Abstract

L'invention porte sur une chenille élastique qui est configurée de telle sorte qu'une augmentation de la vibration d'un dispositif de déplacement du type à chenilles, pendant le déplacement, ne se produit pas ou est réduite à un minimum, et de sorte qu'il est possible d'empêcher une fissure de se propager à l'intérieur, même si une courroie de déplacement de roue est endommagée, empêchant ainsi la séparation d'un noyau métallique. Une chenille élastique (1) est configurée de telle manière que des noyaux métalliques (2) sont incorporés dans un corps de chenille (4), et que des courroies de déplacement de roues (12), sur lesquelles se déplacent les roues d'un dispositif de déplacement du type à chenilles ayant la chenille élastique (1) montée sur celui-ci, sont respectivement disposées des deux côtés du côté périphérique interne de la chenille élastique (1) dans la direction de la largeur de celle-ci. Dans la chenille élastique, les noyaux métalliques ont des sections aile (14) s'étendant vers les deux extrémités de la chenille élastique (1), les extrémités étant situées des deux côtés de la chenille élastique (1) dans la direction de la largeur de celle-ci. La chenille élastique possède des éléments de renfort (3) incorporés à l'intérieur de celle-ci, les éléments de renfort (3) étant disposés entre les courroies de déplacement des roues et les sections aile qui chevauchent les courroies de déplacement des roues quand la chenille élastique est vue du côté périphérique interne. Les éléments de renfort sont formés sous une forme du type courroie entre les courroies de déplacement des roues et les sections aile qui chevauchent les courroies de déplacement des roues. Les éléments de renfort sont souples et ont une résistance à la traction supérieure à celle du caoutchouc qui forme le corps de chenille.
