A chain link for antiskid chains of vehicle tires, which is provided in order to improve the grip properties, in particular on a smooth underlying surface, with one or more spike(s) which project on one of its sides. Each spike has, perpendicular to its longitudinal extent, a cross-section whose outer edge has a corrugated peripheral contour of successive troughs and peaks. |

1. A chain link for antiskid chains of vehicle tires, comprising an underside which, when the antiskid chain is fitted on a vehicle tire having a tire tread, is supported on said tire tread, and an upper side facing away from the tread, with at least two spikes being attached to the chain link on the upper side thereof and protruding therefrom, for improving the grip properties on a smooth underlying surface, each spike having a length and a longitudinal central axis, each of said spikes being mutually offset sideways in a longitudinal direction of the chain link and are inclined, in the installed state of the antiskid chain, at an angle in the range from 78° to 70° to the tire tread, wherein a cross-sectional area of each spike is continuous for the length of the spike and in a top view has a contour with an outer edge which has a configuration with at least six successive pairs of a trough and an adjacent peak circumferentially, and wherein each trough has a radially inner section and the radially inner sections of the troughs of each spike are in the shape of a circular arc, and wherein each peak has a radially outward section and the radially outward sections of each peak are in the shape of a circular arc, wherein the two circular-arc shapes of each trough and adjacent peak extend into one another tangentially at respective arc ends of said each trough and adjacent peak. |
