Halteklammer mit Verbindungselement für einseitig gelagerte HebelRetaining clip with connecting element for levers mounted on one side

Die Erfindung betrifft eine Halteklammer mit Verbindungselement für einseitig gelagerteHebel insbesondere für sogenannte Schlepphebel zur Ventilbetätigung in Verbrennungsmotoren als Fixierung auf den Lagerbolzen (Kugelbolzen),The invention relates to a retaining clip with a connecting element for levers mounted on one side, in particular for so-called Rocker arm for valve actuation in combustion engines as a fixation on the bearing pin (ball pin),

Für die zur Erzielung der notwendigen Freiheitsgrade meist auf Kugeln oder Schneiden gelagerten Hebel ist eine Fixierung auf der Kugel oder der Schneide erforderlich. Diese Fixierung soll einerseits den Hebel sicher auf der Kugel oder der Schneide halten, andrerseits soll einem Ausweichen des Hebels nach den erwünschten Bewegungsrichtungen durch die Halteklammer nicht verhindert werden. Außerdem soll eine leichte Montage und Demontage gewährleistet sein.For the levers, which are usually mounted on balls or cutting edges to achieve the necessary degrees of freedom, a fixation is required the ball or the cutting edge is required. This fixation should, on the one hand, keep the lever securely on the ball or the cutting edge hold, on the other hand, the lever should not give way to the desired directions of movement through the retaining clip be prevented. In addition, easy assembly and disassembly should be guaranteed.

Ss ist bekannt zur Erfüllung dieser Aufgabe Federn aus Flachmaterial gemäß Figur 1 oder Federn aus Runddraht gemäß Figur 2 einzusetzen. Auch Federn gemäß 3 und 3a werden verwendet.Ss is known to fulfill this task springs made of flat material according to FIG. 1 or springs made of round wire according to FIG. Springs according to FIGS. 3 and 3a are also used.

Die Ausführung nach Figur 1 hat den Nachteil geringer Materialausnutzung. Die Ausführung gemäß Figur 2 erfordert mehr Herstellungsaufwand und ist schwieriger zu montieren. Die Ausführung nach Figur 3 und 3a gewährleistet keine sichere Fixierung des Hebels auf Kugel oder Schneide.The embodiment according to FIG. 1 has the disadvantage of low material utilization. The embodiment according to FIG. 2 requires more manufacturing effort and is more difficult to assemble. Execution according to Figure 3 and 3a does not ensure a secure fixation of the lever on the ball or cutting edge.

Der Erfindung liegt die Aufgabe zugrunde, die Vorteile der einzelnen Ausführungen 1,2,3 und 3a durch entsprechende Formgebung und Materialauswahl zu nutzen ohne deren Nachteile zu übernehmen.The invention is based on the object of the advantages of to use individual designs 1, 2, 3 and 3a by appropriate shaping and material selection without their disadvantages take over.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine aus Federstahldraht geformte Halteklammer mit einem Verbindungsele-This object is achieved according to the invention in that a retaining clip formed from spring steel wire with a connecting element

ment 30 kombiniert wird, daß die freien Schenkel in ihrem Federweg soweit eingeschränkt werden, daß zwar eine Montage (zum Beispiel Aufschieben auf einen Bolzen) noch möglich, eine selbständige Lösung aus der Montagelage durch notwendige Bewegungsvorgänge im Betrieb des Hebels aber nicht möglich ist. ment 30 is combined that the free legs in their travel be restricted to the extent that an assembly (e.g. sliding onto a bolt) is still possible, an independent one Solution from the assembly position through necessary movements during operation of the lever is not possible.

Um eine leichtere Montage der Halteklammer zu erleichtern, kann das erforderliche Verbindungselement unlösbar mit der Halteklammer verbunden sein.In order to facilitate easier assembly of the retaining clip, the required connecting element can be inextricably linked to the retaining clip be connected.

Die mit der Erfindung erzielten Vorteile liegen darin, daß einerseits die Montage erleichtert wird und trotzdem eine günstige Materialausnutzung bei gleichzeitiger sicherer Fixierung des Hebels auf der Lagerkugel oder der Lagerschneide gewährleistet ist.The advantages achieved by the invention are that on the one hand the assembly is facilitated and still a favorable material utilization while at the same time securely fixing the lever on the bearing ball or the bearing edge is guaranteed is.

Ein Ausführungsbeispiel der Erfindung ist in der Figur 4 und eine Variante in Figur 4a dargestellt. Die Halteklammer in Figur 4 besteht aus einer Biegefeder A und einem Verbindeelement B. Während durch den geschlossenen Bügel 1 die Kraft für die Fixierung des Hebels auf dem Lagerpunkt übertragen wird, gibt das Verbindungselement B den freien Schenkeln 2 und 3 die nötige Abstützung für einen sicheren Halt in der vorgesehenen Haltenut.An exemplary embodiment of the invention is shown in FIG. 4 and a variant in FIG. 4a. The retaining clip in Figure 4 consists of a spiral spring A and a connecting element B. While the closed bracket 1, the force is transferred for the fixation of the lever on the bearing point, the connecting element B gives the free legs 2 and 3 the necessary support for a secure hold in the intended Holding groove.
