Definitions

  • the swash plate 20 of the invention has one or more of the following characteristics :
  • the envelope 7 is formed by two shells 7E1,7E2 which are attached together for forming inner chamber for receiving the tube elements, the pistons, the swash plates and the drive shaft, as well as for forming channels 7C for a cooling liquid, and channels for the passage of air into the combustion chambers or for the exhaust of combustion gases.
  • PP engines suffer from wear of the swash plate owing to the forces applied between the joints which translate the lateral movement of the pistons into rotational movement by the drive shaft. Improvements to the design of the swash plate by the present inventor have surprisingly lead to a better distribution of forces within the swash plate bearings, which improvements do not require more heavily engineered components, or more substantial bearings.

Claims (8)

  1. Taumeleinheit für einen Kraftstoffmotor mit einer Antriebswelle (29), die sich durch eine Hülle (7) mit einer Öffnung erstreckt, durch die sich die Antriebswelle (29) erstreckt, wobei die Taumeleinheit eine mittige Anordnung (48) umfasst, die einem Ring (47) zugeordnet ist, der mit mindestens zwei Kupplungselementen (19) zur Übertragung von Kolbenbewegungen versehen ist, wobei die mittige Anordnung (48) zwei Teile (48A, 48B) umfasst, die aneinander befestigt sind, wobei die Teile jeweils ein Loch aufweisen, wobei die Löcher, wenn die beiden Teile montiert sind, einen Durchgang bilden, durch den die Antriebswelle (29) hindurchgeht,
    In der das erste Teil (48A), das ein einziges Teil bildet, Folgendes umfasst:
    ein im Wesentlichen zylindrisches Element (48A1), das angepasst ist, um in einem zentralen Loch (47H) des Rings (47) gelagert zu werden, wobei das zylindrische Element eine Achse aufweist, die der Mittelachse des mittigen Lochs des Rings entspricht, wobei das zylindrische Element ein Loch aufweist, das für den Durchgang eines Teils der Antriebswelle angepasst ist, wobei sich das zylindrische Element (48A1) zwischen einem ersten freien Ende und einem zweiten Ende erstreckt, wobei das erste Ende des zylindrischen Elements, das in dem mittigen Loch (47H) des Rings (47) gelagert ist, so angepasst ist, dass es sich außerhalb des zentralen Lochs (47H) des Rings (47) erstreckt,
    ein im Wesentlichen kreisförmiges Plattenelement (48A2), das sich zumindest teilweise außerhalb des mittigen Lochs (47H) des Rings (47) erstreckt, wobei das Plattenelement (48A2) eine Fläche (48F1) aufweist, die über ein zwischengeschaltetes Lager (49) mit einer Außenfläche des Rings (47) in Kontakt steht, und
    ein Zwischenelement (48A4), das sich auf der Fläche des im Wesentlichen kreisförmigen Plattenelements erstreckt, die nicht auf das im Wesentlichen zylindrische Element (48A1) gerichtet ist, wobei das Zwischenelement Rippen aufweist,
    in der das zweite Teil (48B), das ein einziges Teil bildet, Folgendes umfasst:
    ein im Wesentlichen kreisförmiges Plattenelement (48B2), das sich außerhalb des mittigen Loches (47H) des Rings (47) erstreckt, wobei das Plattenelement (48B2) eine Fläche (48F2) aufweist, die über ein zwischengeschaltetes Lager (49) mit einer Außenfläche des Rings (47) in Kontakt steht,
    ein vorstehendes Element (48B3) mit einem Loch, das an den Durchgang eines Abschnitts der Antriebswelle (29) angepasst ist, wobei der Durchgang für die Antriebswelle (29), der durch die Löcher des ersten Abschnitts (48A) und des zweiten Abschnitts (48B) gebildet wird, einen Winkel zwischen 10° und 50° mit der Achse des zylindrischen Elements (48A1) bildet, und
    in dem die Elemente des ersten und zweiten Teils so angepasst sind, dass der Schwerpunkt der Taumeleinheit auf der Durchgangsachse für die Antriebswelle liegt,
    in dem der erste Teil (48A) ferner ein rohrförmiges vorstehendes Element (48A3) umfasst, das an dem Zwischenelement (48A4) befestigt ist, wobei das rohrförmige vorstehende Element (48A3) ein Loch aufweist, das für den Durchgang eines Abschnitts der Antriebswelle (29) angepasst ist, in dem das vorstehende Element (48A3) ein freies Ende mit einer Fläche aufweist, die sich in einer Ebene senkrecht zur Antriebswelle (29) erstreckt, wobei das rohrförmige vorstehende Element (48A3) eine Länge zwischen 2 und 10 cm aufweist, wobei das vorstehende Element (48A3) angepasst ist, um sich in die Öffnung der Aussparung des Motorgehäuses (7) unter Zwischenschaltung eines Lagers zu erstrecken, das in die Öffnung der Aussparung des Gehäuses (7) einzusetzen ist, dadurch gekennzeichnet, dass das Lager (20B) in Kontakt mit der Außenfläche des vorstehenden Elements (48A3) steht.
  2. Taumeleinheit nach Anspruch 1, dadurch gekennzeichnet, dass die Elemente des ersten und zweiten Teils so angepasst sind, dass der Schwerpunkt der Taumeleinheit am Schnittpunkt der Achse des Loches für die Antriebswelle (29) mit der Achse des mittigen Loches des Rings (47) liegt.
  3. Taumeleinheit nach einem der vorstehenden Ansprüche, dadurch gekennzeichnet, dass das einzige Teil des ersten Abschnitts durch folgende Elemente des ersten Abschnitts gebildet wird:
    Im Wesentliches zylindrisches Element (48A1),
    Im Wesentlichen kreisförmige Platte (48A2),
    Vorstehendes rohrförmiges Teil (48A3) und
    Zwischenelement (48A4).
  4. Taumeleinheit nach einem der vorstehenden Ansprüche, dadurch gekennzeichnet, dass das einzige Teil des zweiten Abschnitts durch folgende Elemente des zweiten Abschnitts gebildet wird:
    Das im Wesentlichen kreisförmige Plattenelement (48B2), das sich zumindest teilweise aus dem mittigen Loch (47H) des Rings (47) heraus erstreckt, und
    Ein vorstehendes Element (48B3) mit einem Loch, das für den Durchgang eines Abschnitts der Antriebswelle (29) ausgelegt ist, wobei das Loch eine Achse aufweist, die einen Winkel zur Achse des mittigen Lochs des Rings (47) bildet.
  5. Taumeleinheit nach einem der vorstehenden Ansprüche, dadurch gekennzeichnet, dass die Kupplungselemente jeweils mittels eines Radialarms am Ring (47) befestigt sind, wobei sich die Achsen der Radialarme an einem Punkt kreuzen, der sich auf der Achse des mittigen Lochs (47H) des Rings (47) befindet.
  6. Taumeleinheit nach Anspruch 5, dadurch gekennzeichnet, dass die Kupplungselemente jeweils mittels eines Radialarms am Ring (47) befestigt sind, wobei sich die Achsen der Radialarme an einem Punkt kreuzen, der sich auf der Achse des Lochs des rohrförmigen Vorsprungs befindet.
  7. Kraftstoffmotor mit mindestens einer Taumeleinheit nach einem der vorstehenden Ansprüche und mit mindestens einem Gehäuse (7) mit einer Aussparung zur Aufnahme des vorstehenden Elements (48A3) der Taumeleinheit mit zwischengeschaltetem Lager (20B).
