Abstract

L'invention concerne une lame d'aiguille (1) destinée à être utilisée dans un aiguillage. La lame d'aiguille comprend un champignon (5) de rail, une âme (6) de rail et un patin (7) de rail. La lame d'aiguille (1) comporte une première section longitudinale prévue pour venir en appui sur une contre-aiguille (2) et une deuxième section longitudinale située à l'extérieur de la zone d'appui. La lame d'aiguille (1) comporte dans la deuxième section longitudinale un profil de base de section transversale. Un axe médian s'étendant de manière verticale est défini par le centre du champignon (5) de rail dans la deuxième section transversale dans la section transversale. Et une première section (10) du patin (7) de rail est disposée sur un premier côté de l'axe médian, et une deuxième section (11) du patin (7) de rail est disposée sur un deuxième côté, faisant face au premier côté, de l'axe médian. La largeur de la première section (10) du patin (7) de rail est plus grande dans la section transversale que la largeur de la deuxième section (11) du patin (7) de rail. La section transversale de la lame d'aiguille (1) présente sur au moins un emplacement le long de l'extension longitudinale de rail un rapport entre le moment d'inertie surfacique vertical l y et le moment d'inertie surfacique horizontal l x, qui est supérieur à 0,5, de manière préférée supérieur à 0,6, de manière particulièrement préférée supérieure à 0,7.
