Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, ein Differenzialgetriebe anzugeben, welches eine Umschaltung zwischen einem Vorwärts- und einem Rückwärtsbetrieb ermöglicht.The invention has for its object to provide a differential gear, which allows a switch between a forward and a reverse operation.
Zusammenfassung der ErfindungSummary of the invention
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Differenzialgetriebe mit den Merkmalen des Anspruchs 1.This object is achieved by a differential gear with the features of
Das Differenzialgetriebe weist einen über eine Kegelradverzahnung angetriebenen Differentialkorb auf, welcher zwei Abtriebswellen mit zueinander variierbarer Drehzahl antreibt, wobei durch die Kegelradverzahnung zwei entgegengesetzt zueinander rotierende Zwischenräder angetrieben sind und der Differentialkorb über eine Schiebehülse wahlweise mit einem der Zwischenräder koppelbar ist.The differential gear has a driven via a bevel gear differential carrier, which drives two output shafts with mutually variable speed, being driven by the bevel gear two oppositely rotating intermediate wheels and the differential carrier via a sliding sleeve with either one of the intermediate wheels can be coupled.
Eine Umschaltung zwischen Vorwärts- und Rückwärtsbetrieb ist durch Verschieben der Schiebehülse möglich. In beiden Betriebsmodi weist das Differenzialgetriebe identische Leistungsdaten auf. Ein gesondertes Getriebe zur Umschaltung zwischen Vorwärtsgang und Rückwärtsgang ist nicht erforderlich. Bei der Welle, welche über die Kegelradverzahnung den Differentialkorb antreibt, handelt es sich zum Beispiel um eine Ausgangswelle eines hydrostatischen Getriebes. Ein bevorzugtes Anwendungsgebiet des Differenzialgetriebes sind landwirtschaftliche Maschinen, insbesondere Aufsitzgeräte zur Garten- und Landschaftspflege. Prinzipiell ist ein von einer Brennkraftmaschine angetriebenes Aufsitzgerät zur Garten- und Landschaftspflege zum Beispiel aus der
In einer bevorzugten Ausgestaltung ist die Rotationsachse der Zwischenräder mit der Rotationsachse des Differenzialkorbs, das heißt mit der Rotationsachse der Abtriebswellen, identisch. In besonders bevorzugter Weise überragen die Zwischenräder den Differentialkorb in radialer Richtung, bezogen auf die Rotationsachse der Abtriebswellen. In a preferred embodiment, the axis of rotation of the intermediate wheels with the axis of rotation of the differential cage, that is, with the axis of rotation of the output shafts, identical. In a particularly preferred manner, the intermediate wheels project beyond the differential carrier in the radial direction, relative to the axis of rotation of the output shafts.
Gemäß einer vorteilhaften Ausführungsform ist die Schiebehülse radial, bezogen auf die Rotationsachse der Abtriebswellen, außerhalb einer zylindrischen, mit einer mit der Schiebehülse zusammenwirkenden Verzahnung versehenen Mantelfläche des Differentialkorbs angeordnet, wobei die Rotationsachse der Abtriebswellen mit der Symmetrieachse der Schiebehülse identisch ist. Zur Herstellung einer Drehmoment übertragenden Verbindungen zwischen einem der Zwischenräder und dem Differentialkorb können zusätzlich zur Schiebehülse weitere in definierter Weise Kraft übertragende Elemente, wie zum Beispiel Synchronringe, vorgesehen sein.According to an advantageous embodiment, the sliding sleeve is arranged radially, relative to the axis of rotation of the output shafts, outside a cylindrical, provided with a sliding sleeve cooperating toothing lateral surface of the differential carrier, wherein the axis of rotation of the output shafts with the axis of symmetry of the sliding sleeve is identical. To produce a torque-transmitting connections between one of the intermediate wheels and the differential carrier, in addition to the sliding sleeve further in a defined manner force-transmitting elements, such as synchronizer rings may be provided.
In dem Differentialkorb ist ein Ausgleichsgetriebe, nämlich das Differenzial im engeren Sinne, eingebaut, welches als Kegelraddifferential oder als Stirnraddifferenzial ausgebildet sein kann.In the differential carrier is a differential gear, namely the differential in the strict sense, built-in, which may be formed as a bevel gear or spur gear differential.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand einer Zeichnung näher erläutert. Hierin zeigt:An embodiment of the invention will be explained in more detail with reference to a drawing. Hereby shows:
