Description

Elektrisch angetriebenes Gleiskettenfahrzeug Electrically powered caterpillar

Die Erfindung betrifft ein elektrisch angetriebenes Gleiskettenfahrzeug nach dem Oberbegriff des Hauptanspruchs .The invention relates to an electrically driven caterpillar vehicle according to the preamble of the main claim.

Aus der DE 100 55 27 AI ist ein solches elektrisch angetriebenes Gleiskettenfahrzeug bekannt . Es weist eine Fahrzeugwanne und Gleisketten auf, die auf zugeordnetenSuch an electrically driven caterpillar vehicle is known from DE 100 55 27 AI. It has a vehicle pan and caterpillars that are assigned to it

Laufwerken mit mehreren Rollen laufen und dabei von einem Triebkranz antreibbar sind. Jedem Triebkranz ist eine Antriebseinrichtung, bestehend aus zwei Elektromotoren und einem Verbindungsgetriebe, zugeordnet. Die Elektromotoren bei diesem bekannten Gleiskettenfahrzeug sind zwischen den beiden Gleisketten im Bereich der Fahrzeugmitte angeordnet, so dass dieser Bauraum nicht für andere Zwecke zur Verfügung steht .Running drives with several rollers and can be driven by a drive ring. A drive device consisting of two electric motors and a connecting gear is assigned to each drive ring. The electric motors in this known caterpillar vehicle are arranged between the two caterpillars in the area of the center of the vehicle, so that this installation space is not available for other purposes.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Gleiskettenfahrzeug anzugeben, bei dem im Bereich der Fahrzeugmitte zwischen den beiden Gleisketten ein breiterer freier Bauraum vorhanden ist, der nicht durch Antriebskomponenten belegt ist.The present invention is therefore based on the object of specifying a caterpillar vehicle in which there is a wider free space in the area of the vehicle center between the two caterpillar tracks, which is not occupied by drive components.

Erfindungsgemäß wird diese Aufgabe durch ein, auch die Merkmale des kennzeichnenden Teils des Hauptanspruchs aufweisendes Gleiskettenfahrzeug gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind durch die Unteransprüche ge- gebe .According to the invention, this object is achieved by a caterpillar vehicle which also has the features of the characterizing part of the main claim. Advantageous embodiments of the invention are given by the subclaims.

Erfindungsgemäß ist also der oder die Elektromotor (en) , zumindest teilweise, in dem von der Gleiskette eingenommenen axialen Bauraum oberhalb der Gleiskette angeordnet und das Verbindungsgetriebe ist auf der zur Fahrzeugmitte zugewandten Seite von Triebkranz und Antriebsmotor angeordnet, wobei das Gehäuse des Verbindungsgetriebes starr mit der Fahrzeugwanne verbunden ist. Es verbleibt ein breiter Bauraum in der Fahrzeugmitte.According to the invention, the electric motor (s) is, at least partially, in that of the track chain occupied axial space above the track and the connecting gear is arranged on the side facing the vehicle center of the driving ring and drive motor, the housing of the connecting gear being rigidly connected to the vehicle pan. There is a wide space in the middle of the vehicle.

Das Verbindungsgetriebe kann als Stirnräderkette oder auch als Umschlingungsgetriebe mit einem Ketten- oder Rie- mentrieb ausgebildet sein.The connecting gear can be designed as a spur gear chain or as a belt drive with a chain or belt drive.

Für höhere Leistungsanforderungen ist es auch möglich, ein Verbindungsgetriebe mit zwei Eingängen vorzusehen, denen jeweils ein Elektromotor zugeordnet ist, so dass die Leistung von zwei Elektromotoren auf einen Triebkranz wirkt .For higher power requirements, it is also possible to provide a connecting gear with two inputs, each of which is assigned an electric motor, so that the power of two electric motors acts on a drive ring.

Anhand der beiliegenden Figuren wird die Erfindung näher erläutert . Darin zeigenThe invention is explained in more detail with reference to the accompanying figures. Show in it

Fig. 1 eine schematische Draufsicht auf ein erfindungsgemäßes Gleiskettenfahrzeug undFig. 1 is a schematic plan view of an inventive caterpillar and

Fig. 2 eine schematische Seitenansicht desselben.Fig. 2 is a schematic side view of the same.

In Fig. 1 ist mit 2 die Fahrzeugwanne und mit 4 die linke und rechte Gleiskette des Gleiskettenfahrzeugs bezeichnet. Jeder Gleiskette 4 ist ein Triebkranz 6 mit darin befindlichem Seitenvorgelege zugeordnet. Der Triebkranz bzw. das Seitenvorgelege wird angetrieben von einem Verbindungsgetriebe 8, welches zwei Eingänge für Elektromotoren 10, 12 aufweist, deren Leistung das Verbindungsgetrie- be 8 summiert. Die Elektromotoren 10, 12 sind mit ihrem größten Teil im selben axialen Bauraum angeordnet, der von der Gleiskette eingenommen wird, und zwar oberhalb der Gleiskette (Fig. 2). Das Verbindungsgetriebe 8 ist auf der zur Fahrzeugmitte zugewandten Seite von Triebkranz 6 und Antriebsmotoren 10, 12 angeordnet, wobei das Gehäuse des Verbindungsgetriebes 8 starr mit der Fahrzeugwanne verbunden ist. Die Gleiskette 4 läuft auf Rollen 14 eines Gleiskettenlaufwerks .In Fig. 1, 2 denotes the vehicle trough and 4 denotes the left and right caterpillars of the caterpillar vehicle. Each crawler belt 4 is assigned a drive ring 6 with a side gear located therein. The driving ring or the countershaft is driven by a connecting gear 8, which has two inputs for electric motors 10, 12, the power of which is the connecting gear be 8 totaled. The majority of the electric motors 10, 12 are arranged in the same axial installation space that is occupied by the caterpillar track, namely above the caterpillar track (FIG. 2). The connecting gear 8 is arranged on the side of the drive ring 6 and drive motors 10, 12 facing the center of the vehicle, the housing of the connecting gear 8 being rigidly connected to the vehicle pan. The caterpillar track 4 runs on rollers 14 of a caterpillar track drive.

Im Bereich der Fahrzeugmitte zwischen den beiden Verbindungsgetrieben verbleibt ein breiter Durchgang bzw. ein breiter Bauraum, der frei von Antriebskomponenten ist. In the area of the center of the vehicle between the two connecting gears there remains a wide passage or a large installation space that is free of drive components.
