Abstract

The drive train has a clutch including a clutch basket (2) having a number of bar-shaped units e.g. rotors (4) of an electric motor, that extends in a direction of rotation axis (3) of the bar-shaped units. The bar-shaped units are mechanically and electrical conductively connected by two ring- or disk-shaped closure units (7, 8) in two axial ends (5, 6) of the basket such that the clutch basket is surrounded by a stator coaxial to the rotation axis. The bar-shaped units and the closure units are made of steel and screwed with each other.

Description

Die Erfindung betrifft einen Antriebsstrang eines Motorsportfahrzeugs, der eine Kupplung aufweist, die einen Kupplungskorb umfasst, wobei der Kupplungskorb eine Anzahl sich in Richtung seiner Drehachse erstreckende stabförmige Elemente aufweist.The The invention relates to a drive train of a motor sport vehicle, having a coupling comprising a clutch basket, wherein the clutch basket a number in the direction of its axis of rotation extending rod-shaped Has elements.

Allgemein bekannt ist es, dass Fahrzeuge mit Hybridantrieben versehen werden, d. h. sie erhalten neben dem klassischen Verbrennungsmotor noch einen Elektromotor, um mittels einer Batterie auch ohne Betrieb des Verbrennungsmotors fahren zu können. Gleichermaßen ist es bekannt, beide Antriebsarten zu kombinieren, d. h. den Verbrennungsmotor und den Elektromotor gleichzeitig zu betreiben.Generally it is known that vehicles are provided with hybrid drives, d. H. they still get alongside the classic internal combustion engine an electric motor, by means of a battery without operation to drive the internal combustion engine. Equally is it is known to combine both types of drive, d. H. the internal combustion engine and to operate the electric motor at the same time.

Auch im Motorsport kann ein solches Konzept sinnvoll sein. Hier allerdings stellt sich das Problem, dass eine besonders platzsparende Unterbringung des Elektromotors erforderlich ist, da die Platzverhältnisse hier zumeist noch wesentlich beengter sind als bei Serienfahrzeugen. Namentlich ist der radiale Bauraum zumeist stark begrenzt.Also In motor sports, such a concept can make sense. Here, however poses the problem that a particularly space-saving accommodation the electric motor is required because of the space available here are still much more cramped than standard vehicles. In particular, the radial space is usually very limited.

Ein anderes Problem ist es, dass das Massenträgheitsmoment des Antriebsstranges eines Motorsportfahrzeugs möglichst gering sein muss, um eine hohe Dynamik des Fahrzeugs zu erreichen. Demgemäß ist es in der Regel nicht akzeptabel, zusätzliche Elemente, wie einen Elektromotor, in den Antriebsstrang zu integrieren, da dies dem genannten Ziel einer hohen Fahrdynamik zuwider laufen würde.One Another problem is that the mass moment of inertia of the drive train a motor sport vehicle as possible must be low in order to achieve high dynamics of the vehicle. Accordingly, it is usually not acceptable, additional elements, like one Electric motor to integrate into the drive train, since this is the would be contrary to the objective of high driving dynamics.

Entsprechendes gilt auch mit Blick auf das Gewicht des Fahrzeugs und damit auch des Antriebsstranges, das möglichst gering sein muss. Die Integration eines Elektromotors würde hier kontraproduktiv wirken.The same also applies with regard to the weight of the vehicle and thus also the drive train, the possible must be low. The integration of an electric motor would be here counterproductive.

Der Erfindung liegt die Aufgabe zugrunde, einen Antriebsstrang der eingangs genannten Art so fortzubilden, dass es möglich wird, einen Elektromotor für einen hybriden Antrieb in ihn zu integrieren, ohne dass sich der benötigte Bauraum, insbesondere der radiale Bauraum, wesentlich erhöht und ohne, dass sich das Massenträgheitsmoment des Antriebsstrangs erhöht. Ferner soll der zu integrierende Elektromotor möglichst leicht sein.Of the Invention is based on the object, a drive train of the beginning so-called type so that it becomes possible, an electric motor for one integrate hybrid propulsion into it without the required space, in particular the radial space, substantially increased and without that the Moment of inertia of the drive train increases. Furthermore, the electric motor to be integrated should be as light as possible.

Die Lösung dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass die stabförmigen Elemente des Kupplungskorbes in ihren beiden axialen Enden über zwei ring- oder scheibenförmige Abschlusselemente mechanisch und elektrisch leitend verbunden sind, wobei der Kupplungskorb von einem Stator koaxial zur Drehachse umgeben ist.The solution this object by the invention is characterized in that the rod-shaped Elements of the clutch basket in its two axial ends over two ring-shaped or disk-shaped Terminals are mechanically and electrically connected, wherein the clutch basket surrounded by a stator coaxial with the axis of rotation is.

Gemäß der Erfindung wird also der Kupplungskorb der Kupplung, der als solcher üblicherweise verwendet wird, so umfunktioniert, dass er gleichzeitig als Rotor eines Elektromotors fungiert. Er wird wie angegeben ausgestaltet und von einem Stator koaxial umgeben.According to the invention So is the clutch basket of the clutch, as such usually is used, so converted that at the same time as a rotor an electric motor acts. It is designed as indicated and coaxially surrounded by a stator.

Der Stator und der Kupplungskorb bilden demgemäß einen Elektromotor, vorzugsweise einen elektrischen Asynchronmotor. Der Asynchronmotor kann – wie an sich üblich – einen Frequenzumrichter umfassen.Of the Stator and the clutch basket accordingly form an electric motor, preferably an electric asynchronous motor. The asynchronous motor can - as on usual - one Include frequency inverters.

Der Stator hat vorzugsweise drei Paar elektrische Wicklungen. Der Kupplungskorb hat mit Vorteil zwischen acht und zwölf stabförmige Elemente; diese sind zumeist äquidistant um den Umfang des Kupplungskorbs verteilt angeordnet.Of the Stator preferably has three pairs of electrical windings. The clutch basket has between eight and twelve rod-shaped elements with advantage; these are mostly equidistant arranged distributed around the circumference of the clutch basket.

Wenngleich im Rennsport üblicherweise Titan als Material für den Kupplungskorb verwendet wird, ist es von Vorteil, wenn die stabförmigen Elemente aus Stahl bestehen. Auch die ring- oder scheibenförmigen Abschlusselemente können aus Stahl bestehen. Damit wird eine bessere elektrische Leitfähigkeit erreicht, auf die es vorliegend ankommt.Although in racing usually Titanium as material for the clutch basket is used, it is advantageous if the rod-shaped elements Made of steel. Also the ring or disk-shaped closing elements can Made of steel. This will give better electrical conductivity achieved, which is important in the present case.

Eines der ring- oder scheibenförmigen Abschlusselemente und die stabförmigen Elemente können einstückig ausgebildet sein. Das andere ring- oder scheibenförmige Abschlusselement und die stabförmigen Elemente können miteinander verschraubt sein.One the ring-shaped or disc-shaped End elements and the rod-shaped Elements can one piece be educated. The other ring-shaped or disk-shaped closing element and the rod-shaped Elements can be screwed together.

Der Erfindungsvorschlag kommt vor allem bei einem Rennwagen zum Einsatz, worunter auch ein Formel-1-Wagen zu verstehen sein kann.Of the Invention proposal is mainly used in a race car, including a Formula 1 car can be understood.

Durch die vorgeschlagene Konstruktion wird es möglich, einen Elektromotor zwecks Hybridantrieb in ein Motorsportfahrzeug zu integrieren, ohne dass das Massenträgheitsmoment des Antriebsstranges erhöht wird. Auch das für den Elektromotor erforderliche zusätzliche Gewicht bleibt in untergeordneten Bereichen, da der Kupplungskorb den Rotor des Elektromotors darstellt und insofern überhaupt kein Zusatzgewicht bedingt ist. Nur der Stator kommt additiv hinzu.By The proposed construction makes it possible to use an electric motor for the purpose To integrate hybrid propulsion into a motor sport vehicle without that Moment of inertia of the drive train increased becomes. That too for additional weight required by the electric motor remains in subordinate areas, because the clutch basket represents the rotor of the electric motor and insofar at all no additional weight is conditional. Only the stator is additively added.

Durch den vorgeschlagenen Aufbau ist auch der Platzbedarf gering; es wird lediglich der radial relativ schmal bauende Stator erforderlich.By the proposed structure is also the space required low; it will only the radially relatively narrow stator is required.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen:In the drawing is an embodiment of Invention shown. Show it:

1 eine perspektivische Darstellung eines Kupplungskorbes einer Kupplung eines Rennsportfahrzeugs und 1 a perspective view of a clutch basket of a clutch of a racing vehicle and

2 die Ansicht eines alternativ ausgebildeten Kupplungskorbes samt einem diesen koaxial umgebenden Stator, gesehen in Achsrichtung. 2 the view of an alternatively formed clutch basket including a coaxially surrounding this stator, seen in the axial direction.

In 1 ist der schematische Aufbau eines Elektromotors zu sehen, wie er erfindungsgemäß zum Einsatz kommt, um ein Motorsportfahrzeug für den Hybridantrieb auszustatten. Schematisch dargestellt ist eine Kupplung 1, gesehen in Richtung der Drehachse 3 derselben, die aus einem drehbar gelagerten Kupplungskorb 2 mit Fußgehäuse besteht, der koaxial zur Drehachse 3 von einem Stator 9 umgeben ist.In 1 is the schematic structure of an electric motor to see how it is used according to the invention to equip a motor sports car for the hybrid drive. Schematically illustrated is a clutch 1 , seen in the direction of the axis of rotation three the same, consisting of a rotatably mounted clutch basket 2 with foot housing coaxial with the axis of rotation three from a stator 9 is surrounded.

Wie in der Zusammenschau mit 2 zu erkennen ist (die einen Kupplungskorb 2 in einer etwas anderen Ausgestaltung zeigt), hat der Kupplungskorb 2 eine Anzahl stabförmiger Elemente 4, die sich in Richtung der Drehachse 3 erstrecken.As in the synopsis with 2 to recognize (which is a clutch basket 2 in a slightly different embodiment shows), the clutch basket has 2 a number of rod-shaped elements 4 moving in the direction of the axis of rotation three extend.

In den axialen Enden 5 bzw. 6 des Kupplungskorbes 2 ist je ein ring- oder scheibenförmiges Abschlusselement 7 bzw. 8 angeordnet. Wesentlich ist, dass die ring- oder scheibenförmigen Abschlusselemente 7, 8 zusammen mit den stabförmigen Elementen 4 eine mechanisch feste und elektrisch leitende Verbindung bilden. Dies ist erforderlich um den Kupplungskorb 2 als Rotor des Elektromotors tauglich zu machen. Hierzu sind im Ausführungsbeispiel gemäß 2 das eine scheibenförmige Abschlusselement 7 und die stabförmigen Elemente 4 einstückig ausgeführt, d. h. vorliegend aus einem Stahlrohling durch Fräsen gearbeitet. Das ringförmige Abschlusselement 8 ist an die rechten Stirnseiten der stabförmigen Elemente 4 angesetzt und mittels Schrauben 11 fixiert.In the axial ends 5 respectively. 6 of the clutch basket 2 is ever a ring or disk-shaped closing element 7 respectively. 8th arranged. It is essential that the ring-shaped or disc-shaped end elements 7 . 8th together with the rod-shaped elements 4 form a mechanically strong and electrically conductive connection. This is required around the clutch basket 2 as a rotor of the electric motor suitable. For this purpose, according to the embodiment 2 the one disk-shaped closing element 7 and the rod-shaped elements 4 executed in one piece, ie in the present case worked from a steel blank by milling. The annular end element 8th is at the right end sides of the rod-shaped elements 4 attached and by means of screws 11 fixed.

Koaxial zur Drehachse 3 umgeben ist der Rotor 2, d. h. der Kupplungskorb, von dem Stator 9. Um den Umfang des Stators 9 herum sind insgesamt drei Paare elektrischer Wicklungen 10 (Spulenpaare) angeordnet.Coaxial to the axis of rotation three surrounded is the rotor 2 ie the clutch basket, from the stator 9 , Around the circumference of the stator 9 There are a total of three pairs of electrical windings around 10 (Coil pairs) arranged.

Die dargestellte Anordnung gemäß 1 arbeitet als Asynchronmotor mit Frequenzumrichter, wie er als elektrischer Antrieb hinlänglich bekannt ist. Der Stator 9 dieses Asynchronmotors besteht also aus 3 Paaren Wicklungen, die mit je einer der drei Phasen des Drehstroms gespeist werden. Der Rotor 4 besteht indes nur aus den elektrisch leitenden Stäben 4, die parallel zur Drehachse 3 des Motors bzw. der Kupplung 1 auf einem definierten Durchmesser angeordnet sind und die an ihren Enden miteinander elektrisch und mechanisch verbunden sind. Das vom Stator 9 erzeugte Drehfeld induziert bei der Überholung des Rotors in den Stäben 4 einen Strom, der wiederum ein Stator-eigenes Magnetfeld erzeugt. Diese beiden Magnetfelder sorgen zusammen für das Antriebsmoment.The illustrated arrangement according to 1 works as an asynchronous motor with frequency converter, as it is well known as an electric drive. The stator 9 This asynchronous motor thus consists of 3 pairs of windings, which are fed with one of the three phases of the three-phase current. The rotor 4 consists however only of the electrically conductive rods 4 parallel to the axis of rotation three of the engine or the clutch 1 are arranged on a defined diameter and which are connected to one another at their ends electrically and mechanically. That from the stator 9 generated rotating field induced in the overhaul of the rotor in the rods 4 a current, which in turn generates a stator own magnetic field. These two magnetic fields together provide the drive torque.

Das so ausgestatte Fahrzeug kann mithin im Hybridbetrieb betrieben werden.The so equipped vehicle can therefore be operated in hybrid mode.

Der Kupplungskorb 2 ist in dieser oder ähnlicher Form ein ohnehin vorhandenes Bauteil und kann in seiner Form ohne Änderungen für den genannten Einsatz genutzt werden, einschließlich der benötigten Lagerung, die ebenfalls schon vorhanden ist.The clutch basket 2 is in this or similar form an already existing component and can be used in its form without changes for the said use, including the required storage, which also already exists.

Da bei der Kupplung im Rennsport zumeist ein Reibpaket aus Carbon zum Einsatz kommt, das nicht elektrisch leitend ist, wird die angestrebte Funktion des Rotors hierdurch nicht gestört.There in the clutch in racing mostly a friction package made of carbon for Use comes, which is not electrically conductive, is the desired Function of the rotor thereby not disturbed.

Der Wirkungsgrad des Rotors wird bei Verwendung von Stahl statt Titan wegen der besseren Leitfähigkeit von Stahl verbessert.Of the Efficiency of the rotor is when using steel instead of titanium because of better conductivity improved by steel.

Nur der Stator muss bei der Realisierung des Erfindungsvorschlags zusätzlich im Fahrzeug untergebracht werden. Allerdings erhöht er das Massenträgheitsmoment des Antriebsstranges nicht.Just the stator must be additionally implemented in the realization of the proposed invention Vehicle can be accommodated. However, it increases the moment of inertia the drive train not.
