Title (EN) TIRE CHAIN HAVING IMPROVED TRACTION
(FR) CHAINE POUR PNEU AYANT UNE TRACTION AMELIOREE
Abstract: front page image
(EN)A cable type tire chain (10) has traction sleeves (16) on the cross members (14) located only adjacent to the shoulders (40) of the tire (20). The center portion (42) of the cross members adjacent to the middle of the tire tread is free of traction sleeves. The traction sleeves are spaced away from the middle of the tire tread by either a coil spring (46) through which the cross member cable (28) extends or by beads (52) attached to the cable. The cross members are attached directly to the side members (12) of the tire chain by flat profile hooks (26) formed from rectangular strips of metal, so that the cross members lie close to the sidewalls (50) of the tire. The invention provides improved traction and reduced wear of both the tire and the tire chain.
(FR)Une chaine de pneu du type a cable (10) possede des douilles de traction (16) sur les elements transversaux (14), situes seulement adjacents aux epaulements (40) du pneu (20). La partie centrale (42) des elements transversaux adjacents a la partie mediane de la semelle du pneu est exempte de douille de traction. Les douilles de traction sont espacees du milieu de la semelle du pneu soit par un ressort en spirales (46) au travers duquel le cable de l'element transversal (28) s'etend ou par des perles (52) attachees au cable. Les elements transversaux sont attaches directement sur les elements lateraux (12) de la chaine de pneu par des crochets a profil plat formes a partir de languettes rectangulaires de metal, de maniere a ce que les elements transversaux soient rapproches des parois laterales (50) du pneu. Ce dispositif assure une meilleure traction et une usure moindre a la fois du pneu et de la chaine.
