Abstract
Description
Kombinierte -Dreh- und Verschiebesicheruno für einen Bolzen Combined rotation and displacement security for one bolt
Die Erfindung betrifft eine kombinierte Dreh- und Verschiebesicherung gemäß dem Gattungsbegriff des Patentanspruchs 1.The invention relates to a combined rotation and displacement lock according to the generic term of claim 1.
Der bevorzugte Anwendungsfall der Erfindung ist die Sicherung des Lagerbolzens eines Handbremshebels in einem Kraftfahrzeug gegen Dreh- und Verschiebebewegungen. Wie sich nämlich gezeigt hat, kann bei der üblichen Bolzenlagerung, bei der der Bolzen durch zwei Sicherungsringe lediglich gegen seitliches Herausrutschen aus einem Lagerbock geschützt ist, bei häufiger Bedienung des Handbremshebels sich dieser auf dem Bolzen festklemmen und den Bolzen bei jeder Hebelbetätigung im Lagerbock drehen. Dadurch werden die Aufnahmelöcher des Lagerbocks für den Bolzen einseitig ausgearbeitet, so daß es zu einem unzulässig großen Lagerspiel kommen kann.The preferred application of the invention is to secure the Bearing bolt of a handbrake lever in a motor vehicle against rotating and sliding movements. As has been shown, can with the usual bolt storage, in which the Bolts by two retaining rings only to prevent them from slipping out to the side a bearing block is protected, with frequent use of the handbrake lever this Clamp on the bolt and the bolt in the bearing block each time the lever is operated turn. As a result, the mounting holes in the bearing block for the bolt become one-sided worked out so that there may be an inadmissibly large bearing play.
Der Erfindung liegt ganz allgemein die Aufgabe zugrunde, eine kombinierte Dreh- und Verschiebesicherung für einen Bolzen gemäß dem Gattungsbegriff des Patentanspruchs 1 zu schaffen, die einstückig ausgebildet ist und eine einfache Montage sowie Demontage gestattet. Das bedeutet, daß irgendwelche Dauerverbindungen, beispielsweise Schweißverbindungen, vermieden sein sollen.The invention is very generally based on the object of a combined Rotation and displacement protection for a bolt according to the generic term of the patent claim 1, which is formed in one piece and easy assembly and disassembly allowed. This means that any permanent connections, for example welded connections, should be avoided.
Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kennzeichnenden Merkmalen des Patentanspruchs 1.The inventive solution to this problem consists in the characterizing Features of claim 1.
Ein wesentlicher Vorteil der Erfindung ist darin zu sehen, daß das einzige zusätzliche Teil der Sicherung, nämlich das Federblech, nicht nur den Bolzen sowohl gegen Drehbewegungen-als auch gegen axiale Bewegungen sichert, sondern auch eine Sicherung gegen eigenes Abrutschen von dem das Lager für den Bolzen bildenden Schenkel beinhaltet.A major advantage of the invention is the fact that the only additional part of the fuse, namely the spring plate, not just the bolt secures against both rotational movements and against axial movements, but also a safeguard against slipping from the one forming the bearing for the bolt Includes thigh.
Betrachtet man demgegenüber den Stand der Technik, gegeben durch die DE-OS 24 60 100, so findet sich dort zwar ein Federblech, das über ein von einem gegen Drehungen zu sichernden Teil, insbesondere einer Schraube, durchsetztes Blech mit einem U-förmigen Bereich geschoben ist, aber es handelt sich um eine reine Drehsicherung. Die bekannte Sicherung ist ohne Abänderung nicht in der Lage, das gegen Drehungen zu sichernde Teil auch gegen axiale Bewegungen zu sichern, und die das gegen Drehungen zu sichernde Teil zwischen sich einschließenden Schenkel des Federblechs müssen zugleich die zur Sicherung gegen Abrutschen desselben erforderliche Kraft aufbringen.In contrast, if you consider the state of the art, given by the DE-OS 24 60 100, there is indeed a spring plate, which has one of a Part to be secured against rotation, in particular a screw, penetrated sheet metal is pushed with a U-shaped area, but it is purely a rotation lock. The known safety device is not able to prevent rotation without modification The part to be secured must also be secured against axial movements, and that against rotation the part to be secured between the enclosing legs of the spring plate at the same time apply the same force required to secure it against slipping.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous refinements of the invention are the subject matter of the subclaims.
Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand der Zeichnung erläutert, deren Figur 1 perspektivisch eine mit der erfindungsgemäßen Sicherung ausgerüstete Lagerung für den Handbremshebel eines Kraftfahrzeugs zeigt, während Figur 2 eine Seitenansicht des Bolzens wiedergibt.An embodiment of the invention is described below with reference to the Drawing explained, the figure 1 in perspective one with the inventive Shows securing equipped storage for the handbrake lever of a motor vehicle, while Figure 2 shows a side view of the bolt.
Der Handbremshebel ist allgemein mit 1, sein Lagerbock allgemein mit 2 bezeichnet. Der Lagerbock 2 besitzt die beiden parallelen Schenkel 3 und 4, die mit fluchtenden Durchtrittslöchern für den die Lagerachse des Hebels 1 darstellenden hohlen Bolzen 5 versehen sind. Wie insbesondere aus Figur 2 ersichtlich, besitzt der Bolzen 5 zwei in diesem Ausführungsbeispiel parallele Einstiche 6 und 7, in die einander zugekehrte Kanten der beiden Schenkel 8 und 9 des Federblechs 10 eingreifen. Damit ist der Bolzen 5 gegen Drehbewegungen relativ zum Federblech 10 gesichert, das seinerseits drehfest am Schenkel 3 des Lagerbocks 2 befestigt ist. Hierzu dient primär der die Kante 11 des Schenkels 3 U-förmig übergreifende Bereich 12 des Federblechs 10, in diesem Ausführungsbeispiel in Verbindung mit der sich ebenfalls auf die Kante auflegenden bzw. diese übergreifenden Abbiegung 13 des Federblechs 10. Wie Figur 1 zeigt, beschreibt in diesem Ausführungsbeispiel im Bereich des Bolzens 5 die Kante 11 einen konvexen Kreisbogen, und die Abbiegung 13 sowie die auf der Kante 11 aufliegende Basis des U-förmigen Bereichs 12 schließen miteinander einen Winkel von etwa 900 ein.The handbrake lever is generally indicated by 1, its bearing bracket generally indicated by 2 designated. The bracket 2 has the two parallel legs 3 and 4, the with aligned through holes for the bearing axis of the lever 1 representing hollow bolts 5 are provided. As can be seen in particular from Figure 2, has the bolt 5 has two recesses 6 and 7, which are parallel in this exemplary embodiment, in the mutually facing edges of the two legs 8 and 9 of the spring plate 10 engage. So that the bolt 5 is against Rotational movements relative to the spring plate 10 secured, which in turn is non-rotatably attached to the leg 3 of the bearing block 2 is. For this purpose, the edge 11 of the leg 3 overlapping in a U-shape is primarily used Area 12 of the spring plate 10, in this embodiment in connection with the also resting on the edge or this overlapping bend 13 of the spring plate 10. As Figure 1 shows, describes in this embodiment in the area of the bolt 5, the edge 11 has a convex circular arc, and the bend 13 and the base of the U-shaped area 12 resting on the edge 11 each other at an angle of about 900.
Zur Sicherung gegen Abrutschen ist im Federblech 10 die in Richtung auf den Schenkel 3 weisende Ausdrückung 14 vorgesehen, die zusammen mit dem Rand der ein Gegenprofil darstellenden Vertiefung 15 im Schenkel 3 eine Schnapparretierung für das Federblech 10 bildet. Die beiden Bestandteile 14 und 15 dieser Schnapparretierung liegen in dem gezeigten Ausführungsbeispiel auf Kreisbögen um die Achse des Bolzens 9.To secure against slipping is in the spring plate 10 in the direction on the leg 3 facing expression 14 is provided, which together with the edge the recess 15 in the leg 3, which represents a counter profile, has a snap lock for the spring plate 10 forms. The two components 14 and 15 of this snap lock lie in the embodiment shown on arcs around the axis of the bolt 9.
Infolge des Eingriffs des Federblechs 10 -in die Einstiche 6 und 7 des Bolzens 5 ist eine zusätzliche Bewegungssicherung für den Bolzen 5 an dem anderen Schenkel 4 des Lagerbocks 2 überflüssig.As a result of the engagement of the spring plate 10 in the recesses 6 and 7 of the bolt 5 is an additional movement lock for the bolt 5 on the other Leg 4 of the bearing block 2 superfluous.
