Diese Räumvorrichtung weist entgegen der Vortriebsrichtung rotierende Elemente auf und ist als Vorbaugerät für ein Fahrzeug, insbes . für ein Panzerfahrzeug, ausgebildet. Die rotierenden Elemente sind bei dieser bekannten Räumvorrichtung als Scheibenkörper ausgebildet, die wenigstens am Außenumfang Schneid- bzw. Sägeelemente aufweisen. Mehrere Scheibenkörper sind vertikal orientiert vorgesehen und nebeneinander angeordnet .DE 44 42 153 Cl discloses a clearing device for mines, grenades and other explosive bodies which are located in or on the ground.

Fig. 1 zeigt in einer Seitenansicht ein Minenräum-System 10 mit einemFig. 1 shows a side view of a mine clearance system 10 with a
Minenräumfahrzeug 12 und mit einem Minennachsuchfahrzeug 14. Das Minenräumfahrzeug 12 und das Minennachsuchfahrzeug 14 sind jeweils von einem modifizierten Panzerfahrzeug 16 gebildet, wie es auch in Fig. 2 verdeutlicht ist. Bei dem jeweiligen Panzerfahrzeug 16 ist der Panzerturm durch eine Fahrerkabine 18 ersetzt. Wie aus Fig. 2 ersichtlich ist, ist die Fahrerkabine 18 auf schockabsorbierenden Dämpfungselementen 20 gelagert. Die Fig. 2 verdeutlicht außerdem, daß der Bodenbereich des Fahrgestells eine zusätzliche Panzerung 22 und daß der Innenbereich der Wanne des Panzerfahrzeugs 16 eine zusätzliche Panzerung 24 aufweist.Mine clearance vehicle 12 and with a mine tracking vehicle 14. The mine clearance vehicle 12 and the mine tracking vehicle 14 are each formed by a modified armored vehicle 16, as is also illustrated in FIG. 2. In the respective armored vehicle 16, the armored turret is replaced by a driver's cabin 18. As can be seen from FIG. 2, the driver's cabin 18 is supported on shock-absorbing damping elements 20. FIG. 2 also illustrates that the base area of the chassis has additional armor 22 and that the inner area of the tub of armored vehicle 16 has additional armor 24.
An der Vorderseite des Minenräumfahrzeuges 12 ist eine Fräswalze 26 vorgesehen. Die Fräswalze 26 ist mit Meißelelementen 28 versehen, die von der Fräswälzen-Mantelfläche 30 radial wegstehen. Die Fräswalze 26 ist in einem Abschirmgehäuse 32 um eine horizonale Achse 34 zur Fahrtrichtung entgegengesetzt antreibbar, was durch den Pfeil 36 angedeutet ist. Die FräswalzeA milling drum 26 is provided on the front of the demining vehicle 12. The milling drum 26 is provided with chisel elements 28 which protrude radially from the milling drum surface 30. The milling drum 26 can be driven in a shielding housing 32 in the opposite direction to the direction of travel about a horizontal axis 34, which is indicated by the arrow 36. The milling drum
26 mit dem zugehörigen Abschirmgehäuse 32 ist an zwei seitlichen Tragarmen 38 gehalten, die am Minenräumfahrzeug 12 temporär befestigt, um eine horizontale Schwenkachse 40 verschwenkbar und somit in der Hohe bzw. zur Einstellung einer gewünschten Boden-Eindringtiefe verschwenkbar sind Der Antrieb der Fraswalze 26 und der Schwenkantrieb der Tragarme 38 erfolgt mittels einer Antriebseinrichtung 42, die im Heckbereich des Minenraumfahrzeuges 12 vorgesehen ist.26 with the associated shielding housing 32 is on two lateral support arms 38 held, which are temporarily attached to the mine clearing vehicle 12, pivotable about a horizontal pivot axis 40 and thus pivotable in height or for setting a desired depth of penetration. The milling drum 26 and the pivoting drive of the support arms 38 are driven by a drive device 42, which in Rear area of the mine vehicle 12 is provided.
Das Minenachsuchfahrzeug 14 ist von einem dem Minenraumfahrzeug 12 ähnlichen modifizierten Panzerfahrzeug 16 gebildet, das mit einer zweiten Fraswalze 44 lösbar kombiniert ist, die um eine Horizontalachse schwenkbeweglich vorgesehen ist, was durch den bogenförmigen Doppelpfeil 46 angedeutet ist Die zweite Fraswalze 44 ist mit einem Abschirmgehause 48 kombiniert, sie weist wie die erste Fraswalze 26 Meißelelemente 50 auf, die von der Mantelflache 52 der zweiten Fräswalze 44 radial wegstehen Der zweiten Fraswalze 44, die wie die erste Fraswalze 26 entgegen der Fahrtrichtung angetrieben wird, was durch denThe mine search vehicle 14 is formed by a modified armored vehicle 16 similar to the mine vehicle 12, which is detachably combined with a second milling drum 44, which is provided so as to be pivotable about a horizontal axis, which is indicated by the curved double arrow 46 combined, it has, like the first milling drum 26, chisel elements 50 which project radially from the lateral surface 52 of the second milling drum 44. The second milling drum 44, which, like the first milling drum 26, is driven counter to the direction of travel, which is caused by the

Fig 3 zeigt den Antriebsblock 58 des Minenraumfahrzeuges 12 in stark vereinfachter Darstellung. Der Antriebsmotor 60 ist durch die Abtriebs- oder Motorwelle 62 mit einer Kupplung 64 antriebsverbunden An die Kupplung 64 schließt sich das Pumpenverteilergetriebe 66 an Pumpenverteilergetriebe 66 und Kupplung 64 sind über einen Ubergangsring 68, der als glockenförmiges Gehäuse gebildet ist, eingefaßt. Das Pumpenverteilergetriebe 66 treibt Olpumpen 70 an, von denen eine erste für den linken Fahrantrieb 72, eine zweite für einen Kühler 74, eine dritte für eine Reserve 76 und die vierte für den rechten Fahrantrieb 72 des3 shows the drive block 58 of the mine vehicle 12 in a greatly simplified illustration. The drive motor 60 is connected to the clutch 64 by the output or motor shaft 62. The pump distributor gear 66 is connected to the clutch 64. The pump distributor gear 66 and the clutch 64 are framed by a transition ring 68, which is formed as a bell-shaped housing. The pump distributor gear 66 drives oil pumps 70, of which a first for the left drive 72, a second for a cooler 74, a third for a reserve 76 and the fourth for the right drive 72 of the
Minenräumfahrzeuges 12 eingesetzt istMine clearing vehicle 12 is used
Der Antriebsblock 58 umfaßt gemäß Fig. 3 einen zweiten Antriebsmotor 78, der in diesem Beispielsfall für den Antrieb der Fraswalzen 26 vorgesehen ist. Die Antriebsmotoren 60 und 78 sind vertikal übereinander im Minenraumfahrzeug 12 angeordnet. Es wird aber ausdrucklich betont, daß die Anordnung von zwei Antriebsmotoren 60 und 78 eine Möglichkeit zum Antrieb verschiedener Einrichtungen ist. Sämtliche Einrichtungen, wie Fräswalzen, Fahrantrieb, Kühler und dergleichen können auch von einem einzigen Antriebsmotor 60 beaufschlagt werden, wenn dieser Antriebsmotor 60 mit Kupplung und Pumpenverteilergetriebe entsprechend ausgebildet ist.According to FIG. 3, the drive block 58 comprises a second drive motor 78 which is provided for driving the milling drums 26 in this example. The drive motors 60 and 78 are arranged vertically one above the other in the minecraft 12. However, it is expressly emphasized that the arrangement of two Drive motors 60 and 78 is one way of driving various devices. All devices, such as milling drums, traction drive, cooler and the like, can also be acted upon by a single drive motor 60 if this drive motor 60 is designed accordingly with a coupling and a pump distributor gear.
Von dem zweiten Antriebsmotor 78 geht eine Abtriebswelle 80 zur Kupplung 82, die wiederum mit dem Pumpenverteilergetriebe 84 verbunden ist. Das Pumpenverteilergetriebe 84 treibt über entsprechende Olpumpen die Fräswalzen 26 an, von denen zwei als rechte und zwei als linke Fräswalzen eingesetzt werden.An output shaft 80 goes from the second drive motor 78 to the clutch 82, which in turn is connected to the pump distributor gear 84. The pump distributor gear 84 drives the milling drums 26 via corresponding oil pumps, two of which are used as right and two as left milling drums.
Mit dem Antriebsblock 58 sind Fahrgeschwindigkeiten bis runter zu 0,72 m/min realisierbar. Diese geringe Fahrgeschwindigkeit, die mit den üblichen Antrieben des Kampfpanzers nicht möglich sind, gewährleistet zusammen mit entsprechenden Arbeitsgeschwindigkeiten der Fräswalzen 26 ein optimales Räumen von Minen.With the drive block 58, travel speeds down to 0.72 m / min can be achieved. This low driving speed, which is not possible with the conventional drives of the main battle tank, together with the corresponding working speeds of the milling drums 26, ensures optimal clearing of mines.
Die Arbeitsgeschwindigkeiten der Fräswalzen 26 liegen zwischen 14 und 30 m/min. The working speeds of the milling drums 26 are between 14 and 30 m / min.
