Abstract
Description
Die Erfindung bezieht sich auf eine mechanische ein- und ausrückbare Kupplung zur wahlweisen Übertragung eines auf eine drehbare Antriebsachse wirkenden Drehmomentes, von dem das Drehmoment auf eine in axialer Verlängerung angeordnete drehbare Abtriebsachse übertragen wird.The invention relates to a mechanical clutch engageable and disengageable for selectively transmitting a torque acting on a rotatable drive shaft, from which the torque is transmitted to a rotatable output shaft disposed in the axial extension.
Derartige Kupplungen werden zum Beispiel in Automobilen verwendet, um das von dem betreffenden Motor abgegebene Drehmoment wahlweise auf die Antriebsräder des Fahrzeugs zu übertragen. Diese Kupplungen sind üblicherweise Scheibenkupplungen, in denen zueinander passende Scheiben zum Einkuppeln zusammengepresst oder zum Auskuppeln voneinander entfernt werden. Dazwischen gibt es einen durch unterschiedliche Reibung bestimmten Mitnahmebereich, wobei die beiden Kupplungsteile mehr oder minder stark gegeneinander gepresst werden. Typisch für derartige Kupplungen ist die Übergangsfunktion vom Zustand des Auskuppelns zum Zustand des Einkuppelns, in dem die beiden Kupplungsteile mit ihren aufeinander aufliegenden Kupplungsflächen gegenseitig mehr oder minder stark schleifen, wodurch beim Einkuppelvorgang eine stufenlose Mitnahme des anzutreibenden Teils ermöglicht wird.Such clutches are used, for example, in automobiles to selectively transmit the torque output by the engine concerned to the drive wheels of the vehicle. These clutches are usually disc clutches in which mating discs are pressed together for engagement or removed from each other for disengaging. In between there is a driving range determined by different friction, wherein the two coupling parts are pressed against each other more or less strongly. Typical of such couplings is the transition function from the state of disengagement to the state of engagement, in which the two coupling parts with their superimposed coupling surfaces mutually more or less sharpen, which during engagement is a stepless entrainment of the driven part allows.
Im Gegensatz dazu handelt es sich bei der erfindungsgemäßen Kupplung um eine solche, die ohne irgendeinen Zwischenbereich ein- oder ausrückbar ist, d. h. entweder überträgt die Kupplung kein Drehmoment oder das auf die Antriebsachse der Kupplung wirkende Drehmoment wird voll auf die Abtriebsachse übertragen. Bei der erfindungsgemäßen Kupplung handelt es sich also um eine solche, die wie ein Schalter ein Drehmoment überhaupt nicht oder vollständig überträgt.In contrast, the coupling according to the invention is one which can be engaged or disengaged without any intermediate region, ie. H. either the clutch does not transmit torque or the torque acting on the drive axle of the clutch is fully transmitted to the output axle. The coupling according to the invention is therefore one which, like a switch, does not transmit torque completely or completely.
Der Erfindung liegt die Aufgabe zugrunde, eine derartige nur ein- und ausrückbare Kupplung zu schaffen, die besonders raumsparend gestaltet ist und eine Drehmomentübertragung zwischen einer Antriebsachse und einer Abtriebsachse mit großer Sicherheit überträgt. Gelöst wird das Problem dadurch, dass die eine Achse mit axialen Federzungen versehen ist, die in axiale Nuten der anderen Achse axial ein- oder ausschiebbar sind, wobei in eingeschobener Lage sich die Federzungen an die Wände der Nuten kraftübertragend anlegen.The invention has for its object to provide such only engageable and disengageable coupling, which is designed to save space and transmits a torque transmission between a drive axle and a driven axle with great certainty. The problem is solved in that the one axis is provided with axial spring tongues, which are axially in or out of axial grooves of the other axis, wherein in the inserted position, the spring tongues create a force-transmitting to the walls of the grooves.
Aufgrund dieser Gestaltung der Kupplung unter direkter Einbeziehung der Antriebsachse und der Abtriebsachse wird der von den Achsen sowieso erfüllte Raum auch für die Gestaltung der Kupplung ausgenutzt, so dass durch die Kupplung praktisch räumlich keine Erweiterung der aus Antriebs- und Abtriebsachse bestehenden Baugruppe entsteht, was für viele Anwendungsteile von entscheidender Bedeutung ist.Due to this design of the coupling with direct inclusion of the drive axle and the output shaft of the axles anyway filled space is also exploited for the design of the clutch, so that virtually no expansion of the existing drive and output shaft assembly arises due to the coupling, which for many application parts is crucial.
Durch die Verwendung von Federzungen zusammen mit den in dieser einrastenden Nuten ist es möglich, die Kupplung bei einem Überdrehmoment ausrasten zu lassen. Dies geschieht einfach dadurch, dass die Federzungen aufgrund starken seitlichen Druckes nach außen nachgeben, ausrasten und damit die Kupplung lösen.Through the use of spring tongues together with the engaging in this grooves, it is possible to disengage the clutch at a torque over. This is done simply by the fact that the spring tongues give way to the outside due to strong lateral pressure, disengage and thus release the clutch.
Um den Vorgang des Ausrastens der Federzungen zu erleichtern, gestaltet man die Nuten jeweils zweckmäßig so, dass sie in einer Rundung in die Wände zwischen den Nuten übergehen.In order to facilitate the process of disengaging the spring tongues, the grooves are each designed appropriately so that they pass in a rounding in the walls between the grooves.
Je nach Stärke des zu übertragenden Drehmomentes kann man die Zahl der Federzungen und oder deren Querschnitt entsprechend wählen, d. h. es ist möglich, weniger Federzungen vorzusehen, als Nuten vorhanden sind.Depending on the strength of the torque to be transmitted you can choose the number of spring tongues and or their cross section accordingly, d. H. It is possible to provide fewer spring tongues than grooves are present.
Um die Nuten und die Federzungen hinsichtlich ihrer Kraftübertragung voll auszunutzen, gestaltet man die Federzungen zweckmäßig so, dass sie im Wesentlichen über die gesamte Länge der Nuten reichen.To fully exploit the grooves and the spring tongues with regard to their power transmission, the spring tongues are expediently designed so that they extend substantially over the entire length of the grooves.
Die Länge der Nuten kann länger sein als der Einschubbereich der Federzungen. Die Antriebsachse und Abtriebsachse können jeweils mit besonderen Antriebs- und Abtriebselementen versehen sein. Gemäß einem Ausführungsbeispiel sind sowohl Antriebsachse als auch Abtriebsachse jeweils mit einem Zahnrad versehen, wobei dann von diesen Zahnrädern aus die Antriebs- bzw. Abtriebskraft übertragen wird. Selbstverständlich können die Antriebsachse und die Abtriebsachse auch mit beliebig anderen Bauelementen verbunden werden. Ein weiteres Ausführungsbeispiel zeigt die mit einem Bit versehene Abtriebsachse.The length of the grooves may be longer than the insertion area of the spring tongues. The drive axle and output shaft can each be provided with special drive and output elements. According to one embodiment, both drive axle and driven axle are each provided with a gear, in which case the drive or output power is transmitted from these gears. Of course, the drive axle and the output shaft can also be connected to any other components. Another embodiment shows the one-bit output axis.
