Description

Nockenwelle mehrzylindriger Verbrennungsmotoren. Nockenwellen, deren Nocken in das Fleisch eines runden Stabes eingefräst sind, und deren zylindrische Teile gleichzeitig als Lagerzapfen in einer rohrförmigen Lagerbüchse laufen, sind bei Dampfmaschinen verwendet worden, und zwar zu dem Zwecke, die Abdichtung der Ventilgehäuse und die Herstellung solcher Wellen zu vereinfachen.Camshaft of multi-cylinder internal combustion engines. Camshafts whose Cams are milled into the flesh of a round rod, and their cylindrical Parts run at the same time as bearing journals in a tubular bearing bush has been used in steam engines for the purpose of sealing the To simplify valve housing and the manufacture of such shafts.

Der vorliegenden Erfindung gemäß wird diese an sich bekannte Konstruktion und Lagerung von Nockenwellen auf mehrzylindrige Fahrzeugverbrennungsmotoren zu dem Zwecke übertragen, um einen möglichst ruhigen und geräuschlosen Gang zu erzielen, welcher, wie bekannt, nur dadurch erreicht wird, daß Schwingungen und Durchbiegungen der Welle vermieden und die Umfangsgeschwindigkeiten der Nockenflächen möglichst klein gehalten werden. Diese beiden Anforderungen sind bei Verbrennungskraftmaschinen von weit größerer Bedeutung als bei Dampfmaschinen, weil die Tourenzahl ersterer größer ist.According to the present invention, this construction is known per se and bearing camshafts for multi-cylinder vehicle internal combustion engines transferred to the purpose of achieving the quietest and most noiseless gait possible, which, as is known, is only achieved by vibrations and deflections the shaft avoided and the circumferential speeds of the cam surfaces as possible can be kept small. These two requirements apply to internal combustion engines of far greater importance than with steam engines, because the number of revolutions is the former is bigger.

Die Zeichnung zeigt e,in Ausführungsbeispiel für einen vierzylindrigen 1lo;or, und zwar in Fig. i im Längsschnitt und in . I@i g. _ im Querschnitt.The drawing shows e, in an exemplary embodiment for a four-cylinder 1lo; or, namely in Fig. I in longitudinal section and in. I @ i g. _ in cross section.

Die Nockenwelle wird in der Weise hergestellt, daß die einzelnen i\Tocken i in das Fleisch eines runden Stabes eingefräst werden. Die zylindrischen Teile 2 dienen als Lagerzapfen, die in der rohrförmigen Lagerbüchse 3 laufen. Diese letztere ist in entsprechender «"eise im llotorgehäuse.f befestigt und mit Bohrungen versehen, durch welche die Ventilstößel 5 an die INTocken reichen.The camshaft is manufactured in such a way that the individual i \ Tocken i can be milled into the flesh of a round stick. The cylindrical parts 2 serve as bearing journals that run in the tubular bearing bush 3. This latter is fixed in the appropriate "" iron in the motor housing.f and provided with holes, through which the valve tappets 5 reach the INTock.

Jede N ocke ist also an beiden Seiten gelagert und die Nockenwelle ist gegen Durchbi c-gungen und Schwingungen vollkommen geschützt.Each cam is therefore supported on both sides, as is the camshaft is completely protected against sagging and vibrations.

Die einzelnen -zylindrischen Lagerzapfen sind untereinander durch das ganze Profil der Nocken verbunden und kann infolgedessen als auch infolge der reichlichen Lagerung der Grundkreis der Nocken sehr klein gewählt «-erden.The individual cylindrical bearing journals are through each other the whole profile of the cam connected and can as a result as well as as a result of the ample storage, the base circle of the cams is chosen to be very small.
