Abstract

The two pistons (3a, 3b) are rigidly coupled together by a push-rod (4) pref. having teeth (5) on both sides in mesh with corresp. teeth (7) on a shaft (8), which drives a gear train (9, 10) via an electronically controlled mechanical or magneto-hydraulic free-wheel coupling (8). The pistons execute compression and power strokes alternately so that their linear movement is converted into rotation of an output shaft (12). Their travel is equal to or greater than the piston dia. USE/ADVANTAGE - In stationary plants and motor vehicles, more favourable power/wt. ratio is achieved with greater output during fewer strokes.

Description

Die Erfindung betrifft einen Zweitakt-Hubkolbenmotor ohne Kurbeltrieb, der sowohl als stationärer Motor als auch in Kraftfahrzeugen eingesetzt werden kann.The invention relates to a two-stroke reciprocating engine without a crank mechanism, the can be used both as a stationary engine and in motor vehicles can.

Allgemein bekannt sind Hubkolbenmotoren mit Kurbeltrieb sowie Dreh­ kolbenmaschinen unter der Bezeichnung Wankelmotoren.Reciprocating engines with crank drive and rotation are generally known piston machines under the name Wankel engines.

Hubkolbenmotoren mit Kurbeltrieb besitzen eine Kurbelwelle mit Pleuel und Schwungrad. Leistungssteigerungen erfolgen meist durch eine Drehzahlerhö­ hung, indem der Kolbendurchmesser größer als der Kolbenhub ausgeführt wird. Diese Bauweise bedingt eine relativ hohe Motormasse. In der oberen Totpunktlage, zu Beginn des Arbeitstaktes, steht der Kolben mit Pleuel senk­ recht auf dem Pleuelzapfen, so daß nur eine Radialbelastung der Lager er­ folgt ohne Drehmoment an der Kurbelwelle. Nach Erreichen eines entspre­ chenden Kurbelwinkels, wenn der Verbrennungsdruck durch den Kolbenhub gemindert ist, erfolgt ein Drehmoment an der Kurbelwelle. Die Schrägstel­ lung des Pleuels zur Zylinderachse bewirkt einen radialen Druck auf den Kol­ ben, der zum einseitigen Verschleiß der Zylinderbohrung und des Kolbens führt.Reciprocating engines with crank drive have a crankshaft with a connecting rod and Flywheel. Increases in performance are usually achieved by increasing the speed hung by making the piston diameter larger than the piston stroke becomes. This design requires a relatively high engine mass. In the top Dead center position, at the beginning of the work cycle, the piston is lower with the connecting rod right on the conrod, so that only a radial load on the bearing follows without torque on the crankshaft. After reaching one appropriate crank angle when the combustion pressure by the piston stroke is reduced, there is a torque on the crankshaft. The slant the connecting rod to the cylinder axis causes a radial pressure on the piston ben, the one-sided wear of the cylinder bore and the piston leads.

Drehkolbenmaschinen besitzen ein gutes Masse-Leistungs-Verhältnis, haben sich jedoch wegen der Abdichtungsprobleme nicht durchgesetzt.Rotary lobe machines have a good mass-to-performance ratio however, did not prevail due to the sealing problems.

Ziel der Erfindung ist es, einen Zweitakt-Hubkolbenmotor zu schaffen, der die Nachteile des Kurbeltriebes nicht aufweist, ein günstigeres Masse-Lei­ stungs-Verhältnis und eine höhere Energieausbeute bei geringerer Hubzahl ermöglicht.The aim of the invention is to provide a two-stroke reciprocating engine that does not have the disadvantages of the crank mechanism, a cheaper mass lei performance ratio and a higher energy yield with a lower stroke rate enables.

Aufgabe der Erfindung ist ein Zweitakt-Hubkolbenmotor, bei dem die allge­ mein übliche mechanische Hubbegrenzung durch die Einleitung des Verbren­ nungsvorganges erfolgt und bei dem der Drehmomentradius während des Ar­ beitsspieles konstant bleibt. The object of the invention is a two-stroke reciprocating engine, in which the general my usual mechanical stroke limitation through the initiation of burning tion process takes place and in which the torque radius during the Ar example remains constant.  

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß zwei gegenüberlie­ gende Kolben starr miteinander verbunden sind zu einer Arbeitseinheit, wo­ bei wechselseitig der Arbeitshub des einen Kolbens den Kompressionshub des anderen Kolbens bewirkt und gleichzeitig die Arbeitsleistung an eine der beidseitig eingreifenden Wellen mit Freilauf übertragen wird. Durch ein am Freilauf befestigtes Zahnrad wird die Arbeitsleistung nur beim Arbeitshub an ein gemeinsames Abtriebszahnrad übertragen, während beim Kompressions­ hub der Freilauf ein Auskuppeln von der eingreifenden Welle bewirkt.According to the invention the object is achieved in that two opposite ing pistons are rigidly connected to one another where with the reciprocating stroke of one piston the compression stroke of the causes other pistons and at the same time the work performed on one of double-acting shafts are transmitted with freewheel. By an on Freewheel-mounted gear will only work on the power stroke a common output gear transmitted while in compression stroke freewheel disengages from the engaging shaft.

Bei Anordnung von zwei oder mehreren miteinander gekoppelten Arbeits­ einheiten wird eine Boxeranordnung erreicht, wobei der gegenüberliegende Kolben der anderen Arbeitseinheit ebenfalls einen Arbeitshub bzw. Kompres­ sionshub ausübt.When arranging two or more linked work units a boxer arrangement is achieved, with the opposite one Pistons of the other work unit also a working stroke or compress sionshub exercises.

Die Erfindung soll nachstehend an einem Ausführungsbeispiel näher erläutert werden. Dabei zeigt:The invention will be explained in more detail using an exemplary embodiment will. It shows:

Fig. 1 eine Ansicht der Arbeitseinheit von einem Zweitakt-Hubkolbenmotor ohne Kurbeltrieb, Fig. 1 is a view of the working unit of a two-stroke reciprocating engine without crank mechanism,

Fig. 2 eine Draufsicht der Arbeitseinheit von einem Zweitakt-Hubkolben­ motor ohne Kurbeltrieb. Fig. 2 is a plan view of the working unit of a two-stroke reciprocating engine without a crank mechanism.

Fig. 1 zeigt das Gehäuse 1 mit den stirnseitig befestigten Zylindern 2, in dem die lineare Bewegung der Kolben 3a und 3b, verbunden durch die Schub­ stange 4 (Zahnstange) mit den Mitnahme-Elementen 5 (Zähne) mittels der Wellen 6 mit den festverbundenen Mitnahme-Elementen 7 (Zahnräder) und dem auf den Wellen 6 befestigten Freilauf 8 mit Zahnrad 9 in eine Rotations­ bewegung umgesetzt wird. Fig. 1 shows the housing 1 with the front-mounted cylinders 2 , in which the linear movement of the pistons 3 a and 3 b, connected by the push rod 4 (rack) with the driving elements 5 (teeth) by means of the shafts 6 with The firmly connected driving elements 7 (gears) and the freewheel 8 fastened on the shafts 6 with the gear 9 are converted into a rotational movement.

Fig. 2 zeigt den Eingriff der beiden Zahnräder 9 in das Abtriebszahnrad 10 mit der Abtriebswelle 12. Zur Aufnahme der Schubstange 4 dienen die Füh­ rungen 11. Fig. 2 shows the engagement of the two gears 9 in the output gear 10 to the output shaft 12. For receiving the connecting rod 4 , the guides 11 are used .

Mit Einsetzen des Verbrennungsvorganges erfolgt der Arbeitshub des Kol­ bens 3a und der Kompressionshub des Kolbens 3b. Nach Erreichen der Dreh­ zahl des Zahnrades 9 durch die Welle 6 mit den Mitnahme-Elementen 7 wird der Freilauf 8 gesperrt und die Arbeitsleistung übertragen. Mit Abnahme der Kolbengeschwindigkeit vor Kompressionsende verringert sich die Drehzahl der Welle 6 mit den Mitnahme-Elementen 7, und der Freilauf 8 löst die Ver­ bindung zum Zahnrad 9. Die noch vorhandene Bewegungsenergie der Arbeitseinheit bewirkt die Restkompression. Durch den Freilauf 8 besteht keine starre Verbindung der Welle 6 zum Zahnrad 9, so daß über die Ab­ triebswelle 12 keine Bewegung der Schubstange 4 eingeleitet werden kann.When the combustion process begins, the working stroke of the piston 3 a and the compression stroke of the piston 3 b take place. After reaching the number of revolutions of the gear 9 through the shaft 6 with the driving elements 7 , the freewheel 8 is blocked and the work performed. As the piston speed decreases before the end of compression, the speed of the shaft 6 with the driving elements 7 decreases, and the freewheel 8 releases the connection to the toothed wheel 9 . The remaining kinetic energy of the work unit causes the residual compression. Due to the freewheel 8 there is no rigid connection of the shaft 6 to the gear 9 , so that from the drive shaft 12 no movement of the push rod 4 can be initiated.
