Title (EN) ANTI-SKID STUD
(FR) CRAMPON ANTI-DERAPAGE
Abstract:
(EN) The invention relates to an anti-skid stud the operation of which is based on a larger than conventional diameter of the tip part (1) of the anti-skid stud and on its primarily annular contact with the road surface during normal driving, with a slight projection of the tip and with a small surface pressure, the projection increasing in situations in which it is needed, for example during braking, the external force P caused by the braking tilting the anti-skid stud in its position, whereupon the projected edge (5) of the tip part will penetrate over its entire width into the road surface.
(FR) L'invention se rapporte à un crampon anti-dérapage dont l'efficacité est basée sur un diamètre de la partie de tête (1) supérieur à celui des crampons classiques et sur le contact d'abord annulaire avec la surface de la route en conduite normale, la tête formant une légère saillie et la pression superficielle étant faible; la saillie augmente dans des situations dans lesquelles elle est nécessaire, par exemple, pendant le freinage, la force extérieure P provoquée par le freinage inclinant le crampon anti-dérapage sur sa position; de ce fait, la saillie projetée (5) de la partie de tête pénètre sur toute sa largeur dans la surface de la route.
