Description

Beschreibung P 19 09 563q7 Titel: Belastungsabhängige Kompressionsregulierung bei Verbrennungsmotoren ( Ottomotoren ) durch exentrisch gelagerte Kurbelwelle Anwendungs gebiet: Verbrennungsmotoren ( Ottomotoren Aufgabe: Motor mit hohem Kompressionsverhältnis, aber trotzdem mit langer Lebensdauer Lösung: hohes Kompressionsverhältnis nur dann, wenn der Motor stark belastet wird; d.h.: Motor mit veränderlichem Komnressionsverhältnis Ausführung: mit Bezugszeichen zur Skizze I Jedes Lager (1) der Kurbelwelle (2) des Motors sitzt jeweils in der exzentrischen Bohrung eines drehbaren Lagerschildes (3). Durch Drehen der Lagerschilde kann man also den Abstand zwischen Zylinderkopf und Kurbelwelle verändern, d.h. man kann das Kompressionsverhältnis des Motors regeln.Description P 19 09 563q7 Title: Load-dependent compression regulation in combustion engines (Otto engines) by eccentrically mounted crankshaft application area: internal combustion engines (Otto engines task: engine with high compression ratio, but still with a long service life Solution: high compression ratio only if when the engine is heavily loaded; i.e .: engine with variable compression ratio Design: with reference number to sketch I Each bearing (1) of the crankshaft (2) of the The motor sits in the eccentric bore of a rotatable end shield (3). By turning the end shields you can adjust the distance between the cylinder head and change the crankshaft, i.e. you can regulate the compression ratio of the engine.

vorteil: rotoren mit belastungsabhängiger Kompressionsregulierung können bei verhältnismäßig kleinem Hubraum Spitzenleistungen abgeben, andererseits aber bei normaler Belastung auch mit normalem KompressionsverhäLtnis arbeiten und deshalb eine große Lebensdauer erreichen.advantage: rotors with load-dependent compression regulation can deliver top performance with a relatively small displacement, on the other hand but also work with normal compression ratio under normal load and therefore achieve a long service life.

Ausgestaltung: mit Bezugszeichen zur Skizze II Drehung der exzentrischen Lagerschilde Die Welle (1) vom Motor zum Getriebe ( oder die Kardanwelle des Autos ) ist unterbrochen. Die beiden Wellenteile sind durch eine Spiralfeder (2) oder einen Torsiosstab miteinander verbunden. Die Drehung der beiden Wellenteile wird auf ein Differentialgetriebe übertragen, welches 80 angewandt wird, daß bei Gleichlauf der beiden Wellenteile seine dritte freie Welle (5) stillsteht.Design: with reference number to sketch II rotation of the eccentric End shields The shaft (1) from the engine to the gearbox (or the cardan shaft of the car ) is interrupted. The two parts of the shaft are supported by a spiral spring (2) or a torsion bar connected to each other. The rotation of the two shaft parts will transmitted to a differential gear, which is applied 80 that with synchronism of the two shaft parts its third free shaft (5) stands still.

( Das Übersetzungsverhältnis der Drehungsübertragung auf das Differentialgetriebe muß so gewählt werden, daß Had (3) doppelt so schnell läuft wie Rad (4).(The gear ratio of the rotation transmission to the differential gear must be chosen so that Had (3) runs twice as fast as wheel (4).

Wird der Motor belastet, so verdrehen sich die beiden Teile der unterbrochenen Welle (1) gegeneinander um einen Fortsetzung der Beschreibung P 19 Os 563.7 bestimmten Betrag, der von der Belastung und der Stärke der Spiralfeder ( oder des Torsionsstabes ) abhängig ist.If the engine is loaded, the two parts of the interrupted one twist Shaft (1) against each other by one Continuation of the description P 19 Os 563.7 certain amount that depends on the load and strength of the spiral spring (or the torsion bar) is dependent.

Die freie Welle (5) des Differentialgetriebes dreht sich ebenfalls um diesen Betrag. Diese Drehung kann man ausnützen, um die Lagerschilde der Kurbelwelle zu bewegen ( mittels Zahnrädern oder, wie in der Skizze, durch einen Exzenter (6) und eine Schubstange ( Skizze I 4 ) ).The free shaft (5) of the differential gear also rotates by this amount. This rotation can be used to adjust the end shields of the crankshaft to move (by means of gears or, as in the sketch, by an eccentric (6) and a push rod (sketch I 4)).

So kann der Motor selbsttätig sein Kompressionsverhältnis der Belastung anpassen.So the engine can automatically adjust its compression ratio of the load adjust.

Patentansprüche P 19 O9 563.7Patent claims P 19 O9 563.7 Oberbegriff: 1. Belastungsabhsngige Kompressionsregulierung bei Verbrennungsmotoren ( Ottomotoren ), Kennzeichnender Teil : dadurch gekennzeichnet, daß die Lager der Kurbelwelle ihrerseits wieder in der exzentrischen Bohrung des jeweils zugehörigen drehbaren Lagerschildes sitzen, wodurch erreicht wird, daß der Abstand zwischen Kurbelwelle und Zylinderkopf durch Drehen der Lagerschilde verändert werden karin. Generic term: 1. Load-dependent compression regulation in internal combustion engines (Otto engines), characterizing part: characterized in that the bearings of the Crankshaft in turn back in the eccentric bore of the respective associated rotatable bearing plate, whereby it is achieved that the distance between The crankshaft and cylinder head can be changed by turning the end shields. 2, Oberbegriff des Unteranspruchs: 2. Erweiterung zu Anspruch 1., wodurch die Kompressionsregulierung erst Belastungsabhängig wird, Kennz. Teil des Unteranspruchs: dadurch gekennzeichnet, daß die Welle, die die Kraft vom Motor zum Getriebe überträgt, unterbrochen ist und durch eine Spiralfeder oder einen Torsionsstab verbunden wird. Die bei Belastung auftretende Verdrehung der beiden Wellenteile gegeneinander wird, durch besondere Anwendung des Differentialgetriebes, ausgenützt, um die exzentrischen Lagerschilde zu drehen.2, preamble of the sub-claim: 2nd extension to claim 1., whereby the compression regulation only becomes load-dependent, code part of the Subclaim: characterized in that the shaft that the power from the engine to Transmission transmits, is interrupted and by a spiral spring or a torsion bar is connected. The twisting of the two shaft parts that occurs under load is exploited against each other, through special use of the differential gear, to rotate the eccentric end shields.
