Ventilantrieb für BrennkraftmaschinenValve drive for internal combustion engines

Die Neuerung betrifft einen Ventilantrieb für Brennkraftmaschinen insb. mit mehreren gleichartigen, d.h. dieselbe Funktion ausübenden Ventilen pro Zylinder.The innovation concerns a valve drive for internal combustion engines in particular. with several valves of the same type, i.e. valves that perform the same function per cylinder.

Bei den bisher bekannten Ventilantrieben dieser Art sind die Kipphebel auf einer oder mehreren Achsen gelagert, die ihrerseits im Zylinderdeckel mit angegossenem Gehäuse oder in einem eigenen Kipphebelkasten mit Festsitz angeordnet sind. Um eine Beschädigung der Kipphebelbüchsen zu vermeiden, ist die Achse mehrfach im Durchmesser abgesetzt. Eine derartige Ausbildung ist jedoch teuer und erfordert eine eigene Abziehvorrichtung für den Ein- bzw. Ausbau.In the previously known valve drives of this type, the rocker arms mounted on one or more axles, which in turn are in the cylinder cover are arranged with a cast housing or in their own toggle box with a tight fit. To avoid damage to the rocker arm sleeves To avoid this, the axis is set off several times in diameter. However, such a training is expensive and requires one own puller for installation and removal.

Demgegenüber wird nach der Neuerung vorgeschlagen, die Kipphebelachse in den Zylinderdeckelseitenwänden mit Schiebesitz zu lagern und durch eine oder mehrere Zylinderdeckelschrauben in ihrer Lage mit Festsitz zu fixieren. Durch diese Maßnahme wird nicht nur die Herstellung verbilligt und die Montage vereinfacht, sondern durch die direkte Verbindung der Achse mit den Zylinderdeckelschrauben der Ventilantrieb insgesamt versteift, was insb. bei Leichtbauweise von Vorteil ist.In contrast, it is proposed according to the innovation, the rocker arm axis to be stored in the cylinder cover side walls with a sliding fit and by means of one or more cylinder cover screws in their position with a tight fit to fix. This measure not only makes the production cheaper and simplifies the assembly, but also through the direct connection of the axis with the cylinder cover screws, the valve drive is stiffened as a whole, which is particularly advantageous in the case of lightweight construction.

In der Zeichnung sind Ausführungsbeispiele der Neuerung dargestellt. Es zeigenIn the drawing, exemplary embodiments of the innovation are shown. Show it

Fig. 1 eine Draufsicht auf einen Zylinderdeckel mit der Kipphebelach.se.,Fig. 1 is a plan view of a cylinder cover with the rocker arm axle.,

Fig. 2 einen Schnitt nach Linie H-II der Fig. 1, Fig. 3 eine andere Ausführungsform.Fig. 2 is a section along line H-II of Fig. 1, 3 shows another embodiment.

Zur Betätigung der nicht gezeichneten Ventile einer Brennkraftmaschine sind im vorliegenden Fall zwei Kipphebel 1 und 2 auf einer gemeinsamen Achse 3 schwenkbar gelagert. Die Betätigung der Hebel erfolgt in bekannter Weise beispielsweise durch Stoßstangen an den Hebelenden 4 und 5. Wie insb. aus Fig. 2 ersichtlich ist,, wird der Zylinderdeckel 6 mit einem hochstehenden Rand 7 versehen., der im Bereich der Enden der Kipphebelachse 3 mit Bohrungen 8 zur Lagerung der Achsenden versehen ist. Die Fixierung der Achsen 3 erfolgt durch die Zylinderdeckelschrauben 9, welche in der Nähe der Enden mit einem Teil ihres Querschnitts in senkrecht zur Achse am Umfang derselben verlaufende Aussparungen 10 greifen.For actuating the valves, not shown, of an internal combustion engine In the present case, two rocker arms 1 and 2 are pivotably mounted on a common axis 3. The lever is operated in a known manner Way, for example, by bumpers at the lever ends 4 and 5. As can be seen in particular from Fig. 2, the cylinder cover 6 is with a upstanding edge 7 provided., in the region of the ends of the Rocker arm axis 3 is provided with holes 8 for mounting the axis ends. The axes 3 are fixed using the cylinder cover screws 9, which near the ends with part of their cross-section in recesses running perpendicular to the axis on the circumference of the same 10 grab.

Bei der Ausführung nach Fig. 3 sind die Zylinderdeckelschrauben 9 die Enden der Kipphebelachsen 3 diametral durchdringend angeordnet.In the embodiment according to FIG. 3, the cylinder cover screws 9 are arranged to penetrate the ends of the rocker arm axes 3 diametrically.
