Abstract
Description
Die vorliegende Erfindung betrifft eine Antriebsvorrichtung für Tandemachsen von Arbeitsmaschinen, insbesondere von Waldtraktoren, nach dem Oberbegriff des Schutzanspruches 1.The present invention relates to a drive device for tandem axles of work machines, especially of Forest tractors, according to the preamble of protection claim 1.
Beispielsweise geht aus der DE 41 20 801 A1 eine solche Antriebsvorrichtung für Tandemachsen hervor. Arbeitsma schinen, die mit solchen Tandemachsen ausgerüstet sind, werden vorwiegend im schwierigen Gelände verwendet, wobei die Kraftübertragung gleichmäßig auf die Vorder- und Hin terräder einer Seite einer Tandemachse eingeleitet wird.For example, one such from DE 41 20 801 A1 Drive device for tandem axles. Working machines equipped with such tandem axles, are mainly used in difficult terrain, whereby the power transmission evenly to the front and back Terra wheels on one side of a tandem axle is initiated.
Bei der DE 41 20 801 A1 erfolgt die Momentenübertragung im Tandem mit Zahnrädern. Dabei verläuft vom Vorderteil dis Antriebsfahrzeuges, das mittels eines Knickgelenkes mit dem hinteren Rahmen gelenkig verbunden ist, eine Kardanwelle zum Hinterrahmen, die an der Übergangsstelle zwischen Fahr zeugvorderteil und Hinterrahmen ebenfalls gelenkig ausge bildet ist. Die Kardanwelle steht in Verbindung mit einem in einem Differentialgehäuse gelagerten Differential, wobei sich links und rechts vom Differential Bremsen befinden. Die Kraftübertragung zu den beiden Tandemachsen eines Tan dems erfolgt über eine Treibwelle, die mit dem Differential verbunden ist. Die Treibwelle ist mit einem Stirnrad ver bunden, das in dem Tandemgehäuse des Tandems drehbar gela gert ist. Dieses Stirnrad steht über weitere im Tandemge häuse drehbar gelagerte Zahnräder eines Zahnradantriebes, die miteinander kämmen und die Antriebsvorrichtung bilden, zur Kraftübertragung vom Stirnrad hin zu den Planetenend stufen in Verbindung.In DE 41 20 801 A1 the torque transmission takes place in the Tandem with gears. Here runs from the front part dis Drive vehicle that by means of an articulated joint with the rear frame is articulated, a propeller shaft to the rear frame, which is at the transition point between driving front and rear frame also articulated forms is. The cardan shaft is connected to a differential stored in a differential case, wherein are to the left and right of the differential brakes. The power transmission to the two tandem axles of a tan dems done via a drive shaft that with the differential connected is. The drive shaft is ver with a spur gear bound, the rotatable gela in the tandem housing of the tandem device. This spur gear is in tandem with others Gear wheels of a gear drive that are rotatably mounted on the housing, which mesh with each other and form the drive device, for power transmission from the spur gear to the planet end stage in connection.
Ein Problem derartiger Antriebsvorrichtungen mit Zahnrädern besteht darin, daß sie relativ teuer sind.A problem with such drive devices with gears is that they are relatively expensive.
Es sind auch Antriebsvorrichtungen für Tandemachsen be kannt, bei denen die Momentenübertragung im Tandem durch Ketten erfolgt, wobei jedoch ein Problem besteht, daß die Ketten relativ leicht reißen können.There are also drive devices for tandem axles knows, where the torque transmission through in tandem Chains occur, but there is a problem that the Chains can tear relatively easily.
Die Aufgabe der vorliegenden Erfindung besteht daher darin, eine vergleichsweise kostengünstige Antriebsvorrichtung für Tandemachsen von Arbeitsmaschinen, insbesondere Waldtrakto ren, zu schaffen.The object of the present invention is therefore to a comparatively inexpensive drive device for Tandem axles of work machines, especially forest tractors ren to create.
Diese Aufgabe wird durch eine Antriebsvorrichtung mit den Merkmalen des Schutzanspruches 1 gelöst.This task is performed by a drive device with the Features of the protection claim 1 solved.
Der wesentliche Vorteil der erfindungsgemäßen Antriebsvor richtung besteht darin, daß sie anstelle der bekannten Zahnradketten zur Kraftübertragung im Tandem Antriebswellen verwenden, die relativ kostengünstig sind und zudem auch vorteilhafterweise eine große Lebensdauer aufweisen.The main advantage of the drive according to the invention direction is that instead of the known Gear chains for power transmission in tandem drive shafts use that are relatively inexpensive and also advantageously have a long service life.
Vorteilhafte Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor.Advantageous embodiments of the invention are shown in the Sub-claims emerge.
Im folgenden werden die Erfindung und deren Ausgestaltung im Zusammenhang mit den Figuren näher erläutert. Es zeigen: The invention and its configuration are described below explained in connection with the figures. Show it:
Fig. 1 in schematischer Darstellung eine Aufsicht auf eine erfindungsgemäße Antriebsvorrichtung für Tandemachsen und Fig. 1 shows a schematic representation of a top view of a drive device for tandem axles and
Fig. 2 eine Seitenansicht der erfindungsgemäßen Antriebs vorrichtung für die Tandemachsen der Fig. 1. Fig. 2 is a side view of the inventive drive device for tandem axles FIG. 1.
Der in Fig. 1 schematisch dargestellte Hinterrahmen 1 ist über ein nicht gezeigtes Knickgelenk mit dem eigentlichen Fahrzeug verbunden. Eine Kardanwelle 2 steht dabei mit dem in einem Differentialgehäuse 3 gelagerten Differential in Verbindung. Links und rechts vom Differentialgehäuse 3 sind Bremsen 4 angeordnet. Jede Treibwelle 5 treibt über eine Antriebsvorrichtung 6 ein Rad 7 des Tandems an. In jedem Tandemgehäuse 8 sind ein Vorder- und ein Hinterrad 7 ange ordnet.The rear frame 1 shown schematically in Fig. 1 is connected via an unshown pivot with the actual vehicle. A cardan shaft 2 is connected to the differential mounted in a differential housing 3 . Brakes 4 are arranged to the left and right of the differential housing 3 . Each drive shaft 5 drives a wheel 7 of the tandem via a drive device 6 . In each tandem housing 8 , a front and a rear wheel 7 are arranged.
Im wesentlichen umfaßt die vorliegende Antriebsvorrichtung 6 gemäß den Fig. 1 und 2 ein am Tandemgehäuse 8 gelager tes Kegelrad 10, das mit der Treibwelle 5 in Verbindung steht und vom Differential her angetrieben wird. Eine Welle 11 weist an ihren beiden Enden jeweils ein Kegelrad 12, 13 auf und ist im Tandemgehäuse 8 drehbar gelagert. Das Kegel rad 10 kämmt mit dem am einen Ende der Welle 11 befindli chen Kegelrad 12. Das am anderen Ende der Welle 11 befind liche Kegelrad 13 kämmt mit einem weiteren Kegelrad 14, das mit der Radachse 9 in Verbindung steht. Essentially, the present drive device 6 according to FIGS. 1 and 2 comprises a bevel gear 10 mounted on the tandem housing 8 , which is connected to the drive shaft 5 and is driven by the differential. A shaft 11 has a bevel gear 12 , 13 at its two ends and is rotatably supported in the tandem housing 8 . The bevel gear 10 meshes with the bevel gear 12 located at one end of the shaft 11 . The bevel gear 13 located at the other end of the shaft 11 meshes with a further bevel gear 14 which is connected to the wheel axle 9 .
