Abstract

La présente invention a pour objet une aiguille pour appareil de voie caractérisée en ce qu'elle comporte un tracé géométrique arrangé pour former, sur l'ensemble de sa longueur, au moins un angle avec l'axe principal de déplacement d'une roue de véhicule impactant l'aiguille en un point considéré, l'angle formé présentant une variation discontinue sur la longueur de l'aiguille de telle sorte que cet angle génère une force d'impact inversement proportionnelle à la probabilité de l'impact entre une roue de véhicule et l'aiguille au point considéré.

Figure imgaf001
The present invention relates to a needle for a switchgear characterized in that it comprises a geometric pattern arranged to form, over its entire length, at least one angle with the main axis of movement of a wheel of vehicle impacting the needle at a point considered, the formed angle having a discontinuous variation along the length of the needle so that this angle generates an impact force inversely proportional to the probability of the impact between a wheel of vehicle and the needle at the point considered.
