Description

Verbrennungsmotor mit in einem Kurbelgehäuse gelagerter Kurbelwelle, wobei der Starter/Generator auf der Kurbelwelle angeordnet ist Internal combustion engine with a crankshaft mounted in a crankcase, the starter / generator being arranged on the crankshaft
B E S C H R E I B U N GDESCRIPTION
Die Erfindung betrifft einen Verbrennungsmotor mit in einem Kurbelgehäuse gelagerter Kurbelwelle, wobei der Starter/Generator auf der Kurbelwelle innerhalb des Kurbelgehäuses angeordnet ist.The invention relates to an internal combustion engine with a crankshaft mounted in a crankcase, the starter / generator being arranged on the crankshaft within the crankcase.
Ein derartiger Verbrennungsmotor ist beispielsweise aus der EP 0876 554B1 oder aus der DE 199 13 656 C1 bekannt. Der Starter/Generator und der Verbrennungsmotor sind jeweils baulich getrennt axial hintereinander auf der Kurbelwelle angeordnet, wobei sich der Starter/Generator mit seinem Rotor auf der Kurbelwelle oder deren Verlängerung drehfest sitzt und mit seinem Stator drehtest gegen den Verbrennungsmotor oder ein Kupplungsgehäuse abstützt. Derartige Verbrennungsmotoren ermöglichen sowohl ein zuverlässiges Starten des Motors mit Hilfe des Starter/Generators, da die zum Starten erforderlichen hohen Drehmomente direkt in die Kurbelwellen eingeleitet und von diesen aufgrund ihres großen Außendurchmessers gut aufgenommen werden können, als auch die einfache Erzeugung elektrischer Energie direkt an der Kurbelwelle und dies mit nur einer einzigen Maschine. Zusätzliche verlustbringende, wartungsintensive Bauteile können entfallen. Eine derartige Ausbildung erfordert jedoch die Bereitstellung eines relativen großen Bauvolumens sowohl für den Verbrennungsmotor als auch für den Starter/Generator, was dessen Einsatzmöglichkeiten in einem Fahrzeug erheblich einschränkt. Aufgrund der jeweils individuell bei der Fahrzeugkonstruktion zu berücksichtigenden Anforderungen an ein Kraftfahrzeug kann der für eine derartige Ausbildung erforderliche Bauraum vielfach entweder nicht zur Verfügung gestellt werden oder nur unter Inkaufnahme des Verzichts auf sonstige den Bauraum erfordernden Aggregate mit deren Vorteilen bereitgestellt werden. Die Vorteile der bekannten Verbrennungsmaschine können somit nur in stark eingeschränktem Umfang bei wenigen Kraftfahrzeugen ohne Einschränkung sonstiger individuell gestellter Anforderungen an das Kraftfahrzeug genutzt werden. Zur Sicherstellung der Vorteile des Starter/Generators muss bei derartigen Ausbildungen darüber hinaus die Kurbelwelle außerhalb des Verbrennungsmotors noch ausreichend lang für die funktionssichere Anordnung und Montage und Demontage des Starter/Generators ausgebildet werden, so dass auch die Kupplung erst in großem Abstand vom Verbrennungsmotor ausgebildet werden kann. Die Einsatzmöglichkeiten eines Starter/Generators und somit die Nutzung seiner Vorteile in einem Kraftfahrzeug werden hierdurch noch weiter auf wenige, diese baulichen Erfordernisse gewährleistenden Kraftfahrzeuge beschränkt.Such an internal combustion engine is known for example from EP 0876 554B1 or from DE 199 13 656 C1. The starter / generator and the internal combustion engine are each structurally separated axially one behind the other on the crankshaft, the starter / generator with its rotor sitting on the crankshaft or its extension in a rotationally fixed manner and with its stator rotating test being supported against the internal combustion engine or a clutch housing. Such internal combustion engines enable both reliable starting of the engine with the help of the starter / generator, since the high torques required for starting are introduced directly into the crankshafts and can be easily absorbed by them due to their large outer diameter, as well as the simple generation of electrical energy directly on the Crankshaft and this with only one machine. Additional loss-making, maintenance-intensive components can be omitted. However, such a design requires the provision of a relatively large construction volume both for the internal combustion engine and for the starter / generator, which considerably limits its possible uses in a vehicle. Due to the individual requirements of a motor vehicle to be taken into account when designing the vehicle, the installation space required for such training can either not be made available or can only be provided with the advantages of doing without other units requiring the installation space. The advantages of the known internal combustion engine can therefore only be used to a very limited extent in a small number of motor vehicles without any other individual requirements being placed on it Motor vehicle can be used. In order to ensure the advantages of the starter / generator, the crankshaft outside the internal combustion engine must also be long enough for the function-safe arrangement and assembly and disassembly of the starter / generator, so that the clutch is only formed at a large distance from the internal combustion engine can. The possible uses of a starter / generator and thus the use of its advantages in a motor vehicle are hereby further restricted to a few motor vehicles which ensure these structural requirements.

Bei dieser Ausführung ist der Rotor im Bereich des Kurbelwellenlagers auf der Kurbelwelle verbaut und Rotor und Stator erstrecken sich radial um das Kurbelwellenlager. Aufgrund der Durchmesser des Kurbelwellenlagers sind die bei einer derartigen Ausbildung eines Verbrennungsmotors mit Starter/Generator erzielbaren Drehmomente deutlich beschränkt.From DE 100 23 124 C1 an internal combustion engine according to the features of the preamble of claim 1 is known. In this embodiment, the rotor is installed on the crankshaft in the region of the crankshaft bearing and the rotor and stator extend radially around the crankshaft bearing. Due to the diameter of the crankshaft bearing, the torques that can be achieved with such an embodiment of an internal combustion engine with a starter / generator are clearly limited.

Der Starter/Generator ist somit in den Verbrennungsmotor integriert ausgebildet. Die Integration innerhalb des Kurbelgehäuses kann ohne große Vergrößerung des Kurbelgehäuses ermöglicht werden. Außerhalb des Verbrennungsmotors kann der Bauraum trotz Nutzung der Vorteile des Starter/Generators optimal entsprechend den sonstigen individuellen Erfordernisse an das Kraftfahrzeug verplant und ge- nutzt werden. Zum Starten können die für den Start erforderlichen hohen Drehmomente sicher über den Starter/Generator erzeugt und von der Kurbelwelle aufgenommen werden. Die Erzeugung der elektrischen Energie kann vom Starter/Generator direkt an der Kurbelwelle erfolgen. Der Einsatz dieser Vorteile kann auch an Fahrzeugen mit Längsmotor und kurzer Motorbauraumlänge erfolgen.According to the invention, the problem is solved by designing an internal combustion engine with a crankshaft mounted in a crankcase, a starter / generator being arranged on the crankshaft, according to the features of claim 1, in which the starter / generator is in a position within the crankcase of the internal combustion engine on the Crankshaft is arranged and the rotor of the starter / generator is in the axial position of at least one balance weight or a crank arm of the crankshaft on the crankshaft and the stator of the starter / generator in the crankcase is fixed to the housing.

Besonders einfach und vorteilhaft ist die Ausbildung gemäß den Merkmalen von Anspruch 2, bei der das Ausgleichsgewicht der Kurbelwelle selbst als Rotor des Starter/Generators ausgebildet ist. Eine derartige Ausbildung ist besonders raumsparend und bauteilreduzierend ausführbar.The embodiment according to the features of claim 2, in which the counterweight of the crankshaft itself is designed as a rotor of the starter / generator, is particularly simple and advantageous.

Ein herkömmliches Ausgleichsgewicht muss lediglich mit einem oder mehreren Permanentmagneten bestückt werden. Der so ausgebildete Rotor des Starter/Generators kann ohne besondere baulichen Veränderungen im herkömmlichen Motor integriert werden und mit dem ebenfalls einfach gegenüber dem Rotor im Kurbelgehäuse fixierbaren Stator mit geringem Aufwand platzminimierend betrieben werden.A design according to the features of claim 3, in which the stator of the starter / generator in the crankcase is fixed to the housing with induction coils and the balance weight with one or more permanent magnets, enables a starter / generator to be designed in a functionally reliable and space-optimized manner in the internal combustion engine in a particularly simple manner.

Darüber hinaus ermöglicht diese Ausbildung einen Einsatz einer einmalig bestückten Kurbelwelle sowohl in einem Motor einzusetzen, bei dem den jeweiligen Anforderungen entsprechend zu jedem Rotor ein korrespondierender Stator ausgebildet ist, als auch in einem Motor, bei dem den jeweiligen Anforderungen entsprechend nur zu einzelnen Rotoren korrespondierende Statoren ausgebildet sind. Die Ausbildung gemäß den Merkmalen von Anspruch 10, wobei zu wenigstens einem Rotor ein korrespondierender Stator ausgebildet ist und wobei zu wenigstens einem Rotor kein korrespondierender Stator ausgebildet ist, ermöglicht eine weitere Vergrößerung des Einsatzbereiches einer standardmäßig mit Rotoren bestückten Kurbelwelle.

Die Figuren zeigt einen mehrzylindrischen Verbrennungsmotor mit einer Zylinderbank 1. Im Zylinderkurbelgehäuse 2 sind mehrere Zylinder 9 ausgebildet, von denen lediglich 2 dargestellt sind. Im unteren Bereich des Zylinderkurbelgehäuses 2 ist eine Kurbelwelle 6 drehbar gelagert ausgebildet, die in herkömmlicher Weise über Pleuelstangen 7 mit jeweils in einem Zylinder 9 verschiebbar gelagerten Kolben 8 in Antriebsverbindung stehen.The figures show a multi-cylinder internal combustion engine with a cylinder bank 1. A plurality of cylinders 9 are formed in the cylinder crankcase 2, of which only 2 are shown. In the lower region of the cylinder crankcase 2, a crankshaft 6 is rotatably mounted, which are connected in a conventional manner via connecting rods 7 with pistons 8 each slidably mounted in a cylinder 9.
In bekannter, herkömmlicher Weise ist die Kurbelwelle 6 mit Ausgleichsgewichten 11 ausgebildet. Wie in den Figuren dargestellt ist, ist auf den Ausgleichsgewichten 11 jeweils ein Haltering 14 konzentrisch zur Kurbelwellenachse befestigt. Der Haltering 14 ist über den Umfang gleichmäßig verteilt an seiner radial äußeren Ringfläche mit identischen Permanentmagneten 13 bestückt. Hierzu sind die Permanentmagneten 13 beispielsweise in Vertiefungen im Haltering eingelassen befestigt. Ausgleichsgewicht 11 , darauf befestigter Haltering 14 mit Permanentmagneten 13 bilden den Rotor 12 eines Stator/Generator. Radial außerhalb der Permanentmagneten 13 ist ein Stator 15 im unteren Bereich 3 des Zylinderkurbelgehäuses 2 befestigt. Der Stator 15 ist in bekannter Weise mit in Umfangsrichtung auf einem konzentrischen Kreis zur Kurbelwelle verteilten und zur Sicherung der Wirkverbindung mit den Permanentmagneten 13 des Rotors 12 zu diesen ausgerichteten Sta- torspulen17 ausgebildet, die in bekannter nicht dargestellter Weise mit der Energieversorgungseinrichtung und mit der Motorsteuereinrichtung des Fahrzeugs verbunden sind. Im dargestellten Ausführungsbeispiel ist der Stator 15 aus zwei in Umfangsrichtung von einander beabstandeten Um- fangssegmenten ausgebildet, die beiderseits der Kurbelwelle 6 im unteren Bereich 3 des Zylinderkurbelgehäuses 2 befestigt sind. Jedes Umfangsseg- ment ist mit einem Eisenkern 16 und in Umfangsrichtung verteilten Statorspulen 17 ausgebildet.In a known, conventional manner, the crankshaft 6 is designed with counterweights 11. As shown in the figures, a retaining ring 14 is attached concentrically to the crankshaft axis on the counterweights 11. The retaining ring 14 is evenly distributed on its radially outer ring surface with identical permanent magnets 13. For this purpose, the permanent magnets 13 are, for example, fastened in recesses in the retaining ring. Balance weight 11, retaining ring 14 fastened thereon with permanent magnets 13 form the rotor 12 of a stator / generator. A stator 15 is fastened radially outside of the permanent magnets 13 in the lower region 3 of the cylinder crankcase 2. The stator 15 is formed in a known manner with stator coils 17 which are distributed in the circumferential direction on a concentric circle to the crankshaft and to ensure the operative connection with the permanent magnets 13 of the rotor 12 which are oriented in a known manner, not shown, with the energy supply device and with the engine control device connected to the vehicle. In the exemplary embodiment shown, the stator 15 is formed from two circumferential segments which are spaced apart from one another in the circumferential direction and which are located on both sides of the crankshaft 6 in the lower one Area 3 of the cylinder crankcase 2 are attached. Each circumferential segment is formed with an iron core 16 and stator coils 17 distributed in the circumferential direction.

Above the cylinder crankcase, a cylinder head, not shown, is fastened in a known manner, not shown, in a sealing manner.
Zum Starten des Motors wird von einer Steuereinrichtung gesteuert elektrische Spannung von der Energieversorgungseinrichtung an die Statorspulen 17 des Stators 15 derart angelegt, dass der Rotor 12 durch die zwischen Statorspulen 17 und Permanentmagneten 13 induzierten Kräfte so verdreht wird. Dabei sind Permanentmagneten und Statorspulen 17 so ausgebildet, dass ein zum Starten des Verbrennungsmotors ausreichendes Drehmoment auf die Kurbelwelle 6 übertragen wird. Nach erfolgreichem Start wird die Spannung wieder gesteuert abgebaut. Die Kurbelwelle 6 wird in üblicherweise nach dem Start durch die aufgrund der Verbrennung im Zylinder erzeugte Kolbenbewegung und deren Übertragung über die Pleuelstangen 7 auf die Kurbelwelle angetrieben.To start the motor, electrical voltage is applied to the stator coils 17 of the stator 15 in a manner controlled by a control device in such a way that the rotor 12 is rotated by the forces induced between the stator coils 17 and permanent magnets 13. In this case, permanent magnets and stator coils 17 are designed such that a torque sufficient to start the internal combustion engine is transmitted to the crankshaft 6. After a successful start, the voltage is reduced again in a controlled manner. The crankshaft 6 is usually driven after the start by the piston movement caused by the combustion in the cylinder and its transmission via the connecting rods 7 to the crankshaft.
In diesem Zustand wird durch die mitgedrehten Permanentmagneten 13 des Rotors 12 in den Statorspulen 17 Strom induziert, der soweit Bedarf an Erzeugung elektrischer Energie im Fahrzeug besteht, gesteuert der Energieversorgungseinrichtung zugeführt wird.In this state, the permanent magnets 13 of the rotor 12, which are also rotated, induce current in the stator coils 17, which current is supplied to the energy supply device in a controlled manner as far as there is a need for generating electrical energy in the vehicle.
Oberhalb der Kurbelwelle 6 sind die beiden Segmente des Stators 15 so weit voneinander beabstandet, dass ihr Abstand wenigstens dem Bohrungsdurchmesser der benachbarten Zylinder entspricht.Above the crankshaft 6, the two segments of the stator 15 are spaced so far apart that their distance corresponds at least to the bore diameter of the adjacent cylinders.
In einer anderen in seiner Höhenerstreckung sehr niedrig ausbildbaren Ausführungsform des Motors sind die beiden Segmente des Stators 15 unterhalb und oberhalb der Kurbelwelle 6 jeweils wenigstens so weit voneinander beabstandet, dass der Rotor mit seinem Außendurchmesser nach oben und nach unten wenigstens soweit erstreckt wie die Statorsegmente.In another embodiment of the motor which can be designed to be very low in terms of its height, the two segments of the stator 15 below and above the crankshaft 6 are each at least so far apart that the outer diameter of the rotor extends up and down at least as far as the stator segments.

Aber auch bei diesen Ausführungsformen ist wenigstens ein Ausgleichsgewichten der Kurbelwelle 6 mit Starter/Generator ausgebildet.In the illustrated embodiments, a balance weight with a stator / generator is formed axially between the connecting rods of the various cylinders. In other exemplary embodiments, which are not shown, a starter / generator is not formed on all balance weights of the crankshaft 6, but at least one balance weight is formed without a starter / generator. But even in these embodiments, at least one balancing weight of the crankshaft 6 with starter / generator is formed.
In den dargestellten Ausführungsformen ist zwar nur eine Zylinderbank 1 eines Reihenmotors dargestellt. Allerdings sind die dargestellten und die beschriebenen Ausführungsformen auch in analoger Ausführung mit mehreren Zylinderbänken möglich. Die Ausführungsformen sind ebenso in Reihen, wie in V-, in VR- oder in W-Anordnung und bei den Boxermotoren analog möglich.
