Description

Kugelkopfkupplung für Bowdenzüge Ball coupling for Bowden cables
Die Erfindung betrifft eine Kugelkopfkuppiung für Bowdenzüge, insbesondere zur Herstellung einer Verbindung zwischen Stell- und Regelgliedern in Kraftfahrzeugen, wobei der Bowdenzug mit einem eine Kugelpfanne aufweisenden Endstück und das Stell- bezw. Regelglied mit einem in der Kugelpfanne gehaltenen Kugelkopf versehen sind.The invention relates to a ball head coupling for Bowden cables, in particular for establishing a connection between actuators and control members in motor vehicles, the Bowden cable with an end piece having a ball socket and the actuating or. Control element are provided with a ball head held in the ball socket.
Bei den beknannten Kugelkopfkupplungen für den genannten Zweck sind der Öffnungsdurchmesser der im wesentlichen geschlossenen Kugelpfanne und der Durchmesser des Kugelkopfes derart aufeinander abgestimmt, daß der Kugelkopf bei Nutzung der Materialelastizität mit einer bestimmten Kraft zum Einschnappen in die Pfanne gebracht werden kann und nach dem Einrasten oder Einschnappen frei gleitend in ihr gehalten ist. Der Nachteil der bekannten Bowdenzugkupplungen ist insbesondere darin zu sehen, daß ihre Montage, Justierung und gegebenenfalls Demontage dann erhebliche Schwierigkeiten verursachen, wenn der Einsatz - wie regelmäßig im Motorraum von Kraftfahrzeugen - unter beengten Raumverhältnissen und/oder an schwer zugänglichen Stelleu erfolgen muß. Die Ursache hierfür ist darin zu sehen, daß zur Gewährleistung einer ausreichend festen Verbindung die Dimensionierung der Kugelpfannenüffnung und des Kugelkopfes so stark überlappend erfolgen muß, daß zur Erreichung des Finschnappens ein erheblicher Krafteinsatz erforderlich wird, der unter beengten Platzverhältnissen und an einer schwer zugänglichen Stelle nur schwer aufgebracht werden kann. Dasselbe gilt verstärkt für den Fall, daß eine Demontage des Bowdenzuges erforderlich wird, die die in diesem Falle aufzubringenden Zugkräfte noch weseentlich schwerer aufgebracht werden können. Hinzu kommt, daß bei mehrmaliger Montage und Demontage Ausarbei tungen - im Allgemeinen an der aus Kunststoff bestehenden Kugelpfanne - auftreten, durch die die Haltekraft der Verbindung geschwächt wird, so daß nach bereits wenigen derartigen Montagen der Bowdenzug vollständig ausgewechselt werden muß.In the known ball head couplings for the stated purpose, the opening diameter of the substantially closed ball socket and the diameter of the ball head are matched to one another in such a way that the ball head can be snapped into the pan with a certain force when the material elasticity is used and after snapping in or snapping in is freely floating in it. The disadvantage of the known Bowden cable couplings can be seen in particular in the fact that their assembly, adjustment and, if necessary, disassembly cause considerable difficulties when the use - as is regularly the case in the engine compartment of motor vehicles - has to take place in a confined space and / or in difficult to access locations. The reason for this can be seen in the fact that to ensure a sufficiently firm connection, the dimensioning of the ball socket opening and the ball head must be so overlapping that a considerable amount of force is required to achieve the fin snap, which is necessary in confined spaces and can be applied only with difficulty in a place that is difficult to access. The same applies increasingly in the event that disassembly of the Bowden cable becomes necessary, since the tensile forces to be applied in this case can be applied even more difficult. In addition, with repeated assembly and disassembly elaborations - generally on the ball socket made of plastic - occur, by which the holding force of the connection is weakened, so that the Bowden cable must be replaced completely after only a few such assemblies.
Der vorliegenden Erfindung liegt als Aufgabe die Schaffung einer Bowdenzugverbindung zugrunde, die einerseits eine einfache Montage und Demontage ermöglicht und andererseits eine allen betrieblichen Anforderungen in Bezug auf ihre Festigkeit genügende Verbindung gewährleistet. Die Erfindung besteht darin, daß die Kugelpfanne von einer Kugelkalotte geringer, d.h. die Länge eines Kugelhalbmessers unterschreitender Höhe gebildet ist und der Kugelkopf auf der der Kugelkalotte abgewendeten Seite von einem Gegenlager umfaßt wird, das an einem sich parallel zur Mittelebene des Kugelkopfes erstreckenden, seitlich federnden Steg gehalten ist, wobei der Federsteg nach der Einsteckseite des Kugelkopfes hin aus der Mittelebene versetzt ist und das Gegenlager den Kugelkopf auf der der Einstecköffnung gegenüberliegenden Seite umfaßt.The present invention has for its object to provide a Bowden cable connection which on the one hand enables easy assembly and disassembly and on the other hand ensures a connection that meets all operational requirements with regard to its strength. The invention consists in that the ball socket is smaller from a spherical cap, i.e. The length of a height less than a spherical diameter is formed and the spherical head on the side facing away from the spherical cap is surrounded by a counterbearing which is held on a laterally resilient web which extends parallel to the central plane of the spherical head, the spring bar extending towards the insertion side of the spherical head the central plane is offset and the counter bearing comprises the ball head on the side opposite the insertion opening.
Durch die Erfindung ist eine Bowdenzugverbindung geschaffen, die einerseits einfach montierbar und demontierbar ist und andererseits eine allen betrieblichen Anforderungen in Bezug auf ihre Festigkeit genügt.The invention provides a Bowden cable connection which is easy to assemble and disassemble on the one hand and on the other hand meets all operational requirements in terms of its strength.
Durch die Wirkverbindung zwischen der Kalotte einerseits und der an einem federnden Steg befestigten und den Kugelkopf auf der der Kalotte gegenüberliegenden Seite haltenden Gegenlagers andererseits kann das Gegenlager beim Einstecken des Kugelkopfes zum Zwecke der Montage leicht nach der Seite ausgebogen werden, so daß die Montage mit geringstem Kraftaufwand erfolgen kann. Demgegenüber ist nach dem Eintritt des Kugelkopfes in die Kugelkalotte und entsprechend Rückschnappen des Gegenlagers an seinem Federsteg ein ungewolltes Herausziehen - des Kugelkopfes aufgrund der außer-axialen Lage des Federsteges ausgeschlossen, die bewirkt, daß das Gegenlager einerseits in "Normalstellung" - bezogen auf den Schwenkkreis des Gegenlagers - eine aus der radialen Mittellage ausgebogene Lage ein nimmt und bei Zug auf den Kugelkopf in diese radiale Mittellage gezogen werden müßte. Auf diese Weise wird der Kugelkopf unter der auf ihn selbst ausgeübten Zugkraft mit erhöhter Kraft in die Kugelkalotte gedrückt, so daß ein ungewolltes Herauszuiehen des Kugelkopfes aus seiner Halterung selbstverstärkend ausgeschlossen ist. Ein gewolltes Herausziehen ist demgegenüber wiederum mit geringstem Kraftaufwand möglich durch Ausbiegen des Gegenlagers ohne oder unter Zuhilfenahme eines beliebigen Werkzeuges,Due to the operative connection between the calotte on the one hand and the one attached resilient web and holding the ball head on the opposite side of the spherical counter bearing on the other hand, the counter bearing can be easily bent out to the side when inserting the ball head for the purpose of assembly, so that the assembly can be carried out with the least effort. In contrast, after the entry of the ball head into the spherical cap and corresponding snapping back of the counter bearing on its spring bar an unwanted pulling out - the ball head is excluded due to the non-axial position of the spring bar, which causes the counter bearing on the one hand in "normal position" - based on the swivel circle the counter bearing - a bent position from the radial central position and would have to be pulled into this radial central position when pulling on the ball head. In this way, the ball head is pressed with increased force into the spherical cap under the tensile force exerted on it itself, so that an unwanted pulling out of the ball head from its holder is excluded in a self-reinforcing manner. In contrast, a deliberate pulling out is again possible with the least effort by bending the counter bearing without or with the help of any tool,
In einer weiteren Λusführungsform der Erfindung Ist vorteilhaft der Verbindungsbereich zwischen Gegenlager und Federsteg derart abgekantet ist, daß auf der Einsteckseite für den Kugelkopf einen Einführungstrichter für den Kugelkopf sowie eine sich hieran anschließende Fläche in einem dem Durchmesser des Kugelkopfes entsprechenden Abstand vom Grund der Kalotte gebildet ist. Es ist auf diese Weise das Einführen des Kugelkopfes in seine Halterung ereblich vereinfacht, ohne daß hierdurch die Festigkeit und Stabilität der Verbindung beeinträchtigt wird. Die Erfindung ist in der Zeichnung anhand eines Ausführungsbeispieles erläutert. Es zeigenIn a further embodiment of the invention, the connection area between the counter bearing and the spring bar is advantageously folded such that an insertion funnel for the ball head and an adjoining surface is formed at a distance corresponding to the diameter of the ball head from the base of the spherical cap on the insertion side for the ball head . In this way, the insertion of the ball head into its holder is considerably simplified, without this affecting the strength and stability of the connection. The invention is explained in the drawing using an exemplary embodiment. Show it

Die in der Zeichnung dargestellte Kugelkopfkupplung für Bowdenzüge, besteht aus dem Endstück 2, das der Herstellung einer Verbindung zwischen dem zum Stellglied führenden Bowdenzug 1 und dem an dem Hebel 5 angeschlossenen RegelgJied dient. Hierbei wirken ein Kugelkopf 6 und eine Kugelpfanne zusammen, wobei die Kugelpfanne vυn einer Kugelkalotte 7 mit geringer, d.h. die Länge eines Kugelhalbinessers unterschreitender Höhe gebildet ist und der Kugelkopf 6 auf der der Kugelkalotte 7 abgewendeten Seite von einem Gegenlager 8 umfaßt wird, das an einem sich parallel zur Mittelebene M der Kugelkalotte erstreckenden, seitlich federnden Steg 9 gehalten ist. Hierbei ist der Federsteg 9 nach der Einsteckseite des Kugelkopfes hin aus der Mittelebene M versetzt angeordnet, während das Gegenlager 8 den Kugelkopf auf der gegenüberliegenden Seite umfaßt. Der Verbindungsbereich zwischen Gegenlager 8 und Federsteg 9 ist derart abgekantet, daß auf der Einsteckseite für den Kugelkopf 6 eine einen Einführungstrichter für den Kugelkopf bildende Fläche 10 ausgebildet ist, wobei die sich hieran anschließende, im wesentlichen ebene Fläche 11 einen dem Durchmesser des Kugelkopfes 6 entsprechenden Abstand vom Grund der Kalotte 7 aufweist ist.The ball head coupling for Bowden cables shown in the drawing consists of the end piece 2, which is used to establish a connection between the Bowden cable 1 leading to the actuator and the control member connected to the lever 5. Here, a ball head 6 and a ball socket work together, the ball socket of a spherical cap 7 having a small, i.e. the length of a hemisphere below the height is formed and the ball head 6 on the side facing away from the spherical cap 7 is surrounded by a counter bearing 8 which is held on a laterally resilient web 9 extending parallel to the central plane M of the spherical cap. Here, the spring bar 9 is arranged offset from the center plane M after the insertion side of the ball head, while the counter bearing 8 comprises the ball head on the opposite side. The connection area between the counter bearing 8 and the spring bar 9 is folded in such a way that a surface 10 forming an insertion funnel for the ball head is formed on the insertion side for the ball head 6, the adjoining, essentially flat surface 11 corresponding to the diameter of the ball head 6 Distance from the bottom of the calotte 7 is.
Zur Montage wird der Kugelkopf 6 in die Einstecköffnung eingebracht und unter Verschwenken des Gegenlagers 8 in Anlage in die Kugelkalotte 7 gebracht, worauf das Gegenlager 8 an seinem Federsteg 9 in die in Fig. 1 wiedergegebene Stellung zurückfedert, in der der Kugelkopf 6 in der Kugelkalotte 7 geklenmt gehalten ist. Für den Fall der Ausübung eines Zuges auf den Kugelkopf in der durch Pfeil P gekennzeichneten Richtung ist der Kugelkopf bestrebt, das Gegeπlager 8 mitzunehmen und zwar unter Schwenken um den den Drehpunkt D des Federsteges 9 auf dem. Kreisbogen K. Der Kreisbogen K, der die Mittelebene M im Anlagepunkt zwischen Kugelkopf 6 und Gegenlager 8 schneidet, verläuft deutlich erkennbar - gesehen in der Zugrichtung P - in die Kugel hinein, woraus erkennbar wird, daß das Gegenlager 8 den Kugelkopf 6 in einem solchen Falle mit erhöhter, der Zugkraft proportionaler Kraft in die Kugelkalotte 7 hineiudrückt. Es wird somit der Kugelkopf 6 praktisch unlösbar in dem Endstück 2 gehalten.For assembly, the ball head 6 is inserted into the insertion opening and brought into contact with the spherical cap 7 by pivoting the counter bearing 8, whereupon the counter bearing 8 springs back on its spring bar 9 into the position shown in FIG. 1, in which the ball head 6 is held clamped in the spherical cap 7. In the event of a train being exerted on the ball head in the direction indicated by arrow P, the ball head endeavors to take the thrust bearing 8 with it and to pivot it about the pivot point D of the spring bar 9 on the. Circular arc K. The circular arc K, which intersects the center plane M in the contact point between ball head 6 and counter bearing 8, runs clearly recognizable - seen in the direction of pull P - into the ball, from which it can be seen that the counter bearing 8 holds the ball head 6 in such a way Trap with increased force proportional to the tensile force is pressed into the spherical cap 7. The spherical head 6 is thus held in the end piece 2 practically insolvably.
Zum gewollten Lösen des Kugelkopfes genügt es, das Gegenlager 8 durch geringen Druck auf den Federsteg 9 in der gegen den Pfeil gerichteten Richtuug von Hand oder mittels eines Werkzeuges zu verschwenken, womit der Kugelkopf gelöst ist und ohne Kraftaufwand gezogen werden kann. Eine Materialbeanspruchung oder ein irgendwie gearteter Verschleiß sind hiermit nicht verbunden, so daß die Montage und Demontage ohne Beschädigung der Verbindung beliebig oft wiederholt werden kann. For deliberate release of the ball head, it is sufficient to pivot the counter bearing 8 by slight pressure on the spring bar 9 in the direction directed against the arrow by hand or by means of a tool, with which the ball head is released and can be pulled without effort. Material stress or any kind of wear are not associated with this, so that the assembly and disassembly can be repeated as often as required without damaging the connection.
