CA 2660809

The present invention lies in the field of clearing bars (3) for the clearing blade (1) of a snow plough, which clearing bars are defined at least partially in cross section by a curved contour (10). They are based on the object of avoiding undesirable swirling of snow within the clearing blade (1). The invention is based on the finding that the snow is swirled on parts (7) of the fastening means (5) for fastening the clearing bar (3) to the clearing blade (1). To solve this problem, a design of the contour (10) that is optimized dynamically in terms of flow is described.

La présente invention concerne le domaine des barres d'usure (3) pour la lame de déblaiement (1) d'un chasse-neige, qui sont limitées en section transversale au moins en partie par un contour courbe (10). Elles ont pour objet d'éviter des tourbillonnements de neige indésirables à l'intérieur de la lame de déblaiement (1). L'invention repose sur le fait que la neige est amenée à tourbillonner au niveau de la lame de déblaiement (1) sur des parties (7) des moyens de fixation (5) pour la fixation de la barre d'usure (3) sur la lame de déblaiement (1). Pour résoudre ce problème, on décrit une configuration du contour (10) optimisée en termes de dynamique d'écoulement.
