Description
Die Erfindung betrifft eine Riemenscheibe für einen Riementrieb gemäß dem Oberbegriff des Anspruchs 1, sowie einen Riemenstarter für eine Brennkraftmaschine mit einer solchen Riemenscheibe gemäß dem Oberbegriff des Anspruchs 12.The invention relates to a belt pulley for a belt drive according to the preamble of claim 1, and to a belt starter for an internal combustion engine with such a belt pulley according to the preamble of
Hybridantriebe von Kraftfahrzeugen umfassen als Fahrantrieb neben einer Brennkraftmaschine entweder eine oder zwei elektrische Maschinen. Dort, wo nur eine elektrische Maschine als Fahrantrieb vorgesehen ist, wird diese elektrische Maschine häufig auch als Starter für die Brennkraftmaschine genutzt. In diesem Fall muss jedoch ein Teil der Leistung der elektrischen Maschine für den Startvorgang vorgehalten werden, um die Brennkraftmaschine während des rein elektrischen Fahrbetriebs starten zu können, ohne dass es zu einem für den Benutzer spürbaren ruckartigen Drehmomentabfall kommt. Dies führt jedoch im elektrischen Fahrbetrieb zu einer von Seiten des Benutzers unerwünschten spürbaren Einschränkung der Fahrleistung.Hybrid drives of motor vehicles comprise as drive in addition to an internal combustion engine either one or two electric machines. Where only an electric machine is provided as a drive, this electric machine is often used as a starter for the internal combustion engine. In this case, however, a part of the power of the electric machine for the starting process must be kept in order to start the engine during the purely electric driving operation, without resulting in a noticeable to the user jerky torque drop. However, this leads to an undesirable on the part of the user noticeable restriction of driving performance in electric driving.
Um dieses Problem zu lösen, wurde bereits vorgeschlagen, neben der als Fahrantrieb dienenden elektrischen Maschine des Hybridantriebs eine kleinere elektrische Maschine vorzusehen, die nur als Starter zum Starten der Brennkraftmaschine dient. Diese elektrische Maschine könnte zwar grundsätzlich von einem herkömmlichen Serienstarter gebildet werden, dessen Ritzel mit einer Verzahnung eines Schwungrades der Brennkraftmaschine in Eingriff gebracht wird. Da die Montage eines derartigen Starters bei Hybridantrieben zum Beispiel auf Grund von Bauraumproblemen jedoch nicht immer möglich ist und da bei Verwendung eines derartigen Starters zudem der Start zu lange dauert, wurde daran gedacht, einen Riemenstarter zu verwenden, bei dem der Startermotor die Kurbelwelle über einen Riementrieb andreht. Um zu vermeiden, dass bei laufender Brennkraftmaschine der Riementrieb mitläuft, was zu einer Erhöhung des Kraftstoffverbrauchs der Brennkraftmaschine und einer verschleißbedingten Verringerung der Lebensdauer des Riementriebs führt, muss jedoch eine Kupplung vorgesehen werden, die den Riementrieb bei laufender Brennkraftmaschine von der Kurbelwelle abkoppelt. Grundsätzlich könnte eine solche Kupplung zwischen der Kurbelwelle und der Riemenscheibe des Riementriebs vorgesehen und zum Beispiel als Magnetkupplung ausgebildet werden. Eine derartige Kupplung ermöglicht zwar ein dynamisches Abkuppeln der Riemenscheibe, hat jedoch insofern Nachteile, als sie eine große Baulänge und ein verhältnismäßig großes Gewicht besitzt und einen zusätzlichen elektrischen Anschluss benötigt. Weiter muss zwischen dem Riementrieb und der Kurbelwelle zur Schwingungsentkopplung auch ein Torsionsschwingungsdämpfer vorgesehen werden, der die Bauraumprobleme weiter verschärft, so dass es von Vorteil wäre, die Kupplung und den Torsionsschwingungsdämpfer in die Riemenscheibe zu integrieren.In order to solve this problem, it has already been proposed to provide, in addition to the electrical drive of the hybrid drive serving as a traction drive, a smaller electrical machine which serves only as a starter for starting the internal combustion engine. Although this electric machine could in principle be formed by a conventional series starter whose pinion is brought into engagement with a toothing of a flywheel of the internal combustion engine. However, since the assembly of such a starter in hybrid drives, for example, due to space problems is not always possible and since the start takes too long when using such a starter, it was thought to use a belt starter, wherein the starter motor, the crankshaft via a Belt drive turns on. However, in order to avoid that the belt drive runs with the internal combustion engine running, which leads to an increase in the fuel consumption of the internal combustion engine and a wear-related reduction in the service life of the belt drive, a clutch must be provided which decouples the belt drive from the crankshaft when the internal combustion engine is running. In principle, such a coupling between the crankshaft and the belt pulley of the belt drive could be provided and formed, for example, as a magnetic coupling. Although such a coupling allows a dynamic uncoupling of the pulley, but has disadvantages in that it has a large overall length and a relatively large weight and requires an additional electrical connection. Furthermore, a torsional vibration damper must be provided between the belt drive and the crankshaft for vibration decoupling, which further aggravates the installation space problems, so that it would be advantageous to integrate the clutch and the torsional vibration damper into the belt pulley.
Aus der
Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, eine Riemenscheibe und einen Riemenstarter der eingangs genannten Art dahingehend zu verbessern, dass die Riemenscheibe als Teil eines Riementriebs zwischen einem Startermotor und der Kurbelwelle einsetzbar ist, um bei laufender Brennkraftmaschine den Riementrieb von der Kurbelwelle der Brennkraftmaschine abzukuppeln.Proceeding from this, the present invention seeks to improve a pulley and a belt starter of the type mentioned in that the pulley is used as part of a belt drive between a starter motor and the crankshaft to decouple the belt drive from the crankshaft of the internal combustion engine while the engine is running ,
Diese Aufgabe wird im Hinblick auf die Riemenscheibe erfindungsgemäß dadurch gelöst, dass der Riemenscheibenring die Nabe treibt und dass die Freilaufkupplung öffnet, wenn die Nabe den Riemenscheibenring überholt.This object is achieved in terms of the pulley according to the invention in that the pulley ring drives the hub and that the overrunning clutch opens when the hub overtakes the pulley ring.
Eine bevorzugte Ausgestaltung der Erfindung sieht vor, dass die Freilaufkupplung eine Mehrzahl von federbelasteten Klemmkörpern umfasst, die zwischen der Nabe und dem Riemenscheibenring angeordnet sind und in geschlossenem Zustand der Freilaufkupplung infolge der Federbelastung gegen den Riemenscheibenring und die Nabe angepresst werden, während sie in geöffnetem Zustand der Kupplung vom Riemenscheibenring abgehoben sind.A preferred embodiment of the invention provides that the overrunning clutch comprises a plurality of spring-loaded clamping bodies, which are arranged between the hub and the pulley ring and pressed in the closed state of the overrunning clutch due to the spring load against the pulley ring and the hub, while in the open state the coupling are lifted from the pulley ring.
Um zu gewährleisten, dass sich die in geöffnetem Zustand der Kupplung vom Riemenscheibenring abgehobenen federbelasteten Klemmkörper mit der Nabe mitdrehen, weist die Freilaufkupplung vorteilhaft einen drehfest mit der Nabe verbundenen Außenring, einen Innenring und mindestens einen Freilaufkäfig auf, welche die Klemmkörper schwenkbar aufnehmen.In order to ensure that rotate in the open state of the clutch lifted from the pulley ring spring-loaded clamping body with the hub, the overrunning clutch advantageously has a non-rotatably connected to the hub outer ring, an inner ring and at least one freewheel cage, which receive the clamping body pivotally.
Zur Zentrierung des Riemenscheibenrings in Bezug zur Nabe bei abgehobenen Klemmkörpern sowie zur drehbaren Lagerung des Riemenscheibenrings auf der Nabe dient vorteilhaft ein zwischen der Nabe und dem Riemenscheibenring angeordnetes Wälzlager, das zweckmäßig radial einwärts von der Freilaufkupplung angeordnet ist.For centering the pulley ring with respect to the hub with lifted sprags and for rotatably supporting the pulley ring on the hub advantageously serves a arranged between the hub and the pulley ring rolling bearing, which is expediently arranged radially inwardly of the one-way clutch.
Der Torsionsschwingungsdämpfer umfasst vorzugsweise einen Schwungring, der über ein Elastomermaterial mit der Nabe verbunden ist. Um die Masse des Schwungrings zu minimieren, ist der Torsionsschwingungsdämpfer vorzugsweise radial auswärts von der Freilaufkupplung angeordnet, wobei er zweckmäßig mit einem allgemein zylindrischen Abschnitt der Nabe verbunden ist, der in den im Querschnitt U-förmigen Riemenscheibenring ragt. The torsional vibration damper preferably includes a flywheel ring connected to the hub via an elastomeric material. In order to minimize the mass of the flywheel, the torsional vibration damper is preferably located radially outward of the one-way clutch, being suitably connected to a generally cylindrical portion of the hub which projects into the U-shaped pulley ring.
Im Hinblick auf den Riemenstarter sieht die Erfindung vor, dass der Riementrieb eine Riemenscheibe, wie zuvor beschrieben umfasst, wobei der Riemenscheibenring über die Nabe die Kurbelwelle der Brennkraftmaschine andreht, und wobei die Freilaufkupplung öffnet, wenn die Kurbelwelle den Riemenscheibenring überholt.With regard to the belt starter, the invention provides that the belt drive comprises a pulley as described above, wherein the pulley ring rotates the crankshaft of the engine via the hub, and wherein the overrunning clutch opens when the crankshaft overrides the pulley ring.
