Description

Luftgekühlter Brennkräftmaschinenzylinder Beim Bau von luftgekühlten Motoren hat man bisher, wie die Entwicklungsgeschichte zeigt, die Forderung ,einer kräftigen Kühlung des Zylinders und die Forderung, den Zylinder so zu befestigen, daß er nicht im Kraftfluß liegt, völlig getrennt voneinander behandelt und jede dieser beiden Forderungen für sich betrachtet zu erfüllen gesucht. So suchte man eine möglichst wirksame Kühlung dadurch zu erreichen, daß man den Zylinder sowohl am Umfang- wie am Boden mit Rippen versah und über den rippenbesetzten Teil des Zylinders eine Haube herübersetzte, durch die Kühlluft hindurchgeblasen wurde. Was die zweite der genannten Forderungen betrifft, hat man vorgeschlagen, -den Zylinder an seinem oberen Ende auf Säulen oder Abstandhülsen aufzulegen und ihn mit Hilfe von durch diese Hülsen hindurchgeführten Bolzen, die am Kurbelgehäuse befestigt waren, gegen die Auflageflächen zu pressen.Air-cooled internal combustion engine cylinder In the construction of air-cooled engines, as the history of development shows, the requirement for strong cooling of the cylinder and the requirement to fasten the cylinder in such a way that it is not in the power flow have been dealt with completely separately from each other and each of these two requirements sought to be fulfilled in and of itself. An attempt was made to achieve the most effective cooling possible by providing the cylinder with ribs both on the circumference and on the bottom and by placing a hood over the ribbed part of the cylinder through which cooling air was blown. As to the second of these demands, it has been proposed - hang up the cylinder at its upper end on pillars or spacers and press it with the help of which is passed through these sleeves bolts were fastened to the crankcase, against the bearing surfaces.

Gemäß der Erfindung wird nun vorgeschlagen, bei Anwendung einer ähnlichen Art der Zylinderbefestigung diese so auszugestalten, daß zugleich damit besonders günstige Kühlbedingungen für den Zylinder geschaffen werden. Erfindungsgemäß wird das dadurch erreicht, daß der Zylinder, in einem rohrförmigen Luftführungsmantel an einem Bund in Höhe des Bodens gelagert, durch eine über die Bodenrippen gelegte Platte mit in bekannter Weise am Kurbelgehäuse befestigten Zugbolzen gegen den Bund gepreßt wird. Bei dieser Anordnung werden also Teile, die der Lagerung oder Befestigung des. Zylinders dienen, nämlich die über die Bodenrippen gelegte Platte und der Abstandhalter, durch den die Zugbolzen hindurchgehen und auf den sich der Zylinderboden. mit seinem Bund auflegt, zur Bildung von Luftführungskanälen herangezogen. Diese Anordnung stellt somit eine Lösung der beiden eingangsaufgeführten Aufgaben dar, mit dem Ergebnis, daß man auf diese Weise einen sehr einfachen und übersichtlichen Gesamtaufbau für die Maschine erzielt.According to the invention it is now proposed, using a similar one Type of cylinder attachment to design this so that at the same time so special favorable cooling conditions for the cylinder are created. According to the invention this is achieved in that the cylinder is in a tubular air duct jacket stored on a collar at the level of the floor, through one laid over the floor ribs Plate with tension bolts attached to the crankcase in a known manner against the collar is pressed. In this arrangement, parts that are used for storage or attachment serve the cylinder, namely the plate placed over the bottom ribs and the spacer, through which the tension bolts pass and on which the cylinder base is located. with his The federal government is in place, used to form air ducts. This arrangement thus represents a solution to the two tasks listed above, with the result, in this way a very simple and clear overall structure for the machine achieved.

Ein Ausführungsbeispiel der Erfindung ist in den Abbildungen dargestellt. Die Laufbuchse des Zylinders ist mit i bezeichnet. Der Zylinder trägt in bekannter Weise am Umfang eine Reihe von Rippen 2. Ferner weist er eine Reihe von Bodenrippen 3 auf. Er ist in einen Mantel q. geführt, der zugleich der Führung der Kühlluft dient. Auf die Bodenrippen 3 ist. eine Platte 5 aufgelegt, die ebenfalls zugleich die Aufgabe hat, die Kühlluft, die den Zylinderboden umspült, zu führen. Der Zylinder ist bei 6 gelagert. Er wird mit Hilfe der Zugbolzen 7, die am Kurbelgehäuse angreifen, der Platte 5 und der Rippen 3 auf seine Auflage niedergepreßt. Der Verlauf der Bodenrippen 3 ist in Fig. 2 schematisch angedeutet.An embodiment of the invention is shown in the figures. The cylinder liner is denoted by i. The cylinder wears in well-known Way on the circumference a number of ribs 2. It also has a number of bottom ribs 3 on. He is in a coat q. out, which at the same time the guidance of the cooling air serves. On the bottom ribs 3 is. a plate 5 is placed, which is also at the same time has the task of guiding the cooling air that washes around the cylinder base. The cylinder is stored at 6. It is secured with the help of the tension bolts 7, which engage the crankcase, the plate 5 and the ribs 3 pressed down on its support. The course of the floor ribs 3 is indicated schematically in FIG. 2.
