Description

  

  Luftgekühlter     Notor.       Die Zylinder luftgekühlter Motoren wer  den meistens einzeln und mit getrennten  Zylinderköpfen ausgeführt. Die Motoren wer  den dabei gewöhnlich so zusammengebaut,  dass man zuerst die Zylinder mittels Flansch  am Kurbelgehäuse befestigt, auf die Zylinder  dann die Köpfe und auf diese das Nocken  wellengehäuse aufsetzt. Diese Anordnung  hat den Nachteil, dass die     Passflächen    der  Zylinderköpfe auch bei der besten Ausfüh  rung nicht genau in einer Ebene liegen, wes  halb sich die Nockenwelle häufig durchbiegt  und in den,     Lagern    klemmt.  



  Beim Motor gemäss der Erfindung ist die  ser Mangel dadurch beseitigt, dass die Zylin  der mit den Zylinderköpfen am     Gehäuse    der  Nockenwelle befestigt sind und dass     dieses     Gehäuse seinerseits, zum Beispiel mittels Bol  zen, an dem Kurbelgehäuse befestigt ist,       wobei    die     untern    Teile der Zylinder unter  Zwischenlage von Dichtungen gegenüber dem  Kurbelgehäuse verschiebbar sind.    Die Zeichnung zeigt     schematisch        ein.     Ausführungsbeispiel des Erfindungsgegen  standes, wobei nur ein Zylinder dargestellt  ist.  



  Das     Gehäuse    1 der Nockenwelle 2 ist mit  tels der Bolzen 3     am.        Kurbelgehäuse    4 be  festigt. Der mittels der Schrauben 6 mit dem  Zylinder 7     verbundene    Zylinderkopf 5 ist  von unten am     Nockenwellengehäuse    1 eben  falls mittels der     Bolzen    3 befestigt.  



  Zwischen dem Kurbelgehäuse 4 und dem  Zylinder 7 ist eine     Dichtung    8 vorgesehen, so  dass der untere Teil des Zylinders 7 gegen  über dem Kurbelgehäuse 4 verschiebbar ist.  Es ist somit eine freie Wärmeausdehnung des  Zylinders 7 möglich. Bei einer solchen An  ordnung ist eine gute Lagerung der Nocken  welle gesichert und auch die Möglichkeit der  verschiedenartigen Ausdehnung der     einzelnen     Zylinder ohne Ausübung eines ungünstigen  Einflusses auf das Nocken- und Kurbelge  häuse gegeben.



  Air-cooled notor. The cylinders of air-cooled engines are usually designed individually and with separate cylinder heads. The engines are usually assembled in such a way that the cylinders are first attached to the crankcase by means of a flange, then the heads are placed on the cylinders and the camshaft housing is placed on them. This arrangement has the disadvantage that the mating surfaces of the cylinder heads are not exactly in one plane, even with the best execution, which means that the camshaft often bends and jams in the bearings.



  In the engine according to the invention this deficiency is eliminated in that the cylinder with the cylinder heads are attached to the housing of the camshaft and that this housing in turn, for example by means of Bol zen, is attached to the crankcase, with the lower parts of the cylinder below Intermediate layer of seals relative to the crankcase are displaceable. The drawing shows schematically a. Embodiment of the subject matter of the invention, only one cylinder is shown.



  The housing 1 of the camshaft 2 is fastened by means of the bolts 3 to the crankcase 4. The cylinder head 5, which is connected to the cylinder 7 by means of the screws 6, is also attached to the camshaft housing 1 from below by means of the bolts 3.



  A seal 8 is provided between the crankcase 4 and the cylinder 7, so that the lower part of the cylinder 7 can be displaced relative to the crankcase 4. Free thermal expansion of the cylinder 7 is thus possible. In such an arrangement, good storage of the cam shaft is ensured and the possibility of various expansion of the individual cylinders without exerting an unfavorable influence on the cam and crank housing is given.
