Description

Lamellenkupplung für Kraftfahrzeuge, insbesondere MotorräderMulti-plate clutch for motor vehicles, especially motorcycles
Die Erfindung betrifft eine Lamellenkupplung für Kraftfahrzeuge, insbesondere Motorräder, umfassend ein mit dem Schwungrad eines Verbrennungsmotors gekuppeltes Primärrad, das auf einer Getriebeeingangswelle drehbar gelagert ist, einen mit dem Primärrad starr verbundenen Kupplungskorb, einen zur Getriebeeingangswelle konzentrisch angeordneten und mit dieser starr verbundenen Mitnehmer, eine mit dem Mitnehmer axial verschiebbar, aber drehfest verbundene Druckplatte, einen mit der Druckplatte starr verbundenen Drucktopf, eine Membranfeder, die sich an einem äußeren Umfangsbereich an dem Mitnehmer und an einem inneren Umfangsbereich an dem Drucktopf abstützt, ein Paket ringförmiger Kupplungslamellen, die abwechselnd am Innen oder Außenumfang mit dem Mitnehmer, bzw. mit dem Korb drehfest, aber axial verschiebbar verbunden sind, wobei die Lamellen zwischen der Druckplatte und dem Mitnehmer eingespannt sind, ein zur Getriebeeingangswelle koaxial angeordnetes Ausrücklager, über das eine axiale Ausrückkraft auf die Druckplatte übertragbar ist, und einen in den Innenring des Ausrücklagers eingesetzten und mit einem Ringflansch an demselben anliegenden Druckpilz.The invention relates to a multi-plate clutch for motor vehicles, especially motorcycles comprising a primary wheel coupled to the flywheel of an internal combustion engine, which is rotatably mounted on a transmission input shaft, a clutch basket rigidly connected to the primary wheel, a concentrically arranged to the transmission input shaft and rigidly connected to this driver with the driver axially displaceable, but rotatably connected pressure plate, a rigidly connected to the pressure plate pressure pot, a diaphragm spring, which is supported on an outer peripheral portion of the driver and an inner peripheral portion of the pressure pot, a package of annular clutch plates, which alternately on the inside or outer circumference with the driver, or with the basket rotatably, but axially displaceably connected, wherein the lamellae are clamped between the pressure plate and the driver, a coaxially arranged to the transmission input shaft release bearing, on the an axial disengaging force is transferable to the pressure plate, and a pressure mushroom inserted into the inner ring of the release bearing and with an annular flange on the same.
Herkömmliche Lamellenkupplungen dieser Bauart haben häufig eine Membranfeder mit einer plateauförmigen Federkennlinie. Der Betriebspunkt und der Ausrückpunkt der Kupplung liegen dabei im linearen horizontalen Bereich der Federkennlinie. Das bedeutet, dass im Betriebspunkt und im Ausrückpunkt der Kupplung die gleiche Federkraft herrscht. Mit anderen Worten die zum Öffnen der Kupplung erforderliche Kraft ist mit der im geschlossenen Zustand der Kupplung herrschenden Federkraft identisch.Conventional multi-plate clutches of this type often have a diaphragm spring with a plateau-shaped spring characteristic. The operating point and the disengagement point of the clutch lie in the linear horizontal region of the spring characteristic. This means that the same spring force prevails at the operating point and in the disengagement point of the clutch. In other words, the force required to open the clutch is identical to the spring force prevailing in the closed state of the clutch.
Aufgrund von unvermeidbaren Toleranzen der verschiedenen Bauteile einer solchen Lamellenkupplung liegt der Angriffspunkt des Nehmerzylinders für die Betätigung der Kupplung nie genau auf der Drehachse der Kupplung. Das bedeutet, dass der Geberzylinder exzentrisch über den Druckpilz und das Ausrücklager auf die Druckplatte drückt. Bei einer herkömmlichen Membranfeder mit linearer Kennlinie führt dies lediglich zu einer geringfügigen Schiefstellung der Druckplatte, da die progressive Feder mit einer höheren Gegenkraft reagiert. Dies gilt, grundsätzlich auch für eine Membranfeder mit einer plateauförmigen Federkennlinie.Due to unavoidable tolerances of the various components of such a multi-plate clutch, the point of application of the slave cylinder for the actuation of the clutch is never exactly on the axis of rotation of the clutch. This means that the Press eccentric encoder cylinder over the pressure mushroom and the release bearing on the pressure plate. In a conventional diaphragm spring with linear characteristic, this only leads to a slight misalignment of the pressure plate, since the progressive spring reacts with a higher reaction force. This applies, in principle, for a diaphragm spring with a plateau-shaped spring characteristic.
Bei Motorrädern mit hoher Leistung kann die zum Auskuppeln erforderliche Handkraft, die der Fahrer auf den Kupplungshebel ausüben muß, erhebliche Werte annehmen. Bei Verwendung einer Membranfeder mit plateauförmiger Federkennlinie ist die auf den Kupplungshebel auszuübende Handkraft über den gesamten Betätigungsweg konstant. Zur Verringerung der zum Auskuppeln erforderlichen Handkraft und der dabei zu bewältigenden Arbeit wird die Verwendung einer Membranfeder mit einer ab dem Betriebspunkt in Betätigungsrichtung degressiven Kennlinie vorgeschlagen. Durch diese fallende Kennlinie läßt sich auf kostengünstige Art und Weise die zum Öffnen der Kupplung erforderliche Arbeit verringern, weil die Handkraft über den Weg des Kupplungshebels abnimmt. Dies bedeutet einen deutlichen Komfortgewinn für den Fahrer. Wegen der aus den vorstehend genannten Gründen exzentrischen Belastung der Druckplatte beim Auskuppeln ist die Verwendung einer Kupplungsfeder mit degressiver Kennlinie bei einer herkömmlichen Lamellenkupplung aber nicht möglich. Bei einer im Betätigungsbereich degressiven Feder kommt es nämlich zu einer Verstärkung der Schiefstellung der Druckplatte, da die stärker durchgedrückte Seite der Feder mit einer geringeren Gegenkraft reagiert. Die starke Schiefstellung der Druckplatte bewirkt eine erhebliche Verschlechterung des Trennverhaltens der Kupplung. Für den Fahrer macht sich das in einem lauten Einlegegeräusch des ersten Ganges, lauten Schaltgeräuschen sowie in einer schlechten Auffindbarkeit des Leerlaufes bemerkbar. Des weiteren neigt eine derart schlecht trennende Kupplung mit infolge der schief stehenden Druckplatte taumelnden Kupplungslamellen zu starkem Rupfen.In high power motorcycles, the manual force required to disengage, which the driver must exert on the clutch lever, can be substantial. When using a diaphragm spring with plateau-shaped spring characteristic, the hand force to be exerted on the clutch lever is constant over the entire actuating travel. To reduce the hand force required for disengaging and the work to be done, the use of a diaphragm spring with a degressive from the operating point in the direction of actuation characteristic is proposed. By this falling characteristic can be reduced in a cost effective manner, the work required to open the clutch because the manual force decreases over the path of the clutch lever. This means a significant gain in comfort for the driver. Because of the eccentric loading of the pressure plate during disengagement for the reasons mentioned above, the use of a clutch spring with degressive characteristic in a conventional multi-plate clutch but not possible. In the case of a degressive spring in the actuation area, an increase in the misalignment of the pressure plate occurs, since the more strongly compressed side of the spring reacts with a smaller counterforce. The strong misalignment of the pressure plate causes a significant deterioration of the separation behavior of the clutch. For the driver this is noticeable in a loud inserting noise of the first gear, loud switching noises as well as in a poor findability of the idling. Furthermore, such a poorly separating clutch tends to pluck with wobble due to the tilted pressure plate clutch plates.
Wegen der unvermeidbaren Bauteiltoleranzen besteht auch ein gewisses radiales Spiel, das eine Schiefstellung der Druckplatte ermöglicht. Der Erfindung liegt die Aufgabe zugrunde, die erfindungsgemäße Lamellenkupplung dahingehend zu verbessern, dass bei einer Betätigung eine Schiefstellung sowie eine exzentrische Krafteinleitung verhindert wird.Because of the unavoidable component tolerances there is also a certain radial play, which allows a misalignment of the pressure plate. The invention has for its object to improve the multi-plate clutch according to the invention to the extent that upon actuation a misalignment and an eccentric force is prevented.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass der Druckpilz mit einem Fortsatz versehen ist, der in einer Bohrung der Getriebeeingangswelle zu einer koaxialen Bewegung geführt ist. Durch diese Maßnahme ist gewährleistet, dass die Betätigungskraft konzentrisch in die Kupplung eingeleitet wird. Des weiteren wird eine Schiefstellung aufgrund weiterer Bauteiltoleranzen und radialer Spiele unterbunden. Die erfindungsgemäße Lamellenkupplung eignet sich daher zur Verwendung einer Membranfeder mit einer ab dem Betriebspunkt in Betätigungsrichtung fallenden Kennlinie. Eine solche Membranfeder bietet eine kostengünstige Möglichkeit der Verringerung der Kupplungshandkraft und damit einen deutlichen Komfortgewinn für den Fahrer. Mit dem in der Getriebeeingangswelle geführten Druckpilz wird auf effektive und kostengünstige Art und Weise eine Zentrierung der Druckplatte erreicht. Die erfindungsgemäße Maßnahme läßt sich in dem bestehenden Bauraum verwirklichen und bringt nur ein geringes Mehrgewicht mit sich.According to the invention this object is achieved in that the pressure fungus is provided with an extension which is guided in a bore of the transmission input shaft to a coaxial movement. This measure ensures that the actuating force is introduced concentrically into the coupling. Furthermore, a misalignment is prevented due to further component tolerances and radial games. The multi-plate clutch according to the invention is therefore suitable for use of a diaphragm spring with a falling from the operating point in the direction of actuation characteristic. Such a diaphragm spring offers a cost-effective way of reducing the clutch force and thus a significant gain in comfort for the driver. With the pressure mushroom guided in the transmission input shaft centering of the pressure plate is achieved in an effective and cost-effective manner. The inventive measure can be realized in the existing space and brings only a small extra weight with it.
Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention will be explained in more detail with reference to an embodiment shown in the drawing.
In der einzigen Figur der Zeichnung ist eine Lamellenkupplung im Längsschnitt schematisch dargestellt.In the single figure of the drawing, a multi-plate clutch is shown schematically in longitudinal section.
Die in der Zeichnung dargestellte Lamellenkupplung ist insbesondere zum Einsatz bei einem Motorrad bestimmt. Auf einer Getriebeeingangswelle 10 ist ein Zahnrad, das sogenannte Primärrad 11 mit einem Rollenlager drehbar gelagert. Das Primärrad 11 wird von der (nicht gezeigten) Kurbelwelle eines Verbrennungsmotors angetrieben. Mit dem Primärrad 11 ist ein Gehäuse, der sogenannte Korb 12 drehfest verbunden. Ein Mitnehmer 13 ist mit der Getriebeeingangswelle 10 dreh- und axialfest verbunden. Eine Druckplatte 14 ist mit dem Mitnehmer 13 drehfest, aber axial verschiebbar verbunden. Die Druckplatte 14 hat mehrere Dome 15, die sich zwischen den Speichen des Mitnehmers 13 axial erstrecken. Ein Drucktopf 16 ist mit der Druckplatte 14 starr verbunden. Genauer gesagt der Drucktopf 16 ist mit den Domen 15 verschraubt. Eine ringförmige Membranfeder 17 stützt sich am äußeren Umfangsbereich an dem Mitnehmer 13 und am inneren Umfangsbereich an dem Drucktopf 16 ab. Zwischen dem Mitnehmer 13 und der Druckplatte 14 ist ein Paket ringförmiger Kupplungslamellen 18 eingespannt. Hintereinander sind abwechselnd treibende und getriebene Lamellen 18 angeordnet. Die treibenden Lamellen sind an ihrem äußeren Umfang gezahnt. Ihre Zähne greifen in entsprechende Nuten des Kupplungskorbes 12 ein. Die getriebenen Lamellen greifen mit Zähnen in entsprechende Nuten des Mitnehmers 13 ein, der mit der Getriebeeingangswelle 10 dreh- und axialfest verbunden ist. Die Lamellen 18 sind in den zugeordneten Nuten des Korbes 12 bzw. des Mitnehmers 13 axial verschiebbar. Die Lamellen 18 laufen in einem Ölbad, weshalb man auch von einer Naßkupplung spricht. In eine zur Getriebeeingangswelle 10 konzentrische Öffnung des Drucktopfes 16 ist ein Ausrücklager 19 eingesetzt, das sich mit einem Ringflansch an dem Drucktopf 16 abstützt. In den Innenring des Ausrücklagers 19 ist ein zylindrischer Druckpilz 20 eingesetzt, der sich mit einem Ringflansch am Innenring abstützt.The multi-plate clutch shown in the drawing is intended in particular for use in a motorcycle. On a transmission input shaft 10, a gear, the so-called primary wheel 11 is rotatably mounted with a roller bearing. The primary wheel 11 is driven by the crankshaft (not shown) of an internal combustion engine. With the primary wheel 11 is a housing, the so-called basket 12 rotatably connected. A driver 13 is rotatably and axially fixed to the transmission input shaft 10. A pressure plate 14 is rotatably connected to the driver 13, but axially displaceably connected. The pressure plate 14 has a plurality of domes 15 extending axially between the spokes of the driver 13. A pressure pot 16 is with the pressure plate 14 rigidly connected. More specifically, the pressure pot 16 is bolted to the domes 15. An annular diaphragm spring 17 is supported on the driver 13 at the outer circumferential region and on the pressure pot 16 at the inner peripheral region. Between the driver 13 and the pressure plate 14, a package of annular clutch plates 18 is clamped. In succession, driving and driven blades 18 are arranged alternately. The driving lamellae are toothed on their outer periphery. Their teeth engage in corresponding grooves of the clutch basket 12. The driven blades engage with teeth in corresponding grooves of the driver 13, which is rotatably and axially fixed to the transmission input shaft 10. The fins 18 are axially displaceable in the associated grooves of the basket 12 and the driver 13. The fins 18 run in an oil bath, which is why one speaks of a wet clutch. In a concentric with the transmission input shaft 10 opening of the pressure pot 16, a release bearing 19 is inserted, which is supported with an annular flange on the pressure pot 16. In the inner ring of the release bearing 19, a cylindrical pressure mushroom 20 is inserted, which is supported with an annular flange on the inner ring.
Zum Unterbrechen des Kraftflusses von dem (nicht gezeigten) Verbrennungsmotor zu einem (gleichfalls nicht gezeigten) Wechselgetriebe, d. h. zum Öffnen der Kupplung wird in Axialrichtung eine durch einen Pfeil angedeutete Kraft auf den Druckpilz 20 ausgeübt. Diese Kraft wird über das Ausrücklager 19 und den Druckkopf 16 auf die Dome 15 übertragen, so dass sich die Druckplatte 14 nach links bewegt. Dadurch wird bewirkt, dass die Kraft der Membranfeder 17 nicht mehr auf die Lamellen 18 wirkt. Diese lösen sich dadurch voneinander, und die Kraftübertragung ist unterbrochen. Wenn die auf den Druckpilz 20 ausgeübte Kraft aufgehoben wird, dann bewegen sich der Druckkopf 16 und die damit verbundene Druckplatte 14 unter der Vorspannkraft der Membranfeder 17 nach rechts, so dass die Lamellen 18 zwischen der Druckplatte 14 und dem Mitnehmer 13 eingespannt sind und somit ein Drehmoment vom Primärrad 11 auf die Getriebeeingangswelle 10 übertragen werden kann.For interrupting the power flow from the internal combustion engine (not shown) to a change gear (also not shown), d. H. To open the clutch, a force indicated by an arrow is exerted on the pressure mushroom 20 in the axial direction. This force is transmitted via the release bearing 19 and the print head 16 to the dome 15, so that the pressure plate 14 moves to the left. This causes that the force of the diaphragm spring 17 no longer acts on the fins 18. As a result, they separate from each other and the power transmission is interrupted. When the force exerted on the mushroom 20 force is released, then move the print head 16 and the associated pressure plate 14 under the biasing force of the diaphragm spring 17 to the right, so that the fins 18 are clamped between the pressure plate 14 and the driver 13 and thus a Torque from the primary wheel 11 can be transmitted to the transmission input shaft 10.
Eine Lamellenkupplung mit dem vorstehend beschriebenen Aufbau ist allgemein bekannt, so dass eine nähere Erläuterung entbehrlich ist. Neuartig ist die Ausbildung und Lagerung des Druckpilzes 20. Dieser besitzt einen konzentrischen zylindrischen Fortsatz 21 , der in einer konzentrischen Bohrung 22 der Getriebeeingangswelle 10 zu einer axialen Verschiebung spielfrei geführt ist. Durch diese Führung des Druckpilzes 20 in der Getriebeeingangswelle 10 wird dreierlei erreicht. Einerseits wird die Druckplatte 14 zentriert und andererseits wird beim Öffnen der Kupplung eine konzentrische Einleitung der Ausrückkraft gewährleistet. Zum dritten wird eine direkte Einschränkung des Kippspiels bewirkt. Somit wird eine Schiefstellung der Druckplatte 14 zuverlässig verhindert. Dieser Umstand ermöglicht die Verwendung einer Membranfeder 17 mit einer ab dem Betriebspunkt in Betätigungsrichtung fallenden Kennlinie. Der Vorteil einer solchen Membranfeder besteht in der Reduzierung der Kupplungshandkraft und damit in einem Komfortgewinn für den Fahrer. Dadurch, dass eine Schiefstellung der Druckplatte 14 und damit der Lamellen 18 verhindert wird, werden Probleme, wie lautes Schaltgeräusch, insbesondere beim Einlegen des ersten Ganges, schlechte Auffindbarkeit des Leerlaufs oder Rupfen der Kupplung vermieden.A multi-plate clutch with the structure described above is well known, so that a more detailed explanation is unnecessary. Novel is the design and storage of the pressure fungus 20. This has a concentric cylindrical extension 21 which is guided in a concentric bore 22 of the transmission input shaft 10 to an axial displacement without play. Through this leadership of the pressure mushroom 20 in the transmission input shaft 10 three things is achieved. On the one hand, the pressure plate 14 is centered and on the other hand, a concentric initiation of the release force is ensured when opening the clutch. Third, a direct restriction of the tilting game is effected. Thus, a misalignment of the pressure plate 14 is reliably prevented. This circumstance allows the use of a diaphragm spring 17 with a falling from the operating point in the direction of actuation characteristic. The advantage of such a diaphragm spring is the reduction of the clutch force and thus in a comfort gain for the driver. The fact that a misalignment of the pressure plate 14 and thus of the fins 18 is prevented, problems such as loud switching noise, especially when inserting the first gear, poor findability of the idling or juddering of the clutch are avoided.
