Description
Luftgekühlte Brennkraftmaschine Die Erfindung bezieht sich auf eine luftgekühlte Brennkraftmaschine mit einem einstöckigen, vorzugsweise aus Leichtmetall bestehenden und auf dem Kurbelgehäuse aufsitzenden Zylindergehäuse-Zylinderkopf-Stück und einer an ihrem kopfseitigen Ende an dem Zylinderkopf befestigten und Kühlrippen tragenden Laufbüchsen und besteht im wesentlichen darin, daß das Zylindergehäuse-Zylinderkopf-Stück in an sich bekannter Weise durch Zugankerschrauben am Kurbelgehäuse befestigt ist, die mindestens bis in das Gebiet des Zylinderkopfes reichen. Im einzelnen wird Hierzu noch vorgeschlagen, daß die Zugankerschrauhen durch Ausbuchtungen des Zylindergehäuse-Zylinderkopf-Stückes hindurchgeführt sind.Air-cooled internal combustion engine The invention relates to a air-cooled internal combustion engine with a one-story, preferably made of light metal existing and on the crankcase seated cylinder housing-cylinder head piece and one attached to the cylinder head at its head end and cooling fins bearing liners and consists essentially in the fact that the cylinder housing-cylinder head piece is attached to the crankcase in a manner known per se by tie bolts, which extend at least into the area of the cylinder head. This is done in detail still proposed that the tie rod screws through bulges of the cylinder housing-cylinder head piece are passed through.
Auf diese Weise wird trotz der einstöckigen Ausbildung des der Kühlluftführung um den Zylinder dienenden Zylindergehäuses mit dein Zylinderkopf und der damit verbundenen Vorteile vermieden, daß das Zylindergehäuse im Betrieb der Bremikraftniaschine durch die Gaskräfte auf Zug beansprucht \\#ird, was insbesondere bei Leichtmetallausführungen ungünstig ist. Bei der erfindungsgemäßen Anordnung geht der Kraftfluß vom Zylinderkopf direkt in die Zuganker, so daß nicht nur die Zylinderlaufbüchse, sondern auch das Zylindergehäuse selbst keine Zugspannung erhält. Die Zylinderlaufbüchse erhält überhaupt keine Spannungen aus den Gaskräften und kann sich frei ausdehnen; das Zylindergehäuse wird lediglich auf Druck infolge der Vorspannung der Zugankerverbindung beansprucht.In this way, despite the one-story design of the cooling air duct around the cylinder serving cylinder housing with your cylinder head and the associated Advantages avoided that the cylinder housing through during operation of the Bremikraftniaschine the gas forces on train \\ # ird, which is especially true for light metal designs is unfavorable. In the arrangement according to the invention, the power flow goes from the cylinder head directly into the tie rod, so that not only the cylinder liner, but also that The cylinder housing itself does not receive any tensile stress. The cylinder liner gets at all no tension from the gas forces and can expand freely; the cylinder housing is only subjected to pressure as a result of the prestressing of the tie rod connection.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Es zeigt Fig. 1 die Ansicht auf einen erfindungsgemäß ausgebildeten Zylinder, Fig. 2 einen Querschnitt durch diesen Zylinder entsprechend der Schnittlinie II-II in Fig. 1 und Fig. 3 einen Längsschnitt durch den Zylinder entsprechend der Schnittlinie III-III in Fig. 2.The drawing shows an exemplary embodiment of the subject matter of the invention shown. 1 shows the view of one designed according to the invention Cylinder, Fig. 2 shows a cross section through this cylinder according to the cutting line II-II in Fig. 1 and Fig. 3 shows a longitudinal section through the cylinder corresponding to the Section line III-III in FIG. 2.
Das aus Leichtmetall bestehende Zylindergehäuse-Zylinderkopf-Stück 10 sitzt mit einem Flansch 11 auf dem Kurbelgehäuse 12 auf. In das Kurbelgehäuse eingeschraubte Zugankerschrauben 13 erstrecken sich bis in das Gebiet des Zylinderkopfes und befestigen das Zylindergehäuse-Zylinderkopf-Stück 10 unter Druckvorspannung des den verrippten Bereich der Laufbüchse umfassenden Teils dieses Stückes am Kurbelgehäuse. In dem Zylinderkopfteil des Stückes 10 ist eine Laufbüchse 14 eingeschraubt, die sich gegenüber dem Kurbelgehäuse 12 dichtend in Längsrichtung frei verschieben kann. Die Laufbüchse 14 trägt Kühlrippen 15.The cylinder housing-cylinder head piece made of light metal 10 sits with a flange 11 on the crankcase 12. In the crankcase screwed tie rod bolts 13 extend into the area of the cylinder head and fasten the cylinder housing-cylinder head piece 10 under compressive prestress of the part of this piece on the crankcase comprising the ribbed area of the liner. In the cylinder head part of the piece 10, a liner 14 is screwed, which can move freely in the longitudinal direction with respect to the crankcase 12 in a sealing manner. The liner 14 carries cooling fins 15.
Die Zuganker 13 sind durch Ausbuchtungen 16 des Zylindergehäuse-Zylinderkopf-Stückes hindurchgeführt.The tie rods 13 are through bulges 16 of the cylinder housing-cylinder head piece passed through.
