Abstract

An internal combustion engine has an axial cylinder assembly arranged around an eccentring shaft. The same fluid is used for lubricating and for cooling and can be supplied to the places to be lubricated and cooled from the inside of the eccentric shaft as well as from the outside to the cylinders and cylinder heads.

Description

Es sind keine Verbrennungsmotoren mit axialer Zylinderanordnung um eine Tamelwelle herum mit einem taumelscheibenartigen Kurbeltrieb bekannt, die Schmierung und Kühlung des Motors mit dem gleichen flüssigen Medium vorschlagen. Die DE-OS 2736023 hat keine Kühlung und Schmierung mit dem gleichen Medium, während die DE-OS 2825870 keinen Taumelscheibentrieb vorstellt. Bei Verbrennungsmotoren mit Taumelscheibentrieb, die bekanntlich gewicht-leistungsmäßig sehr kompakt bauen, interessiert die Frage un steht die Aufgabe, am Baugewicht enzusparen und die gesamten Schmierungs- und Kühlungsvorrichtungen zu vereinfachen. Dies kann mit einer gemeinsamen Kühl- und Schmieranordnung erreicht werden. Zweck der Erfindung ist weiter die Vereinfachung der Kreisläufe, die flexibel für unterschiedliche Kühlanforderugen (Flugzeug- oder LKW-, Aggregats- oder Schiffsmotor) sein sollen, sowie die Anwendung einer wärmedämmenden Motorentechnologie für Kühlung und Schmeirung von Axialmotoren.There are no known internal combustion engines with an axial cylinder arrangement around a tamel shaft with a swashplate-like crank mechanism that propose lubrication and cooling of the engine with the same liquid medium. DE-OS 2736023 has no cooling and lubrication with the same medium, while DE-OS 2825870 does not introduce a swash plate drive. In the case of internal combustion engines with a swashplate drive, which are known to be very compact in terms of weight and performance, the question is of interest and the task is to save on the construction weight and to simplify the entire lubrication and cooling devices. This can be achieved with a common cooling and lubrication arrangement. The purpose of the invention is further to simplify the circuits, which should be flexible for different cooling requirements (aircraft or truck, unit or ship engine), as well as the use of a heat-insulating motor technology for cooling and lubrication of axial motors.

Die Lösung der Aufgabe ist dem Anspruch 1 zu entnehmen. Sie besteht darin, daß das gleiche Medium für Kühlung und Schmierung verwendet wird, wobei der Kreislauf des Mediums aufgezweigt wird in einen inneren und einen äußeren Kreislauf und diese Aufzweigung der Wege im Steuergehäuse und Lagerstuhl erfolgt, und weiter in der Anordnung einer zentralen Verteilernut, bei der die verschiedenen Kühl- und Schmierkreislauf-Kombinationen durch einfaches Umstecken von Querschnittssperren frei gewählt werden können, ohne Bauteilvarianten hervorbringen zu müssen. Die Erfindung ist anhand eines Beispieles am besten zu verstehen.The solution to the problem can be found in claim 1. It consists in that the same medium is used for cooling and lubrication, the circuit of the medium being branched into an inner and an outer circuit and this branching of the paths in the control housing and bearing bracket, and further in the arrangement of a central distributor groove, at which the various cooling and lubrication circuit combinations can be freely selected by simply repositioning cross-section locks without having to produce component variants. The invention is best understood using an example.

Fig. 1 zeigt eine Hälfte eines Axialmotor, der die oszillierende Bewegung der Kolben (13) in den Zylidern (14), die axial um eine Taumelwelle (15) herum angeordnet sind, in eine Drehung der Taumelwelle umsetzt. Die Zylinder werden durch Köpfe (16) abgedeckt und diese ihrerseits von einem Steuergehäuse (17), welches gleichzeitig über den Lagerstuhl (18) mit dem Motorgehäuse (34) verbunden ist. Das Steuergehäuse auf jeder Motorseite weist zwei Ölpumpen (1) und (2) auf, welche von der Kurbelwelle (15) angetrieben werden. Durch in Fig. 2 beschriebenes Verfahren gelangt das Öl in Pfeilrichtung entweder in die Kurbelwelle (über Raum (19)) und bildet einen Schmier- und Spritzölkreislauf, oder es gelangt in Ringraum (20) und bildet den Kühlkreislauf.Fig. 1 shows one half of an axial motor, which converts the oscillating movement of the pistons (13) in the cylinders (14), which are arranged axially around a wobble shaft (15), into a rotation of the wobble shaft. The cylinders are covered by heads (16) and these in turn by a control housing (17) which is connected to the motor housing (34) via the bearing bracket (18) at the same time. The control housing on each engine side has two oil pumps (1) and (2) which are driven by the crankshaft (15). By means of the method described in FIG. 2, the oil either reaches the crankshaft in the direction of the arrow (via space (19)) and forms a lubricating and spray oil circuit, or it reaches ring space (20) and forms the cooling circuit.

KühlkreislaufCooling circuit

Von Ringraum (20) fließt das Öl in die Ringräume (21) der einzelnen Zylinder. Diese Ringräume (21) dienen der Umspülung des Zylinderbereichs, der durch die Kolbenkrone von Spritzöl (22) ständig abgedeckt ist. Das Öl gelangt in eine Ringsammelnut (23) im Kopf (16), von der es durch eine Bohrung (24) in das Steuergehäuse (17) fließt, von wo es zurück in den Ölbehälter (25) gelangt. Die Ringräume (20) auf beiden Seiten sind durch Rohre (26) verbunden.The oil flows from the annular space (20) into the annular spaces (21) of the individual cylinders. These annular spaces (21) serve to wash around the cylinder area, which is constantly covered by the piston crown of spray oil (22). The oil enters an annular collecting groove (23) in the head (16), from which it flows through a bore (24) into the control housing (17), from where it returns to the oil container (25). The annular spaces (20) on both sides are connected by pipes (26).

Schmier- und SpritzölkreislaufLubrication and spray oil circuit

Durch die Taumelwelle (15) kann das Öl von einer Seite von Ringraum (19) auf die andere Seite fließen und gewährleistet eine Schmierung der Grundlager. Im Kubelzapfen befinden sich Bohrungen (27), durch die das Öl in den Raum zwischen Zapfen und einer Hülse (33) gelangt, auf der einzelne Pleuel (29) schwenkbar gelagert sind. Durch in Fig. 3 beschriebenes Verfahren gelangt das Öl durch Pendelring (28) und Pleuel (29) in den Bolzen (30) und von da in das Verbindungsstück (31) beider Kolben. Heirdruch kann allen bewegten Teilen Schmierung zugeführt werden. Durch Spritzdüsen tritt das Öl am Teil (31) aus und kühlt und schmiert Kolben und Zylinderwand durch einen darauf gerichteten Strahl (22). Das so durch Schmieren und Spritzen verlorene Öl sammelt sich im Gehäuse (18) und wird dem Ölbehälter (25) zugeführt.The oil can flow from one side of the annular space (19) to the other side through the swash shaft (15) and ensures lubrication of the base bearings. There are bores (27) in the cube pin through which the oil reaches the space between the pin and a sleeve (33) on which individual connecting rods (29) are pivotably mounted. By the method described in FIG. 3, the oil passes through the pendulum ring (28) and connecting rod (29) into the bolt (30) and from there into the connecting piece (31) of both pistons. Heurruch can lubricate all moving parts. The oil emerges from the part (31) through spray nozzles and cools and lubricates the piston and cylinder wall by means of a jet (22) directed thereon. The oil thus lost through lubrication and spraying collects in the housing (18) and is fed to the oil container (25).

Fig. 2 (Schnitt A-A) zeigt einen Schnitt des Ringraumes (32) in Lagerstuhl (18) und schematisch die auf diesen Ringraum mündenden Bohrungen (Fig. 2). Die im Steuergehäuse eingebauten Ölpumpen (1) und (2) saugen das Öl aus dem Ölbehälter und befördern es in den Ringraum (32).Fig. 2 (section A-A) shows a section of the annular space (32) in the bearing bracket (18) and schematically the holes opening onto this annular space (Fig. 2). The oil pumps (1) and (2) installed in the control housing draw the oil from the oil tank and convey it into the annular space (32).

Die sternförmig nach außen führenden bzw. von außen kommenden Bohrungen sind: Leitugen von Pumpe (1) und (2) und Leitungen (3), (4) und (11) für Anschlüsse externer Geräte wie Filter, Kühler, Thermostat und Manometer. Die Bohrungen (10) führen das Öl ins Innere der Taumelwelle (15) über Raum (19), und die Bohrung (9) verbindet den Ringraum (32) mit dem Ringraum (20) auf der Rückseite des Lägerstuhls (18). Die Bohrungen (38) führen jeweils zu Überdruckventilen. Der Ringraum ist durch fünf herausnehmbare Sperrklötze (5), (6), (7), (8) und (12) in Ringabschnitte aufgeteilt. Folgende Anordnungen sind möglich, (Klötze (5) und (8) bleiben dabei stets in der gezeigten Position):The star-shaped bores leading to the outside or coming from the outside are: lines for pumps (1) and (2) and lines (3), (4) and (11) for connections to external devices such as filters, coolers, thermostats and pressure gauges. The holes (10) lead the oil into the inside of the swash shaft (15) via space (19), and the hole (9) connects the annular space (32) with the annular space (20) on the back of the bearing chair (18). The holes (38) each lead to pressure relief valves. The ring space is divided into ring sections by five removable locking blocks (5), (6), (7), (8) and (12). The following arrangements are possible (blocks (5) and (8) always remain in the position shown):

Anordnung 1: Pumpe (1) und (2) als Sechmierölpumpen (mit Filterung und Kühlung): (6) wird entfernt (Anschluß (11) dicht): Öl fließt über (3) zum Filter und Kühler nach (4) und durch Löchern (10) in die Taumelwelle. Bohrung (9) ist durch Klötze (12) und (8) gesperrt (wird nur eine Pumpe benutzt, werden die Anschlüsse der anderen verschlossen).Arrangement 1: Pump (1) and (2) as six-oil pumps (with filtering and cooling): (6) is removed (connection (11) tight): Oil flows through (3) to the filter and cooler to (4) and through holes (10) into the wobble wave. Bore (9) is blocked by blocks (12) and (8) (if only one pump is used, the connections of the others are closed).

Anordnung 2: Pumpe (1) und (2) als Kühlölpumpe (ohne Filterung und Kühlung) (12), (6) und (7) werden entfernt: Öl fließt direkt nach (9). (3), (4) und (11) werden dichtgemacht (wird nur eine Pumpe benutzt, wird der Ansaug der anderen verschlossen).Arrangement 2: Pump (1) and (2) as cooling oil pump (without filtering and cooling) (12), (6) and (7) are removed: oil flows directly to (9). (3), (4) and (11) are sealed (if only one pump is used, the suction of the other is closed).

Anordnung 3: Pumpe (1) und (2) als Kühlölpumpe, mit Kühlung: (12) und (6) werden entfernt ((4) ist dicht): Öl fließt über (3) und Kühler nach (11).Arrangement 3: Pump (1) and (2) as cooling oil pump, with cooling: (12) and (6) are removed ((4) is tight): Oil flows over (3) and cooler after (11).

Anordnung 4: Pumpe (1) als Schmierölpumpe mit Filterung und Kühlung, Pumpe (2) als Kühlölpumpe ohne Filterung und Kühlung: (12) und (7) werden entfernt ((11) ist dicht): Öl fließt als Kühlöl direkt nach (9). Öl fließt über (3) zum Filter und Kühler nach (4) und in Löchern (10) in die Taumelwelle.Arrangement 4: Pump (1) as a lubricating oil pump with filtering and cooling, Pump (2) as a cooling oil pump without filtering and cooling: (12) and (7) are removed ((11) is tight): Oil flows directly to (9) as cooling oil. Oil flows via (3) to the filter and cooler after (4) and in holes (10) in the swash shaft.

Anordnung 5: Pumpe (1) als Schmierölpumpe mit Filterung und Kühlung, Pumpe (2) als Kühlölpumpe mit Kühlung: (7) wird entfernt: Öl fließt als Kühlöl über (11) und Kühler nach Anschluß (11) der anderen Seite und Bohrung (9) der anderen Seite. Öl fließt als Schmieröl wie Anordnung 4.Arrangement 5: Pump (1) as a lubricating oil pump with filtering and cooling, pump (2) as a cooling oil pump with cooling: (7) is removed: Oil flows as cooling oil via (11) and cooler to connection (11) on the other side and bore ( 9) the other side. Oil flows as lubricating oil like arrangement 4.

Kombinationen dieser Anordnungen auf beiden Motorseiten sind beispielsweise Kombination der Anordnung 1 mit 2 oder 3. Es ist für die Fertigung der Bauteile von Vorteil, daß eine 100% Dichtheit der jeweiligen Abschnitte und Kreisläufe zueinander nicht erforderlich ist, da es sich um das gleiche Medium handelt.Combinations of these arrangements on both engine sides are, for example, a combination of arrangement 1 with 2 or 3. It is advantageous for the manufacture of the components that 100% tightness of the respective sections and circuits to one another is not necessary since the medium is the same .

Fig. 3 zeigt einen Pendelring (28), über den das Öl aus der drehenden Taumelwelle (15) und die sich drehende Stützhülse (33) einen Weg findet in das eine Pendelbewegung ausführende Pleuel (29). Dieser Pendelring (28) hat an seiner Innenseite eine umlaufende Sammelnut, von der aus über Stichbohrungen (35) das Öl in die Pleuelölbohrung (36) gelangt. Die Anfasung der Bohrung (35) an der Kontaktfläche Pendelring/Pleuel ist so groß, daß auch bei maximalem Pendelausschlag noch satändig Öl fließt. Der Ring (28) ist gegen Verdrehung durch die Stifte (37) gesichert, die ihm jedoch genügend Spiel zum Ausgleich der Pendelbewegung lassen.Fig. 3 shows a pendulum ring (28), via which the oil from the rotating wobble shaft (15) and the rotating support sleeve (33) finds a way into the connecting rod (29) carrying out a pendulum movement. This pendulum ring (28) has a circumferential collecting groove on its inside, from which the oil reaches the connecting rod oil bore (36) via branch bores (35). The chamfering of the bore (35) on the contact surface of the pendulum ring / connecting rod is so large that even with maximum pendulum deflection, oil still flows smoothly. The ring (28) is secured against rotation by the pins (37), which, however, leave it enough play to compensate for the pendulum movement.

Fig. 4 zeigt einen Querschnitt durch eine Ringraumsperre (Schnitt C-C): Ein zylinderförmiges Drehteil (12) oder eine zylindrische Hülse wird in eine Bohrung gesteckt, die größer und tiefer als der Ringraumquerschnitt ist. Eine Tellerfeder (39) sorgt dafür, daß die vordere Stirnseite dichtet.Fig. 4 shows a cross section through an annular space barrier (section C-C): A cylindrical rotary part (12) or a cylindrical sleeve is inserted into a bore that is larger and deeper than the annular space cross section. A plate spring (39) ensures that the front end seals.
