Description
Die Erfindung betrifft einen Verbrennungsmotor, der eine Blockiereinrichtung für eine Kurbelwelle aufweist, wobei die Blockiereinrichtung bei einem Auslaufen des Verbrennungsmotors mit der Kurbelwelle in Eingriff gebracht wird, wobei die Blockiereinrichtung ein Eingriffselement und ein starres Halteelemente aufweist, wobei das Eingriffselement dem Halteelement bewegbar zugeordnet ist, so daß das Eingriffselement mit einem der Kurbelwelle zugeordneten Gegeneingriffselement bei einer letzten Kurbelwellenumdrehung derart verbindbar ist, daß die Kurbelwelle in ihrer Ruhestellung in einer vorbestimmten Position einstellbar ist.The invention relates to an internal combustion engine having a blocking device for a crankshaft, wherein the blocking device is brought into engagement with the crankshaft when the internal combustion engine is running out, the blocking device having an engagement element and a rigid retaining element, wherein the engagement element is movably associated with the retaining element, so that the engagement element with a crankshaft associated counter-engagement element in a last crankshaft revolution is connectable such that the crankshaft is adjustable in its rest position in a predetermined position.
Zur Verbesserung der Kraftstoffausnutzung in Fahrzeugen mit Verbrennungsmotor wird dieser häufig anstelle im Leerlauf betrieben zu werden vollständig abgestellt, wenn keine Antriebsleistung benötigt wird. Der Verbrennungsmotor muß dann neu angelassen werden, wenn seine Leistung wieder benötigt wird. Für das Anlassen weisen herkömmliche Verbrennungsmotoren spezielle Einrichtungen, wie etwa einen Anlassermotor oder einen als Motor einsetzbaren Generator, einen so genannten Startergenerator auf. Hierbei handelt es sich um verhältnismäßig große und kostenaufwendige Einrichtungen, da für das Anlassen des Verbrennungsmotors eine hohe elektrische Leistung erforderlich ist.To improve fuel economy in internal combustion engine vehicles, it is often shut down instead of idling when no drive power is needed. The internal combustion engine must then be restarted when its power is needed again. For starting, conventional internal combustion engines have special devices, such as a starter motor or a generator that can be used as a motor, a so-called starter generator. These are relatively large and expensive facilities, since a high electrical power is required for starting the engine.
Darüber hinaus ist es bekannt, einen Verbrennungsmotor durch Auslösen einer Verbrennung anzulassen. Dies ist insbesondere bei Verbrennungsmotoren mit Funkenzündung und Direkteinspritzung möglich. Der direkt in eine Brennkammer eingespritzte Kraftstoff wird dabei durch einen Funken gezündet, und die anschließende Verbrennung des Luft-Kraftstoff-Gemisches bewegt einen Kolben und startet den Verbrennungsmotor, ohne daß die Kurbelwelle durch eine zusätzliche Anlaßereinrichtung bewegt werden müßte. Ein derartiges direktes Anlassen des Motors erfordert jedoch bestimmte Randbedingungen, um erfolgreich durchgeführt werden zu können. Insbesondere ist es erforderlich bzw. vorteilhaft, wenn die Kurbelwelle zu Beginn des Anlassens in oder nahe einer bestimmten Position steht. So sollte sich mindestens ein Kolben eines Zylinders des Verbrennungsmotors in einer Position befinden, in der ein Einspritzen von Kraftstoff und anschließendes Zünden des entstandenen Luft-Kraftstoffgemisches tatsächlich zu einer Bewegung des in dem Zylinder befindlichen Kolbens führt. Bei einem Viertaktverbrennungsmotor müßte der Kolben sich also im Expansions- oder Arbeitstakt befinden, wobei ein mindestens ein zugehöriges Auslaßgaswechselventil noch nicht geöffnet sein darf. Dies kann beispielsweise in einer Position von ca. 90° Kurbelwinkel nach oberem Totpunkt (OT) sein. Dies ist bei herkömmlichen Verbrennungsmotoren in der Regel nicht gewährleistet, da die Kurbelwelle nach dem Abstellen und Auslaufen des Verbrennungsmotors in zufälligen Positionen stehen bleibt.Moreover, it is known to start an internal combustion engine by triggering combustion. This is possible in particular with internal combustion engines with spark ignition and direct injection. The injected directly into a combustion chamber fuel is thereby ignited by a spark, and the subsequent combustion of the air-fuel mixture moves a piston and starts the engine, without the crankshaft would have to be moved by an additional starter device. However, such direct starting of the engine requires certain boundary conditions in order to be able to be carried out successfully. In particular, it is necessary or advantageous if the crankshaft is in or near a certain position at the start of cranking. Thus, at least one piston of a cylinder of the internal combustion engine should be in a position in which an injection of fuel and subsequent Igniting the resulting air-fuel mixture actually leads to a movement of the piston located in the cylinder. In a four-stroke internal combustion engine, the piston would therefore have to be in the expansion or power stroke, with at least one associated outlet gas exchange valve not yet allowed to be opened. This can for example be in a position of about 90 ° crank angle to top dead center (TDC). This is conventional Internal combustion engines usually not guaranteed because the crankshaft stops after stopping and running of the engine in random positions.

Die Blockiereinrichtung ist derart ausgestaltet, daß eine Drehbewegung der Kurbelwelle in einer und/oder zwei Richtungen blockiert wird. Die Blockiereinrichtung kann beispielsweise mittels Bolzen und/oder Klinkenrädem bzw. Sperrrädem realisiert werden, die in ein zugeordnetes Zahnrad der Kurbelwelle eingreifen. Altemativ kann eine solche Blockiereinrichtung mittels einer Reibvorrichtung vorgesehen sein, die mit der Kurbelwelle zusammenwirkt. Diese Ausgestaltung hat sich in der Praxis bewährt, allerdings ist zum Starten des Verbrennungsmotors weiterhin eine, wenn auch eine kleinere, Startereinrichtung vorzusehen.An unreleased disclosure going back to the Applicant relates to a blocking device for the crankshaft of an internal combustion engine. The blocking device is designed such that a rotational movement of the crankshaft is blocked in one and / or two directions. The blocking device can be realized for example by means of bolts and / or ratchet wheels or locking wheels, which engage in an associated gear of the crankshaft. Alternatively, such a blocking device may be provided by means of a friction device, which cooperates with the crankshaft. This embodiment has proven itself in practice, however, to start the engine continues to provide one, albeit a smaller, starter device.
Von daher liegt der Erfindung die Aufgabe zugrunde, einen Verbrennungsmotor der eingangs genannten Art mit einer verbesserten Blockiereinrichtung für eine Kurbelwelle zur Verfügung zu stellen, welche ein kontrolliertes Abstellen des Verbrennungsmotors mit einfachen Mitteln erreicht.Therefore, the invention has the object to provide an internal combustion engine of the type mentioned with an improved blocking device for a crankshaft available, which achieves a controlled shutdown of the engine with simple means.
Erfindungsgemäß wird diese Aufgabe durch einen Verbrennungsmotor mit den Merkmalen des Anspruchs 1 gelöst.According to the invention this object is achieved by an internal combustion engine with the features of
Mit der erfindungsgemäßen Blockiereinrichtung wird erreicht, daß sich zumindest ein Kolben des Verbrennungsmotors in einer bestimmten, günstigen Konfiguration befinden, wobei diese bestimmte Konfiguration einem bzw. einer bestimmten Winkelbereich bzw. -position der Kurbelwelle entspricht. Damit wird eine verbesserte Blockiereinrichtung zur Verfügung gestellt, mit der es möglich ist, ein starterloses direktes Anlassen des Verbrennungsmotors, beispielsweise durch Kraftstoffzündungen, zu bewirken.With the blocking device according to the invention it is achieved that at least one piston of the internal combustion engine are in a certain, favorable configuration, this specific configuration corresponding to one or a certain angular range or position of the crankshaft. Thus, an improved blocking device is provided with which it is possible to effect a starterless direct starting of the internal combustion engine, for example by fuel ignitions.
Um einen kraftformschlüssigen Eingriff des Eingriffselementes mit dem Gegeneingriffselement zu erreichen, ist es günstig im Sinne der Erfindung, wenn das Eingriffselement mit einer verzahnten Eingriffsseite ausgestaltet ist, das mit dem Gegeneingriffselement in einer radialen Richtung bezogen auf die Kurbelwelle in Eingriff gebracht wird, wobei das Gegeneingriffselement als zur verzahnten Eingriffsseite komplementärer Zahnkranz ausgestaltet ist. Das Eingriffselement kann im Querschnitt gesehen vorzugsweise viereckig ausgestaltet sein. Der Zahnkranz ist in einer bevorzugten Ausführung direkt auf der Kurbelwelle angeordnet, kann aber auch auf einer mit der Kurbelwelle verbundenen Welle angeordnet sein. Dies kann z.B. auch ein bereits vorhandener Starterzahnkranz sein. Das Eingriffselement blockiert die Kurbelwelle während ihrer letzten Umdrehung in der vorbestimmten Position, welche dem gewünschten Kurbelwinkelbereich entspricht, wobei das Eingriffselement die Kurbelwelle in einer festen Position relativ zu einem Kurbelgehäuse abrupt blockiert, wenn das Eingriffselement in das Gegeneingriffselement eingerückt wird. Es liegt durchaus im Sinne der Erfindung, daß das Eingriffselement hydraulisch, mechanisch, pneumatisch und/oder elektrisch betätigt wird.In order to achieve a form-locking engagement of the engagement element with the counter-engagement element, it is favorable in the context of the invention, when the engagement element is configured with a toothed engagement side, which is brought into engagement with the counter-engagement element in a radial direction relative to the crankshaft, wherein the counter-engagement element designed as a toothed engagement side complementary sprocket. The engagement element can be configured preferably quadrangular in cross section. The sprocket is arranged in a preferred embodiment directly on the crankshaft, but may also be arranged on a shaft connected to the crankshaft. This can also be, for example, an existing starter tooth ring. The engagement member blocks the crankshaft during its last revolution in the predetermined position corresponding to the desired crank angle range, the engagement element positioning the crankshaft in a fixed position relative to a crankshaft Crankcase abruptly blocked when the engagement element is engaged in the counter-engagement element. It is well within the meaning of the invention that the engagement element is hydraulically, mechanically, pneumatically and / or electrically actuated.
Zweckmäßig im Sinne der Erfindung ist, wenn das Eingriffsmittel in einer Umfangsrichtung bezogen auf einen Außenumfang der Kurbelwelle bzw. des Gegeneingriffselementes bewegbar mit dem Halteelement verbunden ist, wobei das Halteelement eine entsprechende Führungseinrichtung für das Eingriffselement aufweist. Diese Führungseinrichtung kann beispielsweise eine Kulissenführung sein, die in das Halteelement eingebracht ist. Damit kann das Eingriffselement mit der Kurbelwelle in deren Umfangsrichtung mitgenommen werden, bis das Eingriffselement ein Anschlagende des Halteelementes erreicht. Von daher ist es sinnvoll im Sinne der Erfindung, wenn das Halteelement in Umfangsrichtung zumindest ein Anschlagende aufweist. Bevorzugterweise ist das Anschlagende derart angeordnet, daß die Kurbelwelle in ihrer Ruhestellung in der vorbestimmten Position einstellbar ist, wobei die vorbestimmte Position eben der erforderliche Kurbelwinkelbereich ist, der notwendig ist, um ein starterloses, direktes Anlassen des Verbrennungsmotors zu gewährleisten, wobei sich der zumindest eine Kolben in einer hierzu günstigen Position befindet.It is expedient for the purposes of the invention, when the engagement means in a circumferential direction with respect to an outer circumference of the crankshaft and the counter-engagement element is movably connected to the holding element, wherein the holding element has a corresponding guide means for the engagement element. This guide device may for example be a slotted guide, which is introduced into the holding element. Thus, the engagement element can be taken with the crankshaft in the circumferential direction until the engagement element reaches a stop end of the holding element. Therefore, it makes sense in the context of the invention, when the holding element has at least one stop end in the circumferential direction. Preferably, the stop end is arranged such that the crankshaft is adjustable in its rest position in the predetermined position, wherein the predetermined position is just the required crank angle range, which is necessary to ensure a starterless, direct starting of the internal combustion engine, wherein the at least one Piston is in a favorable position.
Um ein sanftes Abbremsen der Kurbelwelle während ihrer letzten Umdrehung zu erreichen, ist es günstig, wenn das Eingriffselement an zumindest einem Kraftspeicherelement befestigt ist, der anderendig mit dem Halteelement verbunden ist. In einer bevorzugten Ausgestaltung ist das Kraftspeicher element als Feder ausgestaltet, wobei das Kraftspeicherelement nach dem Einrücken bzw. nach dem Eingriff des Eingriffselementes in das Gegeneingriffselement zunächst in Umfangsrichtung gespannt wird, bis das Eingriffselement an dem Anschlagende anschlägt, um dann entsprechend einem Gleichgewicht der Federkraft in die vorbestimmte Position zurückgeholt zu werden. Hierbei nimmt das Kraftspeicherelement das eingerückte Eingriffsmittel und somit die Kurbelwelle mit. Selbstverständlich ist es möglich, im Querschnitt gesehen beidseitig des Eingriffselementes jeweils ein oder mehrere Kraftspeicherelemente vorzusehen, so daß das Eingriffselement in zwei oder mehr Federn eingebettet ist. Aufgrund der flexiblen Lagerung der Blockiereinrichtung, insbesondere der flexiblen Ausdehnung der Federn, wird ein sehr sanfter Eingriffsprozeß zur Verfügung gestellt. Nach dem Eingriff des Eingriffselementes in das Gegeneingriffselement werden die Federn während der Kurbelwellenumdrehung gespannt, wobei die Kurbelwelle anschließend in der vorbestimmten Position gelagert wird, was durch das Kräftegleichgewicht der Kraftspeicheretemente hervorgerufen wird.In order to achieve a smooth braking of the crankshaft during its last revolution, it is favorable if the engagement element is fastened to at least one force storage element, which is otherwise connected to the holding element. In a preferred embodiment, the energy storage element is designed as a spring, wherein the force storage element is first tensioned in the circumferential direction after engagement or after the engagement of the engagement element in the counter-engagement element until the engagement element strikes against the stop end, then according to a balance of the spring force in the predetermined position to be retrieved. Here, the energy storage element takes the engaged engagement means and thus the crankshaft. Of course, it is possible, seen in cross-section on both sides of the engagement element to provide one or more force storage elements, so that the engagement element is embedded in two or more springs. Due to the flexible storage of the blocking device, in particular the flexible extension of the springs, a very gentle engagement process is provided. After the engagement of the engagement element in the counter-engagement element, the springs are tensioned during the crankshaft revolution, wherein the crankshaft is then stored in the predetermined position, which is caused by the force equilibrium of the power storage elements.
In einer weiteren Ausgestaltung der Erfindung ist zweckmäßig vorgesehen, daß dem Halteelement ein Positionierring zugeordnet ist, der über eine Positioniervorrichtung in Umfangsrichtung bewegbar ist, wobei der Positionierring ein Anschlagende aufweist. Hierbei kann der Positionierring über die Positioniervorrichtung mit dem Halteelement verbunden sein, so daß der Positionierring in Umfangsrichtung verschiebbar ist. Greift nun das Eingriffselement in das Gegeneingriffselement ein und schlägt an dem Anschlagende an, wird die Kurbelwelle durch Einwirkung des Anschlagendes des Positionierrings über die umfanggemäße Verschiebung des Positionierrings in die vorbestimmte Position verstellt. Bei dieser Ausgestaltung dreht sich das Eingriffselement mit der Kurbelwellenumdrehung, bis das Eingriffselement an dem Anschlagende anschlägt, wobei die Kurbelwelle selbstverständlich auch automatisch anhalten kann, bevor das Eingriffselement das Anschlagende erreicht. Vorteilhaft bei dieser Ausgestaltung ist, daß das Anschlagende in einer optimalen Position angeordnet werden kann, um ein sanftes Auslaufen des Verbrennungsmotors zu gewährleisten. Nachdem die Kurbelwelle sich nicht mehr dreht, kann das Eingriffselement über die Einwirkung des Positionierringes bzw. der Positioniervorrichtung derart eingestellt werden, daß die Kurbelwelle in der vorbestimmten Position gelagert ist. Selbstverständlich kann die Positioniervorrichtung elektrisch, hydraulisch, mechanisch oder pneumatisch betätigt werden. Selbstverständlich kann bei dieser Ausführungsform auch vorgesehen sein, daß das Eingriffselement mit zumindest einem Kraftspeicher versehen ist, der anderendig mit dem Halteelement verbunden ist.In a further embodiment of the invention is advantageously provided that the retaining element is associated with a positioning ring which is movable via a positioning device in the circumferential direction, wherein the positioning ring has a stop end. Here, the positioning ring can be connected via the positioning device with the holding element, so that the positioning ring is displaceable in the circumferential direction. If the engagement element then engages in the counter-engagement element and abuts against the abutment end, the crankshaft is adjusted to the predetermined position by the action of the abutment end of the positioning ring via the circumferential displacement of the positioning ring. In this embodiment, the engagement member rotates with the crankshaft revolution until the engagement member abuts the abutment end, the crankshaft can of course stop automatically before the engagement member reaches the abutment end. An advantage of this design is that the abutment end can be arranged in an optimal position to ensure a smooth leakage of the internal combustion engine. After the crankshaft no longer rotates, the engagement member can be adjusted via the action of the positioning ring or the positioning device such that the crankshaft is mounted in the predetermined position. Of course, the positioning device can be operated electrically, hydraulically, mechanically or pneumatically. Of course, it can also be provided in this embodiment that the engagement element is provided with at least one energy storage, which is connected at the other end to the holding element.

Bei dieser Ausgestaltung der Erfindung ist das Eingriffselement relativ zum Kurbelgehäuse in einer festen Position angeordnet und greift in dieser festen Position in das Gegeneingriffselement ein. Somit ist die Kurbelwelle wieder abrupt gestoppt, wenn das Eingriffselement in das Gegeneingriffselement eingreift. Durch die Positioniervorrichtung ist es möglich, daß eine optimale Verriegelungs- bzw. Einrückposition gewählt werden kann, um ein sanftes Auslaufen des Verbrennungsmotors zu gewährleisten. Nachdem die Kurbelwelle gestoppt ist, wird diese durch das in Eingriff stehende Eingriffselement über das Gegeneingriffselement in die vorbestimmte Position bewegt, so daß ein starterloses, direktes Anlassen des Verbrennungsmotors möglich ist.In a further advantageous embodiment of the invention, it is expedient if the retaining element is associated with a positioning ring, in which the engagement element is integrated, wherein the positioning ring is movable via a positioning device in the circumferential direction. In this embodiment of the invention that is Engagement element disposed relative to the crankcase in a fixed position and engages in this fixed position in the counter-engagement element. Thus, the crankshaft is abruptly stopped again when the engagement element engages the counter-engagement element. By the positioning device, it is possible that an optimal locking or engagement position can be selected to ensure a smooth leakage of the internal combustion engine. After the crankshaft is stopped, it is moved by the engaging engagement member via the counter-engagement member in the predetermined position, so that a starterless, direct starting of the engine is possible.
Selbstverständlich liegt es im Sinne der Erfindung, wenn das Eingriffselement bzw. das in dem Positionierring integrierte Eingriffselement über eine zentrale Motorsteuereinheit angesteuert wird, welche auch das Auslaufen des Verbrennungsmotors steuert, um die geeignete, vorbestimmte Position der Kurbelwelle zu erreichen, um ein direktes, starterloses Anlassen des Verbrennungsmotors zu erreichen, so daß sich der zumindest eine Kolben in einer hierzu günstigen Position befindet.Of course, it is within the meaning of the invention, when the engagement element or in the positioning integrated engagement element is controlled by a central engine control unit, which also controls the leakage of the engine to reach the appropriate predetermined position of the crankshaft to a direct, starterless Starting the internal combustion engine to achieve so that the at least one piston is in a favorable position for this purpose.
