| 摘要 |
The invention relates to an anti-skid stud consisting of a plug-like piece, equipped with a fastening flange, to be installed in the tread of a vehicle tire, the plug-like anti-skid stud being made of a resilient basic material (3) of the type of tire-tread rubber or of some other suitably hard type, the basic material containing fragments of a granular or some other form, i.e. frictiion fragments (2), which are fastened to the basic material (3) of the anti-skid stud by diffusion or by some other state-of-the art method. The friction fragments in the tip surface (1) of the anti-skid stud become replaced during wear and produce roughness, as if there were numerous small anti-skid studs in the tip surface of each anti-skid stud, and thereby cause a grip against even a thin layer of ice on road surface; however, owing to their small separate piercing forces they will not cause a strong wearing effect on the road surface during driving on a road free of snow and/or ice. |
