<p>The tyre chain is composed of chain links (1, 2) which are arranged upright and, respectively, horizontally and form meshes composed in each case of four chain links (1) which are arranged upright and are joined to one another by a chain link (2) which is arranged horizontally. The mesh area bounded by adjacent junction points (4) and the free link-aperture area bounded by the chain link (2) which is arranged horizontally and is elongate, are essentially of the same size. By this means, uniform wear of the tyre is achieved. Due to the elongate design of the chain links (2) forming the junction points (4) a considerable saving in chain links is achieved for a given chain length. The tyre chain is of a low weight, as a result of which small centrifugal forces and only a low degree of inner wear of the tyre chain occur during driving. The elongate chain links (2) rotate with their longitudinal axis in each case in the direction of the main force component, as a result of which a self-tightening effect is achieved. <IMAGE></p> |
