Description
Ventilfederanordnung für Brennkraftmaschinen Die Erfindung bezieht sich auf eine Ventilfederanordnung für Brennkraftmaschinen. Es sind hier bereits Anordnungen bekannt, bei denen ein das Ventil steuernder Schwinghebel eine Schulter trägt, gegen die sich das eine Ende der Ventilfeder abstützt.Valve spring assembly for internal combustion engines The invention relates on a valve spring assembly for internal combustion engines. There are already here Arrangements are known in which a rocker arm controlling the valve has a shoulder carries against which one end of the valve spring is supported.
Für die Betriebssicherheit derartiger Ventilfederanordnungen ist es von großer Bedeutung, daß sich die Ventilfeder während der Ventilbewegung möglichst in Ruhe befindet. Eine soweit wie möglich gehende Erfüllung dieser Bedingung ist erforderlich, wenn man Resonanzwirkungen vermeiden will.For the operational safety of such valve spring arrangements it is It is very important that the valve spring is as close as possible during the valve movement is at rest. A fulfillment of this condition as far as possible is necessary if you want to avoid resonance effects.
Gemäß der Erfindung wird eine praktisch vollständige Unterdrückung der störenden Federschwingungen dadurch erreicht, daß das eine Ende der über dem Schwinghebel liegenden Ventilfeder, deren anderes Ende, wie bereits erwähnt, sich gegen eine Schulter des Schwinghebels abstützt, auf einem Federteller ruht, der sich seinerseits an einem in dem Steuerungsgehäuse verstellbaren Schraubenbolzen mittels Kugelzapfen abstützt.According to the invention there is practically complete suppression the disruptive spring vibrations achieved in that one end of the above Rocker arm lying valve spring, the other end of which, as already mentioned, is supported against a shoulder of the rocker arm, rests on a spring plate that in turn on an adjustable screw bolt in the control housing supported by ball studs.
In der Zeichnung ist ein AusführungAeispiel der Erfindung dargestellt.In the drawing, an embodiment of the invention is shown.
Fig. i zeigt einen Schnitt durch einen Zylinderkopf, der eine Ventilfederanor dnung gemäß der Erfindung enthält.Fig. I shows a section through a cylinder head, which a Ventilfederanor contains elongation according to the invention.
Fig. 2 zeigt eine Draufsicht auf die Feder; die Deckelplatte ist hierbei entfernt.Fig. 2 shows a plan view of the spring; the cover plate is here removed.
Das in dem Zylinderkopf 2 gelagerte Ventil i wird durch einen Hebel 3 gesteuert, der um den Zapfen 4 schwingt. Die Steuerung des Schwinghebels 3 erfolgt über eine Stange 5 von der Nockenwelle des Motors aus. Der Schwinghebel 3 trägt eine Schulter 6 mit einer halbkugelförmigen Stützfläche. Diese dient zur Aufnahme des kugeligen Kopfes 7 eines Federtellers 8, gegen den sich die Ventilfeder 9 mit einem Ende abstützt; mit ihrem anderen Ende stützt sich die Feder 9 auf einem zweiten Federteller io ab, in dessen halbkugelförmiges Stützlager ein Kugelzapfen i i eingreift. Dieser bildet -in Stück mit einem Schraubenbolzen 12, der in das obere Gehäuse 13 einsgeschraubt ist. Mittels dieses Schraubenbolzens 12 kann man die Federspannung regeln. Das Gehäuse ist durch einen Deckel 14 abgedeckt. Auf das äußere Ende der Schraube 12 ist eine Gegenmutter 15 zur Sicherung aufgeschraubt.The valve i mounted in the cylinder head 2 is controlled by a lever 3 controlled, which swings around the pin 4. The control of the rocker arm 3 takes place via a rod 5 from the camshaft of the engine. The rocker arm 3 carries a shoulder 6 with a hemispherical support surface. This is used for recording of the spherical head 7 of a spring plate 8, against which the valve spring 9 with supports one end; at its other end, the spring 9 is supported on a second Spring plate io, in whose hemispherical support bearing a ball pin i i engages. This forms - in one piece with a screw bolt 12, which is inserted into the upper housing 13 is screwed in. By means of this screw bolt 12 you can adjust the spring tension rules. The housing is covered by a cover 14. On the outer end of the Screw 12, a lock nut 15 is screwed on for securing.
Die Länge der Arme des Hebels 3, gerechnet von der Dehachse .4 aus, wird derart gewählt, daß der Hebel eine Untersetzung zwischen der Feder und dem Ventil bildet, um die Schwingungsweite der Feder zu verringern. Die Feder ist weiterhin, infolge der Art ihrer Anordnung ziemlich weit von dem Zylinderkopf entfernt, so daß sie im geringeren Maße, als sonst üblich, erwärmt wird.The length of the arms of the lever 3, calculated from the axis of rotation .4, is chosen so that the lever is a reduction between the spring and the Valve forms in order to reduce the oscillation amplitude of the spring. The pen is still quite far from the cylinder head due to the nature of their arrangement, so that it is heated to a lesser extent than usual.
