Abstract

L'invention concerne une roue élastique dans laquelle un élément auxiliaire élastique est fixé à la surface latérale du bord de la roue, et soit un élément de type plaque fixé à la surface de l'extrémité extérieure de celui-ci est maintenu pour obtenir un déplacement radial de la roue entre des éléments d'inhibition fixés à la surface périphérique extérieure d'un disque, ou au moins une partie d'un élément annulaire, installée sur la surface latérale du bord de la roue fait saillie vers l'intérieur, au-delà de la surface périphérique intérieure du bord de la roue. Un membre auxiliaire élastique constitué de corps élastiques caoutchouteux et des plaques d'acier stratifiées de manière alternative l'une à l'autre sont fixées à l'extrémité en saillie de l'élément annulaire présentant des extrémités opposées à l'élément auxiliaire élastique fixé à l'élément d'inhibition fixé au disque, ou l'extrémité frontale d'un caoutchouc bloqueur fixé à une surface latérale de la saillie aboute contre la surface intérieure d'un guide, ce qui permet d'obtenir des performances améliorées au niveau de la conduite, de l'amortissement des vibrations et du son, tout en restant durable, fiable et stable au niveau de la direction, à tout moment, que l'alimentation soit fournie en grande ou en petite quantité.
