Description
den Funktionselemente, insbesondere die Wandungen der Fahrgestellwanne in starke Vibration versetzt werden. Diese Vibrationen führen zu einer starken Beeinträchtigung der hochempfindlichen optischen und elektronischen Geräte des Kampffahrζeugs und äußern sich durch starken Lärm, durch den einerseits die Besatzung im Innern des Kampffahrzeugs in ihrer Konzentrationsfähigkeit beeinträchtigt wird, andererseits der Kampfwert des Fahrzeugs reduziert wird, da es bereits auf weite Entfernungen akustisch ortbar ist.the functional elements, especially the walls the chassis pan can be caused to vibrate strongly. These vibrations lead to a strong Impairment of the highly sensitive optical and electronic equipment used in combat vehicles and are expressed by strong noise, by the one hand the crew inside the combat vehicle their ability to concentrate is impaired, on the other hand their combat value of the vehicle is reduced, as it can be located acoustically over long distances.
Ss ist zwar schon bekannt, neben dem Triebradkranz einen mittels Gummi elastisch abgefederten Ring anzuordnen, auf dem die Gleiskette gedämpft aufläuft. Diese Anordnung hat jedoch den Nachteil, daß der zur Dämpfung geeignete Gummi verhältnismäßig weichelastisch ist, so daß sich in der unter dem Ring befindlichen Gummiabstützung ein im Betrieb umlaufender Knetwulst bildet, wodurch das Gummimaterial eine so starke Aufheizung und mechanische Beanspruchung erfährt, daß es durch frühzeitige Ermüdung unbrauchbar wird.Ss is already known, in addition to the drive wheel rim, a ring that is elastically cushioned by means of rubber to be arranged on which the crawler runs steamed. However, this arrangement has the disadvantage that the rubber suitable for damping is relatively flexible, so that in the under The rubber support located on the ring forms a kneading bead that runs around during operation, as a result of which the rubber material experiences such a strong heating and mechanical stress that it through premature fatigue becomes unusable.
ORIGINAL INSPECTEDORIGINAL INSPECTED
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Dämpfung der in das Triebrad bzw. Umlenkrad einlaufenden Gleiskette zu schaffen, die bei geringem Herstellungsaufwand eine lange Betriebsdauer ermöglicht.The invention is based on the object of a device for damping the in the drive wheel or deflection wheel incoming crawler belt to create the with little manufacturing effort allows a long service life.
Diese Aufgabe wird durch die im Kennzeichen des Hauptanspruchs angegebenen Merkmale gelöst, wobei sich der besondere Vorteil ergibt, daß vorhandene Gleisketten-Laufwerle mit geringem Aufwand nachgerüstet \ferden können.This object is achieved by the features specified in the characterizing part of the main claim, with the particular advantage that existing crawler drives with little Retrofitted effort.
In einer bevorzugten Ausführungsform ist der Dämpfungsring elastisch verformbar gestaltet, so daß er im Betrieb die Form eines Ovals annimmt. Die Sndverbinder kommen dadurch im Einlaufbereich früher mit dem Dämpfungsring in Kontakt, wobei bereits ein Teil der Aufschlagenergie durch die Federwirkung des elastischen Dämpfungsringes kompensiert wird.In a preferred embodiment, the Damping ring designed to be elastically deformable, so that it assumes the shape of an oval during operation. This means that the end connectors come into contact with the damping ring earlier in the inlet area Contact, whereby part of the impact energy is already due to the spring action of the elastic Damping ring is compensated.

Die Fig. 1 zeigt ein Triebrad 1 mit einer umlaufenden Gleiskette 2, die sich im wesentlichen aus Kettengliedern 3 und Endverbindern 4 zusammensetzt, mit denen die Kettenglieder miteinander verbunden sind. Das Triebrad 1 besteht im wesentlichen aus einer Triebradtrommel 5 und zwei Triebkränzen 6 und 7 (Fig. 2), mit denen die Gleiskette 2 mit ihren Endverbindern 4 in Singriff steht.Fig. 1 shows a drive wheel 1 with a revolving Crawler chain 2, which is composed essentially of chain links 3 and end connectors 4, with which the chain links are connected. The drive wheel 1 consists in essentially from a drive wheel drum 5 and two drive rings 6 and 7 (Fig. 2), with which the crawler belt 2 with its end connectors 4 is in singriff.
Zwischen den Triebkränzen 6 und 7 ist auf der Triebradtrommel 5 ein Dämpfungsring 8 angeordnet, der, wie aus Fig. 2 zu ersehen, eine umlaufende Rille 9 zur Aufnahme der an den Kettengliedern befindlichen Führungszapfen 10 aufweist.Between the drive rings 6 and 7, a damping ring 8 is arranged on the drive wheel drum 5, which, as can be seen from Fig. 2, a circumferential groove 9 for receiving the on the chain links has located guide pin 10.

Di ^ Fig. 3 zeigt eine andere Ausführungsform, bei der anstelle eines Dämpfungsringes zwei einzelne Dämpfungsringe 8' und 8·' auf der Triebradtrommel 5 abwälzen.Di ^ Fig. 3 shows another embodiment, instead of one damping ring, two single ones Damping rings 8 'and 8 ·' on the drive wheel drum 5 roll off.
Da der Innendurchmesser des Dämpfungsringes 8 bzw. der Dämpfungsringe 8r und 81' größer als der Außendurchmesser der Triebradtrommel 5 ist, nimmt der Dämpfungsring infolge der Kettenumschlingung eine zum Triebrad 1 exzentrische Lage ein, bei der er auf der Triebradtrommel 5 in einer durch den Punkt A gekennzeichneten Winkelstellung zur Auflage kommt, die er auch während des Betriebs im wesentlichen beibehält.Since the inner diameter of the damping ring 8 or the damping rings 8 r and 8 1 'is larger than the outer diameter of the drive wheel drum 5, the damping ring assumes an eccentric position to the drive wheel 1 as a result of the chain looping, in which it is on the drive wheel drum 5 in a through the Point A marked angular position comes to rest, which he essentially maintains during operation.
Der Innendurchmesser des Dämpfungsringes 8 bzw. der Dämpfungsringe 8' und 8'' ist ferner auf die Kettenteilung und den Umschlingungswinkel der Gleiskette derart abgestimmt, daß die in das Triebrad 1 einlaufende Gleiskette mit ihren Endverbindern 4 zunächst in einer durch den Punkt B gekennzeichneten festen Winkelstellung auf dem Dämpfungsring aufsetzt.The inner diameter of the damping ring 8 or the damping rings 8 'and 8' 'is also on the chain pitch and the wrap angle matched the crawler belt so that the crawler belt entering the drive wheel 1 with their end connectors 4 initially in a fixed angular position indicated by point B. touches the damping ring.

Dabei wird der Dämpfungsring verschwenkt, wodurch die ablaufende Kette etwa in der durch den Punkt C gekennzeichneten Winkelstellung angehoben wird. Auf diese Weise wird die in den Endverbindern enthaltene Aufschlagenergie zur Anhebung der unter Spannung stehenden, ablaufenden Kette verbraucht, wodurch ein verzögerter, weicherer Einlauf in die Triebkränze 4 und 5 des Triebrades 1 erreicht wird. Diese Wirkung kann noch dadurch verbessert werden, daß der Dämpfungsring 8 bzw. die Dämpfungsringe 8l und 8 '' elastisch verformbar ausgelegt sind, wodurch sie im Betrieb eine ovale Form einnehmen und im Sinlaufbereich zusätzlich die Funktion einer schlagdämpfenden Feder übernehmen.In doing so, the damping ring is pivoted, as a result of which the running chain is raised approximately in the angular position indicated by point C. In this way, the impact energy contained in the end connectors is used to raise the tensioned, unwinding chain, whereby a delayed, softer entry into the drive rings 4 and 5 of the drive wheel 1 is achieved. This effect can be further improved in that the damping ring 8 or the damping rings 8 l and 8 ″ are designed to be elastically deformable, whereby they assume an oval shape during operation and also take on the function of a shock-absorbing spring in the running area.
In entsprechender Vie is e erfolgt der Betrieb eines mit einem Dämpfungsring ausgestatteten Umlenkrades.The operation of one equipped with a damping ring takes place in a corresponding manner Deflection wheel.
