Abstract

L'invention concerne une roue à labyrinthe de poussière sans axe comprenant un bord intérieur à l'intérieur d'un bord extérieur qui tournent l'un par rapport à l'autre par l'intermédiaire de rouleaux disposés à l'intérieur d'une cage à billes. Un élément d'interface avec le sol est disposé de manière circonférentielle sur le bord extérieur et définit une partie de prolongement qui s'étend vers le bord intérieur. Un couvercle latéral est relié à l'un des bords intérieur et extérieur et recouvre une partie d'un premier côté de la roue sans axe opposée à un second côté et la partie de prolongement de l'élément d'interface avec le sol. Un labyrinthe de poussière comportant une section sur le premier côté de la roue sans axe est défini par la coopération entre des parties du bord intérieur, du bord extérieur et du couvercle latéral. Une section sur le second côté de la roue sans axe est définie par la coopération entre des parties du bord intérieur, du bord extérieur et de la partie de prolongement de l'élément d'interface avec le sol.
