Description
Die Erfindung betrifft ein Antriebssystem mit einem Antriebsmotor und einem Schaltgetriebe, wobei der Antriebsmotor und das Schaltgetriebe über ein Umlaufgetriebe miteinander verbunden sind.The invention relates to a drive system with a drive motor and a transmission, wherein the drive motor and the transmission are connected to each other via a planetary gear.
Antriebssysteme – bzw. Lastschaltmodule – bei denen eine primäre Energiequelle wie beispielsweise ein Verbrennungsmotor über ein Planeten- oder Umlaufgetriebe mit einem Schaltgetriebe verbunden sind, sind bekannt (
Aus der
Der Erfindung liegt die Aufgabe zugrunde, ein Antriebssystem zu schaffen, welches ausgehend von bekannten Lastschaltmodulen eine Verbesserung hinsichtlich der Energieausnutzung ermöglicht und bei dem die Einsatzmöglichkeiten verbessert sind.The invention has for its object to provide a drive system which, starting from known power shift modules allows an improvement in terms of energy utilization and in which the application possibilities are improved.
Die Erfindung gemäß Anspruch 1 löst diese Aufgabe.The invention according to
Das erfindungsgemäße Antriebssystem weist einen Antriebsmotor und ein Schaltgetriebe auf. Der Antriebsmotor ist beispielsweise als Brennkraftmaschine ausgeführt, wobei dieser über ein Planeten- bzw. Umlaufgetriebe mit dem Schaltgetriebe verbunden ist. Das Umlaufgetriebe weist insgesamt drei Getriebeelemente auf, die üblicherweise als Sonnenrad, Steg und Hohlrad bezeichnet werden. Ein erstes Getriebeelement des Umlaufgetriebes ist dabei mit dem Antriebsmotor gekoppelt, im einfachsten Fall also mit dessen Kurbelwelle verbunden. Ein zweites Getriebeelement ist dagegen mit einer Ausgangswelle eines Schaltgetriebes verbunden, welche in der Regel mit einem Radantrieb permanent drehfest verbunden ist. Das dritte Getriebeelement des Umlaufgetriebes ist dagegen erfindungsgemäß mit einer hydrostatischen Energiespeichervorrichtung verbunden. Die Verbindung mit der Energiespeichervorrichtung erlaubt es, im Falle des Zuführens von Energie in die Energiespeichervorrichtung die Last auf das dritte Getriebeelement zu erhöhen und somit eine Bremswirkung zu erzielen. Damit ergibt sich die gleiche Funktion, die beim bekannten Stand der Technik durch die reibschlüssige Kupplung erzielt wird. Allerdings kann nun die gespeicherte Energie zu einem späteren Zeitpunkt zurückgewonnen werden. Durch die Verbindung des dritten Getriebeelements mit der Energiespeichervorrichtung lässt sich nämlich unter Ausnutzung der gespeicherten Energie umgekehrt auch ein Drehmoment dem Umlaufgetriebe zuführen, welches das von dem Antriebsmotor erzeugte Drehmoment ergänzt.The drive system according to the invention has a drive motor and a manual transmission. The drive motor is designed, for example, as an internal combustion engine, wherein this is connected via a planetary or epicyclic gearbox to the gearbox. The planetary gear has a total of three gear elements, which are commonly referred to as sun gear, web and ring gear. A first gear element of the epicyclic gear is coupled to the drive motor, in the simplest case so connected to the crankshaft. In contrast, a second gear element is connected to an output shaft of a gearbox, which is usually permanently connected in a rotationally fixed manner to a wheel drive. The third transmission element of the planetary gear, however, according to the invention is connected to a hydrostatic energy storage device. The connection with the energy storage device makes it possible, in the case of supplying energy into the energy storage device, to increase the load on the third transmission element and thus to achieve a braking effect. This results in the same function, which is achieved in the prior art by the frictional coupling. However, the stored energy can now be recovered at a later date. By the connection of the third gear element with the energy storage device, in fact, by utilizing the stored energy, a torque can conversely also be supplied to the epicyclic gear which supplements the torque generated by the drive motor.
In den Unteransprüchen sind vorteilhafte Weiterbildungen des erfindungsgemäßen Antriebssystems ausgeführt.In the dependent claims advantageous developments of the drive system according to the invention are carried out.
Insbesondere ist es vorteilhaft, wenn die Energiespeichervorrichtung zumindest eine hydrostatische Maschine und eine damit verbundene Druckspeichereinheit umfasst. Eine solche hydrostatische Maschine in Kombination mit einer Druckspeichereinheit erlaubt es in besonders einfacher Weise, die zurückgewonnene Energie zu speichern und anschließend wieder zu nutzen. Insbesondere ist es vorteilhaft, dass die hydrostatische Maschine sowohl als Pumpe als auch als Motor betrieben werden kann. Solche Maschinen, die ein veränderbares Förder- bzw. Schluckvolumen aufweisen, können zur Realisierung verschiedener Betriebszustände besonders einfach angesteuert werden. Außerdem bauen sie kompakt und erlauben die Anwendung bekannter und etablierter Verstellvorrichtungen.In particular, it is advantageous if the energy storage device comprises at least one hydrostatic machine and an associated pressure storage unit. Such a hydrostatic machine in combination with an accumulator unit makes it possible in a particularly simple manner to store the recovered energy and then reuse it. In particular, it is advantageous that the hydrostatic machine can be operated both as a pump and as a motor. Such machines, which have a variable delivery or intake volume, can be controlled in a particularly simple way for realizing various operating states. In addition, they are compact and allow the use of known and established adjusting devices.
Gemäß einer weiteren Ausführungsform ist es bevorzugt, dass das Antriebssystem weiterhin eine Steuervorrichtung aufweist. Diese Steuervorrichtung ist so eingerichtet, dass die hydrostatische Maschine beim Wechseln von einer Getriebestufe auf eine andere Getriebestufe des Schaltgetriebes abhängig von ihrer durch das gewählte Übersetzungsverhältnis vorgegebener Drehrichtung entweder in einen Pumpbetrieb oder einen Motorbetrieb gebracht wird. Dies wird erreicht, indem die verstellbare hydrostatische Maschine auf ein entsprechendes Fördervolumen bzw. Schluckvolumen eingestellt wird. Besonders einfach ist dies im Falle einer Axialkolbenmaschine in Schrägscheibenbauweise realisierbar. Die Schrägscheibe kann dabei über ihre Neutralstellung hinaus in beide Richtungen geschwenkt werden, so dass die hydrostatische Maschine einen sogenannten Vierquadrantenbetrieb ermöglicht.According to a further embodiment, it is preferred that the drive system further comprises a control device. This control device is arranged so that the hydrostatic machine is brought into either a pumping mode or a motor mode when changing from one gear stage to another gear stage of the gearbox depending on their predetermined by the selected gear ratio direction of rotation. This is achieved by the adjustable hydrostatic machine is set to a corresponding displacement or displacement. This is particularly easy in the case of an axial piston machine in swash plate design feasible. The swash plate can be pivoted beyond its neutral position in both directions, so that the hydrostatic machine allows a so-called four-quadrant operation.
Dabei ist es besonders bevorzugt, wenn die Steuervorrichtung so eingerichtet ist, dass während eines normalen Antriebsbetriebs, bei dem also ein durch den Antriebsmotor erzeugtes Moment über eine eingelegte Getriebestufe des Schaltgetriebes auf die Ausgangswelle übertragen wird, die hydrostatische Maschine auf ein Nullhubvolumen eingestellt wird. Bei diesem Nullhubvolumen befindet sich beispielsweise die oben bereits angegebene Schrägscheibe in Neutralstellung und die hydrostatische Maschine läuft abgesehen von Reibungsverlusten frei mit.It is particularly preferred if the control device is set up so that during a normal drive operation, ie in a torque generated by the drive motor is transmitted to the output shaft via an engaged gear stage of the gearbox, the hydrostatic machine is set to a Nullhubvolumen. With this zero stroke volume, for example, the swash plate already mentioned above is in the neutral position and the hydrostatic machine runs free except for friction losses.
Sofern in dem Speicherelement Druckmittel unter Druck gespeichert ist, kann dieser auch genutzt werden, wenn die Steuervorrichtung gemäß einer besonders bevorzugten Ausführungsform so eingerichtet ist, dass während der momentanen Übertragung von dem Antriebsmotor mittels einer eingelegten Getriebestufe auf die Ausgangswelle des Schaltgetriebes die hydrostatische Maschine auf ein Schluckvolumen zum Zuführen eines zusätzlichen Antriebsmoments eingestellt wird. Damit übernimmt das Umlaufgetriebe die Funktion eines Summiergetriebes, und die für den Antrieb zur Verfügung stehenden Drehmomente addieren sich aus dem durch den Antriebsmotor erzeugten Drehmoment und dem durch die hydrostatische Maschine erzeugten Drehmoment.If pressure medium is stored under pressure in the storage element, this can also be used if the control device is arranged according to a particularly preferred embodiment, that during the current transmission from the drive motor by means of an engaged gear stage on the output shaft of the gearbox, the hydrostatic machine on Suction volume for supplying an additional drive torque is set. Thus, the epicyclic gear takes over the function of a summing gear, and the available torques for the drive add up from the torque generated by the drive motor and the torque generated by the hydrostatic machine.
Eine weitere Möglichkeit zur Energieeinsparung ergibt sich, wenn die in dem Speicher gespeicherte Druckenergie verwendet werden kann, um den Antriebsmotor, der als Brennkraftmaschine ausgestaltet ist, zu starten. Hierzu wird durch die Steuervorrichtung die hydrostatische Maschine in den Motorbetrieb gebracht und auf ein entsprechendes Schluckvolumen gestellt. Aus dem Speicher wird dann Druckmittel über die im Motorbetrieb befindliche hydrostatische Maschine in ein Tankvolumen entspannt, wobei ein Drehmoment durch die hydrostatische Maschine erzeugt wird. Dieses wird zum Starten des Verbrennungsmotors verwendet.A further possibility for energy saving arises when the pressure energy stored in the memory can be used to start the drive motor, which is designed as an internal combustion engine. For this purpose, the hydrostatic machine is brought into engine operation by the control device and set to a corresponding displacement. Pressure medium is then released from the store via the hydrostatic machine located in engine operation into a tank volume, wherein a torque is generated by the hydrostatic machine. This is used to start the internal combustion engine.
Weiterhin ist es bevorzugt, wenn die Steuervorrichtung so eingerichtet ist, dass sie während des Schiebebetriebs des Antriebssystems den Druckspeicher wieder mit Druckmittel füllt. Hierzu wird die hydrostatische Maschine auf ein Fördervolumen eingestellt, so dass die sich dann im Pumpbetrieb befindliche hydrostatische Maschine Druckmittel aus einem Tankvolumen in den Druckspeicher unter Erhöhung des dort herrschenden Drucks fördert.Furthermore, it is preferred if the control device is set up so that it fills the pressure accumulator again with pressure medium during the pushing operation of the drive system. For this purpose, the hydrostatic machine is set to a delivery volume, so that the then located in pumping hydrostatic machine pressure medium from a tank volume in the accumulator promotes increasing the prevailing pressure there.
Weiterhin ist es vorteilhaft, wenn die Energiespeichervorrichtung eine Kupplung aufweist. Mithilfe dieser Kupplung ist dann die hydrostatische Maschine von dem Umlaufgetriebe ganz abkoppelbar, so dass auch die Reibungsverluste der hydrostatischen Maschine reduziert werden können.Furthermore, it is advantageous if the energy storage device has a coupling. With the aid of this coupling, the hydrostatic machine can then be completely decoupled from the planetary gear, so that the friction losses of the hydrostatic machine can also be reduced.
Ein besonders einfacher konstruktiver Aufbau ergibt sich dann, wenn als drittes Getriebeelement das Hohlrad des Umlaufgetriebes vorgesehen ist.A particularly simple constructive structure results when the ring gear of the epicyclic gear is provided as the third gear element.
Vorzugsweise ist das erste Getriebeelement das Sonnenrad des Umlaufgetriebes, wobei dieses Sonnenrad mittels einer Kupplung mit der Eingangsrille des Schaltgetriebes verbunden ist. Das Schaltgetriebe kann somit von der Kurbelwelle des Verbrennungsmotors abgekuppelt werden, ohne dass eine eingelegte Gangstufe herausgenommen werden muss. Dementsprechend ist besonders bevorzugt weiterhin der Steg als zweites Getriebeelement des Umlaufgetriebes ausgeführt.Preferably, the first gear member is the sun gear of the epicyclic gear, said sun gear is connected by means of a clutch to the input groove of the gearbox. The manual transmission can thus be disconnected from the crankshaft of the internal combustion engine, without an inserted gear ratio must be taken out. Accordingly, the web is particularly preferably designed as a second transmission element of the epicyclic gearbox.
Weiterhin ist es bevorzugt, dass eine Druckbegrenzungseinrichtung für eine Langsamfahrt oder einen langdauernden Bremsvorgang den Druck eines Druckmittels durch gesteuertes kontinuierliches Abführen des Druckmittels begrenzt, wenn das Druckmittel im hydrostatischen Druckspeicher bzw. seiner Zuleitung einen festgelegten Druckwert erreicht. Die Druckbegrenzungseinrichtung ist zwischen hydrostatischer Maschine und hydrostatischem Druckspeichereinheit vorzusehen und für dauerfesten Betrieb auszulegen. Sie ermöglicht es, die hydrostatische Maschine weiter im Pumpenbetrieb zu betreiben, wenn der hydrostatische Druckspeicher voll ist und eine weitere Erhöhung des Drucks in dem hydrostatischen Druckspeicher nicht zulässig ist. Die Druckbegrenzungseinrichtung ist sinnvoll als dauerfestes Druckbegrenzungsventil ausgeführt, das Druckmittel in ein Tankvolumen entspannt. Die Druckbegrenzungseinrichtung ist vorzugsweise zusätzlich zu einem als Sicherheitseinrichtung dienenden Druckbegrenzungsventil vorhanden, welches in der Regel zwar die Absicherung gegen hohe Drücke ermöglicht, aber nicht zum hydraulischen Bremsen geeignet ist. Diese Ausführung ermöglicht ein kontinuierliches Langsamfahren über ein langen Zeitraum oder eine Zugkraftunterstützung auch bei vollem hydrostatischem Druckspeicher.Furthermore, it is preferred that a pressure limiting device for a slow speed or a long braking operation limits the pressure of a pressure medium by controlled continuous discharge of the pressure medium when the pressure medium in the hydrostatic pressure accumulator or its supply line reaches a predetermined pressure value. The pressure limiting device is to be provided between the hydrostatic machine and the hydrostatic pressure storage unit and designed for long-term operation. It allows the hydrostatic machine to continue to operate in pump mode when the hydrostatic accumulator is full and further increase in pressure in the hydrostatic accumulator is not permitted. The pressure limiting device is useful designed as a permanent pressure relief valve that relaxes pressure medium in a tank volume. The pressure limiting device is preferably present in addition to serving as a safety device pressure relief valve, which indeed allows the protection against high pressures, but is not suitable for hydraulic braking in the rule. This design allows a continuous slow running over a long period or a traction support even with full hydrostatic pressure accumulator.
