But this device has the disadvantage that the rubber, which is suitable for ensuring the damping has a relatively weak elastic force, so that it forms in this support rubber, arranged under the ring, a plastic bead that turns during the walk , so that the rubber undergoes a heating and mechanical stress so strong that it wears prematurely

Dans une forme de réalisation avantageuse, la bague d'amortissement est déformable élastiquement, de sorte qu'en service elle prend une forme ovale. Ainsi, les éléments de jonction viennent plus tôt en contact avec la bague dans la zone d'engagement et, par suite, une partie de l'énergie de In an advantageous embodiment, the damping ring is elastically deformable, so that in service it takes an oval shape. Thus, the joining elements come into contact with the ring earlier in the engagement zone and, consequently, a part of the energy of

L'invention sera décrite plus en détail en regard du dessin annexé à titre d'exemples nullement limitatifs, et sur lequel: la figure 1 représente schématiquement en élévation latérale une roue motrice-en prise avec la chenille; la figure 2 est une coupe transversale de la roue motrice par la ligne II-II de la figure 1; et la figure 3 est une coupe transversale, analogue à The invention will be described in more detail with reference to the accompanying drawing by way of non-limiting examples, and in which: Figure 1 shows schematically in side elevation a drive wheel-engaged with the crawler; Figure 2 is a cross section of the drive wheel by the line II-II of Figure 1; and FIG. 3 is a cross-section, analogous to
celle de la figure 2, d'une autre forme de réalisation. that of Figure 2, of another embodiment.
La figure 1 représente une roue motrice 1, sur laquelle passe une chenille 2, qui est composée essentiellement de FIG. 1 represents a driving wheel 1, on which a track 2, which consists essentially of
maillons 3 et d'éléments de jonction 4 reliant ces maillons 3. links 3 and connecting elements 4 connecting these links 3.
La -roue motrice 1 est composée essentiellement d'un tambour 5 The driving wheel 1 is essentially composed of a drum 5

Une bague amortisseuse 8 est disposée sur le tambour 5 entre les couronnes 6 et 7 et, ainsi que le représente la figure 2, elle comporte une gorge périphérique 9 destinée à A damping ring 8 is disposed on the drum 5 between the rings 6 and 7 and, as shown in Figure 2, it comprises a peripheral groove 9 intended for

lons 3.lons 3.
La figure 3 représente une autre forme de réalisation, dans laquelle ce sont deux bagues amortisseuses 8' et 8", au lieu d'une seule, qui entourent le tambour 5. Comme le diamètre intérieur de la bague 8 (ou des bagues 8t et 8") est plus grand que le diamètre extérieur du tambour 5, cette bague prend, par rapport à la roue motrice 1, sous l'effet de l'arc d'enroulement de la chenille, une position excentrée, dans laquelle elle vient s'appliquer contre ce tambour 5 à une position angulaire indiquée par la flèche A, qu'elle conserve sensiblement, même pendant le fonctionnement. Par ailleurs, le diamètre intérieur de la bague 8 (ou des bagues 8' et B") est déterminé par rapport au pas de la chenille et à l'angle d'enroulement de cette chenille 2, de façon que les éléments de jonction 4 de cette dernière, FIG. 3 shows another embodiment, in which two damping rings 8 'and 8 ", instead of one, surround the drum 5. As the inside diameter of the ring 8 (or rings 8t and 8 ") is greater than the outer diameter of the drum 5, this ring takes, relative to the driving wheel 1, under the effect of the winding arc of the track, an off-center position, in which it comes apply against this drum 5 to an angular position indicated by the arrow A, which it substantially keeps, even during operation. Furthermore, the inside diameter of the ring 8 (or rings 8 'and B ") is determined relative to the pitch of the track and to the winding angle of this track 2, so that the connecting elements 4 of the latter,

Cela fait pivoter la bague amortisseuse 8 (ou les bagues 8' et 8"), si bien que, à la sortie, la chenille 2 est soulevée à peu près à la position angulaire indiquée first on this ring 8, 8 'or 8 "at an angular position indicated by the arrow B. This rotates the damping ring 8 (or the rings 8' and 8"), so that at the exit, caterpillar 2 is raised to approximately the indicated angular position

Il est possible d'améliorer encore cette to the tended crawler at its exit, which puts it in gear later and more slowly with the crowns 6 and 7 of the drive wheel 1. It is possible to further improve this
