Abstract

The rotary piston engine (1) has a cylinder formed in a rotating housing. The housing rotates about an axis which is at right angles to the cylinder axis and intersects the cylinder axis at a point near the inner end of the cylinder. The piston, which operates inside the cylinder, has its piston rod connected to a ring which rotates about an axis parallel to the axis of rotation of the cylinder housing. The stroke of the piston is equal to twice the distance between the two axes of rotation. USE/ADVANTAGE - Because the piston does not move radially relative to the outer ring the engine can be dynamically balanced.

Description

Der Hubkolbenmotor ist zur Zeit führend in der Technologie der KFZ-Verbrennungsmotoren. Aber auch der Wankelmotor wurde eingehend auf seine Tauglichkeit beim Einsatz in Kraftfahrzeugen geprüft.The reciprocating engine is currently the leader in technology of automotive internal combustion engines. But also the Wankel engine has been detailed on its suitability for use in Motor vehicles checked.

Der entscheidende Vorteil eines Rotationskolbenmotors liegt darin, daß der Kolben ausschließlich rotierende Bewegungen ausführt, und so durch Gegengewichte ein völliger Masseaus­ gleich vorgenommen werden kann. Dadurch erreicht man eine gute Laufkultur und hohe Drehzahlen. Desweiteren minimiert man den Leistungsverlust, der beim Beschleunigen und Abbremsen des Kolbens auftritt, wenn er eine geradlinige Bewegung ausführt. Der größte Nachteil ist das ungünstige Verhältnis des nutzbaren Volumens zur abzudichtenden Oberfläche. Dies führt zu Leistungsverlust und erhöhtem Kraftstoffverbrauch.The decisive advantage of a rotary piston engine is in that the piston only has rotating movements executes, and so by counterweights a total mass can be made immediately. This way you get a good one Running culture and high speeds. Furthermore, you minimize the loss of power when accelerating and braking the Piston occurs when he makes a straight movement. The main disadvantage is the unfavorable ratio of the usable volume to the surface to be sealed. this leads to loss of performance and increased fuel consumption.

Bei der Entwicklung des Hubkolbenmotors wurden in der Technik schon entscheidende Fortschritte gemacht, so daß man kaum noch von Nachteilen reden kann. Trotzdem wäre es von Vorteil, wenn man die Vorzüge von Hubkolbenmotor und Rotationskolbenmotor vereinen könnte.In the development of the reciprocating engine were in engineering already made decisive progress so that you can hardly can talk about disadvantages. Nevertheless, it would be an advantage if the advantages of a reciprocating piston engine and a rotary piston engine could unite.

Die Lösung dieses Problems wird durch die Zeichnungen näher erläutert (1), (2). Funktionsgrundlage des Motors ist ein konventioneller Hub­ kolbenmotor. Zylinder und Kolben sind auf je einer Kreis­ scheibe befestigt, welche einseitig gelagert sind und sich mit gleicher Drehzahl und Drehsinn bewegen.The solution to this problem is illustrated by the drawings explains (1), (2). The motor is based on a conventional stroke piston engine. Cylinder and piston are on a circle disc attached, which are supported on one side and with move at the same speed and direction.

Die Kreisscheiben sind an je einer Welle befestigt, welche sich gegenüberstehen, aber um einen Abstand e versetzt sind. Bei gleichmäßiger Drehung des Motors erhält man so einen Hub von 2e. Wichtig ist, daß über ein spezielles Getriebe (3) ein Winkelzwang erfolgen muß, damit sich Kolben und Zylinder stets optimal gegenüberstehen. Die beiden Kreisscheiben benötigen zur Durchführung des geplanten Bewegungsablaufes eine partiell unterschiedliche Winkelgeschwindigkeit. The circular disks are each attached to a shaft, which face each other, but are offset by a distance e. With an even rotation of the motor you get a stroke of 2e. It is important that a special gear ( 3 ) must be used to ensure that the pistons and cylinders are always optimally opposed to each other. The two circular disks require a partially different angular velocity to carry out the planned motion sequence.

Das Merkmal dieses Getriebes besteht darin, daß zwei Zahnräder so außermittig gelagert sind, daß die geforderten Winkel­ differenzen zu jedem Zeitpunkt des Bewegungsablaufes erreicht werden.The feature of this transmission is that two gears are mounted so that the required angle differences achieved at any time during the movement will.

Um an der Abtriebswelle eine gleichmäßige Drehzahl zu er­ reichen, wird ein Konventionelles Differentialgetriebe in um­ gekehrter Betreiberrichtung eingesetzt, (4) so daß sich die beiden unterschiedlichen Drehzahlen zu einer gleichbleibenden Gesamtdrehzahl vereinen. Ein weiterer Vorteil des Differen­ tials besteht darin, daß bei einem Trägheitsausgleich zwischen Kolben incl. Kolbengetriebe und Zylinder incl. Zylinderge­ triebe die Kinetische Energie der einen Seite bei Drehzahler­ niedrigung zur Drehzahlerhöhung der anderen Seite genutzt werden kann. Dadurch muß keine zusätzliche Leistung vom Motor aufgewendet werden, wenn eine partielle Beschleunigung der Winkelgeschwindigkeit auftritt. (Das gilt nicht für eine Erhöhung der Gesamtdrehzahl). An jeder Kreisscheibe kann nur je ein Zylinder bzw. Kolben befestigt werden, da es keine weiteren Punkte gibt, an denen sie sich in dem notwendigen Winkeln gegenüberstehen würden.In order to achieve a constant speed on the output shaft range, a conventional differential gear in around reversed operator direction used (4) so that the two different speeds to a constant Combine total speed. Another advantage of the difference tials is that in the case of an inertia compensation between Pistons incl. Piston gear and cylinder incl drive the kinetic energy on the one hand at speeder reduction used to increase the speed of the other side can be. This means that no additional power is required from the engine be used when a partial acceleration of the Angular velocity occurs. (This does not apply to one Increase in total speed). At each circular disc only One cylinder or piston are attached since there are none there are other points at which they are in the necessary Would face angles.

Bei Einsatz eines zweiten Motors könnte man die beiden Ab­ triebe erst nach dem Differential zusammenführen, wenn die Takte nicht um genau 360° verschoben sind. Bei Gleichtakt oder 360° Verschiebung ist eine Vereinigung schon vor dem Zwang möglich.If a second motor is used, the two Ab drives only after the differential merge when the Bars are not shifted by exactly 360 °. With common mode or 360 ° shift is a union before Coercion possible.

Ein Ausführungsvorschlag: Vier Zylinder mit je um 180° ver­ setztem Takt. Dazu werden je zwei Zylinderpaare (erster und dritter Takt sowie zweiter und vierter Takt) vor dem Winkel­ zwang vereinigt. Die beiden so erhaltenen Teilleistungen führt man nach dem Differentialgetriebe auf eine gemeinsame Welle.A design suggestion: four cylinders with 180 ° ver set beat. Two pairs of cylinders (first and third bar and second and fourth bar) before the angle forced united. The two partial services thus obtained one leads to a common one after the differential gear Wave.

Die Kraftstoffzufuhr des Motors sowie die Abgasentsorgung müßte über die beiden Wellen erfolgen, an denen die Kreis­ scheiben befestigt sind. Die Zündung erfolgt durch Induktion einer sich mitdrehenden Spule.The engine's fuel supply and exhaust system would have to be done over the two waves on which the circle discs are attached. The ignition takes place by induction a rotating spool.
