Description
Die Erfindung geht aus von einer Verbindungsvorrichtung für einen Antrieb, insbesondere einer elektrischen Maschine mit einer Verbrennungskraftmaschine oder einem Getriebe, sowie einem Verfahren zur Herstellung einer Verbindungsvorrichtung nach den Oberbegriffen der unabhängigen Ansprüche.The The invention is based on a connecting device for a Drive, in particular an electric machine with an internal combustion engine or a transmission, and a method for producing a Connecting device according to the preambles of the independent claims.
Nach dem Stand der Technik sind bei einem Hybridantrieb mit einer elektrischen Maschine und mit einer Verbrennungskraftmaschine Mittel zum Ausgleich eines axialen und/oder radialen Versatzes von Bauteilen bzw. Winkelabweichungen vorgesehen. Diese Toleranzausgleichsmittel werden z.B. zwischen einem eigen gelagerten Rotor der elektrischen Maschine und einer Kurbelwelle der Verbrennungskraftmaschine bzw. zwischen Rotor und Getriebeeingang angeordnet. Üblicherweise werden als Toleranzausgleichsmittel elastische, runde oder durch Ausnehmungen am Rand sternförmige Scheiben, so genannte „Flexplates", verwendet. Dabei werden Flexplate und Rotorwelle nach dem Stand der Technik durch eine Schraubenverbindung miteinander verbunden. Bei einer Lagerung des Rotors setzt die Schraubenverbindung zwischen Welle und Flexplate wegen des für eine Drehmomentübertragung nötigen Teilkreisdurchmessers eine axiale Bauraumverlängerung um mindestens eine Einschraubtiefe der Schraube voraus. Die axiale Bauraumverlängerung ist aus konstruktionstechnischen Gründen oft nicht möglich, so dass eine Vergrößerung des Lagerinnendurchmessers erforderlich ist. Dies verlangt jedoch den Einsatz von speziellen Dünnringlagern. Aufgrund von vorhandenen Belastungsprofilen kann sogar der Einsatz von teuren Sonderlagern erforderlich sein. Die Montage von derartigen Verbindungsvorrichtungen ist aufwändig und kostenintensiv. Durch den Einsatz von Sonderlagern kann außerdem ein Lieferengpass bei der Herstellung von z.B. Hybridantrieben entstehen.To The prior art are in a hybrid drive with an electric Machine and with an internal combustion engine means of compensation an axial and / or radial offset of components or angular deviations intended. These tolerance compensation means are e.g. between an internally mounted rotor of the electric machine and a Crankshaft of the internal combustion engine or between the rotor and Transmission input arranged. Usually are called tolerance compensation elastic, round or by Recesses on the edge star-shaped Washers, so-called "flexplates", used Flexplate and rotor shaft according to the prior art by a screw connection connected together. In storage of the rotor suspends the screw connection between shaft and flexplate of for a torque transmission necessary pitch circle diameter an axial space extension preceded by at least one screw-in depth of the screw. The axial Installation space extension is for constructional reasons often not possible so that enlargement of the Bearing internal diameter is required. However, this requires the Use of special thin-ring bearings. Due to existing load profiles can even use be required by expensive special camps. The assembly of such Connecting devices is complex and expensive. By The use of special warehouses can also be a delivery bottleneck the production of e.g. Hybrid drives arise.
Vorteile der ErfindungAdvantages of invention
Eine erfindungsgemäße Verbindungsvorrichtung für einen Antrieb, insbesondere einer elektrischen Maschine mit einer Verbrennungskraftmaschine oder einem Getriebe, umfasst eine drehbare Welle und ein mitdrehendes Toleranzausgleichsmittel, wobei eine Verbindungsstelle zwischen der Welle und dem Toleranzausgleichsmittel als Reibschweißverbindung ausgebildet ist. Ein erfindungsgemäßes Verfahren zur Herstellung einer Verbindungsvorrichtung wird durch Reibschweißen hergestellt. Dabei ist es von Vorteil, dass auf eine Schraubenverbindung zwischen Welle und Toleranzausgleichsmittel verzichtet werden kann, so dass sich eine axiale Bauraumverlängerung wegen des für eine Drehmomentübertragung nötigen Teilkreisdurchmessers erübrigt. Daher können Lager mit kleinem Durchmesser verwendet werden, und der vorhandene Bauraum reicht aus. Außerdem erübrigt sich der Einsatz von Schrauben, so dass sich der Aufwand bei der Montage einfacher gestaltet. Insgesamt kann auch die Montage schneller durchgeführt werden, und es sind keine Sonderlager, beispielsweise Dünnringlager, mehr erforderlich. Dadurch entfällt günstigerweise eine Abhängigkeit von der Verfügbarkeit von Sonderlagern, wodurch mögliche Wartezeiten wegen verspäteter Auslieferungen vermieden werden können. Vielmehr können großseriengefertigte kleine Lager verwendet werden, was die Fertigungskosten minimiert.A Connecting device according to the invention for one Drive, in particular an electric machine with an internal combustion engine or a transmission, includes a rotatable shaft and a co-rotating Tolerance compensation means, wherein a junction between the shaft and the tolerance compensation means as Reibschweißverbindung is trained. An inventive method for the preparation a connecting device is produced by friction welding. It is advantageous that a screw connection between Shaft and tolerance compensation means can be dispensed with, so that an axial space extension because of the for a torque transmission force Circumference diameter is unnecessary. Therefore can Small diameter bearings are used, and the existing one Space is sufficient. Furthermore Needless itself the use of screws, so that the effort in the Mounting made easier. Overall, the assembly can be faster carried out and there are no special warehouses, such as thin ring bearings, more required. This is eliminated favorably a dependency from the availability of special camps, which possible Waiting times due to late deliveries can be avoided. Rather, you can large mass-produced small bearings are used, which minimizes manufacturing costs.
Günstigerweise können durch Reibschweißen Stahlteile verschiedener Zusammenstellung miteinander verbunden werden. Es ist auch möglich, verschiedene Werkstoffe, beispielsweise Stahl und Aluminium, Stahl und Keramik usw., durch Reibschweißen miteinander zu verbinden. Die Welle und das Toleranzausgleichsmittel können somit aus verschiedenen Werkstoffen gefertigt sein. Reibschweißen erfolgt auf der Basis von Wärmediffusion. Eine Eindringtiefe von Aluminium in Korngrenzen von Stahl beträgt etwa 0,01 mm und ermöglicht eine belastbare, zuverlässige Verbindung zwischen den Bauteilen.conveniently, can by friction welding Steel parts of different composition connected become. It is also possible to have different Materials such as steel and aluminum, steel and ceramics etc., by friction welding to connect with each other. The shaft and the tolerance compensation device can thus be made of different materials. Friction welding takes place based on thermal diffusion. A penetration depth of aluminum into grain boundaries of steel is about 0.01 mm and allows a resilient, reliable Connection between the components.
Günstigerweise können die Welle und/oder das Toleranzausgleichsmittel aus gehärteten Werkstoffen gefertigt sein, denn eine Temperaturerhöhung beim Reibschweißen ist lokal, so dass bereits vorgehärtete Bauteile reibgeschweißt werden können, ohne dass die Härtung grundsätzlich beeinträchtigt wird. Einem Härterverlust kann durch gezielte Abkühlgeschwindigkeit entgegengewirkt werden. Je nach Härtegrad des Materials kann die Abkühlgeschwindigkeit beim Reibschweißen angepasst werden.conveniently, can the shaft and / or the tolerance compensation means made of hardened materials be made, because a temperature increase during friction welding is locally, so that already pre-cured Components friction welded can be without that curing in principle is impaired. A hardener loss can by targeted cooling rate be counteracted. Depending on the hardness of the material can the cooling rate during friction welding be adjusted.
Raue Oberflächen begünstigen das Reibschweißen, weil ein derartiges Verbindungsverfahren auf dem Entstehen von Reibungswärme beruht, welche bei rauen Oberflächen schneller erreicht werden kann. Bevorzugt wird somit eine Oberfläche der Welle und/oder des Toleranzausgleichsmittels wenigstens im Bereich der Verbindungsstelle vor dem Reibschweißen definiert aufgeraut. In einer bevorzugten Ausführung der erfindungsgemäßen Verbindungsvorrichtung ist das Toleranzausgleichsmittel aus Federstahl gefertigt, wobei es sich als besonders günstig erwiesen hat, eine Oberfläche des Federstahls zumindest partiell, z.B. im Bereich von Reibschweißstellen, aufzurauen, z.B. durch Sandstrahlen. Dadurch wird günstigerweise eine definierte Rauheit erreicht, um eine höhere Reibungswärme zu erzielen.rough surfaces favor friction welding, because such a bonding method is based on the generation of frictional heat, which on rough surfaces can be reached faster. Thus, a surface of the Shaft and / or tolerance compensation means at least in the area roughened defined the junction before friction welding. In a preferred embodiment the connecting device according to the invention the tolerance compensation means is made of spring steel, wherein It turns out to be especially cheap has proven a surface the spring steel at least partially, e.g. in the area of friction welding points, roughen, e.g. by sandblasting. This will be convenient Achieved a defined roughness to achieve a higher frictional heat.
Besonders bevorzugt werden die Welle und das Toleranzausgleichsmittel im Bereich der Verbindungsstelle gestaucht. Die Stauchung kann auf Welle und Toleranzausgleichsmittel gleich verteilt sein, indem Welle und Toleranzausgleichsmittel gegeneinander geführt werden. Je nach Formgebung kann jedoch auch vorgesehen sein, dass die Stauchung auf beide Werkstückteile unterschiedlich verteilt wird, so dass bei der Stauchung das Toleranzausgleichsmittel gegen die Welle oder umgekehrt geführt wird. Weist die Verbindungsstelle vor der Stauchung beispielsweise eine Länge von insgesamt 12 mm, also 6mm pro Bauteil, auf, kann nach der Stauchung beispielsweise nur noch eine Länge von 6 bis 8 mm übrig bleiben. Eine günstige Verkürzung kann durch Versuche ermittelt werden. Dies kann in einem Toleranzbereich von ± 0,3 mm reproduzierbar sein. Ein Gesamtrundlauffehler kann insbesondere höchstens 0,3 mm betragen. Bei einer serienmäßigen Fertigung können Toleranzen auch geringer ausfallen. Erfolgt die Bearbeitung der Welle nach dem Reibschweißen, spielen diese Toleranzen günstigerweise keine Rolle.Especially the shaft and the tolerance compensation means are preferred in the range the junction compressed. The compression can be on shaft and Tolerance compensation means be equally distributed by shaft and tolerance compensation means against each other become. Depending on the shape but can also be provided that the compression on both workpiece parts is distributed differently, so that during compression the tolerance compensation against the wave or vice versa becomes. Indicates the joint before compression, for example a length of a total of 12 mm, ie 6mm per component, on, can after compression for example, only one more length from 6 to 8 mm left stay. A cheap one shortening can be determined by experiments. This can be within a tolerance range of ± 0.3 mm be reproducible. A total round trip error can be especially at the most 0.3 mm. With a serial production tolerances can also lower. If the processing of the shaft after friction welding, play these tolerances conveniently not matter.
In einer günstigen Ausgestaltung umgibt die Verbindungsstelle eine Drehachse der Welle konzentrisch. Die Verbindungsstelle kann axial außerhalb, d.h. vor der Welle angeordnet sein oder auch so, dass sie die Welle konzentrisch umgibt. Das Toleranzausgleichsmittel ist vorzugsweise in der Art einer Scheibe ausgebildet, die konzentrisch zur Welle angeordnet ist. Dabei kann die Welle durch das Toleranzausgleichsmittel hindurch greifen oder das Toleranzausgleichsmittel kann auf eine Stirnseite der Welle aufgesetzt sein. Ist das Toleranzausgleichsmittel scheibenförmig ausgebildet, sitzt die Welle mit ihrer Stirnseite direkt auf der planen Scheibe auf. Das Toleranzausgleichsmittel und die Welle können an der Verbindungsstelle auch durch einen Bund beabstandet sein, wobei der Bund sowohl an der Welle als auch am Toleranzausgleichsmittel oder auch an beiden ausgebildet sein kann.In a cheap one Embodiment surrounds the connection point a rotation axis of the shaft concentric. The joint may be axially outward, i. be arranged in front of the shaft or even so that they concentric the shaft surrounds. The tolerance compensation means is preferably of the type a disc formed concentric with the shaft is. The shaft can pass through the tolerance compensation means grip or the tolerance compensation means can on a front page be put on the shaft. Is the tolerance compensation means disc-shaped, the shaft sits with its front side directly on the flat disc on. The tolerance compensator and the shaft can on the junction also be spaced by a collar, wherein the federal government on both the shaft and the tolerance compensation means or may be formed on both.
In einer günstigen Ausführungsform der erfindungsgemäßen Verbindungsvorrichtung kann das Toleranzausgleichsmittel an der Verbindungsstelle einen Bund ausbilden und hinter einer Stirnseite der Welle angeordnet sein. Dabei weist auch die Welle vorzugsweise einen zum Toleranzausgleichsmittel hin weisenden Rand oder Bund auf.In a cheap one embodiment the connecting device according to the invention the tolerance compensation means at the junction can Form collar and arranged behind a front side of the shaft be. In this case, the shaft preferably also has a tolerance compensation means pointing edge or covenant up.
Bei einer alternativen Ausführungsform kann das Toleranzausgleichsmittel mit einem Bund axial außerhalb an der Stirnseite der Welle angeordnet sein. Es kann auch vorgesehen sein, dass das Toleranzausgleichsmittel im Bereich der Verbindungsstelle flach axial außerhalb an der Stirnseite der Welle mit der Welle verbunden ist, wobei kein Bund an dem Toleranzausgleichsmittel ausgebildet ist. Je nach vorhandenem Bauraum und Ausgestaltung der Verbindungsvorrichtung kann zwischen diesen Varianten abgewechselt werden.at an alternative embodiment The tolerance compensation means can be with a collar axially outside be arranged on the front side of the shaft. It can also be provided be that the tolerance compensation means in the region of the joint flat axially outside at the front of the shaft is connected to the shaft, where no Bund is formed on the tolerance compensation means. Depending on the available Space and design of the connecting device can be between These variants are alternated.
