Description
Eine andere bekannte Kipphebelanordnung vermeidet den Z@ischenhebel. Hier werden die beiden der Nockenwelle gegenüberliegenden Ventile durch einen Gabelhebel direkt von der Stoßstange betätigt* Diese bekannte Anordnung hat aber den Nachteil, daß die beiden Stoßstangen nicht symmetrisch zur uermittelebene des Zylinderdeckels liegen.Another known rocker arm arrangement avoids the lever. Here the two valves opposite the camshaft are operated by a fork lever operated directly from the bumper * This known arrangement has the disadvantage, however, that the two bumpers are not symmetrical to the sub-center plane of the cylinder cover lie.
Die symmetrische Lage der Stoßstangen zum Zylinderdeckel hat besondere Vorteile, wenn Verbrennungskraftmaschinen mit zweiventiligenZylinderdeckeln, die fast ausnahmslos einen symmetrisch zur Zylinderquerebene liegenden Luftansaugekanal bzw.The symmetrical position of the bumpers to the cylinder cover has special features Advantages when internal combustion engines with two-valve cylinder covers that almost without exception an air intake duct lying symmetrically to the cylinder transverse plane respectively.
Gasaustrittskanal und ebenfalls symmetrisch liegende Stoßstangen aufweisen,
mit vierventiligen Zylinderdeckeln ausgerüstet werden sollen. In diesen Fällen sind
Änderungen der Nockenwelle, der Stoßstangen, der Luft-oder Abgasleitungen, der Verklei-
Der Ventilantrieb gemäß der Neuerung gestattet den Austausch eines zweiventiligen Zylinderdeckels gegen einen vierventiligen Deckel ohne Änderung der Nockenwelle, der Luft- oder Abgasleitungen, der Kraftstoffpumpenanlage, der Stoßstangen und der seitlichen Motorverkleidung. Es ändern sich lediglich der Zylinderdeckel mit seinem Kipphebelbock, die Kipphebel und die Nocken. Der Motor kann wahlweise ohne weiteren Umbau mit zwei oder vierventilifren Zylinderdeckeln ausgerüstet werden.The valve drive according to the innovation allows one to be exchanged two-valve cylinder cover against a four-valve cover without changing the Camshaft, the air or exhaust lines, the fuel pump system, the bumpers and the side engine cover. Only the cylinder cover changes with its rocker arm bracket, the rocker arms and the cams. The engine can optionally can be equipped with two or four valve cylinder covers without further modification.
Die Zeichnung zeigt eine Draufsicht auf den Zylinderdeckel mit der Kipphebelanordnung.The drawing shows a plan view of the cylinder cover with the Rocker arm assembly.
Der Zylinderdeckel l besitzt zwei Auslaßventile 2 und 3 und zwei Einlaßventile 4 und 5, die auch vertauscht sein können.The cylinder cover l has two exhaust valves 2 and 3 and two intake valves 4 and 5, which can also be interchanged.
Ihre symmetrieebene 15 ist gegen die uerebene 16 des Zylinders um
den Winkel αverdreht und schneidet die Zylinderlängsachse 7 sowie die Achse
der einen Stoßstange 13. Die Ventile 2 und 3 werden über den Gabelkipphebel 6 durch
die Stoßstange 13 und die Ventile 4 und 5 über einen Doppelkipphebel 10 und 11 durch
die stoßstange 12 betätigt. Der Gabelkipphebel 6 ist symmetrisch bezüglich der Syametrieebene
15. Um Torsionsspannungen zu vermeiden, sind beide Gabelhälften nicht gebogen, sondern
ger@de ausgeführt, so daß sich deren Mittelebene 17,
Der Doppelkipphebel besteht aus der hebelwelle 8 und den Hebelarmen 9, 10 und 11, von denen der Hebelarm 9 nicht lösbar und die beiden anderen Hebelarme 10 und 11 lösbar aber spannungsschlüssig mit der Hebelwelle 8 verbunden sind.The double rocker arm consists of the lever shaft 8 and the lever arms 9, 10 and 11, of which the lever arm 9 is not solvable and the two other lever arms 10 and 11 releasably but tension-locked with the lever shaft 8 are connected.
Die Hebelwelle 8 ist am freien Ende und zwischen den Hebelarmen 9 und 10 drehbar im Yipphebelbock 14 gelagert.The lever shaft 8 is at the free end and between the lever arms 9 and 10 rotatably mounted in the yipping lever bracket 14.
Der Kipphebelbock 14 ist mit dem Zylinderdeckel l verschraubt.
