Abstract
Description
Erfindungsgemäß wird vorgeschlagen, auf die bisher eingesetzten Bauteile Sprengring und Haltering zu verzichten, mit denen bisher ein Ritzel, insbesondere ein Andrehritzel einer als Startvorrichtung ausgebildeten elektrischen Maschine gesichert war. Der erfindungsgemäß vorgeschlagenen Lösung folgend, wird eine geteilt ausgebildete Haltescheibe im Hinterschnitt des Andrehritzels platziert und ein vom Ritzel getrennter Rollenbund eingesetzt. Die Fixierung des Andrehritzels erfolgt bei der erfindungsgemäß vorgeschlagenen Lösung bei der Montage des Freilaufs durch die geteilt ausgebildete Haltescheibe in axiale Richtung. Eine Feder oder ein Federelement, welche das Starterritzel beaufschlagen, ist aufgrund des innenliegenden Einbaus vor zu hohen Fliehkräften geschützt. Das Andrehritzel stellt gegenüber dem Rollenbund ein separates Bauteil dar, welche innerhalb eines axialen Spiels relativ zueinander verschiebbar sind. Die Drehmomentübertragung erfolgt bei der erfindungsgemäß vorgeschlagenen Lösung, beispielsweise durch eine Klauenkupplung, oder eine andere formschlüssige Ausführung, so zum Beispiel einen Innensechsrund.According to the invention it is proposed to dispense with the previously used components snap ring and retaining ring with which previously a pinion, in particular a starter pinion of a trained as a starting device electrical machine was secured. Following the proposed solution according to the invention, a split formed holding disc is placed in the undercut of Andrehritzels and used a separated from the pinion roller collar. The fixation of the Andrehritzels takes place in the proposed solution according to the invention in the assembly of the freewheel through the split formed retaining disc in the axial direction. A spring or a spring element, which act on the starter pinion, is protected due to the internal installation from excessive centrifugal forces. The starter pinion is compared to the roller collar is a separate component, which are displaceable relative to each other within an axial clearance. The torque transmission takes place in the solution proposed by the invention, for example by a dog clutch, or another form-fitting design, such as a hexalobular.
Den Einsatzerfordernissen angepasst, können zur Herstellung des Rollenbundes und zur Herstellung des Andrehritzels jeweils verschiedene Materialien eingesetzt werden. So kann zum Beispiel der Rollenbund aus einem druckfesten Material gefertigt werden, welches den auftretenden Hertzschen Pressungen widersteht, während das Andrehritzel, welches ein vom Rollenbund separiertes Bauteil darstellt aus einem Sintermaterial oder sogar aus einem Kunststoffmaterial hergestellt werden kann. Die beiden separaten Teile können aus unterschiedlichen Herstell- und Härteverfahren stammen und daher optimal auf die jeweils auftretenden mechanischen Belastungen abgestimmt werden. Für die Erstellung einer neuen Freilaufvariante zum Einsatz in der Startvorrichtung mit einer andersartigen Verzahnung, was applikationsabhängig sein kann, ist der erfindungsgemäß vorgeschlagenen Lösung lediglich das Andrehritzel auszutauschen.Adapted to the requirements of the application, different materials can be used to produce the roll covenant and for the production of the turntable be used. Thus, for example, the roll collar can be made of a pressure-resistant material which resists the occurring Hertzian compressions, while the starter pinion, which is a component separated from the roll collar, can be made of a sintered material or even of a plastic material. The two separate parts can come from different manufacturing and hardening processes and are therefore optimally matched to the mechanical loads that occur in each case. For the preparation of a new freewheel variant for use in the starting device with a different type of toothing, which may be application-dependent, the proposed solution according to the invention is only to replace the starting pinion.

Ausführungsformen der ErfindungEmbodiments of the invention
In der
Der Startermotor 13 weist als Gehäuse ein Polrohr 28 auf, das an seinem Innenumfang Polschuhe 31 trägt, die jeweils von einer Erregerwicklung 34 umwickelt sind. Die Polschuhe 31 umgeben wiederum einen Anker 37, der ein aus Lamellen 40 aufgebautes Ankerpaket 43 und eine in Nuten 46 angeordnete Ankerwicklung 49 aufweist. Das Ankerpaket 43 ist auf eine Antriebswelle 44 aufgepresst. An dem dem Andrehritzel 22 abgewandten Ende der Antriebswelle 44 ist des Weiteren ein Kommutator 52 angebracht, der unter anderem aus einzelnen Kommutatorlamellen 55 aufgebaut ist. Die Kommutatorlamellen 55 sind in bekannter Weise mit der Ankerwicklung 49 derartig elektrisch verbunden, dass sich bei Bestromung der Kommutatorlamellen 55 durch Kohlebürsten 58 eine Drehbewegung des Ankers 37 im Polrohr 28 einstellt. Eine zwischen dem Vorspuraktuator 16 und dem Startermotor 13 angeordnete Stromzuführung 61 versorgt im Einschaltzustand sowohl die Kohlebürsten 58 als auch die Erregerwicklung 34 mit Strom. Die Antriebswelle 44 ist kommutatorseitig mit einem Wellenzapfen 64 in einem Gleitlager 67 abgestützt, das wiederum in einem Kommutatorlagerdeckel 70 ortsfest gehalten ist. Der Kommutatorlagerdeckel 70 wiederum wird mittels Zugankern 73, die über den Umfang des Polrohrs 28 verteilt angeordnet sind und zum Beispiel als 2, 3 oder 4 Schrauben ausgebildet sein können, im Antriebslagerschild 19 befestigt. Es stützt sich dabei das Polrohr 28 am Antriebslagerschild 19 ab und der Kommutatorlagerdeckel 70 am Polrohr 28.The
In Antriebsrichtung schließt sich an den Anker 37 ein Sonnenrad 80 an, welches Teil eines Umlaufgetriebes, so z.B. eines Planetengetriebes 83 ist. Das Sonnenrad 80 ist von mehreren Planetenrädern 86 umgeben, üblicherweise drei Planetenräder 86, die mittels Wälzlagern 89 auf Achszapfen 92 abgestützt sind. Die Planetenräder 86 wälzen in einem Hohlrad 95 ab, das im Polrohr 28 außenseitig gelagert ist. In Richtung zur Abtriebsseite hin schließt sich an die Planetenräder 86 ein Planetenträger 98 an, in dem die Achszapfen 92 aufgenommen sind. Der Planetenträger 98 wird wiederum in einem Zwischenlager 101 und einem darin angeordneten Gleitlager 104 gelagert. Das Zwischenlager 101 ist derartig topfförmig konfiguriert, dass in diesem sowohl der Planetenträger 98 als auch die Planetenräder 86 aufgenommen sind. Des Weiteren ist im topfförmigen Zwischenlager 101 das Hohlrad 95 angeordnet, das letztlich durch einen Deckel 107 gegenüber dem Anker 37 geschlossen ist. Auch das Zwischenlager 101 stützt sich mit seinem Außenumfang an der Innenseite des Polrohrs 28 ab. Der Anker 37 weist auf dem vom Kommutator 52 abgewandten Ende der Antriebswelle 44 einen weiteren Wellenzapfen 110 auf, der ebenfalls in einem Gleitlager 113 aufgenommen ist. Das Gleitlager 113 wiederum ist in einer zentralen Bohrung des Planetenträgers aufgenommen. Der Planetenträger 98 ist einstückig mit der Abtriebswelle 116 verbunden. Die Abtriebswelle 116 ist mit ihrem vom Zwischenlager 101 abgewandten Ende 119 in einem weiteren Lager 122, welches im Antriebslagerschild 19 befestigt ist, abgestützt. Die Abtriebswelle 116 ist in verschiedene Abschnitte aufgeteilt: So folgt dem Abschnitt, der im Gleitlager 104 des Zwischenlagers 101 angeordnet ist, ein Abschnitt mit einer Geradverzahnung 125 (Innenverzahnung), die Teil einer Wellen-Nabe-Verbindung 128 ist. Diese Wellen-Nabe-Verbindung 128 ermöglicht in diesem Falle das axial geradlinige Gleiten eines Mitnehmers 131. Der Mitnehmer 131 ist als hülsenartiger Fortsatz ausgebildet, der einstückig mit einem topfförmigen Außenring 132 des Freilaufes 137 ausgebildet ist. Dieser Freilauf 137 (Richtgesperre) besteht des Weiteren aus einem Innenring 140, der radial innerhalb des Außenringes 132 angeordnet ist. Zwischen dem Innenring 140 und dem Außenring 132 sind Klemmkörper 138 angeordnet. Die Klemmkörper 138 verhindern in Zusammenwirkung mit dem Innenring 140 und dem Außenring 132 eine Relativdrehung zwischen dem Außenring 132 und dem Innenring 140 in eine zweite Richtung. Mit anderen Worten: Der Freilauf 137 ermöglicht eine Relativbewegung zwischen dem Innenring 140 und dem Außenring 132 lediglich in eine Richtung. In diesem Ausführungsbeispiel ist der Innenring 140 einstückig mit dem Andrehritzel 22 und dessen Schrägverzahnung 143 (Außenschrägverzahnung) ausgeführt. Das Andrehritzel 22 kann alternativ auch als geradverzahntes Ritzel ausgeführt sein. Statt elektromagnetisch erregter Polschuhe 31 mit Erregerwicklung 34 könnten auch permanent magnetisch erregte Pole verwendet werden.In the drive direction, a sun gear 80 connects to the
