Hintergrund der Erfindungbackground the invention
Als gattungsbildend werden Kipphebel aus Stahlblech angesehen, die im Querschnitt generell U-förmig und bezogen auf ihre Längsmittelebene im wesentlichen symmetrisch ausgebildet sind. Sollen derartige Nockenfolger bspw. in Ventiltriebe von niedrighubigen Motoren für Zweiräder bzw. für Kleingeräte ein gebaut werden, kann es zu Einbauproblemen kommen. Den notwendigen Verschwenkwinkel des Hebels können einragende Bauteile unnötig einschränken.When Generic rocker arms made of sheet steel are considered in the Cross section generally U-shaped and based on their median longitudinal plane are formed substantially symmetrical. Should such cam follower For example, in valve trains of low-order engines for two-wheelers or built for small appliances become, it can come to installation problems. The necessary pivot angle of the lever can protruding components unnecessary limit.
Außerdem genügen die Kipphebel nach dem Stand der Technik sehr oft nicht den Anforderungen hinsichtlich Leichtbau und niedriger Herstellkosten.In addition, the suffice Rocker arm according to the prior art very often does not meet the requirements Lightweight construction and low production costs.
Aufgabe der ErfindungTask of invention
Aufgabe der Erfindung ist es daher, einen Kipphebel der vorgenannten Art zu schaffen, bei dem die zitierten Nachteile beseitigt sind. Insbesondere soll ein derartiger Kipphebel in beengte Bauräume integrierbar sein und hinsichtlich Leichtbau und Kosten optimiert vorliegen.task The invention is therefore a rocker arm of the aforementioned type in which the cited disadvantages are eliminated. In particular, should Such a rocker arm can be integrated in tight spaces and in terms Lightweight construction and costs are optimized.
Lösung der AufgabeSolution of task
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass der Kipphebel wenigstens an dem einen Ende vom Querbalken ausgespart ist, wobei die Seitenwände in diesem Bereich zueinander im wesentlichen parallel sind und zwei miteinander fluchtende Bohrungen haben, in denen ein Bolzen mit einer Nockenanlaufrolle als Abgriffsfläche aufgenommen oder aufnehmbar ist und wobei den Seitenwänden, zumindest in Ihrem Mittelteil mit den Öffnungen, ein zueinander unsymmetrischer Verlauf immanent ist.According to the invention this Task solved by that the rocker arm recessed at least at one end of the crossbar is, with the side walls in this area are substantially parallel to each other and two have aligned holes, in which a bolt with a Nockenanlaufrolle recorded as a tap area or receivable is and where the side walls, at least in your middle part with the openings, one to each other more asymmetrical Course is immanent.
Somit liegt ein Kipphebel vor, bei dem die eingangs zitierten Nachteile wirkungsvoll beseitigt sind. Der erfindungsgemäße Kipphebel ist ggf. auch da einsetzbar, wo ein symmetrischer Hebel in Kontakt mit Zylinderkopf- bzw. Brennkraftmaschinenbauteilen käme. Dessen Seitenwände weichen somit quasi den vorgenannten Bauteilen aus. Außerdem ist klar, dass zumindest an dem einen Ende durch die in ihrem Abstand minimierten Seitenwände und die gleichzeitig vorliegende Aussparung des Querbalkens die oszillierenden Ventiltriebsmassen gesenkt sind.Consequently is a rocker arm, in which the cited disadvantages are effectively eliminated. The rocker arm according to the invention is possibly there as well can be used where a symmetrical lever in contact with cylinder head or internal combustion engine components would come. Its sidewalls give way thus virtually the aforementioned components. It is also clear that at least at one end by the minimized in their distance side walls and the simultaneously existing recess of the crossbeam the oscillating Valve drive masses are lowered.
Die erfindungsgemäße „Kröpfung" der Seitenwände kann in einer oder mehreren Ziehstufen dargestellt werden. In Draufsicht wird somit über die „Kröpfung" ein Z- oder S-ähnliches Profil an zumindest einer Seitenwand geschaffen, dem die andere Seitenwand wahlweise folgen kann. Jedoch ist es denkbar und vorgesehen, die „Kröpfung" nicht derart stark wie bei der erstgenannten Seitenwand auszuführen.The According to the invention, "curvature" of the side walls in one or more draw levels. In plan view is thus over the "crank" a Z- or S-like Profile created on at least one side wall, the other side wall Optionally follow. However, it is conceivable and intended, the "crank" not so strong as in the first-mentioned side wall.
Im Bereich des erfindungsgemäß gabelartig ausgebildeten einen ausgesparten Endes des Kipphebels kann zweckmäßigerweise eine auf einem Bolzen gelagerte, drehbare Rolle appliziert werden. Wahlweise kann die Rolle über geeignete Wälzkörper wie Nadeln auf dem Bolzen verlaufen. Gegebenenfalls ist in diesem Bereich jedoch auch ein Gleitabgriff denkbar. Ggf. kann die Erfindung auch ohne das gabelartige ausgesparte Ende ausgeführt werdenin the Area of the present invention fork-like a recessed end of the rocker arm may conveniently a mounted on a bolt, rotatable roller can be applied. Optional can the role over suitable rolling elements such Needles run on the bolt. Where appropriate, this is in this area However, a Gleitabgriff conceivable. Possibly. the invention can also be performed without the forked recessed end
In Fortbildung der Erfindung ist es vorgesehen, dass am anderen Ende des Hebels, einteilig aus dessen Querbalken heraus sowie in ventilferne Richtung, ein hohlzylindrischer Ansatz geformt ist. Dieser kann beispielsweise noch vor einem Biegevorgang der Seitenwände gebildet werden. Er dient zweckmäßigerweise der Anordnung einer Schraubverbindung zur Einstellung des Ventilspiels. Gegebenenfalls kann sich der Ansatz auch in Ventilrichtung erstrecken.In Training the invention, it is provided that at the other end of the lever, in one piece from the transom and in ventilferne Direction, a hollow cylindrical approach is formed. This one can for example, formed before a bending operation of the side walls become. He serves appropriately the arrangement of a screw connection for adjusting the valve clearance. Optionally, the approach may also extend in the valve direction.
Insbesondere ist es vorgesehen, die Seitenwände an ihrer Unterseite durch den Querbalken verbinden zu lassen, so dass ein U-ähnliches Profil geschaffen ist. Denkbar und vorgesehen ist es jedoch auch, ein umgekehrt U-ähnliches Profil bzw. ein H-ähnliches Profil zu generieren.Especially it is intended the side walls at the bottom to be connected by the transom, so that a U-like Profile is created. However, it is also conceivable and planned an inverted U-like Profile or H-like Generate profile.
In Konkretisierung der Erfindung ist es vorgesehen, die Öffnungen in den Seitenwänden als einteilig aus diesen heraus geformte Lageraugen darzustellen. Beispielsweise können diese Lageraugen die Seitenwände nach außen überragen. Denkbar und vorgesehen ist es jedoch auch, dass die Lageraugen nach innen angeformt sind. Aufgrund deren einteiliger Ausbildung sind die Fertigungskosten nicht unnötig erhöht. Im Bereich der Lageraugen können auch Wälzlager eingesetzt werden, über welche der Kipphebel dann unmittelbar auf seiner Achse äußerst reibungsarm verläuft.In concretization of the invention, it is provided to represent the openings in the side walls as integrally formed out of these bearing eyes. For example, these bearing eyes can project beyond the side walls to the outside. However, it is conceivable and intended that the bearing eyes are molded inwards. Due to their one-piece design, the manufacturing costs are not unnecessary tig increased. Rolling bearings can also be used in the area of the bearing eyes, over which the tilting lever then runs with extremely low friction directly on its axis.
Alternativ zu der vorgenannten Ausgestaltung ist es vorgesehen, die Öffnungen in den Seitenwänden, die vorzugsweise bei beiden Varianten in einem Mittenbereich des Kipphebels angeordnet sind, durch ein in diesen befestigtes Rohrstück zu verbinden. Über dieses Rohrstück verläuft der Kipphebel auf einer Achse oder dergleichen. Zur weiteren Verschleißreduzierung kann auch in diesem Bereich eine Wälzlagerung appliziert werden.alternative to the aforementioned embodiment, it is provided, the openings in the side walls, which preferably in both variants in a central region of the Rocker arms are arranged to connect by a piece of pipe fixed in this. About this pipe section extends the rocker arm on an axle or the like. For further wear reduction can be applied in this area a rolling bearing.
Die erfindungsgemäßen Maßnahmen können vom Grunde her auch bei einem Schlepp- oder Schwinghebel ausgeführt werden.The inventive measures can basically also be carried out with a towing or rocking lever.
