Gehäusemantel für eine Rotationskolben-Brennkraftmaschine Housing jacket for a rotary piston internal combustion engine
Die Erfindung bezieht sich auf einen Gehäusemantel für eine Rotationskolben-Brennkraftmaschine, insbesondere für eine Brennkraftmaschine in Trochoidenbauart, der eine Laufbahn für den Kolben aufweist und an dessen Seitenwänden beidseitig in Achsrichtung Seitenteile angesetzt sind.The invention relates to a housing jacket for a rotary piston internal combustion engine, in particular for one Internal combustion engine in trochoid design, which has a raceway for the piston and on its side walls on both sides side panels are attached in the axial direction.
Bei Rotationskolben-Brennkraftmaschinen in Trochoidenbauart wurde beobachtet, daß sich die Seitenteile verformen, weil der Gehäusemantel, der im Bereich der Verdichtungskammer und der Expansionskammer sehr viel heißer wird als im Bereich der Ansaugkammer, sich unregelmäßig ausdehnt und sich verzieht. Der größte Verzug entsteht dabei im Bereich der Laufbahn für den Kolben. Die Folge davon ist ein Verzug der Seitenteile, die im Interesse einer guten Ölabdichtung vollkommen eben bleiben sollten.For rotary piston internal combustion engines of the trochoid design it was observed that the side parts are deformed because of the housing jacket, which is in the area of the compression chamber and the expansion chamber is much hotter than in the area of the suction chamber, expanding and expanding irregularly warps. The greatest distortion occurs in the area of the raceway for the piston. The consequence of this is a distortion of the side parts, which should remain perfectly level in the interests of a good oil seal.
Die Erfindung macht es sich zur Aufgabe, den Gehäusemantel derart auszubilden, daß sich seine unregelmäßigen Ausdehnungen in der Nähe der Laufbahn nicht auf die Seitenteile des Brennkraftmaschinengehäuses auswirken. Die gestellte Aufgabe wird in einfacher Weise dadurch gelöst, daß in jeder Seitenwand des Gehäusemantels dicht neben der Laufbahn und parallel zu dieser mindestens eine ganz oder teilweise umlaufende Nute vorgesehen ist.The invention makes it its task to design the housing jacket in such a way that its irregular dimensions in the vicinity of the raceway, not on the side parts of the internal combustion engine housing impact. The problem posed is achieved in a simple manner in that in each side wall of the housing jacket close to the track and parallel to this at least one completely or partially circumferential groove is provided.
Durch Anordnung mindestens einer Nute kann sich der Rand des Gehäusemantels im Bereich der Laufbahn bei Erwärmung verformen, ohne daß ein Druck auf die Seitenteile ausgeübt wird, der die Seitenteile verformen könnte.By arranging at least one groove, the edge of the housing jacket can move in the area of the raceway when it is heated deform without any pressure being exerted on the side parts which could deform the side parts.

In vorteilhafter Ausgestaltung des Erfindungsgegenstandes kann die Nute lediglich im heißen Bogen des Gehäusemantels angeordnet sein, z.B. im Bereich zwischen der Zündkerze und dem Auslaßkanal. In an advantageous embodiment of the subject matter of the invention, the groove can only be arranged in the hot curve of the housing jacket e.g. in the area between the spark plug and the exhaust port.
In der Zeichnung ist der Gegenstand der Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the subject of the invention is in one embodiment shown.

Das Gehäuse einer Rotationskolben-Brennkraftmaschine in Trochoidenbauart wird nach den Fig. Iu. 2 im wesentlichen von dem Gehäasemantel 1 und von den beiden Seitenteilen 2 gebildet, die in Achsrichtung an den Gehäusemantel 1 angesetzt sind. Der Gehäusemantel 1 ist mit der Laufbahn 3 ausgestattet, an welcher der Kolben der Brennkraftmaschine bei seinem Umlauf entlanggleitet. Ln Interesse einer sicheren Ölabdichtung zwischen den Stirnwänden des Kolbens und den Seitenwänden 4 oder der Seitenteile 2 ist es notwendig, daß die Seitenwände 4 vollkommen eben bleiben. Es darf demnach kein Verzug eintreten, der dadurch hervorgerufen wird, daß der Gehäusemantel 1 sich in der Nähe seiner Laufbahn 3 durch den Betriqb der Brennkraftmaschine erwärmt und gegen die .Seitenwände 4 der Seitenteile 2 drückt« Zur Vermeidung des Verzuges der Seitenwände 4 ist in jeder Seitenwand 5 des Gehäusemantels 1 in einem ringsum kleinen Abstand 6 zur Laufbahn 3 die im Querschnitt recht-The housing of a rotary piston internal combustion engine in trochoid design is shown in FIGS. 2 essentially formed by the housing jacket 1 and by the two side parts 2, which are attached to the housing jacket 1 in the axial direction are. The housing jacket 1 is equipped with the raceway 3, on which the piston of the internal combustion engine at slides along its orbit. In the interests of a safe Oil seal between the end walls of the piston and the side walls 4 or the side parts 2, it is necessary that the Side walls 4 remain completely flat. There must therefore be no delay that is caused by the fact that the housing jacket 1 is heated in the vicinity of his career 3 by the Betriqb of the internal combustion engine and against the .Seite walls 4 of the Side parts 2 presses «To avoid distortion of the side walls 4 is in each side wall 5 of the housing shell 1 in one all around a small distance 6 to the raceway 3 which is right in cross-section

eckige Nute 7 vorgesehen. Zwischen jeder Nute 7 und der Laufbahn wird von den Seitenwänden 5 des Gehäusemantels 1 ein Rand 8 gebildet, der so schmal ist, daß er keine großen Kräfte übertragen kann. Dieser Rand 8 verformt sich, wenn der Gehäusemantel 1 sich im Bereich seiner Laufbahn 3 in Achsrichtung ausdehnt, so daß auf die Seitenwände 4 der Seitenteile 2 kein Druck ausgeübt wird*angular groove 7 is provided. Between each groove 7 and the raceway, an edge 8 is formed by the side walls 5 of the housing shell 1, which is so narrow that it cannot transmit great forces. This edge 8 deforms when the housing jacket 1 is expands in the area of its track 3 in the axial direction, so that no pressure is exerted on the side walls 4 of the side parts 2 *
Nach Fig. 3 reicht es aus, wenn die Nuten 7 in den Seitenwänden des Gehäusemantels 1 sich lediglich im Bereich des sogenannten heißen Bogens 9 etwa zwischen der Zündkerze 10 und dem Auslaßkanal 11 erstrecken.According to Fig. 3, it is sufficient if the grooves 7 in the side walls of the housing jacket 1 are only in the area of the so-called The hot arc 9 extends approximately between the spark plug 10 and the outlet duct 11.
Gegebenenfalls können an Stelle einer Nute in jeder Seitenwand des Gehäusemantels zwei in geringem Abstand parallel zueinander angeordnete Nuten vorgesehen sein« If necessary, instead of a groove in each side wall of the Two grooves arranged parallel to each other at a short distance from each other should be provided "
