergeben. C3 To solve this problem, the invention provides that two crossing and passing brackets of the two switch shafts meet the joint ball of the control lever in the center plane of the same and are rotatably connected to the ball by means of pairs of pins at right angles to one another, one of which is a pair of pins The bracket sits in the ball and the other pair of pins of the second bracket engages in a circumferential groove of the same. With this in itself very simple means it is guaranteed that the respective stages settings of the switches will be achieved in each detent position of the control lever, with a step switch with two positions result already twenty-five distinct switching positions for Kombinationssehaltungen when using both sides of the zero position.
Die Erfindung ermöglicht es, handelsübliche, bereits mit Rastwerken versehene Stufenschalter in Verbindung mit dem erfindungsgemäßen Koordinatenschalter zu verwenden, wobei dann die Rastwerke dieser Schalter gleichzeitig die Raststellungen des Steuerhebels bestimmen. Dadurch sind eigene Rastwerke für den Schalter entbehrlich, und es genügt, in jeder Frontplatte eine quadratische Öffnung ohne jede Schaltkulisse anzuordnen.The invention makes it possible to use commercially available, already with locking mechanisms provided step switches in connection with the coordinate switch according to the invention to use, in which case the locking mechanisms of these switches are also the locking positions of the control lever. As a result, separate locking mechanisms for the switch are unnecessary, and it is sufficient to have a square opening in each front panel without any switching gate to arrange.
Dar-über hinaus entfällt die bei dem erwähnten bekannten Schalter noch erforderliche gesonderte Lagerung der Gelenkkugel. Die Aufhängung dieser Kugel unmittelbar zwischen den beiden Schalterwellen ist insofern einfacher, als die hier verwendeten Schaltbügel nicht nur die beiden komplizierteren und doppelseitig gelagerten Kugeltriebe ersetzen, sondern auch gleichzeitig die Kugel in ihrer Mittenebene halten.In addition, the known switch mentioned in the case of the aforementioned is omitted Separate storage of the joint ball that is still required. The suspension of this ball directly between the two switch shafts is easier than this one used switch bracket not only the two more complicated and double-sided Replace ball drives, but also keep the ball in its center plane at the same time.
In weiterer Ausgestaltung der Erfindung kann vorgesehen sein, daß ein Schenkel des einen Bügels mit einer Öffnung für den Schenkel des anderen Bügels versehen ist. Ferner können die Bügel in einem Kupplungstell einer Steckkupplung enden, in den die Schalterwelle mit einem Gegenkupplungsteil eingreift.In a further embodiment of the invention it can be provided that one leg of one bracket with an opening for the leg of the other bracket is provided. Furthermore, the bracket can be a plug-in coupling in a coupling end, in which the switch shaft engages with a mating coupling part.
Nach einem weiteren vorteilhaften Merkmal der Erfindung kann vorgesehen sein, daß die Schaltstellungen des Steuerhebels durch die Rastwerke der verwendeten Stufenschalter innerhalb einer quadratischen Öffnung der Frontplatte bestimmt sind.According to a further advantageous feature of the invention, provision can be made be that the switching positions of the control lever are used by the locking mechanisms Step switches are intended within a square opening in the front panel.
Weitere Vorteile und Einzelheiten der Erfindung ergeben sich aus der nun folgenden Beschreibung eines Ausführungsbeispiels unter Hinweis auf die Zeichnung. In dieser zeigt F i 1-. 1 eine Seitenansicht des Koordinatenschalters, F i g. 2 eine Draufsicht auf den Koordinatenschalter nach F i g# 1 im Schnitt A -B, F i g. 3 eine Seitenansicht zur F i g. 1 in Richtung des Pfeiles C und F i g. 4 eine schematische Darstellung der Schaltstellungen gemäß den Koordinatenschnittpunkten. An der Frontplatte 1 sitzen Montagewinkel 2 für den Stufensschalter 3 mit den beiden Schalterwellen 4, die in den Schaltern gelagert sind. Die Schalter haben wie üblich Rastwerke 5, welche die eigenen Schaltstellungen rasten. Diese Stufenschalter sind nicht Gegenstand der Erfindung. Sie sind bekannt und deshalb nicht im einzelnen weiter beschrieben.Further advantages and details of the invention emerge from the following description of an exemplary embodiment with reference to the drawing. In this shows F i 1-. 1 shows a side view of the crossbar, FIG. 2 is a plan view of the crossbar switch according to FIG. 1 in section A- B, FIG. 3 is a side view of FIG. 1 in the direction of arrow C and F i g. 4 shows a schematic representation of the switching positions according to the coordinate intersections. On the front panel 1 are mounting brackets 2 for the multiple switch 3 with the two switch shafts 4, which are mounted in the switches. As usual, the switches have locking mechanisms 5, which lock their own switch positions. These tap changers are not the subject of the invention. They are known and are therefore not further described in detail.
Die Schaltenvellen 4 der Stufenschalter 3 stehen rechtwinklio, zueinander und sind zugleich die Achsen eines Kardangelenkes, dessen Teil die Pfanne 6 ist, in der die Gelenkkugel 7 des Schaltstiels 8 mit Kugelgriff 9, wie bei Kugelschaltem üblich, beweglich ist im tD und die aus zwei Hälften zusammengeschraubt ist Für die kardanische Aufhängung der Kugel 7 dienen zwei mit den Schalterwellen 4 verbundene Bügel 10 und 11. Der Bügel 11 ist gleichbleibend breit und durchgreift mit seinem linken Schenkel (F i g. 2) den hinteren Schenkel des Bügels 10, der als Rahmen 10 a mit der Öffnung 10 b ausgebildet ist. Der Bügel 10 greift über die beiden Stifte 12, die fest in der Kugel 7 sitzen, die eine Ringnut 13 besitzt. In diese Ringnut greifen Stifte 14 gleitend ein, die in Augen 15 der Pfanne 6 befestigt sind und an ihrem freien äußeren Enden den Bügel 11 tragen. Die Bügel 10 und 11 sind auf ihren Stiften schwenkbar.The switching shafts 4 of the tap changer 3 are perpendicular to each other and are at the same time the axes of a universal joint, part of which is the socket 6 , in which the joint ball 7 of the switching handle 8 with ball handle 9, as usual with ball switches, is movable in the tD and the two halves screwed together for the gimbal suspension of the ball 7 are two connected with the switch shafts 4 bow 10 and 11. the bracket 11 is constant width and extends with his left leg (F i g. 2) the rear leg of the bracket 10 which as Frame 10 a is formed with the opening 1 0 b . The bracket 10 engages over the two pins 12, which are firmly seated in the ball 7 , which has an annular groove 13 . Pins 14, which are fastened in the eyes 15 of the pan 6 and carry the bracket 11 at their free outer ends, slide into this annular groove. The brackets 10 and 11 are pivotable on their pins.
Die Steckkupplung 16 besteht aus der Kupplungshülse 17, die mit jedem der beiden Bügel 10, 11 fest verbunden ist und einen Schlitz 18 für einen Stift 19 aufweist, der in der Schalterwelle 4 sitzt. Das Ende der Schalterwelle 4 mit dem Stift 19 ist in die Kupplungshülse 17 mit Paßsitz einfügbar. An Stelle des offenen Schlitzes 18 können die Kupplungshülse und die Schalterwelle auch eine durchgehende Bohrung haben, in die der Stift 19 einsetzbar ist.The plug-in coupling 16 consists of the coupling sleeve 17, which is firmly connected to each of the two brackets 10, 11 and has a slot 18 for a pin 19 that sits in the switch shaft 4. The end of the switch shaft 4 with the pin 19 can be inserted into the coupling sleeve 17 with a snug fit. Instead of the open slot 18 , the coupling sleeve and the switch shaft can also have a through hole into which the pin 19 can be inserted.
Die Pfanne 6 mit der Kugel 7 des Schaltstiels 8 werden- mittels ihrer kardanischen Aufhängung allein durch die beiden rechtwinklig zueinander angeordneten Schalterwellen 4 gehalten. Für die erforderliche Beweglichkeit des Schaltstiels besitzt die Frontplatte 1 eine quadratische Öffnung 20, die an dem fertig montierten Kugelschalter irgendwie abgedeckt ist, sei es durch eine bewegliche, die Öffnung in jeder Stellung überdeckende Scheibe oder einen Gummibalg.The socket 6 with the ball 7 of the switch handle 8 are held by means of their cardanic suspension solely by the two switch shafts 4 arranged at right angles to one another. For the required mobility of the switch handle, the front plate 1 has a square opening 20, which is somehow covered on the fully assembled ball switch, be it by a movable disc covering the opening in every position or a rubber bellows.
In F i g. 4 sind die Schaltebenen der beiden Schalter mit 1, 11 und 0 bezeichnet. Nach dem fiktiven Koordinatennetz ergibt sich an jedem Koordinatenschnittpunkt eine Schaltstellung. Insgesamt sind vierundzwanzig Schaltstellungen und eine Nullstellung vorhanden.In Fig. 4, the switching levels of the two switches are labeled 1, 11 and 0 . According to the fictitious coordinate network, there is a switch position at each coordinate intersection. There are a total of twenty-four switch positions and one zero position.
