Hintergrund der Erfindung Background of the invention
Ein solcher Hebel ist beispielsweise für den Einsatz in Motoren für Motorräder vorgesehen. Hebel, welche die Einstellung des Ventilspiels mittels einer Schraube und einer Mutter ermöglichen, sind bekannt. Die Druckschrift DE 103 41 885 A1 zeigt und beschreibt einen Ventilhebel, bei welchem die an einem Längsende des Hebels befindliche Bohrung mit einem inneren Schraubgewinde versehen ist, so dass die Einstellschraube mit ihrem äußeren Schraubgewinde dort eingeschraubt werden kann. Auf einen aus dem Hebel herausragenden oberen Endbereich wird dann eine als Sicherungsmutter bezeichnete Mutter aufgeschraubt und angezogen, bis sie in festem Kontakt mit dem Hebelkörper steht. Bei Hebeln mit mechanischer Spieleinstellung mittels Schraube und Mutter kann die Spieleinstellung durch austauschbare gestufte Elemente erfolgen. Such a lever is for example intended for use in engines for motorcycles. Levers which enable adjustment of the valve clearance by means of a screw and a nut are known. The document DE 103 41 885 A1 shows and describes a valve lever, in which the bore located at a longitudinal end of the lever is provided with an internal screw thread, so that the adjusting screw can be screwed with its outer screw thread there. On a protruding from the lever upper end portion then designated as a locknut nut is screwed and tightened until it is in firm contact with the lever body. For levers with mechanical clearance adjustment by means of screw and nut, the play adjustment can be done by interchangeable stepped elements.
Zur Erläuterung des Gebietes der Erfindung wird auch die Druckschrift DE 42 34 868 C2 erwähnt und deren Inhalt im Folgenden kurz beschrieben. Aus dieser Vorveröffentlichung ist sowohl ein Ventiltrieb mit einem Schlepphebel, als auch ein Kipphebel bekannt. Zusammenfassung der Erfindung To explain the field of the invention, the document DE 42 34 868 C2 is mentioned and their contents briefly described below. From this prior publication, both a valve train with a drag lever, as well as a rocker arm is known. Summary of the invention
Der Erfindung liegt die Aufgabe zugrunde, die Herstellung des Hebelkörpers zu vereinfachen und zu verbessern. The invention has for its object to simplify the manufacture of the lever body and to improve.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Befestigung der Einstellschraube an dem Hebel mittels einer zusätzlichen, als Kontermutter wirkenden Mutter durchgeführt ist, welche ebenfalls auf der Einstellschraube aufgeschraubt ist. Auf diese Weise kann ein Gewinde in der Bohrung des Hebelkörpers für die Einstellschraube entfallen. This object is achieved in that the attachment of the adjusting screw is carried out on the lever by means of an additional nut acting as a locknut, which is also screwed onto the adjusting screw. In this way, a thread in the bore of the lever body account for the adjusting screw.
Das Kontern der Einstellschraube erfolgt dann mittels der zusätzlichen Kontermutter, so dass die Ventilspieleinstellung trotz des Wegfalls des Gewindes im Hebelkörper weiterhin möglich ist. Durch den Wegfall des Gewindes erfolgt auch eine Steigerung der Hubzahl der Umformprozesse und eine Reduzierung der Werkzeugkosten. Außerdem kann durch den Wegfall eines Gewindedomes und der dafür nötigen Werkzeugabstandsmaße der Hebel in der Breite schmaler werden, wodurch Bauraum eingespart wird. The countering of the adjusting screw then takes place by means of the additional lock nut, so that the valve clearance adjustment is still possible despite the omission of the thread in the lever body. By eliminating the thread also increases the number of strokes of the forming processes and a reduction in tooling costs. In addition, can be narrower in width by eliminating a threaded dome and the necessary tool space dimensions, the lever, whereby space is saved.
Der Hebel kann als Kipphebel ausgeführt sein, der in seinem mittleren Bereich um eine in der Brennkraftmaschine feste Achse schwenkbar gelagert ist, wobei an seinem anderen, von der Einstellschraube abgewandten Längsende die Rolle drehbar gelagert ist. Er kann dabei als Blechkipphebel im Querschnitt umgekehrt U-förmig mit Seitenwänden ausgeführt sein. The lever may be designed as a rocker arm which is pivotally mounted in its central region about an axis fixed in the internal combustion engine, wherein at its other, remote from the adjusting screw longitudinal end of the roller is rotatably mounted. It can be designed as a sheet metal rocker in cross section inverted U-shaped with side walls.
In einer erfindungsgemäßen Ausführung des Hebels ist die Mutter auf einem aus dem Hebel herausragenden oberen Endbereich der Einstellschraube aufgeschraubt und die Kontermutter an der Unterseite des Hebels positioniert. Wenn dabei die Kontermutter viereckig (vierkantförmig) ausgeführt ist, ermöglicht diese Ausführung ein einfaches Festhalten der Kontermutter bei der Montage bzw. Ventilspieleinstellung. Mit einer solchen Kontermutter wird dann gleichzeitig der Platzbedarf im Hebelkörper reduziert. In an embodiment of the lever according to the invention, the nut is screwed onto a protruding from the lever upper end portion of the adjusting screw and the lock nut positioned on the underside of the lever. When doing this, the lock nut is square (square), this design allows for easy retention of the lock nut during assembly or valve clearance adjustment. With such a lock nut, the space required in the lever body is then reduced at the same time.
Desweiteren besteht bei dieser Ausführung hinsichtlich der minimalen Hebelbreite eine weitere Designfreiheit, da die minimale Hebelbreite nicht durch den erforderlichen Werkzeugabstand des Fertigungsschrittes„Einbringen des Gewindes" begrenzt ist. Somit kann die Forderung nach sehr schmalen Hebeln besser erfüllt werden. Furthermore, in this embodiment, in terms of the minimum lever width one further freedom of design, since the minimum lever width is not limited by the required tool spacing of the manufacturing step "inserting the thread", so that the requirement for very narrow levers can be better met.
