Description
Luftgekühlte, aufgeladene Brennkraftmaschine. Die Erfindung bezieht sich auf eine duft gekühlte, aufgeladene B:rennkraftmäschine, bei .der die Kühlung durch ein Achsialgebläse, die Auf ladung -durch einRaditlgebläse bewizkt wird, und besteht darin, dass die Gebläserä- der beider Gebläse auf einer gemeinsamen Welle befestigt sind,
wobei das Küh!lluftge- bläse die Ansaugeluft für das Aufladegebläse liefert.
In der Zeichnung ist ein Ausführungsbei spiel des Erfindungsgegenstandes dargestellt, und zwar zeigt: Fig. 1 einen stehenden Reihenmotor mit den Gebläsen im Grundriss, im Schnitt, Fig. 92 den Querschnitt durch die Ma schine nach Linie II-II der Fig. 1.
Die 14lotc-rzylindler 1 sind senkrecht und in Reihe angeordnet. Die Gebläse werden von ,der Schwungradeeite des Motors aus angetrie ben, wo die Geschwindigkeitsschwankungen am kleinsten sind, und, zwar über ein auf dem .Schwungrad 2 sitzendes Zahnrad ä, ein Zwischenrad 17 und ein Ritzel 4, das auf der :
längs des Motors neben den Zylindern verlaufenden Welle 5 festsitzt, .die als Tor sionsfederstab ausgebildet sein kann. Auf die ser Welle 5 ist das Kühlgebläserad 6 be festigt, wobei das Ende der Welle 5 in dem mit dem Ansaugtrichter 7 fest verbundenen Lager 8 gelagert ist. Das Ladegebläserad 9 ist lose auf der Welle 5 gelagert und mit dem gühlgebläserad durch die Hohlwelle 10 fest verbunden.
Das Kühlgebläse 6 saugt die Aussenluft über einen in strichpunktierten Linien ange deuteten Filter und. Ansaugschalldämpfer 18 in der Richtung der Pfeile 19 an und stösst dieselbe in den Raum 20 aus, von dem aus ein Teil .der Luft den Kühlrippen 11 der Zylinder 1 und der andere Teil der Luft dem Aufladegeb'läse 9 zufliesst. Dieses Gebläse liefert die zur Aufladung und Spülung der Zylinder 1 nötige Luftmenge,
die den Zylin dern über die Leitung 12-, die teilweise strich punktiert gezeichnet ist, in der Ridhtung der Pfeile 13 und 14 zugeführt wird. Die Kühl luft verqässt die Räume der Zylinderkühlrip- pen 11 in der Richtung der Pfeile 1'5.
Zur Führung der Kühlluft sind die Führungs- schaufeln 16 vorgesehen sowie ,die FühTungs- flächen 21 und 212.
In dem Raum 20 können Rohrschlangen zur Kühlung des :Schmieröls angeordnet sein, was in der Zeichnung nicht dargestellt Ist. Auf der Welle 10 kann auch noch ein Abgas turbinenrad festgekeilt sein, .das die Energie der Abgase für,den Gebläseantrieb auszunüt zen. erlaubt. Das Aizfladegefläserad 9 kann direkt auf der -Welle 5 befestigt sein, wobei die Hohlwelle 10- entfällt.
In diesem Fall wird vorteilhaft das Ladegebläserad und auch das gühlgebläserad mit der Welle 5 durch eine federnde Kupplung verbunden.
Air-cooled, supercharged internal combustion engine. The invention relates to a scented, supercharged B: rennkraftmäschine, in which the cooling is effected by an axial fan, the charge is effected by a radial fan, and consists in the fact that the fan wheels of both fans are attached to a common shaft,
wherein the cooling air blower supplies the intake air for the supercharging blower.
In the drawing, a Ausführungsbei is playing the subject of the invention, namely: Fig. 1 shows a vertical in-line engine with the fans in plan, in section, Fig. 92 is the cross section through the Ma machine along line II-II of FIG.
The 14lotc cylinders 1 are arranged vertically and in series. The fans are driven by the flywheel side of the motor, where the speed fluctuations are smallest, namely via a gear wheel sitting on the flywheel 2, an intermediate wheel 17 and a pinion 4 which is on the:
along the motor next to the cylinders extending shaft 5 is stuck, .which can be designed as a gate sion spring bar. On the water shaft 5, the cooling fan wheel 6 is be strengthened, the end of the shaft 5 in the bearing 8 fixedly connected to the suction funnel 7 is mounted. The charging fan wheel 9 is loosely mounted on the shaft 5 and is firmly connected to the cooling fan wheel through the hollow shaft 10.
The cooling fan 6 sucks the outside air through a filter and indicated in dash-dotted lines. Intake silencer 18 in the direction of arrows 19 and expels the same into space 20, from which part of the air flows to the cooling fins 11 of the cylinder 1 and the other part of the air to the supercharger 9. This fan supplies the amount of air required for charging and flushing cylinder 1,
which the Zylin countries on line 12, which is partially drawn in dashed lines, in the direction of the arrows 13 and 14 is supplied. The cooling air leaves the spaces of the cylinder cooling fins 11 in the direction of the arrows 1'5.
The guide blades 16 and the guide surfaces 21 and 212 are provided for guiding the cooling air.
In the space 20 pipe coils for cooling the lubricating oil can be arranged, which is not shown in the drawing. An exhaust turbine wheel can also be wedged firmly on the shaft 10, so that the energy of the exhaust gases is used for the fan drive. allowed. The Aizfladegefläserad 9 can be attached directly to the shaft 5, the hollow shaft 10 being omitted.
In this case, the charging fan wheel and also the cooling fan wheel are advantageously connected to the shaft 5 by a resilient coupling.
